Description

[Detailed Description of the Invention] This invention relates to a speaker mounting device for a pachinko machine that generates various sound effects from the speaker to significantly enhance the interest of the game.

Conventionally, in pachinko machines that generate various sound effects from a speaker to increase the interest of the game, the speaker is attached to an opening/closing panel to which a ball tray is attached (see Utility Model Publication No. 56-68575), or It is attached to the bottom of the (Utility Model Publication No. 57-38205). This opening/closing panel has a structure in which it can be opened horizontally toward the player by means of, for example, a screw attached to one end thereof.

Also, instead of installing the speaker on the opening/closing panel, it was installed on the curtain board below the pachinko machine.
(Japanese Utility Model Publication No. 175472/1983).

The speaker provided on the opening/closing panel is made sufficiently long so that the wiring extending from the speaker can be opened. Therefore, a long wiring may protrude from the opening/closing panel when the opening/closing panel is closed, or may break if the opening/closing panel is strongly pressed while the wiring is protruding from the opening/closing panel.

Furthermore, when the speaker breaks down, the speaker must be replaced with the opening/closing panel open, but since the opening/closing panel in the open state is extremely unstable, replacing the speaker is complicated. .

On the other hand, if the speaker is not attached to the opening/closing panel but is installed on the curtain plate or back mechanism, the speaker can be easily accessed without having to work in an unstable state with the front frame open. Since the speaker is not within reach, maintenance and inspection of the speaker is extremely difficult, and replacement and assembly is almost impossible, making it completely impractical.

Furthermore, with conventional speaker mounting devices, the speaker sometimes loosens and falls off due to vibrations during gaming.

This invention was made based on the above-mentioned circumstances, and it is possible to easily and reliably perform maintenance inspection work or replacement and assembly work on speakers in pachinko machines, and also to be able to reliably mount the speakers. It is an object of the present invention to provide a speaker mounting device that does not require long wiring.

The outline of this invention to achieve the above purpose is as follows:
In a pachinko machine, a speaker holder with an open rear surface and a speaker housed inside is removably fitted to a mounting member provided on the front of a lower game board located below the upper game board, and the speaker holder is removably fitted to the front of the mounting member. This is a speaker mounting device for a pachinko machine in which the speaker is held by bringing the rear end of the speaker into contact with the rear end of the speaker.
