Abstract
Abstract In an image sensor, a light receiving element unit is retained by a housing. The housing is produced with an injection plastic material through a monoblock molding. The light receiving element unit includes photoelectric converter, window, and electrode. Before the molding of the housing, the unit is installed at a predetermined position of a metallic mold. A surface of the unit is resultantly formed to be in a plane where a document conveying surface of the housing exists or to have a step relative to the document conveying surface.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
162 words
An image sensor comprising: light receiving element means comprising photoelectric converter means arranged in parallel with each other along a main scanning direction of said image sensor for receiving light reflected from an original document and for photoelectrically converting the light, window means disposed in association with said photoelectric converter means for allowing light to pass therethrough to the original document, and electrode means for obtaining a signal from the photoelectric converter means; light source means disposed on a side of a surface of said light receiving element means opposing to a surface on which said photoelectric converter means is fabricated for projecting a light onto the document via said window means; driver means for driving said photoelectric converter means and said light source means; and a housing for retaining said light receiving element means, said light source means, and said driver means, said housing being integral with said light receiving element means and including engaging means for retaining said driver means.
Claim 2
Dependent Claim
162 words
An image sensor comprising: light receiving element means comprising photoelectric converter means arranged in parallel with each other along a main scanning direction of said image sensor for receiving light reflected from an original document and for photoelectrically converting the light, window means disposed in association with said photoelectric converter means for allowing light to pass therethrough to the original document, and electrode means for obtaining a signal from the photoelectric converter means; light source means disposed on a side of a surface of said light receiving element means opposing to a surface on which said photoelectric converter means is fabricated for projecting a light onto the document via said window means; driver means for driving said photoelectric converter means and said light source means; and a housing for retaining said light receiving element means, said light source means, and said driver means, said housing being integral with said light receiving element means and including engaging means for retaining said driver means.
Claim 3
Dependent Claim
48 words
An image sensor as claimed in claim 1, wherein said housing is manufactured such that a surface thereof disposed on a side of said light receiving element means where said photoelectric converter means is formed is in a plane that includes a surface of said photoelectric converter means.
Claim 4
Dependent Claim
62 words
An image sensor as claimed in claim 1, wherein said housing is manufactured such that a surface thereof disposed on a side of said light receiving element means where said photoelectric converter means is formed is manufactured relative to the surface of said photoelectric converter means, the surface of said housing being gradually lowered along a direction of passage of the document.
Claim 5
Dependent Claim
26 words
An image sensor as claimed in claim 1, wherein said window means is disposed such that a periphery thereof is enclosed by said photoelectric converter means.
Claim 6
Dependent Claim
34 words
An image sensor as claimed in claim 1, wherein said electrode means includes a common electrode disposed on a side of said photoelectric converter means and a separate electrode arranged on another side thereof.
