Abstract

PURPOSE:To display the number of copies adequately, by subtracting the count of image forming according to the size of recording body and jam occurring timing. CONSTITUTION:A sequence control computer produces jam signals 4-1 when paper feed port, transfer part, or paper discharge part detects jam. A copy count display device 102 adds up +1 to the number of copies made every time the optical system for original exposure is inverted. Signals 4-1 outputted from computer Q2, etc., are added to a control computer Q1, and the occurring timing of singals 4-1 and the +1 adding timing of display device 102 are compared with each other, so that jam is accurately judged according to the jamming location by the signals 4-1 even when the recording member is long. Then, a subtracting command of required number is applied from the computer Q1 to a decoder 103 depending on the sieze of the recording member and occurring timing of signals 1-4, so that the number of copies may be accurately displayed in the display device 102.
