Zusammenfassung:	1,079,890. Photographic copying apparatus. AGFA A. G. AND GESELLSCHAFT FUR MULTIBLITZGERATE DR. ING. D.A. MANNESMANN m.b.H. June 2, 1965 [June 4, 1964], No.23549/65. Heading G2A. A photographic element which is sensitive to flash exposure is placed in contact with an original to be reproduced and guided around a glass cylinder 2 by an endless conveyer belt 7 and is exposed by ignition of a flash tube 1 inside the cylinder. Insertion of the element into guide 8 operates contact 161 to start a driving motor for the conveyer belt 7 and for rotation of cam 12. Projection 121 on the cam operates switch 13 to ignite the tube 1 when the element has been fed into position around the cylinder and recess 1211 allows switch 14 to open and stop the motor upon delivery of the element. The voltage applied to the flash tube is controlled by a stabilizer circuit and is adjustable, the flash time of the tube is 1 x 10-3 to 1 x 10-4 seconds, and the power input is 600 to 1000 watt-seconds.
