Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention provides a movable piece that can be converted into a first state in which it does not accept a batted ball and a second state in which it easily accepts a batted ball by an electric drive source. The present invention relates to a pachinko machine having a variable winning device.

(Prior Art) Conventionally, a game board is divided by guide rails to form a game area, and a large number of guide nails are arranged within the game area, and an electric drive source is installed approximately in the center of the game area. A variable prize-winning device is provided in which movable pieces that can be converted between a first state in which it does not accept a batted ball and a second state in which it is easy to accept a batted ball are pivoted in an opposed manner, and below the variable prize-winning device in the gaming area, a state in which a batted ball wins a prize is provided. A pachinko machine is known in which a specific winning device is provided for the electric drive source to generate an actuation signal for converting the movable piece from the first state to the second state.

(Problems to be Solved by the Invention) Generally, in the above-mentioned type of pachinko machine equipped with a variable prize winning device, if the length from the rotational center axis of the movable piece is R, the rotational movement of the movable piece Because of the need to prevent this from interfering with the direction of the ball, it is not possible to actively provide an obstacle member that would affect the direction of the ball falling within the sector of the rotation radius R. If the movable piece is in the first state in which it cannot receive the ball due to the impossibility of providing this obstacle member, the direction of the downward motion of the ball flowing down the side of the variable prize winning device will be linear, and the inside of the gaming section As the time of existence in
A problem arises in that the game becomes monotonous, reducing the interest of the pachinko game. In addition, when the movable piece has changed to the second state where it can easily accept a batted ball, the downward momentum of the batted ball is strong, so the ball goes wild on the surface of the movable piece, causing damage to the movable piece, especially its stopper. A large impact load is applied to the movable piece, resulting in a decrease in durability, and a problem arises in that the ball that falls onto the surface of the movable piece bounces back and damages the front glass.

This inconvenience seems to be solved by shortening the length of the movable piece, but it is possible to change the movable piece from the first state to the second state by winning a prize below the movable winning device in the gaming area.
In a pachinko machine equipped with a specific winning device that changes the state, if the length of the movable piece is made shorter than necessary, the ball that is hit will enter the specific winning device and the movable piece will change from the first state to the second state. Even if the state is changed, the probability that the ball will be picked up by the movable piece is extremely low. The final goal of this pachinko game is to:
Enter the batted ball into the special prize opening in the variable prize winning device,
The purpose is to generate a special game state in which the winning rate is greatly improved. However, the winning rate in the second state is low, and the occurrence of a special game state due to a winning ball hitting the variable winning device is not necessarily guaranteed and is highly coincidental. In short, the player's chance of obtaining a large number of commercial balls becomes extremely low, and the pachinko game loses its interest.

The present invention has been made in view of such problems, and provides a pachinko machine in which the length of the movable piece of the variable prize winning device can be made shorter than in the past without reducing the winning probability of the ball hit under the second state. The purpose is to provide.

(Means for Solving the Problems) The present invention determines the length of the movable piece 11 of the variable winning device 10 so that it protrudes laterally longer than the diameter of the game ball when converted to the second state, while In the gaming area 3, there is a distance that does not interfere with the conversion operation of the movable piece 11 and is less than or equal to the diameter of the game ball from the tip of the movable piece in front of the movable piece 11 when the movable piece 11 is converted to the second state. A side member 5A is disposed at a position separated by L, and a channel forming member 5B is disposed for guiding the game ball from above the side member 5A toward the outside side of the side member, When the movable piece 11 is in the first state, the flow of game balls is passed through the first flow path (arrow P1) toward the outer side of the side member 5A, the movable piece 11 and the side member On the other hand, when the movable piece 11 changes to the second state, the second flow path is closed by the movable piece 11, As a result, the variable winning device 10 moves along the movable piece 11 from the winning winning area 15 above the side member 5A.
A third flow path (arrow P3) for guiding the game ball is formed inside.

(Function) When the movable piece 11 changes to the second state and closes the second flow path P2, the side member 5A is located further forward than the tip of the movable piece 11.
A cooperates with the movable piece 11 to guide the game ball into the variable prize winning device 10 over a range longer than the length of the movable piece 11. In other words, regarding the probability of winning a prize picked up by the movable piece 11, the same function as the conventional movable piece can be achieved by using a shorter movable piece 11. Therefore, the area within the radial locus where the movable piece 11 rotates becomes smaller, and correspondingly, the game area 3 of the game board becomes larger than before. Nails or other obstructions can also be provided in areas of the game board that could not be provided for security reasons.

(Example) Hereinafter, the present invention will be explained based on an example of a pachinko machine shown in the drawings.

In FIG. 1, reference numeral 10 denotes a variable prize winning device, which is arranged approximately in the center of a gaming area 3 divided by a guide rail 2 of a gaming board 1. In the gaming area 3, there is also a general winning device 4, a large number of guide nails 5,
A windmill 6, an out hole 7, etc. are provided. Below the variable winning device 10, a total of three specific winning devices, that is, first specific winning devices 8, 8 on the left and right and a second specific winning device 9 in the center are arranged side by side. In this embodiment, the variable prize winning device 10 has two left and right movable pieces (main movable pieces) that can be converted into a first state (FIG. 2) in which it does not accept a batted ball and a second state (FIG. 3) in which it easily accepts a batted ball. 11, it also has two left and right movable pieces (auxiliary movable pieces) 12 that interlock with the main movable piece with a time difference. The guide nails 5 include side nails 5A, one on each side of the left and right sides of the variable winning device 10, and a group of guide nails 5B that guide the game ball toward the outside of the side nails. , but need not necessarily be constituted by nails, the former by suitable side members and the latter by guide nails 5B.
It is also possible to use a member other than a nail, which functions as a channel forming member.

The main movable piece 11 and the auxiliary movable piece 12 of the variable prize winning device 10 rotate around a main movable shaft 13 and an auxiliary movable shaft 14 (FIG. 4), which will be described later, to convert to the second state. In particular, when the main movable piece 11 is converted to the second state, as shown in FIG. 3, it protrudes to the side of the variable winning device longer than the diameter of the game ball. Each side nail (side member) 5A is designed so that the main movable piece 11 does not obstruct the conversion operation of the main movable piece 11 and that the main movable piece 11
When the main movable piece 11 is at rest, there is a distance L in front of the main movable piece 11 that is less than the diameter of the game ball from the tip of the main movable piece.
(Fig. 3).

Therefore, when the main movable piece 11 is in the first state (FIG. 2) in which it does not accept a batted ball, the following first
A flow path and a second flow path are formed. That is, between a group of guide nails (flow path constituent members) 5B and the variable winning device 10, the game ball passes from above the side nails 5A toward the outer side of the side nails 5A. The first flow path (arrow P1), the main movable piece 11 and the side nails 5
This is a second flow path (arrow P2) formed between the flow path A and the flow path above which is the winning possible area 15 for the variable winning device 10 under the second state.

On the other hand, the main movable piece 11 has a second movable piece that can easily receive the ball.
When the state is changed to the state (FIG. 3), the second flow path is closed by the main movable piece 11 on the game board surface of FIG.
1, a third flow path (arrow P3) is formed along which the game balls are guided into the variable prize winning device 10. In other words, the main movable piece 11 functions to switch between the second flow path P2 and the third flow path P3.

The side nails 5A are located further forward than the tip of the main movable piece 11 when the main movable piece 11 changes to the second state and closes the second flow path P2 and opens the third flow path P3. , the side nails 5A cooperate with the movable piece 11,
The game balls are guided into the variable winning device 10 over a width that is longer than the length of the main movable piece 11. In other words, regarding the winning probability of a batted ball under the second state, the same function of the movable piece as in the past can be achieved by using the shorter main movable piece 11. In this way, the lateral nail 5
By giving A the effect of enlarging the winning area of the movable piece 11, the length of the main movable piece 11 can be shortened. Due to this shortening. The area within the radial trajectory of the main movable piece 11 is reduced, and correspondingly, the gaming area 3 of the game board is expanded compared to before, and the free rotation of the main movable piece 11 is not obstructed in the past. Nails or other obstructing members can be provided even in areas of the game board that cannot be provided due to the need to do so. For example, considering the width of the game board 3 in the horizontal direction, there is one main movable piece 11 on each side, so even if we take L = 10 mm as the gap of approximately 11 mm or less in diameter of the game board, it will be approximately The horizontal playing area of the game board is expanded by 20 mm, increasing the degree of freedom in arranging obstacle members. This is important as a technique that leaves the original area of the game board as large as possible, as variable winning machines are becoming larger. In addition, since the main movable piece 11 may be shorter,
The capacity of the drive source such as an electromagnetic solenoid for driving this can also be small, and the variable prize winning device 10 can be configured to be relatively compact as a whole.

Variable winning device The configuration of the variable winning device 10 will be schematically explained in FIGS. 2 and 3.

20 is a board of the variable prize winning device 10, on which a vertically long window portion 21 is formed. On the top of the board 20,

A rear-open transparent case 70 is attached to the rear surface 37 of the recessed chamber 35 as a rear surface member, and the rear opening of the recessed chamber 35 is covered by the transparent case. In the transparent case 70, which is the rear member, there is a concave chamber 3.
A background carrier 73, which is a component of a background display device 77 for moving and displaying a game background on the back surface of the player 5, is built-in. Reference numeral 76 denotes a motor for rotating the background support 73 via the gear device 75, and is a component of the background display device 77.

The rear-opening transparent case 70 is covered by a support plate 78, and a metal drive source mounting plate 80 is attached to the back surface of the support plate. The drive source mounting plate 80 carries an electric drive source (first drive source) 87 for independently moving a set of left and right movable pieces including the main and auxiliary movable pieces 11 and 12. There is. In this embodiment, this first drive source 87
consists of an electromagnetic solenoid. Each plunger shaft 88 (FIG. 11) of these two electromagnetic solenoids 87 has a movable piece 11,
Plate-shaped operating lever 90 for converting operation of 12
are fixed, respectively. Each operating lever 90
is a pin 4 protruding from the movable levers 45 and 46.
It has a first engagement hole 93 and a second engagement hole 94 that engage with the holes 8 and 49.

In the conventional variable winning device, the electromagnetic solenoid which is the driving source of the variable winning device is separated from the variable winning device main body and directly installed on the back of the game board, and the shaft of the driving source is connected to the variable winning device through a link mechanism. Connected to a movable piece. Therefore, the connecting member becomes long and large, and it is necessary to use an electromagnetic solenoid with a large capacity. However, as shown in FIG. 2, if the first drive source 87 is provided integrally with the variable prize winning device main body,
12 can be shortened, and the entire device can be assembled compactly. In addition, the operating lever 9
Regarding the configuration of drive source 8, as described later,
7 and the movable pieces 11 and 12, and when assembling the pachinko machine, it is possible to ensure accurate and smooth interlocking between the drive source 87 and the pins 48 and 49 of the movable piece levers 45 and 46. It can be constructed so that it can be fitted and attached.

Hereinafter, the configuration of the variable prize winning device 10 will be explained in detail by dividing into the upper part, middle part, and lower part of the board 20.

Upper part of the board In FIGS. 4 and 5, a U-shaped ball receiving part 22 is provided at the top of the front side of the board 20, and the ball receiving part opens an opening 22A provided in the board 20. It is continuous with the ball lead-out portion 22B extending on the back surface of the substrate via the ball guide portion 22B. In addition, a window portion 2 is provided below the ball receiving portion 22.
Armor part 2 protruding in a gate shape slightly above the upper side of 1
3 is provided, and the upper surface 23A of the armor portion is connected to the substrate 2
It is gradually inclined lower toward the opening 23C provided at 0, and is configured to also function as a ball receiving part. Also, the upper surface of the armor portion 23, that is, the ball receiving portion 23A
is continuous with a ball lead-out portion 23D extending on the back surface of the substrate via an opening 23C provided in the substrate 20. The front sides of these ball receivers 22 and 23A are commonly covered by an upper front plate 24, and together with the upper front plate, constitute a top prize opening 16 and a side prize opening 17, respectively. A side surface 23B that hangs down from the upper side of the window section 21 of the armor section 23 to the upper side thereof forms a storage space for a special display member 101, which will be described later, together with the upper front plate 24.

Middle part of the board (a) Movable piece In Figures 4 and 10, the above main movable piece 1
1 includes a flat guide portion 11A extending outward and inward from the rotation base 11C, and a T-shape as a whole at the front end of the portion of the flat guide portion extending outward from the rotation base 11C. The first stopper part 11D is made up of a plate-shaped main part 11B provided in the main part 11B, a guide part extending inward from the rotating base part 11C where the plate-shaped main part does not exist, and It has a second stopper portion 11F that is bulged. A notch 11E is provided in the first stopper portion 11D from the front side so as not to impede the rotation of the auxiliary movable piece 12. Further, the second stopper portion 11F has an unformed space 11G inside to reduce the weight of the movable piece.

Conventionally, this main movable piece is simply a flat plate, and when the ball rides on the movable member, it is unstable and the ball gets damaged. There was also the problem that the loose ball could hit the glass and damage it. However, the main movable piece 11
In this way, instead of being composed only of the flat guide part 11A, the plate-shaped main part 11B is provided and the plate-shaped main part is made to protrude slightly above the flat guide part 11A, so that the winning ball is The protruding portion of the ball 11B suppresses the scattering of the ball, controls the direction of the ball, and guides the ball into the variable prize winning device 10 reliably and smoothly without hitting the glass of the pachinko machine. In other words, it stabilizes the ball and prevents it from going toward the glass. Therefore, since the winning (probability) to the special winning opening 19 is stabilized, a stable variable winning device can be provided, and the glass will not be damaged. Note that a movable piece decoration can be integrally provided on the plate-shaped main portion 11B by molding, adhesion, or the like.

On the other hand, the auxiliary movable piece 12 has a rotating base 12 having the same depth as the flat guide part 11A of the main movable piece 11.
A plate-shaped main portion 12A extending downward from the front end of C.
and a short stopper portion 12B hanging below the rotating base portion 12C. The plate-shaped main portion 12A protrudes slightly outward from the rotating base portion 12C,
This protruding portion corresponds to the notch 11 of the main movable piece 11.
It has entered E.

In this embodiment, the plate-like main parts 11B of the left and right main movable pieces are modeled after the "neck" and "tail" of a horse,
In addition, the plate-shaped main portions 12A of the left and right auxiliary movable pieces are
It is modeled after the front legs and hind legs of a horse.

The main movable piece 11 has a first stopper portion 11D.
As shown in FIG. 16, the auxiliary movable piece 2 comes into contact with the rotating base 12C and becomes closed, and
When in the open state, a second stopper portion 11F provided near the rotation base 11C on the lower surface of the guide portion 11A
, comes into contact with a half-cylindrical protrusion 28 which will be described later.

In the normal state in which the main movable piece 11 is in the closed position, the auxiliary movable piece 12 has a lower surface of the stopper portion 12B in contact with the outer side of the upper end of a U-shaped lower support frame 61, which will be described later, and the main movable piece 11 is in the open position. In this position, the upper surface of the stopper portion 12B abuts the lower end of the half-cylindrical projection 28.

(b) Movable shaft The main movable shaft 13 and the auxiliary movable shaft 14 are fixed by firmly fitting one end into the hole provided in the rotation bases 11C and 12C of both the main and auxiliary movable pieces 11 and 12. It is fixed to both movable pieces 11 and 12. In this case, as shown in FIG. 10, a flat part for positioning is provided at the front end of each movable shaft 13, 14 to correctly determine the relative positional relationship with respect to the movable piece. The retaining part 13 is formed by applying a retaining process to
By providing A, 14A, each movable piece 1
1, 12 and each of the movable shafts 13, 14 are strongly connected to prevent them from easily coming off the movable piece. At the other end of each movable shaft 13, 14, that is, at the rear end, lever fitting portions 13B, 14B have flat circumferential surfaces and correctly define the relative positional relationship with the mating member to be fitted. is provided, and
A groove is provided in the circumferential direction on the circumferential surface of the remaining notch to prevent the mounting parts 13C and 14 from falling off.
C is formed.

(c) Movable bearing section In FIGS. 4, 5, and 7, the main movable bearing section 25 and the auxiliary movable bearing section 26 are located vertically on both sides of the window section 21 in the middle of the front surface of the board. installed in parallel,
It extends long on the back surface of the substrate 20. Each of the movable shafts 13 and 14 is rotatably inserted into the bearing portions 25 and 26. In this case, in order to make the rotation of each movable piece 11, 12 smooth, liners 25A, 26A made of a material different from that of each movable shaft 13, 14 are provided as auxiliary materials in each bearing part 25, 26. be. In this embodiment, the liners 25A, 26
A is made of a brass cylinder provided over the entire length of the bearing portions 25 and 26, and each movable shaft 13 and 14 is chrome plated. liner 2
5A and 26A are integrally installed internally during molding, but they may be inserted into the movable member bearing later. By making the materials of the movable shafts 13, 14 and the bearing parts 25, 26 different from each other in this way, the frictional resistance between them is reduced, and the movable shaft 1
3 and 14 can be rotated smoothly. In addition to the materials mentioned above, for example, nylon or the like may be used for the liner as a material for reducing frictional resistance. Further, the liners 25A, 26A do not necessarily have to be provided over the entire length of the bearings, but may be provided in the form of bushes only on a portion of the bearing portions 25, 26, for example, at one end and the other end thereof.

Incidentally, a protrusion 29 extending rearward from the back surface of the board on the outside of the bearing parts 25 and 26 functions as a positioning part when attaching the variable prize winning device.

(d) Movable lever In FIGS. 2 and 7, when the above-mentioned movable shafts 13 and 14 are rotatably inserted into the bearings 25 and 26, the movable shafts 13 and 14 are The ends have a length that protrudes outside the bearing parts 25 and 26. The protruding ends of each movable shaft 13, 14, that is,
As already mentioned, the lever fitting portions 13B and 14B are provided at the rear end portion with flat notches on the circumferential surface. A main movable lever 45 and an auxiliary movable lever 46 are fixed to each of the lever fitting portions 13B and 14B, respectively. To be more specific, the bases of both the main and auxiliary movable levers 45, 46 are provided with through holes 45A, 46A having cross-sectional shapes corresponding to the lever fitting parts 13B, 14B,
Each lever fitting portion 13B, 14B is inserted into this through hole.
is inserted so that it cannot rotate. Further, a retaining ring 47 for preventing the movable shafts 13 and 14 from falling off protrudes from the rear end of each lever fitting portion 13B and 14B when inserted, and a retaining ring 47 is fitted to the attachment portions 13C and 14C for preventing the movable shafts 13 and 14 from falling off. . Both the main and auxiliary movable levers 45 and 46 have rearwardly extending pins 48 and 49 at their tips.
5 and 46 are arranged outside the operating perpendicular line of the plunger shaft 88 and toward the inside of the base plate 20. By arranging the movable lever 45 inward in this manner, the width of the operating lever 90, which will be described later, can be reduced. The relationship between the lever fitting part 13B of the main movable shaft 13 and the through hole 45A of the main movable piece lever 45 is such that the main movable piece lever 45 after installation moves the main movable piece 11 to the closed position (Fig. 2) by its own weight. ) The positional relationship is determined so as to give the main movable shaft 13 a rotational habit in the direction of . That is, when the main movable piece 11 is in the closed position, the main movable piece lever 45 is positioned inward and downward, as shown in FIG. On the other hand, the auxiliary movable lever 46 extends in the opposite direction to the direction in which the main movable lever 45 extends and is stable. This is done by using both movable levers 45 and 46.
This is to maintain a constant engagement relationship between the pins 48, 49 and the engagement holes 93, 94 of the operating lever 90.

(E) Middle front plate In FIG. 4, 30 indicates the movable bearing portions 25 and 26 on the left side of the window portion 21, the movable bearing portion 25 on the right side,
A middle front plate that bridges between 26 and 26,
The middle front plate 30 covers and hides the left and right movable bearing parts 25 and 26.

At the center of the back side of the middle front plate 30, a branch head 31 is formed as a component of a diverting shelf branching means for distributing winning balls to the left and right.
The branch head 31 is connected to a branch 41 of a branch shelf branch member 40 provided in the recessed chamber 35 (FIG. 6). The top surface of the branch head 31 is formed into a roof shape and protrudes from a distribution shelf 42, which will be described later, in order to distribute winning balls to the left and right.
The reason why the branching section head 31 is made to protrude from the diverting shelf 42 is to ensure that the ball that enters the variable winning device 10 hits the branching section head 31 and prevents the ball from flying out of the device again without winning a prize. This is to prevent this. If the branch head 31 is
At the same level as 2, when the main movable piece 11 is in the open state, the ball that is guided by the main movable piece 11 and enters the prize from the left or right goes straight over the branch head 31 and hits the opposite side ( pass through to the right or left),
This will cause the inconvenience of not winning a prize. Branch head 3
1 is the width between the inner ends of the main movable pieces 11, 11 when the main movable pieces 11, 11 are opened,
That is, the distance is set to be approximately the same as the distance between the first stopper portions 11D, 11D, or slightly shorter. This is because the main movable pieces 11, 11 have a guide portion 11A.
The winning ball that came to the stopper part 11D is placed in the concave chamber 3.
This is to enable smooth guidance to the special winning opening 19 inside or below 5.

The branch head 31 is formed as a box that is open to the rear as a whole, and is configured to also function as a storage portion for a right number display 43 consisting of a 7-segment LED display. Reference numeral 32 denotes a transparent display window for visually displaying the number of rights display 43 to the player. Generally, in the configuration in which the concave decoration is placed in the concave chamber 35, the space within the concave chamber becomes very narrow, making it difficult to provide a sufficiently large outlet for winning balls. For this reason, when a large number of winning balls are generated (during a special mode of the game), the balls may become clogged in the concave chamber, and it will take time to eject them.
However, if the decorations housed in the recessed chamber are provided on the front outside of the recessed chamber as described above, the actual operating space within the recessed chamber of the variable prize winning device is expanded accordingly, and the decorativeness can be appealed to players. In addition, since the upper part of the concave chamber is wider, the outlet for winning balls (diversion port 39A, which will be described later) can be provided with a sufficient size, allowing complete and prompt ejection of the balls. It becomes like this. As for the middle front plate 30, there is no space limitation compared to the concave interior decoration, so by using a large middle front plate, it is possible to make the variable prize winning device itself look large. In addition, 33 is the concave chamber 3
In order to prevent the game content in the recessed chamber 35 from being blocked from the player's view by the middle front plate 30, transparent window portions are provided on both sides of the display window 32 of the middle front plate 30. shows. By providing a transparent window 33 on at least a portion of the middle front plate 30, or by providing a visible member on the middle front plate 30, the player can check the ball in the recessed chamber 35.

The middle front plate 30 is fixed to the substrate 20 by screwing support protrusions 34 provided on the inner side surfaces of both ends thereof from the back surface of the substrate 20. By providing the middle front plate 30 in a removable manner, display means such as the right number display 43 consisting of a 7-segment LED display can be integrally provided and can be easily replaced. Furthermore, since this display means is located in the center of the variable prize winning device, it is easier for the player to see. As shown in FIG. 5, the board 20 has movable bearing parts 25, 2.
A mounting hole 27 is provided at a position slightly outside between the holes 6 and 6, and a half-cylindrical protrusion 28 is provided to surround this mounting hole 27 from the outside. This half-cylindrical protrusion 28 not only functions as a mating stopper part for the second stopper part 11F of the main movable piece 11 mentioned above, but also serves as a partner stopper part for the support protrusion 34 when fixing the middle front plate 30 to the base plate 20. It functions as a positioning guide member and also as a hidden part of the base of the movable pieces 11 and 12 after assembly.

Back side of middle part of board (a) Concave chamber In Figures 5, 6, and 7, concave chamber 35
, a peripheral wall 36 provided on the back surface of the substrate 20 so as to surround the window 21, and a rear surface 37 of the peripheral wall, more precisely, a rear surface member 70 that covers the rear end opening 37A.
(Fig. 12).

The circumferential wall 36 has an inner circumferential upper surface 36A and an inner circumferential lower surface 36B that are inclined in a tapered manner, and in particular, the inner circumferential lower surface 36B is inclined so as to face the space distribution means 62 in a forward-inclined state. A lower edge 38 remains on the rear surface 37 of the peripheral wall 36, and at the center of the lower edge,
A notch 38A is provided for leading out a lead wire (not shown) of the right number display 43 (FIG. 4) housed in the branch head 31 of the middle front plate 30 mentioned above. Partition walls 39 are erected on both sides of the inclined inner peripheral lower surface 36B extending from the lower side of the lower edge 38 to the lower side 21A of the window portion 21, and between each partition wall 39 and the lower edge 38 of the rear surface.
A prize-winning ball diverting port 39A is opened in the inner peripheral lower surface 36B between the ball and the ball. In other words, each partition wall 39 and the lower edge 38 of the rear surface
It also constitutes a diversion gutter for the partition wall 3.
9 also functions as a hidden part of the diversion port 39A.

(b) Diversion shelf branching means In FIGS. 4, 6, and 7, in the recessed chamber 35, one of the elements constituting the diversion shelf branching means together with the branching part head 31 of the middle front plate 30 is shown. Specifically, a flow divider shelf branching member 40 is disposed, and the recessed chamber 35 is divided into an "upper flow space" and a "lower distribution space" by the flow divider shelf branch member 40.

The flow divider shelf branching member 40 includes a central branch part 41 extending in the front-rear direction of the recessed chamber, and flow divider shelves 42 extending laterally on both sides thereof. The branch part 41 is
As can be seen from FIG. 8, the member has an inverted U-shaped cross section with an arcuate top surface 41A, and the inner cavity 41B is continuous with the notch 38A of the lower edge 38, and the inner cavity 41B is continuous with the notch 38A of the lower edge 38. It constitutes a continuous path through which a lead wire (not shown) is led out from the right number indicator 43 (FIG. 4) in the branch head 31. At the tip of the central branch 41, there is a right count indicator 43 housed within the branch head 31.
A small protrusion 44 (FIGS. 4 and 6) is provided in order to restrict the position of the branch head 31 from the rear.

The left and right flow dividing shelves 42 are located at a height that does not exceed the arcuate top surface 41A of the branching portion 41 (see Fig. 8), and the upper surface 42A is designed to ensure that winning balls flow backward. Top surface 4 of portion 41
1A, it is inclined so that it becomes lower toward the rear (see Fig. 4). Left and right diversion shelves 42
The length in the front-rear direction is from the starting end of the window portion 21 to this side of the partition wall 39. As can be seen from FIG. 6, the slope of the diverter shelf 42 allows the winning balls guided along the upper surface 42A of the diverter shelf 42 to be smoothly guided into the left and right diverters formed by the partition wall 39. It is designed to be thrown out.

The flow dividing shelf branching member 40 is attached only by supporting it in a cantilever near the window on the side surface of the peripheral wall 36 of the recessed chamber. That is, the locking portions 42 are formed of small flat projections provided at both ends of the flow dividing shelf 42.
B (Figs. 4 and 6) is simply inserted into the mating locking part 36C (Fig. 5), which is a groove formed on the side surface of the peripheral wall 36 of the concave chamber from the starting end of the window part. . Therefore, attachment of the flow divider shelf branching member 40 is extremely easy.

Due to the presence of the branching shelf branching member 40 in the recessed chamber 35, the following path for winning balls is formed. That is, the winning balls that enter the upper part of the flow space in the concave chamber 35 are sorted to the left and right by the top surface 41A of the branching part 41, or guided deep along the top surface 42A of the part 42, and then sent to the part of the parting gutter. It is guided by the barrel partition wall 39 and enters the diversion port 39A. Therefore, these winning balls are not guided to the special winning hole 19.

(c) Recessed chamber lower surface display section In FIGS.
(Fig. 5). That is, from the vicinity of the notch 38A of the lower edge 38 to the lower side 21 of the window portion 21.
The area that gradually becomes wider up to A (Figures 4 and 6) is made of a colored translucent member,
It can be illuminated with a lamp from the back side. This bottom display section 50 further includes A, B, C, D, which gradually increases in width from top to bottom.
It is divided into a plurality of small areas 51 indicated by E, and each small area 51 is colored alternately so that it can be individually illuminated from the back side.

As can be seen from FIGS. 7 and 8, on the back side of the substrate 20, below the inclined lower display section 50 made of a semi-transparent member, a partition wall 52 is provided along the boundary of each small area 51. Extending. As a result, the two outermost partition walls 52 are inclined downward, and their upper surfaces function as a guide surface 52A that guides the winning balls from the diversion port 39A. Moreover, between each partition wall 52, a small compartment 53 corresponding to each of the above-mentioned small regions 51 is formed.

In FIGS. 6 and 7, reference numeral 54 denotes a lower display board made of a printed circuit board carrying lower lamps 55 to be inserted into each of the compartments 53 in a number corresponding to the compartments. The lower display base 54 is provided between the substrate 20 and the drive source mounting plate 80. That is, it is fixed to a boss portion 58 provided at the rear end of the partition wall 52 with a screw 56 via a small hole 57 (see FIG. 9). Each small area 51 of the bottom display section 50 is illuminated by the bottom lamp 55 within this small compartment 53.

Lower part of the front side of the board In FIGS. 4 and 5, in order to form the above-mentioned three winning openings 18, 18, 19, in the lower front part of the board 20, the lower surface of the board 20 and the lower part of the window part 21 are shown. A U-shaped lower receiving frame 61 surrounding the side edge, a space distribution means 62 disposed approximately in the center of the space below the lower side 21A of the window portion 21 within the lower receiving frame, and covering the surface of the lower receiving frame 61. A lower front plate 60 is provided.

(a) Lower support frame The lower support frame 61 does not stand up at the same height from the surface of the board 20, but the U-shaped both ends of the lower support frame 61 have notches 61A (FIGS. 4 and 5).
It is slightly lower due to This is because the plate-shaped main portion 12A of the auxiliary movable piece 12 is attached to the lower receiving frame 61.
This is to enable rotational displacement without being hindered by. The lower receiving frame 61 has a prize opening 18,1.
In order to quickly and reliably discharge the winning balls that have entered the balls 8 and 19, an inclined guide portion 61B is provided at the bottom. In the pachinko machine of this example, as will be described later, when a special game mode occurs, when 10 pieces are won in the variable prize winning device (at this time, if you enter the special prize hole again), the special game mode is activated. If the winning ball enters the special winning hole slowly, the special winning detector 127
(Figure 20) Balls ejected from other winning ports without pressing the button will be sent to the count detector 128 first.
(Fig. 20), and if the count value is exactly the 10th, the special prize detector 12
The delay in pressing 7 causes the special game mode to end. Even if the player visually confirms that a prize has been won in the special prize opening, the above-mentioned problem may occur, causing trouble. Therefore, the inclined guide portion 61B plays a very important role in this respect.

(B) Space distribution means The space distribution means 62 forms the special winning opening 19 in the space inside the lower receiving frame 61, thereby simultaneously dividing the space into the normal winning opening 18 and the special winning opening 19. It is something. in particular,
The space distribution means 62 consists of two upright walls 63 erected on the bottom surface of the lower receiving frame 61, and an adjustment piece (special prize-winning assistance member) 64 superimposed and bonded to these upright walls. The reason why the space distribution means 62 is not integrally formed from the beginning in the molding stage of the board 20 is that the adjustment of the winning probability to the normal winning hole 18 and the special winning hole 19 is extremely delicate, and This is to avoid wasting the 20 molds and to allow subsequent adjustments to be made easily. For this purpose, the height of the upright wall 63 is formed in advance to be lower by the thickness of the adjustment piece 64, and when the adjustment piece 64 is superimposed on the upright wall 63, it reaches a predetermined height, in this example a window. It is determined to be in contact with the lower side 21A. For the same purpose, a separately formed strip 21B is attached to the lower side 21A of the window with an adhesive, as shown in FIG.

The space distribution means 62, that is, the winning ball guiding path for winning balls to the special winning opening 19 and the normal winning opening 18, is controlled by the lower surface display section 5, which is the bottom surface forming the concave chamber 35.
The reason why it is formed immediately below 0 is that it leads to the miniaturization of the entire variable prize winning device, and also allows the lower display section 5
This is because 0 can also be used as the upper surface of the passage, so there is no need to provide a separate guideway.

(c) Lower Front Plate In order to finely adjust the winning probability, a guide wall 60B made of small protrusions is also formed on the back surface of the lower front plate 60.

In this way, the adjustment piece 6 superimposed on the upright wall 63
4, a guide wall 60B of the lower front plate 60,
With the strip 21B on the lower side of the window 21A, the normal winning hole 18 and the special winning hole 19 are accurately provided with a fixed winning probability. These adjustment pieces 64, the guiding wall 60B of the lower front plate, and the strip 2
As for 1B, if you prepare several types with different wall thicknesses, protrusion amounts, or angles of inclination of the top surface, and select and use the one that best suits the model, you can use the same type. It can be made of any material. If the special winning assisting member is not separately provided, the entire variable winning device must be reconfigured until a probability suitable for the model is obtained, which will extremely increase the manufacturing cost of the device.

The upper middle part of the lower front plate 60 corresponding to the special winning hole 19 has a V-shaped notch in the center so that the player can see the winning balls that enter the special winning hole 19. Recessed window part 60
A is provided. In addition, approximately in the center of the front side of the lower front plate 60, there is a display section 6 indicating that it is a special winning opening at a location corresponding to the special winning opening 19.
0C is attached, so that the player can easily determine which is the special winning opening.

In addition, the three prize winning holes 18, 18, 19 are connected to the ball outlet passages 18A, 18A, 19A (Fig. 7) provided on the back surface of the board through openings provided on the bottom surface of the board 20 so as to be continuous with each other. Continuous. In this embodiment, ball lead-out passages 18A, 18A, and 19A are formed by ball lead-out portions 65 (FIG. 7) extending on the substrate surface so as to be continuous with the lower receiving frame 61 and the upright walls 63, 63.

Relationship with the front glass In FIG. 9, the upper front plate 24 of the variable prize winning device 10, the plate-shaped main portion 11B of the movable pieces 11 and 12,
12A and the lower front plate 60, when the variable prize winning device 10 is attached to the game board 1, the amount of protrusion of these components from the game board surface is the same as that between the front glass 66 of the pachinko machine and the board surface of the game board 1. It is configured so that it is smaller than the game space Z. That is, an attachment gap Z1 and a movable gap Z2 are left between the front glass 66, the upper front plate 24, and the main movable piece 11. This is to house the front element of the board device 20 of the variable prize winning device in the game space Z between the glass and the front of the game board, thereby preventing the glass from being damaged even if the metal frame is tightly tightened. . In this case, the movable piece 11 of the variable prize winning device attached to the game board is provided so that the front surface of the movable piece is on the upper side and lower than the surface of the front plates 24 and 60 (on the back side). Gap Z2
is formed between the inner surface of the glass and the inner surface of the glass. This is to prevent the movable piece 11 from coming into contact with the glass surface and causing malfunction, since the movable piece 11 has a certain degree of backlash in the front-rear direction. Z
3 indicates a sliding gap left between the back surface of the main movable piece 11 and the substrate 20 to ensure smooth movement of the main movable piece 11. Also, for the same purpose, the lower surface of the upper front plate 24, more precisely, the side surface 23B of the armor portion 23.
An abutting gap Y1 is provided between the lower end and the tip of the main movable piece 11. By providing these three gaps, the movable gap Z2, the sliding gap Z3, and the contact Y1, the movable piece 11 can operate smoothly and reliably without coming into contact with other members.
In order to attach the variable prize winning device 10 to the game board 1,
The mounting hole (winning device storage hole) 120 shown by dimension YO in FIG. derivation part 65, etc.)
A through gap Y2 is left between the mounting hole 120 and the mounting hole 120, so that the variable prize winning device 10 can be smoothly mounted on the game board 1. Also, board 2
Each device (drive source mounting plate 80, drive source 87, operating lever 90, partition wall 52 of the lower display section, board 54, movable levers 45, 4
The entire outer surface of the assembly 6) is configured to fit within the outer surface of the substrate 20 and not to exceed the outer periphery of the substrate. With this configuration, the variable prize winning device 10 can be easily and integrally attached to the game board 1 from the front side.

Flow path for winning balls Here, in connection with the opening and closing operations of the main movable pieces 11, 11, a flow path to the winning ball path in the recessed chamber 35;
The relationship with the flow path to the space distribution means 62 will be explained.

As can be seen from FIG. 2, the main movable pieces 11, 11 are in a substantially vertical state under the normal state where they are completely closed, and prevent the ball from hitting the ball.

When the main movable pieces 11, 11 are completely opened, the main movable pieces 11, 1
1 divides the space on the front side of the recessed chamber 35 into two, and completely closes the flow path to the space distribution means 62. That is, as can be seen from FIG. 3, the main movable pieces 11, 11 have the upper surfaces of the stopper portions 11D intersecting the front edge of the upper surface 42A of the diverter shelf, and the stopper portions 11D of the main movable pieces 11,
The inner end of 1D is located at a position slightly lower than the top surface of the branch head 31 of the middle front plate 30. In this fully open state, the ball that has entered the prize along the guide portion 11A hits the branch head 31, has its momentum lost, and is all guided to the upper flow space within the recessed chamber 35. As already mentioned, the winning balls that have entered the upper stream space are sorted to the left or right by the top surface 41A of the branching section 41, flow down to the back along the upper surface 42A of the diverter shelf 42, and enter the diverter gutter (section). wall 39), passes through the diversion port 39A (Fig. 6), and reaches the guide surface 52A of the partition wall.
(FIG. 8) and slips on the guide surface to fall into the winning ball gathering gutter 141 (FIG. 20). Therefore, these winning balls are not guided to the special winning hole 19.

A prize in the special prize opening 19 occurs when the main movable pieces 11, 11 are about to close or about to open, as described below.

In the process of the main movable pieces 11, 11 transitioning from the fully open state shown in FIG. 3 to the closed state, the main movable pieces 11,
11 is closed, the gap (FIG. 3) between the inner end of the stopper portion 11D and the branch head 31 becomes larger. Therefore, if a ball is placed on the guide portion 11A or the stopper portion 11D, the ball will move between the inner end of the stopper portion 11D and the branch head 31 due to the closing action of the main movable pieces 11, 11. and falls into the space distribution means 62. Since the space distribution means 62 divides the normal winning hole 18 and the special winning hole 19, the ball enters either of the winning holes. However, the winning process is not simple. For example, the guide wall 60B of the lower front plate 60
At this time, it bounces onto the lower inner surface 36B in the lower distribution space of the concave chamber 35, flows down on the lower inner surface 36B, and enters the normal prize opening 18 or the special prize opening 19.
to go into. The winning probability is comprehensively determined by the adjustment piece 64, the guide wall 60B, and the strip 21B.

Such a flow path to the space distribution means 62 is formed when the main movable pieces 11, 11 are about to open, that is, when there is still a gap large enough for the ball to pass between the inner end of the stopper part 11D and the branch part head 31. It also occurs when there is something left between.

In this way, when the movable piece 11 is in the fully open state, the winning balls are placed on the flow dividing shelf and are guided to the rear, and only when the movable piece 11 shifts to the closed state or the open state, it is guided to the space distribution means 62. By doing so,
It is possible to make the player play an interesting game in which it is determined whether the player will enter the special winning hole 19 or not.

Board Design Section In FIGS. 5 and 17, the outer periphery of the board 20 is formed with a peripheral edge surface 20B that slopes downward from the board surface 20A toward the outside. In addition, on the outer periphery of the board, an appropriate number of fastening parts 2 are placed at appropriate intervals.
A fastening hole 20D is provided in the fastening part.
is provided. In this case, the fastening portion 20C is on the same level as the substrate surface 20A and protrudes in a raised shape into the area of the peripheral surface 20B. In other words, only the fastening portion 20C avoids being sloped like the peripheral surface 20B for the purpose of increasing the mounting strength.

On the other hand, a suitable design surface 20 is provided on the substrate surface 20A.
E is formed. This design surface 20E is the first
As shown in FIG. 7A, an upright portion 20F linearly protrudes from the substrate surface 20A, which is the thickness surface of the substrate 20.
and a colored material 20G coated or pasted with paint, stickers, etc. within the area surrounded by the upright portion 20F. In this way, the substrate surface 20
A design surface 20 is provided by providing a plurality of standing portions 20F on A.
The way to configure E is as shown in Figure 17B.
A plurality of grooves are provided on the substrate surface 20A to create a design surface 2.
Compared to the conventional method of setting 0E, the strength of the substrate 20 can be dramatically increased.

Middle part of back surface of substrate Next, the configuration behind the recessed chamber 35 will be described with reference to FIGS. 11 to 13.

(a) Rear member A transparent case 70 that is open to the rear and serves as a rear member.
is screwed to a boss portion 37B (FIG. 7) provided at the rear open end 37A of the rear surface 37 of the peripheral wall. The front surface of the transparent case 70 completely covers the rear open end 37A of the rear surface 37 of the peripheral wall, thereby forming a complete recessed chamber 35 when viewed from the player. Inside the rear member, that is, the transparent case 70, as a component of the background display device 77, there is built-in a background carrier 73 made of an endless film wound around two vertically arranged rolls 71 and 72 (FIG. 8). ing. Axis 71A of both rolls 71, 72,
72A is the rear open end 70A of the transparent case 70
It is rotatably supported by a bearing 74 consisting of a groove provided from the rear. Of these, the shaft 71A of one of the rolls 71 extends downward and has a gear 75B at its lower end. This gear 75B
is a gear 75A provided on the output shaft of the motor 76.
(FIG. 20), and thus the roll 71 functions as a drive roll. The other roll 72 is rotatably supported at the end,
Acts as a subordinate role.

The components 71 to 76 described above constitute a background display device 77 as a whole, and the motor 7
6 rotates the drive roll 71, the background carrier 73 is moved and displayed brightly on the inner surface of the recessed chamber 35.

(B) Support Plate A support plate 78 is attached to the rear open end 70A of the transparent case 70, so that the transparent case 70 can support the shafts 71A, 72 of both rolls 71, 72.
A is covered to prevent it from separating from the bearing 74. In this embodiment, the support plate 78 is screwed to the boss portion 70B of the rear open end 70A of the transparent case through its small hole 78A. Support plate 78
A lamp mounting part 78B is provided at the lower part of the background carrier 73 for mounting an illumination lamp 79 to be placed in the gap between the forward moving part and the backward moving part of the background carrier 73 made of the endless film. A binding piece 78C is provided on the back side of the support plate 78 for bundling the lead wire 79A of the transparent lamp 79 and the lead wire 55A (FIG. 7) of the lower lamp 55 together and guiding them from below to above the support plate 78. be. Further, on the back surface of the support plate 78, these lead wires 79A, 5
In order to form a space for passing 5A, and further to form a space to enhance the heat dissipation effect of the metal drive source mounting plate 80, the four boss portions 78 are
D is provided protrudingly.

(c) Drive source mounting plate The boss portion 78D on the back side of the support plate 78 has a first
A drive source mounting plate 80 carrying an electromagnetic solenoid 78 serving as a drive source is attached.

The drive source mounting plate 80 has a flat base 81 facing the support plate 78, wing parts 82 bent backward in a U-shape from both ends of the base 81 to increase the heat dissipation area, and a wing part 82 below the base 81. It has two extending legs 83. The drive source mounting plate 80 is fitted with screws 86 through fixing holes 81A provided in the base 81.
It is attached to the boss portion 78D of the support plate 78. At the lower ends of the two leg parts 83, a spring hook part 83A for the return spring 84 is formed by respectively folding back. A tongue stand 85 is formed by folding back at the center of the lower end of the base 81, that is, at the center between the bases of the two legs 83, 83. This tongue 85 functions as an auxiliary receiving surface for the operating lever, as will be described later.

(d) First driving source Two electromagnetic solenoids 87 as the first driving source
is a U-shaped yoke 87A and a coil body 87.
B, and a plunger shaft 88.
Both electromagnetic solenoids 87 are connected to the drive source mounting plate 8.
Between the wing parts 82 and 82 of the base part 81, they are arranged parallel to each other on the back surface of the base part 81 so that each movement is uniform, and are attached from the front side of the base part 81 with screws (not shown). be. in this case,
The individual electromagnetic solenoids 87 are mounted vertically with their respective plunger shafts 88 depending downwardly. As can be clearly seen from FIG. 13, at the tip of each plunger shaft 88, a single groove 89 is provided from the end face side, and a ring-shaped stopper 89 is provided in front of the groove 89.
8A is fixed. Around each plunger shaft 88, a return shaft spring 8 is installed between the stopper 88A and the yoke 87A.
8B is wound. This shaft spring 88B
Normally, the plunger shaft 88 is biased in one direction, that is, downwardly, and the plunger shaft 88 is
8 is a conical coil spring in which the coils do not overlap but are substantially parallel when attracted, and the plunger shaft 88 is fitted so that the small diameter side of the spring is located on the stopper 88A side.

(E) Actuation Lever At the tip of each of the plunger shafts 88, a part of the plunger shaft 88 is fitted into a groove 89, and an actuation lever 90 is independently fixed thereto.

The two left and right actuating levers 90 are made of a symmetrical plate-shaped synthetic resin, and extend outward from the center line of each plunger shaft 88. A notch 90A is formed in the inner upper part of each operating lever 90 so as not to inhibit the movement of the plunger shaft 88.

As can be clearly seen from FIG. 13, each operating lever 90 has a shaft storage part 91 for securely mounting the shaft 88 of the electromagnetic solenoid, and a shaft storage part 91 for holding the operating lever parallel to the drive source mounting plate 80. An appropriate number of operating lever upright portions 92 extend toward the flat base 81 of the drive source mounting plate 80 until they come into sliding contact with the drive source mounting plate 80 or just before sliding contact, and the pins 48 and 49 of the movable lever The first one has a shape and size that can always maintain the fitted state so that it does not come off and can operate the movable lever.
It has an engagement hole 93, a second engagement hole 94 (operating lever fitting part), and a counterpart spring hook part 95 for the spring hook part 83A. Both spring hooks 8
A return spring 84 is latched between 3A and 95. In order to facilitate the latching and unlatching of the return spring 84, a spring latching portion 95 on the operating lever 90 side is provided.
is shaped like a hook.

In this embodiment, the shaft storage section 91 has two
It consists of two constituent parts. The first component is a rectangular recess 91A having a width and length corresponding to the groove 89 of the shaft 88, and the recess is provided on both the front and back sides of the actuating lever 90. In this case, the wall thickness remaining between the depressions 91A and 91A on the front and back sides is
It is determined to fit within the slit width of the groove 89. The second component is a positioning holding part 91B that is a semicircular through hole that passes through one half of the shaft 88 divided by the groove 89.
and is provided at the upper end of the operating lever 90. Then, in the shaft storage section 91,
After the actuating lever 90 is fitted into the groove 89 of the shaft 88, a screw 96 is passed through both to fix them to each other. However, the shaft storage portion 91 is not limited to the form of this embodiment, and may be configured with a cylindrical portion,
Alternatively, it may be constructed of a plate-like portion having a U-shaped notch.

Providing the shaft storage portion 91 is important for ensuring the connection between the actuating lever 90 and the shaft 88 of the electromagnetic solenoid and ensuring smooth and durable movement of the movable piece. Further, providing the shaft housing portion 91 of a type in which the thickness of the actuating lever 90 is accommodated within the slotted groove 89 satisfies this need and is advantageous in that the depth dimension of the drive unit can be reduced. .

In this embodiment, the actuating lever standing portion 92 is
Two are provided on both sides of the shaft storage section 91,
As shown in FIG. 13, its tip surface is floating with a slight gap d relative to the flat base 81 of the drive source mounting plate 80. This achieves the purpose of holding the operating lever 90 parallel to the drive source mounting plate 80 when the operating lever 90 is tilted beyond this gap, and also extends the normal usage period until such a situation occurs. Among these, the purpose is to eliminate contact friction between the operating lever 90 and the drive source mounting plate 80, lighten the load on the drive source, and ensure smooth movement of the operating lever 90.

The reason why the left and right movable wings 11 and 12 are driven independently is that when a ball is caught in either the left or right main movable wing 11 during a pachinko game, the main movable wing 11 on the other side is driven independently. This is to ensure that it closes quickly.

(F) Engagement with the movable piece lever The electromagnetic solenoid 87 with the operating lever 90 integrally fixed to the plunger shaft 88 in advance is attached to the drive source mounting plate 80, and then this assembly is attached to the support plate 78. mounted on. In this case, the pins 48 and 49 of the main movable lever can be moved to the first position provided on the operating lever 90 without any special positioning operation by the operator.
It can be inserted into the engagement hole 93 and the second engagement hole 94 correctly. This is because the movable levers 45 and 46 are disposed on the outside of the operating perpendicular to the plunger shaft 88 and inward from the plunger shaft 88 . Further, as already mentioned, the mounting position of the main movable piece lever 45 with respect to the main movable shaft 13 is in a positional relationship that gives the main movable piece 11 a rotational habit in the direction of the closed position due to its own weight. This is because the main movable piece lever 45 is easily stabilized in the diagonally downward inward position (the closed position of the main movable piece 11). In addition, the auxiliary movable lever 4
6 also extends in the opposite direction to the direction in which the main movable lever 45 extends and becomes stable. When attaching the drive source mounting plate 80 to the support plate 78, the lead wires (not shown) from the right number display 43 and the lead wires 55A and 79A from the lower lamp 55 and the illumination lamp 79 are attached to the drive source. It is guided from bottom to top through the gap between the mounting plate 80 and the support plate 78, and is supported by the support plate 78 by the binding piece 78C along the way.

FIGS. 14A and 14B show the engaging holes 93, 94 and pins 48, 49 when the electromagnetic solenoid 87 is not conducting (the main movable piece is in the first state) and when it is energized (the main movable piece is in the second state). This figure shows the engagement positional relationship with. The first engagement hole 93 is formed to be horizontally long so that when the operating lever 90 pushes up the pin 48 of the main movable lever, the pin 48 can escape laterally. Further, the second engagement hole 94 is opened to the pin 48 of the main movable lever by the movement of the operating lever 90.
In order to be activated later than the movement of the main movable piece 11, the main movable piece 11 is provided so as to have a large opening below the pin 49 when viewed in the closed state shown in FIG. 14A. In the first state, the main movable piece lever 45 is engaged with the operating lever 90 at a position lower than the movable shaft 13, and when it changes to the second state,
This fitting portion is configured to be above the movable shaft 13. With this configuration, the linear movement of the drive source is controlled by the operating lever 90 and the movable piece lever 45, and the rotational movement (≒
90 degrees) with minimal force and movement. Also, the return from the second state to the first state is performed by the plunger shaft 8 of the drive source.
Since this is performed using the potential energy of 8 and the weight of each member, such a configuration can minimize energy loss.

As described above, the drive source mounting plate 80 is attached to the end without any special positioning operation by the operator.
The fact that the electromagnetic solenoid 87 and the actuating lever 90 can be correctly installed smoothly and quickly simply by attaching the solenoid to the support plate 78 brings an extremely large advantage in the assembly process. Furthermore, the electromagnetic source mounting plate 80 is important not only as an element for forming such a single unit, but also for dissipating heat generated in the electromagnetic solenoid 87 with high efficiency.
The existence of the space between the wing portion 82 and the base portion 81 and the support plate 78 is extremely effective not only as a passage for the lead wire but also in terms of heat dissipation.

(g) Actuation lever auxiliary receiving surface Fig. 15A shows the relationship between the main movable piece 11 in the closed state and the tongue 85, which is the actuation lever auxiliary receiving surface, and Fig. 15B shows the relationship between the main movable piece 11 in the closed state and the tongue 85 as the operating lever auxiliary receiving surface. Main movable piece 11
The relationship between the tongue 85 and the tongue 85 is shown.

In the closed state shown in FIG. 15A, as described above, the stopper portion 11D of the main movable piece 11 is in contact with the rotation base 12C of the auxiliary movable piece 12, and in this state, the main movable Piece 11 is stable. This is because the operating lever 90 receives a downward force due to its own weight and the weight of the plunger shaft 88, is pushed down by the shaft spring 88B, and is pulled downward by the return spring 84. This is because the main movable piece 11, which is engaged with the operating lever 90 via the pin 48, is given a rotational force in the counterclockwise direction in FIG. 15A. At this time, the auxiliary movable piece 12 is located between the position where the lower surface of the stopper part 12B abuts the upper outer side of the lower receiving frame 61 and the position where the pin 49 engages with the upper edge of the second engagement hole 94. Although a slight rocking movement is possible, the plate-like main portion 12A is normally in the state shown in FIG. 15A due to the force that tends to move it downward.

In the closed state shown in FIG. 15A, the tongue 85, which is the auxiliary receiving surface of the operating lever, has a slight gap (first gap) 97 of about 0.5 mm to 1 mm between the tongue 85 and the lower surface of each of the left and right operating levers 90. It is positioned so that it is formed. Therefore, the width of the tongue 85 is longer than the width between the left and right operating levers 90, 90. Providing the tongue 85 in this manner provides the following benefits.

First, it is possible to prevent the plunger shaft 88 of the electromagnetic solenoid 87 from coming off during assembly. That is, the electromagnetic solenoid 87 which is the first driving source
The operating lever 90 is attached to the plunger shaft 88.
Although the electromagnetic solenoid 87 is managed as one component in the stored state, the electromagnetic solenoid 87 is assembled with the plunger shaft 88 facing downward, and the variable prize winning device 10 is also installed in this state. It will be done. Therefore, if there is no tongue 85, the plunger shaft 88 will fall off from the coil body 87B during assembly, requiring time and effort for assembly. However, if the tongue 85 is provided, the actuating lever 90, which is integrally fixed to the plunger shaft 88, can be placed on the tongue 85 to prevent it from falling off, and the yoke 87A of the electromagnetic solenoid 87 can be attached to the drive source. It can be attached to the plate 80, and its posture after attachment can be maintained in the state shown in FIG. 11. Therefore, assembly work is made extremely easy.

Second, even if the stopper position of the main movable piece 11 goes out of alignment due to wear after a certain period of use after the variable winning device is assembled, the so-called wobbling of the main movable piece 11 in the closed position can be kept within the permissible limit. I can pay it. Specifically, if there is no tongue 85, the more the main movable piece 11 wears, the more the closed position of the main movable piece 11 deviates from the predetermined stop position, causing wobbling and becoming unstable, and eventually the game becomes unstable. slightly affect the condition. However, if the tongue 85 is provided with the first gap 97 left as described above, even if the stop position shifts, it will only occur until the operating lever 90 comes into contact with the tongue 85.
After that, the stopper portion 11D of the main movable piece 11
The tongue 85 acts as an auxiliary stopper for the main stopper constituted by the rotation base 12C of the auxiliary movable piece 12, and keeps the so-called wobbling of the main movable piece 11 within an allowable limit. The tongue 85 is made of metal,
Main and auxiliary movable pieces 1 made of ordinary synthetic resin
Since it has higher wear resistance than No. 1 and No. 12, the life of the variable prize winning device can be extended. However, even if the tongue 85 is not made of metal, the closed position of the main movable piece 11 is regulated by the cooperation of the main stopper and the auxiliary stopper.
The lifespan of the variable prize winning device can be extended compared to a structure without such structure.

As shown in FIG. 15B, the main movable piece 11 is
Rotating base 11C on the lower surface of the flat guide portion 11A
The part closest to the cylindrical part comes into contact with the half-cylindrical protrusion 28 to be in the open position. At this time, the operating lever 90
is lifted to the position shown in FIG. 15B, and a second gap 98, which is the stroke margin of the plunger, is left above the stop ring 88A of the plunger shaft 88. This second void 9
8 is the stop ring 88A in FIG. 15B.
Although this is shown as a gap between the main movable piece 11 and the yoke 87A, to be more precise, the main movable piece 11 is
8 and the upper limit position of the stopper ring 88A when the plunger shaft 88 is pulled upward to the maximum extent.

By forming such a second gap 98, the main movable piece 11 comes into contact with the protrusion 28 and functions reliably as a main stopper, and the force of the electromagnetic solenoid 87 that tries to pull the main movable piece 11 upward is also applied to the main movable piece 11. The movable piece 11 comes to be pressed against the protrusion 28. Therefore, the open position is accurately determined. Further, even if the open position shifts due to wear, the plunger shaft 88 can be pulled extra by the width of the second gap 98, so that the open position does not fluctuate.

Special Display Device In FIGS. 16, 18, and 19, the variable prize winning device 10 is equipped with a special display device 100 that is different from the movable pieces 11 and 12.

This special display device 100 will be explained mainly with reference to FIG. 18. As shown in FIG.

It is hidden behind the upper front plate 24, as shown by the dotted line in the figure. However, when the electromagnetic solenoid 109, which is the second driving source, is energized, the second control lever 105 is attracted, and the first control lever 102 rotates counterclockwise in FIG. 18 about the shaft 103. , the special display member 101 appears in the recessed chamber 35 as shown by the solid line in FIG. In order not to impede the movement of the arm 102A of the first control lever 102, the recess 35 is provided with a recess 35B (FIG. 19) whose ceiling is partially elevated. The rotation range of the first control lever 102 is restricted by
Stopper 113 consisting of a protrusion provided in recess 35B
The upper limit is determined by the arm 102A coming into contact with the opening 35A (see FIG. 7), and the lower limit is determined by the arm 102A coming into contact with the lower edge of the opening 35A on the side surface of the concave chamber (see FIG. 7).

In this embodiment, the special display member 101 is modeled after a horse racing horse, and is configured to descend onto the middle front plate 30, which is modeled after the torso of a horse described above. In addition, special display member 101
is pivoted with a swinging piece 114 that resembles the "whip" that Zjodsky holds in his hand.

Reference numeral 120 indicates a winning device storage hole provided in the center of the game board 1. In the center of the game board 1, there are openings 121 for the top prize opening 16 and side prize opening 17 on the top of the variable winning device, and on both sides, there are general winning devices 4A,
Below the winning device holes 122A and 122B of 4B, winning device holes 123 and 124 are provided which are continuous with the winning openings of the specific winning devices 8 and 9. Winning device hole 12 that is continuous with the specific winning hole located below
3,124, the winning device holes 123 on both sides are equipped with a first operation detector (first operation detection switch SW1) 1 that detects a winning ball entering the first specific winning hole 8.
25, and the center winning device hole 124 has a second
A second operation detector (second operation detection switch SW2) 126 that detects a winning ball entering the specific winning hole 9 is attached. On the other hand, on the back of the game board, there is an upper winning ball guide plate 130 having an opening 131 along the winning device storage hole 120, and a lower winning ball guide plate 1.
40 and a side winning ball guide plate 137 are fixed.

The variable winning device 10 has a winning device storage hole 120 and an opening 131 of the upper winning ball guide plate 130.
It is attached from the front side of the game board 1 through the board. In this case, the components of the rear block of the variable prize winning device 10, namely, the movable levers 45, 46, the transparent case 70, the support plate 78, the drive source mounting plate 80,
As is clear from the above description, the actuating lever 90 is mounted compactly within the width of the base plate 20 as a whole. Therefore, the rear block of the variable winning device 10 can be smoothly passed through the winning device storage hole 120.

(B) Upper Winning Ball Guide Board The upper winning ball guide plate 130 includes an upper winning ball guide gutter 132 that is formed in the shape of a roof as a whole and guides winning balls from the above-mentioned top winning hole 16 to one side;
A lower winning ball guide trough 133 is provided along the upper winning ball guiding trough to guide the winning balls from the left and right side winning holes 17, 17 separately to the left and right. The upper winning ball guide gutter 132 and the lower winning ball guiding gutter 133 are made up of standing walls raised from the upper winning ball guide plate 130 extending along the back surface of the game board, and in particular, the lower winning ball guiding gutter 133 is located below the upper winning ball guide gutter 132. It also serves to protect the variable winning device 10 from being hit by winning balls. Also.
The upper winning ball guide plate 130 has an inclined plate portion 13 on the inside of the lower winning ball guide gutter 133 for mounting the electromagnetic solenoid 109 serving as the second drive source.
It has 4. By providing the inclined plate portion 134 in an inclined manner as shown in FIG. 20, a downward force due to its own weight acts on the plunger shaft 110, and the return spring of the second drive source can be omitted. The upper winning ball guide plate 130 has a projection 29 extending on the back surface of the board 20 of the variable winning device.
A small hole 29A as a counterpart positioning part is provided at a position corresponding to the positioning part consisting of.
Therefore, the mounting position of the variable winning device 10 with respect to the upper winning ball guide plate 130 can be accurately determined.

(B) Lower Winning Ball Guide Board The lower winning ball guide board 140 located below the upper winning ball guide board 130 collects the winning balls that have entered the concave chamber in one place. ) and a box-shaped winning ball gathering gutter (count guide gutter) 141 with an open top surface.
The lower winning ball guide board 140 is the winning ball collection gutter 14
1, the upper edge 143 of the flange portion 142 on both sides of the
It is arranged so as to overlap the lower edge 135 of the upper winning ball guide plate 130. Reference numeral 136 indicates a positioning engagement portion consisting of a small protrusion and a small hole provided for positioning during this superposition. This engaging portion 136 allows the position of the winning ball gathering gutter 141 to be accurately determined with respect to the upper winning guide plate 130. As a result, the variable winning device 10 has the above-mentioned positioning parts 29 and 2.
9A and this positioning engagement part 136, it is possible to attach it to an accurate position with respect to the winning ball gathering gutter 141. By providing the positioning part 29 in the variable winning device itself in this way, the winning ball gathering gutter 141 between the variable winning device 10 and the
and can be easily installed in the appropriate position. This increases the efficiency of installation work and allows for the same quality in terms of pachinko machine functions. In addition, as described above, each ball outlet of the variable winning device (from the diversion port 39A, the normal winning port 18, and the special winning port 19) and the inlet of the winning ball collection gutter,
It becomes continuous as desired.

The box-shaped winning ball collecting gutter 141 has a discharge port 14 located at the center of its lower surface, that is, at a position offset from the first operation detector 125 and the second operation detector 126.
4 is provided. More specifically, it is provided between the first actuation detector 125 and the second actuation detector 126 located on the left side when viewed from the player. This is because pachinko machines usually have a ball disposal device on the right side of the game board 1 as seen from the player, which takes out winning balls one by one and discharges a predetermined number of winning balls. It is something. That is, the discharge port 144 is disposed on the left side far from the ball processing device, and a large number of winning balls generated in the special game state are smoothly fed into the ball processing device without clogging or forming a stone wall. This is to enable processing.

The bottom surface of the winning ball collection gutter 141 is this outlet 1.
Inclined surfaces 14 located on the left and right with 44 as the center
It is divided into 5,146 parts. These two slopes 1
45 and 146, the height position of the lower end of the discharge port 144 is made so that one inclined surface 145 is lower than the other inclined surface 146 by a step Y (FIG. 20). This is a consideration to prevent balls from clogging at the release port 144 when a large number of batted balls win prizes in a short period of time when the variable winning device 10 is in the open state. .

The side winning ball guide plate 137 has a side winning ball guide gutter 138 that separately guides the winning balls from the left and right winning device holes 122 downward, and especially the 20th winning ball guide plate 137
The side winning ball guide plate 137 on the right side in the figure further includes:
It also has a side winning ball guide gutter 139 that guides the winning balls from the upper winning ball guide gutter 132 further downward. The left and right side winning ball guide troughs 138 are both configured to guide the winning balls from the lower winning ball guide trough 133 further downward.

A special winning detector (special winning switch SW3) 127 for detecting winning balls from the special winning opening 19 of the variable winning device 10 is provided in the middle of the box-shaped winning ball collection gutter 141. To be more specific, the box-shaped winning ball gathering gutter 141 has a cutout below the position corresponding to the ball outlet passage 19A (FIG. 7), and a special winning detector 127 consisting of a micro switch is installed in the cutout. The ball passage section is inserted. The special prize detector 127 is fixed to the prize ball collecting gutter 141 by using an auxiliary piece 147 whose one side is engaged with the side surface of the special prize detector 127.
This is done by fixing screws to the winning ball collecting gutter 141.

Furthermore, the outlet 1 of the box-shaped winning ball collection gutter 141
A count detector (count switch SW4) 128 is attached to the ball path continuous with 44 in the same manner as the special winning detector 127, that is, via another auxiliary piece 147. Outside the game area of the game board, there is a number display 129 (see Figure 1) consisting of a 7-segment LED to display the winning balls counted by the count detector 128.
is provided.

In this way, the winning ball collection gutter is detected by the special winning ball detector 1.
27, and if the winning balls that passed through the special winning detector are also counted, the winning balls that pass through the special winning detector will be more likely to win in the special game state than when the winning balls are not counted. , for example, 10, can be counted approximately accurately. The reason why the word "approximately" is used here is that there is a time difference between when the winning balls are won by the variable winning device and when the winning balls are counted by the count detector 128. A ball collecting board 148 is attached to the back of the game board 1, as shown by the broken line in FIG.
0, upper and lower both winning ball guide channels 132, 133,
The winning ball collection gutter 141 is covered from the rear. The ball collecting plate 148 that covers the rear surface of the winning ball collecting gutter, etc.
Special prize detector 127, operation detector 125,
Notches 148A are provided in the vicinity of 126, etc. for passing electrical connection lines therethrough, and the electrical connection lines are passed through these notches 148A in a concentrated manner.
Connected to a predetermined connection.

As mentioned above, each ball outlet of the variable winning device (divergent opening 39A, normal winning opening 18 and special winning opening 1)
9) with the inlet of the winning ball collection gutter, and a configuration that also counts the winning balls that have passed through the special winning detector 127.
The lower surface of 41 is made uneven at the discharge port 144, and the discharge port 144 of 141 of the winning ball collection gutter is opened near the operation detector 124 as described above, and a guide shelf that becomes the bottom of the ball collection plate 148 is constructed. 149 is an important technology in the pachinko machine of this embodiment. This is because the pachinko machine of this example has operation detectors 125 and 12 provided below the game board, as will be described in detail later.
6, movable piece 11 moves once,
Or, if the ball is rotated about two times and at this time, the ball that flies into the variable winning device 10 accidentally enters the special winning hole 19, the movable piece 11 is rotated several times in succession (for example, 18 times). Moreover, by making it possible to repeat the cycle a plurality of times (e.g., 8 times), a special profit state is generated in which the possibility of winning a prize with a ball hit into the variable prize winning device 10 is increased. Therefore, it is necessary to quickly and reliably process a large number of winning balls that are generated at once. In addition, in the above-mentioned variable prize winning device, the movable member is rotated more than ten times in succession, and this is repeated multiple times when the continuation condition is met, so it gives excessive profits to the player. Sometimes. Therefore, in order to suppress the maximum profit to some extent, it is necessary to limit the number of balls that can win a prize during one continuous operation to, for example, 10. In order to do this, it is necessary to accurately count the winning balls of the variable winning device and to detect the winning balls that enter the special winning hole of the variable winning device.

Modified embodiment of the back side of the game board (a) Interlocking unit FIG. 21 shows an interlocking unit 150 in which the upper winning ball guide plate 130 and the lower winning ball guiding plate 140 are not separated into the upper winning ball guide plate 130 and the lower winning ball guiding plate 140, but are integrally formed.
An example is shown below. That is, this interlocking unit 15
0 includes an upper winning ball guide gutter 132 that guides winning balls from the top winning hole 16 to one side, a lower winning ball guide gutter 133 that guides winning balls from the left and right side winning holes 17 separately to the left and right, and Prize winning device hole 12
A side winning ball guide gutter 138 that separately guides winning balls from 2A downward, and a winning ball collecting gutter 141 that separates winning balls that have entered the concave chamber from winning balls in other gutter and collects them separately below. have integrally.
The type of gutter to be integrated into an interlocking unit is determined in relation to the game content of the pachinko machine. In any case, by forming each of these interlocking gutters into a unit, the number of parts to be managed is reduced compared to the case where the gutters are installed individually, and the number of assembly steps can be reduced.

(b) Positioning of the interlocking unit Furthermore, this interlocking unit 150 has flange portions 151 for attachment to the game board 1 at appropriate locations around the periphery, and the flange portions are attached to the fixing members 152 made of U-shaped nails to attach the flange portions to the game board 1. It is installed on panel 1. The interlocking unit 150 also includes a game board 1.
Positioning portions 153 are provided at an appropriate number of locations to facilitate and accurately position the device when attached to the device. In this embodiment, L-shaped protrusions 153A are hung from the lower ends of the left and right sides of the interlocking unit 150, and when installed, the L-shaped parts are attached to the general prize winning devices 4 on both the left and right sleeves.
It is configured to face the corner portions of B and 4B, and its position is restricted. As a result, interlocking unit 1
50 on the back of the game board, positioning part 1
53 (at least two places in this example) into the positions of the general winning device 4B, the position of the interlocking unit 150 with respect to the game board 1 can be adjusted.

(C) Attaching the Detector Unlike the example shown in FIG. 20, the winning ball gathering gutter 141 has a recess 154 instead of a cutout in the middle, and the special winning ball detector 127 is installed in the recess.
(SW3) is stored. In addition, a special guide gutter 155 is provided in the winning ball collection gutter 141 to guide the winning balls from the special winning hole 19 to the special winning detector 127, distinguishing them from the winning balls coming from the normal winning hole 18. .

As can be clearly seen from FIG. 22, this special prize detector 127 has a body portion 127B held between two holding members 156 protruding from the bottom of the recess 154, and a ball passage portion 127A at the tip.
is aligned with the lower end opening of the special guide trough 155. Regarding this alignment, the lateral positioning of the special win detector 127 is such that the tip position of the special win detector 127 is regulated by the side wall of the recess 154, and the rear end position of the special win detector 127 is provided on the bottom surface of the recess 154. This is done by being restricted by an upright portion 157 consisting of a protrusion. two clamping members 15
6 has some flexibility in the clamping direction, and is reliably held so as not to come off due to this flexibility and the claw 156A provided at the tip. However, due to their flexibility, the two clamping members 156 can be expanded in the direction shown by the arrows to move away from each other by applying an external force, so the special prize detector 127 can be easily removed. .

155A is a guide surface formed inside the special guide gutter 155, which draws a gentle arc toward the inlet of the special winning prize detector 127. Due to the presence of such guide surface 155A, the special guide gutter 1
55 can smoothly flow into the ball passage section 127A of the special winning detector 127, preventing the detector from malfunctioning due to the impact of the balls, reducing wear on the detector, and improving its durability. It has the effect of increasing

The installation of the count detector 128 is the same as that of the special prize detector 127, and the recess 1 provided at the lower end of the outlet 144 of the winning ball collection gutter 141 is installed.
A clamping member 156 is provided within the interlocking unit 58, and is detachably attached to the interlocking unit 150 from the rear. In this way, the special prize detector 127
and the count detector 128 in the interlocking unit 1
By detachably attaching the device from the rear of the device 50, installation, maintenance and inspection, and replacement in the event of a failure can be easily performed.

(d) Processing of electrical connection lines Furthermore, this interlocking unit 150 carries a connection conversion member 160 as a terminal for a large number of electrical connection lines routed to the back side of the game board. In this embodiment, the surrounding flange portion 151
A boss is erected on the supporting surface 159 formed by extending the base plate 161 of the connection exchange member 160.
is fixed with screws. This board 161 includes a plurality of input connectors (male connectors) 162,
It has one or more output connectors (male connectors) 163, into which mating connectors (female connectors) 162A and 163A provided at the ends of electrical connection wires 164 and 165 are respectively inserted. It will be done. The electrical connection line 165 from the output connector 163 is connected to a control device (not shown) via, for example, a female connector 165A. Providing such a connection conversion member 160 in the interlocking unit 150 also makes the installation of the connection conversion member 160 much easier than in the case where the connection conversion member 160 is installed before or after the interlocking unit 150 is installed. It means to get. Further, as a result of the connection conversion member 160 being provided in the interlocking unit 150, the processing of connection lines for each of the detectors 125 to 128, the drive source 87, etc. can be simplified.

Although not shown in FIG. 21, the upper surface of the interlocking unit 150, which serves as a route for electrical connection lines, has appropriate locations, for example, electrical connections from each of the detectors 125 to 128 disposed on the game board. line 164A
In the middle of the path leading to the connection conversion member 160,
As shown in FIG. 23, a binder 166 is provided. This binder 166 is connected to the interlocking unit 15.
Two opposing hooks 1 protruding from the top surface of 0
Consisting of 67,168, on the top of both hooks,
Guide surface 16 inclined toward the hook of the other side
7A and 168A are formed. Due to the action of these guide surfaces 167A and 168A, the connecting wire 164A can be smoothly stored in the binder 166 by pushing the connecting wire 164A from the outside in the direction of arrow A. However, after insertion, it is easy to pull it in the direction of arrow B. It will not come off. Therefore, wiring processing during assembly becomes extremely easy. Incidentally, such a binder can be formed integrally when the interlocking unit 150 is molded.

The winning balls from the normal winning hole 18 of the variable winning device 10 are divided into left and right sides of the special winning detector 127, as in the case of FIG. All merged, the count was 140 and the discharge port was 144.
are collected, and the total is counted by this count detector 128.

Control device FIG. 33 is a circuit diagram of the control device.

To briefly explain the electrical elements already mentioned,
SW1 is the first operation detection switch (first operation detector 125) attached to the specific winning opening 8, SW2 is the second operation detection switch (second operation detector 126) attached to the specific winning opening 9, and SW3 is the second operation detection switch (second operation detector 126) attached to the specific winning opening 9. A special prize switch (special prize detector 127) attached to the special prize opening 19 on the back side of the game board, SW4 is a counter for counting winning balls attached to the outlet 144 of the winning ball collection gutter 141 on the back side of the game board. switch (count detector 128). SOL1 is a first solenoid (first drive source 87) for driving the left and right movable pieces 11, and SOL2 is a second solenoid (second drive source 10) for driving the special display member 101 up and down.
9), M is a motor (motor 76) which is a driving source of the background display device 77. LA to LE indicate the lower lamps 55 belonging to the small areas 51 of A to E of the lower display section 50. 43 is a right number display consisting of a 7-segment LED provided on the middle front plate 30, 1
Reference numeral 29 denotes a number display (see FIG. 1) consisting of a 7-segment LED provided outside the game area of the game board 1.

Reference numeral 201 is a reference time generating section, which, although not shown, includes a crystal oscillating section that oscillates at a frequency of 32768 Hz;
It includes a multistage frequency divider for this oscillation clock and a logic circuit connected to the frequency divider, and generates three types of time signals S1, S2, and S3 necessary for operation. The first time signal S1 obtained through the logic circuit has a repetition period of 0.2 seconds, the second time signal S2 obtained directly from the frequency divider has a repetition period of 0.0625 seconds, and the third time signal S3 has a repetition period of 0.25 seconds.

The first time signal S1 of 0.2 seconds is input to the clock input terminal of the counter circuit 202, and this counter circuit 202 has its output terminals Q0 to
A pulse having a waveform as shown in FIGS. 34 a to 34 c is outputted to Q5. Specifically, this counter circuit 2
02 has a 14-stage binary counter and a logic circuit connected to the counter. Output terminal Q0
-Q2 is an output terminal of a binary counter, which outputs pulses with frequency-divided waveforms as shown in FIGS. 34a to 34c. Output terminals Q3 to Q5 are output terminals of the logic circuit, and pulses having waveforms as shown in FIG. 34e and f are obtained.

Next, the operation will be explained.

Control of Normal Game State Under the normal state after the power is turned on, the third time signal S3 from the reference time generator 201 is transmitted through the OR gate 203 to the lower lamps LA to LE.
It is applied to the clock input terminal of advance counter 204.
For this reason, the lower lamps LA to LE connected to each decimal output terminal of the decimal counter 204 are lit sequentially at intervals of 0.25 seconds of the clock input repetition period, and their lighting states are cycled. Further, normally, the movable piece 11 closes the variable prize winning device 10 with respect to the game ball. However, when a ball hits the specific winning holes 8, 9, the first solenoid SOL1 (Fig. 4) is activated as follows, and the movable piece 11 is in the first state (second state) in which no game ball enters the prize. The open state shown in FIG. 3 is converted from the closed state shown in FIG.

(a) Winning a prize in the first specific winning hole When the first operation detection switch SW1 is turned on after winning a prize in the specific winning hole 8, 8, the waveform shaping circuit 20
Flip-flop FF1 is set via the output terminal Q, and its output terminal Q is inverted from H level to L level. The Q output of flip-flop FF1 is applied to one input terminal of a two-input AND gate 207 through an OR gate 206, and the
Open the AND gate. Through this AND gate 207, the second time signal S2 (0.0625 seconds) from the reference time generator 201 is sent to the decimal counter 20.
4 and, as a result, the lower lamps LA to LE connected to the decimal counter 204, with a faster repetition period,
Lights up and cycles. Also, flip-flop FF
As the output terminal of 1 becomes L level,
AND gate 208, which had been at H level until then
The output of disappears, and via OR gate 209,
The reset state of the counter circuit 202 is released, and the counting operation of the counter in the counter circuit 202 is started.

0.8 seconds after the start of counting, an output pulse shown in FIG. 34a is generated at the output terminal Q0 of the counter circuit 202, and a movable-piece actuation signal S4 is generated at the two-input AND gate 210, which is opened by the Q output of the flip-flop FF1. Movable piece actuation signal S4
is sent to the solenoid drive circuit 211, and the first
energize solenoid SOL1 for 0.5 seconds to move movable piece 1
Open and close 1 once.

1.3 seconds after the start of counting, the output pulse shown in FIG. Flip-flop FF1 is reset via 213;
It becomes the initial state. When flip-flop FF1 is reset, the lighting circulation speed of the lower lamps LA to LE returns to the original, relatively slow repetition period. Also, since the output of flip-flop FF1 returns to H level, AND gate 20
8 becomes H level, and the count circuit 20
2 returns to the reset state.

(b) Winning a prize in the second specific winning hole If a winning occurs in the second specific winning hole 9 and the second operation detection switch SW2 is activated, the movable piece 11
performs opening and closing operations only twice under the control described below.

First, when the second operation detection switch SW2 is activated, the flip-flop FF2 is set through the waveform shaping circuit 214. The Q output of flip-flop FF2 causes flip-flop FF
1 is also set, and the reset state of the counter circuit 202 is released. Therefore, the movable piece actuation signal S4 is generated 0.8 seconds after the start of counting, and the process in which the movable piece 11 opens and closes once is the same as in the case of winning the first specific prize opening.

However, in the case of winning in the second specific winning opening, the output of the flip-flop FF2 becomes L level, so the two-input AND gate 212 is closed. Therefore, at the time when the above-mentioned 1.3 seconds have elapsed, the output terminal Q4 of the counter circuit 202
Even if the output pulse shown in FIG. 34e occurs, the two-input AND gate 212 outputs the reset signal RE
does not occur. Therefore, the count of the counter circuit 202 progresses, and 3.2 seconds after the start of counting, an output pulse shown in FIG. 34c is generated at the output terminal Q2 of the counter circuit 202. This pulse passes through OR gate 213 to flip-flops FF1 and FF.
2 reset input terminals R, and resets these flip-flops FF1 and FF2.
The outputs of both flip-flops FF1 and FF2 are high.
As a result, the output of AND gate 208 becomes H level, and counter circuit 202 returns to the reset state.

Before the counter circuit 202 returns to the reset state, a second pulse is generated at the output terminal Q0 of the counter circuit 202, as shown in FIG. Through 211, the first solenoid SOL1 is energized for 0.8 seconds. Therefore, the movable piece 11 performs a total of two opening and closing operations.

Conversion to special mode gaming state During the period in which the movable piece 11 is opening and closing once or twice as described above, the ball that wins using the movable piece as a guide will receive a special prize of the variable winning device 10. When you win a prize in mouth 19 and it is detected by the special prize detector 127 (special prize switch SW3), the maximum
Transition to continuous opening and closing movements up to 18 times. In order to convert to this special mode gaming state, in the circuit shown in FIG. 33, while the flip-flop FF1 maintains the set state, a game ball enters the special winning slot 19 and the special winning switch SW3 is turned on. thing,
To be more precise, the AND gate 216 is
It is necessary that the special winning switch SW3 is turned ON while being opened by the Q output of the flip-flop FF1 provided through the OR gate 217.

Now, when the special prize switch SW3 is turned on,
AND gate 216 via waveform shaping circuit 215
A pulse is applied to. AND gate 216 is
At this point, the Q of flip-flop FF1 is
Opened by output. Therefore, the pulse is
Flip-flop FF through AND gate 216
3 and sets the flip-flop, the Q output of flip-flop FF3 goes to H level,
The output becomes L level. At this time, the same pulse is sent to the counter circuit 20 via the OR gate 209.
2 to the initial state, and OR gate 21
8, the flip-flop FF4 is brought to an initial state.

When flip-flop FF3 is set and its output is inverted to L level, the reset state of counter circuit 202 is released, counter circuit 202 starts its counting function, and flip-flop FF4 is switched from output terminal Q1 of counter circuit 202. It becomes a state in which it expects a pulse to be sent. That is, the output of flip-flop FF4 is still at H level.

(a) Appearance of special display member The H level Q output generated when flip-flop FF3 is set is the special display device 1.
It is sent to a three-input AND gate 219 placed in front of the solenoid drive circuit 220 of 00. For this reason,
AND gate 219 opens and counter circuit 20
The state is such that a pulse is expected to be sent from the output terminal Q5 of No. 2. At the output terminal Q5 of the counter circuit 202, as shown in FIG. 34f,
A pulse with a pulse width lasting 0.8 seconds from the start of counting by the counter circuit 202, followed by a pulse with a pulse width of 0.05 seconds.
Three pulses are generated with a pulse interval of seconds and a pulse width of 0.15 seconds. This pulse train is applied to the solenoid drive circuit 220 through the AND gate 219, and the second solenoid SOL
2 is energized. For this reason, the special display device 10
Special display member 101 imitating Zjotsky from 0
descends to the position indicated by the solid line in FIG. 16, that is, above the middle front plate 30 imitating a horse, and at that position moves up and down three times. Along with this movement, a rocking piece imitating a whip held by Zjotsky
114 also swings independently. Due to the appearance of the special display member 101, the player can clearly know that the game has been converted to a special mode game, and this increases his/her interest in the pachinko game.

(b) Temporary prohibition of the opening/closing operation of the movable piece When 1.6 seconds have elapsed after the jyotzky appears and the swinging operation is completed as described above, the special display member 101 will be displayed as shown by the dotted line in Fig. 16. Then, it hides behind the upper front plate 24 again. When 1.6 seconds have elapsed after the start of counting, a pulse is generated at the output terminal Q1 of the counter circuit 202, and this pulse is applied to the flip-flop FF.
The clock signal is input to the clock input terminal of No. 4, and the flip-flop FF4 is set. That is, the output of flip-flop FF4 is at L level, and Q
The output switches to H level. flip flop
AND gate 223 is opened by the Q output of FF4. The pulse generated at the output terminal Q0 of the counter circuit 202 is inverted via the inverter 222, and the inverted signal is applied to the solenoid drive circuit 211 via the AND gate 223. As a result, the continuous opening and closing operation of the movable piece 11 is started for the first time. In other words, movable piece 1
1 maintains the first state (closed state) until 1.6 seconds have passed after the start of counting, as shown in FIG. 16, and the movable pieces 11, 11 in the first state During this time, the special display member 101 performs a revealing operation. Therefore, the conversion to the special mode game is clearly perceived by the player.

(c) Starting the background display device, etc.Furthermore, when special prize switch SW3 is turned on and flip-flop FF3 is set,
The H level signal at the output terminal Q of the flip-flop FF3 is applied to the motor drive circuit 221 of the background display device 77. Therefore, the motor 76 of the background display device 77 starts operating, and the gear device 75
The drive roll 71 is rotated via the drive roll 71, and the background carrier 73 moves laterally inside the concave chamber 35. In this embodiment, the background of horse racing will gradually change. Further, the H level Q output of flip-flop FF3 passes through OR gate 206 and opens AND gate 207. Therefore, the second time signal S2 from the reference time generator 201 is
It is added to the input terminal CE of the decimal counter 204,
The lower lamps LA to LE turn on and cycle at a faster repetition rate than usual. Such display conversion creates special interest for players.

The right number display 43 is operated via a right number counter 224 consisting of a down counter, a decoder 225, and a driver (not shown).
“8” is displayed.

Control of special mode gaming state After conversion to the above special mode gaming state, movable piece 1
1 performs opening and closing operations up to 18 times. The reason why the "maximum" of 18 times is written here is that 18 times is a unit cycle of the special mode game, one cycle, and if you further enter the special winning slot 19 during this cycle,
This is because even if the 18 opening/closing operations of the movable piece 11 have not yet been completed, the cycle is interrupted and the first cycle of the next new cycle is started.

For example, when the special winning switch SW3 is turned ON again after the 12th opening/closing operation and the next cycle starts, the next 13th opening/closing operation will not be the 13th of the previous cycle but the first update cycle. Further, the number of update cycles, ie, the number of rights exercise "q" for the special mode game, is allowed up to a maximum of 8 cycles (q=8) in this example. Therefore, if the maximum number of opening/closing operations of 18 times per cycle is maintained, you can expect 18 x 8 opening/closing operations, but conversely, even if it is the first cycle, there will be no chance of winning the special prize opening 19 during that time. Without it, the cycle is designed to end. Further, in this control device, even when the number of winning balls in the normal and special winning holes 18 and 19 reaches a predetermined number (10 in this example), the cycle ends.

(B) Operation before update When 1.6 seconds have elapsed after the jyotzky appears and the oscillating operation is completed as described above, a signal is generated at the output terminal Q0 of the counter circuit 202.
The inverted signal of the pulse every 0.8 seconds is the AND gate 2
23 to the solenoid drive circuit 211. The first solenoid SOL1 is energized for each pulse of this inversion signal, and the movable piece 11 is
For the first cycle, the opening and closing operations will be repeated up to 18 times in a row.

While performing such opening/closing operations, many game balls pass through the movable piece 11 and enter the variable prize winning device 10.
will win the prize. The total number of winning balls is counted by a count switch SW4, and it is checked whether it is within a predetermined number. To be more specific, the winning ball that enters the variable winning device 10 is either a winning ball from the normal winning hole 18 or a winning ball from the special winning hole 1.
Regardless of whether it is a winning ball from 9 onwards, it will be collected at count switch SW4 on the back of the game board, and the count switch will be turned on. Every time the count switch SW4 is turned on, one pulse is sent through the waveform shaping circuit 229 to the winning ball counter 23.
It is input to 0. The winning ball number counter 230 is
Since it has been reset once the special winning switch SW3 is turned on, the winning ball number counter 23
0 is sequentially incremented by one step, and the number display 129 is displayed via the decoder 231 and a driver (not shown).
will display numbers from "1" to "9".

(b) Cycle update Under the restriction of the total number of winning balls occurring during the above cycle to 9, and before the above 18 opening/closing operations are completed, the special winning hole 19 If there is a winning ball, it will be updated to a new cycle. If the special winning switch SW3 performs the detection operation again during this new cycle, this cycle will be updated to the next cycle with the same operation as above, and if not, the winning ball number counter 2
When 30 counts the number of pulses "10",
The circuit returns to its initial state upon completion of one cycle.

Now, during the first cycle, when special prize switch SW3 turns on, AND gate 2
16 causes the counter circuit 2 to
02, the flip-flop FF4 and winning ball counter 230 are each returned to their initial states, and the same pulse is transferred to the winning ball counter 22.
4 and decrements the contents of the counter by 1. Therefore, flip-flop FF4
As a result of the operation, operations such as lowering of the special display member and temporary prohibition of the opening/closing operation of the movable piece are performed in the same way as when transitioning to the special mode game state described above, while the display on the number display 129 is "0". Return to
The right number display 43 switches from "8" to "7". As a result, the first cycle is interrupted and updated to the second cycle, and the display content of the right number of times display 43 indicates the remaining number of times that can be updated. Visually displaying the contents of the counter in this way is interesting for players.

From the 2nd cycle onwards, special prize opening 1 will be available again.
The same is true when winning 9, and the same operation is repeated. Again, each update point, that is, the break of each cycle is an operation in which the movable piece 11 is closed for 1.6 seconds, and during that time, the special display member 1
The action in which 1 appears is clearly perceived by the player. In addition, at the same time as the cycle update that is performed every time the special prize switch SW3 is detected,
The rights number counter 224 temporarily decrements its contents.

Fortunately, if it is updated to the 8th and final cycle, the special mode game state will be completed after performing the opening/closing operation a total of 18 times as promised in that cycle. That is, when a prize is won in the special winning slot 19 in the middle of the seventh cycle, the content of the number of rights counter 224 becomes "1", and the number of rights display 43 indicates that the remaining number of times is "1", and at the same time The output of the detection circuit consisting of the inverter 227 and OR gate 228 connected to the counter falls to the L level. For this reason, the 8th cycle (final cycle) currently underway
In this case, special prize-winning switch SW3 after that
AND gate 216 no longer accepts the ON signal.

A total of 18 opening/closing operations were performed as promised in the eighth cycle.

The counter circuit 202 outputs the 34th signal to its output terminal Q3 when the 18 opening/closing operations are completed, more precisely 29.6 seconds after the start of counting.
Generate the pulse shown in Figure d. This pulse is
Flip-flop FF through OR gate 226
3 and resets the right number counter 224. When the Q output of flip-flop FF3 falls to the L level, the motor 76 of the background display device 77 stops, and the blinking movement speed of the lower lamps LA to LE returns to the normal relatively slow speed. Also, as the output of flip-flop FF3 returns to H level, the counter circuit 2
02 and flip-flop FF4 are held in reset. In this way, the entire circuit system returns to its initial state. The pachinko machine changes from the special mode gaming state to the normal gaming state.

Forced switching to normal gaming state If one cycle ends without being updated, that is, if a total of 18 opening/closing operations are completed, with each opening/closing operation unit being 1.6 seconds, the counter When 29.6 seconds have elapsed after the circuit 202 started counting, a pulse shown in FIG. 34d is generated at the output terminal Q3 of the counter circuit 202, and the pulse is as follows.
Flip-flop FF3 through OR gate 226
and resets the right number counter 224. Therefore, as described above, the entire circuit system is returned to the initial state, the special mode gaming state is forcibly canceled, and the normal gaming state is returned. Therefore, from now on, unless a series of operations from winning to the first and second specific winning holes 8 and 9 are performed, the special mode gaming state cannot be entered. This disadvantageous situation for the player occurs because there is no subsequent winning in the special winning slot 19 during one cycle of the above-mentioned 18 times as one unit.

On the other hand, while performing the opening/closing operation, the movable piece 1
When a large number of game balls win a prize in the variable winning device 10 through 1 and the total number of winning balls reaches 10, the content of the winning ball number counter 230 becomes "10". For this reason, it was connected to the winning ball counter 230.
A termination signal is generated in the decoder consisting of AND gate 231 and resets flip-flop FF3 and rights counter 224 through OR gate 226. Therefore, as described above, the entire circuit system is returned to the initial state, and the special mode gaming state is also forcibly canceled.

As mentioned above, the special mode gaming state as a reserved right that allows the variable winning device to be in an open state with a high probability of winning occurs on the premise that a winning is made to a specific winning opening and a winning is made to a special winning opening. Therefore, in order to enter the special mode gaming state, the player needs to control the ball so that it enters the specific winning slot and the special winning device. In addition, once the special mode gaming state has been converted, in order to prevent the special mode gaming state from disappearing midway through, it is necessary to enter the special winning slot within a certain period of time, but, If too many batted balls are allowed to win prizes, the opportunity to renew the cycle will be lost early, and as a result, many prize balls will not be obtained. Therefore, it is necessary to devise ways to appropriately control the ball, which greatly enhances the interest of the pachinko game.

Modified Example of Variable Prize-winning Device Next, a modified example of the variable prize-winning device 10 will be described with reference to FIGS. 24 to 32.
Note that the same reference numerals are used for the same components as in the embodiments shown in FIGS. 1 to 20 above. In the embodiment described below, the auxiliary movable piece 12, the middle front plate 30, and the special display device 100 are not present, and therefore, the configuration related thereto is also not present.

Upper part of the board In FIGS. 24 and 25, in order to enlarge the back space covered by the upper front plate 24, the top prize opening 16 is omitted and only the side prize opening 17 is provided close to each other. . Upper front plate 2
4, unlike the case of the first embodiment, is provided with a right number display 43 consisting of a 7-segment LED and a display window 32 therefor. The display window 32 is
For example, an opening as a window frame is provided in the upper front plate 24, and this opening is covered from the back side with a transparent or semi-transparent plate. 7 segments like this
When installing an LED, placing a composite member such as a transparent plate in front of it can prevent damage from being hit by a ball or the like. The right number display 43 connects its printed wiring board 431 to the upper front plate 24.
It is attached to the upper front plate 24 by screwing it to a mounting boss 432 protruding from the top. In this example, the 7-segment LED on the upper faceplate 24
is used to display the number of wins, that is, to inform the player of the number of successive jackpots, but it can also be used for any display related to the state of the game. In addition to the 7-segment LED display, for example, a lamp, a light emitting element, etc. can be used as the game status display, and it can also be used in an analog manner. Furthermore, the mounting location is not limited to the upper front plate. For example, it can also be provided on the lower front plate 60.

Middle part of the board (a) Movable piece Unlike the first embodiment described above, the movable piece 11 includes a flat guide part 11A extending outward from a rotating base 11C, and a region of the flat guide part that is not rotatable. It has only a stopper portion 11D extending inward from the base portion 11C. The plate-shaped main portion 11B does not exist, and therefore the notch 11E does not exist either.

As shown in FIGS. 24 and 32A, the movable piece 11 closes when the outer end of the stopper portion 11D abuts against the inside of the lower upright wall, that is, the lower receiving frame 61 located below the movable shaft 13. state (first state), and when it is in the open state (second state), the inner end of the stopper portion 11D, more precisely, the concave surface 1 provided at the end of the stopper portion 11D.
The tip of 1H comes into contact with the lower surface of the branch head 310 of the branching shelf branching means, as shown in FIG. 32B. However, the closed position of the movable piece 11 is not controlled by the stopper part 11D, but by a movable member receiving part 68 such as a pin at the upper limit position of the rotation range of the guide part 11A, as shown in FIG. 27A. The lower surface of the movable piece 11 itself can also be brought into direct contact with the lower surface of the movable piece 11. Further, the open position of the movable piece 11 is controlled by the branching section head 31 of the branching shelf branching means.
0, as shown in FIG. 27B, an L-shaped protrusion 11J provided in advance on the inner end of the movable piece 11 is connected to the diverter shelf 42 of the diverter shelf branching means.
This can also be done by making it come into contact with the movable piece receiving part 420A provided on the lower surface of the 0. The reason why the movable member receiving portion is provided separately and the position is regulated by bringing it into contact with the movable piece is that if the position of the movable member 11 in the first and second states is regulated on the drive source 87 side, the movable member 11 can be moved. This is because the pieces become loose. By accurately controlling the position of the movable member without causing play, it can be used for a long time.

FIG. 28 shows a configuration example in which the weight of the movable piece 11 is reduced without impairing its strength. The movable piece 11 in the example shown in FIG.
The insertion boss portion 119 (corresponding to the rotating base portion 11C in FIG. 10) for A is left, and the other portions are hollow. That is, the side wall 11 stands up with a thickness A approximately equal to the thickness B of the design part toward the rear by the plate-shaped design part 116 existing on the front side.
7 is provided, thereby forming an unformed space 118 that is even larger than the unformed space 11G shown in FIG. Due to the existence of this large unformed space 118, the movable piece 11 is extremely lightweight, and the capacity of its driving source is reduced.
The drive mechanism etc. can also be made smaller.

(b) Concave chamber upper and lower surface display section In the first embodiment (FIGS. 4 and 5), only the inner circumferential lower surface 36B of the peripheral wall 36 is configured as the display section (lower surface display section) 50. but,
In this second embodiment, as shown in FIG. 25, an upper surface display section 500 is provided not only on the lower surface but also on the inclined portion of the inner circumferential upper surface 36A.

In order to configure the upper display section 500 and the lower display section 50, boss sections 580 and 58 are provided that extend rearward from the outer surface of the peripheral wall 36, and the display section substrate 5 is attached to the boss sections 580 and 58.
40 and 54 are screwed. However, unlike the first embodiment, the display substrates 540 and 5
4 carries an upper lamp 550 and a lower lamp 55 made of LED instead of miniature light bulbs. Further, a lamp part housing 50A consisting of a number of small holes corresponding to the number of lamps is provided on the inner circumferential upper surface 36A and lower surface 36B of the peripheral wall 36, and the head of each lamp (LED) is directly exposed in the lamp housing part. There is. As a result, it is arranged at a position that does not obstruct the flow of winning balls to each space distribution means 62. The reason for this configuration is that if each lamp (LED) protrudes from the circumferential surface of the concave chamber, the probability of winning a prize in the space distribution means 62 will change when a winning ball hits each lamp. be. By placing the lamps in the lamp storage section in this way, it is possible to bring out the decorative effect of the LEDs in the recessed chamber 35, and to control the lighting of these LEDs in different ways depending on each aspect of the game. Therefore, the player can also know the mode of the game based on the lighting state of the LED.

The top lamps 550 are carried by a common top display substrate 540 in groups of three stages. On the other hand, the lower lamps 55 are also carried in groups of three stages, but the lower display substrate 54 is not a common substrate among them, but is divided into a plurality of partial substrates 54A and 54B. In this embodiment, the upper partial substrate 54A
Two groups of lower lamps 55 are supported on the lower partial substrate 54B, and one group of lower lamps 55 is supported on the lower partial substrate 54B.

When arranging multiple lamps in groups on a slope in this way, it is important to divide the lamp mounting board into partial boards and mount the lamps in steps when the slope is relatively long. This technique has the advantage of not constricting the space for other mounting members and the like. That is, since it is attached to the outer peripheral surface of the peripheral wall, the lamp can be attached without increasing the size of the variable prize winning device. Also, if the lamp mounting board is divided into multiple units and installed in stages, even if a lamp burns out, you can just remove the mounting board in that location and replace it. Different displays can be displayed depending on the mounting board for each unit. When installing lamps in stages, it is not necessarily necessary to divide them into partial boards corresponding to the number of stages of the lamps.
By attaching an appropriate number of stages of lamp groups to one partial board, the number of partial boards can be reduced.

Figure 29 shows that using partial boards one step at a time,
An example is shown in which upper lamps are installed in two stages on the sloped part of the inner peripheral upper surface 36A, and lower lamps are installed in four stages on the sloped part of the inner peripheral lower surface 36B. Top display board 540
is divided into two partial substrates 540A and 540B, and the lower display portion substrate 54 is divided into four partial substrates 54A, 54B, 54C, and 54D.

(C) Diversion Shelf Branching Means As shown in FIGS. 24 and 25, the diversion shelf branching means in this embodiment is composed of a diversion shelf branching member 400 imitating a locomotive. The concave chamber 35 is an "upper flow space",
It is divided into "lower distribution space".

The flow divider shelf branching member 400 not only has a central branch part 410 extending in the front-rear direction inside the recessed chamber 35 and flow divider shelves 420 extending laterally on both sides thereof, but also has a branch part head located outside the recessed chamber 35. Part 31
0 (FIG. 26). Branch 4
10 imitates the body of a locomotive, has a rounded shape that allows winning balls to be distributed to the left and right, and can be split into two for assembly. As a result of the existence of the branching shelf branching member 400 imitating a locomotive, the effective space within the recessed chamber 35 is relatively narrow compared to the first embodiment in which the middle front plate 30 is provided. Even when a relatively large amount of winning balls are generated in the space (space), they are distributed to the left and right by the branching part 410, and since the diversion port 39A exists continuously with the distribution shelf 420, the balls are not packed together. In addition, as a result of being divided into an upper part flow space and a lower part flow space, only a limited number of winning balls can go to the space distribution means 62 at the bottom of the concave chamber, so there is no chance of ball clogging in the distribution means. None. If the structure is such that all winning balls are guided to the spatial distribution means 62, balls will be packed together. The winning balls distributed in this way in the concave chamber 35 are distributed from the outlet provided for each winning hole 18, 19 to the winning balls on the back of the game board in the same manner as described in the first embodiment. Collection gutter 1
41 to be discharged and collected. In addition, the winning ball collection gutter also has a discharge port 144 as shown in Fig. 20 or 21.
Since the balls are configured with steps, even if a large number of winning balls arrive, they can be reliably ejected to one ball. By configuring the ball flow paths to be continuous in this way, it is possible to eliminate ball clogging, and since the winning balls are quickly guided, each detector 127, 128 can be pushed quickly, so each detector can also be quickly pushed. This means that games that can be reliably detected can be played reliably.

The front part of the branch head 310 is configured as a lens part 311 made of a colored translucent material, and inside the branch part 410 there is a rear face 3.
An illumination lamp 411 attached to 7 is housed. Further, a small cylindrical part 312 imitating the headlamp part of a locomotive is provided at the upper part of the branch head 310, and a small cylindrical part 312 is attached to a base plate 313 disposed inside the branch part 41. An illumination lamp 314 is placed so that it can be seen by the player. These illumination lamps 314, 411 can be used as means for generating or otherwise visualizing certain features.

The front part of the above-mentioned branch head 310 is located at the player's eye level and is a part provided in the variable prize winning device that is the main part of the game content, so the player can view the display as the game progresses. This is a convenient location for understanding the situation from the outside. Therefore, instead of the illumination lamp 314 or 411 as described above, a display consisting of a 7-segment LED is provided,
It is also possible to visually display the continuation status of the game, etc. In any case, the internal lighting lamps etc.
By covering with a transparent plate such as the lens portion 311, it is protected from damage caused by a hit ball.

The branching section head 310 is connected to the window section 21, that is, the branching shelf 4
20 and protrudes forward by a distance L1 (FIG. 26). Therefore, as in the case of the first embodiment, there is no problem in which a hit ball that has won a prize does not become a prize and flies out of the apparatus again.
The lateral width W (FIG. 26) of the branch head 31 is:
It is larger than the distance between the inner ends of the movable pieces 11, 11 when opened. Therefore, the branch head 31 can function as a stopper for the movable pieces 11, 11.
The upper surface 420A of the flow dividing shelf 420 is tilted rearward so that the vertical height differs by a distance L2 (FIG. 26).

The flow dividing shelf branching member 400 is mounted by cantilevering it near the window on the side surface of the peripheral wall 36 of the recessed chamber. That is, as shown in FIG. 26, the locking portions 42B made of small flat protrusions provided at both ends of the flow dividing shelf 420 are connected to the locking portions 42B made of small flat projections provided at both ends of the flow dividing shelf 420, and the locking portions 42B made of small flat protrusions provided at both ends of the flow dividing shelf 420 are connected to the opposite side made of a groove provided from the starting end of the window portion on the side surface of the peripheral wall 36 of the concave chamber. It is inserted into the locking part 36C. This configuration is similar to the first embodiment, and the distribution shelf branching member 40
Installing the 0 is extremely easy.

(d) Illumination inside the concave chamber Returning to FIG. 24, a side illumination device is provided on the side of the concave chamber 35 in order to illuminate the inside of the concave chamber. That is, an illumination window 361 consisting of a window frame 362 and a colored translucent member 363 covering the window frame 362 is provided slightly above the left and right side portions of the peripheral wall 36 of the recessed chamber, and an illumination window 361 is provided on the outside of the side portion of the peripheral wall 36 of the recessed chamber. , an illumination lamp 36 is provided corresponding to the illumination window.
4 are arranged. The illumination lamp 364 can illuminate the inside of the recessed chamber 35 through the illumination window 361. On the other hand, the entire surface of the flow divider shelf branching member 400 is coated with a reflective material, such as silver plating, gold plating, or the like. However, in this specification, the term "reflective material" means that a reflective surface is formed, and does not necessarily mean that the diversion shelf branching member 400 is formed of a different material. It's not a thing.

The light emitted from the illumination lamp 364 is transmitted through the illumination window 361.
By passing through the semi-transparent member 363 , the light is converted into a color unique to the semi-transparent member 363 , for example, red, and enters the recessed chamber 35 . The red light that has entered the concave chamber 35 directly illuminates the inside of the concave chamber 35, and
The light hits the reflective material covering the flow divider shelf branching member 400 and is reflected. Due to this reflective action, the concave chamber 3
The interior of No. 5 and the diversion shelf branching member 400 are converted into a color different from the color that they themselves have.
In other words, the color stands out throughout the interior of the recessed chamber 35. Therefore, when the illumination lamp 364 is turned on, the player can see the concave chamber in the normal state and the concave chamber in the special mode as if they were completely different.

By arranging LEDs etc. on the top or bottom of the concave chamber,
Merely blinking or displaying the progress of the game is insufficient to decorate the variable prize winning device, especially in the concave chamber, and the branching shelf branching member, which is a concave decoration provided in the concave chamber, is also insufficient. It feels like it just exists. However, by combining the side illumination device and the diverting shelf branching member 400 covered with a reflective member as described above, it is possible to obtain a unique decorative property that was not available in the past. , coating with a reflective material such as gold plating has the effect of increasing the strength of the branch head 310, the branch 410, and the diverter shelf 420, and also has the effect of smoothing the introduction of winning balls.

Middle part of the back surface of the board As shown in FIG. 21, on the rear surface 37 of the recessed chamber 35, a drive source mounting plate 80 (FIG. 21) is provided at intervals.
is installed. The rear member 70 as shown in FIG. 12 is not present.

As shown in FIGS. 30 and 31, each of the plunger shafts 88 of the two electromagnetic solenoids 87 supported in parallel to each other on the drive source mounting plate 80 has a shaft accommodating section 91 at its tip. An operating lever 90 is independently fixed. Due to the presence of the shaft storage portion 91, the plunger shaft 88
Relative wobbling between the actuating lever 90 and the actuating lever 90 is prevented. In the first embodiment, in order to hold the actuating lever 90 parallel to the drive source mounting plate 80, the actuating lever upright portion 92 (the first
3), but in this embodiment, such an actuating lever standing portion 92 does not exist. That is, instead of this operating lever upright portion 92, a plate-shaped connecting member 9 is used.
20 is bridged between the two left and right operating levers 90, 90 and pivotally attached to each, so that the connection member receiving surface and the contact surface of the connection member are maintained in the same plane. In other words, the connecting member 920 has a plate shape so that the operating levers 90, 90 are not tilted with respect to the drive source mounting plate 80, but are rotatable in a plane parallel to the drive source mounting plate 80. The levers 90, 90 are connected. This connecting member 920 is connected to the first
Similar to the function of the operating lever upright portion 92 in the embodiment, during normal use, contact friction between the operating lever 90 and the drive source mounting plate 80 is eliminated to reduce the load on the drive source. and smooth operating lever 90
On the other hand, even when an external force is applied in the direction of tilting the operating lever 90, the operating lever 90 is held parallel to the drive source mounting plate 80, and the movable piece always moves smoothly. The role is to guarantee that In addition, since the actuation levers are each connected by a connecting member, this makes the connecting member receiving surface and the contact surface of the connecting member equal, and the gap between the two left and right levers 90 is large even if there is play in the plunger shaft. However, the opening and closing operations of the movable piece 11 can be performed accurately. Furthermore, when the left and right movable pieces are in the open state, the tilting angles of the movable pieces can be made equal, and the opening and closing operations of the left and right movable pieces can be performed simultaneously.

Therefore, the player does not feel uncomfortable.

The reason why the connecting member 920 is rotatably connected to the two left and right operating levers 90, 90 without being fixed is that the left and right movable wings 11 can be operated independently on the left and right sides, as in the first embodiment. , while playing pachinko,
This is to ensure that even if a ball is caught in either the left or right main movable wing 11, the other main movable wing 11 closes regardless of this.

FIGS. 32A and 32B show the engagement positional relationship between the engagement hole 93 and the pin 48 when the electromagnetic solenoid 87 is de-energized and when it is energized, and the relationship between the movable piece 11 and the tongue 85 that is the auxiliary receiving surface of the operating lever. shows.

In the closed state shown in FIG. 32A, a slight gap (first gap) 97 of about 0.5 mm to 1 mm is formed between the tongue 85, which is the auxiliary receiving surface of the operating lever, and the lower surface of each of the left and right operating levers 90. This prevents the plunger shaft 88 from coming off during assembly, and prevents the movable piece 11 from wobbling beyond the allowable limit due to wear. In addition, in the open state shown in FIG. 32B, the second gap 98 is the stroke margin of the plunger.
remains, and the stability of the open position is maintained.

(Effects) As described above, the present invention provides the variable prize winning device 1
When the movable piece 11 of 0 converts to the second state, the length of the movable piece 11 of the variable prize winning device 10 is determined so that it protrudes laterally longer than the diameter of the game ball, while the movable piece 11 in the game area 3 is When the movable piece 11 is converted to the second state, it does not interfere with the conversion operation of the piece 11, and is placed on the side at a distance L that is less than the diameter of the game ball from the tip of the movable piece in front of the movable piece 11. In addition to disposing the side member 5A, a channel forming member 5B is disposed that guides the game ball from above the side member 5A toward the outer side of the side member. 1 state, the flow of game balls is directed between the first channel (arrow P1) passing toward the outer side of the side member 5A and the movable piece 11 and the side member 5A. On the other hand, when the movable piece 11 converts to the second state, the second flow passage is closed by the movable piece 11, thereby causing the lateral The variable winning device 1 is moved along the movable piece 11 from the winning winning area 15 above the member 5A.
A third flow path (arrow P3) for guiding the game ball is formed in the inside of the ball.

Since the side member 5A is located further forward than the tip of the movable piece 11 when the movable piece 11 is converted to the second state and the second flow path P2 is closed, the side member 5A is located further forward than the tip of the movable piece 11. In cooperation with
Guide inside. In other words, without reducing the winning probability of a batted ball under the second state, and without reducing the player's interest in playing pachinko,
The same function as the conventional movable piece can be achieved with a shorter movable piece 11. As a result of the movable piece 11 being short, the capacity of the electromagnetic solenoid normally used as an electric drive source is also small, and the entire winning device can be assembled compactly. Furthermore, since the damage caused to each joint is reduced, the durability of the main variable prize winning device itself can be increased.

Furthermore, since the area within the radius locus of the rotational movement of the movable piece 11 becomes smaller, and the game area 3 on the game board surface becomes larger than before, conventionally, the movable piece 11 is provided to ensure free rotation. Nails or other obstructing members can also be provided in areas of the game board where this is not possible. By providing the obstacle member, when the movable piece is in the first state, the direction of the ball that flows down the side of the variable prize winning device can be changed randomly by the side member 5A. It is possible to prevent the game from becoming monotonous, and in this respect, it is possible to make the pachinko game more interesting than before. In addition, since the downward momentum of the batted ball is weakened, when the movable piece is in the second state, the impact of the hit ball hitting the movable piece is also weakened, causing the ball to swing wildly on the surface of the movable piece, or cause the movable piece to The durability of the stopper part etc. may be reduced,
Inconveniences such as when a ball bounces off the surface of the movable piece and damages the front glass do not occur. Furthermore, the side member divides the flow into the first channel where it is difficult to win and the second channel where it is easy to win, so by adjusting the winning area expansion member, the winning rate to the main variable winning device can be increased. This makes management at pachinko parlors easier.

A variable prize winning device is provided in which movable pieces that can be converted between a first state in which it does not accept a hit ball and a second state in which it is easy to accept a hit ball are pivotally supported in an opposing manner, and below the movable winning device in the gaming area, there is a variable prize winning device in which a batted ball wins a prize. When the movable piece changes from the first state to the second state with respect to the electric drive source,
In a pachinko machine equipped with a first specific winning device and a second specific winning device that generate an activation signal to change the state, the length of the movable piece is such that when converted to the second state, the game ball is set so as to protrude laterally longer than the diameter of the movable piece, and within the gaming area does not interfere with the conversion operation of the movable piece, and when the movable piece is converted to the second state,
A side member is disposed at a distance equal to or less than the diameter of the game ball from the tip of the movable piece in front of the movable piece. A channel forming member for guiding the ball is disposed, and when the movable piece is in the first state, the flow of the game ball is directed to the first channel through which the flow of the game ball passes toward the outer side of the side member.
The flow is divided into a flow path and a second flow path passing between the movable piece and the side member. On the other hand, when the movable piece is converted to the second state,
The second flow path is closed by the movable piece, thereby forming a third flow path that guides the game ball from the winning possible area above the side member into the variable winning device along the movable piece. A pachinko machine featuring
