ABSTRACT:
A counter control device for an electrophotographic copying machine of a type having a preset counter device is selectively operable in one of a multi-copy mode wherein a copying operation is repeated to produce a plurality of copies while copying papers which are to have an image affixed thereto are automatically fed one at a time and a manual feed mode wherein the copying operation is carried out by the use of copying papers which are to have an image affixed thereto and which are fed manually one at a time. The counter control device includes a counter for counting the number of copies being made or left unfinished each time one cycle of the copying operation is completed. The counted value is displayed by a display unit which is also operable even when the machine is set to operate in the multi-copy mode.
