Abstract: An information reproduction apparatus is provided comprising: supporting means for supporting a recording medium; a drive source for moving the recording medium between an initial insertion position and a reproduction position by driving said supporting means; transmission means incorporating a transmission element for transmitting the driving force of said drive source to said supporting means; characterised by retraction means operable to disengage said transmission element from said transmission means; and motion means operable to drive the recording medium from the reproduction position to the initial insertion position when said transmission element is disengaged, whereby said recording medium may be removed in the event of failure of said drive source.

Abstract: An information reproduction apparatus in provided with supporting means for supporting a recording medium. A drive source, for moving the recording medium, is located between an initial insertion position and a reproduction position by driving said supporting means. Transmission means is included for transmitting the driving force of said drive source to said supporting means plus retraction means, operable to force a transmission element to retract from said transmission means. The transmission element is a part of said transmission means. Motion means operable to force the recording medium to move from the reproduction position to the initial insertion position under the condition that said transmission element is not engaged in said transmission means, so that in forcibly moving said supporting means, when the drive is out of operation, said supporting means are released from the drive force by means of said retraction means, thereby freeing the supporting means from the resistance force of the drive force. However, under normal operation, the said transmission element is returned to the said driving force transmitting path, thereby stopping inconvenience to the operation.
