Electronic endoscope in which static-protective member is provided in distal end portion of insertion portion
First Claim
1. An electronic endoscope in which a static-protective member is provided in a distal end portion of an insertion portion, the electronic endoscope comprising:
- the distal end portion of the 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
the 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, whereinthe static-protective member is a metal plate body having a conductive portion in a shape of a pointed end which easily discharges the static electricity.

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 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.
