Abstract
Abstract A bucket (30 is so supported by a pair of supporters (54, 64) that it can move up and down, through vertical slits (60, 66) formed in the supporters (50, 64) and pins (40) formed on the bucket and entering the vertical slits. A guide member (80) can reciprocate horizontally, along one of the supporters (54). The guide member has slanted slits (84) into which the pins on the bucket are individually fitted. When a cartridge is horizontally inserted into the bucket, a slider (42) moves forward in conjunction with the cartridge, thereby rocking the interlocking body (100) retaining the guide member (80), to disengage the guide memberfrom the interlocking body. The guide member is moved in the cartridge retreating direction (3) by a tension spring (92), and the bucket (30) is lowered by the joint action of the slanted slits (84), the vertical slits (60) and the pins (40). Thus, a magnetic disk engages with the shaft of a motor (26). If an ejecting lever (110) is pushed in, the guide member (80) moves in the cartridge insertion direction (2) and the bucket (30) is raised by the action of the slanted slits, etc. Thus, the magnetic disk is disengaged from the motor shaft. At the same time, a stopper (142) is also raised, so that the cartridge (1) is retained by the stopper, If the ejecting level (110) is released, the stopper is then lowered, so that the cartridge is pushed out of the bucket by the slider (42).
