Apparatus opening and closing mechanism, and information apparatus

摘要

An apparatus opening and closing mechanism includes: a slide mechanism by which a first casing and a second casing are slidably connected to each other and which effects transition of position state of the first casing and the second casing between a closed state and an open state; and a hinge mechanism by which the first casing and the second casing are rotatably connected to each other. The slide mechanism includes: a first holder fixed to the first casing; a second holder which is fixed to the second casing and by which the first slider is supported so as to be movable in the sliding direction; and an elastic member which has one end fixed to the first holder and the other end fixed to the second holder and which extends and contracts according to movement of the first casing and the second casing at the time of sliding.

1. An apparatus opening and closing mechanism comprising:
a roller; a slide mechanism by which a first casing and a second casing are slidably connected to each other and which permits transition of position state of the first casing and the second casing between a closed state in which an overlapping region of the first casing and the second casing is maximized and an open state in which the overlapping region of the first casing and the second casing is minimized; and a hinge mechanism by which the first casing and the second casing are rotatably connected to each other, wherein the slide mechanism includes
a first holder fixed to the first casing,a second holder which is fixed to the second casing and by which the first holder is supported so as to be movable in a sliding direction, andan elastic member which has one end fixed to the first holder and the other end fixed to the second holder and which extends and contracts according to movement of the first casing and the second casing at the time of sliding,the second casing having a plurality of keys arranged on a surface thereof,the roller being connected to the first casing and configured to roll on at least some of the keys the second casing when slidable movement occurs between the first casing and the second casing, said roller being positioned to ensure that during the slidable movement contact between the plurality of keys and a surface of the first casing which faces the surface of the second casing having the plurality of keys thereon is prevented from occurring, the elastic member is so configured that the elastic member contracts most in an in-sliding state of the first casing and the second casing and that its extension amount in the closed state is smaller than its extension amount in the open state, and the hinge mechanism becomes able to function when the first casing and the second casing are brought into the open state.
