Abstract

Abstract A line photosensor comprising a plurality of sensor elements in at least one row on a substrate and a plurality of extract wiring electrodes extending from the respective sensor elements. The extract wiring electrodes are wired in an electrically isolated and laminated manner. The extract wiring electrodes are laminated such that they hold therebetween a laminated structure including a first insulating layer, an intermediate electrode layer formed on the first insulating layer, and a second insulating layer formed on the intermediate electrode layer.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 163 words
A line photosensor comprising: a plurality of sensor elements in at least one row on a substrate; a plurality of extract wiring electrodes extending from the respective sensor elements, said wiring electrodes being wired in an electrically isolated and laminated manner in which said extract wiring electrodes are laminated so that they hold therebetween a laminated structure including, in this order, a first insulating layer, an intermediate electrode layer formed on said first insulating layer, and a second insulating layer formed on said intermediate electrode layer; a first transistor for obtaining a photocurrent stored in one of said plurality of sensor elements, wherein said first transistor includes said first insulating layer and is connected to one of said extract wiring electrodes; and a second transistor for obtaining a photocurrent stored in another of said plurality of sensor elements, wherein said second transistor includes a third insulating layer formed on said second insulating layer and is connected to another of said extract wiring electrodes.
Claim 2
Dependent Claim 163 words
