Abstract:
An image sensor using three-color, e.g., R, G, and B light-emitting elements assures a period in which all the three colors are turned on and periods in each of which one light-emitting element is turned off during a scan period per pixel, and integrates and measures amounts of light of the respective periods. An amount of light based on the OFF light-emitting element is calculated based on a difference between the amounts of light during the full light-ON period and each light-OFF period to define an amount of light of the light-emitting element, and light intensity information corresponding to each light-emitting element is obtained based on a total amount of light during the entire scan period per pixel, and the amount of light of each light-emitting element.
Abstract:
In an image reading apparatus incorporating a CIS unit warped by heat shrinkage of a thermoplastic resin molded product, the optical distances from a read line to a photoelectric conversion element in the center and the two end portions in the longitudinal direction of the photoelectric conversion element are different. A thermally caulked combined structure is obtained by fixing an object to be fixed by thermal caulking by thermally deforming a plurality of caulking projections formed in the longitudinal direction of a molded product made of a thermoplastic resin and having a rectangular parallelepiped outer shape. Antiwarping grooves (15) are formed apart from the proximal portion of each caulking projection (12) of the molded product (4) before thermal caulking so as to sandwich the projection.
Abstract:
An image sensor unit includes: multiple first light guides that shape light emitted by light sources into a line and emit linear light elongated in longitudinal direction to an object to be read (P); multiple holding members that hold each of the first light guides on a frame; and an image sensor that detects light from the object to be read (P). The multiple first light guides are parallel, and in a range in which the image sensor detects the light from the object to be read (P) in the longitudinal direction of the first light guides, center positions in the main-scan direction of the multiple holding members that hold one first light guide of the multiple light guides and center positions in the main-scan direction of the multiple holding members that hold another light guide different from the one first light guide deviate from each other.
