LIGHT EMITTING HEAD AND METHOD FOR PROVIDING LIGHT EMITTING HEAD

摘要

PROBLEM TO BE SOLVED: To provide a light emitting head used in a copier or a printer.

SOLUTION: The light emitting head has a certain irradiation length, such as a printing width or a copying width, and are made of bulk material. The light emitting head includes: a hard conveyance structure reaching at least the irradiation length of the light emitting head; and a plurality of blocks of optical elements arranged in array in a longitudinal direction. Blocks have a certain coefficient of head conduction. Each of blocks of optical elements has a first plane and a second plane, and contains a plurality of light emitting elements exposed to the first plane of the block.
