Abstract
Abstract This electronic endoscope is provided with a flexible insertable part formed to be small in the diameter. A plurality of components provided in parallel are included within the insertable part tip. A second largest component which has a contour smaller than the contour of a solid state imaging device which is one of the above mentioned components but larger than those of the other components and in which at least a part of the contour overlaps on an imaginary circle having the smallest diameter including the contour of the above mentioned solid state imaging device with the center of the solid state imaging device as a center is included. An objective system having an optical axis coinciding with the center of the above mentioned image area is included.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
149 words
An electronic endoscope comprising: a flexible insertable part formed to be small in the diameter; a plurality of components provided in parallel within a tip of said insertable part; a solid state imaging device which is one of said components and in which a solid state imaging chip having an image area provided at right angles with the lengthwise direction of the insertable part is secured on a base; a second largest component which has a contour smaller than the contour of said solid state imaging device but larger than the other components and in which at least a part of the contour overlaps on an imaginary circle having the smallest diameter including the contour of said solid state imaging device with the center of said image area as a center; and an objective system provided to have the optical axis coincide with the center of said image area.
Claim 2
Dependent Claim
149 words
An electronic endoscope comprising: a flexible insertable part formed to be small in the diameter; a plurality of components provided in parallel within a tip of said insertable part; a solid state imaging device which is one of said components and in which a solid state imaging chip having an image area provided at right angles with the lengthwise direction of the insertable part is secured on a base; a second largest component which has a contour smaller than the contour of said solid state imaging device but larger than the other components and in which at least a part of the contour overlaps on an imaginary circle having the smallest diameter including the contour of said solid state imaging device with the center of said image area as a center; and an objective system provided to have the optical axis coincide with the center of said image area.
