Abstract: An image sensor module includes a light source unit that emits a linear light beam elongate in a primary scanning direction to an object to be read, and a lens unit including an incidence surface and an output surface oriented opposite to each other. The lens unit is configured to receive light from the object through the incidence surface and output the light through the output surface. The module also includes a sensor IC that receives the light outputted from the output surface, a housing that holds the light source unit and the lens unit, and a support member that supports the lens unit such that the incidence surface is located more distant from the sensor IC than the output surface in a secondary scanning direction. The support member includes a reflection surface that reflects the light from the object toward the incidence surface.

Abstract: A light source unit emits light for irradiating a document. A light guide in which light emitted from the light source unit propagates has a first exit part for emitting light to the document and a second exit part, which is a different part from the first light part, for emitting light to the outside. A corrective light receiver is disposed in an area receiving direct light of the light emitted from the second exit part, and outputs reference data corresponding to the direct light. A controller compares predetermined criterion data with the reference data output from the corrective light receiver, and performs processing for correcting a bright output based on a result of the comparison.

Abstract: Since a light emitting surface in a cross section perpendicular to the longitudinal direction of a light guide is formed to have a smaller width than a reflecting surface, light of an LED, which is incident from an end surface of the light guide and is scattered throughout the entirety of the longitudinal direction in the reflecting surface, is condensed toward the light emitting surface, and is then emitted in the form of a band toward a document from the light emitting surface. Therefore, it is possible to provide a CIS module including an illumination unit having a new configuration capable of illuminating a portion where the document and an optical axis of the lens array included in the lens unit intersect, in the form of a band with high efficiency using the illumination unit.

Abstract: A light guide inserted into an inclined groove is disposed so as to partially overlap with a lens unit that is fitted into a concave groove disposed parallel to the inclined groove when seen in a plan view, to regulate the separation of the lens unit from the concave groove and hold the lens unit in an insertion state by the light guide. Therefore, a fixing unit such as an adhesive agent is not required in fixedly disposing the light guide and the lens unit at a predetermined position of a frame, and a CIS module is assembled without using an adhesive agent, thereby allowing the CIS module that is easily disassembled when being discarded and that improves recycling efficiency to be provided.
