And a microswitch 12 that emits a signal when an actuator piece 12a is engaged with the recessed portion 11. On the other hand, a switch button 13 for starting the deceleration motor 8 of the electric ball removing means 6 is provided on the front surface of the upper bowl 1.

[0008] The lower ball tray 2 is fixed to the front lower edge of the front frame 14 of the pachinko machine P, and a ball outlet 1 opened in the front frame 14.
Pachinko balls flow in through 5. Although not shown, the prize ball discharge gutter of the mechanism plate and the ball removing passage 3 join at a position before reaching the ball outlet 15. As shown in FIGS. 5 and 6, the ball punching member U of the lower ball tray 2 horizontally extends along a ball hole 16 formed in the bottom wall 2 a of the lower ball tray 2 and the lower surface of the bottom wall 2 a of the lower ball tray 2. A shutter plate 17 that reciprocates in the direction to open and close the hole 16, a fixed frame 18 that slidably supports the shutter plate 17, and a shutter plate 17 that is located between the fixed frame 18 and the shutter plate 17. It comprises a spring 19 that urges in the closing direction, and an operation lever 20 that protrudes integrally with the shutter plate 17. The ball removing member U of the lower bowl 2 is provided with a hole removing detection means 23 which is formed by a combination of a reed switch 21 fixed to the fixed frame 18 and a magnet 22 fixed to the shutter plate 17. . The reed switch 21 and the magnet 22 are set such that the reed switch 21 is turned on when the shutter plate 17 is moved to the open position. On the other hand, the launch operation detecting means 24 for detecting that the player is performing a launch operation uses an existing touch switch 26 provided on a hitting handle 25 for adjusting the launching power of the pachinko ball.

The reed switch 21 of the ball-hole opening detection means 23 and the touch switch 26 of the firing operation detection means 24 are connected to a control device 27 fixed to a mechanism plate.
Is electrically connected to On the other hand, the control device 27
Is programmed to operate the electric ball removing means 6 on condition that the release signal of the reed switch 21 is ON and the firing signal of the touch switch 26 is OFF.

Next, the operation of the ball removing device of the present invention will be described. In a normal game state, the distal end of the valve plate 5 closes the entrance of the ball emptying passage 3 as shown in FIG.
Pachinko balls flow to the automatic ball feeder. In this state, when the player consciously flows the pachinko ball of the upper ball dish 1 to the lower ball dish 2, the switch button 13 of the upper ball dish 1 is pushed once. Then, upon receiving the signal, the deceleration motor 8 of the electric ball removing means 6 starts. By the operation of the deceleration motor 8, the roller 10 of the rotary plate 9 pushes the hanging arm 5a to slide the valve plate 5 sideways. When the rotating plate 9 rotates 90 degrees, the actuator piece 12a engages with the recess 11 of the rotating plate 9 to generate a signal as shown in FIG. 3, and the signal causes the deceleration motor 8 to stop. In this state, since the valve plate 5 opens the entrance of the ball removing passage 3, the pachinko balls of the upper ball tray 1 flow to the lower ball tray 2 through the ball removing route of the ball removing passage 3. When the switch button 13 is further pushed one time, the rotation plate 9 is again rotated by 90 degrees by the operation of the deceleration motor 8, and the valve plate 5 returns to the closed position of FIG. Close. On the other hand, when putting the pachinko ball of the lower ball tray 2 into the ball box during the continuation of the game, after placing the ball box below the ball punching hole 16 of the lower ball tray 2, the shutter plate is placed as shown by the chain line in FIG. The operation lever 20 of 17 is slid sideways to open the hole 16 and the state is held by hand. Then, when the operator releases the operation lever 20 at an appropriate time, the elasticity of the spring 19 causes the shutter plate 17 to return, and the ball hole 16 is closed. The shutter plate 17
6 is moved to the open position as shown by the chain line in FIG. 6, the reed switch 21 of the firing operation detecting means 24 is turned on, but since the game is continuing and the touch switch 26 is turned on, the electric ball of the upper ball plate 1 is turned on. The extracting means 6 does not operate.

Next, the game is finished, and the upper ball plate 1 and the lower ball plate 2
When transferring all the pachinko balls to the ball box, first release the hand from the hitting handle 25 and move the shutter plate 17 of the lower ball tray 2 to the open position by hand. Then, the ball hole 16 of the lower ball dish 2 is opened, and the pachinko balls in the lower ball dish 2 flow into the ball box. On the other hand, when the shutter plate 17 moves to the open position, the reed switch 21 is operated, and the opening signal of the ball hole opening detection means 23 is turned ON. Also,
Since the player has released his / her hand from the hitting handle 25 as described above, the touch switch 26 is turned off, and the firing signal of the firing operation detecting means 24 is OFF. Therefore, since the condition for operating the electric ball removing means 6 is satisfied, the rotating plate 9 rotates 90 degrees in the above-described manner, and opens the ball removing passage 3 of the upper bowl 1. As a result, the pachinko balls of the upper ball tray 1 flow to the lower ball tray 2 through the ball draining route, and flow out of the ball punching holes 16 together with the pachinko balls of the lower ball tray 2. After confirming that all the pachinko balls on the upper and lower ball dishes 1 and 2 have been lost, the player releases his / her hand from the operation lever 20 of the shutter plate 17. Then, the shutter plate 17 is moved back by the elasticity of the spring 19, and the ball hole 16 is removed.
Close. On the other hand, since the reed switch 21 is turned off by moving the shutter plate 17 to the closed position,
In response to the signal, the rotating plate 9 of the electric ball removing means 6 rotates 90 degrees, the valve plate 5 moves back, and the entrance of the ball removing passage 3 of the upper ball tray 1 is closed.

Although the embodiments have been described above, the present invention is of course not limited to the above embodiments. For example, a solenoid other than the deceleration motor 8 can be used as the electric driving means of the electric ball removing means 6.
Further, although the open-hole detecting means 23 of the embodiment is constituted by a combination of the reed switch 21 and the magnet 22, any type of sensor such as a micro switch or an optical sensor may be used. Further, in the embodiment, the valve plate 5 is reciprocated by the action of the deceleration motor 8 and the spring 7, but an operation lever similar to the shutter plate 17 is integrally provided on the valve plate 5 so as to be protruded as in the related art. It is good also as a structure which can operate the valve plate 5 also manually. In the embodiment, the one push of the switch button 13 or the reed switch 2
The rotation plate 9 is rotated by a signal at which 1 switches from ON to OFF, and the valve plate 5 is set to be moved to the closed position. However, a timer circuit may be combined with this. That is, if the valve plate 5 is not closed even after a predetermined time has passed since the valve plate 5 was opened, the deceleration motor 8 is automatically operated to close the valve plate 5.
By doing so, even if the player forgets to close the valve plate 5,
The valve plate 5 is closed before the next player starts the game. Since the open / close state of the valve plate 5 can be determined by counting the pulses of the microswitch 12 for stopping the deceleration motor 8, the timer may be started using the pulses. Further, in the embodiment, the touch switch 26 of the hit ball handle 25 is used as the firing operation detecting means 24, but the micro switch is turned ON / OFF by the rotation of the hit ball handle 25, or the pachinko ball hit from the firing rail is directly detected. Alternatively, it may be confirmed during the firing operation.

The ball removing member of the lower bowl 2 is, for example,
As shown in FIG. 7, a pin 30 of a rotary arm 29 is engaged with a long hole 28 of the shutter plate 17, and the rotary arm 29 is rotated by a motor 33 via a worm gear 31 and a wheel gear 32. The shutter plate 17 may be started and operated by operating the push button 34 and stopped by the signal of the micro switch 35, so that the shutter plate 17 may be reciprocated electrically. Then, the operation lever is integrally provided on the valve plate 5 without providing the switch button 13 for operating the game player provided on the upper bowl 1, and the ball is removed from the bowl 1 during the game. Is manually operated using the operation lever, and the ball is removed from the lower ball tray 2 by one push of the push button 34. On the other hand, when removing the ball after the game is over, the shutter plate 17 and the valve plate 5 are set to be simultaneously opened by a one-push operation of the push button 34 of the lower ball tray 2. In this case, the even or odd number of pulses of the microswitch 35 may be determined to generate an open signal of the hole opening detection means. In this manner, if the ball-pulling member U of the lower ball tray 2 is provided with the open position holding function, the burden on the player in the ball-pulling operation is further reduced.

[0014]

As described above, the ball punching device of the present invention can perform the ball punching operation of the lower ball tray and the upper ball tray independently during the firing operation as before, and can perform the lowering after the game is over. Since the upper ball tray is automatically removed in conjunction with the ball tray removal operation, there is an effect that the ball removal operation of the pachinko ball can be easily performed with one hand.
