Abstract
A disc cartridge capable of effectively preventing inadvertent falling out or detachment of a disc from a casing during handling thereof, to thereby ensure safety of the disc cartridge. A cover includes a disc receiving section and is slidably arranged between an upper casing member and a lower casing member, to thereby be outwardly drawn out through a disc takeout opening for taking out the disc from a casing. This permits the disc to be readily taken out from the casing by merely drawing out the cover from the casing.
Claims20
A disc cartridge comprising:
- a casing including an upper casing member and a lower casing member;
- a disc-shaped medium rotatable received in said casing;
- said casing being formed with openings including drive shaft insertion holes and head insertion holes;
- a shutter arranged on said casing so as to selectively close said openings;
- an elastic member arranged on said casing so as to urge said shutter in a direction in which said shutter is closed;
- said casing being formed with a disc takeout opening through which said disc-shaped medium is taken out from said casing;
- and
- a cover arranged in said casing so as to open and close said disc takeout opening;
- said cover including an outer wall portion which constitutes a part of a side wall of the cartridge for closing said disc takeout opening, a pair of side wall portions extending from opposite ends of said outer wall portion, and a disc receiving section extending between the outer wall portion and side wall portions of said cover, said disc receiving section including a disc support section adjacent the outer wall portion of said cover for supporting a lower surface of said disc-shaped medium and opposing disc holding portions extending from the side wall portions of said cover for engaging said disc-shaped medium, wherein said disc holding portions are spaced from said disc support section and said disc support section terminates at a position between the outer wall portion of said cover and said disc holding portions;
- and
- said cover being slidably arranged between said upper casing member and said lower casing member, to thereby be drawn out through said disc takeout opening from said casing, resulting in said disc-shaped medium being taken out from said casing, wherein said cover is provided with a bendable section so that it may be bent about said bendable section in relation to a direction in which said cover is slidably drawn out.
