Electrophotographic copying machine

Abstract

Abstract PURPOSE:To make the set number of copies withot blurring, by setting an orginal on receiving a signal sent in response to the end of a copying action, installing a timer for producing a signal after a prescribed time, and repeating the copying actions at intervals of given suspension times. CONSTITUTION:Setting of time length of a timer 39 is adjusted to about 4.0sec within 2.0 and 8.0sec by changing a variable resistor for fixing a time constant with a suspension time adjusting knob 38 to fix the suspension time. When the copying action of the last copy of a set number is finished, the action is paused, and an original on an original placing glass 1 is exchanged during this suspension time. When the time is up and the timer 39 produces an output, this output enters a copying action controlling circuit 43, and an addition counter 41 is cleared to start the copying action again, thus permitting the copying actions of a set number to be repeated at intervals of the fixed suspension time automatically, operation to be made easy, pressing the original to be copied by both hands to be made unnecessary, and blurring of an image to be prevented.
