Abstract
PURPOSE:To enable size reduction by simple structure and easy confirmation of blank exposure condition, by using one lamp both for illumination of the original to be copied and for illumination of blank exposure. CONSTITUTION:In exposing original O with short-focus small imaging element array 4, plate 16 is restored to the full line position with rotary solenoid 17, the light path between array 4 and original O is opened, and the static latent image of original O is formed on photoreceptor 1'. When plate 16 is inclined to the broken line position, the light path between them is interrupted, the light emitted from lamp 6 is reflected and falls on array 4, and this uniform illumination light is used for blank exposure. The light emission amount of lamp 6 during blank exposure is set to a lower level than that during illumination of original O for forming a latent image, permitting power consumption to be cut down and temperature rise of the inside of copier to be prevented.
