Abstract
PURPOSE: To increase the controllability of the copying machine, by displaying the original replaceable period with action signal of a switch which opens and closes in cooperation with the original holding member, and timing signal at the end of exposure.
CONSTITUTION: When the original is placed on the platen and the original holding member is closed, the output Sg of a microswitch which cooperates therewith becomes low level, so that FF Q5 is not reset. In this state, when copying of specified number of sheets is over, and a count-up signal CUT and a reverse signal when the original platen moves backward at the end of exposure are inverted to high level, the FF Q5 is set through AND gates Q2, Q3, and an AND gate Q6 is opened by the set output of FF Q5, so that a transistor Q7 is made to conduct depending on the oscillation output of an oscillating circuit 4, thereby lighting up the lamp 24 only when the original is to be replaced. Therefore, negligence of replacement of the original may be prevented, and the timing for replacement of the original may be confirmed, thus contributing to the controllability of the copying machine.
