摘要： The present invention is related to a disc cartridge in which an optical disc, an inner shell and shutter members are housed in a main cartridge body unit, formed by abutting and combining upper and lower shells and in which the inner shell is run in rotation to cause the shutter members to open or close an aperture provided in the main cartridge body unit. The inner shell is formed by a resin molding portion comprised of a first molded portion for forming the inner shell and a second molded portion connected to the first molded portion. The second molded portion is provided at a position forming the aperture in the inner shell and is connected to the first molded portion through a flanged thin-walled section. The inner shell is formed by severing the second molded portion and the flanged thin-walled section.

摘要： A method for producing an inner shell used for a disc cartridge in which an optical disc, an inner shell and shutter members are housed in a main cartridge body unit. The inner shell provided in the main cartridge body unit includes a first molded portion, provided with an aperture, a second molded portion having a resin injection port and molded at a position where the aperture is formed, and a flanged thin-walled section connecting the first and second molded portions to each other. The method includes the steps of injecting molten resin into a cavity defined by a fixed metal die and a movable metal die for molding the first molded portion, the second molded portion, and the flanged thin-walled section, and severing the flanged thin-walled section by a punch provided to the movable metal die before the molten resin injected into the cavity is cooled and solidified.

摘要： A disk cartridge in which a pair of shutter members can be opened and closed smoothly and reliably, and a dust-proof property and an airtightness of a large opening portion can be increased by reducing a space between a pair of shutter members and a cartridge housing as much as possible. The disk cartridge comprises a cartridge housing in which a disk compartment is formed-between an upper shell and a middle shell by overlapping the upper shell, the middle shell and the lower shell and the middle shell is supported by the upper shell and the lower shell so as to become freely rotatable, an optical disk rotatably stored within the disk compartment and a pair of shutter members attached to the middle shell in such a manner that they can be moved in the plane direction on the same plane. A shutter opening and closing mechanism for opening and closing opening portions by moving the pair of shutter members based rotation of the middle shell.

摘要： In a disk cartridge including a cartridge housing (22), an optical disk (21) and a shutter mechanism (28), a butt portion (71a) of at least one shutter member of a pair of shutter members (50), (51) includes a recess portion (75) into which the other butt portion (72a) is inserted. A space produced between the shutter members (50), (51) of the shutter mechanism (28) comprising the first shutter member (50) and the second shutter member (51) can be reduced as much as possible. The disk cartridge is made dustproof by suppressing dusts or the like from entering a disk compartment in which a disk-like recording medium is accommodated.
