ABSTRACT An improved apparatus for recording and/or reproducing signals on a magnetic tape adapted to be wound on supply and take up reels of a tape cassette which are rotationally coupled with respective reel support members of the apparatus. The reel support members are selectively urge through a drive transmission to rotate in the direction for winding tape on the respective tape reels upon the manual actuation of a con- trol for causing operation of a reel drive. A shut off device is provided which is powered by the reel drive and is conditioned in response to the arresting of the rotation of the reel support members, for example when the tape is fully unwound from one of the reels, while operation of the reel drive con- tinues, in order to cause the control to halt operation of the drive by de-energization of an eletric motor thereof. The de-engergization is achieved by the release of a latch mechanism holding actuating members for the apparatus in an operative condition, by means of a latch release operating assembly having an oscillation member normally moving between two limited position during operation of the apparatus and driven by the drive means to an extreme position to release the latch upon arresting of the rotation of one of the reel support members. The device, in one embodiment, includes an assembly responsive to the actuating control of the apparatus for preventing the shut off device from halting operation of the drive when the controls of the apparatus are actuated to cause rewinding of tape onto the supply reel of the cassette during the play mode of the apparatus for the purpose of allowing signal review, so that the tape can be fully rewound during the review mode without halting the operation of the drive.
