Abstract
A disc cartridge that is adapted to receive a small-size optical disc and is compatible with a large-size disc cartridge. In the disc cartridge, first and second shutters open and close an opening. A connector links the first shutters to the second shutters as any one of the first and second shutters is driven.
Claims13
A disc cartridge with gearing shutters including a body in which an opening is formed and an optical disc is received, comprising:
- first and second shutter members, formed on an exterior of the body, for opening and closing the opening;
- and
- a connecting mechanism for linking the first and second shutter members and driving one of the first and second shutter members, as the other shutter member is driven,
- wherein when one of the first and second shutter members is driven, the connecting mechanism moves the other shutter member in a direction contrary to the driven shutter member, and
- wherein the connecting mechanism comprises:
- a pinion installed rotatably within the body;
- a first linear rack toothed into the pinion and coupled with the first shutter member;
- and
- a second linear rack toothed into the pinion in such a manner to be symmetrical to the first linear rack and having one side coupled with the second shutter member.
A disc cartridge with gearing shutters including a body in which an opening is formed and an optical disc is received, comprising:
- first and second shutter members, formed on an exterior of the body, for opening and closing the opening;
- and
- a connecting mechanism for linking the first and second shutter members and driving one of the first and second shutter members, as the other shutter member is driven,
- wherein when one of the first and second shutter members is driven, the connecting means moves the other shutter member in a direction contrary to the driven shutter member, and
- wherein the connecting mechanism comprises:
- a pinion installed rotatably within the body;
- a first linear rack toothed into the pinion to move one of the first and second shutter members when one of the first and second shutter members is driven;
- and
- a second linear rack toothed into the pinion in such a manner to be symmetrical to the first linear rack to thereby move other shutter member rather than the shutter member moved by the first linear rack.
A disc cartridge with gearing shutters including a body in which an opening is formed and an optical disc is received, comprising:
- first and second shutter members, formed on an exterior of the body, for opening and closing the opening;
- and
- a connecting mechanism for linking the first and second shutter members and driving one of the first and second shutter members, as the other shutter member is driven,
- wherein when one of the first and second shutter members is driven, the connecting means moves the other shutter member in a direction contrary to the driven shutter member, and
- wherein the connecting mechanism comprises:
- a belt member installed in an infinite track shape within the body and coupled in such a manner that the first and second shutter members are moved in a direction contrary to each other.
A disc cartridge with gearing shutters incluiding a body in which an opening is formed and an optical disc is received, comprising:
- first and second shutter members, formed on an exterior of the body, for opening and closing the opening;
- and
- a connecting mechanism for linking the first and second shutter members and driving one of the first and second shutter members, as the other shutter is driven,
- wherein the connecting mechanism moves the first and second shutter members in an overlapped state,and
- wherein a thickness of the second shutter member is thicker than that of the first shutter member in such a manner that the first shutter member can be inserted within the second shutter member.
A disc cartridge with gearing shutters including a body in which an opening is formed and an optical disc is received, comprising:
- first and second shutter members, formed on an exterior of the body, for opening and closing the opening;
- and
- a connecting mechanism for linking the first and second shutter members and driving one of the first and second shutter members, as the other shutter member is driven,
- wherein the connecting mechanism moves the first and second shutter members in an overlapped state, and
- wherein the connecting mechanism comprises:
- a guide hole defined within the body;
- a first slider inserted linear-movably into the guide hole and bound to the first shutter member;
- a second slider inserted linear-movably into the guide hole and bound to the second shutter member;
- a first spring member installed between one end of the first slider and the body to apply a restoring force to the first slider;
- and
- a second spring member installed one end of the second slider and the body to apply a restoring force to the second slider.
A disc driving apparatus, comprising:
- receiving means for receiving a small-size disc cartridge within which a small-size optical disc is received, the small-size disc cartridge including:
- first and second shutter members, formed on an exterior of a body, for opening and closing an opening;
- and
- connecting mechanism for linking the first and second shutter members and driving one of the first and second shutter members as the other shutter is driven;
- and
- driving means for driving the small-size disc cartridge.
