<p><P>PROBLEM TO BE SOLVED: To provide an optical print head capable of performing light exposure by each light emitting element with a required amount of light exposure. <P>SOLUTION: The optical print head includes: a substrate; a light emitting element array consisting of a plurality of light emitting elements arranged in a row on the substrate; and a driving circuit part for driving the light emitting element array provided on the substrate. The driving circuit part has a plurality of driving elements arranged in a row corresponding to a plurality of the light emitting elements, an electric potential supplying circuit for supplying an electric potential to one terminal of a plurality of the driving elements, and a signal wiring for connecting a plurality of one terminals and an output terminal of the electric potential supplying circuit. The signal wiring has a common signal wiring connected with the output terminal of the electric potential supplying circuit, and a plurality of individual signal wirings extending toward respective driving elements so as to be divided from the common signal wiring. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
