DISK DISCRIMINATING DEVICE, DISK INSERTING/EJECTING DEVICE, AND DISK DEVICE

摘要

A challenge of the invention is to provide a disc device for electrically identifying and determining the number of discs inserted into the disc device and controlling the mechanism of the disc device based on the identification result, so that stable disc insertion and ejection can be realized and damage to the mechanism of the disc device and the disc can be decreased. Roller members (101 and 102) for coming in contact with a disc (300) 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 (100). A lever member (109) for engaging a lever engagement part (102a) of a roller member (102) and capable of rotating with a stem member (109a) as a supporting point and a push switch (110) for detecting displacement of the lever member (109) are provided. If the disc (300) is inserted into the device, the roller member (102) displaces in the up direction of the disc (A direction in a figure), the lever member (109) displaces in an H direction in the figure, and the displacement of the lever member (109) is detected by the push switch (110), whereby the thickness of the disc inserted into the device is detected.
