<p>PURPOSE:To take a copy with high resolution at a high speed by averaging light from a spot light source through an integration cylinder and making it incident to the circular part of an optical fiber bundle, arraying optical fibers in a plane and emitting the light as linear light, and opening and closing microshutters. CONSTITUTION:Luminous flux from the spot light source 1 which is turned on by a power source 6 is changed in direction by a mirror 24 directly or after reflected 21, heat rays are cut 22, and the light is passed through a band-pass filter 23. Then, the luminous flux is averaged through a plano-concave lens 34 and the integration cylinder 35 and allowed to made incident on the circular end part 3' consisting of numbers of optical fibers 3. Light outputted from the optical fibers 3 is reflected by an elliptic mirror 37 of acryl after a total reflection treatment to irradiate a liquid-crystal panel 4. A control circuit which is not shown in a figure opens and closes respective liquid crystals of the liquid-crystal panel 4 to form an image on a photosensitive body B which rotates as shown in a figure through a lens array 5. Thus, a copy with high resolution is taken at a high speed.</p> |
