ABSTRACT:
A disc playback device comprises a loading device for transferring a disc or a case housing a disc between an eject position in which the disc or the disc case is inserted and ejected and a playback position in which the disc can be played, thereby performing loading and eject modes, a feed device for feeding a pickup head which reads data recorded on the disc in a playback mode in a radial direction of the disc set in the playback position, and a single drive source for driving both the loading device and feed device. The single drive source drives the feed device and the loading device is driven through the feed device. A carrier having a carrier rack moved by the drive source and a carrier pinion meshing with the carrier rack are provided in a drive system for a loading pinion meshing with a disc case rack and the loading pinion is connected to the carrier pinion through clutch means.
