Claims

[Scope of Claim for Utility Model Registration] An equipment case that includes a movable part inside and has an opening facing the movable part; A cover that is provided in the opening of the equipment case so that it can be opened and closed; and a cover that is rotatable. a knob provided in the device case and having a locking piece that engages with the device case depending on the rotation angle position to lock the cover in a closed state; Therefore, the knob is biased in one direction in the sliding direction, and when the knob is rotated in a direction to lock the cover in the closed state, the locking piece is biased in the other direction in the sliding direction against the first spring. a lever to be slid; a power on/off switch for the device provided at a position away from the opening in the device case; a rotating member that is rotatably provided and has an operating piece that is rotated by sliding the lever in the other direction and turns the switch on and off according to the rotational angular position; a second spring that biases the member to rotate in the direction in which the switch is turned off, and the lever is provided with a second spring that contacts the lock piece when the knob is rotated in the direction to lock the cover in the closed state. An engaging piece that touches the lever and slides the lever in the other direction is provided, and a pressing piece that presses the rotating member is formed perpendicular to the sliding direction,
An interlock switch mechanism characterized in that the interlock switch mechanism further comprises: a cover member that covers the periphery of the engaging piece except for the surface that comes into contact with the locking piece.
