Abstract
A disc cartridge adapter that is capable of driving a different size of disc cartridges with the same disc driver. In the adapter, a driving power transfer device absorbs a difference in a shutter travel range having a different size from each other to drive shutters of a small-scale disc cartridge. A body is provided with a receiving space for receiving the small-scale cartridge. Accordingly, the small-scale cartridge can be driven with a disc driver for driving a large-scale cartridge.
Claims15
A disc cartridge adapter for driving a small-scale cartridge having a shutter travel range relatively smaller than a shuttle travel range of a large-scale cartridge, said adapter comprising:
- a body with a receiving space for receiving the small-scale cartridge;
- and
- a driving power transfer device linked to the body, said driving power transfer device for absorbing a difference in a shutter travel range between the small-scale cartridge and the large-scale cartridge and including
- support sliders on the sides of the driving power transfer device,
- a first slider member installed on the body linearly-movably,
- a second slider member linked to the first slider member to drive a shutter of the small-scale cartridge, and
- a first elastic member for applying an elastic restoring force connected between the support sliders, said elastic member including a spring for generating an elastic restoring force,
- wherein the support sliders are linked to the first slider member while leaving the spring therebetween and restraining the second slider member for preventing a motion of the second slider member.
A disc driving system, comprising:
- a disc drive for a relatively large-scale disc cartridge with a first shutter travel range;
- a small-scale disc cartridge with a second shutter and a second shutter travel range;
- an adapter defining a cavity for receiving the small-scale disc cartridge and including:
- a driving power transfer device, said driving power transfer device for absorbing a difference in the shutter travel range between the small-scale cartridge and the large-scale cartridge and including
- support sliders on the sides of the driving power transfer device,
- a first slider member installed on the adapter linearly-movably,
- a second slider member linked to the first slider member to drive the second shutter;
- and
- a first elastic member for applying an elastic restoring force and connected between the support sliders, said elastic member including a spring for generating an elastic restoring force,
- wherein the support sliders are linked to the first slider member while leaving the spring therebetween and restraining the second slider member for preventing a motion of the second slider member.
A disc cartridge adapter for driving a first shutter of first cartridge having a first travel range relatively smaller than a second travel range of a second shutter of a second cartridge, said adapter comprising:
- an opener for opening the first shutter in a first and a second direction, said opener including
- a slider for moving the shutter in the first and second direction,
- a first absorbing region on a first side of the slider for absorbing slider movement in the first direction, and
- a second absorbing region on the second side of the slider for absorbing slider movement in the second direction.
