ツチ装置。 A door opening/closing switch device that is linked to the opening and closing of a dustproof door that covers the opening of a floppy disk unit includes a dustproof door that can be opened and closed freely, a light emitting element and a light receiving element that are provided near the dustproof door, and a light emitting element and a light receiving element between these two elements. a photo interrupter that detects conduction/blocking of the optical path of the photo interrupter; a tongue portion made of an opaque thin plate that enters and exits the optical path of the photo interrupter; and a guide shaft that causes the tongue portion to enter and exit the optical path of the photo interrupter. A button mechanism that is pressed in response to the closing operation of the dustproof door and causes the tongue to block the optical path, and a button mechanism that is wound around the outside of the guide shaft and pushes back the button member with elastic force when the dustproof door is opened. , a coil spring that opens the optical path from the tongue portion, and a conduction between the optical path of the photo interrupter;
1. A door opening/closing switch device comprising a detection means for detecting an open/closed state of a dust-proof door by detecting a shut-off state.
