    • A disc cartridge is constructed so that disc access to a recording medium enclosed within the disc cartridge via an opening in the cartridge case is restricted by a disc tray and a shutter member disposed inside the cartridge case. The shutter member is rotatably attached to one of the disc tray and the cartridge case, and detachment of the shutter member is restricted at least in a range of rotation of the shutter member between a position where the shutter member covers part of the opening and a position where the shutter member has been withdrawn from the opening. Attachment of the shutter member is carried out without crimping.

    • A cleaning cassette capable of accomplishing a safe and positive cleaning operation while ensuring smooth and stable running of a cleaning tape. The cleaning cassette includes a tape passing mechanism arranged at a front portion of a casing for ensuring satisfactory traveling of the cleaning tape while reducing contact between the cleaning tape and a head cylinder of a cassette tape deck. The mechanism includes a pair of rollers through which the cleaning tape is passed, a support member for supporting each of the rollers at each of its respective ends such that each roller can rotate and a pair of partitions provided between insertion recesses of the casing. The support member on which the rollers are supported in a manner to be laterally spaced from each other is loosely fitted between the partitions so as to reciprocatively movable in a longitudinal direction of the casing or protrude from the casing and retract into the casing when loading and unloading of the cassette with respect to the cassette tape deck is carried out, respectively.
    • 一种能够在确保清洁带的平稳和稳定运行的同时实现安全和正面清洁操作的清洁盒。 清洁盒包括布置在壳体的前部的带通机构,用于确保清洁带的令人满意的行进,同时减少清洁带与盒式磁带的头缸之间的接触。 该机构包括清洁带通过的一对辊,支撑构件,用于支撑每个辊各自的端部中的每个辊,使得每个辊可旋转,并且一对隔壁设置在壳体的插入凹部之间。 其上以相互横向隔开的方式支撑滚子的支撑构件松散地装配在隔板之间,以在壳体的纵向方向上往复运动,或者在装载时从壳体突出并缩回到壳体中,并且 分别执行盒式磁带相对于盒式磁带机的卸载。
