ELECTRONIC ENDOSCOPE
First Claim
1. An electronic endoscope comprising:
- a distal end portion of an insertion portion which incorporates electronic components;
a metal frame which is disposed at the distal end portion and holds an observation window;
an earth member which is connected to a patient-side ground of an external device; and
a static-protective member which is disposed in the distal end portion to have a predetermined clearance from the metal frame and is electrically connected to the earth member to let static electricity applied to the distal end portion flow to the earth member.

Abstract
An electronic endoscope includes a distal end portion of an insertion portion which incorporates electronic components, a metal frame which holds an observation window, an earth member which is connected to a patient-side ground of an external device, and a static-protective member which is disposed in the distal end portion to have a predetermined clearance from the metal frame and is electrically connected to the earth member to let static electricity E applied to the distal end portion flow to the earth member. With the configuration, the electronic endoscope prevents occurrence of trouble, a fault, and the like in an electronic component incorporated in the distal end portion due to applied static electricity.
