のをやめる。FIG. 1 shows one means for implementing the present invention. The TV 1 is supplied with power from the AC outlet 5 of the VTR 2 by the power cord 3c. The current flowing through the power cord is larger when the TV is in the operating state than when the TV is not in the operating state. Therefore, the current detection circuit 6 in the VTR 2 detects the difference between the currents, thereby confirming that the TV is not in the operating state. Detect. At this time, if the VTR 2 is not performing any recording / playback / fast forward / rewind operation for a certain period of time,
The power supply 4 is controlled by the microcomputer 8 and the supply of power to each circuit 7 inside the VTR is stopped so that the power supply of the VTR is turned off.

ＶＴＲ２を電源切りの状態にする。FIG. 2 shows another means for carrying out the present invention. The TV1 is connected to the VTR2 with the video signal connection cable 3d of the TV output VTR input. When the TV1 is not in operation, the video signal from the TV1 is not input to the VTR2, and the video signal detection circuit 9 inside the VTR2 detects that the TV is not in operation. At this time, if the VTR 2 is not performing any operation of recording / playback / fast forward / rewind for a certain period of time, the microcomputer 8 controls the power source 4,
The VTR2 is turned off.
