Abstract
Abstract An improved photoelectric converting device in a layered structure comprising a base board, a plurality of divided electrodes, a photoelectric film and a common electrode is disclosed, wherein the improvement consists in that the width of a photoelectric current lead-out portion extending from each of the divided electrodes is dimensioned less than that of the body constituting the latter whereby an area of an intersected part formed by a combination of the divided electrodes and the common electrode, i.e., an area of each of light beam receiving sections becomes relatively constant among them, resulting in substantial reduction of an effect of unevenness or irregularity along the end part of the common electrode on image reproductivity of the respective light beam receiving sections.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
90 words
In a photoelectric converting device comprising an insulative base board, a plurality of divided electrodes, a photoelectric layer and a common electrode, said baseboard, divided electrodes, photoelectric layer and common electrode being placed one above another to form light beam receiving sections at overlapping areas between said divided electrodes and said common electrode, the improvement consisting in that the width of a photoelectric current lead-out portion extending from each of said light beam receiving sections of the divided electrodes is dimensioned less than the width of its respective divided electrode.
Claim 2
Dependent Claim
90 words
In a photoelectric converting device comprising an insulative base board, a plurality of divided electrodes, a photoelectric layer and a common electrode, said baseboard, divided electrodes, photoelectric layer and common electrode being placed one above another to form light beam receiving sections at overlapping areas between said divided electrodes and said common electrode, the improvement consisting in that the width of a photoelectric current lead-out portion extending from each of said light beam receiving sections of the divided electrodes is dimensioned less than the width of its respective divided electrode.
Claim 3
Dependent Claim
67 words
A photoelectric converting device as defined in claim 1, wherein the width of the photoelectric current lead-out portion extending from each of the divided electrodes is so dimensioned that an area of an overlapping part formed by that portion of the photoelectric current lead-out portion facing the common electrode is less than 10% of an area of the light beam receiving section of its respective divided electrode.
Claim 4
Dependent Claim
144 words
A photoelectric converting device comprising: (a) an insulative face; (b) a plurality of divided electrodes disposed on said insulative face; (c) a plurality of lead portions, each of said lead portions being electrically connected to one of said divided electrodes; (d) a photoelectric layer disposed over said divided electrodes and said lead portions; (e) a common electrode disposed over said photoelectric layer and in facing relationship to said divided electrodes and said lead portions, the areas of said common electrode facing said divided electrode and facing said lead portions defining areas of intersection, a first area of intersection between each of said divided electrodes and said common electrode being greater than a second area of intersection between each of said lead portions and said common electrode the width of each of said divided electrodes being greater than the width of its respective lead portion.
Claim 5
Dependent Claim
144 words
A photoelectric converting device comprising: (a) an insulative face; (b) a plurality of divided electrodes disposed on said insulative face; (c) a plurality of lead portions, each of said lead portions being electrically connected to one of said divided electrodes; (d) a photoelectric layer disposed over said divided electrodes and said lead portions; (e) a common electrode disposed over said photoelectric layer and in facing relationship to said divided electrodes and said lead portions, the areas of said common electrode facing said divided electrode and facing said lead portions defining areas of intersection, a first area of intersection between each of said divided electrodes and said common electrode being greater than a second area of intersection between each of said lead portions and said common electrode the width of each of said divided electrodes being greater than the width of its respective lead portion.
Claim 6
Dependent Claim
37 words
A photoelectric converting device as in claim 3, wherein said first area associated with each of said divided electrodes is at least ten times as great as its respective second area associated with its respective lead portion.
Claim 7
Dependent Claim
31 words
A photoelectric converting device as in claim 3, wherein any of said first areas is at least ten times greater than any of said second areas associated with said lead portion.
