Description

Description: TECHNICAL FIELD The present invention relates to a pachinko machine, and more particularly, when a specific winning device provided in a game section receives a hit ball, the movable member is in a state in which the hit ball is easily received. A so-called special game mode in which the ball is converted once or several times for a short time, and when another hit ball enters the special winning opening in this state, the movable member is continuously converted into a state in which the hit ball is easily received in a certain manner. The present invention relates to a pachinko machine equipped with a variable winning device that can generate a.

[Conventional technology]

Recently, under certain conditions as described above, a pachinko machine equipped with a variable prize winning device that can continuously and repeatedly generate a special game mode in which a ball is easily accepted based on a ball hitting a special winning opening is provided. Variously developed, it has been well received by players.

The special game mode in a conventional pachinko machine equipped with a variable winning device is generally as follows. That is, when the movable member wins the special winning opening while the movable member is converting into a state in which the movable member is easily received, the first one cycle of the special game mode in which the movable member opens and closes continuously 18 times occurs first. When the ball hits the special winning opening again during the cycle, the first cycle ends at that point regardless of the remaining 18 times of opening / closing operations, and the next 1
The cycle, that is, the second cycle of the special game mode in which the movable member again opens and closes 18 times in a row has started. And, the number of times the cycle is generated in such a special game mode is, for example, up to 8 times. In addition, the maximum number of winning balls in each cycle is limited to 10, for example, and if the maximum number of winning balls is reached without hitting the special winning opening, the movable members in the cycle are continuously opened and closed. Regardless of the remaining number of times of opening and closing and the remaining number of cycles among the maximum number of times of cycle occurrence of 8 times, the special game mode is finished at that time.

[Problems and Objectives to be Solved by the Present Invention]

As mentioned above, the special game mode on the conventional pachinko machine is:
The condition of one cycle of the special game mode given to the player by winning the special winning opening, that is, both the number of continuous opening and closing of the movable member (18 times) and the maximum number of winning balls (10) are fixed. Since it is fixed and this is simply repeated in every cycle, even if a special game mode occurs, the game tends to be monotonous, and the interest of the game is lacking.

Therefore, according to the present invention, of the game conditions in one cycle of the special game mode generated based on the winning of a hit ball at the special winning opening, even if the number of continuous opening and closing of the movable member is fixed as in the conventional case, For example, by changing the fixed maximum number of prize balls, such as 10 randomly, every game cycle, and by making the maximum number of prize balls known to the player, It is an object of the present invention to provide a pachinko machine in which the game conditions in each cycle do not simply repeat the same condition but change the game and improve the interest of the game.

[Means for solving problems]

The present invention has been devised in view of the above points, and a plurality of cycles in which a large number of product balls are discharged to a player with a certain probability based on winning of a specific winning device provided in a game section. A pachinko machine capable of generating a special game mode consisting of a pachinko machine, wherein the pachinko machine has a movable member axially attached to the surface of a base, a first state in which the movable member is in contact with the movable member, and a disadvantageous state for the player, An electric drive source for converting into an advantageous second state, a plurality of general winning openings for winning the hit ball received by the movable member and a single special winning opening are arranged in a circle on the rotating body. A variable winning device having a rotating winning means and a rotation driving means for driving any one of the winning openings to sequentially appear, and a hit ball received by the movable member is a special winning opening of the rotating winning means. The above special according to winning When a technique occurs, one of the general winning openings corresponding to the read value is selectively made to appear from the plurality of general winning openings based on the read value from the random number data table, and the rotary winning means is operated. And a control means for controlling the rotation driving means so as to temporarily stop the rotation driving by moving the winning opening each time a hit ball is won, and the general appearance that appears based on the read value from the random number data table. Each time a hit ball is won from the prize hole, it is sequentially driven to rotate and the maximum number of balls that can be won in that cycle is randomly determined in each cycle, which is defined by the number of prize holes up to the special prize hole. A pachinko machine characterized by the above is provided.

〔Example〕

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 shows the outline of a pachinko machine according to the present invention. As shown in the figure, the pachinko machine main body 1 has a ball supply tray 3, a ball striking device 4, a saucer 5 and the like on the surface of a frame-shaped front frame 2, and the window portion of the front frame 2 is closed from the rear side. On the surface of the provided game board 6, there is a game section 8 surrounded by a guide rail 7 made of a strip-shaped metal plate for restricting a passing area of a hit ball. On the front side of the game section 8, a large number of obstacle nails 9 (only so-called nails are shown), a variable winning device 10 which has a game function and is a feature of the present embodiment, and a game of the variable winning device 10 are started. It is equipped with the first specific winning device 11, 11 and the second specific winning device 12 etc. which are involved, and on the back side thereof, a prize ball processing discharging device (not shown) for processing the winning balls and discharging the prize balls, It is provided between the specific winning devices 11 and 12 and the variable winning device 10, and starts the game of the variable winning device 10 based on the winning of the specific winning device, and controls the changing operation of the variable winning device based on the game result. It is provided with the control device 13 and the like involved.

When the player elastically shoots one pachinko ball in the ball supply tray 3 with the one-shot launch device 4, the hit ball is guided into the game unit 8 by the guide rail 7. The hitting ball guided into the game section 8 collides with a large number of obstacle nails 9 and flows down on the game board surface,
In some cases, it may enter into any prize hole or prize device in the middle of flowing down, or in some cases may not enter into any prize hole or prize device. In the latter case, it was opened at the lowest position of the game section 9. It is discharged and collected from the out port 14 as an out ball to the back side of the game board 6. When the hit ball flowing down the game board surface wins the first specific winning device 11, 11 or the second specific winning device 12, the first specific winning detector 15 provided facing the flow path of each specific winning device 11, 12. , 15, and the second specific winning detector 16 detect the winning of the hit ball, and send the detection signal to the control device 13 provided on the back surface of the game board 6. The control device 13 receives a detection signal from the specific prize detector 15 or 16 and converts the movable member of the variable prize device 10 described later from a first state in which no hit ball is accepted into a second state in which a hit ball is easily accepted. Issue a control signal for.

In the illustrated embodiment, when the ball hits the first specific winning device 11 and the first specific winning detector 15 outputs a detection signal,
In response to this, the control device 13 causes the variable winning device 10 to change the movable member from the first state in which the hit ball is not accepted at all to the second state in which the hit ball is easily accepted only once for a predetermined time (for example, 0.5 seconds). Give a signal. On the other hand, generally, due to the nails that are planted in the surrounding area, or the arrangement positional relationship,
When the second specific winning device 12 adjusted so that it is harder to hit the ball than the first specific winning device 11 is hit, and the second specific winning detector 16 outputs a detection signal, a control device
13 is correspondingly longer than the predetermined time, for example
A signal for converting from the first state to the second state is output twice consecutively for 0.8 seconds with a time interval of 0.8 seconds in the middle, for example. It goes without saying that the conversion mode of the variable winning apparatus based on the winning of each specific winning apparatus, that is, the number of times the movable member is converted, the conversion duration time, etc. are not limited to those described above.

Under the control of the control device 13, when the movable member of the variable winning device 10, which is a feature of this embodiment described in detail below, is opened in the second state where it is easy to receive a hit ball, it is received in the variable winning device 10. The hit game ball enters the special winning opening and is detected, so that a special game mode is generated.

Next, a specific configuration of the variable winning device 10 used in the pachinko machine according to the embodiment of the present invention will be described.

2 and 3 are a front view and a perspective view, respectively, of the variable winning a prize device 10, which is a feature of this embodiment.

This variable winning device 10 provides a variable winning area in the central part of the game part 8 by fixing the base 30 to a large mounting hole formed in the game board 6 with screws.
Below the inside of the variable winning device 10, a plurality of general winning openings and a single special winning opening, which are the features of this embodiment, are arranged in a circle on a rotating body. The winning means 34 is provided so that any one of the winning openings sequentially appears on the front part of the device. The details of the winning means 34 will be described later. Movable members 35a, 35b are rotatably supported by pivots 36a, 36b on both sides of the winning means 34. The pivots 36a, 36b extend through the base 30 to the rear and communicate with an electric drive source D having an electromagnetic solenoid, which will be described later, as a main component. Foundation
On top of 30, a winning opening 37 is opened, and an upper surrounding wall 38 whose upper surface also serves as a ball guiding plate to the winning opening 37 is integrally formed. On the front surface of the surrounding wall 38, a decoration plate 39 to which decoration such as coloring is applied is fixed. Side surrounding walls 40, 40 are provided below both ends of the upper surrounding wall 38. The side surrounding walls 40, 40 are preferably made of a colored or colorless transparent plastic molded member having a light diffusing surface, and light emitted from various lighting devices provided inside the variable winning device is inside the device. It is desirable not only to dissipate outside the device. In the initial state, the movable members 35a, 35b are in a substantially upright state (first state) as shown by the solid line in FIG. 2 and FIG. 3, but the movable members 35a, 35b are arranged at the rear of the variable winning device 10 by the control device 13 on the back side of the game board. When an electric drive source D, which will be described later, is energized, the movable members 35a and 35b rotate symmetrically about the pivots 36a and 36b by a predetermined angle, and the open state as shown by the one-dot chain line in FIG. (Second state). The movable members 35a and 35b when in the first state, together with the upper surrounding wall 38 and the side surrounding walls 40 and 40 located at the information, the hit ball flowing down the game board surface 6 is in the variable winning device 10. Therefore, the winning means 34
Will be blocked. On the other hand, when the movable members 35a, 35b are in the second state due to the urging of the electric drive source D, this is a state in which the ball hitting the game board surface is just received from below, and therefore the ball has a very high probability of being hit. It will flow into the variable winning device 10. The inflowing pachinko ball wins either the general prize opening or the special prize opening of the winning means 34, at the prize opening appearing in front of the device at that time.

The variable winning a prize device 10 of the illustrated embodiment is configured by imitating the whole or particularly a part located inside thereof as a robot, and the movable members 35a and 35b described above correspond to the hands of the robot, The front side is provided with a suitable pattern and coloring. A part 42 corresponding to the face of the robot and a part 44 corresponding to the ears are a box frame 50 provided on the back side of the base 30.
A drive means (corresponding to reference numeral 60 in FIG. 4) housed in the upper part of the inside can swing and rotate.
In addition, a colored light-transmitting plate is provided at any part of the robot (a part such as eyes and chest), and it is illuminated with a small light bulb from the back side.
A variable prize winning device 10 is provided by providing an illumination device such as a light emitting diode.
The whole device is made highly decorative by lighting or blinking these in accordance with the conversion mode and the like. The drive mechanism for driving the neck of the robot and the like by the drive means 60, the electric decoration device, and the like are well known, and are not the gist of the present invention, so a detailed description thereof will be omitted.

Next, referring to FIG. 4 and FIG. 5, a variable winning device
A method of connecting the movable members 35a and 35b of FIG. 10, the base 30, and the electric drive source D provided at the rear of the box frame 50 will be described.

Project to. A motion converting member 60a is fixed to the shaft end of the support shaft 36a, and the other shaft 61a is loosely fitted in a long hole 67a of an operating plate 66a fixed to a rod 65a of an electromagnetic solenoid 64a. Electromagnetic solenoid 64
When a is deenergized, the rod 65a of the electromagnetic solenoid 64a moves the operating plate 66a due to the extension force of the coil spring 68a and the tensile force of the coil spring 69a locked to the operating plate 66a.
Has been pulled up to a position where the upper end of the abuts the stopper 63a and stops. At this time, the movable member 35a is held in a substantially upright state so as to prevent a hit ball from flowing into the winning device 10.

On the other hand, when the electromagnetic solenoid 64a is energized, the rod 65a and the operating plate 66a of the electromagnetic solenoid 64a are pulled down by the coil springs 68a and 69a against the stretching force and the pulling force, and thus the long hole of the operating plate 66a. The motion converting member a, whose shaft 61a is loosely fitted in 67a, rotates counterclockwise about the pivot 36a, and accordingly the movable member 35a opens so as to allow inflow of a hit ball into the winning device 10. . Although only the movable member 35a on the right side when viewed from the front of the variable winning device 10 has been described above, the movable member 35b on the left side, which is paired with this, is
The structure is symmetrical to the movable member 35a and the operation is exactly the same, so the description is omitted. Further, in the embodiment, the case where different electromagnetic solenoids 64a and 64b are provided for the pair of left and right movable members 35a and 35b is shown, but it is also possible to provide a single electromagnetic solenoid in common. .

Next, a specific configuration of the winning means 34 will be described with reference to FIGS. 6A and 6B. 6A and 6B show the winning means.
FIG. 34 is an exploded perspective view of the 34 main structures as seen from diagonally above and diagonally below, respectively.

In the figure, reference numeral 72 is a rotating body, which is the greatest feature of the variable winning device 10 of the present embodiment, and has a double structure of an outer peripheral portion 73 and an inner peripheral portion 74. By sticking a sticker or directly coloring, a total of 10 character displays 77 are displayed, including continuous numerical indications "01" to "09" corresponding to general winning openings and special indication "☆" corresponding to special winning openings. It has been made for one round. The bottom of the rotating body 72 and the outer peripheral portion 73

In addition, at the lowermost part of the outer surface of the outer peripheral portion 73, the winning means driving motor 70
A gear 76 for meshing with the gear 71 fixed to the drive shaft (see FIG. 4) is provided, and the rotating body 72 rotates in the direction of arrow A by the operation of the drive motor 70. The drive motor
Reference numeral 70 denotes a pulse motor, which is driven so that the numeral display "01" to "09" and the special display "☆" mark of the rotating body 72 advance exactly by one based on the rotation amount of the drive shaft by one pulse. The gear fixed to the rotary shaft of the drive motor 70 so that the rotor 72 rotates in the direction of arrow A by exactly 36 ° (= 360 ° / 10) every time one pulse is applied from the control device 13 to the motor 70 for drive. 71 and the number of teeth of the gear 76 of the rotating body 72 are set.

Reference numeral 80 is a lower substrate, and a shaft 81 for rotatably pivoting the rotating body 72 upward is provided substantially at the center thereof. Further, an arc-shaped sphere lead-out hole 82 is provided in a portion in front of the shaft 81 and corresponding to the sphere passage hole 75 of the rotating body 72.

The reference numeral 90 designates an upper substrate, and a bearing portion 91 for receiving the shaft 81 of the lower substrate 80 on which the rotating body 72 is axially mounted is provided at the substantially rear center thereof.
Is provided, and a notch 92 for allowing the pachinko ball 100 to pass is provided in the center of the front part. The upper substrate 90 is such that, after the rotor 72 is attached to the shaft 81 of the lower substrate 80, the upper substrate 90 covers the rotor 72 except a part of the front side of the rotor 72.
Is screwed to a boss 83 protruding from the rear. The upper and lower substrates 90 and 80 and the rotating body 7 assembled in this way
As shown in FIG. 3 and FIG. 4, the main structure of the winning means 34 composed of 2 is the pivots 36a, 3 of the movable members 35a, 35b.
From the vicinity of 6b, the end faces of the ball guide plate 105, in which the rolling surfaces of the hit ball are inclined downward and slightly forward, that is, the ball outlet 1
The upper substrate 90 is accommodated in the box frame 50 located at the rear of the base 30, with the notch 92 of the upper substrate 90 aligned with 10.

The ball guide plate 105 has the following device for the purpose of preventing the winning balls that are generated simultaneously or successively from being stagnated (clogging) at the ball outlet 110. That is, as shown in FIG. 1, by slightly differentiating the inclination angle of the left ball guide plate 105a toward the ball outlet 110 and the inclination angle of the right ball guide plate 105, the ball outlet A step d is provided at 110. In the case of the illustrated embodiment, the inclination angle of the left ball guide plate 105a is slightly larger than that of the right ball guide plate 105b, and a step d is formed at the end thereof, so that both movable members 35a and 35b simultaneously operate. Even if the two hit balls are guided to the ball outlet 110, the hit ball coming from the left side is sent out from the ball outlet 110 toward the main structure of the winning means 34 at the same time by the step d. Alternatively, the winning balls that are continuously generated do not stay (ball jam) at the ball outlet 110.

Next, referring again to FIGS. 6A and 6B, the upper substrate
Various detection means provided on 90 and the lower substrate 80 will be described.

The detection means included in the variable winning a prize device 10 of the present embodiment,
(1) A winning ball detector S1 that detects the occurrence of winning balls to the winning means 34 of the winning device 10, (2) a rotation detector S2 that detects the rotation state and position of the rotating body 72, and (3 ) Three special position detectors S3 that detect the state where the special display "☆" of the character display 77 on the rotating body 72 is located just in front of the device, that is, the special winning opening has appeared. And
In the illustrated embodiment, each of the detectors described above employs an optical detector in which a light emitting element and a light receiving element are arranged so as to face each other.

First, the winning ball detector S1 that detects the occurrence of winning balls on the winning means 34 of the winning device 10 will be described. Prize Ball Detector S1
Is composed of a combination of a light emitting portion S1a and a light receiving portion S1b facing the light emitting portion S1a with a gap of several millimeters, and both are fixed by using an appropriate pointing member 84 fixed to the back side of the lower substrate 80.
A support shaft 85 is also fixed to the support member 84, and a swing member 86 is inserted into the support shaft 85 to swingably support the support shaft 85. A ball lead-out hole is provided on one side orthogonal to the axis of the swing member 86.
A ball receiving plate 87 facing the 82 is formed, and on the other side, a shielding plate 88 that moves in and out of the gap portion between the light emitting portion S1a and the light receiving portion S1b by the swinging action is formed. The swing member 86 is a support shaft
Since the shielding plate 88 side is balanced around the 85 so as to be slightly heavier than the ball receiving plate 87 side, in the normal state, the ball receiving plate 87 is slightly above the substrate 80 through the ball lead-out hole 82. The protruding position is set, and the shielding plate 88 is set at the position where the shielding plate 88 is set out of the gap between the light emitting section S1a and the light receiving section S1b. Therefore, in this state, the light constantly emitted from the light emitting section S1a is directly received by the light receiving section S1b. Next, when the pachinko ball 100 passes in front of the notch 92 of the upper substrate 90 and further passes through one of the ball passage holes 75 of the rotating body 72 and then drops onto the ball receiving plate 87, the pachinko ball 100 The sphere 100 rotates the swinging member 86 counterclockwise in the drawing, and the shielding plate 88 accordingly causes the light emitting portion S1a and the light receiving portion S1b.
It will enter the gap between and. As a result, the light emitted from the light emitting section S1a and received by the light receiving section S1b is blocked by the interposition of the shielding plate 88. The pachinko ball 100 that dropped onto the ball receiving plate 87 and pushed it down is the winning means 34.
It goes without saying that the balls are discharged to the outside of the prize winning device 10 for the prize ball discharging process through an appropriate guide gutter provided below. At the same time as the pachinko ball is ejected, the swinging member 86 rotates clockwise due to its own balance, the ball receiving plate 87 again faces the ball outlet 82, and the shielding plate 88 leaves the gap between the light emitting and light receiving portions. Becomes In response to this, the light from the light emitting section S1a returns to the initial state in which it is received by the light receiving section S1b again. In this way, the winning of the hit ball to the winning means 34 is achieved by the winning ball detector S1.
It is understood that the light can be detected based on the interruption of the incident light on the light receiving portion S1b.

Next, the configuration of the rotation detector S2 for detecting the rotation state and the position of the rotating body 72 will be described. Rotation detector S2
Is a light emitting portion S2a of the infrared light emitting diode arranged upward on the lower substrate 80 and a light receiving portion S2b of the phototransistor or photodiode arranged downward on the upper substrate 90.
Infrared rays emitted from the light emitting section S2a are received by the light receiving section S2b after passing through the slits 79 provided inside the sphere passing holes 75 of the rotating body 72 corresponding to each of them. Has become. The slit 79 is provided only when the numerical indications “01” to “09” and the special indication “☆” on the outer peripheral surface of the rotating body 72 are directly in front of the device.
Since the light is emitted from the light-receiving portion S2b, the rotation detector S2 determines the following based on the incident state of the light emitted from the light-emitting portion S2a on the light-receiving portion S2b. Can be detected. That is, in a state in which the incidence of light to the light receiving section S2b is blocked by the wall between a certain slit 79 and the adjacent slit 79, a certain character display located directly in front of the device shifts to the next character display. Rotating body 72 to
On the contrary, in the state where the light from the light emitting portion S2a is received by the light receiving portion S2b through the slit 79, any one of the ten character displays described above is positioned in front of the device. Then, it is possible to detect that the prize hole is provided.

Next, a specific position detector for detecting that the special display "☆" of the characters in the character display 77 on the rotating body 72 is located just in front of the device and provides the special winning opening. The configuration of S3 will be described. The specific position detector S3 is made up of a combination of a light emitting portion S3a and a light receiving portion S3b which faces the light emitting portion S3a with a gap of several millimeters, like the above-mentioned winning ball detector S1, and inserts the rotating body 72 in the middle. When the upper substrate 90 is screwed to the lower substrate 80 and the main structure of the winning means 34 is assembled, the light emitting unit S3
In the gap between a and the light receiving part S3b, the outer peripheral portion 73 of the rotating body 72 is
Are provided so that they can be placed on the lower surface of the upper substrate 90. Since the outer peripheral portion 73 intervenes in the gap between the light emitting portion and the light receiving portion, the light constantly emitted from the light emitting portion S3a is blocked from entering the light receiving portion S3b. Is provided with a slit 78 only at one position, and the light from the light emitting unit S3a receives the light from the light receiving unit S3b only at this position.
Can receive light. Slit 78,
Since the light emitting section S3a and the light receiving section S3b face each other when the special display "☆" of the character display 77 is located directly in front of the device, the light from the light emitting section S3a is received by the light receiving section S3a.
When 3b receives light, it can detect that the special display "☆" is located just in front of the device. The specific position detector S3 and the light receiving portion S2b of the rotation detector S2 described above.
After being attached once to the printed circuit board 93, the printed circuit board 93 and the printed circuit board 93 are respectively projected to the back side (lower side) of the circuit board 90 through the openings provided in the upper circuit board 90.
Are fixed by being screwed onto the surface (upper side) of the upper substrate 90.

In the case of the illustrated embodiment, all the optical detectors are adopted as the various detectors S1, S2, S3, but all or a part of the optical detectors are used, for example, a micro switch is used. Of course, it can be replaced with a mechanical detector or a magnetic detector such as a proximity switch.

The variable winning device 10 according to the present embodiment is configured as described above, and its electric drive source D (electromagnetic solenoids 64a, 64).
b), the driving motor 70 of the winning means 34 and the detectors S1, S2, S
3 is for the control device 13 to which the first and second specific winning detectors 15 and 16 related to the first and second specific winning devices 11 and 12 are connected,

As described, the control device 13 is involved in the start of the game of the variable winning device 10 based on the winning of the hit ball to the specific winning devices 11 and 12, and the control of the changing operation of the variable winning device 10 based on the game result. , Is arranged on the back side of the game board 6 as shown in FIG.

The control device 13 is a microprocessor (central processing unit) 13
1, a memory (storage device) 132, and an interface (input / output signal processing device) 133. The control device 13 may have a discrete configuration centered on a logic circuit element, but will be described in detail below for reasons such as ease of handling various game control modes by chip replacement and suitability for mass production. It can be said that it is preferable to use a microprocessor configuration that makes a detailed description. The interface 133 of the control device 13 is provided with the first specific prize detectors 15, 15 and the second specific prize detector 16 from the first specific prize detectors 11, 11 and the second specific prize device 12 along with the winning of the hit ball. The winning detection signal is input and the detection signals from the winning ball detector S1, the rotation detector S2 and the specific position detector S3 in the variable winning device 10 are also input. From the interface 133, a signal for controlling the operation of the winning means driving motor 70 related to the winning means 34 of the variable winning device 10, and the movable member.
A signal for controlling the operation of the electric drive source D related to 35a, 35b is output. In addition to these signals from the interface 133, in addition to these signals, lighting control signals to various lighting devices provided inside and outside the variable winning apparatus 10, in the case of the illustrated embodiment, in relation to the face 42 and the ears 44 of the robot. Signals for controlling the swinging and rotating movements thereof are also output.

Hereinafter, an example of a control mode of the variable winning device 10 by the control device 13 will be described.

Simultaneously with turning on the power to the pachinko machine 1, the winning means driving motor 70 of the variable winning device 10 starts to rotate by receiving pulses continuously sent from the interface 133 of the control device 13. In response to this, the rotating body 72 having the character display 77 on the peripheral surface rotates in one direction, that is, in the direction indicated by the arrow A in FIG. 6, and the display character positioned directly in front of the device is "☆",
It constantly changes from one to the next while circulating in the order of "01" to "09", and enters a winning waiting state waiting for winning a hit ball to the specific winning device 11 or 12. As described above, among the character displays 77, the numerical displays “01” to “09” correspond to the general winning openings, and the special display “☆” corresponds to the special winning openings. In the winning standby state, since the movable members 35a and 35b are controlled to be in a substantially upright closed state, there is no possibility that a hit ball will win the winning opening corresponding to each character display. The rotation speed of the rotating body 72 can be adjusted by changing the pulse interval of the intermittent pulses continuously emitted by the interface 133.

In the above-mentioned winning standby state, a hit ball is won in the specific winning device 11 or 12, and this is detected by the specific winning detector 15 or 16, and the detection signal thereof is the interface 133 of the control device 13.
Is input to the electric drive source D of the variable winning apparatus 10, the drive signal is transmitted from the interface 133.
The electric drive source D moves the movable members 35a, 35 in response to the drive signal.
Open b once or twice so that it is easy to accept the ball. In the illustrated embodiment, the movable member is opened once when the first specific winning device 11 is won and twice when the second specific winning device 12 is won. Movable members 35a, 35
When the hit ball enters between the movable members, that is, inside the winning device 10 within a short time when b is opened, the hit ball reaches the ball outlet 110 via the ball guide plate 105, and is in the rotating state of the rotating body 72. Of the character displays 77, the player will win any one of the winning openings corresponding to the numerical displays “01” to “09” or the special display “☆” located right in front of the device. If the ball hits continuously between the movable members when the movable members 35a, 35b are opened, the rotation of the rotating body 72 causes the winning holes to appear in front of the device one after another. Will be awarded one by one. From winning a prize to the specific winning device 11 or 12, until a hit ball enters the variable winning device 10 during the opening / closing operation of the movable member based on the winning, and the hit ball wins any prize hole corresponding to the character display 77. This process is a so-called "game" in which there is a possibility of occurrence of a special game mode with a probability of 1/10 in the pachinko machine of the present application. The "game" often ends because the ball does not enter the variable winning device 10 while the movable member is being opened for a very short time. 01 "~" 0
The case where the ball is hit in the general winning opening corresponding to 9 "and the game is ended, and the case where the game is ended in the special winning opening corresponding to the special display" ☆ "are separately described.

First, when a hit ball is won in any of the general winning openings corresponding to the numerical indications “01” to “09” and the game is ended, the hit ball is detected by the winning ball detector S1 and the detection signal is detected by the interface 133. Sent to. Based on this detection signal, only the lighting control signal is output from the control device 13 (interface 133) to the electric decoration device provided inside and outside the variable winning device 10, and the winning means driving motor 70 and the electric device. Since no special control signal is sent to the dynamic drive source D, the rotating body 72 continues the rotary motion as before the hit ball wins, and the movable members 35a and 35b are further opened in association with this win. There is no such thing, and the game immediately returns to the winning prize waiting state described above. It is needless to say that a normal prize ball (for example, 11 or 13 balls) is paid out to the player from the prize ball processing and discharging device based on the hit ball that is won in the general winning opening.

Next, a case will be described in which the hit ball wins the special winning opening corresponding to the special display "☆" and the game ends. in this case,
In addition to the detection signal from the winning ball detector S1 based on the winning of the hit ball, a specific position that detects that the winning of the hit ball has occurred at the special winning opening corresponding to the special display "☆" located directly in front of the device. The detection signal from the detector S3 is simultaneously input to the interface 133. Memory 1 of controller 13
In the 32, the detection signal from the winning ball detector S1 and the detection signal from the specific position detector S3 are simultaneously interfaced 133.
It is programmed so that the special game mode occurs only when it is input to. Due to the occurrence of this special game mode, the control device 13 controls the electric drive source D and the winning means driving motor 70 as follows. That is, the control device 13
Simultaneously with the occurrence of the special game mode, the transmission of the pulse from the interface 133 to the winning means driving motor 70 is cut off, and the rotary motion of the rotating body 72 is once interrupted. Therefore, at the time of this stop, the character display located directly in front of the device is displayed.
The display character of 77 is a special display "☆". Then the control device 13
Reads a certain numerical value from a random number data table stored in advance in a ROM (read-only memory) in the internal memory 132, and based on the read numerical value, the winning means driving motor 70 from the interface 133.
One of the 9 pulse numbers corresponding to the pulse numbers "1" to "9" is transmitted toward the. Interface 133
Assuming that the number of pulses “3” (corresponding to three pulses) is transmitted from the drive motor 70 to the drive motor 70, the rotating body 72 uses the special indication “☆” as a reference based on the position detected by the specific position detector S3. Then, the position is rotated by an amount corresponding to three pulses. That is, the character display 77 on the rotating body 72 is rotated until the numerical display is "03", and at this position, it is stopped again. The confirmation that the numerical display "03" is located in front of the device is to confirm that the special position "☆" is located in front of the special position detector S3. This is performed by inputting a detection signal from the rotational position detector S2 to the interface 133 of the control device 13. Simultaneously with the stop of the winning means driving motor 70, the electromagnetic solenoids 64a and 64b are directed from the interface 133 of the control device 13 toward the electric drive source D, for example.
A drive signal for driving 18 times at 0.8 second intervals is sent. In response to this, the movable members 35a, 35b repeat the opening / closing operation 18 times in succession, and the hit ball that has entered the winning device 10 during that time is detected by the winning ball detector S1 each time a prize is won, and the detection signal is detected by the interface 133. Sent to. Further, each time a detection signal is received from the winning ball detector S1 from the interface 133, one driving pulse is sent to the winning means driving motor 70. As a result, the numerical display "03"
The number display that started with "04", "0"
It increases to 5 "... and when there is a seventh prize during 18 consecutive opening and closing movements of the movable member, it returns to the special mark" ☆ "corresponding to the special winning opening. , The first game cycle of the special game mode is completed.Note that the controller 13 rotates from the position where the rotor 72 is rotated and stopped again based on the numerical value read from the random number data table. The number of characters displayed up to the special display "☆" is determined as the maximum number of winning balls in a game cycle with a special game mode, that is, in the above case starting from the numerical display "03" based on the read value of the random number data table. The maximum number of winning balls in the first game cycle of the special game mode is determined to be 7.

The special mark "☆" that reappeared due to the winning of the 7th hit ball is in the state of being stopped until the next winning, and the movable member is normally repeating 18 times of continuous opening and closing operations. Therefore, there is a high possibility that the next hit ball will enter the special winning opening corresponding to this special display "☆", and it can be said that the occurrence of the second cycle of the special game mode is extremely easy. As described above, in the present invention, the winning probability to the special winning opening has conventionally been determined only by the randomness of the inflow ball, whereas the maximum winning ball in consideration of the balance of the profit between the player and the game shop. By changing the small number irregularly within the range of several tens, it is easy to update the cycle while balancing profits. It should be noted that due to a long interruption of the blasting operation by the player on the way or the immaturity of the game technology, there are only 6 or less hit balls during the open / close operation of the movable member 18 times in succession, and the position of the special display "☆" If you don't get to
If the special display "☆" is reached by the winning of the first hit ball, but there is no further winning in that state, that is, there is no eighth winning, the special game mode ends at this point, that is, the first cycle. When the movable member is closed, the rotating body 72 continuously returns to the winning standby state in which the rotating body 72 continuously rotates.

When the first one cycle of the special game mode is finished and the special display "☆" is returned and the rotating body 72 is stopped, the next hit ball, that is, the eighth hit ball is won, and the interface 133 is again displayed. The detection signal from the winning ball detector S1 and the detection signal from the specific position detector S3 are simultaneously input, and the second cycle of the special game mode is started. That is,
The control device 13 again reads an arbitrary numerical value from the random number data table stored in the ROM of the memory 132, and determines the pulse number corresponding to any of the pulse numbers “1” to “9” based on this numerical value. It sends it to the winning means driving motor 70.
The rotating body 72 rotates according to the number of pulses, and the number of characters from the displayed character when it is stopped again to the special display "☆" is 1
It is determined as the maximum number of winning balls in the second game cycle, irrespective of the maximum number of winning balls. That is, the maximum number of winning balls in each cycle is irregularly determined each time in each cycle based on the numerical value read from the random number data table stored in the ROM in the memory 132 of the control device 13. The operation in the second cycle after the maximum number of winning balls is determined is the same as that in the first cycle, and the description thereof will be omitted. Then, in the third and subsequent cycles of the special game mode, the special display "☆" reappears when the number of winning balls in the previous cycle reaches the maximum number of winning balls in the cycle, and the winning of the next hit ball Will continue as long as there is.

Incidentally, the drive motor 60 and the various lighting devices that perform the swinging and rotating motions of the face 42 and the ears 44 of the robot, put a short interruption time at the same time as the occurrence of the special game mode and at each break of each game cycle accompanying it. In response to a control signal from the interface 133, it operates and lights up or blinks to call the attention of the player and to play a role on the game board surface of the pachinko machine.

Even in the pachinko machine of the present embodiment, the game cycle is infinitely continued due to the occurrence of the special game mode, and the same as the conventional pachinko machine for the purpose of limiting the prize balls extremely paid out to the player. Needless to say, it is possible to limit the number of cycle occurrences in the special game mode to, for example, up to 8 times.

Further, as the embodiment, the pair of movable members are arranged so as to face each other, and the movable member is converted into the first state in which the hit ball is not accepted and the second state in which the hit ball is easily accepted. The type of member is not limited to this,
For example, it may be a slide type or attacker type movable member.

〔The invention's effect〕

As described above in detail, according to the pachinko machine of the present invention, the special game mode including a plurality of cycles, which is given as an extremely advantageous state for the player based on the winning of the special winning opening, is conventionally fixed. The maximum number of balls that can be won in one cycle is reset to an irregular and variable value each time at the beginning of each cycle, so even after a special game mode has once occurred, the maximum prize can be won as before. The number of possible balls is not merely a fixed repetition of the game cycle, but the expectation of the player can be raised by giving different game conditions for each cycle.

In addition, the maximum number of balls that can be won in each cycle is equivalent to the fact that the player is guaranteed a prize in that cycle, so it is possible to win a special prize at an early stage as in the past. With this, the player can enjoy the game with peace of mind until the start of the next cycle without fear of shifting to the next cycle.

Furthermore, the rotating body of the variable winning apparatus does not always rotate, but moves to the next winning opening every time there is a winning in the winning opening that selectively appears during the occurrence of the special game mode, and stops. Therefore, it is possible to enjoy a variety of movements of the winning device on the game board surface.
