[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prize ball discharging device for a pachinko game machine, and more particularly, to a game machine capable of developing a pachinko game in a game board, in which a pachinko ball stored on the back side of the game machine is used for prize balls. The present invention relates to a prize ball discharge device which can be supplied to a ball tray side and can be pulled out of the machine as a return ball (return ball) by a ball removal operation.

[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]

The prize ball dispensing device is installed at a required portion downstream of the ball storing and discharging path, and the ball removing device is disposed immediately adjacent to the downstream portion of the prize ball dispensing device. It is installed, and the respective devices cooperate with each other in close relation, so that the stored ball can be paid out to the upper ball tray or the lower ball plate side as a prize ball, or can be withdrawn outside the machine. However, despite these prize ball payout devices and ball punching devices being installed vertically and being controlled in conjunction with each other, they are individually designed and manufactured as separate devices, The disadvantage is that the production cost increases. Also, when the prize ball dispensing device and the ball punching device are connected vertically, it becomes quite large, so on the mechanism set panel, a large installation area must be secured based on the external size of both devices. In addition, the design of the entire prize ball discharge path was subject to some restrictions. Further, in the assembling work on the mechanism set board, since the prize ball payout device and the ball removing device must be separately positioned and set and installed, the assembling becomes troublesome and takes time, and the assembling of the gaming machine is performed. This has been an obstacle to cost reduction and rationalization.

In recent years, in response to the demand for pachinko gaming machines, in addition to paying out the stored balls on the back side of the machine as prize balls, it has been demanded that they 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 form of both devices, etc., intrudes into the prize ball path from a supply port for communicating a linear fraudulent object to the upper ball dish in a posture pretending to be a normal game. Then, while skillfully manipulating, the switch valve is inserted into the upper side of the ball removing device to hold the switching valve in the dispensing position. Under this condition, 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.

Accordingly, in many pachinko gaming machines equipped with the above-mentioned electric-type prize ball dispensing device and 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.

[0008]

DISCLOSURE OF THE INVENTION The present invention has been proposed to solve the above-mentioned problem suitably, and a ball dispensing operation for dispensing a ball in one case set on a mechanism set board on the back side of the machine. Unit and a switching discharge unit for switching the passage of the ball, to reduce the size and simplification of the whole device, and to simplify the implementation for the mechanism set panel, and to make the switching discharge unit illegal. The purpose of the present invention is to provide a prize ball discharge device in a pachinko gaming machine that can prevent the ball from being held in a ball dispensing state by a manual operation and prevent the acquisition and acquisition of a stored ball by an illegal ball-pushing action from the front side. I do.

In the case body formed with a ball entrance path communicating with the ball storage / discharge path section, a payout path communicating with the prize ball path, and a return path communicating with the ball removal path, rotation stop control is performed by the electric tool. A ball dispensing section having a rotary ball feeder is disposed at a position facing the ball entry path, and a switching discharge section having a switching valve switched and held by another electric tool is connected to the dispensing section and return path. And the prize ball discharging device can be handled as one unit member that is reduced in size and simplified by incorporating the ball discharging portion and the switching discharge portion in the case body. Therefore, when assembling to the mechanism set board, the case body can be easily and easily installed at a predetermined position on the downstream side of the ball storage / discharge path simply by positioning and setting the case body and fixing it with screws or the like. Work can be simplified and streamlined.

In the switching discharge section, when the switching valve is held at the dispensing position, the guide preventing piece attached to the switching valve extends to the dispensing path in a state capable of receiving the dispensing ball and guiding the dispensing. Put out. When the switching valve is held at the return position, the guide preventing piece attached to the switching valve extends in an arc shape to the discharge path and substantially closes and blocks the outlet surface of the discharge path. Therefore, even if an illegal object is intruded from the ball tray side to the back side by an illegal operation on the front side and skillfully manipulated, the guide preventing piece prevents the illegal object from entering the payout path, so that the ball removing operation is performed. In some cases, it becomes impossible to restrain the switching valve, which should be held at the original return position, at the dispensing position, and it is possible to suitably prevent the illegal acquisition of the stored ball withdrawn as the return ball.

That is, under the condition that the switch 17 detects a safe ball that has passed through the processing path 3 into the path 16 and has been stopped at the detection position by the stopper 18b of the regulating processing member 18,
The second and first electronic control units 21 and 22 for 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 35 is operated in the same manner as described above (see FIGS. 11A and 11B), and 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 37 in accordance with the control operation of the solenoid 39 and the switching of the regulating piece 41, and the switching valve is provided from the payout path 30. Through the guide prevention piece 55 of 52, the ball passes through the first prize ball path 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 point in time when the predetermined number of the last awarded balls that have been paid out are counted and detected by the second detector 44, the payout operation of this time is terminated, and the ball is fed according to the demagnetization of the electromagnetic solenoid 39 and the return of the regulating piece 41. The body 37 is stopped and held. 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. Following the switching of 18, the safe ball at the detection position is released and discharged outside the machine, and the next safe ball enters the detection position and stops.
(See FIG. 3).

On the other hand, in the case of removing the stored ball, the switching discharge section 47 and the ball payout section 35 are sequentially operated based on the ball removing operation. In other words, when the switch 14 for ball removal is operated, the switching discharge unit 47 is switched based on the control processing in the second electronic control unit 22 for this detection input and the command for ball removal, and the electromagnetic solenoid is operated. As the rod 49 rises due to the excitation of 48, the switching valve 5
2 is switched to the return position and held (FIGS. 12 and 13).
reference). Following this (for example, after 1.5 seconds), the ball payout unit 35
Is released, and the restricting piece 41 is magnetically displaced by the excitation of the electromagnetic solenoid 39 to release the ball feeder 37. As a result, the ball stored in the ball storage / discharge path section 4 is illustrated in FIGS. 12 and 13 under the condition that the ball feeder 37 continuously rotates freely while receiving the ball in the ball entrance 28 of the case body 26. As a result, the balls are discharged one by one into the payout path 30, pass through the return path 31 while being deflected and guided by the switching valve 52, and are 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 35 is returned to its original state, the demagnetization of the solenoid 39 causes the regulating piece 41 to return to its displacement, and the ball feeder 37 is stopped and held. Subsequently (for example, after 3.5 seconds), the switching discharge portion 47 is restored to its original state, and the switching valve 52 is held at the original dispensing position (the position shown in FIG. 11B) with the lowering of the rod 49 due to the demagnetization of the solenoid 48. Is done.

In the above-described ball removing 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 solenoids 39 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
The ball entrance 2 of the ball payout section 35
The ball is passed (accommodated) from a predetermined position (the position at which the ball feeder 37 is received) in the ball storage / discharge path 4 so that the above-mentioned rental ball and prize ball can be paid out. Incidentally, the second electronic control unit 22 according to the prize ball discharging device F of the present embodiment.
As another setting example, the ball lending operation signal can be input after the prize ball payout command is completed, and the ball lending operation signal is disabled (invalid) after the ball removal operation signal is input. 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. In addition, the ball-pulling operation signal is set to 1 after the end of the instruction to pay out the lending ball and the prize ball.
Valid input is allowed only once.

By the way, in the prize ball discharging device F of this embodiment,
In addition to being able to perform the above-described ball discharge operation, it is also possible to prevent the illegal acquisition (removal to the upper ball plate side) of stored balls to be discharged outside the machine by a ball removal operation as a unique function of the device, Regarding this preventive measure, it is possible to detect and operate the ball release switch 14 with an operation rod inserted from an operation hole (both not shown) of the front frame B to hold the switching discharge portion 47 in the ball release state. Even if an illegal object is intruded from the supply port 6 to the back side by an illegal operation on the front side of the machine and is skillfully manipulated, the switching valve 52 is protected by the guide prevention piece 55. That is, as a specific defense posture of the guide prevention piece 55, first, as illustrated in FIG. 11B, the guide prevention piece 55 for the switching valve 52 of the dispensing position has a lower half portion thereof from the inside of the dispensing path 30. The exit surface of the payout path 30 is extended to the upper end portion of the first prize ball path 5 and closed. As illustrated in FIG. 13, the lower half of the guide prevention piece 55 for the switching valve 52 at the return position has the lower half portion of the partition wall 2 of the base plate 26A.
9, extends in an arc shape at the upper end of the first prize ball path 5 and substantially closes and blocks the exit surface of the payout path 30. In this state, the intrusion of unauthorized goods into the inside of the vehicle 30 is prevented.

Therefore, in the intrusion prevention state shown in FIG. 11 (b), the linear illegal object 61 is caused to enter the first prize ball path 5 from the supply port 6 and then to the payout path 30 before the illegal ball removing operation.
When the insertion operation is performed on the side, the upper end of the fraudulent object 61 comes into contact with the lower half of the guide preventing piece 55 and is pushed up as shown in FIG. 14, so that the lower half is elastically deformed and the lower end is dispensed. It locks to the exit end of the road 30 to prevent further entry of the unauthorized article 61 while closing the exit surface of the road 30. As a result, even if the switching valve 52 is restrained at the dispensing position as shown in the drawing, the electromagnetic solenoid 48 is operated by the subsequent illegal ball removing operation, so that the switching valve 52 receiving the exciting force causes the unauthorized valve. It overcomes the thrust force of 61 and is forcibly switched and held at the original return position. For this reason, the stored balls discharged from the ball payout section 35 are deflected and guided by the switching valve 52 and flow out to the return path 31, and none of the balls flow out to the payout path 30. In this fraud prevention, the switching valve 52 is constrained to an intermediate position between the dispensing and returning (the position shown in FIGS. 15A and 15B) due to the relationship between the exciting force and the thrusting force. Even so, the discharged storage sphere collides with the upper end of the switching valve 52 and pushes the switching valve 52 to the return position side with the force of its fall to pass through the return path 31.

On the other hand, in the above-described intrusion prevention state shown in FIG. 13, an illegal object 61 previously intruded into the first winning ball path 5 from the supply port 6 was inserted into the payout path 30 after the illegal ball removing operation. In this case, as shown in FIG. 15 (a), the illegal object 61 enters the lower half of the guide prevention piece 55 along the outer circumference of the bell 62 and pushes up, so that the lower half is elastic. It is deformed and its lower end is locked to the exit end of the payout path 30 to close and shut off the exit surface, thereby preventing the intrusion of the illegal article 61.
Thereby, even if the switching valve 52 held at the return position as shown in the figure is slightly displaced against the exciting force of the electromagnetic solenoid 48 in accordance with the deformation of the guide preventing piece 55,
It is not bound at all by the payout position. Therefore, the stored balls already discharged from the ball discharging section 35 in this state are not discharged to the discharging path 30 even if they collide with the upper end of the switching valve 52 as shown in FIG. The valve 52 is pushed open to the return position, and passes through the return path 31. Specifically, even if the unauthorized object 61 is forcibly pushed up, it is pushed back by the elastic force of the guide prevention piece 55,
Also, the switching valve 52 overcomes the thrusting force and returns to the return position by the combined force of the strong falling force of the discharged storage ball and the original exciting force of the electromagnetic solenoid 48.

As another attempt from the above-mentioned unauthorized operation,
For example, an illegal object 61 having a hook portion 61a is used to intrude into the first prize ball path 5 from the supply port 6, and the oblique shape of the first prize ball path 5 is schematically shown in FIG. Payout path 3 along the wall
When the insertion operation is performed on the 0 side, even if the hook 61a of the unauthorized object 61 can enter the outlet of the payout path 30 while pushing down the lower half of the guide prevention piece 55, as shown in FIG. Interferes with the oblique partition wall 29 of the payout path 30, and the linear portion interferes with the lower part of the guide prevention piece 55, so that the movement of the unauthorized object 61 is prevented by the guide prevention piece 55 while preventing further intrusion. Will be limited. Thus, even if the switching valve 52 switched to the return position as shown in the figure is pushed by the hook 61a of the unauthorized object 61 and slightly displaced against the exciting force of the electromagnetic solenoid 48, the switching valve 52 is restrained at the dispensing position. Not done. Therefore, the stored balls released from the ball payout unit 35 are:
The valve 52 collides with the switching valve 52 and is pushed and opened to the original return position side by the dropping force to pass through the return path 31. When the illegal object 61 is pulled out in this illegal state, the switching valve 52 receives the exciting force of the electromagnetic solenoid 48 and is held at the original return position shown in FIG.
