<p><P>PROBLEM TO BE SOLVED: To provide an optical printer head which can be made compact by eliminating a microlens array and can increase the efficiency of light utilization. <P>SOLUTION: In the optical printer head which uses an inorganic EL element 20 as a light emitting element formed at one face 11 side of a glass substrate 10 as a light source 100, the other face 12 of the opposite side to the one face 11 of the glass substrate 10 is made a light extraction side face from a light emitting part 26 of the inorganic EL element 20. A lens part 30 with a lens action is set integrally with the glass substrate 10 at the other face 12 of the glass substrate 10. <P>COPYRIGHT: (C)2004,JPO</p> |
