DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball channel switching unit device for a pachinko game machine, and more particularly, to a pachinko ball stored on the back side of a machine as a prize ball for winning a game. A switching unit that can electrically switch the flow path between a prize ball and a return ball in a gaming machine that can be discharged to the plate) side, and can be discharged outside the machine as a return ball (return ball) by a ball removal operation. It concerns the device.

[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. By operating the switching device of the ball flow path of the above, the switching valve provided at the branch connecting portion between the prize ball path and the ball removal path is held in the ball removal state (ball return position), and the stored balls are removed. The ball can be discharged from the ball-extraction path to the outside of the aircraft. The operating rod is a wire-like material with a knob and is managed by the hall manager,
A straight line 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 drive control of the electric ball is used to control the rotation of the ball feeder facing the ball path while paying out the prize ball and detecting the count. In the ball channel switching device, a switch operated by the operation rod is used. The solenoid valve is driven and controlled based on the detection input, and the switching valve is pulled out (returned).
An electric type which is switched to a position and pulled out is used. 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 dispensing device is installed in accordance with the downstream portion of the ball storage / discharge route portion, and a switching device is installed at a branch connection between the prize ball route and the ball pull-out route communicating with the downstream of the prize ball dispensing device. Based on the detection input of the switch in the withdrawal operation, all the withdrawn ball can be discharged under the condition of holding the switching of the switching valve and releasing the prize ball payout device.

[0004] In the switching device, besides the operating rod, a switch operation can be detected 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]

In the above-mentioned conventional ball flow switching device, a linear type having a rectangular outer shell is used as an operating means for rotating the switching valve between a ball discharging position and a ball removing position. An electromagnetic solenoid or a rotary type electromagnetic solenoid having a circular outer body has been implemented. However, in the linear type electromagnetic solenoid, since the rod reciprocates linearly, a linking member for converting the linear displacement of the rod into the rotational displacement of the switching valve is required, and the operating system of the switching valve is required. However, there is a drawback that the apparatus becomes complicated and malfunctions such as malfunctions easily occur, and the whole apparatus becomes large. On the other hand, in the rotary type electromagnetic solenoid, since the switching valve can be directly connected to the rod, the operation system for the switching valve is simple, and there is an advantage that operation failure or the like can be prevented. Due to the large size, the installation area becomes large, and the size of the entire apparatus cannot be reduced accordingly. Therefore, in the mechanism set board, it is necessary to secure a large installation section on the assumption of the outer size of the ball flow switching device, and the design of the entire prize ball discharge path and the like are somewhat restricted and difficult to handle. be pointed out.

[0006] Further, even if the switching device is constituted by a case body in which the electromagnetic solenoid, the switching valve and the like are housed and set in a case body, it is inconvenient to handle because the device itself is large. Screws, screws, and the like have been used for attachment and fixation to the installation portion.
That is, in the conventional switching device, when attaching to the installation portion, it is necessary to tighten the screws and the like with a required tool such as a screwdriver, so that it takes time and effort, and when removing from the installation portion, the screw with the required tool is required. And the like, which requires a work to remove the slack, and therefore, there is a problem that the work and the time are similarly troublesome. In particular, in the disposal processing of the pachinko gaming machine, the disassembly work for each part is complicated and time-consuming due to the difficulty in removing the switching device, so that the disposal processing cost is increased and the recycling is speeded up and rationalized. This was a major obstacle in planning.

[0007]

In the pachinko machine according to the present embodiment configured as described above, the card unit E is provided 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 a ball discharging operation state of the prize ball payout device F implemented in such a pachinko machine and the ball flow switching unit device G of the present embodiment. First of all, about paying out rental balls,
Under the ball presence detection input condition of the ball lending switch 11, the ball payout unit 30 is operated based on the fact that a card is inserted and the ball lending switch 59 is operated. That is, the ball payout section 30 of the prize ball payout apparatus F is operated based on the control processing between the card reader 23, the interface board 24 and the second electronic control device 22 in response to the operation input of the switch 59, and the ball lending command. Control operation (excitation and demagnetization) of the electromagnetic solenoid 34 and the regulating piece 3
6, a predetermined number of balls are detected by the ball presence detection input of the first and second detectors 38 and 39 and the pitch rotation of the ball feeder 32.
(For example, 25 lending balls for 100 yen lending amount) is 1
The balls are paid out one by one, discharged from the ball payout path 43 in the switching unit apparatus G to the first prize ball path 5, and supplied from the supply port 6 to the upper ball plate. 5 and 15 (a) show the specific state of discharge of the lent ball, all the lent balls are released from the receiving portion 33 of the ball feeder 32, and the second detector 3
At 9, the count is detected, the ball enters the ball entry path 40, passes through the ball ejection path 43 along the switching valve 49 held at the upright dispensing position, and is then discharged to the first prize ball path 5. You.

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, in the case of removing the stored balls, the ball switching discharge unit 47 of the ball flow switching unit G and the ball dispensing unit 30 of the prize ball dispensing device F are sequentially operated based on the ball removing operation. . That is, the switch 14 for removing balls is used.
Is operated, the ball switching discharge unit 47 is switched based on the control processing in the second electronic control device 22 and the ball removal command in response to the detection input, and the rotation shaft 54 is excited by the electromagnetic solenoid 48. With the rotation of, the switching valve 49 is switched and held at the tilt return position (see FIGS. 5 and 15B). Subsequently (for example, after 1.5 seconds), the ball dispensing section 30 is opened, and the restricting piece 36 is magnetically displaced by the excitation of the electromagnetic solenoid 34 to release the ball feeder 32. As a result, while the ball feeder 32 continuously rotates freely while receiving the ball in the ball passage 28, the stored ball in the ball storage / discharge path section 4 discharged one by one is switched to the switching valve 49.
The ball passes through the ball return path 44 while being diverted and guided to the outside of the machine from the ball release path 9. 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. Subsequently (for example, after 3.5 seconds), the ball switching discharge portion 47 is restored to its original state, and the rotary shaft 54 becomes free due to the demagnetization of the solenoid 48. Position (the position shown in FIG. 15A).

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 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 according to the prize ball payout device F and the ball channel switching unit device G of the present embodiment, the ball lending operation signal can be input after the prize ball payout command ends. 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.

In the pachinko machine of this embodiment, the prize ball dispensing device F and the ball channel switching unit device are installed on the installation frame in the game hall as described above and are being used for the game. G can be easily and easily removed from the recess 25 by a one-touch operation. That is, the locking member 70 is rotated to the unlock position and the engagement plate 75 is rotated.
In a state where the engagement with the engagement piece 68 is released, the winning ball dispensing device F can be easily removed by pulling the winning ball dispensing device F upward and forward. Further, if the switching unit device G is pulled up in a state where the winning ball dispensing device F has been removed from the concave chamber portion 25, the switching unit device G can be easily removed. Moreover, when the locking member 70 is held at the unlocked position, the movable regulating member 8 in the ball flow regulating device 85
7 is held in the tilt-restricted state, so that, for example, even if a pachinko ball remains in the ball storage / discharge path portion 4,
The pachinko balls do not flow out of the delivery gutter 4c.

Further, in the pachinko machine according to the present embodiment, as described above, the prize ball dispensing device F and the switching unit device G can be removed very easily and easily. This can speed up and rationalize each disassembly operation.

[Modification] FIG. 17 is an exploded perspective view showing a modification of the ball channel switching unit device in the pachinko gaming machine of the present invention, and FIG. 18 shows an operation mode of the switching valve in the switching unit device. It is a vertical side view. In switching unit device G ₁ sphere flow path according to this modification, with respect to the switching unit device G of the sphere flow paths shown in Example, the installation portion 93 formed in the front surface of the cover 41B of the case body 41, infested Switch button 91 of the case body 4
1 is provided with a maintenance switch 90 directed inward, and a pressing piece 92 for pressing the switch button 91 is integrally formed on the side of the switching valve 49. The maintenance switch 90 is held in an OFF state when the switch button 91 is not pressed, and is turned ON only while the switching valve 49 is rotationally displaced to the inclined return position and the pressing piece 92 is pressing the switch button 91. And is connected to the second electronic control unit 22 (see FIG. 16). As described above, by providing the maintenance switch 90 for detecting that the switching valve 49 is positioned at the tilt return position, for example, an illegal operation of the stored ball using an illegal object such as a wire inserted from the front side of the pachinko machine. Extraction can be suitably prevented. An arc-shaped elongated through hole 94 is formed on the side surface of the cover 41B, and an operation rod inserted through the through hole 94 is engaged with an operation hole 95 formed on the side surface of the switching valve 49. The switching valve 49 can be manually rotated.

For example, before the ball discharging operation of the prize ball dispensing device F, the switching valve 49 is held at the upright dispensing position and separated from the switch button 91 (FIG. 18).
(See (a)), the maintenance switch 90 is turned off, and the non-detection condition of the switching valve 49 is input to the second electronic control unit 22. Therefore, the ball dispensing section 30 is controlled to be in a dispensing release inoperable state by the non-detection condition of the maintenance switch 90, and the dispensing electromagnetic solenoid 34 is controlled to be stopped. When the ball removing switch 14 is operated by the operating rod inserted from the front frame B, the switching electromagnetic solenoid 48 in the ball switching discharge section 47 is excited, and the switching valve 49 is rotated by the rotational displacement of the rotating shaft 54. Is switched to the tilt return position and held. At this time, the pressing piece 9 of the switching valve 49
When the user presses the switch button 91 of the security switch 90, the security switch 90 is turned on.

Then, in the state where the stored ball is extracted,
When the illicit object is caused to enter the ball payout path 43 through the supply port 6 and the first prize ball path 5, the tip of the illicit object contacts the switching valve 49, and the switching valve 49 moves to the upright dispensing position. It turns, and the pressing of the switch button 91 by the pressing piece 92 is released. That is, the maintenance switch 90 is turned off.
In the state, the non-detection condition of the switching valve 49 is input to the second electronic control unit 22, so that the dispensing electromagnetic solenoid 34 is demagnetized, and the dispensing of the stored ball is stopped.
Therefore, even if the switching valve 49 can be forcibly rotated and displaced to the upright dispensing position by an improper object, the dispensing electromagnetic solenoid 64 is demagnetized. Only one or two balls located upstream of the payout path 43 can be extracted.

FIG. 19 shows a ball entrance path 40, a ball payout path 43, and a ball return path 4 in the ball flow path switching unit device G.
4 is a modified example in which the switching valve 49 is formed in an inverted Y-shape.
Are disposed so as to be tiltable to the 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. When removing the stored ball, the switching valve 49 is held at the ball return position in which the switching valve 49 is tilted to the left while the rotating shaft 54 is rotated by the excitation of the electromagnetic solenoid 48, and the stored ball is inserted into the ball. From 40, it is guided to the ball return path 44 side.

[0043]

As described above, according to the ball flow switching unit apparatus in the pachinko game machine according to the present invention, the ball payout path communicating with the prize ball discharging path and the ball return path communicating with the 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 switching unit device itself can be reduced, and the handling becomes easy. Furthermore, as the switching unit device becomes smaller and lighter, 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 discharge path and makes it easier to install other equipment. Has a beneficial effect.

Further, a locking portion is formed at a required position of the case body in the switching unit device, and a locking portion which is aligned with the locking portion is formed at a required position of the installation portion. By utilizing the action of engagement with the stop, the switching unit device is configured to be easily and easily attached and detached only by manual operation. As a result, not only can the assembling work of the pachinko machine be simplified and streamlined, but also in the disposal processing of the gaming machine, the disassembly work for each part can be speeded up and streamlined to reduce the cost associated with the disposal processing. There are advantages such as realization.
