Abstract

PURPOSE:To eliminate the inconveniences accompanied with idle feeding of originals by providing a means of storing the number of sheets of the originals before feeding, a means of counting the number of sheets of the originals after exposure and a means of emitting a warning signal when the numbers of sheets of both do not coincide. CONSTITUTION:Both number-of-sheets-signals from an original number-of-sheets- memory means 22 inputted from ten keys and an original number-of-sheets counting means 23 inputted from a detecting member 9 are compared by an arithmetic part 24. When both signals do not coincide as a result of, for example, subtraction, a warning signal is emitted to an overlap feed display part 19.
