ABSTRACT:
A disc device is for electrically identifying and determining the number of discs inserted into the disc device. Roller members for coming in contact with a disc inserted into the device, transporting the disc, and inserting and ejecting the disc are provided in the vicinity of a disc insertion slot of a cabinet. A lever member for engaging a lever engagement part of a roller member and capable of rotating with a stem member as a supporting point and a push switch for detecting displacement of the lever member are provided. If the disc is inserted into the device, the roller member displaces in the up direction of the disc (A direction in a figure), the lever member displaces in an H direction in the figure, and the displacement of the lever member is detected by the push switch, whereby the thickness of the disc inserted into the device is detected.
