Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a stopper (flow-down preventing member) in a flow-down path.
The present invention relates to a technology effective for use in a pachinko game machine having a stopper-type prize ball discharging device that discharges a prize ball by causing the prize ball to be discharged by moving in or out.

[Prior Art] A prize ball discharge device in a conventional pachinko game machine generally uses a swingable ball-sheath case, and the ball-sheath case separates winning balls one by one and separates them. The lever was rotated by the weight of the ball, and was physically transmitted to move the lever.

However, many recent pachinko machines have a large variable prize winning device that creates a state in which a large number of prize balls can be obtained, so-called lucky sevens.

In a pachinko game machine having such a large variable winning device, there are many occasions in which a simultaneous or continuous winning ball is generated. However, in the conventional prize ball discharge device of a ball-and-sheath case type operated by transmission of a physical force generated by a winning ball, there is a limit to speeding up due to friction of each mechanism.

Therefore, at the bottom opening of the storage tank disposed on the upper back of the game board, a guide gutter having one end is arranged so as to be gently inclined downward toward the other end, and at the end of the guide gutter, A gutter constituting a downflow path, a downflow prevention member capable of entering the downflow path, and a drive source of the downflow prevention member, and a predetermined number of the downflow prevention members are made to enter or retreat into the downflow path. There has been proposed a prize ball discharge device configured to discharge a ball (hereinafter, referred to as a stopper-type prize ball discharge device).

[Problems to be Solved by the Invention] However, in a conventional pachinko game machine using the stopper type prize ball discharging device of the above-mentioned electrically controllable type, the driving source of the downflow prevention member is simply provided. There is no means for confirming whether or not the prize ball discharging device is operating in an appropriate state only by controlling the operation and the stop.

Therefore, even if the player inserts a piano wire or the like into the pachinko ball machine to forcibly open the downflow prevention member and illegally discharge the prize ball, it cannot detect this, and unreasonable profits There was a problem that it could be obtained.

[Object of the Invention] An object of the present invention is to prevent a player from misappropriating a prize ball discharge device, thereby improving the soundness of a pachinko game, and eliminating the risk of unexpectedly damaging a pachinko game store. An object of the present invention is to provide a pachinko gaming machine capable of stabilizing.

[Means for Solving the Problem] In order to solve the above problems, the present invention provides a game board having a plurality of prize areas and a game board which allows or blocks a flowing game ball from passing therethrough.

A discharge ball detector capable of detecting the flow of the discharged game balls one by one, supplying a detection signal from the discharge ball detector to the control means, and the control means including the discharge ball detection Discharge based on the detection signal from the A discharge ending means for counting the number of technical balls and terminating the discharge when the number of discharged balls reaches a predetermined number, and a game in spite of the fact that the operating member is not in an operating state based on a signal from the discharged ball detector. An improper operation state detecting means for detecting an improper operation state of the ball discharge device, in which a ball is discharged and a detection signal is detected from the discharge ball detector, is provided.

[Operation] According to the above-mentioned means, the playing ball blocking state of the operating member is illegally released by the insertion of a piano wire or the like from the outside, or the operating member is not in the operating state due to breakage of the operating member or failure of the drive source. Nevertheless, when the game ball is ejected, it is immediately detected by the inappropriate operation state detecting means. Therefore, by using the detection output, the improper warning indicator lamp or the malfunction lamp is activated to prevent the improper act and prevent the malfunction. Early detection becomes possible.

Embodiment FIG. 1 shows a configuration example of a back mechanism of a pachinko game machine according to the present invention.

A reserve sphere storage tank 2 is disposed above the back mechanism panel 1, and a guide gutter 11 is connected to one end of the storage tank 2 for automatically aligning and guiding the internal reserve sphere. The guide gutter 11 has two passages, is gently inclined, and is provided with a pendulum type ball nose 3 and a press type ball nose 4 on its way. While flowing down, they are aligned in two rows.

A stopper-type prize ball discharging device 20 (see FIG. 4) as a ball discharging device is provided at the lower end of the guide gutter 11.
It is arranged. A hit ball that has won a prize hole provided in a game board on the front of the pachinko gaming machine 100 (see FIG. 2) is collected on the back surface, collected at one place by the collecting shelf 10, and one by a prize ball processing device 40. Each is separated and detected by the winning ball detector 91, and as a result, a discharge command signal is formed. Then, the prize ball discharge device 20 is operated only once, and a predetermined number (for example, 13) of prize balls are discharged. The prize balls separated and detected by the prize ball processing device 40 are discharged to a collecting gutter (not shown) at the rear of the gaming machine through the outlet trough 12, and when the prize ball discharge device 20 finishes discharging the prize balls, the discharge ends. Upon receiving the signal, the winning ball processing device 40 separates and discharges the next winning ball.

On the other hand, the prize balls discharged by the prize ball discharge device 20 flow out of the supply port 14 to the supply plate 101 (see FIG. 2) on the front of the gaming machine through the prize ball lead-out gutter 13. When the supply tray 101 is full, the prize ball is discharged to the tray 102 under the entire surface of the gaming machine through the diversion gutter 15. When the saucer 102 is full,
This is detected by an overflow detector 92 provided in the middle of the diversion gutter 15, and for example, the driving of the hit ball launching device 103 is stopped.

When the overflow detector 92 detects an overflow state of the tray, an overflow indicator 113 is provided on the front of the game device to notify the player of the overflow state.

On the front of the gaming machine 100, the overflow indicator 113
In addition, the prize ball lamp 111 is turned on each time a prize ball is discharged in accordance with the occurrence of a prize ball, and the number of discharged prize balls reaches a predetermined number when the storage tank 2 becomes empty or when the storage tank 2 is discharged. A completion lamp 112 which is lit when reaching, a fraud warning display lamp 114 which is lit or blinked when there is a fraudulent act of intentionally activating the prize ball discharging device 20 by inserting a piano wire or the like, a prize ball discharging device Malfunction indicator lamp 115 that is turned on or blinks when a ball is clogged, a discharge solenoid, a discharge sensor, etc. breaks down, a prize ball indicator that displays the number of prize balls paid out in response to one winning ball
Various display devices such as a pilot lamp 117 that is lit while the firing motor of the hit ball firing device 103 is driven are provided. The prize ball number display 116 is, for example, 3
It consists of a transparent plate on which the number of award balls is described, and three lamps respectively arranged behind the transparent plate. Lamps corresponding to the number of award balls set by a setting device (described later) are selectively turned on. Is displayed.

105 is an out hole for collecting the hit ball which did not win in the winning opening out of the hitting holes into the winning board out of the hitting hole on the back of the game board, and 93 is when there is no spare ball in the storage tank 2.
This is a ball shortage detector for detecting this.

A ball drain gutter 16 is provided below the prize ball discharge device 20 in parallel with the prize ball discharge gutter 13, and is switched to an entrance of the ball drain gutter 16, that is, a branch point with the prize ball discharge gutter 13. A ball removing device 60 having a gate is provided. The ball punching device 60 includes an operation hole 1 formed on the front surface of the holding frame 104 of the gaming machine.
From 06, the gate can be activated by inserting a tool such as a pin or a wire. When the switching gate is switched to the ball drain gutter 16 side, the ball drain switch 84 is turned on.

In a pachinko gaming machine using a conventional ball-and-sheath case, a ball-extraction gate was provided on the upstream side of the prize-ball discharge device 20, so even if the ball was removed, the ball remained on the way. In this embodiment, the ball punching device 60 is the prize ball discharging device 20.
Because it is on the downstream side, all balls can be pulled out, and the data of pachinko parlors can be collected accurately.

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 includes a control device for performing electrical control of the entire pachinko gaming machine, such as stopping the launch of a hit ball by a detection signal from the prize ball discharge device 20 or the overflow detector 92, and driving various display devices. A game content control device 210 is provided for controlling the game operation based on signals from detectors incorporated in 200 and various variable prize 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 invariable part together with the game board before the end of its life.

In the above embodiment, when exchanging the game board, only the game board and its game content control device 210 need be exchanged. That is, the game content control device 210 is fixed to the back of the removable game board,
The winning ball processing device 40 and its control device 200 are fixed to the back mechanism board 1 integrated with the main body of the gaming machine together with the spare ball storage tank 2 and various guide gutters 10 to 17. Therefore, even when the game board is replaced, most of the main body and the back mechanism board can be left as they are and can be used continuously, which is very economical.

On the outer surface of the control device 200, prize ball number setting devices 81 and 82 including dip switches and the like are attached in order to set the number of discharged 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. This is detected by the ball unexpected detector 93 to form a ball supply 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 fly 3 is hung 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 flats 4 are rotatably supported by pins 4b on support pieces 4a fixed to both ends of the guide gutter 11, and prevent the balls flowing down on the guide gutter 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 tip bent piece of the flow-down control member 7 is divided into two parts, and when turned as shown by the broken line a in the figure, each bent piece 7c, 7d corresponds to the two guiding paths and the guide gutter 11 By entering the long holes 11c and 11d formed in the upper wall of the, the flow of the ball in the guide gutter 11 is prevented, and the supply to the prize ball discharge device 20 can be manually interrupted.

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 the prize ball discharging device 20 in detail.
The prize ball discharge device 20 includes a flow-down path 30, a flow-down preventing member 22 that enters the flow-down path 30 and controls the flow of a ball, and a solenoid 21 that is a driving means thereof are integrally connected.

The flow-down path 30 includes an alignment gutter 31 that is gently inclined,
A flow control gutter 33 extending substantially vertically downward from the lower end of the alignment gutter 31; and an adjustment unit for changing the direction of the flowing ball at the connection between the alignment gutter 31 and the flow gutter 33 by about 90 degrees. 32, a guiding 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 guiding 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. The tip of the flow-down preventing member 22 enters through a slit provided on the inner wall of the flow-down path 30 and projects 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, a predetermined number of discharges are performed while allowing or preventing the flow of the ball.

Further, the side wall of the guide gutter 34 swells to the outside, and the storage portion 37
A discharge ball detector 25 composed of a transmission type optical sensor is inserted into the storage section 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, an engaging portion 13a formed at the start end of the prize ball lead-out gutter 13 is engaged with the lower end of the flow-down path 30 to perform connection.

Further, as shown in FIG. 5, a conductive sheet 38 such as a metal plate is attached to the bottom of the alignment gutter 31 at the entrance of the flow-down path 30, and one end of the conductive sheet 38 is grounded to a frame or the like. I have. 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, a method using a mechanical type detector such as a microswitch as the detector is also conceivable,
Since the return operation of the microswitch is slow, if the ball continuously flows down, the microswitch may be kept on and remain chattering easily. In addition, contact failure tends to occur due to long-term use. Therefore, the microswitch is not suitable as a detector for continuously discharging balls as in 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 in 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. In the slits 31a and 33a, a lid member 3 having a step portion 39a having substantially the same size as the slit is provided.
9 is engaged, fixed to a screw or the like, and 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 aligned in the flow-down path 30 are stopped when the foremost ball B ₁ comes into contact with the outer peripheral surface of the flow-down preventing member 22. At this time, two balls B ₁ and B ₂ are placed in the guiding gutter 34,
The dimensions of the guiding gutter 34 and the regulating gutter 33 are determined so that _three balls B ₃ , B ₄ , B ₅ are accommodated in the regulating gutter 33. Moreover, the uppermost ball B ₅ in the flow control gutter 33 is aligned with the alignment gutter 31.
Are pressed by the inner spheres B ₆ , B _7, ... And come into contact with the tapered adjusting portion 32. The ball B ₅ receives the repulsive force from the adjusting unit 32 by being pressed toward the adjusting unit 32,
Its repulsive force is transmitted to the ball B _4, B ₃ ...... spheres B ₅ and its lower, acts them to push downward. As a result, when the flow-down preventing member 22 is retracted from the guiding 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-controlling gutter 33 and the guiding gutter 34 to have the same flow. The spheres B _{1 to} B ₅ immediately start flowing down.

When the balls B _{1 to} B ₅ flow down, the balls B ₆ , B _7, ... In the alignment gutter 31 start flowing down subsequently. Then, at the outlet of the alignment gutter 31, it first collides with the adjustment unit 32 to reduce the flow speed, and the flow direction is changed from the horizontal direction to the vertical direction by approximately 90 °, and enters the flow adjusting unit 33. 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, the flow can be prevented before the ball B ₇ passes. By increasing the ball interval in this way, control of the flow-down preventing member becomes easy. However, to detect B ₇ prize balls to be discharged when the solenoid is switched to the OFF 21 is six.

Furthermore, the falling path 30, the center O ₅ of the sphere B ₅ located uppermost falling preventing member 22 by ball falling is prevented has been that control flow trough while 32 aligned in the alignment trough 31 The dimensions of the guiding gutter 34 and the flow control gutter 33 are determined so as to be located below the extension of the center line connecting the spheres B ₆ , B ₇ ... Center O ₆ , O ₇ .

Therefore, the pressure transmitted from the waiting balls B ₆ , B _7, ... To B ₅ generates a component force that pushes down the ball B ₅ . As a result, when the downflow preventing member 22 is retracted, the ball B ₁ is sandwiched between the uppermost ball B ₅ of the flow control gutter 33, the subsequent ball B _6, and the outer wall 33 a of the flow control gutter 33, and the ball B _1. It never is prevented from trying to flow down to follow the stream of ~B _4.

The discharge ball detector 25 provided in the middle of the guiding gutter 34,
The detection optical axis F is arranged at a position slightly deviated from the center of the sphere flowing down the gutter. When the detection optical axis F is positioned so as to pass through the center of the sphere, if a plurality of spheres flow continuously, the pulse interval of the detection signal may be narrowed and accurate counting may not be performed. . 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, with a relatively small force
22 can be retracted, the downflow prevention member 22 and the guide gutter 34
The ball does not get stuck between the wall and the wall.

Further, a line connecting the rotation center of the flow-down preventing member 22 and the center O ₁ of the lowermost ball B ₁ in the guide gutter 34 is disposed horizontally. Therefore, the end of the downflow prevention member 22 is
_As soon as it deviates from the outer circumference of ₁ , the ball B ₁ can flow down,
Blocking force from ball B ₁ is lowered slightly shear with the rotation of the flow-down preventing member 22 is removed, there is no such thing as to start the flow.

Further, in the above embodiment, the angle α between the flow control gutter 33 and the guide gutter 34 may be in the range of 0 to 90 °, but if the angle α is set to around 45 °, acceleration is performed in the flow control gutter 33. The speed of the falling ball is not greatly reduced, and the load on the falling prevention member 22 when the ball is stopped can be reduced.

Furthermore, in the embodiment, in a state in which a stream of balls is prevented by the falling-preventing member 22, one diameter of the sphere from a connection point between the ball B ₁ of the lowermost end of the induction gutter 34 and flows down blocking member 22 away The guiding gutter 34 such that the distance d between the vertical line G passing through the set 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). Of the terminal 34a is 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
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 one embodiment of the winning ball processing device 40.

The collecting shelf 10 provided on the back surface of the back mechanism board 1 tends to descend 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 creates a step between the left and right collecting shelves 10A and 10B, and the winning ball fixed to this vertical wall 10a and flowing down from the right collecting shelf 10A. Guidance 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 converter 10C, an inlet 41a through which one ball 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 the inlet 41a and An L-shaped winning ball guide plate 42 is provided along the lower side,
The incoming prize ball is 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 ball processing device 43 rotated by the weight of the flowing ball is stopped when the lower side abuts on 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, when two or more winning balls are generated successively,
As shown in FIG. 8 (B), the winning prize balls subsequent to the third prize ball are prevented from flowing down by the blocking pieces 43b and are made to stand by on the prize ball guide plate. Further, although the mounting position is not limited, for example, a detection piece 43c is provided on the upper part of the ball processing device 43, and a pair of a light emitter and a light receiver are provided on the holding frame 41 corresponding to the detection piece 43c. A safe sensor 91 such as an optical sensor disposed opposite to the light sensor is attached.

Further, a solenoid 46 is disposed on the side of the ball processing device 43, and is located at a position opposed to the lower side of the ball receiving portion of the ball processing device 43 which is rotated by the inflow of the winning ball into the ball receiving portion 43a. Further, a stopper 47 fixed to the tip of the plunger 46a of the solenoid 46 faces. This solenoid 46 is a stopper at the plunger tip in the demagnetized state.
47 is pulled down by the spring 48, and is brought into contact with a prize ball held by the ball receiving portion 43a and flowing down to the lower prize ball outlet gutter 12, thereby preventing the prize ball from flowing down. (See FIG. 8 (B)). When the solenoid 46 is excited, the plunger 46a contracts and the stopper 47 is raised, so that the winning ball held in the ball receiving portion 43a flows down toward 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 ball which has been continuously generated and kept waiting on the winning ball guide plate 42 is the ball receiving portion 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 operation, a large amount of winning balls generated in a short time are 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, winning balls continuously generated can be detected more accurately. 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 discharging in the winning 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 there is no ejection of the prize ball, the winning ball remains at the stopper, so that it can be seen immediately whether or not the player's claim is correct. In addition, there is a one-to-one relationship between the winning balls and the prize balls, and while the discharging is stopped, the processing of the winning balls is interrupted, and the undischarged winning balls are kept on standby. Becomes 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.

Further, in the above embodiment, the winning ball is detected by an indirect method of detecting the rotation of the ball processing or the like 43, so that the malfunction of the safe sensor 91 due to the charged static electricity of 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 device is configured as shown in FIG. 7, correspondingly, the right collecting shelf 10A is given an angle of 6 to 8 ° as the inclination angle α, and the left collecting shelf 10B is provided. Gives an angle of 14 to 16 ° as the inclination angle β, and sets the left and right
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.
One 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 as a read-only memory and a RAM 202 as a memory which can be read and written as needed. The ROM 201 stores a program to be executed by the CPU 200 ′ for controlling the prize ball discharge device 20 and the like and fixed data such as a drive time per one time of the safe solenoid 46 and a wait time (discharge interval). I do.

On the other hand, the RAM 202 sets a memory area for storing the cumulative number of balls ejected from the angular falling path 30 based on the ejected ball detection signal from the ejection sensor 25, the number of ejected balls in each of the descending paths, and software. A register area constituting a timer and an unauthorized counter for counting a detection signal from a discharge sensor when a discharge solenoid is turned off are provided.

Further, the CPU 200 'is provided with a pair of solenoids (hereinafter referred to as "discharge solenoids") 21 in the prize ball discharge device 20, a solenoid (hereinafter referred to as "safe solenoid") 46 in the prize ball processing device 40 via a driver 220, and further, , Award ball lamp
111, a completion lamp 112, an overflow lamp 113, a fraud warning display lamp 114, a malfunction display lamp 115, a prize ball number display 116, a display device such as a pilot lamp 117 (refer to FIG. 2), a speaker 120, and a hit ball firing The device 103 and the like are connected. The CPU 200 'drives the prize ball discharging device 20, various display lamps, the hit ball launching device 103, and the like based on signals from the setter, 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 processing is not limited to the above order, and the processing may be started from any processing. 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, it sends a ball supply request to the central control room and turns on the completion lamp 112, and After that, when the ball absence state is detected based on the signal of the discharge sensor 25 in the prize ball discharge device 20, the hit ball firing 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 state of the ball in the tank is detected by the signal from the ball shortage detector 93, the discharge of the prize balls is not immediately restarted.
As shown in the figure, the operation is restarted after waiting for elapse of a delay time td of, for example, 2 seconds. The delay time is set in consideration of the time difference between when the tank is replenished and when the guide gutter 11 is filled with the spare ball, thereby preventing the prize ball discharging device 20 from being discharged empty.

The ball-pulling processing is based on a signal from the ball-pulling switch 84 that the switching game of the ball-pulling device 60 has been switched to the direction of opening the entrance of the ball-pulling gutter 16 and closing the entrance of the prize ball derivation gutter 13. Upon detection, the solenoid 21 in the prize ball discharging 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 detection process and the prize ball discharging device are related to each other and become complicated. Therefore, a detailed processing procedure is shown in FIG. 11 and will be described below based on this.

When the processing is started by turning on the power or generating an interrupt, first, a safe memory for storing the number of winning balls and various registers are initialized before detecting a winning ball (routine R1). The number of discharge spheres (hereinafter, referred to as radix base) for each downflow path in 20 is determined (routine R2).

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 'switches 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 discharge solenoid 1 side as shown in Table 1, it becomes possible to balance the supply of spheres 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 the control of the experiment, n smaller by “1” than the set number n
It is necessary to change the control signal for the solenoid 21 that operates the flow-down preventing member 22 when the discharge sensor detects the first ball.

When the emission base setting process (routine R2) ends,
Wait for 2 seconds of idle time (Routine R
3), proceed to the next routine, and determine whether the safe sensor has been turned on for a certain period of time R4). Here, if it is determined to be no (no), it is determined whether or not the output of the safe sensor has risen in the next routine R5, and if it is no, the process proceeds directly to routine R7. On the other hand, if it is determined in any of the routines R4 and R5 that the answer is yes, that is, that there is a safe sphere, the routine proceeds to the routine R6 to increase the storage of the safe memory in the CPU by "1", and then proceeds to the routine R7.

In the routine R7, it is determined whether or not the number in the register for storing the processing number is "1".
Jump to the discharge ball detection process indicated by. Then
Since the process number register has been reset to "0" by the initial setting in the routine R1, no is determined in the first determination in the routine R7, and the process proceeds to the next routine R8. Here, it is determined whether or not the number in the processing number register is “2”,
If the answer is yes, the process jumps to the post-processing indicated by the reference symbol B. However, in the first judgment, the result is no, as in the routine R7, and the process proceeds to the fraud detection processing in the routine R9.

FIG. 12 shows an example of a specific procedure of the fraud detection processing. In this process, first, it is determined whether or not there is a rising edge of the output signal of the discharge sensor 1 (routine R91).
Here, if it is determined that there is a rising edge, that is,
The routine proceeds to the routine R92, where "1" is added to the illegal counter 1. Then, in the next routine R93, it is determined whether or not the value of the illegal counter has exceeded 2. If the determination is NO in each of the routines R91 and R93, the routine proceeds to a routine R94, where it is determined whether or not there is a rising edge of the output signal of the discharge sensor 2. If the determination is yes, that is, if there is a rising edge, the routine proceeds to routine R95, where "1" is added to the illegal counter 2, and it is determined in the next routine R96 whether the value of the illegal counter 2 has exceeded 2.

When one of the routines R93 and R96 is determined to be YES, the process proceeds to a routine R97. That is, the fact that one of the values of the counters 1 and 2 exceeds "2" means that there is a discharge ball despite the discharge solenoid being turned off, that is, the stopper of the prize ball discharge device is incorrectly removed. Either the discharge solenoid has failed or the stopper has come off. This is because, in the normal state, the discharge solenoid is turned on as described later (routine
R14), the process number is changed to "1" in the routine R15, the process returns to the routine R5, and the process shifts from the routine R7 to the prize ball discharge process A.
2 is not counted up to 2 or more.

If one of the routines R93 or R96 NO is determined to be yes, the routine proceeds to the routine R97, in which the motor for hitting the ball is stopped, the fraud warning display lamp 114 is turned on (routine R98), and the speaker 120 issues a warning. A sound is generated and the process ends (routine R99). If the game store clerk inspects the solenoid of the prize ball discharge device while watching the fraud warning display, it can be easily determined whether the fraud has been made or the solenoid has failed.

It should be noted that the routine proceeds to routine R94 after it is determined that no is present in one of the routines R91 and R93, and the routine R94 or R93
If NO is determined in any of R96, routine R10
Proceed to.

In the routine R10, it is determined whether or not the storage in the safe memory is "0". When the winning memory is incremented in the routine R6 and the routine proceeds to the routine R10, the determination is YES, and the process proceeds to a series of processes including the routines R11 to R15.

That is, if there is a winning memory, the safe lamp (prize ball lamp 111) is first turned on in the routine R11, then the discharge base 1 determined in the routine R2 in the discharge register 1 in the routine R12 (see Table 1) and the routine R13. The discharge radix 2 is loaded into the discharge register 2 respectively. Then, after turning on the discharge solenoids 1 and 2 in the routine R14, "1" is set in the process number register in the routine R15,
Return to routine R5. Then, the above processing is repeated again. This time, since the processing number register is set to "1", the determination is YES in the routine R7, and the routine jumps to the discharge ball detection processing A.

In the discharge ball detection processing A, first, it is determined whether or not the output of the discharge sensor 1 has risen (routine R2). If NO, the process directly proceeds to the routine R25, and it is determined whether or not the output of the discharge sensor 2 has risen. And the routine
When the rising of the sensor output is detected in R21, the process proceeds to a routine R22, in which the content of the discharge register is subtracted by "1", and then, in the next routine R23, whether or not the value of the discharge register has become "0". judge. If the determination is yes, the discharge solenoid is turned off (R24). Immediately after the discharge is started, the determination is NO in the routine R23, and the process proceeds to the routine R25.

In the routines R25 to R28, the same processing as the processing relating to the discharge system 1 (routines R21 to R24) is performed for the discharge system 2, and then the routine proceeds to the routine R29. In the routine R29, it is determined whether or not the sum of the values of the discharge registers 1 and 2 is "0". If NO, that is, if it is not "0", the routine returns to the routine R5 and the above procedure is again performed. Thus, routine R2
If it is determined in step 9 that the prize ball discharging device has finished discharging a predetermined number of prize balls, the process proceeds to a routine R31, in which the safe solenoid is first turned on.

This enables the winning ball processing device to capture the next winning ball. After the safe solenoid is turned on, a timer for the safe solenoid (for example, 100 ms) is set in a routine R32, and a timer for a wait time (for example, 600 ms) is set in a routine R33. then,
After resetting the illegal counters 1 and 2 to zero in the routine R34, the content of the process number register is changed to "2" in the routine R35, and the process returns to the routine R5.

Then, the routine jumps from the routine R7 to the post-processing B. At first, it is determined in a routine R41 whether or not the safe timer has expired. If NO, the safe solenoid is turned off. If YES, the safe solenoid is turned off (routine R42). Proceed to. In the routine R43, it is determined whether or not the time of the wait timer has expired. If NO, the process returns to the routine R5 and the above processing is repeated again. If YES, the winning memory of the safe memory is subtracted by "1" in the routine R44, and then The process number register is reset to "0" and the process returns to the routine R5 (routine R45).

FIG. 13 shows the timings of various signals when the prize ball processing and the prize ball discharge processing are executed according to the above-described procedure.

That is, in response to the rise of the output of the safe sensor, the winning memory of the safe memory becomes "1", the safe lamp is turned on, and the discharge solenoids 1 and 2 are turned on. Then, the discharge of the prize balls is started, the output of the discharge sensors 1 and 2 changes for each discharged ball, and a predetermined number (radix-1 in Table 1)
Is reached, a solenoid demagnetization command 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 discharge start of the next prize ball is waited until the timer expires (600 ms).

Since the set time of the safe solenoid timer is set to 100 ms, the stopper 47 driven by the safe solenoid 46 is raised for 100 ms, and this stopper 4
The winning balls blocked by 7 can be reliably discharged, and the system can promptly shift to a state for waiting for the winning balls next flowing into the winning ball processing device 40.

In addition, since the set time of the discharge wait timer is set to 600 ms, the state of the ball in the guide gutter 11 can be stabilized after the discharge is completed, and then the next discharge can be performed, and the accuracy of discharge is guaranteed. .

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. 14, various display lamps L, discharge solenoids 21 and safe solenoids 46 connected between the power supply voltage terminal VA and the ground point are provided.
Is the switch transistor connected in series with them
It is driven by turning on / off Tr ₁ , Tr ₂ , T _3, etc., but in the above embodiment, in parallel with the discharge solenoid 21, for example, 24 higher than the peak value of the power supply voltage.
Zener diode Dz with zener voltage like V
Is connected.

For this reason, when a voltage obtained by full-wave rectification of AC 24 V AC is applied to the power supply voltage terminal VA, turning off the transistor Tr ₂ usually causes the solenoid to completely demagnetize as shown in FIG. 15 (A). When the zener diode Dz is connected in parallel with the solenoid coil, which has been required for t ₁ hours, this acts as the forced energy release means, and the demagnetization time of the solenoid is reduced. That is, the fifteenth
Figure (A) and the hatched portion of the area S ₁ and S ₂ and is equal such time t ₂ of (B) is the demagnetizing time when put Zener diode Dz. This results in a Zener voltage
In the case of 24V, the degaussing time is reduced to about one half compared with the case where the Zener diode is not inserted, and the response speed of the flow preventing member 22 in the prize ball discharging device 20 is correspondingly increased.

Incidentally, zener diode Dz and a diode D _1, which in series with the reverse direction in Figure 14 is used to hold the transistor Tr ₂ from the counter electromotive force of the solenoid,
Switch transistor a similar protection Tr ₃ diode D ₂ Safe solenoid 46 is provided. However,
Since the safe solenoid 46 does not require much faster response than the discharge solenoid 21, the Zener diode
Dz is unnecessary.

In the above embodiment, the safe sensor (winning ball detector)
A detecting piece 43c for operating the 91 is provided in the swingable ball processing device 43, and the detection of the swing of the ball processing device 43 indirectly detects a winning ball, but is not limited thereto.
