Abstract
Abstract An image reading device for reading an image by a solid-state image reading elements (CCDs) being disposed at the image forming point of an optical unit which is integrated with at least an image forming lens, dichroic mirror for separating the color image into plural color components and unit construction parts such as a base, fixing plates, and lens barrel. The image reading elements are fixed to a lens holding member with an attaching plate by using adhesive. The attaching plate has a position adjusting mechanism.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
189 words
An image reading device for photoelectrically reading a color image light, comprising: (1) a lens; (2) a lens holding member for holding said lens; (3) an optical separation means for separating said color image light introduced by said lens into a plurality of color component lights wherein said optical separation means has an incident surface and a projection surface whereby said incident surface of said optical separation means is attached to one surface of said lens and said projection surface of said optical separation means is perpendicular to an optical axis thereof; (4) a plate member having two ends wherein a first end of said plate member is attached to said lens holding member with an adhesive and a second end of said plate member extends beyond said projection surface of said optical separating means wherein a thermal expansion coefficient of said plate member is substantially equal to that of said optical separation means; and (5) an image reading means for converting said plurality of color component lights to electric signals wherein said image reading means is attached to said second end of said plate member with an adhesive.
Claim 2
Dependent Claim
189 words
An image reading device for photoelectrically reading a color image light, comprising: (1) a lens; (2) a lens holding member for holding said lens; (3) an optical separation means for separating said color image light introduced by said lens into a plurality of color component lights wherein said optical separation means has an incident surface and a projection surface whereby said incident surface of said optical separation means is attached to one surface of said lens and said projection surface of said optical separation means is perpendicular to an optical axis thereof; (4) a plate member having two ends wherein a first end of said plate member is attached to said lens holding member with an adhesive and a second end of said plate member extends beyond said projection surface of said optical separating means wherein a thermal expansion coefficient of said plate member is substantially equal to that of said optical separation means; and (5) an image reading means for converting said plurality of color component lights to electric signals wherein said image reading means is attached to said second end of said plate member with an adhesive.
Claim 3
Dependent Claim
25 words
The image reading device of claim 1 further comprising a supporting member to support said lens thereon wherein said supporting member is of ceramic material.
Claim 4
Dependent Claim
15 words
The image reading device of claim 1, wherein said plate member is a ceramic material.
Claim 5
Dependent Claim
16 words
The image reading device of claim 1, wherein said plate member gas a position adjusting means.
Claim 6
Dependent Claim
26 words
The image reading device of claim 4 wherein said position adjusting means comprises two members whereby one of said members is movable relative to the other.
Claim 7
Dependent Claim
49 words
The image reading device of claim 5, wherein the first member of said two members has a elongated through hole therein and the second member has a guide pin so that the relative movement between both members is guided by both said elongated through hole and said guide pin.
Claim 8
Dependent Claim
15 words
The image reading device of claim 6, wherein said guide pin is a screw member.
Claim 9
Dependent Claim
47 words
The image reading device of claim 5, wherein the first member of said two members has a elongated groove therein and the second member has a guide pin so that the relative movement between both members is guided by both said elongated groove and said guide pin.
Claim 10
Dependent Claim
26 words
The image reading device of claim 5, wherein said two members are fixed with each other by using an adhesive after the position adjusting is completed.
