Is rotatably supported between the cylindrical handle support 39 and the palm rest 40, and when the rotary operation is performed around the handle axis in the front-rear direction, the spring pressure of the tension spring 21 is increased via the handle axis. It can be adjusted arbitrarily.

The handle support 39 is fixed to the mounting plate 30, and the palm rest 40 is fixed to the handle support 39. The palm rest 40 is for placing the palm against the player when operating the operation handle 24.
A touch switch 41 near the operation handle 24
Touch piece 42 is provided in a ring shape.

When the player grasps the operation handle 24 by hand to operate the operation handle 24, the touch switch 41
A part of the hand contacts the touch piece 42 to detect the player's hand.

The ball detecting switch 27, the detecting switch 37 and the touch switch 41 are connected to a control means 43 as shown in FIG. The control unit 43 includes a start / stop control unit 44 and a counting control unit 45. When the ball detection switch 27 detects that the ball at the firing position A has run out while the touch switch 41 is detecting the player's hand, the counting control unit 45 starts hitting the ball with the signal of the detection switch 37 from that point. The number of operations of 20 is counted, and when a predetermined number of operations is reached, the start / stop control unit 44
To output a signal.

The start / stop controller 44 activates the firing motor 22 when the touch switch 41 detects the player's hand, and when the player releases the operation handle 24 and the touch switch 41 has finished starting. Alternatively, when the detection switch 37 detects the permanent magnet 36 when there is a signal from the counting control unit 45, the firing motor 22 is stopped.

In the pachinko machine having the above-described configuration, when a pachinko game is played, after the game ball B is put in the upper plate 11 and the operating handle 24 is operated, the firing device 9 is activated and the firing position of the firing rail 19 is fired. The game balls B on A are fired one by one to the upper side of the game board 7 along the guide rails.

That is, when the player grips and turns the operation handle 24 with his / her hand, the spring pressure of the tension spring 21 changes substantially in proportion to the operation amount. On the other hand, when the player's hand comes into contact with the touch piece 42 when gripping the operation handle 24, the touch switch 41 is operated, and the start / stop control unit of the control unit 43 is activated.
A start command is input to the firing motor 22 from 44, and the firing motor 22 starts.

Before the firing motor 22 is started, the cam body 23 is stopped at the stop position C in FIG.
When the cam 22 is actuated, the cam 23 fixed to the rotating shaft 33 is moved as shown in FIG.
Of the hammer 20 and presses the cam roller 35 of the hammer 20, so that the hammer 20 rotates in the direction of the arrow b around the support shaft 31 against the tension spring 21. Then, when the cam body 23 comes off from the cam roller 35, the hammer 20 is rotated around the support shaft 31 in the direction indicated by the arrow b by the tension spring 21 to move from the ball supply device 12 to the firing position A of the firing rail 19. A certain game ball B is hit against the outer guide rail 13 and fired.

Hereinafter, as long as the player operates the operating handle 24 while the touch switch 41 is operated, the firing motor 22 operates, so that the ball supply device 12 sends the shooting rail 19
The game balls B supplied one by one are sequentially fired on the firing position A of the game. Each time the hammer 20 hits and fires the game ball B at the firing position A, the game ball B at the firing position A disappears. Since the game ball B is supplied, the ball detection switch 27 does not operate at that time interval.

During the operation of the touch switch 41 with the player holding the operation handle 24, all the game balls B in the upper plate 11 are exhausted, and the game balls B on the firing position A of the firing rail 19 are cut off. Then, the ball detection switch 27 detects that the ball has run out, and the counting control unit 45 of the control means 43 starts counting the signal from the detection switch 37.

That is, the operation of the firing motor 22 causes the cam 23
Each time the hammer 20 is driven by rotation, the detection switch 37 is operated by the permanent magnet 36 of the cam body 23, and the signal thereof is sent to the count control unit 45.
Count the signal from 37. When the count value reaches the predetermined number of times of operation, the start / stop control unit 44 operates according to a signal from the count control unit 45, and issues a stop command to the firing motor 22 when the cam body 23 reaches the stop position C, The firing motor 22 is automatically stopped.

For this reason, if the game ball B at the firing position A disappears even though the player is operating the operating handle 24, the firing device 9 can be automatically stopped thereafter, so that the firing can be performed. It is possible to prevent unnecessary consumption of electric power of the motor 22, prevent wear of each part of the firing device 9, and improve the durability of the firing device 9 itself.

When the firing motor 22 is stopped, the number of operations of the hammer 20 is configured to be counted by the counting control unit 45. When the count value of the counting control unit 45 reaches a predetermined number of operations, the start and stop is stopped. Since the stop command is issued from the control unit 44 to stop the firing motor 22, the firing motor 22 can be reliably stopped after the hammer 20 has been operated a predetermined number of times.

Regardless of the presence or absence of the game ball B at the launch position A,
When the player releases his / her hand from the operation handle 24 during the game, the operation handle 24 returns around the handle axis, the touch switch 41 stops operating, and the control means 43 receives a signal. Then, when the cam body 23 reaches the stop position C, the detection switch 3
When the sensor 7 detects the permanent magnet 36 of the cam body 23, the signal from the detection switch 37 causes the start / stop control
44 issues a stop command to the firing motor 22 to stop the firing motor 22.

For this reason, when the firing motor 22 stops, the cam body 23 always moves to the predetermined stop position where it comes off the hammer 20.
Thus, the cam 23 does not come into contact with the cam roller 35 and stop in a balanced state. Then, when restarting the game, or when the next player starts the game, the cam body 23 starts to rotate from the stop position C.
The hammer 20 is driven in contact with the cam roller 35.

Therefore, it is possible to reliably prevent the extension of the tension spring 21 which occurs when the cam body 23 comes into contact with the cam roller 35 and stops in a balanced state, and a change in the spring pressure of the tension spring 21 accompanying this. It is possible to play the game under the conditions.

FIG. 5 illustrates a second embodiment of the present invention, in which a timer unit 46 is provided in the control means 43. Timer section
Reference numeral 46 indicates that when the ball detection switch 27 detects that the ball has run out while the touch switch 41 is operating, the timer 46 starts a timing operation, and sends a signal to the start / stop control unit 44 when a predetermined time has elapsed. The start / stop control unit 44 activates the firing motor 22 when the touch switch 41 detects the player's hand, and when the player releases the hand from the operation handle 24 and the touch switch 41 stops operating, or a timer. When the detection switch 37 detects the permanent magnet 36 when there is a signal from the unit 46, the firing motor 22 is stopped.

In this embodiment, the player operates the operating handle 24
If the ball detection switch 27 detects that the ball at the firing position A has run out during the operation of, the timer unit 46 starts the time counting operation from that point in time. Send a signal to Then, the start / stop control unit 44
Issues a stop command to the firing motor 22 to stop the firing motor 22 so that the cam body 23 stops at the stop position C.

Therefore, even if the player is operating the operating handle 24, if the ball at the firing position A runs out, the firing motor 22 can be automatically stopped a predetermined time after that. Further, since the firing motor 22 is stopped after the elapse of a predetermined time by using the timer section 46, the configuration can be simplified.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments. For example, the detection switch 37 is connected to the permanent magnet 36 of the cam body 23.
Although the operation of the hammer 20 is detected through the interface, the permanent magnet 36 may be provided on the hammer 20 and the permanent magnet 36 may be directly detected.

In place of the touch switch 41, a switch for detecting the end of the operation of the operation handle 24, for example, a switch for detecting the return of the operation handle 24 may be provided.
Further, it goes without saying that the present invention can be similarly applied to an arrangement ball machine and other various ball game machines in addition to the pachinko machine of the embodiment.
