ABSTRACT:
A DVI circuit for generating a digital video signal in accordance with a display standard of a personal computer, etc. is provided for a processor device to which an electronic endoscope is connected. On the output side of the DVI circuit, a high vision system converter which is an adapter unit is connected as arbitrarily attached and removed using a connector. In the processor device, when the fixed state of a fixing screw is detected by a detection switch SW1, and it is determined that the power supply line connected using a connector to the high vision system converter is in the energized state, a live line processing circuit activates a signal line of the connector. Thus, the adapter unit can be easily attached and removed without turning off the processor device.
