Description

[Detailed description of the invention] The present invention relates to a ball launcher for an electric game machine. To explain in more detail, the invention includes a ball launcher that is integrated into the mounting plate, and a ball launcher that is integrated into the front plate. The present invention relates to a ball launcher for an electric game machine that includes an operating handle mechanism.

In conventional electric game machines, when adjusting the batting force of the batting rod that hits balls such as pachinko balls,
This is done using long tension coil springs, etc.
This tension coil spring was set to a predetermined tension and was attached to the bottom of the back surface of the front frame of the gaming machine. For this reason, there was a drawback that a long installation space was required in the lateral direction. Further, in order to adjust the ball striking lever spring by the operating handle mechanism, it is necessary to attach the operating handle mechanism and the ball striking lever spring in association with each other.
The work of assembling these parts is complicated, and the work efficiency cannot be improved.

The purpose of the present invention is to provide a ball launcher for an electric game machine that does not require a long installation space in the horizontal direction and has excellent workability in assembling each part. It will become clearer.

1 and 2 schematically show an embodiment in which the ball launcher for an electric game machine according to the present invention is applied to a pachinko game machine, and this pachinko machine 1 has a front frame 8.

the first transmission link 1 on the front side of the mounting plate 24;
A second transmission link 40 is rotatably supported at a position opposite to the second transmission link 40.
is formed with an uneven portion 40a which protrudes forward and can engage with the uneven portion 16a of the first transmission link 16 during assembly. This rotation of the second transmission link 40 adjusts the coil spring 29 or the ball hitting force adjustment spring 45 that adjusts the ball hitting force of the ball hitting rod 25 .

A batting rod 25 and a batting motor 2 are mounted on the back of the mounting plate 24.
6 is attached to the hole 24a formed in the mounting plate 24.
The rotating shaft of the ball hitting motor 26 protrudes toward the front side of the mounting plate 24, and a driving blade 27 having three blades is fixed to this rotating shaft. In addition, a pair of stoppers are fixed to the back surface of the mounting plate 24, and a pair of stoppers are fixed to the back surface of the mounting plate 24,
It regulates the rotation of. A cylindrical base 33 is attached to the front side of the mounting plate 24, and this cylindrical base 33
A batting shaft 28 to which a batting rod 25 is fixed inside.
is pivotally supported, and an engagement member 30 having an engagement pin 30a is fixed to the front end surface of the ball-striking shaft 28. A ball-striking lever spring 29 made of a coil spring is fitted to the outer periphery of the ball-striking shaft 28, and the ball-striking lever spring 29 is one end of 29 29
a is locked to the engaging member 30, and the other end 29b is locked to an adjustment ring 31 that fits around the outer periphery of the cylindrical base 33. The adjustment ring 31 has a cylindrical base 33
It is engaged with a pivot ring 32 which similarly fits.

As shown in FIG. 8A, one end 41a of a ball hitting force transmission member 41 is locked to the second transmission link 40,
The other end 41b of this hitting force transmitting member 41 is locked to the rotation ring 32. The adjustment pin 34 of the adjustment plate 34 is located in the middle of this hitting force transmission member 41.
A ball-hitting force adjusting roller 42 is pivotally supported by the adjusting pin 34a, and a ball-hitting force transmitting member 41 is hooked onto this roller 42. This adjustment pin 34
a is an arcuate slit 24 formed in the mounting plate 24;
By moving b, the end 41b of the ball-hitting force transmission member 41 is pulled, and the return force of the ball-striking rod spring 29, which is a coil spring, is adjusted and set, and the ball-striking rod 2
A batting force of 5 is set.

Therefore, when the handle ring 13 is rotated clockwise and the first transmission link 16 is rotated, the second transmission link 40 that engages with the handle ring 13 is also rotated in the same direction, and the batting force transmission member is rotated. 41 is pulled, the rotating ring 32 rotates in a direction that provides a return force greater than the return force set for the ball hitting rod spring 29, and the ball hitting force of the ball hitting rod 25 is adjusted.

Further, FIG. 8B shows a different embodiment of the present invention, and parts corresponding to those in FIG. 8A are given the same reference numerals and further detailed explanation thereof is omitted. One end of a return spring 45 is connected to the end 41b of the transmission member 41, and the other end of the return spring 45 is connected to the engagement pin 30 of the engagement member 30.
The embodiment described above except that another linear member 46 is connected to the a side, and another linear member 46 is locked to the rotation ring 32, and the other end of the linear member 46 is locked to the adjustment pin 34a. It has the same configuration as .

Therefore, the position of the adjustment pin 34a is adjusted to set the return force of the ball striking lever spring 29, and the handle ring 13 is adjusted.
When rotated clockwise, the first and second transmission links 16 and 40 rotate in the same direction, and the return spring 45 is pulled via the ball hitting force transmission member 41.
The batting force of the batting rod 25 is adjusted to be greater. In this embodiment, the ball hitting force of the ball hitting rod 25 is adjusted by adjusting the tension of the ball hitting rod spring 29 and the separate return spring 45, so there is no possibility that the vibration of the ball hitting rod spring 29 will be transmitted to the player. Moreover, since only the return spring 45 needs to be adjusted, the adjustment force required by the player can be reduced.

FIG. 11 shows a positioning mechanism for the adjustment plate 34, in which a positioning fixing member 36 having an inward flange 36a is fixed to the back surface of the mounting plate 24, and a positioning rotation member 35 is installed inside the fixing member 36. They are mated. The rotating member 35 is attached to the mounting plate 2
The adjusting plate 34 is rotatable around a pin 48 fixed to the rotating member 35.
is installed. Rotating member 35 and fixed member 3
Engagement portions for regulating clockwise rotation are formed on the outer periphery of the joint surfaces of 6, respectively, and although the rotation member 35 is normally engaged and regulated, the operation knob 38 formed on the outside cannot be used. By pressing, the engaged state can be released, and by rotating this operation knob 38, the adjustment plate 34 is rotated, and the adjustment pin 3 is rotated.
4a pulls the ball hitting force transmitting member 41 or the linear member 46, and the return force of the ball hitting lever spring 29 is adjusted.

Further details of the operating handle mechanism 5 will be explained with reference to FIGS. 9 and 10. The handle ring 1 of the handle body 11 attached to the upper case 10
A touch detector 23 having a flange portion 36a is attached to a position adjacent to the touch detector 3, and a lead wire 51 is attached to this touch detector 23 by a pin 52. This lead wire 51 is connected to a touch switch circuit (not shown), and the ball hitting motor 26 becomes ready to be driven when the player touches the ball. The player rotates the handle ring 13, turns on the rotation detection switch 20, selects the desired hitting force, and then touches the touch detector 23.
The hitting of the pachinko ball starts, and unnecessary hitting can be prevented.

The above is an outline of one embodiment of the ball launcher for an electric game machine according to the present invention. According to such a configuration, there is a handle ring rotatably attached to the handle body, and A first transmission link that rotates when rotated, an operation handle mechanism formed by integrating them into a front plate, and a second transmission link that is connected to a ball hitting lever spring via a ball hitting force transmission member. a ball firing mechanism formed integrally on a mounting plate, the operating handle mechanism is provided with a coupling member, the mounting plate is provided with an insertion hole,
