ーオフ装置。[Claims for Utility Model Registration] (1) In a cassette VTR, a means for supplying a rewind end signal generated at the end of a tape to a power-off control switch is connected to the power-off control switch to latch the rewind end signal. The latch circuit is a power source for a cassette VTR comprising means for supplying the rewind signal to the circuit, a means for maintaining an output signal based on the rewind end signal, and a means for controlling a control terminal of a power supply circuit of the cassette VTR using the output signal. Auto power off device that shuts off the power. (2) The auto power-off device according to claim (1), wherein the power-off control switch comprises an analog switch. (3) The automatic power-off device according to claim 1 or 2, further comprising means for supplying a delayed rewind end signal, which is obtained by delaying the rewind end signal by a predetermined time, to the power off control switch. (4) The auto power-off device according to claim (1) or (3), wherein the means for making the power-off control switch conductive comprises a control signal generated based on the delayed rewind end signal.
