IMAGE SENSOR UNIT AND IMAGE READING APPARATUS

摘要

An image sensor unit includes a sensor substrate on which a plurality of photoelectric conversion elements are mounted, a light source that includes light-emitting elements, for illuminating a document, a light guide that guides light from the light source from one end face and linearly illuminates the document, a rod lens array imaging reflected light from the document on the sensor substrate, and a frame holding each of these elements. The frame includes a spacer provided in proximity to the light source. The spacer includes a light shielding that covers the light source and a portion of the light guide.
