Abstract

PURPOSE: To prolong the service life of the photosensitizer in a copier, input of copy size and timing signals are used for a copy start control signal output to indicate a possible time limit of copy starting according to the size of copy setting.
CONSTITUTION: A sheet type photosensitizer 1b is wound on the drum 1 and fixed by a solid bar 1c. The drum shaft 1d is attached with a disk 2a having four slits 31 to 34 which correspond to copy sizes and is angled with the solid bar 1c as reference. In order to detect each slit, phototransistors 61 to 64 are lined in straight in the radial direction of the slitted disk 2a. These transistors 61 to 64 and inverters 71 to 74 constitute a timing signal generator. At setting copy size, size signal and timing signal from the generator are put into the electric circuit 8 which determins copy start zone according to each copy size.
