A copying machine of the Electrofax type having a stationary horizontal transparent support for receiving manuscript to be copied and a carriage mounted for horizontal movement beneath the transparency to effect optical scanning of the manuscript. The carriage supports means for feeding copy paper vertically past an image-receiving zone, a mirror which projects an image from the manuscript horizontally toward the image-receiving zone, lens means between the mirror and the image-receiving zone for focusing the image on the surface of the copy paper, a toner receptacle and means for feeding the copy paper therethrough after exposure thereof. Means are provided for moving the carriage horizontally in exact synchronism with vertical movements of the copy paper whereby a panoramic image from the manuscript is applied to the copy paper. The carriage-moving means includes a pulley mounted upon and rotated jointly with a paper feed roll and a traction cable wrapped about the pulley and adapted to be connected to opposite ends of the machine. Means are provided for tightening the cable whereby rotation of the pulley causes the pulley to rotate along the cable and thus move the carriage in synchronism with the paper feed roller. |
