Controlling apparatus for paper-feeding drive operated by driving system of optics unit for exposure

摘要

A photocopying machine having an optical system for scanning a document to be copied, including a reciprocating portion capable of forward movement for scanning and reverse movement for recovery, which movements are produced by corresponding forward and reverse rotation of a drum. The device also contains a paper feeding drive comprising a controlling cam adapted to rotate with the drum and control the driving of a paper feeding roller to feed the recording paper. The improvement is a controlling apparatus for the paper feeding drive wherein rotation of the paper feeding roller is suspended during at least a part of the reverse movement of the reciprocating portion while a sheet of paper is being fed from the paper supply to the paper feeding drive.
