Abstract
Abstract A contact image sensor for use as an image readout unit in a facsimile machine or the like equipment, wherein, for the purpose of realizing reduction of its cost and improvement of its assembling performance, a rod lens array and a photoelectric converter element array are supported by a first supporting member while a light source is supported by a second supporting member separate from the first supporting member.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
93 words
A contact image sensor comprising: a light source; a rod lens array; a photoelectric converter element array; a first supporting member for supporting said rod lens array and said photoelectric converter element array, the first supporting member being formed from a synthetic resin and having a surface that has been treated to lower the light reflection factor of the surface; and a second supporting member for supporting said light source, said second supporting member being separate from said first supporting member and being made of a material having a good heat radiating property.
Claim 2
Dependent Claim
93 words
A contact image sensor comprising: a light source; a rod lens array; a photoelectric converter element array; a first supporting member for supporting said rod lens array and said photoelectric converter element array, the first supporting member being formed from a synthetic resin and having a surface that has been treated to lower the light reflection factor of the surface; and a second supporting member for supporting said light source, said second supporting member being separate from said first supporting member and being made of a material having a good heat radiating property.
