ABSTRACT:
A tape rewinding apparatus which can be lifted in response to a sudden relaxion of the transmission belt upon the tape running to the end and the winding spindle is hindered from rotating. The change of tension is sensed by a small pulley which is biased firmly against the transmission belt and driven thereby. A controlling member having a fixed end capable of retaining a catch member is disposed on the compartment lid, and having a free end to which the small pulley is mounted. By such arrangement, at the moment the tension relaxes, the controlling member will disengage the catch member.
