Guide structure for electronic endoscope systems
First Claim
1. A connector guide structure for electronic endoscope systems comprising:
- a main unit of an electronic endoscope system;
a connector disposed on an electronic endoscope;
a connector guide which is disposed for connecting said connector on the electronic endoscope to said main unit and electrically insulated from a console of the main unit;
a noise eliminating capacitor disposed between said connector guide and said console of the main unit; and
wherein an interval within a range from 4 mm to 20 mm is reserved between said connector guide and said console of the main unit for connecting said noise eliminating capacitor.

Abstract
A connector guide structure for electronic endoscope systems capable of efficiently eliminating high-frequency noises which are allowed by a connector guide functioning as an antenna to mix by way of sheath members and a console. The connector guide structure comprises a connector guide for connecting a connector disposed on an electronic endoscope to a main unit, and noise eliminating capacitors are connected between the connector guide and a console of the main unit. A capacitor for eliminating noises produced by a radio knife and a plurality of capacitors for eliminating noises produced by clock-frequency signals are used as the capacitors. Feet of the capacitors are directly connected within an interval of 4 mm to 20 mm which is reserved between the connector guide and the console. Accordingly, the connector guide structure is capable of favorably eliminating not only the noises produced by the radio knife but also the noises produced by providing clock-frequency signals.
