    • A disk cartridge does not require a plate supporter for holding a chucking plate on an upper shell. In this disk cartridge, a chucking plate for chucking a disk on a turntable, driven by a spindle motor, is placed on the middle of the disk so the chucking plate is vertically movable together with the disk. The disk cartridge further includes a peripheral cylindrical rib which is not in contact with the disk and is configured to limit movement of the chucking plate in the direction of its diameter while permitting the vertical movement of the chucking plate. The peripheral cylindrical rib is molded integral with the lower surface of the upper shell.
    • 磁盘盒不需要用于将夹板固定在上壳上的板支撑件。 在该磁盘盒中,将用于将盘驱动在由主轴电动机驱动的转台上的盘的夹板放置在盘的中间,使得夹盘与盘一起可垂直移动。 盘盒还包括不与盘接触的周边圆柱形肋,并且构造成限制夹盘在其直径方向上的移动,同时允许夹盘的垂直运动。 周边圆柱形肋与上壳的下表面成一体模制。

    • 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.
    • 一种用于制造用于盘盒的内壳的方法,其中光盘,内壳和挡板部件容纳在主盒体单元中。 设置在主盒体单元中的内壳包括设置有孔的第一模制部分,具有树脂注入口的第二模制部分,并且在形成该孔的位置处模制,以及连接该壳体的凸缘薄壁部分 第一和第二模制部分彼此。 该方法包括以下步骤:将熔融树脂注入到由固定金属模具和用于模制第一模制部分,第二模制部分和带凸缘的薄壁部分的可移动金属模具限定的空腔中,并且将法兰薄壁 在注入到空腔中的熔融树脂被冷却和固化之前通过设置到可移动金属模具的冲头的截面。

    • 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.
