Benefits of technology

[0021] Due to the above structure, the rigidity of the hinge can be maintained sufficiently high, and the signal wires for connecting the first housing with the second housing can be easily incorporated and laid.

Problems solved by technology

Therefore, the following problems may be encountered in the conventional folding electronic apparatus.
Therefore, the rigidity of the hinge is not sufficiently high compared with the rigidity of the structural members of the chassis.
Accordingly, it is difficult to maintain the accuracy of a rotary shaft to be high.
In the conventional folding electronic apparatus, when the movable portion and the stationary portion are connected to each other by the signal wires at the time of assembling, the assembling work is complicated.
Therefore, the rigidity of the hinge is not sufficiently high.
Accordingly, it is difficult to maintain the accuracy of the rotary shaft to be sufficiently high.
Further, there is a possibility that the hinge is independently deformed when a shock is given to the apparatus.
Furthermore, in the conventional folding electronic apparatus, it is difficult to incorporate the signal wires extending between the movable portion and the stationary portion.

Abstract

A folding electronic apparatus is proposed, the rigidity of the hinge of which is sufficiently high, in which signal wires for connecting a movable portion with a stationary portion can be easily incorporated. The apparatus includes: a stationary portion (2) and a movable portion (3) which are connected to each other by a hinge (4), capable of being opened and closed, the hinge includes: a pipe portion (32) having a first slit (35) on a side wall, the pipe portion being attached to one of the movable portion and the stationary portion; and a hollow shaft (24) having a second slit (25) on the side wall, the hollow shaft (24) being attached to the other of the movable portion and the stationary portion, the hollow shaft (24) being engaged inside the pipe portion, wherein the first and second slits extend to positions shifted from an engaging portion of the pipe portion with the hollow portion in the axial direction and define opening portions (25a, 35a) of the first and second slits.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a folding electric apparatus. More particularly, the present invention relates to a folding electric apparatus having a hinge (an opening and closing mechanism).
