Abstract
PURPOSE:To make it possible to provide a variable multiplication copying without complication its device by changing the transport speed of an original document only, but not changing the shifting speed of a photoreceptor and the transport speed of a copy material together with the variable multiplication copying. CONSTITUTION:In case sheet document is subjected to variavle multi-plication copying by means of the second exposure unit, if the multiplication rate of copying is 1: 1/n, and transport speed Vo of document at the equal size copying, the transport speed of document at the variable multiplication copying has the relation Vo:Vn=1:n. Next, let the central position of projection on the photosensitive drum 4 be B point, the tip position of copy material 39 be D point, and in case LBC=LDC, as soon as the document image starts to be project- on the B point, the copy material 39 starts to be transported; in case LBC<LDC, the copy material 39 is previously transported to a predetermined position E on standby before the document image starts to be projected at the position B. Accordingly, the variable multiplication copying can be assuredly done in a simple constitution.
