(FIG. 8) is a schematic view showing an example of a conventional structure in which the above () is disposed, and FIG.

In the figure, in this structure, the opening that is opened and closed by the cover 51.
The apparatus main body 50 having 52 is provided.

When the unit 53 is attached to the inside of the device main body 50, the unit 53 is inserted through the opening 52 and positioned at a predetermined position, and then a fastening portion such as a screw (not shown).
It is fixed in the main body 50 of the device. Further, after the attachment, the opening 52 is closed by the cover 51, and the unit 53 is hidden from the outside. The cover 51 is rotatably attached to one end of the opening 52 via a hinge (not shown), and can be closed and locked releasably by a locking means 54.

The locking means 54 is composed of a fastening component 55 attached to the apparatus main body 50 side and a fastening component 56 attached to the cover 51 side. Of these, fastening parts on the device body 50 side
55 integrally includes a fixing piece 55a fixed to the inner surface of the opening 52 with a screw (not shown), and a restricting piece 55b bent inward at a substantially right angle by the fixing piece 55a. Further, the restriction piece portion 55b is provided with a lock hole 55c into which the fastening component 56 is inserted and engaged.

Then, in a device that requires high-density mounting, as seen in this embodiment, the dimension 1 of the frontage inside the protruding end of the restriction piece 55b is formed smaller than the width L of the unit 53. In many cases. Therefore, when attaching the unit 53 to the device main body 50, open the unit 53 before the fastener 55 is attached.
