A disk transport mechanism for a disk player employs a fixed disk guide to support one edge of a disk and drive-side disk guide, with a revolving belt, to support and drive an opposite edge of the disk. The revolving belt is supported at two points by pulleys. The disk is held between the fixed and drive-side disk guides to press the revolving belt against the disk edge causing the disk to roll along the fixed disk guide. The fixed and drive-side disk guides are movably supported on a chassis and urged together by a spring. When a disk is transported to a playback position, the disk guides are separated to disengage the disk by a rack and pinion mechanism. The rack and pinion mechanism employs a pinion gear coaxially connected to one of the pulleys supporting the revolving belt. A drive gear, also coaxially connected with the pinion gear and pulley, is driven by an a motor on the chassis through an extensible transmission to power the revolving belt. The same motor and transmission shifts the drive-side disk guide laterally to separate the disk guides for playback by pivoting a rack, pivotably mounted on the chassis, toward the pinion gear to mesh with it. Thus, a single motor is used to drive both the disk transport mechanism and the separation mechanism that frees the disk for playback. <IMAGE> |
