Abstract
PURPOSE:To make it possible to detect an abnormality even before the copying paper reaches the detection means by providing the detection means and a timer on a conveyance passage of the copying paper. CONSTITUTION:A detection switch 3 is arranged on a conveyance passage 2, and is set so as to be turned on when the leading edge of the copying paper 1 reaches the switch 3 and to be turned off when the copying paper 1 has passed past the switch 3. A timer 7 is set at a time T0 somewhat longer than a normal elapsed time required for the swtich 3 from the detection of the rear edge of the copying paper 1 to the detection of the leading edge of the succeeding copying paper 8, and genrates a signal to indicate an abnormality when an arrival at the switch 3 of the succeeding copying paper 8 is delayed. Accordingly, an abnormality occurred before the leading edge of the copying paper 1 reaches the detection means can be detected.
