DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gripping device for a pachinko machine in which a firing punch for applying a striking force to a pachinko ball is driven by an electric drive source.

[0002]

2. Description of the Related Art As is well known, various hitting and launching apparatuses have been developed in a pachinko machine using an electric drive source such as a solenoid or a motor as a drive source of a launching punch for applying a hitting force to a pachinko ball. As a method of adjusting the flight distance in the hit ball launching device, there is a method in which power supplied to a driving source is controlled. A variable resistor is used for controlling the power, and the resistance value of the variable resistor is changed by operating a dial or lever provided on the front side of the pachinko machine.

[0003]

A pachinko machine in which the flying distance is adjusted by a variable resistor is effective because of its simple structure, but on the other hand, its structure is simple.
There are many inconveniences, such as being easily mischievous by players. For example, when a variable resistor is arranged in a case of a gripping device for hitting and launching operation provided on the front of a pachinko machine, and an operation piece mounted on a rotating shaft of the variable resistor faces the outside of the case, Since it is inevitable that a certain amount of gap is formed between the operation piece and the case, a foreign object such as a wire may be inserted into the gap, or a coin or the like may be inserted to fix a flight distance. . Then, these loads will act directly on the rotation axis of the variable resistor,
The variable resistor may cause poor contact, resulting in unstable flight distance or uselessness. In addition, the grip device uses this as a clue to open the front frame,
You have to be strong to lift or lift.
On the other hand, the grip device must be easy and reliable to adjust the flight distance, and must not be tired even if the game is continued in the same posture for a long time.
