Abstract
A driving device in which when a cartridge is inserted with a correct orientation, a retainer protrusion of a drawing-in member engages a retainer recess of the cartridge, so that a sliding shaft of the drawing-in member slides along a guide surface to draw in the cartridge. When the cartridge is inserted with a reversed orientation, the drawing-in member is pushed sideways, so that the sliding shaft slides along a relief guide portion at the exterior side of the guide plate, causing the drawing-in member to be driven in the X1 direction. Since the drawing-in member is driven along the relief guide portion, locking of the mechanism does not occur. Accordingly, it is possible to prevent locking of a mechanism, which occurs when the cartridge is inserted with a wrong orientation, and the drawing-in member, which is not retained by the cartridge, is driven in the drawing-in direction, in a disk device in which a drawing-in member is used to draw in a cartridge of, for example, a mini-disk.
