<p><P>PROBLEM TO BE SOLVED: To suppress printing unevenness when printing using an optical printer head. <P>SOLUTION: This optical printer head includes a plurality of light emitting parts arranged along a main scanning direction on the surface of a substrate, and an imaging optical system for imaging light emitted from the plurality of light emitting parts, in imaging positions separated for every light emitting part. In the imaging optical system, a plurality of rod lenses with one end faces facing the substrate surface are arranged in a line in the main scanning direction. A plurality of light emitting parts are arranged in each region, facing the end face of the rod lens, of the substrate surface, and a plurality of light emitting elements formed on the substrate surface are arranged at each light emitting part. The spacing along the main scanning direction of the adjacent light emitting elements is narrower than the spacing along the main scanning direction of the adjacent light emitting parts. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
