<P>PROBLEM TO BE SOLVED: To provide a technique enabling prevention of a damage to a swinging member of a cover or the like based on a novel technical concept. <P>SOLUTION: A first stopper part 23F and a second stopper part 23G for regulating the swinging of a front cover 19 are disposed at an arm part 23. The first stopper 23F is elastically displaceable to the direction of releasing from a state of engaging with a boss part 25, and the second stopper 23G is located at the forward side of the first stopper part 23F in the swinging direction. With the configuration, the first stopper 23F is elastically displaced to the direction of releasing from the state of engaging and a reaction from the front cover 19 felt by a user is changed when the user applies an excessive amount of force to the front cover 19. Therefore, the user can detect that the excessive amount of force is applied to the front cover 19, thereby enabling prevention of a damage to the front cover 19. <P>COPYRIGHT: (C)2012,JPO&INPIT |
