In the print head in which the array 3 is arranged, both ends of the self-occurring lens array 3 are closed by a pair of opposing elastic members 15 having equal elastic forces from the light emitting surface 2a of the light emitting diode array 2 and the photosensitive surface 1a of the photoreceptor 1. The center line of the gap equal to the focal length of the self-occurring lens array 3 formed by the light-emitting surface 2a and the photosensitive surface 1a and the center line of the self-occurring lens array 3 are held so as to press the edges. A self-occurring lens holding structure for an optical printer head, characterized in that C is held in alignment. (2) The self-occurring lens holding structure for an optical printer head according to claim 1, wherein a coil spring is used for the elastic member 15.
