<p>PURPOSE:To increase the output light of an optical recording head by using a reflecting mirror which makes output light from a light emission part incident on a lens array and forms the image of the output light of the lens array on a photosensitive body. CONSTITUTION:The output light of an LED array 2 is incident directly on the rod lens array 3 and also reflected by the reflecting mirror 5 to enter the rod lens array 3. The incident light after being reflected forms an image at the position 6 of a virtual image, but can form an image at a regular position because of a reflecting mirror provided on the image formation side of the rod lens array 3. Consequently, the rod lens array is arranged almost in parallel to an LED base substrate and light is outputted from the head-side end surface. For the purpose, the output light of the LED array 2 is changed in optical axis by using a reflecting mirror 7 and outputted from the head-side end surface to narrow down the width of the head in the circumferential direction of a photosensitive drum 4, thereby reducing the size of a recording device.</p> |
