ABSTRACT:
In an LED head, a photosensitive drum is positioned with reference to an upper surface of a circuit board on which surface at least one light-emitting element is supported in order to accurately set the distance between the light-emitting element and a photosensitive drum. Further, clips and a spring are used to accurately set the distance between the light-emitting element and a lens and to simplify the process of production.
