Endoscope system with means for detecting auxiliary apparatuses
First Claim
1. An endoscope system comprising:
- an endoscope including a light guide for transmitting an illumination light, an image guide for transmitting light reflected by a region of interest on which the illumination light from the light guide is projected, and a viewing section for viewing an image of the region of interest transmitted through the image guide;
a light source for supplying illumination light to said light guide of said endoscope;
an auxiliary apparatus capable of being removably attached to said viewing section of said endoscope; and
detecting means for detecting the attachment of an auxiliary apparatus and the kind of said auxiliary apparatus attached to said viewing section of said endoscope and including means for setting the intensity of light fed into said light guide of said endoscope in accordance with the detected attachment of an auxiliary apparatus and as a function of the detected kind of said attached auxiliary apparatus.

Abstract
An endoscope system comprises an endoscope, a light source unit, and an auxiliary apparatus such as a camera unit or a dual viewing optical unit. The light source unit includes a discriminating circuit which discriminates the kind of the auxiliary apparatus when the auxiliary apparatus is attached to a viewing section of the endoscope. The discriminating circuit causes a solenoid energizing circuit to drive a solenoid in accordance with the kind of the auxiliary apparatus, thereby moving a stop to a predetermined position. In consequence, illumination light of a given intensity corresponding to the kind of attached auxiliary apparatus is led from a light source into a light guide of the endoscope. Thus, an image can always be observed with suitable brightness through the auxiliary apparatus or the viewing section of the endoscope without regard to the attachment of the auxiliary apparatus, as well as to the kind thereof.
