Disc apparatus

Abstract

A loader conveys a holder, carrying thereon a disc cartridge, between a cartridge ejection position and a reproducing/recording position. The loader has an engaging part which engages with a mechanical lock mechanism so as to release a holder pin in the mechanical lock mechanism from its locked condition in order to hold a movable chassis in a floating condition with respect to a stationary chassis and to lock the holding pin in the mechanical lock mechanism so as to fix the movable chassis to the stationary chassis when the holder has been moved to the cartridge ejecting side. When the holder is moved to the reproducing/recording position, the holding pin provided on the holder engages with a shutter closing spring so as to retract an engaging part at the front end of the shutter closing spring through an opening in the holder in order to prevent the disc cartridge from making contact with the shutter closing spring, thereby making it possible to give a satisfactory feeling of insertion of the disc cartridge and avoid damaging the disc cartridge. Further, a rack in a loader feed mechanism is composed of two rack members which are linked together so as to decrease the operating length for moving the loader.
