[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operating handle for a pachinko machine that uses a solenoid as a drive source for a ball firing device.

0002

[Prior Art] Various types of ball launchers have been developed for pachinko machines that use solenoids as the drive source for the launcher, and the flight distance of these types of ball launchers is generally adjusted by reducing the power supplied to the solenoid. This is done through control. A variable resistor is used to control 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 that uses a solenoid as a drive source and adjusts flight distance using a variable resistor is effective because of its simple structure. However, on the other hand, since the structure is simple, there are some disadvantages, such as the fact that it can be easily manipulated by players.

For example, if a variable resistor is placed inside the case of the operating handle provided on the front of a pachinko machine, and the dial fitted on the rotating shaft of the variable resistor is exposed to the outside of the case. , it functions satisfactorily as a flight distance adjustment device. However, it is inevitable that there will be a certain amount of gap between the dial and the case, so it is not possible to play a trick by inserting a foreign object such as a wire through this gap, or to insert a coin or other object in order to fix the flight distance. be. Therefore, the rotary shaft of the variable resistor may become deformed, causing poor contact, resulting in unstable flight distance or rendering the variable resistor useless.

[0005] Furthermore, since the operating handle is used as a hand to open or lift the front frame, it must be strong.

[0006]

[Means for Solving the Problems] The present invention has been proposed in view of the above, and provides a pachinko machine equipped with a ball launcher that uses a solenoid as a drive source and adjusts flight distance by changing the resistance value of a variable resistor. The operating handle has an assembly case that has a substantially hemispherical shape as a whole, and the assembly case has a cylindrical support section extending behind a dish-shaped bottom plate section, and a cylindrical support section extending from the bottom plate section.

The end face on the main body side is provided with a locking edge that can fit into the above-mentioned engaging edge, and the end face on the front case side is provided with an engaging stepped portion, and a part of the peripheral wall portion corresponds to the bulged portion. An inner case with a cutout and conductive treatment on the surface,
It consists of a mountain hat-shaped front case which has a locking step on the outer periphery that can fit into the locking step provided on the front end surface of the peripheral wall of the middle case, and the bulge of the case body has A variable resistor with a dial fitted on the rotating shaft is housed, and a stop switch operation button that stops the ball from being fired is exposed on the rising edge of the case body so that it can be operated externally. In addition to allowing external operation to be made possible through a cutout in the inner case, the positional relationship between the operation button and the dial is rationally arranged so that it is easy to operate when the player places his or her hand on the operation handle. The case is attached from the front side of the operating handle in a position that does not make it easy to disassemble.

[0007]

[Operation] The case body, middle case, and front case are attached to each other in a fitted state to form an operating handle, and the operating handle cannot be disassembled from the front side of the pachinko machine to adjust the flight distance. The arrangement of the dial and the stop switch for timing the firing of a batted ball becomes rational.
