Abstract
Abstract This electronic endoscope has an insertable part having an observing window on the side of a tip part extended forward of the insertable part. The solid state imaging device is to receive an entering light from the above mentioned observing window and is arranged so as to intersect substantially at right angles with the axial direction of the above mentioned insertable part. Contents are arranged on the opposite observing window side of this solid state imaging device. This solid state imaging device is provided with wire bonding parts on the side different from the side on which the above mentioned contents are arranged.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
160 words
An electronic endoscope having a solid state imaging device, comprising: an insertable part extended from an operating part and having an observing window on the side of a tip part; a solid state imaging device for receiving an incident light from said observing window and arranged so as to intersect substantially at right angles with the axial direction of said insertable part, wherein said solid state imaging device is formed of a substrate and a solid state imaging chip secured to said substrate; a plurality of internal members having signal line means electrically connected to said substrate, wherein one of said plurality of internal members is arranged of an opposite observing window side of said solid state imaging chip in a plane including said solid state imaging device; and a wire bond part which electrically connects said solid state imaging chip with said substrate and is provided on a side different from the side of said plurality of internal members.
Claim 2
Dependent Claim
160 words
An electronic endoscope having a solid state imaging device, comprising: an insertable part extended from an operating part and having an observing window on the side of a tip part; a solid state imaging device for receiving an incident light from said observing window and arranged so as to intersect substantially at right angles with the axial direction of said insertable part, wherein said solid state imaging device is formed of a substrate and a solid state imaging chip secured to said substrate; a plurality of internal members having signal line means electrically connected to said substrate, wherein one of said plurality of internal members is arranged of an opposite observing window side of said solid state imaging chip in a plane including said solid state imaging device; and a wire bond part which electrically connects said solid state imaging chip with said substrate and is provided on a side different from the side of said plurality of internal members.
