Abstract: PURPOSE:To prevent the breakdown of an image pickup element caused by the difference of the supply timing of power source and every drive signal to a camera head part by stopping the operation of a power circuit in a main body, and stopping the supply of the power source and every drive signal to a camera head part side when a camera cable is disengaged. CONSTITUTION:When the connector of the camera cable is disengaged from the receptacle 15 of the main body 2, a DC bias comes not to be supplied to the camera head part side, and the light emission diode 27 of a photocoupler 26 to detect this supply current stops light emission, and a detection signal to be impressed to the input terminal of a power control guide circuit 28 becomes an H-level. Then, in the logic circuit 28, a control output signal is switched to the H-level, and in the power circuit 14, the generation of power output is stopped on receiving the inversion of the control output signal. Accordingly, even if the connector of the camera cable is connected again to the receptacle 15 of the main body 2, the drive pulse and the DC bias are not supplied to the camera head part side. Thus, the breakdown of the image pickup element due to the timing difference of the signals to be impressed can be prevented.
