Abstract

PURPOSE: To prevent misoperation of the original automatic feeding device, by canceling the usable state of the setting means to set the original automatic feeding means in the usable state unless the original is set within the specified time.
CONSTITUTION: While the copying machine main body is free from jamming and other abnormality, and a lamp 610 is lighting, and the original is not placed in the exposure position or the feeder, the signal POS becomes low level, and the output of AND gate 623 becomes high level, and an FF 617 is set, so that a timer 618 starts to count the time. When the original is set in place while counting the time, the timer 618 is reset, and a timer 619 is set, then the output of NOR gate 622 is inverted to high level after lapse of specified time, so that AF usuable signal A is produced by AND gate 626. Thus, copying with AF is started. Therefore, even when the original is set in the feeder after lapse of time counting by the timer 618, the AF usable state is not established, so that the original may not be fed automatically at the time of misoperation when, for instance, a next user puts the original in the feeder by mistake after end of copying.
