<p>PURPOSE:To shorten the width of a head in the peripheral direction of a photosensitive drum, and to miniaturize an LED printer by outputting the output light of an LED recording head from a head side end face by a mirror. CONSTITUTION:As for a microlens array 3 and a mirror 5, its positions are set so that a light beam emitted from an LED array 2 is reflected in the direction of a head side end part by the mirror 5, passes through the microlens array 3, and an image is formed on a photosensitive drum 4. In this regard, the adjustment of an image forming position of an emitted light is executed by the microlens array 3 or the mirror 5. Also, by an integrating jig 6 for integrating the mirror 5 and the microlens array 3, the number of parts is decreased, and its position can be easily adjusted. In this way, the width of a head in the peripheral direction of the photosensitive drum can be shortened, and an LED printer can be made small in size.</p> |
