<P>PROBLEM TO BE SOLVED: To provide a retainer which moves a moving unit without generating a sound and retains its position, makes a driving member consume no electric power when retaining the position of the moving unit, and can reduce the power consumption of the driving member and retainer itself during the movement of the moving unit. <P>SOLUTION: Retaining units 41A and 41B can move in a first lever moving direction and a second lever moving direction, and each include: a pin member 43 attached to a lever member 31 not to move in the first lever moving direction and second lever moving direction; a first elastic member 51 which absorbs the kinetic energy of the lever member 31 when coming into contact with a moving unit 10 to contract to its limit; and a second elastic member 53 which is harder than the first elastic member 51. The second elastic member 53 absorbs all the kinetic energy of the lever member 31 which is not absorbed by the first elastic member 51 after the first elastic member 51 contracts to its limit. <P>COPYRIGHT: (C)2012,JPO&INPIT |
