<p>PURPOSE:To form an image with high image quality at a sensitizing element by bringing a substrate into contact so that a lens array and an image element array may face a substrate contact datum surface formed in a housing at regular intervals. CONSTITUTION:A light emitting diode element array 2 placed on a substrate 1 consists of light emitting diodes 2a, and the light emitting diodes 2a emit light selectively individually according to an external electric signal to form a latent image for forming an image by irradiating the emitted light to the surface of a sensitizing element 5. For fixing the substrate 1 where the light emitting diode element array 2 is mounted on the housing 4, a substrate contact datum surface 4a is formed below the housing 4, the top surface of the substrate 1 where the light emitting diode element array 2 is mounted is brought into contact with the datum surface 4a, and the bottom surface of the substrate 1 is pressed to the housing 4 side by a metallic substrate 8 which is locked at the housing 4 and where micro plastic-deformed parts are dispersed.</p> |
