摘要： A disc cartridge capable of preventing a recording surface section of a disc from being contacted by a casing and placing the disc at a proper position in the casing without damaging and polluting, to thereby ensure the safe and smooth operation of the disc in the casing. The disc cartridge includes a pair of disc receivers each of which is formed therein with a recess for receiving a peripheral portion of the disc. The recess has an end surface contacting an outer periphery of the disc, which is formed into a substantially sideways V-shape of which an apex is positioned at substantially a center of the end surface to position the outer periphery of the disc at the center of the end surface.

摘要： A disc cartridge capable of effectively preventing a shutter from being opened even when any unexpected shock is suddenly applied to the disc cartridge during non-use of the disc cartridge. The disc cartridge includes a connection mechanism for operatively connecting to disc receivers, actuators for releasably locking the shutter. The connection mechanism is constituted by a guide groove provided in the actuator and formed into a substantially sideways U-shape, and a guide pin provided on the disc receiver and movably fitter within the guide groove. The guide pin is spaced from two surfaces of the guide groove opposite to the guide pin, in the actuating direction of the actuator. Also, the disc cartridge includes a substantially V-shaped spring for constantly positioning the guide pin within the guide groove and forcing the disc receiver to return to its original position to keep the guide pin apart from the opposite surfaces of the guide groove. Thus, even when the disc receiver is moved due to any shock applied to the disc cartridge during non-use, it is effectively prevented from abutting against the actuator, resulting in failure to actuate the actuator and preventing actuation of the shutter during non-use.

摘要翻译： 即使在不使用光盘盒期间突然将任何意外的电击施加到光盘盒时，也能够有效地防止快门被打开。 盘盒包括用于可操作地连接到盘接收器的连接机构，用于可释放地锁定快门的致动器。 连接机构由设置在致动器中的形成为大致侧面U形的引导槽和设置在盘式接收器上并可移动地装配在引导槽内的引导件构成。 引导销在致动器的致动方向上与引导销相对的引导槽的两个表面间隔开。 此外，盘盒包括大致V形的弹簧，用于将引导销恒定地定位在引导槽内，并迫使盘片接收器返回到其原始位置，以使引导销与引导槽的相对表面分开。 因此，即使当在不使用期间由于施加到盘盒的任何冲击而使碟片接收器移动时，也可以有效地防止其与致动器抵靠，从而导致致动器不能致动并且在不使用时防止快门致动 。

摘要： A disc cartridge capable for ensuring smooth movement of a disc receiver for a long period of time with high reliability. The disc cartridge includes a pivot pin on which a disc receiver is supported so as to be pivotally movable about the pivot pin and which is mounted on a lower inner surface of a casing to inwardly project therefrom. The pivot pin cooperates with a bearing mounted on an upper inner surface of the casing to constantly form a gap in a thickness direction of the casing in the casing which has a distance sufficient to ensure smooth pivotal movement of the disc receiver about the pivot pin in the casing.

摘要： A disc cartridge capable of preventing a recording surface section of a disc from being contacted with an inner surface of a casing so that the disc may be free from any damage. The disc cartridge includes steps or sheet-like members provided on the inner surface of the casing in a manner to be inwardly projected from the inner surface. The steps or sheet-like members are positioned so as to be engaged with a non-recording surface section of the disc to support the disc thereon, so that a clearance may be defined between the recording surface section of the disc and the inner surface of the casing.
