Description

Technical field

[0001] The present invention relates to an LED print head suitable for an electrophotographic copier or printer, a method for manufacturing the same, a method for manufacturing an LED substrate, and a method for adhering an LED substrate. Background technique

[0002] The first LED writing head in the past (Japanese Patent: JP 7-108709), such as Picture 12 As shown, the two protruding parts P at the center of the upper surface of the box H having a U-shaped cross section are used to fix the two side surfaces of the rod lens L, thereby arranging the rod lens, so the field of view of the photoreceptor is The angle α is large, and it is difficult to reduce the thickness. Therefore, there is a problem that it is not suitable for tandem colorization. The tandem type is a method in which cyan, magenta, yellow, and black photosensitive drums are arranged in a row using a plurality of imaging drums to form a color image.

[0003] In addition, the conventional second LED ...
