A residual amount in the discharged stencil sheet box is displayed, a superior compression is performed against the discharged stencil sheet and many stencil sheets can be stored in the box. When the perforated stencil sheet 22 transferred by the feeding means 41 into the discharged stencil sheet box 42 is compressed by the discharged stencil sheet compression plate 43, the encoder 50 is utilized for detecting moving amount and compression force of the plate 43. When the pulse width of the pulse generated from the encoder 50 becomes a predetermined value, it is discriminated that the compression force with the plate 43 reaches a desired value, and the compression motor 44 is stopped. The number of pulses generated by the encoder 50 is counted to detect the moving position of the plate 43 and the residual amount in the box 42 is displayed in response to the moving position.
