Abstract
A total contact type photoelectric conversion device comprises a substrate having an optically transparent portion, a plurality of photoelectric conversion elements formed in a line on the substrate, and a cover layer covering the plurality of the photoelectric conversion elements and having a roller load region within which the cover layer is to make contact with a sheet partially wrapped around a peripheral surface of a roller for feeding the sheet in a sub-scanning direction. The plurality of photoelectric conversion elements are aligned in a main scanning direction perpendicular to the sub-scanning direction and are located outside the roller load region. Therefore, incident light passing through the device is reflected on a position on the sheet outside the roller load region.
