Abstract

PROBLEM TO BE SOLVED: To prevent the opening and closing of a cover by mischief without needing the strong power by mounting a cover on a case to cover an opening part, locking a mount condition of the cover to the case, and performing the locking and unlocking operation from a front surface side of the cover by an operational magnet. SOLUTION: A slide member 28 is moved by an operational magnet, and a cover 2 is brought into contact with a front surface face of a case 1. The cover 2 is moved downward, so that a projection 24a of an upper latch 24 is inserted into hole 22a of an upper bracket 22, and a projection 25a of lower latch 25 is inserted into a hole 23a of a lower bracket 23. When the operational magnet is separated from the cover 2, the slide member 28 is pushed by a return spring 30 to be moved. The connecting state of the upper latch 24 and the upper bracket 22 is locked, and the locking is performed in a condition that the cover 2 is mounted on the front surface of the case 1. Whereby the removement method of the cover 2 can not be found, and the fracture of an equipment by mischief can be prevented. Further the locking can be easily released, and the cover 2 can be mounted and demounted without needing the strong power.
