Abstract

PURPOSE:To make it possible to operate the device synchronized with the next paper feed timing by stopping the action of the first carrying part when sheets of paper missed to be fed is detected after excessive paper sheet is fed to the second carrying part by means of a separating means when multi-feed is detected in a feed controlling device of a copying machine, etc. CONSTITUTION:A timer 2 starts to operate when paper feed is started, and when elapsed time until the rear end of the paper is detected by a sensor 50a is longer than the set time, presence of multi-feed is determined, causing a timer 3 to be turned on to allow a clutch OP for driving an optical system to be turned on via a driver DR3. Moreover, when a timer 4 having been set to the time ranging from the optical system-on to the next paper feed is set and turned off, a paper detecting sensor DS2 is turned on, and when the output is H, the first carrying part clutch FFC is turned off to be stopped, allowing the feed timing control of the remaining paper to be performed by means of an multi-feed separating roller. Then, when the first feed part is turned on, a clutch for driving a regist roller is turned on, permitting the optical system to return to the home position to cause the clutch PC for driving a paper feed roller to be turned on to perform paper feed.
