Abstract

Abstract A tape handler is provided having a drive coupling mechanism, a part thereof being axially translatable in response to an end-oftape condition. The handler includes a pivotally mounted carrier forming a pocket to receive and retain a tape cassette, the carrier being releasably secured to the body of the handler, the translatable part having the function of initiating both the release of the cassette and of the carrier, the latter resulting in a separation of the carrier from the handler body sufficient to uncouple tape drive.
