[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for preventing illegal ejection of stored balls in a pachinko gaming machine, and more particularly, to a game machine in which a pachinko ball stored on the back side of a machine is used as a prize ball for winning a game. Dish) side, while
In a gaming machine which can be discharged outside the machine as a return ball (return ball) by a ball removal operation, it is possible to switch the discharge path of the ball and to prevent illegal discharge of the ball extracted as a return ball. The invention relates to a device for preventing unauthorized discharge.

[0002]

2. Description of the Related Art In this type of gaming machine represented by a pachinko machine and an arrangement ball machine, a ball is fed from a ball plate to a firing position by a ball-feeding / launch control operation for each ball started based on a game operation. The required pachinko game can be played by launching the game ball into the game board. Then, the balls stored in the ball storage and discharge path section on the back side of the machine are paid out by the prize ball payout device in response to the winning conditions during the game (such as generation of a safe ball and establishment of a symbol combination score by entering the ball). Each operation is paid out as a predetermined number of prize balls, and is supplied to the upper and lower ball dishes from a predetermined prize ball path. On the other hand, when it is necessary to remove a considerable amount of stored balls in the ball storage / discharge path due to handling of the gaming machine, generally, an operation rod is inserted from an operation hole formed on the front side of the front frame to insert the operation rod. With the switching valve provided at the branch connection between the prize ball path and the ball-extraction path held in the ball-extraction state (ball-return position), the stored From the outside of the aircraft. The operating rod is a wire-like material having a knob, and is managed by the hall manager. However, a straight material that is easily available can be sufficiently substituted.

[0003] In such a pachinko gaming machine, apart from paying out prize balls, as a form in which all stored balls can be paid out by a ball removing operation, the prize ball payout device generally uses an electric motor for each winning condition. Tools (solenoids and motors)
The electric drive type that pays out and counts the prize balls while controlling the rotation of the ball feeder facing the ball path by the drive control of the ball is used. In the ball punching device, the detection input of the switch operated by the operation rod is used. An electric type is used in which the switching valve is switched to a ball release (return) position to be held and pulled out by drive control of an electromagnetic solenoid based on the above. And as an embodiment of both devices, at the side edge of the mechanism set board on the back side provided with a window for game board inspection, a prize ball payout device is installed in accordance with the downstream portion of the ball storage and discharge path section,
Further, a ball-pulling device is installed at a branch connection between the ball-pulling path and the ball-pulling path communicating with the downstream of the ball-pulling-out device, and based on the detection input of the switch in the ball-pulling operation, the switching of the switching valve and the prize. Under the condition for releasing the ball dispensing device, all the withdrawn balls can be released.

[0004] In addition to the operation rod, the ball punching device can detect a switch operation by a fingertip operation on the back side of the front frame opened from the outer frame.
Also, in both devices, as a ball-pulling control process in the electronic control device, the detection input of the switch is enabled only once,
After the ball release operation, the power is turned on again or a reset input operation related to the electronic control unit is performed as a normal restoration process. Unless this processing is performed, the subsequent detection input of the same switch is invalidated and the ball is set to be impossible to remove. Under the circumstances, the electric tool and the electromagnetic solenoid are set so as to automatically return after a predetermined time elapses based on a timer setting condition in the electronic control device with respect to the detection input of the switch for removing the ball.

[0005]

By the way, in recent pachinko gaming machines, it has been demanded that, in addition to paying out the stored balls on the back side of the machine as prize balls, it can be paid out as rental balls for games. In many cases, the above-mentioned electric-type prize ball payout device is used, and the ball punching device is incorporated in the lower part correspondingly. In such an embodiment, it is easy to separately pay out the prize balls and the rental balls, and even if all the stored balls can be withdrawn, the illegal extraction acquisition of the stored balls is permitted. There was a big problem. That is, in the present situation, the ball-pulling switch is easily operated and detected even with a wire-shaped material other than the operating rod, and based on this detection input, both devices are operated in a ball-pulling state and a ball-pull-out state. You. For this reason,
A fraudulent person familiar with the configuration of the gaming machine and the configuration of both devices, etc., intrudes into the above-mentioned prize ball path from a supply port for communicating a linear fraudulent product to the upper ball dish in a posture pretending to be a normal game, and The switch valve is inserted into the upper side of the ball removing device while being operated, and the switching valve is restrained and held at the dispensing position. In this case, when the switch is illegally detected and operated, all the stored balls are discharged from the prize ball dispensing device in the ball release and released state, and then discharged to the prize ball path by the above-described switching valve. It is fed to the upper or lower bowl.

Therefore, in many pachinko gaming machines equipped with the above-mentioned electric-type prize ball dispensing device and the ball removing device in combination, all the stored balls are out of the machine by a normal ball removing operation. Although it has a convenient function of being able to pull out the ball, it has an inherent disadvantage that it can be obtained by illegal ball pulling as described above, and this cannot be prevented suitably. As a result, even if only the illegal withdrawal by one effective detection operation of the switch is permitted, hundreds of stored balls are actually withdrawn, and if the number of gaming machines increases, the quantity that can not be neglected at all ( There was a problem that the hall side was seriously damaged due to the storage ball of (amount). By the way, the illegal ball removal mentioned above is performed skillfully without even the neighboring player noticing, and the hall side seems to detect abnormalities after checking the operation status of each unit by computer management It is in the current situation.

[0007]

SUMMARY OF THE INVENTION An object of the present invention is to newly solve the above-mentioned problem by providing a prize ball in a ball switching discharge section mounted below a ball payout section of a mechanism set board on the rear side of the machine. It is an object of the present invention to provide a device for preventing illegal discharge of stored balls in a pachinko game machine, which can switch the discharge between a ball and a return ball, and can prevent the prize ball from being obtained by illegal act of removing the ball. .

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems and to achieve the initial object, the present invention provides a method of dispensing pachinko balls stored in a prize ball storing and discharging portion of a mechanism set board mounted on the back side of the machine. The ball can be discharged from the prize ball discharge path to the player side as a prize ball for the winning of the game under the condition that the ball can be paid out, while the ball can be discharged from the ball release path to the outside as a return ball at the time of the ball release operation. In a pachinko game machine, a rotary electromagnetic solenoid having a rectangular outer body is installed in a predetermined direction in a ball switching discharge section provided at a predetermined portion below a ball payout section of the mechanism set board, and assembled in the outer body. The rotatable shaft inserted into the exciting force generating unit is rotatably supported, and a part of the rotatable shaft extends as a fulcrum shaft outside the outer body.

The illegitimate discharge prevention device comprises a rotary electromagnetic solenoid incorporated in a case body, and a switching valve connected to a tip of a rotating shaft of the electromagnetic solenoid and positioned at a branch point between a ball payout path and a ball return path. And a maintenance switch capable of detecting that the switching valve is switched and held in a ball-pullable state, and is miniaturized in one case unit. In a state where the illegal discharge prevention device is assembled and set in the installation section, the ball entrance formed in the case body is in communication with the ball passage of the ball exit section, and the ball exit path branched from the ball entrance is awarded. The ball return path branched off from the ball entrance path is aligned with the ball discharge path side and is aligned with the ball discharge path side. Then, in the non-excited state of the electromagnetic solenoid, the switching valve is held in the first state, that is, the state in which the ball entrance path and the ball discharge path are communicated by the biasing force applied to the switching valve, The pachinko ball dispensed from the ball dispensing unit is discharged from the ball passage and the ball entrance to the ball dispensing road side, and is discharged to the player side as a prize ball via the prize ball discharge path. Further, in the excited state of the electromagnetic solenoid by a required ball-pulling operation, the switching valve causes the switching valve to communicate with the second state, that is, the ball entrance path and the ball return path, due to the rotational displacement of the rotary shaft of the solenoid. The pachinko ball discharged from the ball dispensing unit is held in the posture in which the ball is released, and is discharged from the ball passage and the ball entrance to the ball return road side, and is discharged outside the machine as a return ball via the ball release path.

For example, when the locking member 70 is held at the unlocked position, as shown in FIG. 11, the connecting pin 88 engages with the cam edge 75a, and the movable regulating member 87 Is the sending gutter 4 at the swing end side.
The posture is held in the tilt restriction state extending to the position c. As a result, the pachinko ball that flows down along the discharge gutter 4c abuts on the restriction valve 89 of the movable restriction member 87 held in the tilt restriction state, and the outflow from the transmission gutter 4c is restricted. That is, when the locking member 70 is held in the unlocked position and the winning ball dispensing device F is removed from the concave chamber 25, the outflow of the pachinko ball from the delivery gutter 4c is suitably restricted. I have. On the other hand, when the locking member 70 is displaced to the lock engagement position, as shown in FIG. 10, the connecting pin 88 is engaged with the engagement port 80, and the movable regulating member 87 swings. The posture of the end side is held in the regulation released state in which the end side is retracted from the delivery gutter 4c. As a result, the delivery gutter 4c

In the second electronic control unit 22, one detection signal of the switch 14 is effectively input, and the electromagnetic solenoid 48 for switching and then the solenoid 34 for dispensing are switched by the ball release command for each time. (For example, 50 seconds and 45 seconds), and the input signal of the reset switch 60 is set so that the next ball removal detection signal can be input effectively.

[0033]

In the pachinko machine of the present embodiment constructed as described above, during the assembly and manufacture of the pachinko machine, the device G for preventing illegal storage of the stored balls and the prize ball dispensing device F are connected to the mechanism set board C. Can be fixedly set by a one-touch operation in the recessed chamber portion 25 formed at the same time, and extremely simple and easy assembling is possible. In other words, the illegal discharge prevention device G only needs to align and position the locking pieces 65, 65 above the slide grooves 66, 66, and only slide down in this state. Is the slide groove 66
The illegal discharge prevention device G is fixedly set in the concave chamber portion 25 by fitting into the inside. The prize ball dispensing device F has a configuration in which the unauthorized discharge prevention device G is fixedly set in the concave chamber 25.
The locking piece 67 is fitted into the locking concave portion 69 of the unauthorized ejection prevention device G, and the locking member 70 is fixedly set to the concave chamber portion 25 only by rotating and displacing the locking member 70 to the lock locking position. As a result, the prize ball dispensing device F and the unauthorized discharge prevention device G are fixedly set in the recessed portion 25 in a state of being vertically connected. Since the locking member 70 is displaced to the lock engagement position, the movable regulating member 87 is held in the posture in the unregulated state, so that the pachinko ball flowing down along the sending-out gutter 4c receives the award ball payout. It flows into the ball passage 28 of the device F and reaches the ball feeder 32 in the ball payout unit 30.

In the pachinko machine according to the present embodiment configured as described above, the card unit E is mounted on the installation frame in the game hall.
It can be set up and used for games. Then, by inserting a card into the card unit E and lending a ball on the front side of the machine, the lending ball dispensed from the winning ball dispensing device F of the mechanism set board C can be supplied to the upper ball plate side and accommodated. By performing a game operation (hitting ball firing operation) under this condition, the game balls sent one by one to the launch position in the machine can be launched into the game board to develop a required game. Then, the out ball generated during the game is discharged from the discharge path 2 of the mechanism set board C to the outside of the machine, and the safe ball is introduced into the safe ball detection processing device D from the processing path 3 to detect the stop of each ball one by one. After the processing, the ball is discharged to the outside of the machine, and in response to the safe ball detection processing, a predetermined number of prize balls are paid out from the prize ball payout device F and supplied to the upper ball plate or the lower ball plate. Then, the ball stored in the ball storage / discharge path section 4 can be withdrawn in the released state of the prize ball payout device F and discharged to the outside of the machine from the ball pull-out path 9 by the operation when ball removal is necessary.

A description will now be given, with reference to the drawings, of the ball discharging operation of the prize ball dispensing device F implemented in such a pachinko machine and the device G for preventing illegal storage of stored balls according to the present embodiment. First, regarding the payout of the loaned ball, the ball presence detection input condition of the switch 11 for the loaned ball is provided.
The ball payout unit 30 is activated based on the operation of the ball lending switch 59 with the insertion of the card. That is, the card reader 2 responds to the operation input of the switch 59.
3, based on a control process between the interface board 24 and the second electronic control device 22 and a ball lending command,
The ball dispensing unit 30 of the prize ball dispensing device F is operated to control the electromagnetic solenoid 34 (excitation and demagnetization), switch the restriction piece 36, detect the presence of a ball of the first and second detectors 38 and 39, and feed the ball. By the pitch rotation of the body 32, a predetermined number of balls (for example, 25 lending balls for a lending amount of 100 yen) are paid out one ball at a time, and the first prize ball path is passed from the ball payout path 43 in the unauthorized ejection prevention device G. 5 and is supplied from the supply port 6 to the upper bowl. 5 and 15 (a) show the specific state of discharge of the lent balls, all the lent balls are ball feeders 3
After being released from the receiving portion 33, the ball is discharged through the ball discharge path 4 along the switching valve 49 which is counted and detected by the second detector 39 and passes through the ball entrance path 40 and is held at the upright discharge position.
After being passed out to the third side, it is discharged to the first prize ball path 5.

The payout of the prize ball to the safe ball is performed every time the safe ball is detected by the safe ball detection processing device D shown in FIGS.
0 is activated. That is, from the processing path 3 to the path 16
Under the condition that the switch 17 detects the safe ball stopped at the detection position by the stopper 18b of the regulation processing member 18 through the control processing member 18, and the first and second electronic control devices 21 and 22 respond to the detection input. Based on the processing of the safe ball signal and the prize ball signal and the payout command, the ball payout unit 30 is operated in the same manner as described above (see FIGS. 5 and 15A), and the control operation of the electromagnetic solenoid 34 is performed. And regulating piece 36
A predetermined number of balls (for example, 5 to 15 prize balls) are paid out one by one by the pitch rotation of the ball feeder 32 according to the switching of the ball feeder 32, and the first prize ball path from the ball entrance path 40 and the ball discharge path 43. 5 and is supplied from the supply port 6 to the upper ball dish or from the second prize ball path 7 to the lower ball dish. Then, based on the time when the predetermined number of last payout balls that have been paid out are counted and detected by the second detector 39, the payout operation of this time is terminated and the electromagnetic solenoid 3 is turned off.
The ball feeder 32 is stopped and held in accordance with the demagnetization of No. 4 and the return of the regulating piece 36. In the safe ball detection processing device D after the payout is completed, the electromagnetic solenoid 19 is actuated once (excitation and demagnetization) based on a safe ball release command from the second electronic control device 22, thereby restricting the processing member. In accordance with the switching of 18, the safe ball at the detection position is released and discharged outside the machine,
The next safe ball enters the detection position and stops (see FIG. 3).

On the other hand, the ball switching discharge unit 4 of the illegal discharge prevention device G is used to remove the stored ball from the ball based on the ball removal operation.
7 and the ball payout unit 30 of the prize ball payout device F are sequentially operated. That is, when the switch 14 for removing balls is operated, the ball switching / discharging portion 47 is switched based on the control processing by the second electronic control unit 22 for the detection input and the command for removing balls. Solenoid 48
The switching valve 49 is switched to the tilt return position and is held at the same time as the rotation of the rotation shaft 54 due to the excitation (FIGS. 5 and 15B).
reference). Next to this (for example, after 1.5 seconds), the ball payout unit 30
Is released, and the restriction piece 36 is magnetically displaced by the excitation of the electromagnetic solenoid 34 to release the ball feeder 32. As a result, under the continuous free rotation of the ball feeder 32 while receiving the ball in the ball passage 28, the stored ball in the ball storage / discharge path portion 4 discharged one by one is deflected by the switching valve 49. While being guided, it passes through the ball return path 44 and is withdrawn from the ball removal path 9 to the outside of the machine. Then, at the end of the ball removal command after the elapse of the set time, the ball dispensing section 30 is returned to its original state, and the demagnetizing of the solenoid 34 causes the regulating piece 36 to return to its displaced state to stop and hold the ball feeder 32. Next to this (for example, after 3.5 seconds)
The ball switching discharge portion 47 is returned to its original state, and the rotating shaft 54 becomes free due to the demagnetization of the solenoid 48, and the torsion spring 55
The switching valve 49 is returned to the original upright dispensing position under the urging force of FIG.
5 (a)).

In the above-described ball removal operation, even if a slight ball flow delay occurs in the ball storage / discharge path section 4, the entire ball can be accurately removed by setting the excitation time of both the solenoids 34 and 48. . And after removing the ball,
By operation of the replenishment equipment, a new considerable amount of balls are stored in the ball tank 4a
Into the ball passage 2 of the ball dispensing section 30
The ball is passed (accommodated) from a predetermined position (the position where the ball feeder 32 is received) in the ball storage / discharge path section 4 so that the above-mentioned loaned ball and prize ball can be paid out. Incidentally, as another example of setting in the second electronic control device 22 relating to the prize ball payout device F and the illegal storage device G of the stored ball according to the present embodiment, the ball lending operation signal can be input after the prize ball payout command is completed. Input is not possible after the ball-pulling operation signal is input
(Invalid). The prize ball payout signal can be input after the end of the ball lending command, and is disabled (invalid) after the input of the ball removal operation signal. The ball-pulling operation signal can be input only once after the end of the instruction to pay out the loaned ball and the prize ball.

On the other hand, in the device G for preventing illegal storage ball discharge according to the present embodiment, as a unique function of the device, illegal acquisition of the storage ball to be discharged to the outside by the ball removal operation (extraction to the upper ball tray side). As a countermeasure against this, the ball switching switch 47 can be held in the ball-pulling state by detecting the ball-pulling switch 14 with the operation rod inserted through the operation hole of the front frame B. In this case, even if an illegal operation is performed by the illegal operation on the front side of the machine and the illegal object is intruded from the supply port 6 to the back side, and the skillful manipulation is performed, the stored balls are preferably prevented from being discharged to the ball payout path 43 side. I have. Before the ball discharging operation of the prize ball discharging device F, as shown in FIG. 15A, the switching valve 49 is displaced to the upright discharging position and the pressing piece 9 is moved.
2 is separated from the switch button 91, and the condition that the maintenance switch 90 is turned off and the switching valve 49 is not detected is input to the second electronic control device 22.

When the ball removing switch 14 is operated by the operating rod inserted through the operation hole of the front frame B, the switching electromagnetic solenoid 4 in the ball switching discharge section 47 is operated.
8 is excited, and the switching valve 49 is switched to the tilt return position and held. Then, when the pressing piece 92 presses the switch button 91, the maintenance switch 90 is turned on and the ball payout unit 30 enters the payout release operation state under the condition that the switching valve 49 is detected, As appropriate after the start of the operation of the switching electromagnetic solenoid 48, the dispensing electromagnetic solenoid 34 is excited to start dispensing the stored balls (see FIG. 15B). At this time, the switching valve 49
Is held at an inclined return position where the ball return path 44 is closed and the ball return path 44 is opened,
The stored balls discharged from 0 are guided to the ball return path 44 side, and then are withdrawn to the ball release path 9 (see FIG. 15B).

Then, in the above-described state of withdrawal of the stored sphere, the linear illicit material is caused to enter the first prize ball path 5 from the supply port 6 and to be inserted into the ball dispensing path 43 side. When the switching valve 49 contacts the switching valve 49, the switching valve 49 is swung clockwise in the drawing. As a result, the switching valve 49 held at the tilt return position slightly swings and displaces against the exciting force of the electromagnetic solenoid 48, whereby the pressing of the pressing piece 92 against the switch button 91 is released. That is, since the maintenance switch 90 is turned off, the ball dispensing unit 30 is turned off under the condition that the switching valve 49 is not detected.
Is disengaged, the dispensing electromagnetic solenoid 34 is demagnetized, and the dispensing of the stored balls is stopped. That is, even if the switching valve 49 is forcibly displaced to the upright dispensing position by an improper object, the dispensing electromagnetic solenoid 34 is demagnetized, and the ball feeder 32 becomes unrotatable by the restricting piece 36. Because the payout of the stored balls is restricted, only one or two balls that were in the ball entrance 40 can be extracted.

As an operation setting condition of the dispensing electromagnetic solenoid 34, N times (for example, three times) illegal ball removing operations are performed.
After the maintenance switch 90 is turned ON → OFF, the solenoid 3
4 is set to be deactivated, the switching valve 49 is released when the first unauthorized operation by the unauthorized object is released.
Swings back to the inclined return position under the operation of the switching electromagnetic solenoid 48, and the pressing piece 92 turns the maintenance switch 90 ON accordingly. That is, the maintenance switch 90
Is the condition that the switching valve 49 is detected, the electromagnetic solenoid 48 for switching is restarted, and the ball is released from the stored ball to the ball return path 44 and the ball release path 9 ( FIG. 15 (b)). Further, when the switching valve 49 is swung again by an illegal object that has entered the first prize ball path 5 from the supply port 6, the maintenance switch 90 is turned off, and the condition that the switching valve 49 is not detected is established. The dispensing electromagnetic solenoid 34 is demagnetized and the dispensing of the stored ball is stopped.
Therefore, the ball entry 4
Only one or two balls that were in 0 can be extracted. Similarly, in the third illegal operation, only one or two balls can be extracted. Therefore, only a few stored balls can be extracted by the third illegal operation. After the set number of unauthorized operations are performed on the dispensing electromagnetic solenoid 34, the ON / OFF of the maintenance switch 90 is performed.
Regardless of the FF state, the electromagnetic solenoid 34 is kept in the operation stop state, and the next ball-pulling detection signal is set to be validly input only on the premise of the input condition of the reset switch 60.

In this embodiment, the case where the "a contact" is used as the maintenance switch 90 has been described.
2 while the switch button 91 is being pressed.
A “b contact” that is in the FF state can be used. In this case, it is set so that the tilt return position of the switching valve 49 is detected when the switch 90 is in the OFF state.

In the pachinko machine according to the present embodiment, the prize ball dispensing device F and the device for preventing the illegal discharge of the stored balls are appropriately set on the installation frame in the game hall as described above and used for the game. G can be easily and easily removed from the recess 25 by a one-touch operation. In other words, if the locking member 70 is rotated to the unlock position to release the engagement between the engagement plate 75 and the engagement piece 68, the prize ball dispensing device F is pulled out to the upper front side. The dispensing device F can be easily removed. Further, in a state where the winning ball dispensing device F is detached from the recessed portion 25, if the illegal ejection preventing device G is pulled upward, the illegal ejection preventing device G can be easily removed. Moreover, the locking member 7
In the state where 0 is held in the unlock position,
Since the movable restricting member 87 of the ball flow restricting device 85 is held in the posture in which the slant is restricted, even if the pachinko ball remains in the ball storage / discharge path 4, for example, the pachinko ball flows out of the delivery gutter 4c. I will not do it.

Further, in the pachinko machine of the present embodiment, as described above, the prize ball dispensing device F and the illegal discharge preventing device G can be extremely easily and easily removed. The disassembly work for each part can be speeded up and rationalized.

[0046]

[Modification] FIG. 17 illustrates a modification in which the ball entrance path 40, the ball discharge path 43 and the ball return path 44 in the device for preventing illegal discharge of stored balls G are formed in an inverted Y-shape. A switching valve 49 disposed on the 48 rotation shaft 54 is disposed so as to be tiltable left and right. When paying out the lending balls and paying out the prize balls, the switching valve 49 is held at the ball dispensing position tilted rightward to guide the pachinko balls from the ball entrance path 40 to the ball dispensing path 43 side. Also, when removing the stored ball, the electromagnetic solenoid 4
The switching valve 49 is held at the ball return position where the switching valve 49 is tilted to the left under the rotation of the rotation shaft 54 by the excitation of 8, and the stored balls are guided out from the ball entrance 40 to the ball return path 44 side.

[0047]

As described above, according to the apparatus for preventing illegal storage of a stored ball in a pachinko gaming machine according to the present invention, a ball payout path communicating with a prize ball discharging path and a ball return path communicating with a ball removing path. Since the switching valve disposed at the branch portion of the switching valve is disposed directly connected to the rotary shaft of the rotary electromagnetic solenoid, the operation system of the switching valve is simplified, and the posture of the switching valve is changed between the first state and the second state. There is an advantage that the operation of the displacing switching valve is performed extremely smoothly. In addition, since the exciting force generating portion and the rectangular outer body of the electromagnetic solenoid are configured to be small, the size and weight of the unauthorized emission prevention device itself can be reduced, and the handling becomes easy. Furthermore, with the reduction in size and weight of the unauthorized emission prevention device, the installation site on the mechanism set panel side can be made smaller and narrower, which increases the degree of freedom in designing the entire prize ball ejection path and makes it easier to install other equipment. And other beneficial effects.

Further, in the device for preventing illegal storage of a stored ball in a pachinko gaming machine according to the present invention, the switching valve held in the second state (ball return position) is detected by the maintenance switch disposed in the ball switching discharge section. The operation of the ball payout unit is controlled based on the detection condition of the switch. In other words, under the condition of detection of the maintenance switch by the switching valve being held in the original second state, the ball dispensing unit can be operated to discharge the stored ball as a return ball to the outside of the machine. Under the non-detection condition of the maintenance switch due to the switching valve being displaced to the first state (payout position) side, it becomes possible to stop the ball payout portion and to make it impossible to pay out the stored balls. Therefore, even if, for example, an illicit object can be made to enter the prize ball path from the supply port communicating with the upper ball tray, and the switch valve can be maintained in the first state while being manipulated, the switch valve is in the second state. Since the state is not in the state, the maintenance switch is in a non-detection condition, and there is an extremely beneficial effect that the stopping of the ball dispensing unit suitably prevents illegal acquisition of the stored ball.
