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 urged through a drive transmission to rotate in the direction for winding tape on the respective tape reels upon the manual actuation of a control 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 continues, in order to cause the control to halt operation of the drive by de-energization of an electric motor thereof. The de-energization 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 oscillating member normally moving between two limited positions 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 controls 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 allowing signal review, so that the tape can be fully rewound during the review mode without halting the operation of the drive.

An apparatus operable in a plurality of modes, including play, stop, and rewind modes, for recording and/or reproducing signals on a magnetic tape extending between first and second reels to which the ends of the tape are secured and on which the tape is wound, said apparatus comprising: first and second rotatable reel support members for rotational coupling with the first and second reels, respectively; drive means; drive control means to effect operation of said drive means to operate said apparatus in any of said modes; transmission means connected to said drive means and comprising a first member driven in one direction by said drive means and further comprising means to couple said first member selectively to either of said reel support members for selectively driving the selected reel support member to rotate in the direction for winding tape on the reel respectively coupled therewith in response to operation of said drive means and permitting continued operation of said drive means when rotation of said reel support members is arrested upon the full unwinding of the tape from the other of said reels, said transmission means including means responsive to the drive control means for rotating one of said reel support members in said play mode and for interrupting the play mode and rewinding tape onto the reel coupled with the other of said reel support members, thereby to permit review of signals on tape wound on the reel coupled with said one reel support member during said play mode; shutoff means coupled to said first member of said transmission means to be powered by said drive means and having a first condition for causing said drive control means to halt the operation of said drive means and a second condition in which said drive means is unaffected by said shutoff means; and shutoff control means connected with one of said reel support members for disposing said shutoff means in said second condition in response to rotation of said one reel support member and for disposing said shutoff means in said first condition in response to arresting of the rotation of said reel support members during continued operation of said drive means; and means responsive to said drive control means for preventing said shutoff control means from disposing the shutoff means in said first operative condition when said drive control means is actuated to cause said transmission means to rewind tape onto the reel coupled with the other of said reel support members during the play mode to permit signal review, whereby said tape can be fully rewound during the play mode without halting the operation of said drive means.
