Description

Electronics

The present invention relates to an electronic apparatus provided with a lid that opens and closes with respect to a casing body by rotating around a hinge portion.

As a conventional structure provided with a lid that opens and closes with respect to the housing body, for example, there is a guard barrier disclosed in Patent Document 1. This guard barrier has a hinge portion in which a rotation shaft provided on a cover, which is a lid, is fitted in a shaft hole of a box-type frame.

JP 2001-283667 A

Conventionally, since the lid or the housing body is bent and the shaft of the hinge portion is fitted into the shaft hole, there is a problem that the amount of engagement between the shaft and the shaft hole cannot be increased.
For example, as shown in FIGS. 1A and 1B, when the lid 100 is assembled to the housing 101, conventionally, the lid 100 is bent and the shaft 102 is fitted into the shaft hole 103. It was.
In this configuration, as shown in FIG. 1B and FIG. 1C, the lid 100 is mounted on the housing unless the bending amount a of the lid 100 is larger than the amount b of engagement between the shaft 102 and the shaft hole 103. 101 can not be assembled. For this reason, when the lid body or the housing body is formed of a member that does not bend greatly, the amount of hooking must be inevitably reduced, and the lid body easily falls off.

The present invention has been made to solve the above-described problems, and an object of the present invention is to obtain an electronic device capable of increasing the amount of engagement between the shaft and the shaft hole in the hinge portion of the lid.

According to another aspect of the present invention, there is provided an electronic apparatus including a housing body and a lid body that rotates about the hinge portion to open and close the housing body, wherein the hinge portion is one of the lid body and the housing body. And a bearing portion having an axial hole along the hinge axis, and a shaft portion provided on the other side of the lid or the housing body and having an axis along the hinge axis, and slid along the hinge axis. And a rotation support part that abuts the bearing part or the shaft part of the lid body in a state where the shaft is fitted in the shaft hole and restricts the slide in a direction in which the shaft is detached from the shaft hole.

According to this invention, there is an effect that the amount of engagement between the shaft and the shaft hole in the hinge portion of the lid can be increased.
