Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for mounting a key switch which is operated by a dedicated key on a base box for a gaming machine.

[0002]

2. Description of the Related Art In current pachinko machines and slot machines, game contents are controlled by a control board including a microcomputer, and a game machine board box for accommodating the control board is attached to almost all models. .

[0003]

Since the gaming machine base box is a central part for controlling the contents of the game, the box body and the lid are sealed so as not to be unduly modified. It has a structure that cannot be modified. By the way, in recent years, in a so-called digital pachinko machine that changes the winning device into a special prize game state by combining, for example, three sets of numbers, a switch for switching the probability that the numbers and the like are aligned to several stages may be provided in the game machine base box. is there. Since this switch directly affects the ball launch rate of the pachinko machine, a key switch operated by a dedicated key is used so that only a specific person such as the manager can operate it. Thus, the mounting structure of the key switch in the game machine base box is easy from the outside of the game machine base box so that the inside of the game machine base box is not touched through the lead wire of the key switch. It should not be removable, and it is desirable that it can be easily attached without using a tool such as a screwdriver. Therefore, the purpose of the present invention is to
An object of the present invention is to provide a key switch mounting structure that can be easily mounted without using a tool such as a screwdriver and that cannot be removed from the outside of the gaming machine base box after mounting.

[0004]

In order to achieve the above objects, the present invention provides a key switch mounting structure having the following requirements (1) to (3). The body of the key switch should be shaped so that it can be inserted into the mounting hole formed in a part of the game machine base box. A brim portion that engages with the edge of the mounting hole is formed on the front edge of the key switch. An elastic stopper for retaining is attached to the body of the key switch so that the tip end facing the flange side is lifted from the body and the other end is fixed to the body. Between the tip of the elastic stopper and the collar portion, there is formed a gap that is approximately the same as or slightly wider than the plate thickness of the game machine base box.

[0005]

When the body of the key switch is inserted into the mounting hole from the front of the game machine base box, the tip of the elastic stopper is pushed into the inner peripheral edge of the mounting hole and enters. Then, when the key switch is inserted until the flange portion of the front plate hits the periphery of the mounting hole, the tip portion of the elastic stopper disengages from the mounting hole and expands. In this case, the tip of the elastic stopper engages with the back surface around the mounting hole, and the key switch is fixed in a non-removable state.
