Abstract

1,064,852. Photo-copying apparatus; electrophotography. DENNISON MANUFACTURING CO. Ltd. March 2, 1964 [March 8, 1963], No. 8757/64. Headings G2A and G2H. In a photographic or electrophotographic projection copying apparatus, the original is placed on transparent plate 5 beneath cover 6 and illumined indirectly by four lamps such as 15, 16 which have pivotally adjustable baffles 22 and direct light to the diagonally opposite corners of chamber 1. Lens 12 projects an image on to the photo-sensitive web 8, fed by rollers 9, 11, after reflection at mirror 13. The walls of chamber 1 are specularly reflecting. The apparatus forms part of the disclosure of Specification 1, 064, 851.
