Embodiment A Embodiment A of the present invention will be described below with reference to FIGS. 1 is an exploded perspective view showing a ball removing device, FIG. 2 is a sectional view showing a state where a shutter plate is in a closed position, FIG. 3 is a sectional view showing a state where a shutter plate is in an open position, and FIG. FIG. 5 is a front view of the pachinko machine. Pachinko machine P as shown in FIG.
In the figure, a glass door frame 3 and a front plate 4 are provided in a window hole 2 of a front frame 1 so as to be freely opened and closed. An upper ball tray 5 for receiving a premium ball (pachinko ball) is fixed to the front plate 4. On the other hand, a firing handle 6 for adjusting the firing force of the pachinko ball, a lower ball tray 7, and the like are fixed to a lower portion of the front frame 1. The lower ball tray 7 has a ball outlet 9 of a prize ball discharge gutter 8 of a mechanism plate as shown in FIG.
Are opened, and a premium ball overflowing from the upper bowl 5 flows in. A ball hole 11 is opened in the bottom wall 10 of the lower ball dish 7.

The ball removing device 12 comprises a fixed support frame 13, a shutter plate 14, a solenoid 15, a swinging rod 16, and a prize ball remaining amount sensor 17. The fixed support frame 13 is fixedly screwed to the bottom surface of the lower ball tray 7. A shutter plate 14 is slidably fitted between the fixed support frame 13 and the lower ball tray 7. Shutter plate 14
Is a closed position for closing the ball hole 11 of the lower ball dish 7 (FIG. 2).
The moving range is set between the open position (FIG. 3) where the ball hole 11 is opened and the manual operation is performed by using an operation lever 18 integrated with the shutter plate 14. The shutter plate 14
Does not have a power means such as a conventional coil spring, and thus continuously stops at both the open position and the closed position unless an external force is applied. In addition, the shutter plate 1
In order to ensure the stop state of the shutter 4, the shutter plate 14
A structure is adopted in which a magnetic body 19 is inserted on one side of the base member and the magnetic body 19 is attracted to a permanent magnet 20 fixed to the fixed support frame 13. The outer periphery of the permanent magnet 20 is
Because it is surrounded by 1 (magnetic material) and shields unnecessary magnetism,
Pachinko balls are not unnecessarily adsorbed.

The solenoid 15 is fixed to the lower surface of the fixed support frame 13, and has a tip of a plunger 15a pivotally mounted on a swinging rod 16 having one end pivotally connected to the fixed support frame 13. The tip of the swinging rod 16 is in the same horizontal plane as the roller 22 suspended from the shutter plate 14, and the side surface of the swinging rod 16 contacts the roller 22. The solenoid 15
Is electrically connected to a control device (not shown) installed on the mechanism plate. On the other hand, as shown in FIG. 4, the prize ball remaining amount sensor 17 is provided at the ball outlet 9 of the prize ball discharge gutter 8 and has a pressure receiving plate 17a pivotally connected at one end to be swingable.
And a micro switch 17b that generates a pulse signal in response to the swing of the pressure receiving plate 17a. When the prize ball discharge gutter 8 is filled with the prize ball, the remaining amount sensor 17 turns from OFF to ON in response to the ball weight, and changes from ON to OFF when the prize ball in the prize ball discharge gutter 8 decreases. The pulse signal is sent to the control device, and a program is performed so that a ball-pulling end signal is issued approximately 30 seconds after the remaining amount sensor 17 is turned off. In the embodiment A, the closing operation driving means D for forcibly moving the shutter plate 14 to the closed position is a combination of the solenoid 15 and the swinging rod 16. The closing operation control means S for operating the closing operation driving means D is composed of a prize ball remaining amount sensor 17 and a program of a control device.

Next, the operation of the ball removing device 12 of the embodiment A will be described. In a normal state, as shown in FIG. 2, the shutter plate 14 is in the closed position and the ball hole 11 is closed. When a prize ball overflows from the upper ball tray 5 in this state, it flows to the lower ball tray 7 and fills the prize ball discharge gutter 8. Then, the micro switch 17b of the remaining amount sensor 17 is turned ON. To remove the prize ball from the lower ball tray 7 in this state, the operation lever 18 of the shutter plate 14 is moved laterally with a finger. Then, the shutter plate 14 slides to the open position as shown in FIG. 3, the ball hole 11 is opened, and the prize ball flows out. Further, the swinging rod 16 is pushed by the roller 22 simultaneously with the movement of the shutter plate 14, whereby the plunger 15 a of the solenoid 15 is pushed back to the coil portion of the solenoid 15. Since the shutter plate 14 that has moved to the open position has no force applied from anywhere, it stops at that position even if the player releases his hand, and the prize ball continues to flow. Here, when the player stops stopping the ball, the operation lever 18 may be manually moved to the original position.

If the shutter plate 14 is stopped at the open position for a long time and left as it is, the prize ball is continuously discharged, so that the prize ball disappears from the pressure receiving plate 17a of the remaining amount sensor 17 first. . Then, the pressure receiving plate 17a swings upward, and the micro switch 17b is turned off. The control device that has received the pulse signal estimates that the ball removal has been completed 30 seconds after that, issues a ball removal end signal, and excites the solenoid 15 for a predetermined time. As a result, the plunger 15a pops out and the swinging rod 16 swings.
The swinging rod 16 pushes the roller 22 of the shutter plate 14 to forcibly move the shutter plate 14 to the closed position. Then, the solenoid 15 is demagnetized after a predetermined time has elapsed.

The closing operation control means S described above emits a ball removal end signal by a combination of the remaining amount sensor 17 and a timer circuit in the control device. Although the setting is to operate, it is also possible to set to operate the closing operation control means S by a change signal of the player. In the first method, a pachinko ball detection switch 23 is provided on the upper bowl 5 as shown in FIG. 5, and a ball presence / absence signal of the detection switch 23 is used. When the ball-less signal of the detection switch 23 is changed to the ball-present signal, it is determined that the player is to be replaced, and the player's replacement signal is issued. In this method, even if the upper ball plate 5 is once emptied and a new pachinko ball is refilled, a change signal of the player is issued, so that the change information of the player is slightly inaccurate, Solenoid 15 with wrong alternation signal
Is excited, there is no problem if the shutter plate 14 is in the closed position because no change occurs. The second method utilizes a touch switch on the firing handle 6. The signal that the touch switch changes from OFF to ON is determined to be a change of the player, and a change signal of the player is issued. Also in this method, the replacement information of the player is inaccurate, but even so, there is no disadvantage as in the first method.

Next, the operation of the ball removing device 12 of the embodiment C will be described. In a normal state, as shown in FIG. 9, the shutter plate 14 is in the closed position and the ball hole 11 is closed. When the push button 38 is pressed in this state, the motor 29 operates, the wheel gear 31 rotates, and the rotary arm 35 rotates. When the rotating arm 35 rotates, the pin 36
The shutter plate 14 moves toward the open position by the engagement between the shutter plate 14 and the long hole 37. When the rotary arm 35 rotates 180 degrees and reaches the position where the shutter plate 14 is fully opened, the actuator piece 3 of the microswitch 34 is formed in the notch 32 of the disk 33.

Then, a signal is issued from the micro switch 26 of the push button 38, the motor 29 is operated, the rotary arm 35 rotates half a turn, and the shutter plate 14 closes.

Thus, when the prize balls are continuously discharged,
As in the embodiment A, first, the micro switch 17b of the remaining amount sensor 17 is turned off. The control device that has received the pulse signal determines that the ball removal has been completed after 30 seconds have elapsed, and issues a ball removal end signal. On the other hand, the controller can determine the open / close position of the shutter plate 14 by counting the pulses of the micro switch 34 for stopping the motor 29. The motor 29 is rotated only when the issued conditions are simultaneously satisfied, and the shutter plate 14 is automatically closed. In addition, the motor 29 is operated in the above case, and the three conditions of the ball absence signal of the remaining amount sensor 17, the opening signal of the shutter plate 14, and the change signal of the player described in the embodiment A are satisfied. In such a case, it is preferable that the setting is made to operate. Then, even if the shutter plate 14 is kept open due to an erroneous operation of the push button 38 or the like, the shutter plate 14 is always closed when the next game is started.

Although the embodiments A to C have been described above, the present invention is of course not limited to the above embodiments. For example, the shutter plate 14 is urged toward the closed position using a coil spring in the same manner as a conventional ball punching device, and an operation lever also serving as an engagement claw is attached to the shutter plate, and the operation lever is lowered. The shutter plate is stopped at the open position by engaging with the fixed portion of the ball tray (see FIGS. 8 and 9 of Japanese Patent Application No. 3-64601). In addition to manually disengaging the operation lever, It may be electrically disconnected by a combination of a solenoid and a lever. In this case, the closing operation drive unit is a coil spring that urges the shutter plate in the closing direction, and the closing operation control unit is a solenoid that disengages the operation lever, the remaining amount sensor 17, and the like. Further, the closing operation control means S starts the timer circuit from the time when the shutter plate 14 is set to the open position, and performs a predetermined time (based on the time required from the state where the prize ball is most filled to the time when the ball is completely removed). After the determination), a ball-pulling end signal may be issued. In Example B,
In C, the closing operation driving means D may be operated by using the player's change signal as described in the embodiment A.
