<p>PURPOSE:To correct irregularity in the quantity of light without lowering the level of the quantity of light while reducing the size of a device and eliminating the need for adjustments by providing a vibration generating means to a light emitting source array or reflecting means. CONSTITUTION:A photosensitive drum 1 rotates as shown by an arrow and a liquid crystal shutter array 2 and an LED array light source 3 are arranged opposite each other in its generating-line direction. The array 2 is controlled by a display driving circuit 4 to pass or cut off light from the light source 3, forming a latent image of a display image on the drum 1. A vibrating 5 is a vibrating body fitted to the light source 3 in one body and a couple of piezoelectric vibrators 6 and 7 are fitted on both surfaces of part of its lengthwise one-side end part in one body. An oscillation part 8 drives the vibrators 6 and 7 to vibrate the light source 3 in its array direction through the vibrating body 5.</p> |
