Abstract
PURPOSE:To perform image formation always in the specified position of transfer material by beforehand setting the timings for operating feed means according to plural copying magnifications and storing the timings having been thus set for the specified time thereby controlling the feed means. CONSTITUTION:The electrostatic latent images of the original placed on an original platen 12 are formed on the conductive member on a screen 13 and further the secondary electrostatic latent images are formed on the recording medium having been fed onto an insulation drum 24. Clutches CL3A-CL4 are so controlled that the leading end on this recording medium assumes the specified position relation. The timings at which the clutches CL3A-CL4 operate the positions of the lens systems 17-1-17-3 of this copying apparatus and the initial position of a mirror 16 are beforehand set in the Hall IC44 which outputs optical system home position signal OHP, the Hall IC45 which outputs optical system resist position signal ORGP and the Hall IC47 which outputs the home position signal DHP of the drum 24 and the timings having been thus set are held stored in RAM, etc. for the specified time, whereby the images are formed in the specified position on the recording medium.
