As shown in FIG. 1, an opening 43a for connecting a lead wire is formed in the lid 43, and fittings for inserting and supporting both ends of the drive control board 40 are formed in the middle portions of the inner surfaces of both side walls 43b. The support portion 44 having the mating groove 44a is projected. Then, as shown by a two-dot chain line in FIG.
While the drive control board 40 is supported on the
After contacting with 42, it is fixed by screw 45,
The drive control board 40 is mounted. As shown in FIG. 5, a limit switch 46 for driving the electric motor is attached to the main set plate 3 at a position corresponding to the pressing piece 33a at the upper end of the drive lever 33. The pressing pieces 33a at the upper end of the 33 are turned on and off when they come apart and come into contact with each other.
As shown in FIG. 10, after the limit switch 46 is inserted into the accommodating portion 47 formed on the back side of the main set plate 3, an elastic locking hook formed on the front side of the set plate 3 is provided. According to 48, it is attached without using screws or the like. As shown in FIG. 5, a single-use limit switch 49 is provided on one side of the main set plate 3, and by pressing a push button (not shown) provided on the front surface of the operation panel, the The electric motor 37 can be driven intermittently.

With this wiring processing unit, lead wires (not shown) connected to the limit switch 46, the single-use limit switch 49, and the like are collectively guided. Thereby, the wiring process of the lead wire related to the launching device becomes very easy. The lead wire can be led out from the front side to the back side and from the back side to the front side of the ball launcher assembly 1 by the notch 55, and the lead wire can be attached to the ball launcher assembly 1 by the notch 55. Since the lead wire is housed in the wiring guide portion 54 and the notch 55, the lead wire does not hinder the assembly of the launching device. The ball launcher assembly 1 configured as described above is fixed to the back of the operation panel of the pachinko machine main body as described above,
As shown in FIGS. 1 and 2, a rotation shaft 50a of an operation handle 50 attached to the surface of the operation panel is
It is inserted so as to be able to rotate integrally with 1. This connecting shaft 31
A touch switch (not shown) is built in, and when the player is touching the operation handle 50, the touch switch operates to drive the electric motor 37. Next, the hitting action of the electric pachinko machine configured as described above will be described. When the operation handle 50 is rotated, the operation handle connecting shaft 31 is rotated, and the touch switch inside the operation handle is operated. At this time, the rotation of the operation handle connecting shaft 31 causes
The cam plate 32 presses the cam roller 35 of the drive lever 33, and the drive lever 33 is tilted counterclockwise as shown by a two-dot chain line in FIG. The tilt of the drive lever 33 is transmitted to the driven lever 27 via the connecting link 36, and the driven lever 27 is opposed to the biasing force of the tension coil spring 21 by a two-dot chain line from the position shown by the solid line in FIG. Is tilted clockwise toward the position indicated by. Then, when the operation handle 50 is stopped at an arbitrary rotation operation position, the driven lever 27 is positioned, and the switch locking portion 19 of the sliding body 17 is held at a fixed position. Further, due to the tilting of the drive lever 33, the pressing piece 33a at the upper end thereof is separated from the limit switch 46, and the electric motor 37 is driven. When the output shaft 37a of the electric motor 37 rotates, the cam plate 38 presses the cam roller 39 of the hitting rod 4,
The striking rod 4 tilts against the urging force of the tension coil spring 21 that is stretched from the switch locking portion 19. The ball feed member (not shown) is operated by the tilting of the hitting rod 4, and the ball of the ball discharge port 8 flows in. When the cam plate 38 of the output shaft 37a of the electric motor 37 separates from the cam roller 39 of the hitting rod 4, the hitting rod 4 is moved to the position indicated by the solid line in FIGS. The ball of the ball discharge port 8 is fired by the resilient portion 4a. If the operation handle 50 is kept at a constant rotational operation position, the driven lever 27 is always at a constant position.
The spring locking portion 19 of the sliding body 17 is also held at a fixed position,
The elastic coil spring 21 is always stretched by the same dimension, so that the hitting rod 4 can repeatedly hit the ball with the same elastic force. When the rotation amount of the operation handle 50 is changed, the holding position of the driven lever 27 changes, so that the holding position of the spring locking portion 19 of the sliding body 17 also changes. Accordingly, the amount of extension of the elastic coil spring 21 is increased or decreased, and the elasticity of the striking rod 4 can be changed. Also, as shown in FIG.
22a is bent, and the locking projection 24 is pulled out from the locking hole 25 which was in the engaged state.
Is rotated from the position shown by the solid line in FIG. 1 to the position shown by the solid line in FIG. 2, the driven lever 27 is moved in the horizontal direction. At this time, since the lower end of the driven lever 27 is connected to the drive lever 33 by the connection link 36, the driven lever 27 is rotated clockwise about the shaft 26. With the movement of the driven lever 27 in the horizontal direction and the clockwise rotation, the sliding body 17 moves in the direction away from the hitting rod 4 along the guide hole 18 and the holding position of the spring locking portion 19 is also changed. Change. Therefore, the elastic coil spring 21 is extended, and the elastic force of the striking rod 4 increases. Now, in this embodiment, a housing 41 is formed on the motor set plate 3a, and the electric motor 37 is provided in the housing 41.
Since the drive control board 40 is assembled, failure of the drive control board 40 due to contact with other components can be prevented. In this embodiment, the base 42 and the cover 43 are attached to the motor set plate 3a.
The housing 41 is formed, and the lid 43 is provided with a support portion 44 having a fitting groove 44a for inserting and supporting both ends of the drive control board 40, so that the drive control board 40 can be easily and easily provided. It can be securely mounted on the motor set plate 3a. In the present embodiment, first, the hitting rod 4, the sliding member 17, the tension coil spring 21 for firing, the operating handle connecting shaft 31, the drive lever 33, the connecting link 36, the elastic force adjustment of the ball firing device 2 are set. The lever 22 and the like are integrally attached to the main set plate 3 and the electric motor of the device 2 is attached to the motor set plate 3a.
37 and the like are integrally assembled to form the ball launcher assembly 1,
The ball launcher assembly 1 can be fixed to the back of the operation panel of the pachinko machine main body. Therefore, it can be used in terms of mounting space, mounting procedure, and the like because of the relationship with other components to be mounted on the pachinko machine main body, and the efficiency of assembly work can be improved. Effect of the Invention As described in detail above, according to the present invention, the circuit board for driving the electric drive source of the ball launching device is attached to the main body of the ball launching device and is unitized.
