  • Patent number: 4794478
    Abstract: A cassette holder which includes a cassette stage for holding a cassette, along with a pair of X-shaped pivotal right and left link mechanisms for holding the cassette stage. Each of the link mechanisms include a first end which is held by a chassis whereby the link mechanisms support the cassette stage in such a manner that the cassette stage moves upward and downward relative to the chassis along a predetermined path. Lid supporting plates are pivotally held against the right and left walls of the cassette stage, with each of the plates being engaged with one end of each of the X-shaped pivotal link mechanisms. The lid supporting plates are pivoted relative to the cassette stage in accordance with an upward and downward movement of the cassette stage.

  • Patent number: 4561084
    Abstract: A disk loading and unloading system (5) including a disk holding section (10, 11, 15, 16, 23) mounted for pivotal movement with respect to a main body of the system. When the disk holding section is pivotally moved outwardly away from the main body, the disk holding section moves to an upper position in which at least a portion of a disk (6) supported in the disk holding section clears the disk holding section and is exposed to view. Thus the disk can be removed from the disk holding section by holding its side edge by hand.
