Abstract

1,017,396. Electrophotographic apparatus. W. ZINDLER, [trading as LUMOPRINT ZINDLER KOMM-GES]. July 12,1962 [July 25, 1961], No. 26903/62. Heading G2H. An electrophotographic copying apparatus comprising a charging, exposing, developing and fixing devices, the developing and fixing devices being disposed in the upper part of the apparatus and beneath a substantially horizontal guide path for electrophotographic material and including a roller for applying developer, and in which a plurality of mutually spaced and parallel bladeshaped guide members which extend above the guide path from the vicinity of the roller in the direction of advance of the material, are provided, the guide members being shaped adjacent to the roller so that the lower edges of the guide members extend towards but are spaced from the roller so that the leading edge of the material is pressed down towards the roller and the developer, and in which a curved supply path is provided for deflecting the material into the guide path so that the leading edge of the material is directed towards the shaped edges of the guide members. As shown, the apparatus comprises two inlet slots 7 and 8 separated by a V-shaped guide ink which the copy material and the original are respectively fed and guided to stations 12 and 13 by rollers 14 and 15; the copy sheet being charged by electrodes 19 and 20 beneath grid 16. The original is reflex exposed at 13, the image rays passing through objective 30 and reflected by a mirror along path 32 on to the copy sheet at 12. The copy sheet is then guided through rollers 26 and curved guide plates 24 and 25 on to the longitudinal strips 51 which have curved edges 60 to press the sheet into contact with but not to cut the magnetic brush 57 on the roller 36 or with a liquid developer if this is used in which case a drying station 39 is employed which is placed below vests 53. After passing the developer, the copy sheet is fixed by infra-red radiators 39 in shield 40 before passing through rollers 42 and 43 and out through slot 45. All the rollers are driven by a common transmission and there are separate circuits for the light sources 29 and the heat sources 39 and for the electrodes 20; the transmission and the power sources being controlled by two master switches.
