Zusammenfassung:PURPOSE:To automatically confirm the remainder of plural cut papers by providing a switch to turn ON and OFF by the moving action of a moving piece having a mutually different contacting position and detecting with the combination. CONSTITUTION:Moving pieces 14 and 15 which are formed to mutually different approximately chevron shapes and in which respective contact positions for a cut paper 13 are mutually different, and switches 11 and 12 having photo- interrupter type optical sensor 16 and 17 to turn ON and OFF by these respective moving pieces are provided in parallel in the upper direction of the cassette for housing the cut paper. A detecting mechanism 18 is connected to the switches 11 and 12, a signal is received from the optical sensors 16 and 17 and by the combination of the ON and OFF of the switches 11 and 12 due to the moving action of the moving pieces 14 and 15, the cut paper housing condition is detected. The remainder of the detected cut paper 1 is displayed in a display mechanism 19.
