ABSTRACT:
An optical printer head with a light emitting diode array comprises means for setting a distance between a light emitting surface of a light emitting diode array chip and a rod lens array. The means is provided with two reference position levels at which the light emitting diode array chip and the rod lens array are held. Therefore, there is no necessity for adjusting the distance between the light emitting diode array chip and the rod lens array so that a productivity thereof is much improved.
