ヘツドの防塵装置。 The focusing rod is attached to an optical printer head consisting of a light emitting diode array fixed to a substrate and a focusing rod lens array that projects light emitted from the array toward a photoreceptor on which an electrostatic latent image is to be formed. A translucent dustproof cover covering the light emitting end face of the rod lens array is provided so that it can be inserted and removed by parallel movement along the longitudinal direction of the rod lens array, and the peripheral edge of the dustproof cover is extended to approach the surface of the photoreceptor. A dustproof device for an optical printer head, characterized in that a dustproof wall is formed.
