ABSTRACT:
A player for selecting and playing a disc (such as a CD) capable of accurately locating its moveable portion for selecting and playing the disc and accurately clamping a selected disc. The moveable portion for selecting and playing the disc is provided with a first and a second moveable chassis. When drive levers are driven by the force of a motor, the second moveable chassis is moved upwards/downwards by a link mechanism. The first and second moveable chassis are mutually locked by locating/locking plates to be moved upwards/downwards. When the first and the second moveable chassis have been moved to the position for selecting the discs from a magazine, the locating/locking plates are moved to be engaged to locating portions formed into plural stages of locking mechanism portions provided for the case of the player so that the first moveable chassis is properly located. As a result, the relative position between the moveable portion and the disc in the magazine is determined accurately.
