Description

  The present invention relates to an electronic apparatus including two housings having hinge portions that are rotatable.

  In a conventional electronic device, a casing having a display unit (hereinafter referred to as an upper casing) and a casing having an operation unit such as a numeric keypad or a cross key (hereinafter referred to as a lower casing) are pivotally supported (hereinafter referred to as pivots). The hinge part). This makes it possible to construct a large display unit for viewing in a state in which the upper housing and the lower housing are opened and used (hereinafter referred to as “open”), and compact in a state where the upper housing and the lower housing are closed (hereinafter referred to as “closed”). Therefore, it has two advantages of portability.

  In such an electronic device, when the upper housing and the lower housing are in a closed state, the upper housing and the lower housing are displaced or rattled due to rattling of the hinge portion. There was a problem. Therefore, a technique for solving such a problem has been disclosed (for example, see Patent Document 1).

  As shown in FIGS. 19 and 20, the portable terminal 100 described in Patent Document 1 includes an upper casing 101 having a display unit and a lower casing 102 having an operation unit, and a hinge unit (not shown). ) To be relatively rotatable.

  Two buffer members 104 are arranged in parallel with a rotating shaft (not shown) for folding at the end of the upper housing 101 opposite to the hinge portion on the inner surface where the display unit 103 is provided. The buffer member 104 prevents wrinkles caused by the surface of the upper casing 101 on the inner side touching the inner surface of the lower casing 102 when the portable terminal 100 is in the closed state, or the upper side in the closed state. This is an elastic material for preventing the displacement between the housing 101 and the lower housing 102.

  Further, at the end of the lower housing 102 opposite to the hinge portion on the inner side surface where the key operation unit 105 is provided, the position is adjacent to each of the two buffer members 104 when closed. One buffer member 106 is disposed. The buffer member 106 is in contact with the buffer member 104, thereby restricting movement in the width direction between the upper housing 101 and the lower housing 102 when the mobile terminal 100 is in a closed state. This prevents backlash between the upper housing 101 and the lower housing 102 in the closed state.
