Patent ID: 8306459

Claim:
An opening-and-closing mechanism comprising: an opening-and-closing member that rotates about a rotational center with respect to a body to thereby open and close one surface of the body; a holding member that is disposed on the body and is rotatably coupled in a position that is displaced in a vertical direction with respect to the rotational center; a sliding member that is disposed so as to be slidable with respect to the holding member along a longitudinal direction of the holding member, whose end portion is coupled to the opening-and-closing member, and that slides with respect to the holding member in accompaniment with rotation of the opening-and-closing member; a braking member that is formed by a material that has elasticity and whose coefficient of friction with one of the sliding member or the holding member is larger than a coefficient of friction between the other of the sliding member or the holding member and the one of the sliding member or the holding member, the braking member sliding with respect to the one of the sliding member or the holding member in accompaniment with the sliding member sliding with respect to the holding member to thereby generate a braking force by a frictional force with the one of the sliding member or the holding member; and a pressing member that is disposed on the other of the sliding member or the holding member, the braking member being mounted at the pressing member, and the pressing member pressing the braking member against the one of the sliding member or the holding member.
