Abstract
An image sensing head of an image reading device and a method of producing same are disclosed. The image sensing head includes a plurality of optical fibers and light emitting and light receiving elements supported in a manner to provide a unitary structure. The optical fibers of the light emitting side and the optical fibers of the light receiving side are each formed as a sheet and arranged such that the read-out ends of the optical fibers of the light emitting side are located in positions in which they supply read-out light beams to an image surface of a document and the light emitting ends thereof are located in positions corresponding to those of the light emitting elements while the read-out ends of the optical fibers of the light receiving side are located in positions in which they receive light beams reflected by the image surface of the document and the light receiving ends thereof are located in positions corresponding to those of the light receiving elements.
