ABSTRACT:
A disc player capable of immediately ejecting an inserted disc of a type having a diameter other than a predetermined diameter. If a disc having a predetermined diameter is inserted, a pair of detection pins are moved away from each other so that both of first and second switches are switched off. If the disc is further inserted, one of the detection pins causes a detection lever is moved such that a third switch is switched off. At this time, a motor is started so that a roller is rotated and the disc is drawn into the disc player. If a small disc has been inserted, all of the first, second and third switches are not switched off. When the first switch or the second switch has been switched off, a timer starts. If a discrimination is performed that the inserted disc is not a disc of a type having the predetermined diameter, then the roller is rotated in the ejection direction so that an ejecting operation is immediately performed.
