Abstract
1289556 Electro-photographic apparatus ADDRESSOGRAPH-MULTIGRAPH CORP 30 Dec 1969 [21 Jan 1969] 63365/69 Heading G2H An electro-photographic apparatus has a photo-conductive member in the form of an endless belt 420 provided with marks 530, 539 which are sensed by means such as photo-cells 524B cooperating with a light source 524A to control the operation of the apparatus. A glass plate 404 receives an original to be copied for illumination by a flash source (not shown). An optical assembly for projecting an image of the original on to a planar position 424 of the belt 420 comprises mirrors 412, 414 and a lens 416 slidably mounted on rods 419 actuated by a linkage 421 for varying magnification. A corona discharge 432 charges the belt 420 uniformly, in advance of imagewise exposure. A paper feed assembly feeds copy sheets to a pressure transfer station 440 to receive a developed image from the belt 420. Copy sheets S are stacked on a vertically movable pile table 442 to bring the top sheet into contact with a feed wheel 446 controlled between a feeding and raised position by a solenoid 478 actuated for each sheet by a detector 588. Sensing devices 520B, 522B, 524B and 526B, such as photo-cells, sense the marks 538 and 539 to control the operation of the apparatus through a control circuit, Fig. 16 (not shown), which controls operation of corona discharge 432, feeding, the energization of the flash source, the drive to the developing apparatus and transfer of the developed image to a copy sheet. The control circuit includes a selector for the number of copies of each original required. In another embodiment, Figs. 2 and 11 (not shown), an assembly (58) carrying an endless photo-conductive belt is pivotally raised into an inoperative position. An exposure station (164) Fig.10 (not shown) includes a transparent cylinder (178) housing a tubular lamp (not shown) such that as an original passes between the photoconductive belt and the cylinder light is emitted through an elongated slot (188) to form a latent image on the belt. The sequence of operation is controlled by cam operated switches, Fig. 11 (not shown) in this embodiment. The photo-cells may be replaced magnetic detectors, or optical detectors sensitive to different types of radiation in conjunction with markers such as transparent materials or electromagnetic detectors sensitive to a charge carrying marker.
