Claims (1)

[Scope of Claim for Utility Model Registration] (1) A mounted printed wiring board is removably stored in a case, and an electrical connection with an external device is turned on and off via a connector provided in the case. In the mechanism, (a) a locking member provided on the printed wiring board, capable of taking a predetermined movement with respect to the printed wiring board, and having a locking portion with the case and a switch operation portion; (b) When the printed wiring board is stored in a predetermined position of the case and the locking part of the locking member is engaged with a locked part provided on the case, the operation part of the locking member is turned on in conjunction with, and
the locking part is disengaged from the locked part,
An attachment/detachment mechanism for a printed wiring board, comprising: a switch that is turned off in conjunction with an operating section of the locking member when the printed wiring board can be pulled out. (2) In the mechanism described in claim 1, the locking member is supported movably by a predetermined distance in a direction substantially parallel to the surface of the printed wiring board and substantially perpendicular to the direction of attachment and detachment. What is claimed is: 1. A printed wiring board attaching/detaching mechanism, characterized in that the printed wiring board attachment/detachment mechanism is provided with a protruding locking portion and an operating portion mechanically connected to an operating tool of the switch. (3) In the mechanism set forth in claim 1 of the utility model registration claim, the locking member is provided on the main locking member for pulling out the printed wiring board, and on this main locking member, and the locking member is provided on the main locking member and The main locking member is provided with an auxiliary locking member that takes a predetermined movement when the auxiliary locking member moves, and another switch that is operated in conjunction with the movement of the auxiliary locking member. A mechanism for attaching and detaching a printed wiring board, characterized in that the predetermined movement of the stopper member is blocked or released, and the other switch is turned on or off.
