Abstract

PURPOSE:To ensure the safety and to elongate the life of a camera, by stopping a power supply of camera, if the power supply of a monitor television is interrupted at the use of the camera. CONSTITUTION:A switching circuit 5 for the power supply of a camera is supplied with an output H of a recording signal switching circuit 7 and an output F of a monitor signal switching circuit 8. At the reception of camera channel, a transistor TRQ11 of the circuit 8 is turned on, TRs Q4, Q5 are also turned on to supply power to the camera. Further, even when the camera channel is received only a TRQ9 turns on, since a monitor television is at onstate, the TRs Q4, Q5 are turned off and the power is not applied to the camera at monitor-off. Further, when a VTR is at recording state in the camera channel received and with monitor-off state, on, and even if the power switch is at off-state, a recording signal (d) is switched to a camera signal (b) and the power is supplied to the camera at the same time because a TRQ3 is turned on and the TRs Q4, Q5 are turned on.
