Description

[Detailed Description of the Invention] This invention relates to a ball launcher for a pachinko machine in which a drive source is activated to launch a ball when a part of the human body comes into contact with the device.

As is well known, the stray capacitance of the human body is utilized, and when the human body touches or approaches the machine, a low voltage due to the stray capacitance activates a drive source via a switch mechanism, and the drive source activates the firing rod to play pachinko. A ball ejecting device for a pachinko machine that allows this is already known, for example, from Japanese Utility Model Publication No. 8835/1983. In the conventional ball launcher of this type, a rotating part extending to the back side of the pachinko machine is integrally provided in the rotating body of the operation part, and a brush or a contact piece is brought into contact with the rotating part to rotate the low voltage transmitted from the rotating body. This information is communicated from the department to the brushes. However, with this structure, the brushes and other parts are fixed and in contact with the rotating parts, resulting in poor contact, or after long-term use, poor contact between the rotating parts and the brushes may occur, causing the human body to touch the rotating parts. There are also cases where the drive source does not operate and the game cannot be played. In particular, since the low voltage generated by the human body is weak, even the slightest contact failure makes it impossible to operate the drive source.

In addition, in the touch-type batted ball firing device described in Japanese Utility Model Publication No. 56-25710, the lead wire gets twisted when the player rotates the handle, so if the player uses it for a long time, the core wire in the lead wire will break midway. cause trouble.

The present invention has been proposed in view of the above, and will be described below based on embodiments shown in the drawings.

A ball firing operation unit 1 attached to the surface of a pachinko machine consists of a disc-shaped rotating body 2 with a cylindrical part 2' in the center, an outer frame 3 and an inner frame 4 that clamp and support the rotating body 2 from the front and back. It's summery. Outer frame 3 and inner frame 4
has a shallow dish-like shape that opens toward the rotating body 2, and has a cylindrical attachment part 5 on the rear surface of the inner frame 4, which is attached to the front frame a of the pachinko machine, and extends laterally through the center of the attachment part 5. A metal support shaft 6 that protrudes forward is fixedly provided. Then, the cylindrical portion 2' of the rotating body 2 is passed through the support shaft 6, and the outer frame 3 is attached to the tip of the support shaft 6.
Attach. Therefore, the rotating body 2 can rotate around the support shaft 6, and if the rotating body 2 is made of metal, when a human body touches or approaches the rotating body 2, a low voltage due to the human body is generated. A support shaft 6 that is in sliding contact with the inner circumferential surface of the cylindrical portion 2' of the rotating body 2
It will be transmitted to the outer peripheral surface of. The base end 6' of the support shaft 6 is shaped like a cap nut, for example, and the tip of the shaft 7, which is passed through the front frame a from the back, is screwed onto the base end 6'.
The support shaft 6 and the shaft 7 are electrically connected to each other, and the shaft 7 fixes the inner frame 4 to the front frame a. A washer 8 is attached to the head of the shaft 7, and a lead wire is connected to the washer 8. Therefore, the low voltage generated in the rotating body 2 is transmitted from the support shaft 6 to the shaft 7, and from the washer 8 to the lead wire 9, so the lead wire can be connected to a switch mechanism incorporated in the drive source circuit. . Several screw seats 10 are provided protruding from the inner surface of the outer frame 3 described above. This screw seat 10 passes through an arcuate groove 11 bored in the outer peripheral portion of the rotating body 2 and comes into contact with the inner surface of the inner frame 4.
It is fixed by 2. Therefore, the rotating body 2 is rotatably supported within the arcuate groove 11. A rotary shaft 13 is provided in parallel with the support shaft 6 and extends through the mounting portion 5 of the inner frame 4 described above.
A pulley 14 is attached to the rear end of the pulley 14, and its tip extends into the inner frame 4. and the rotating shaft 13
A connecting rod 15 is integrally provided at the tip of the connecting rod 15, and the base end of a link rod 16 is pivotally connected to the tip of the connecting rod 15. Further, a pin 17 implanted in the rotating body 2 is inserted into the tip of the link rod 16. Therefore, when the rotating body 2 is rotated, the pin 17 rotates the link rod 16, and the rotation of the link rod 16 causes the connecting rod 15 to tilt and the rotating shaft 13 to rotate. As the rotation shaft 13 rotates, the pulley 14 winds or unwinds the wire 20 connected to the spring 19 connected to the firing rod 18, thereby reducing the firing tension of the ball by the firing rod 18. Can be adjusted.

A switch 21 is provided inside the inner frame 4, and an operating piece 22 of the switch 21 faces the outer surface of the inner frame 4.
When the operation piece 22 is operated, the switch 21 is turned off and the operation of the firing rod 18 can be stopped.

In addition, since the rotating body 2 has a cylindrical portion 2' formed at the center inserted into the support shaft 6, the rotating body 2 and the support shaft 6 can be brought into sufficient contact and good electrical continuity can be achieved. There will be no contact failure.

As described above, according to the present invention, when a human body comes into contact with or comes close to the rotating body 2, the drive source is activated and pachinko can be played using the firing rod. Since the support shaft supporting the device does not rotate, an electrical circuit can be constructed by connecting lead wires directly or indirectly from the support shaft. Moreover, when the player operates the rotary body, the weight of his hand acts on the sliding contact surface between the inner circumferential surface of the cylindrical portion of the rotary body and the outer circumferential surface of the support shaft.

Therefore, there will be no contact failure or electrical conduction obstruction over a long period of time, and the structure is extremely simple, so it can be used in any pachinko machine.
