In such a gaming machine, a control device for controlling the electronic components of the game section is provided, so when an electrically driven one is adopted as the ball discharging device, the control device for controlling the game contents discharges the ball. A configuration that also controls the device is generally adopted.

Further, in the pachinko game machine, a game machine in which a game board is detachable from the main body of the game machine is mainly used. In such a gaming machine, it is possible to remove only the gaming board, so when a manufacturer develops a new model, the gaming shop replaces only the gaming board and replaces the so-called new pachinko machine at a low cost. In addition to being able to do it, even if a failure occurs, it is possible to replace only the game machine or perform maintenance and inspection with the game board removed,
There is an advantage that the maintenance and inspection work in the amusement store becomes easy.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional technology, since the control of the entire gaming machine is configured to be performed by one control device, in the case of exchanging with a new model gaming board In addition, since the game contents are often changed, it is necessary to replace the control device in addition to the game board, which causes a problem that extra expense is imposed on the game store. Also, if the control device is integrated, even if a failure occurs on the control system side of the game or if a failure occurs on the control system side of the ball discharging device, the entire control device must be replaced, so maintenance costs There is a problem that is high.

Further, in recent years, since the electronic parts that make up the game section have become diversified, the control device becomes large and the handling becomes complicated, and the wiring becomes complicated, so that other electronic parts can be replaced when the control device is replaced. There is also a problem that an accident such as damage or disconnection of wiring is likely to occur, and wiring is disconnected and connection is complicated due to replacement work.

Maintenance and inspection work can be easily performed, and the occurrence of failures is small and the cost for new replacement and maintenance is small. The object is to provide a ball game machine that can be completed.

[Means for Solving the Problem] In order to solve the above-mentioned problems, the present invention has a game board provided with at least a variable winning device in a game section detachably attached to a game machine main body, and On the back mechanism board, a ball ejecting device capable of ejecting a predetermined number of balls based on hit balls won in a winning part including the variable winning device, and a control device electrically controlling the variable winning device and the ball ejecting device. In a ball game machine provided with and, the control device is a first control device that electrically controls game control including the variable winning device, and a second control device that electrically controls discharge control of the ball discharging device. The control device is configured separately and mounted as separate control devices, and the second control device is detachably mounted at a predetermined position on the back mechanism board.

[Operation] According to the above means, when the game board of a new model is replaced, only the first control device needs to be replaced, and it is not necessary to replace the second control device that controls the ball discharging device or the like. , The cost for new replacement is low. Also,
If a failure occurs on the control system side of the game content, only the first control device is replaced, and if a failure occurs on the control system side of the ball discharging device, only the second control device is replaced. Therefore, the maintenance cost is low and it does not take time and effort.

Furthermore, each control device is compact and easy to handle, and it is only necessary to connect each control device with one or several wires, and each control device is integrated with two control wires. Compared to the case of the above, it is less and shorter, and it is less likely to damage other electronic parts or break the wiring when the control device is replaced, and the wiring is disconnected and connected easily during the replacement work. Will be able to do.

There is. When the tool 107 is inserted into the operating hole 106, the tip of the ball-removing lever 62b hits the lower side of the rotating plate 62, and together with the rotating plate 62, the ball-removing lever 62b resists the force of the spring 62a. It is designed to be rotated upward. This ball release lever 62
As shown in FIG. 10 and FIG. 11, the protruding portion 6 is provided with a downward restoring force by a spring 63a at the upper position of the tip of b.
The slide plate 63 having 3 faces, and the slide plate is installed on the support base 108 so as to be able to move up and down.
A guide rod 63b bent in a fixed shape is fixed to the. The guide rod 63b is bent in a shape so that when an excessive external force (force to push up the cam) is applied to the cam described later, the guide rod 63b bends and absorbs this force. This is because At the position where the tip of the guide rod 63b reaches, as shown in FIG. 9 and FIG. 11, the cam disk is attached to the shaft end 61b of the rotary shaft 61a supporting the switching gate 61.

A V-shaped cam protrusion 64c is provided, and the tip of the guide rod 63b is located in the cam groove 64b.

Further, as shown in FIG. 9, a first lock member 66 and a second lock member 67, which can be engaged with the lock pin 64a, are provided on the left and right front sides of the cam board 64, respectively.
Or supporting pillars 109a, 1 planted on one side of the hollow gutter 16
It is rotatably supported via 09b.

Then, as shown in FIG. 12 (A), the hook portion 66a of the first lock member 66 is engaged with the lock pin 64a, and the cam disc 64 is locked at the position rotated clockwise in FIG. As shown in Fig. 12 (B), the switching gate
61 is in a state of blocking the flow path to the ball extraction trough 16.

In this state, when the tip of the tool 107 is inserted into the operation hole 106, the ball removing lever 62b is rotated together with the rotating plate 62 in the counterclockwise direction in FIG. 12 (A). The ball lever 62
The slide plate 63 is pushed up by the tip of b while resisting the force of the spring 63a. The tip of the guide rod 63b fixed to the slide plate 63 hits the contact piece 66b side of the first lock member 66 to rotate the first lock member 66 clockwise to unlock the cam board 64. , The cam projection 64c hits the inclined portion on the right side in the figure to rotate the cam board 64 in the counterclockwise direction in the figure, and the lock pin 64a to the hook portion 6 of the second lock member 67.
The position where it can be engaged with 7a is reached. Where the tool 107
When the guide rod 63b is pulled out, the guide rod 63b returns downward, the hook portion 67a of the second lock member 67 is engaged with the lock pin 64a, and the cam disc 64 is locked so as not to rotate at that position (the thirteenth portion). (Figure (A))). At this time, the switching gate 61 is rotated counterclockwise as shown in FIG.
The flow path to the prize ball lead-out gutter 13 is closed by closing the flow path to. A pin provided on the top of the pin when it rotates
61b hits the ball removing switch 84 to turn it on, and as a result, the prize ball discharging device 20 is activated.

In this state, when the tool 107 is again inserted into the operation hole 106, the guide rod 63b rises in the same manner as described above, and this time the tip end thereof hits the contact piece 67b side of the second lock member 66 to lock it. The member 66 is rotated in the counterclockwise direction to unlock the lock pin 64a by the hook portion 66b of the member 66, and at the same time, hit the left inclined portion of the cam protrusion 64c to move the cam plate 64 to the first
In FIG. 3 (A), the lock pin 64a is rotated clockwise to engage the hook portion 66a of the first lock portion 67, and the cam disc 64 is locked so as not to rotate at the position and the twelfth lock pin 64a is locked. The state shown in FIG. At this time, the switching gate 61 also returns to the state in which the flow path to the ball removing trough 16 in FIG. 12B is closed. In this state, the tool 107 may be pulled out from the operation hole 106.

In the pachinko gaming machine of this embodiment, as shown in FIG. 20, if the ball-shedding switch 84 is turned on, about 1
After 5 seconds, the discharge solenoid 21 (see FIG. 4) in the prize ball discharge device 20 is excited, and if the shortage ball detector 93 detects that the storage tank 2 has become empty, 5 seconds have elapsed after the detection. The discharge solenoid is automatically turned off. As a result, when the staff switches the ball-removing gate 61, the prize ball discharging device 20 is automatically activated, and when the storage tank 2 is empty, the discharging is automatically stopped, so that wasteful empty discharging is prevented. The heating of the discharge solenoid is also avoided. Moreover, the ball shortage switch 93 is the storage tank 2
Since the discharge solenoid 21 is turned off after 5 seconds from the detection of the empty state, the balls existing in the guide trough 11 connecting the storage tank 2 and the prize ball discharging device 20 should be completely removed. You can

As described above, in this embodiment, even if the ball is removed, no ball remains between the ball removing device and the prize ball discharging device, and after the ball removing is finished, a part of the prize ball guideway or the prize ball discharging is performed again. The troublesome work for extracting the residual balls remaining in the device is unnecessary. In other words, in the conventional pachinko game machine using the ball sheath case, the ball removal gate was placed on the upstream side of the prize ball discharging device, so the ball remained in the middle even if the ball was removed. However, in this embodiment, since the ball removing device 60 is located on the downstream side of the prize ball discharging device, all balls can be removed and the data of the pachinko parlor can be accurately collected.

The lower end of the ball drain gutter 16 is joined with the out ball lead-out gutter 17 for guiding the out ball collected from the out hole 105, and is collected toward a collection gutter (not shown) arranged below the island facility of the pachinko parlor. It is designed to drain the ball.

Further, the back mechanism board 1 is a control device for electrically controlling the entire pachinko gaming machine, such as stopping the firing of hit balls according to detection signals from the prize ball discharging device 20 and the overflow detector 92, driving various display devices, and the like. There is provided a game content control device 210 for controlling the game operation based on signals from detectors incorporated in 200 and various variable winning devices on the front of the game board, variable display type auxiliary game devices and the like.

In the field of pachinko machines, in order to prevent game players from leaving due to monotonization of game contents, they are exchanged for new game boards with different game contents and design configurations, but in that case also excluding game boards The pachinko machine main unit and the back mechanism panel are almost the same. However, it is very uneconomical to replace such an invariant part together with the game board before reaching the end of its life.

In the above embodiment, when the game board is replaced, only the game board and its game content control device 210 need to be replaced. That is, the game content control device 210 is fixed to the back surface of the removable game board, and the prize ball discharge device 20, the prize ball processing device 40, and their control devices 200 are used for the spare ball storage tank 2 and various guide troughs 10. It is fixed to the back mechanism board 1 which is integrated with the main body of the gaming machine together with -17. Therefore, even when the game board is replaced, most of the main body and the back mechanism board remain and can be used continuously, which is very economical.

On the outer surface of the control device 200, prize ball number setting devices 81, 82 including dip switches and the like are attached in order to set the number of discharge balls in one discharging operation in the prize ball discharging device 20. In addition, at the upper part of the back mechanism panel 1, the collective shelves can be provided without operating the prize ball discharging device 20 at the time of hitting or failure.
A manual switch (hereinafter, referred to as a memory discharge switch) 83 for discharging the winning ball on 10 is provided. In other words, the memory ejection switch 83 gives a pseudo ejection end signal instead of the ejection sensor 25 in the prize ball ejection device 20 described later.

FIG. 3 shows the structure of the reserve ball storage tank 2, the guide gutter 11, and the prize ball discharging device 20, and the connection state thereof.

The storage tank 2 is mounted so as to be placed in a storage recess formed in the upper part of the back mechanism panel 1. Although not shown, an opening is formed at one end (the left end in the figure) of the bottom wall of the storage tank 2, and a guide gutter 11 is attached so as to face this opening. A tread plate is rotatably disposed on the bottom wall of the guide gutter 11, and the tread plate rises when there is no more reserve ball in the storage tank 2. The ball shortage detector 93 detects this and forms a ball replenishment request signal.

A flow dividing wall 11a is provided in the middle of the guide gutter 11, and separates and aligns a flowing ball into two lines. The ball seal 3 is suspended by a pin 3a on a support portion 11b formed on the upper part of the guide gutter 11,
The spheres that flow vertically over the guide gutter 11 are broken up and aligned. The ball seal 4 is rotatably supported by the support pieces 4a fixed to both sides of the guide trough 11 by pins 4b, and prevents the balls flowing down on the guide trough 11 from overlapping.

Further, a flow-down control member 7 rotatable around the pin 4b is provided in the guide gutter 11, preferably immediately before the prize ball discharging device 20. The bent piece at the front end of the flow-down control member 7 is divided into two pieces, and when the bent piece 7c, 7d is rotated as indicated by the broken line a in the figure, each bent piece 7c, 7d corresponds to the two guiding paths and is guided by the guide gutter 11. By entering into the long holes 11c, 11d formed in the upper wall of the guide wall, it is possible to prevent the ball from flowing down in the guide trough 11 and manually stop the supply to the prize ball discharging device 20.

As a result, the maintenance and inspection of the prize ball discharging device 20 and the replacement operation in the case of failure can be easily performed.

An operation piece 7b is provided on one side of the flow-down control member 7 so as to protrude laterally, so that the flow-down control member 7 can be easily rotated manually. Further, a spring 9 is provided between the operation piece 7b and the pin 8 provided on the side wall of the guide gutter 11.
Is suspended, and the flow-down control member 7 is
State can be maintained stably.

Further, a prize ball discharge device 20 having a flow-down path 30 is provided at the lower end of the guide gutter 11. In this case, a locking piece 11e is provided on the side of the gutter at the lower end of the guide gutter 11,
Further, a guide piece 30a projecting forward is provided at an upper portion and a lower portion of the start end of the flow-down path 30 on the prize ball discharging device side,
The guide gutter 11 and the flow-down path 30 can be connected to each other by the lock piece 11e.

4 to 6 show details of the prize ball discharging device 20.
The prize ball discharging device 20 comprises a downflow path 30, a downflow blocking member 22 that enters the downflow path 30 to control the downflow of a ball, and a solenoid 21 that is a driving means thereof.

The flow-down path 30 includes an alignment gutter 31 that is gently inclined,
The adjusting trough 33 extending substantially vertically downward from the lower end of the aligning gutter 31 and the adjusting section for changing the direction of the flowing ball at the connection portion between the aligning gutter 31 and the adjusting gutter 33 by about 90 degrees. 32, a guide gutter 34 extending obliquely downward about 45 degrees from the lower end of the flow control gutter 33, and a discharge gutter 35 extending substantially vertically downward from the end of the guide gutter 34. ing.

Near the boundary between the guide gutter 34 and the discharge gutter 35, a pair of support pieces 36 protrude from the outer wall of the flow-down path 30, and the support shaft 24 is suspended between the support pieces 36.

Further, two flow-down paths 30 are formed corresponding to the guide gutters 11, and a pair of fan-shaped flow-down preventing members 22 are rotatable about the support shaft 24 in correspondence with the two flow-down paths 30. It is installed. A pair of solenoids 21 are provided corresponding to the flow-down preventing members 22. Then, the tip end portion of the flow-down prevention member 22 enters through a slit provided in the inner wall portion of the flow-down path 30 and is projected into the guide gutter 34. The rear end of the falling-off preventing member 22 is connected to the leading end of the plunger 21a of the solenoid 21 via a link member 23, and the falling-off preventing member 22 moves around the support shaft 24 as the plunger 21a expands and contracts. The tip is reciprocated, and the leading end enters or retracts in the guide gutter 34. As a result, the flow of the balls is allowed or blocked, and a predetermined number of discharges are performed.

Further, the side wall of the guide gutter 34 swells to the outside, and the storage portion 37
The discharge ball detector 25, which is a transmission type optical sensor, is inserted into the storage portion 37.

The solenoid 21 is provided above the solenoid 21.
A connector 26 is provided for concentrating the lead wires drawn from the discharge ball detector 21 and the discharge ball detector 25 at one location, and for connecting the wiring for connecting to the control device 200 collectively from the front. ing. Then, the engaging portion 13a formed at the starting end of the prize ball outlet gutter 13 is engaged with the lower end of the flow-down path 30 for connection.

Furthermore, on the bottom surface of the alignment gutter 31 at the entrance of the downflow path 30,
As shown in FIG. 5, a conductive sheet 38 such as a metal plate is attached, and one end of the conductive sheet 38 is grounded to a frame or the like. As a result, the static electricity charged on the falling sphere can be released, and the discharge sphere detector 25 can be prevented from being destroyed by static electricity. In other words, it is possible to use a mechanical device such as a micro switch as the detector, but the micro switch has a slow recovery action, so if the sphere continuously flows down, it may remain on. It is also easy to cause chattering. In addition, contact failure is likely to occur due to long-term use. Therefore, the micro switch is not suitable as a detector for continuously detecting spheres like a prize ball discharging device. Therefore, in the above embodiment, an optical sensor is used as the ejected ball detector 25. However, since the optical sensor is formed of an IC, it is susceptible to static electricity, and furthermore, while the discharge sphere flows down in the guide gutter 11, the sensor is susceptible to static electricity due to friction with the gutter, and the static electricity tends to damage the sensor. There is an inconvenience. In the above embodiment, the inconvenience is avoided by discharging the conductive sheet 38 attached to the bottom surface of the alignment gutter 31. Further, by selecting the material of the conductive sheet 38, the frictional force between the ball and the gutter can be reduced and the flow of the ball can be made smooth.

Further, as shown in FIG. 3, slits 31a and 33a are provided on the upper wall of the flow control gutter 31 and the outer wall of the flow control gutter 33, which constitute the flow path of the prize ball discharging device 20, respectively. As a result, foreign matter and the like enter the downflow path and the prize ball discharge device
In the case where a ball is clogged in the inside of 20 or a smooth flow is obstructed, maintenance can be facilitated, for example, by inserting a tool such as a pin from the slit 31a or 33a to remove foreign matter. The slits 31a and 33a have a lid member 3 having a step 39a having substantially the same size as the slit.
9 is engaged and fixed to a screw or the like so as to be closed.

Next, the operation of the downflow path 30 and the downflow control device 20 configured as described above will be described in detail with reference to FIG.

The above-mentioned prize ball discharging device 20 is configured such that the flow-down preventing member 22 enters the guiding path 34 as shown by a solid line in FIG.
The pachinko balls B lined up in the downflow path 30 are the most advanced balls.
B ₁ is stopped by coming into contact with the outer peripheral surface of the flow-down prevention member 22. At this time, two balls B ₁ and B ₂ are housed in the guide trough 34, and _three balls B ₃ , B ₄ and B ₅ are housed in the adjusting trough 33. The dimensions of the diversion gutter 33 are determined.
Moreover, the uppermost ball B in the adjusting gutter 33 is a ball in the alignment gutter 31.
It is adapted to be pressed by B ₆ , B ₇ ... And come into contact with the tapered adjusting portion 32. The ball B ₅ receives a repulsive force from the adjusting unit 32 by being pressed toward the adjusting unit 32, and the repulsive force is transmitted to the ball B ₅ and the balls B ₄ , B ₃ ... Acts like pushing up. As a result, when the downflow prevention member 22 is retracted from inside the guide gutter 34 as shown by the broken line C in FIG. 6, the repulsive force from the adjusting portion 32 and the weight of the ball cause the flow control gutter 33 and the guide gutter 34 to move. The spheres B _{1 to} B ₅ start to flow down quickly.

When the spheres B _{1 to} B ₅ flow down, the spheres B ₆ , B ₇ ... In the alignment gutter 31 subsequently start to flow down. Then, at the exit of the alignment gutter 31, first, it collides with the adjusting section 32 to reduce the downflow speed, and the downflow direction is converted from the horizontal direction to the vertical direction by approximately 90 °, and the flow adjusting section 33
to go into. Here, since acceleration is performed by its own weight, a ball interval is secured between the ball and a subsequent ball that is decelerated by the adjustment unit 32. Therefore, for example, when the solenoid 21 is demagnetized when the ball B ₇ is detected, even if there is a delay in the operation of the flow-down preventing member 22, it is possible to prevent the flow-down before the ball B ₇ passes. By increasing the distance between the balls in this way, it becomes easy to control the downflow prevention member. However, to detect B ₇ prize balls to be discharged when the solenoid is switched to the OFF 21 is six.

Further, in the flow-down path 30, the center O ₅ of the sphere B ₅ located at the uppermost position of the flow control trough 32 is aligned in the alignment gutter 31 in a state where the flow-down prevention member 22 blocks the flow of the sphere. Sphere
The dimensions of the guide gutter 34 and the diversion gutter 33 are determined so as to be positioned below the extension line of the center line connecting the centers O ₆ , O ₇ ... Of B ₆ , B ₇ ...

Therefore, the pressure transmitted from the waiting balls B ₆ , B ₇ ... To B ₅ produces a component force that pushes down the ball B ₅ . by this,
When the downflow prevention member 22 is retracted, the flow control gutter 33 is the uppermost ball.
B ₅ is not sandwiched between the following ball B ₆ and the outer wall 33a of the diversion gutter 33, and does not prevent the balls B _{1 to} B ₄ from flowing down following the flow.

The discharge ball detector 25 provided in the middle of the guiding gutter 34,
The detection optical axis F is arranged so as to come to a position slightly deviated from the center of the sphere flowing down in the trough. When the detection optical axis F is positioned so as to pass through the center of the sphere, when a plurality of spheres continuously flow down, the pulse interval of the detection signal becomes narrow and accurate counting may not be possible. . However, in this embodiment, accurate counting can be performed by shifting the detection optical axis F from the center of the sphere as described above.

Further, the flow-down preventing member 22 is attached so that the rotation surface of the fan-shaped flow-down preventing member 22 coincides with the flow-down trajectory at the center of the flowing sphere, so that the flow-down prevention member 22 enters the gutter from above the guide gutter 34 downward. To stop the falling ball. Therefore, the impact force acting on the flow-down preventing member 22 when the flowing-down ball stops is received by the stopper portion (for example, the slit end of the guide gutter 34 into which the flow-down prevention member 22 enters). Therefore, it is possible to easily provide a strength capable of withstanding an impact acting at the time of stopping.

Moreover, since the ball B ₁ the lowermost is stopped in contact with the outer peripheral surface of the fan-shaped flow-down preventing member 22, while ball B ₁ the lowermost of the outer peripheral surface and the wall surface of the induction gutter 34 falling blocking member 22 It is stopped by the bite such forms also, when the falling preventing member 22 is retracted moves away while allowing to rotate the ball B ₁ at its outer peripheral surface. Therefore, the downflow prevention member 22 can be retracted with a comparatively small force, and the sphere is not caught between the downflow prevention member 22 and the wall surface of the guide gutter 34 and does not become stuck.

Further, the line connecting the rotation center of the flow-down prevention member 22 and the center O ₁ of the lowermost sphere B ₁ in the guide trough 34 is arranged so as to be horizontal. Therefore, immediately ball B ₁ is enabled under a stream when the end of the falling-blocking member 22 is disengaged from the outer periphery of the ball B _1, blocking force from ball B ₁ is lowered slightly shear with the rotation of the flow-down preventing member 22 is outside And there is no such thing as starting the flow.

Further, in the above-mentioned embodiment, the angle α formed between the diversion gutter 33 and the guiding gutter 34 may be in the range of 0 to 90 °, but if it is set to about 45 °, the acceleration is accelerated in the diversion gutter 33. Further, the speed of the falling ball is not significantly reduced, and the load applied to the falling prevention member 22 when stopped can be reduced.

Further, in the above-described embodiment, in a state in which the sphere is prevented from flowing down by the downflow prevention member 22, the distance from the contact point between the downflow prevention member 22 and the lowermost sphere B ₁ in the guide trough 34 is separated by the diameter of the sphere. The distance d between the vertical line G passing through the defined point and the wall surface 35a of the discharge gutter 35 is smaller than the radius r of the sphere and larger than r-rcosα (r-rcosα <d <r). The position of the end 34a of 34 has been determined. Thereby, when the flow-down preventing member 22 enters the guide gutter 34 and prevents the ball from flowing down, when the ball discharged at the end is discharged by being pushed by the end face 22a of the flow-down preventing member 22 When it reaches the end 34a of the guide gutter 34, it flows down into the discharge gutter 35 and the downflow prevention member 22
You can escape from. For this reason, the final discharge ball remains in the guide gutter forever and does not hinder the entry of the flow-down preventing member 22, and the discharge can be stopped quickly.

 FIG. 7 shows details of an embodiment of the winning ball processing apparatus 40.

An assembly shelf 10 provided on the back surface of the back mechanism panel 1 is inclined downward toward the center, and a flow path conversion unit 10C is provided at the center. This flow path conversion unit 10C is for changing the direction of the vertical wall 10a that causes a step between the left and right collecting shelves 10A and 10B and the winning balls that are fixed to the vertical wall 10a and have flowed down from the right collecting shelf 10A. A guide piece whose front end is formed in an arc shape.
10b, a tapered portion 10c formed so as to be gently downwardly inclined forward at the terminal end of the collecting shelf 10A below the guiding piece 10b.
It is composed of

Corresponding to the flow path conversion section 10C, an outlet 41a through which one sphere can pass is formed in a holding frame 41 integrated with a panel attached so as to cover the collecting shelf 10, and one side of this outlet 41a and An L-shaped winning ball guide plate 42 is provided along the lower side,
The inflowing winning balls are turned 90 degrees.

The ball processing device is located on the side of the winning ball guide plate 42
43 is pivotally mounted by a support shaft 44. On the side of the ball processor 43 facing the prize ball guide plate 42,
A concave ball receiving portion 43a is formed, and a weight 45 is attached to the opposite side thereof.
The mounting side of is lowered by its weight. The lower side of the ball receiving portion 43a on the opposite side is the winning ball guide plate 42.
And further rotation is prevented by contacting the lower surface of the, and the balance is maintained. In this state, when a winning ball flows down from the winning ball guide plate 42 to the ball receiving portion 43a as shown in FIG. 8 (A),
The weight of the weight 45 is determined so that the ball processor 43 rotates clockwise by the weight of the ball. The sphere processing device 43 rotated by the weight of the inflowing sphere is stopped when its lower side comes into contact with the holding frame 41.

In this stopped state, the prize ball guide plate 42
A blocking piece 43b is protrudingly provided at a position opposing to the above. As a result, if two or more winning balls are generated consecutively, 2
As shown in FIG. 8 (B), the second and subsequent winning balls are blocked from flowing down by the blocking piece 43b, and are made to stand by on the winning ball guide plate 42. Although the mounting position is not limited, for example, a detection piece 43c is provided on the upper part of the sphere processing device 43, and a pair of a projector and a light receiver are provided in the holding frame 41 corresponding to the detection piece 43c. A safe sensor 91 such as an optical sensor arranged opposite to each other is attached.

Further, a solenoid 46 is arranged on the side of the ball processing device 43, and a position facing the lower side of the ball receiving part of the ball processing device 43 rotated by the winning ball flowing into the ball receiving part 43a. The stopper 47 fixed to the tip of the plunger 46a of the solenoid 46 is exposed. This solenoid 46 is a stopper at the plunger tip in the demagnetized state.
47 is pulled downward by the spring 48, is held by the ball receiving portion 43a, and comes into contact with the winning ball that is about to flow down toward the winning ball outflow gutter 12 below to prevent the falling (the first (See FIG. 8B). When the solenoid 46 is excited, the plunger 46a contracts, the stopper 47 is raised, and the winning ball held in the ball receiving portion 43a flows down to the outlet gutter 12. The stopper 47
Is provided with an operation piece 47a, so that a staff member of a pachinko parlor can manually move the stopper 47 to discharge a winning ball when a ball is clogged or a solenoid fails.

The solenoid 46 is operated, for example, in response to a discharge completion signal from the prize ball discharging device 20. solenoid
When 46 is excited and the winning ball flows down, the ball processor 43
Is rotated counterclockwise by the weight of the weight 45, and the blocking piece 43b is raised. Therefore, the next winning balls that are continuously generated and kept waiting on the winning ball guide plate 42 are the ball receiving portions 43.
Then, the ball processing device 43 flows in a, and the ball processing device 43 is again rotated clockwise. In this way, by repeating the above-described operation, a large number of winning balls generated in a short time can be promptly separated and detected and processed.

As described above, as the prize ball discharging device 20, if a stopper type device that controls the discharge of the prize ball by using the solenoid to move the flow-down preventing member 22 into or from the flow-down path 30 to control the discharge of the prize ball, By installing a safe sensor in the middle of the lead-out gutter to detect a winning ball and electrically storing it, it is possible to perform high-speed discharge control.

On the other hand, in the winning ball processing device 40 of the above-described embodiment, since the winning ball is separated and detected one by one by the ball processor 43, a detection interval between the previous winning ball and the next winning ball is required, and We can take enough. Therefore, it is possible to more accurately detect the winning balls successively generated. In a conventional gaming machine using a ball-sheath case-type prize ball discharge device, the prize ball is controlled to be discharged by separating the prize balls one by one, but in the conventional prize ball processing device, the separation is performed. Move the lever with the winning ball, remove the stopper of the ball sheath case with that movement, tilt it and discharge it, furthermore, physically transmit the tilt of this ball sheath case to the ball processor and allow the next winning ball to flow down Therefore, the response speed is lower than that of the winning ball processing apparatus of the above embodiment, and it is not suitable for processing a large amount of winning balls in a short time.

Further, in the winning ball processing device 40 of the above embodiment, after confirming the end of the discharge in the prize ball discharging device 20, the solenoid 46
Is activated to eject the previous winning ball and control to proceed to the detection of the next winning ball, so that a prize ball is not paid out even if a winning ball is generated, such that a communication between the player and the game store can be performed. It is possible to prevent troubles occurring between them. In other words, if the prize balls are not discharged, the prize balls are left at the stopper, and it is immediately apparent whether the player's claim is correct or not by looking there. Moreover, because the winning balls and the prize balls are discharged in a one-to-one relationship, the processing of the winning balls is interrupted while the discharging is stopped, and the winning balls that have not been discharged are put on standby. Is unnecessary. In other words, if the winning balls are detected in advance and electrically stored in a memory or counter, it is necessary to take measures against power failure such as backup by a battery in order to prevent the number of stored data from being lost at the time of power failure, The use of the winning ball processing apparatus of the above embodiment eliminates the necessity.

Then, in the winning ball processing device 40 having the solenoid 46 as described above, the storage tank 1 when the game is stopped
Solenoid 46
Since the driving of is also interrupted, winning balls that have already been won remain on the collecting shelves 10A, 10B. Therefore, when a reserve ball is replenished to the storage tank 1 to open the game machine that has been stopped in that state for the next player, the winning ball left by the previous player at that time The prize balls will be paid out to the next player, which will give an unjustified profit to the next player.

Therefore, in the above-described embodiment, the memory discharge switch 83 that can be manually operated is provided on the upper portion of the back mechanism plate 1,
When this memory discharge switch 83 is operated once, the solenoid
46 is excited once, the stopper 47 is raised and the waiting winning ball is discharged, and the next winning ball is separated.
At this time, however, the detection signal of the safe sensor 91 detected by the swing of the sphere processor 43 is ignored. That is, when the memory discharge switch 83 is operated, only the winning balls are discharged, and the prize ball discharging device 20 does not discharge the prize balls.

Therefore, if the game is finished by stopping, the staff of the pachinko parlor operates the memory discharge switch 83 to operate the winning ball processing device 40, and the collecting rack 10A without discharging the prize ball, All winning balls remaining on 10B can be discharged.

FIG. 14 shows an example of the timing of control signals inside the gaming machine when the memory discharge switch 83 is operated. That is, when the memory discharge switch 83 is turned on, the prize ball lamp 111 is turned on and the safe solenoid 46 is set to 100.
Drive for m seconds. Then, one winning ball is discharged and the number of remaining winning balls is reduced by one. By repeating this, when the number of remaining winning balls becomes “0”, the winning balls do not flow into the ball processing unit 43. Therefore, the detection signal from the winning ball detector 91 is also a control device.
It will not come in 200. Therefore, the control device 200 does not turn on the prize ball lamp 111 or drive the safe solenoid 46 by operating the memory discharge switch 83 thereafter. Even if the memory discharge switch 83 is operated, the prize ball lamp 111 is no longer lit, so that the clerk can know that there are no remaining prize balls.

As described above, in this embodiment, even if there is no discharge end signal from the prize ball discharge device 20, the signal from the memory discharge switch 83 is driven as the pseudo discharge end to drive the solenoid 46 in the prize winning ball processing device 40, Since the winning balls can be discharged, the winning ball processing device 40 can be operated even when the storage tank 1 is emptied at the time of stopping and the prize ball discharging device 20 cannot perform the discharging operation.

Moreover, since the stopper 47 is provided with the operation piece 47a, in the case of a ball clogging in the winning ball processing device or a malfunction of the solenoid 46, a staff member manually operates the operation piece 47a to manually operate the stopper 4a.
You can move the 7 to eject winning balls.

Further, in the above embodiment, since the winning ball is detected by the indirect method of detecting the rotation of the ball processor 43, malfunction of the safe sensor 91 due to static electricity charged on the pachinko ball is prevented. . In other words, in the case of the above embodiment, it is possible to directly detect the winning ball by putting the sensor 91 in the path of the winning ball, but in such a case, the sensor malfunctions due to static electricity charged on the winning ball. However, erroneous operation of the sensor can be prevented by indirect detection.

In the above embodiment, the winning ball processing apparatus is configured as shown in FIG. 7, and accordingly, the right collecting rack 10A is provided with an inclination angle α of 6 to 8 ° and the left collecting rack 10B is provided. Is an inclination angle β of 14 to 16 °, and the left and right shelves 10
Differentiate the speed of the winning ball flowing down A and 10B,
The height h of the vertical wall 10a is set to 12 mm or more. Thereby, even if a plurality of winning balls are generated and the winning balls flow down simultaneously from the left and right, it is possible to prevent the clogging of the balls in the flow path conversion unit 10C beforehand.

Next, a control device 200 that controls the prize ball discharging device 20 to discharge a predetermined number of prize balls and control the hit ball launching device 103 and the like.
An embodiment will be described with reference to FIG.

In this embodiment, control of the prize ball discharging device 20 and the like is performed by the CPU.
(Microcomputer) 200 '.

The CPU 200 'includes a prize ball number setting device 81,8 in the above embodiment.
2, a memory ejection switch 83, a ball removal switch 84, a safe sensor 91, an overflow detector 92, and a ball shortage detector 93 are input. By providing the prize ball number setting devices 81 and 82, models (pachinko machines) having different numbers of prize balls can be controlled. Also,
A discharged ball detection signal from a pair of discharged ball detectors (hereinafter referred to as discharge sensors) 25 provided in the middle of the flow-down path 30 of the prize ball discharging device 20 is input to the CPU 200 '. . Further, a stop command signal from a central management device of a pachinko parlor (not shown) is input to the CPU 200 '.

The CPU 200 'has a ROM 201, which is a read-only memory, and a RAM 202, which is a memory that can be read and written at any time. Among them, the ROM 201 stores fixed data such as a program to be executed by the CPU 200 'for controlling the prize ball discharging device 20 and the driving time of the safe solenoid 46 and a wait time (discharge interval). On the other hand, the RAM 202 sets a memory area for storing the cumulative number of balls discharged from each downflow path 30 or the number of discharged balls in each downflow path based on the discharged ball detection signal from the above discharge sensor 25, or software. It provides the register area that constitutes the timer and the CPU 200 'work area.

Further, the CPU 200 ′ has a pair of solenoids (hereinafter referred to as discharge solenoids) 21 in the prize ball discharging device 20 and a solenoid (hereinafter referred to as safe solenoid) 46 in the winning ball processing device 40 via the driver 220, and Award ball lamp
Display devices such as 111, completion lamp 112, overflow lamp 113, injustice warning display lamp 114, malfunction indicator lamp 115, prize ball number indicator 116, pilot lamp 117 (all see FIG. 2), speaker 120, ball hitting The device 103 and the like are connected. The CPU 200 'drives the prize ball discharging device 20, various display lamps, a ball hitting device 103, etc. based on signals from the setting device, various detectors and switches according to a program in the ROM 201.

The main processes of the CPU 200 'are an overflow process, a tank process, a ball removing process, a winning ball detecting process, and a prize ball discharging process. However, the procedure of the process is not limited to the above order, and any process may be performed first. The pachinko gaming machine is controlled by repeatedly executing the above processing by a timer interrupt or the like.

Here, the overflow processing detects the detection signal from the overflow detector 92, and turns on or blinks the overflow lamp 113 for a predetermined time (10 to 20 seconds), for example, when the overflow state is not released. Means that the launching operation by the hit ball launching device 103 is stopped. As a result, the prize ball outlet gutter 13
The inside is filled with prize balls up to near the prize ball discharge device 20,
It is possible to avoid adversely affecting the discharging operation.

When the tank processing detects that the storage tank 2 is empty and the ball shortage detector 93 is turned off, for example, a ball supply request is sent to the central control room and the completion lamp 112 is turned on, and at the same time or After that, when the ballless state is detected based on the signal of the discharge sensor 25 in the prize ball discharging device 20, the hitting ball launching device 103 is stopped. When a ball supply request signal is sent to the central control room, a supply device (not shown) above the tank is operated by a command from the central control quality,
Supply to the storage tank 2 is performed. In this example,
Even if the presence of balls in the tank is detected by the signal from the ball shortage detector 93, the discharge of the prize balls is not immediately restarted, and
As shown in the figure, for example, after the delay time td of 2 seconds elapses, it is restarted. The delay time was added to the guide gutter after the tank was refilled.
In consideration of the time difference until 11 is filled with the spare balls, the empty discharge in the prize ball discharging device 20 is prevented by this.

Based on the signal from the ball removal switch 84, the ball removal processing is switched to the direction in which the switching gate of the ball removal device 60 is opened in the direction of opening the entrance of the ball removal trough 16 and closing the entrance of the prize ball derivation trough 13. When detected, the solenoid 21 in the prize ball discharge device 20
Is operated to continuously discharge the reserve sphere through the two flow-down paths 30 to empty the storage tank 2.

The winning ball detecting process and the prize ball discharging process are interrelated and complicated, and therefore, timing charts are shown in FIGS. 17 to 20 and will be described below based on the timing charts.

When the process is started by turning on the power or the occurrence of an interrupt, the CPU 200 'first initializes a safe memory that stores the number of winning balls and various registers before detecting the winning balls, and then the prize ball discharging device 20. The number of discharged balls (hereinafter referred to as the number of discharged bases) is determined once for each of the downflow routes.

In the gaming machine of the above-described embodiment, prize ball number setting devices 81 and 82 formed of dip switches are provided for setting the number of discharged balls. Therefore, the CPU 200 'uses these switches 81,8
In accordance with the combination of the ON and OFF states of 2, the discharge bases 1 and 2 are determined as shown in the following table, for example, and the total number of prize balls is displayed on the display 116 on the front of the gaming machine. Here, as an example, a case where the total number of prize balls is set to 11, 13, or 15 is shown.

In Table 1 above, the term “discharge solenoid 1 side” refers to a solenoid provided on a path closer to the mounting board among the two flow-down paths, and in Table 1 above, the discharge solenoid 1
The number of discharge bases on the side is always determined to be larger than that on the discharge solenoid 2 side. The reason for setting such a relationship is that when the flow-down route is set to two lines, the storage tank 2
The flow of the spheres flowing down to the prize ball discharge device 20 through the guide gutter 11 is smoother on the flow path on the side closer to the substrate, and the sphere tends to be always short on the far side. This is because it became clear experimentally. Therefore, by always increasing the number of discharge bases on the side of the discharge solenoid 1 as shown in Table 1, it becomes possible to balance the supply of the balls to the two flow paths.

When discharging the set n prize balls by the prize ball discharge device 20 shown in FIG. 3, the balls blocked by the flow-down preventing member 22 are located downstream of the mounting position of the discharge sensor 25. There is one, and the next discharge command is waited while the discharge sensor 25 is detecting the previous ball. Therefore, in actual control, n that is "1" less than the set number n
It is necessary to change the control signal for the solenoid 21 which operates the downflow prevention member 22 when the discharge sensor detects the -1st ball.

During normal operation, as shown in the timing chart of FIG. 17, the winning memory of the safe memory becomes “1” in response to the rise of the output of the safe sensor, the safe lamp is turned on, and the discharge solenoids 1 and 2 are turned on. Turned on. Then, the discharge of the prize balls is started, and the discharge sensor 1
The outputs of 2 and 2 change for each discharge ball, and when the predetermined number (base-1 in Table 1) is reached, the demagnetization command of the solenoid is issued, the corresponding discharge solenoid is turned off, and the safe lamp is turned off. . At the same time, the safe solenoid is turned on for only about 100 msec to discharge the winning ball, and the next winning ball can be accepted. On the other hand, the discharge wait timer is turned on at the same time as the safe solenoid is turned on, and the start of the discharge of the next prize ball is waited until the time is up (600 ms).

Since the set time of the safe solenoid timer is set to 100, the stopper 47 driven by the safe solenoid 46 is raised for 100 ms, and this stopper 4
The winning balls that have been blocked by 7 can be reliably discharged, and the winning ball that has flowed into the winning ball processing device 40 next can be swiftly moved to a standby state.

Also, because the discharge wait timer is set to 600 ms, the ball in the guide gutter 11 can stabilize before the discharge and the next discharge can be performed, ensuring the accuracy of discharge. .

In this embodiment, however, if a ball clogging occurs in the flow path 30 of the guide gutter 11 or the prize ball discharging device 20, and if no ball state is detected during the prize ball discharging operation, the corresponding path side The discharge solenoid 21 is turned off to display a malfunction indication.

That is, for example, as shown in FIG.
If the ball clogging occurs when 3 discharge balls are detected and the output of the sensor 1 remains low level, the CPU turns off the discharge solenoid 1 after 10 seconds. At the same time, the prize ball lamp 111 is turned off, and the malfunction indicator lamp 115 is made to blink at a cycle of 400 msec, for example. Moreover, in the above case,
Even if the discharge solenoid is turned off, the winning memory in the safe memory is retained as it is without being subtracted, and the operation of the safe solenoid is suspended. In other words, the winning solenoid is originally turned off, the winning memory is subtracted, and then the safe solenoid is turned on.
The next prize ball is taken into 40 and detected, and the prize ball discharging device 20 is activated again, but in this embodiment, when a ball clogging occurs in the prize ball discharging device 20, the prize ball in the prize ball processing device 40. Separation and detection are interrupted and a malfunction is displayed.

Therefore, an attendant of the game shop can see the malfunction display lamp 115 and know that the malfunction has occurred, and can promptly deal with it.

Then, when the ball clogging is cleared by the staff and the output signal of the discharge sensor 1 changes to a high level as shown in FIG. 18, the discharge solenoids 1 and 2 of the prize ball discharge device 20 are turned on again after 2 seconds have elapsed. At the same time, the malfunction display is stopped and the prize lamp 111 is turned on.

On the other hand, the prize ball discharging device 20 cannot perform accurate discharging even when the discharging sensors 1 and 2 and the discharging solenoid are broken. In this embodiment, as shown in FIG.
If the output of the discharge sensor 1 (or 2) remains high level after detecting the predetermined number of prize balls (6 pieces) after turning on 1 and 2, this state is 1.5 When continuing for a second, the drive signal of the discharge solenoid 1 (or 2) is dropped to a low level, the safe lamp is turned off, and the malfunction indicator lamp 115 is made to blink at a cycle of, for example, 200 msec. Therefore, the attendant of the game shop can see the display and know that the malfunction has occurred, and can take an appropriate action such as the replacement of the solenoid or the sensor.

Even if the discharge solenoid or the discharge sensor has failed before the start of discharge, the output of the discharge sensor does not change and remains at the high level, so that a malfunction indication is displayed after 1.5 seconds.

Moreover, as described above, the blinking cycle of the malfunction indicator lamp is changed between when the ball is clogged and when the discharge solenoid or discharge sensor fails (400 msec and 200 msec), so the staff must guess the cause of the defect. It is possible to respond more quickly. Further, when a malfunction is detected, the winning memory of the safe memory is held without being subtracted, so that the player is not disadvantaged that the prize ball has not been paid.

Further, since the discharge solenoid is turned off when the malfunction is detected, it is possible to prevent the solenoid from being excited for a long time and generating heat.

Further, in this embodiment, if the safe solenoid 46 in the winning ball processing device 40 fails and the separation and detection of the winning balls do not proceed, this is automatically detected and a malfunction display is performed. It is like this. That is, when the safe solenoid 46 fails during the discharge of the prize ball as shown by the symbol K in FIG. 20, if it is normal, the prize ball discharge end signal is received and the stopper 47 is removed to discharge the prize ball. Where the output signal of the safe sensor 91 should rise to the low level as shown by the broken line B in the figure, it remains in the high level state.

Therefore, in this embodiment, the CPU 200 'determines that the output of the safe sensor 91 remains at the high level even after a suitable time T has elapsed from the end of the discharge (when the discharge solenoid 21 and the safe lamp 111 are turned off). , Malfunction indicator lamp
It is designed to turn on 115. Therefore, an attendant of the game shop can know that a failure has occurred by looking at the malfunction display lamp. Then, the clerk lifts the operation piece 47a provided on the stopper 47 and hooks it on a locking portion (not shown) provided on the holding frame 41. Then
After that, the winning prize processing device 40 operates with the stopper 47 removed. That is, regardless of the presence or absence of the discharge end signal from the prize ball discharging device 20, the ball processor 43 rotates when the winning ball comes in, the safe sensor 91 detects this, and the winning ball remains winning. It flows down into the sphere lead-out gutter 12 and the sphere processor 43
Rotates to the opposite side under the weight of the weight 45 and receives the next prize ball. By repeating this, the generated winning ball is detected regardless of the discharging operation in the prize ball discharging device 20. Moreover, the CPU 200 'counts the detection signals of the safe sensor 91 and holds the number of winning balls in the internal storage area (safe memory).

When the stopper 47 is forcibly removed by the staff, the output signal of the safe sensor 91 changes to the low level when the winning ball is discharged and the ball processor 43 returns to the original level.
Know that the malfunction condition of U200 'has been released. Therefore, the malfunction indicator lamp 111 is turned off. After that, CPU200 ′
The prize ball discharge device according to the winning memory in the safe memory
Instead of sending the discharge command signal to 20, and driving the safe solenoid 46 in response to the discharge end signal, the winning memory of the internal safe memory is decremented by one.

As described above, in this embodiment, by simply removing the stopper 47, the number of winning balls is electrically stored thereafter, and the discharge of the prize balls is controlled based on this, so the safe solenoid 46 fails. Even so, the game can be continued.

In the above embodiment, when the prize ball discharging device 20 has an abnormality, the malfunction display lamp 115 is made to blink. However, instead of the lamp, a speaker or a buzzer is used to notify the malfunction by voice. You may do it.

Further, in the pachinko gaming machine of the above embodiment, a special device is added to the drive circuit of the discharge solenoid 21 in the prize ball discharge device 20. That is, as shown in FIG. 21, various display lamps L, the discharge solenoid 21, and the safe solenoid 46 connected between the power supply voltage terminal VA and the ground point.
Is the switch transistor connected in series with them
It is designed to be driven by turning on / off Tr ₁ , Tr ₂ , Tr _3, etc., but in the above embodiment, in parallel with the discharge solenoid 21, higher than the peak value of the power supply voltage, for example,
Zener diode D with Zener voltage like 24V
z is connected.

Therefore, when a voltage of full-wave rectified AC 24V AC is applied to the power supply voltage terminal VA, when the transistor Tr ₂ is turned off, normally the solenoid is completely demagnetized as shown in FIG. 22 (A). Although it took t ₁ hour, if the Zener diode Dz is connected in parallel with the solenoid coil, this acts as a means for forcibly releasing energy, and the demagnetization time of the solenoid is shortened. That is, the 22nd
The time t _{2 at} which the areas S ₁ and S ₂ of the shaded portions in FIGS. 10A and 10B become equal to each other is the demagnetization time when the Zener diode Dz is inserted. As a result, the Zener voltage is 24V
In the case of, the degaussing time is about half that in the case without the Zener diode, and the prize ball ejector 20
The response speed of the flow-down prevention member 22 at is fast.

In FIG. 21, the diode D ₁ connected in reverse direction in series with the Zener diode Dz is for holding the transistor Tr ₂ from the back electromotive force of the solenoid, and is also used for the switch transistor Tr ₃ of the safe solenoid 46. A similar protection diode D ₂ is provided. However, since the safe solenoid 46 does not require a response that is so fast as the discharge solenoid 21, the Zener diode Dz is unnecessary.

In the embodiment, the prize ball discharging device is operated based on the prize ball detection signal in the prize ball processing device to discharge a predetermined number of prize balls, and the prize ball discharging end signal is used to output the prize ball. The drive source in the processing device is operated to remove the stopper, and the winning ball in the ball receiving portion is allowed to flow down so that the next winning ball can be received, but in the present invention, the winning ball processing device 40 is not always required. It is not necessary to provide the stopper 47 and its drive source (solenoid) 46 therein. In other words, the sphere processor 43 of the above-mentioned embodiment does not perform electrical control, and the weight and weight of the winning sphere that has flown in itself is
Because it swings to the left and right alternately depending on the balance with 45, it is possible to automatically separate the winning balls and let them flow down. Then, the winning balls thus separated are detected one after another, stored in the memory or the counter in the control device 200, and the prize ball discharging device 20 is operated only the number of times corresponding to the number of winning memories. It is possible to do so.

[Effects] As described above, according to the present invention, the game board having at least the variable prize device in the game section is detachably attached to the game machine body, and the variable prize is provided on the back mechanism board on the back side of the game machine. A ball ejection device provided with a ball ejection device capable of ejecting a predetermined number of balls based on a hit ball that has won a winning portion including a device, and a control device electrically controlling the variable winning device and the ball ejection device. In the gaming machine, the control device is a first control device (game content control device 210) that electrically controls game control including the variable winning device, and a second control that electrically controls discharge control of the ball discharging device.
