<P>PROBLEM TO BE SOLVED: To suppress a lock state of a lock member from easily being released. <P>SOLUTION: A lock member has an engagement member 33 engaged with a recess 111, a pressing member 36 for pressing the engagement member 33 so that the engagement member 33 is positioned to a position engaged with the recess 111, a grappling member 332 that is formed on the engagement member 33 and grapples a tip portion of a dedicated key composed of a plate with a T-shaped tip, and a grappling member cover 31 that restricts a member other than the dedicated key from accessing the grappling member 332. A plurality of engagement members 33 are arranged in directions crossing vertically with a pressing direction of the pressing member 36; the grappling member 332 is individually formed for each engagement member; the pressing member 36 individually presses each engagement member and applies a force for each engagement member by the dedicated key against a force that the pressing member 36 presses to position each engagement member to a position not engaged with the recess 111, thereby allowing an armoring cover 2 to detach. <P>COPYRIGHT: (C)2012,JPO&INPIT |
