Abstract

1,261,860. Electro-photographic copper. DEVELOP G.m.b.H. APPARATEBAU. May 5, 1970 [Jan. 8, 1970], No. 21567/70. Headings G2A and G2H. The image of an original 27 is projected on to a charged copy sheet 8 by an optical system comprising a silvered lens 15 and mirrors 16, 17. In use, sheet 8 is fed by endless belts 2 until the sheet actuates a micro-switch (not shown) to stop the belts. A motor then rotates a pinion 26 joined to a housing 18. Pinion 26 engages a rack 24, thus driving housing 18 so that the optical system therein line-by-line scars the original 27. A diaphragm 21 is adjustable via a rack 23 by means of a manually rotatable pinion 22. For Figure see next page
