[0002]

2. Description of the Related Art For example, in a portable portable compact disc player as shown in FIG. 9, its outer casing tends to be thin in view of portability and weight reduction. For this reason, conventionally, in order to prevent deterioration of mechanical strength due to thinning, a turntable on which an optical disc is mounted, an optical pickup device, and the like are rotatably mounted on a device body 101. A reinforcing plate 103 formed by sheet metal processing is attached to the back surface of the lid 102 to be attached. The reinforcing plate 103 also functions as a blind for the lid 102 by being attached to the lid 102.

For example, as shown in FIG. 10, the reinforcing plate 103 includes a boss 104 provided on the back surface of the lid 102,
It is attached to the lid body 102 by screwing self-tapping screws 106 and 107 to 105. However, the reinforcing plate 103 is fixed to the lid 1 by screwing.
When attached to 02, self-tapping screws 106, 1
In order to secure the effective screw length of 07, the boss 10
Since 4,105 become high (thick), a space for screwing is required. Further, if the screw length is shortened to shorten the effective screw length, there is a possibility that screw burrs may occur. Therefore, such a screw stop is not suitable for a portable machine, which is required to be downsized in terms of securing space.

In addition to this, as shown in FIG.
There is also proposed a method in which an adhesive paper 108 is attached to the back surface of the sheet and the reinforcing plate 103 is attached thereto. However, in such a method, it is necessary to make the bonding surfaces of the reinforcing plate 103 and the lid body 102 on the same surface, and it is possible if the lid body 102 is flat or close to the design, but the lid body 102 is curved. In some cases, the adhesive area cannot be secured. Therefore, when the lid 102 is opened and closed, the reinforcing plate 103
There is a risk of peeling. Further, since the adhesive paper 108 is affected by heat, when the lid is twisted at high and low temperatures, the reinforcing plate 10
3 may peel off. In addition, there is a drawback that it is difficult to position the reinforcing plate 103 at the time of bonding.

[0005]

Therefore, the present invention has been proposed in order to solve the above-mentioned conventional technical problems, and it is possible to securely attach the reinforcing plate to the lid without rattling. It is an object of the present invention to provide a highly reliable electric device that can be downsized.

[0006]

In order to achieve the above-mentioned object, an electric device according to the present invention comprises a lid body rotatably attached to the apparatus body, and a reinforcing plate attached to the back surface of the lid body. It is characterized in that the reinforcing plate is engaged with and stopped by a locking claw provided on the back surface of the lid body.

Further, the present invention is characterized in that a projection for bending the reinforcing plate is provided on the back surface of the lid or the reinforcing plate.

[0008]

In the present invention, since the reinforcing plate is engaged with the locking claw provided on the back surface of the lid and the reinforcing plate is attached to the lid, the reinforcing plate can be easily attached. Further, since the projection is provided on the back surface of the lid or the reinforcing plate, the projection bends the reinforcing plate, and this bending absorbs the backlash after attachment.
