Description

  The present invention relates to an operation unit cover device provided to prevent an inadvertent touch to an operation unit of a device such as a disk tray open / close switch in a DVD deck.

A disc tray such as a DVD deck or a personal computer is provided so as to extend to the front of the main body of the DVD deck or personal computer. An operation unit such as a switch for opening and closing the disc tray is provided on the front surface of the main body of the DVD deck or personal computer, and the disc tray can be opened and closed by simply touching the operation unit.
When the disk tray is opened, the tray extends to the front surface of the apparatus. However, the disk tray is used to place a thin disk, and in the extended state, the disk tray is easily broken.

In this way, the opening / closing operation section operates by lightly touching, and such an operation causes a fragile disc tray to extend. Therefore, there is a high risk that the disc tray extends due to careless touch on the operation unit such as a child or a pet, and in that state, the disc tray is broken due to the mischief of the child or the pet.
From the above background, it is necessary to prevent inadvertent touch to the opening / closing operation unit.

In view of this demand, conventionally, a plate-like magic tape (registered trademark) is attached to the upper surface of the switch portion of a personal computer, and the upper portion of the switch portion is drilled from the plate-like one. A concave part is formed so that only the part can be exposed, and a plastic plate with a velcro tape attached to the lower surface is placed on the upper surface. A personal computer switch safety device has been proposed (see Patent Document 1).
Japanese Utility Model Publication No. 5-97025

The personal computer switch safety device disclosed in Patent Document 1 has a structure in which a plastic plate serving as a cover body is fastened with a velcro tape, and since the velcro tape is easily detached, a child's mischief cannot be reliably prevented.
In addition, since the plastic plate that is the cover body overlaps the mounting part in plan view in the cover state, there is a possibility that it can be used as a cover for the main power switch of a personal computer. If a switch is provided on the front surface of the disk tray, the disk tray becomes inoperable and cannot be used.

  Even in the case of a DVD deck, since various operation units and a display are provided on the front surface where the operation unit for opening and closing the disk tray is provided, the cover body and the mounting portion for attaching the cover body are viewed in plan view. However, in reality, only a very limited number of cases can be handled.
