<p><P>PROBLEM TO BE SOLVED: To provide an optical writing head which can make it unnecessary to adjust an optical-axis direction to a rod lens array-a light emitting element array chip by enlarging a permissible range width of the optical adjustment. <P>SOLUTION: The optical writing head has the light emitting element array chip equipped with a spherical lens or composite lens on each light emitting point. A distance between a fixing surface of a first fixing part which fixes an erect equal-magnification lens array and a fixing surface of a second fixing part which fixes the light emitting element array chip is maintained by a predetermined distance. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
