This ball detector is a normal symbol start switch 6 for starting variable display of symbols on the normal symbol display device 5, and constitutes an operating means of a variable winning device consisting of a common electric accessory 8.

Therefore, when the ball flowing down the gaming section 3 enters the ball entrance 33 and flows into the closed space section 24 through the ball guide gutter 35, the ball passes through the ball detector (normal symbol start switch 6) on the way. ) and then falls onto the fence board 26. The fallen ball flows into the circular recess 27 by the ball guide rib 30 and the ball guide groove 29, and immediately after the ball flows in, there is sufficient downward force so that the ball goes around the edge of the circular concave section 27, but when the downward force weakens, The balls fall onto the bottom plate 31 from one of the drop ports 28, return to the game section 3 through the ball outlet 32, and flow down the game section 3. In addition, when the ball falls from the central drop opening 28 onto the bottom plate 31, it flows down through the center of the bottom plate 31 from the center of the ball outlet 32 to the center of the game board 1, and flows down to the center of the game board 1 provided below.
There is a high probability that it will flow into Further, in the illustrated embodiment, a ball guide piece 30' is vertically provided from the lower edge of the ball guide trough 35 toward the fence plate 26 so that the falling direction of the balls flowing in from the left ball inlet 33 is stabilized. .

The ordinary electric accessory 8 placed below the central accessory 7 has a structure as shown in FIGS. 7(A) to 7(D), for example. That is, the base plate 36 has a pocket 37 on the front surface thereof for receiving a batted ball, and a pair of rotating blades 38 on the left and right sides of the upper opening edge of the pocket 37. This pocket 37
is fixed to the lower half of the central part of the base plate 36 and communicates with a through hole 39 formed in the base plate 36, so that balls flowing from the upper opening can flow out to the rear of the game board 1 through this through hole 39. It is structured as follows. A decorative plate 40 is attached to the front surface to cover the opening, and two support shafts 41 are planted in the decorative plate 40 facing rearward, so that the rotary wing pieces 38 can be freely rotated. Pivotally supported.

The rotating wing piece 38 has a recess 38a at its base end on the shaft support side, and a swing protrusion 42a of a swing member 42, which will be described later, is loosely fitted into the recess 38a through a through hole formed in the base plate 36. . The operation transmission mechanism for rotating the rotary blade 38 converts the linear motion of the sliding plunger 44 by the excitation of the electric solenoid 43 into the rotational motion of the rotary blade 38, and the mechanism connects the plunger 44 to the interlocking rod. 45 and the above-mentioned swinging member 42 are pivotally connected by a pin 46. Note that two interlocking rods 45 are normally arranged on the left and right sides of the electric solenoid 43, and are connected to both the left and right ends of the swinging member 42.

A ball detector (for example, the special symbol start switch 10) is provided at the upper end of the opening of the pocket 37, so that it is possible to detect a ball flowing between the rotary blades 38. The ball that has passed through the ball detector (10) is taken into the rear of the game board 1 as a winning ball.

In the normal electric accessory 8 configured as described above, in a normal state, the normal electric solenoid 43 is demagnetized, the plunger 44 is retracted by the bias of the return spring 47, and the swing protrusion 42a of the swing member 42 is moved. (Fig. 7
(C)) Although the rotating wing pieces 38 are wide enough to allow one ball to pass through between their tips, they are in a state where it is difficult to provide a profit to the player. On the other hand, when the normal electric solenoid 43 is energized, the plunger 44 slides, so the swinging member 42 swings about the support shaft 48 via the interlocking rod 45, and the swinging protrusion 42
A can be rotated downward to open the rotary wing pieces 38 to change the state to a state where balls can easily flow in, thereby giving a profit to the player (state shown by the broken line in FIG. 7(A)).

In the illustrated embodiment, a solenoid is normally built into the electric accessory 8, but this solenoid may be an external type that is attached to a game board or the like and communicated via a link mechanism or the like. You can also do it. Moreover, the above-mentioned ordinary electric accessory 8 is set at the starting port of the special symbol display device 4 mentioned above in this embodiment, and the ball detector functions as the special symbol starting switch 10.

Therefore, the ball entrance 33 of the central accessory 7 described above

On the other hand, below the ordinary electric accessory 8, there is a component of a game state converting means that can convert the game development into a first state that is disadvantageous to the player and a second state that is advantageous to the player. A big prize opening 9 is arranged. This big prize opening 9 has a movable member 49 that moves when a specific condition is met, and is configured so that the movable member 49 normally prevents balls from entering. Further, a specific area facing the continuation switch 50 is formed in the big prize opening 9, and the movable state of the movable member 49 is continued on the condition that the ball passes through this specific area. Furthermore, a 10 count switch 51 is placed on the most downstream side so as to detect all the balls that have flowed into the grand prize opening 9, and the mounting base can be used to check how many balls have flowed into the grand prize opening 9 so far. 1 provided on the lower decorative part 53 of 52
It is visually displayed by the 0 count indicator light 54. In the illustrated embodiment, a specific area is formed in a protruding manner approximately at the center of the front side of the mounting base 52, and a passing type ball detector is provided in this specific area, and a ball passing opening of the ball detector is provided in this specific area. A closing member 55 is slidably provided above the ball passage hole so as to cover the ball passage hole,
This closing member 55 is connected to the large prize opening solenoid (
SOL) via a lever mechanism. Furthermore, movable members 49 are provided on the left and right sides of the specific area, and the movable members 49 are connected to the drive source via a lever mechanism.According to the illustrated embodiment, the movable members 49 move to the specific area. It is configured in a pantograph shape so that it can move in parallel to the horizontal direction.

[0022] The above-mentioned big prize opening 9 is not limited to the configuration of the embodiment, but can be converted into a state advantageous to the player when a specific condition is met, and at least the specific area where the continuation switch 50 faces and all Any configuration may be used as long as it includes a 10-count switch 51 that can detect a ball. For example, it may be a so-called attacker type variable winning device having a horizontally long gate.

When the ball fired by the player flows down the gaming section 3 and enters the winning hole 12, the big winning hole 9, the top winning hole 19, etc., 15 prize balls are paid out and the special symbol starting hole 11 (normal It is set so that seven prize balls are paid out when a player wins a prize (including the electric accessory 8).

[0024] When the ball hits the special symbol starting port 11,
The special symbol start switch 10 is turned on, and the special symbol display device 4 starts displaying the symbols in a variable manner for a predetermined period of time (for example, about 6.5 seconds).
5 seconds or more), the symbols are sequentially stopped, and if the combination of symbols displayed by the special symbol display device 4 matches a predetermined winning symbol, the big prize opening 9 will be approximately 30, for example.
Open for seconds. Incidentally, when the 10 count switch 51 detects 10 balls that have flowed into the big winning hole 9, the big winning hole 9 is closed even before the above-mentioned 30 seconds have elapsed. When the ball flows into a specific area while the big prize opening 9 is open, the continuation switch 50
When turned on, the opening of the big prize opening 9 can be repeated up to 16 times. That is, the game develops in the player's favor, and the player can obtain a large profit.

On the other hand, the ball fired by the player is the central accessory 7.
When the ball enters the ball entrance 33 provided in the ball guide trough 35, it falls into the closed space 24, and the normal symbol start switch 6 on the way is turned on. When the normal symbol start switch 6 is turned on, the normal symbol display device 5 starts variable display, and stops the variable display after about 6.5 seconds or more, and if the symbol displayed at this time matches the preset symbol, , the normal electric accessory 8 is opened for about 5.5 seconds. In addition, when the normal symbol display device 5 is a multi-digit display device, the normal electric accessory 8 is opened when the combination of symbols becomes a predetermined combination.

When the normal electric accessory 8 is opened, since the normal electric accessory 8 is provided with a special symbol starting switch 10, there is a chance to shift to an advantageous state for the player. Furthermore, since it is possible to store up to four ON states of the special symbol starting switch 10, more chances will arise. If there is a special symbol start memory, it is visually displayed to the player by a special symbol start memory indicator light 25 provided below the special symbol display device 4.

As described above, the normal symbol start switch 6
The ball that has been turned on falls into the closed space 24 and goes around the circular recess 27, thereby prolonging the falling time and increasing the player's sense of anticipation. In addition, this ball is returned to the gaming section 3.
There is a chance to return to and enter one of the winning slots. Furthermore, in this embodiment, the normal electric accessory 8 constituting the special symbol starting port 11 is arranged below the drop port 28, which further increases the player's expectations.

According to the pachinko machine according to the present invention configured as described above, the normal symbol start switch 6 of the normal symbol display device 5 and the special symbol start switch 10 of the special symbol display device 4 are arranged on a series of ball paths. Because of the arrangement, there is a possibility that one batted ball acts on both the normal symbol start switch 6 and the special symbol start switch 10, and the value of one batted ball increases. In addition, since a series of ball paths are formed, if the player can concentrate the ball in the direction of this ball path, the player can aim at both the special symbol starting port 11 and the normal symbol starting port 56 (ball entrance 33). This makes it easier to plan a game strategy. On the other hand, from a game parlor's perspective, it is sufficient to ensure that the balls are scattered appropriately on the board surface of the game board 1, making it easy to adjust the nails. Furthermore, since the normal symbol start switch 6 is arranged in parallel to the central accessory 7 provided with the special symbol display device 4, there is no need to newly provide the normal symbol start port 56 on the game board 1, and the board surface of the game board 1 It is possible to simplify the configuration of
The structure of the ball guiding path and ball approach on the back side of the game board 1 is simplified.

In the above embodiment, the ball that has passed through the ball detector is guided to the front side of the game board 1 through the inside of the central accessory 7, but once the ball has passed through the back side of the game board 1, For example, it may be guided above the normal electric accessory 8 on the front side of the game board 1. In addition, the normal electric accessory 8 in the above embodiment is set to open when the symbol on the normal symbol display device 5 matches a predetermined symbol, but it can be opened directly by passing through the ball detector. You may also do so.

That is, the function of a prize opening and the function of a starting opening can be provided in the same ordinary electric accessory 8.

This ordinary electric accessory 8 has a pocket 37 on the front surface of the base plate 36 for receiving a ball, and a pair of rotary blades 38 on the left and right sides of the upper opening edge of the pocket 37, and is in a closed state. A ball detector attached to the switch frame 57 is provided between the tips of the rotary blades 38. The pocket 37 is fixed to the lower half of the central part of the base plate 36 and communicates with a through hole 39 formed in the base plate 36, so that the ball that has passed through the upper ball detector and the rotary blade in the open state can be stored in the pocket 37. The ball guided by the piece 38 and flowing in can be taken into the rear of the game board 1 through the through hole 39. In the illustrated embodiment, the ball that has passed through the ball detector falls into the pocket 37, but by providing a bottom partition plate on the switch frame 57, the rotating blade 38 allows the ball to fall into the pocket 37.
When the balls flow into the interior, they can be taken into the rear of the game board 1 separately from the balls.

A decorative plate 40 is attached to the front surface of the pocket 37 to cover the front side of the pocket 37 and the rotating blade 38, and the two support shafts 41 are attached to the decorative plate 40 rearwardly. The rotating wing piece 38 is rotatably supported.

The rotary wing piece 38 has a recess 38a at its base end on the shaft support side, and a swing protrusion 42a of a swing member 42, which will be described later, is loosely fitted into the recess 38a through a through hole formed in the base plate 36. . The operation transmission mechanism for rotating the rotary blade 38 converts the linear motion of the sliding plunger 44 by the excitation of the electric solenoid 43 into the rotational motion of the rotary blade 38, and the mechanism connects the plunger 44 to the interlocking rod. 45 and the above-mentioned swinging member 42 are pivotally connected by a pin 46. Note that two interlocking rods 45 are normally arranged on the left and right sides of the electric solenoid 43, and are connected to both the left and right ends of the swinging member 42.

In the normal electric accessory 8 configured as described above, in a normal state, the normal electric solenoid 43 is demagnetized, the plunger 44 is retreated by the bias of the return spring 47, and the swing protrusion 42a of the swing member 42 is moved. (Fig. 9
(C)), the tip of the rotating blade 38 is brought into contact with the side surface of the switch frame 57 (FIG. 9(A)). In this state, the batted ball flowing down the gaming section 3 can only flow into the ball detector. On the other hand, when the normal electric solenoid 43 is energized, the plunger 44 slides, so the swinging member 42 is moved through the interlocking rod 45.
swings around the support shaft 48 to rotate the swinging protrusion 42a downward, opening the rotating wing piece 38 and changing the state into a state where the ball can easily flow in (the state indicated by the broken line in FIG. 9(A)). However, the batted ball flowing down the gaming section 3 does not affect the ball detector and hits the pocket 37.

It is possible to import it to the rear of the .

[0036] In the embodiment shown in the drawings, a solenoid is normally built into the electric accessory 8, but this solenoid may be an external type that is attached to a game board or the like and communicated via a link mechanism or the like. You can also do it.

According to the normal electric accessory 8 as described above, it is possible to distinguish between balls that enter the ball by passing through the ball detector and balls that enter the ball without passing through the ball detector. If the ball detector is provided with a function as a starting port, the starting port and a so-called electric tulip can be integrated. Therefore, the installation space on the game board 1 can be reduced, the processing of winning balls on the back side of the game board 1, the installation and wiring of the ball detector can be simplified, and installation work, maintenance and inspection, etc. can be facilitated.
High practical value. Moreover, even if the number of prize balls for the starting hole and the number of prize balls for the general winning hole are different, it is possible to correspond to each winning.

Although the present invention has been described above with reference to the embodiments shown in the drawings, the present invention is not limited to the above-described embodiments, and can be carried out as appropriate without changing the configurations set forth in the claims. For example, the actuating means may not be provided within the electric accessory but may be provided independently. The present invention also provides a pachinko machine having a game state converting means that creates a state advantageous to the player by repeatedly opening and closing movable wings when a predetermined condition is met, and It can be applied to a pachinko machine having a game state converting means that opens a big prize opening when a ball enters the ball.

[0039]

Effects of the Invention According to the pachinko machine according to the present invention, the operating means of the movable winning device and the starting means of the game state converting means are arranged on a series of ball paths. There is a possibility that these two factors may work together, and the value of a single batted ball can be significantly increased. In addition, since a series of ball paths are formed, if the player can concentrate the ball in the direction of this ball path, both the actuating means and the starting means can be turned into an advantageous state for the player. It becomes possible to aim, and it is easier to plan a game strategy. On the other hand, from a gaming parlor's point of view, it is sufficient to ensure that the balls are scattered appropriately on the surface of the gaming board, making it easier to adjust the nails and manage the game.
