ABSTRACT:
A disk device including a guide, formed in a housing, having an inclined guide portion and a straight-line guide portion. A moving member moves along the guide. The moving member is affixed to a wire, and the wire is wound upon a biasing pulley. A small-diameter pulley is formed integrally with the biasing pulley, and a spring is provided at a biasing wire wound upon the small-diameter pulley. When the moving member is pushed into the disk device by a cartridge, the shutter is opened. The moving member is also used to eject the cartridge. Even when the resilient force of the spring is large, the reaction force, produced as a result of cartridge insertion, is small, and the ejection stroke of the cartridge is large. In a conventional disk device for loading a cartridge therein, both a mechanism for opening the shutter of the cartridge, and a mechanism for ejecting the cartridge are required. When these mechanisms are formed into a single mechanism, the reaction force, produced when inserting the cartridge, is large, and a sufficiently long ejection stroke cannot be obtained. The disk device of the invention makes it possible to overcome these problems.
