Abstract
A shielding structure of an electronic endoscope apparatus which can sufficiently remove noise even when an electric cautery is used. A signal transmission cable which connects a charge coupled device disposed at the end portion of an electronic endoscope to a processor unit is electrically shielded by a double shield composed by an inner shield and an outer shield. The inner shield is connected to the ground in a light source connector and the outer shield is connected to the frame ground of the processor unit through a capacitor. The outer shield is further connected to a shielding member provided around the charge coupled device and a patient ground to which an electrode piece of an electric cautery is connected. Noise is greatly removed, so that the picture quality is improved.
