Definitions

  • the linear light emitting head 46 is formed by linearly arranging a plurality of end emission electroluminescent elements.
  • Each end emission electroluminescent element is formed by sandwiching an active thin film, such as a thin film of zinc sulfide containing an active element, between dielectric thin films and attaching electrodes respectively to the dielectric thin films. Voltage is applied individually across the pairs of electrodes to make the end emission electroluminescent elements emit light indi­vidually.
  • Slots 55 for receiving the screws 45 therethrough are formed in the inclined wall 43 of the frame 42 so that the plate 44 can be moved along the inclined wall 44 and fastened to the same at an optional position in adjusting the gap between the linear light emitting head 46 and the circumference of the photoconductive drum 24.
  • the respective image forming points of the exposure units 31 and 32 as disposed in the housing chamber 33 on the circumference of the photoconductive drum 24 coincide with each other.
  • the optical path is fixed with respect to the photoconductive drum 24 when the electrophotographic copying machine is equipped with either the exposure unit 31 or the exposure unit 32, the parts of the units other than those of the exposure unit 31 or 32 can he arranged closely, so that the electrophotographic copying machine can be formed in a compact construction.
  • the edge of the rear wall 147a of the light emitting section with respect to the rotating direction of the photoconductive drum 121 is closer to the circumference of the photoconductive drum 121 than the edge of the front wall of the light emitting section.
  • reference faces 148 are formed opposite to the circumference of the photoconductive drum 121 respectively in the opposite ends of the light emitting section of the case 136.
  • lugs each provided with a vertical slot 150 project respectively from the upper opposite ends of the light emitting section of the case 136.
  • Screws 134 are screwed through the slots 150 in the holding plate 130 to fasten the case 136 to the holding plate 130.
  • Eccentric cams 152 are fixed to the opposite sides of the case 136 with screws 151, respectively.
  • the holding plate 130 is fixed to the holding frame 118 with screws 153.
