Abstract
A drive arrangement effects movement of a disk conveying portion to a plurality of first positions and to a second position relative to a case and a rotatable turntable. The drive arrangement includes a driving gear, a slide member having a gear portion engaging the driving gear, and a movable slide plate engaged by the slide member, the slide plate having a stepwise cam portion which effects movement of the disk conveying portion between its positions. The disk conveying portion has two rotatable rollers which can engage an edge of a disk in the case when the disk conveying portion is in one of its first positions, and which rotate in order to extract the disk. As the disk conveying portion moves to its second position, the disk supported by the rollers moves to the turntable, and a clamp member is moved from a retracted position to a clamping position to hold the disk against the turntable, after which the rollers are disengaged from the disk.
