Abstract: A recording-medium transfer device having a anti-rattle construction is provided. A transfer roller 6 of the recording-medium transfer device is arranged above a chassis 5 to be perpendicular to a direction X of transferring recording medium. The transfer roller 6 has a structure in which a shaft is inserted in rolling member made of a material having flexibility. Projecting portions 13 and 14 are formed on the chassis 5 to oppose to both ends of the rolling member. In both ends of the rolling member, clearances are respectively formed to permit the deformation produced by its abutment with the projecting portions 13 and 14. In the process for inserting the disc, the projecting portions 13 and 14 are moved away from the transfer roller 6. Upon receiving a driving force from a driving motor 7 and gears 8 to 11, the rolling member of the transfer roller 6 is rotated keeping in contact with the disc so as to transfer the disc toward a clamping position.

Abstract: A main chassis is provided to mount a system for reproducing a large diameter disc and a small diameter disc, a pair of disc carrying rollers is mounted on the main chassis for carrying an inserted disc to the system, and a large diameter disc detector arm is provided to be pivoted by a large diameter disc carried by the disc carrying rollers so that the large diameter disc is clamped. An adapter is detachably mounted on the main chassis. A pair of centering arms are mounted on the adapter for centering a small diameter disc carried by the disc carrying rollers, and a small diameter disc detector arm mounted on the adapter for operating the large diameter disc detector arm for clamping the carried small diameter disc.

Abstract: A supporting mechanism is provided to be moved between a disc insertion opening and a disc storing device, and a driving roller is rotatably mounted on the supporting mechanism for carrying a disc inserted in the opening toward the disc storing device. The supporting mechanism is moved between the opening and the disc storing device, and the driving roller is driven for carrying the disc from the opening to the disc storing device.

Abstract: A supporting means is provided to be moved between a disc insertion opening and a disc storing device, and a driving roller is rotatably mounted on the supporting means for carrying a disc inserted in the opening toward the disc storing device. The supporting means is moved between the opening and the disc storing means, and the driving roller is driven for carrying the disc from the opening to the disc storing device.
