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.
