Abstract
A drum rotating about its longitudinal axis is also moved so that this axis describes a closed path. A given portion of the drum locates positions about this path at which an image is applied to and removed from the portion the speed of the portion falling at these positions and rising between them. As shown in Fig. 1, a photoconductive drum 10 is carried by an arm 16 about an axis 18 and is rotated by frictional contact with constraining means 20. A particular point on the drum's surface follows a path 40 to locate the usual electrophotographic working stations at 42, 44, 46, 48, 50. In a modification, Fig. 8 (not shown), the drum traverses an elliptical path. A printing device, Fig. 6 (and Fig. 7, not shown), comprises a number of such drums 110 spaced by gears 130 and located in a constraining means 132 with stations for charging 134, developing 136 and cleaning 138. Three such assemblies are mounted on a head 108. Images are reflected via a mirror 126 on to the drums. Each time a drum prints a character on a web 133 the head 108 rotates by one character space. As one assembly finishes a line, the next assembly on the head 108 is ready to start the next one. This may be done by continuously moving the web 133 to obtain slanted lines.
