Open/close detection device

摘要

In an open/close detection device of equipment including a casing, a lid body which is rotatably supported on the casing and a hinge member which mounts a frame body thereof on one of the lid body and the casing and makes a shaft body which is projected from the frame body rotatably support the other of the lid body and the casing, the hinge member arranges a movable contact which is integrally rotated with the shaft body and a stationary contact which is brought into slide contact with the movable contact in the frame body, whereby the rotation of the lid body is detected in response to the slide contact between the movable contact and the stationary contact which is generated by rotation of the shaft body.
