Abstract
Abstract A method of adjusting the position of a solid-state scanning element and mounting the same, in a manuscript reading optical block included in a manuscript reading part of a solid-state electronic scanning system is disclosed in which the position of the solid-state scanning element is adjusted by handling the solid-state scanning element itself in a state that an adjustment pattern forming an optical standard and a lens support forming a positional standard of a device are set to an adjustment jig, so that the highest optical sensitivity is obtained, and in which a wiring board is fixed to the lens support in such a manner as using the position of a pin of the solid-state scanning element as a guide, while maintaining the solid-state scanning element in the above-mentioned adjusted state, and then the pin of the solid-state scanning element is fixed to the wiring board using a melt made of solder or the like to make an electrical connection therebetween.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
151 words
A method of adjusting the position of a solid-state scanning element and mounting the same, in a manuscript reading optical block included in a manuscript reading part of a solid-state electronic scanning system, comprising the steps of: adjusting the position of said solid-state scanning element so to provide an output therefrom of the highest optical sensitivity for an adjustment pattern forming an optical standard, said adjustment pattern and a lens support forming a positional standard being disposed with respect to an adjustment jig for said solid-state scanning element; fixing a wiring board to said lens support utilizing the position of a pin of said solid-state scanning element as a guide, while maintaining said solid-state scanning element in the adjusted position; and fixing said pin of said solid-state scanning element to said wiring board using a melt to make an electrical connection therebetween, said melt being made of solder or the like.
Claim 2
Independent Claim
151 words
A method of adjusting the position of a solid-state scanning element and mounting the same, in a manuscript reading optical block included in a manuscript reading part of a solid-state electronic scanning system, comprising the steps of: adjusting the position of said solid-state scanning element so to provide an output therefrom of the highest optical sensitivity for an adjustment pattern forming an optical standard, said adjustment pattern and a lens support forming a positional standard being disposed with respect to an adjustment jig for said solid-state scanning element; fixing a wiring board to said lens support utilizing the position of a pin of said solid-state scanning element as a guide, while maintaining said solid-state scanning element in the adjusted position; and fixing said pin of said solid-state scanning element to said wiring board using a melt to make an electrical connection therebetween, said melt being made of solder or the like.
Claim 3
Dependent Claim
42 words
A method according to claim 1, further comprising the steps of providing a through hole in said wiring board with a clearance with respect to said pin to allow the inclination of said solid-state scanning element with respect to said wiring board.
Claim 4
Independent Claim
250 words
A method of adjusting the position of a solid-state scanning element and mounting the same, in a manuscript reading optical block included in a manuscript reading part of a solid-state electronic scanning system, comprising the steps of: setting an adjustment pattern and a lens support relative to an adjustment jig, said adjustment pattern forming an optical standard, said lens support including therein a lens, said lens support forming a positional standard of a device, a perforation being provided in said lens support; inserting a chucking arm of said adjustment jig into said perforation of said lens support to hold said solid-state scanning element by said chucking arm; reading said adjustment pattern by said solid-state scanning element through said lens when said solid-state scanning element is held by said chucking arm, said adjustment pattern being set on a read-out line; adjusting the position of said solid-state scanning element by said adjustment jig so that an output from said solid-state scanning element is obtained at the highest sensitivity; setting a wiring board so that a pin provided on said solid-state scanning element is inserted into a through hole provided in said wiring board, while maintaining said solid-state scanning element in an adjusted state; fixing said wiring board to said lens support; and fixing said pin of said solid-state scanning element to said through hole of said wiring board using a melt to make an electrical connection between said pin and said wiring board, said melt being made of solder or the like.
Claim 5
Independent Claim
250 words
A method of adjusting the position of a solid-state scanning element and mounting the same, in a manuscript reading optical block included in a manuscript reading part of a solid-state electronic scanning system, comprising the steps of: setting an adjustment pattern and a lens support relative to an adjustment jig, said adjustment pattern forming an optical standard, said lens support including therein a lens, said lens support forming a positional standard of a device, a perforation being provided in said lens support; inserting a chucking arm of said adjustment jig into said perforation of said lens support to hold said solid-state scanning element by said chucking arm; reading said adjustment pattern by said solid-state scanning element through said lens when said solid-state scanning element is held by said chucking arm, said adjustment pattern being set on a read-out line; adjusting the position of said solid-state scanning element by said adjustment jig so that an output from said solid-state scanning element is obtained at the highest sensitivity; setting a wiring board so that a pin provided on said solid-state scanning element is inserted into a through hole provided in said wiring board, while maintaining said solid-state scanning element in an adjusted state; fixing said wiring board to said lens support; and fixing said pin of said solid-state scanning element to said through hole of said wiring board using a melt to make an electrical connection between said pin and said wiring board, said melt being made of solder or the like.
Claim 6
Dependent Claim
36 words
A method according to claim 3, wherein said through hole provided in said wiring board has a clearance to said pin to allow the inclination of said solid-state scanning element with respect to said wiring board.
Claim 7
Dependent Claim
42 words
A method according to claim 1 or 3, further comprising the step of interposing a spacer between said lens support and said wiring board to compensate for a positional shift of said solid-state scanning element in the direction of an optical axis.
Claim 8
Dependent Claim
39 words
A method according to claim 1, wherein the step of adjusting the position of said solid-state scanning element includes reading the adjustment pattern by said solid-state scanning element along an optical path delimited at least by said lens support.
Claim 9
Dependent Claim
29 words
A method according to claim 6, said lens support supports a lens and the reading of the adjustment pattern is effected along the optical path having said lens therein.
