Abstract

An optical reading head is an optical reader for photoelectric reading of images on a medium, comprising a plural light-emitting optical fibers for transmitting beams of light from light emitting elements to the surface of the medium, and plural light-receiving optical fibers for transmitting beams of reflected light from the medium surface to light-sensitive elements. The ends of the light-emitting and light-receiving optical fibers opposite to the medium surface are positioned in first and second rows, respectively, at a predetermined pitch. The ends of the light-receiving optical fibers are displaced relative to the ends of the light-emitting optical fibers along the first and second rows by a distance equal to a half of the predetermined pitch. Also disclosed is an optical reader comprising the above-described optical reading head, and a control device for controlling the operations of the light emitting elements, so that the resolution of the reading head is variable in two steps.
