Stencil printing machine, stencil discharge apparatus and stencil printing system

A stencil discharge apparatus for a stencil printing machine with a printing drum, comprising:

• a discharge box for storing a predetermined amount of stencil sheets after being peeled off from the printing drum;
• stencil sheet residual amount calculating means for calculating a residual amount of sheets which can be stored in said discharge box in reference to a storing limit amount of said discharge box and a storing amount of the stencil sheets already discharged into said discharge box;
• means for inputting a number of originals to be printed, said number of originals being inputted prior to a situation where processing accompanied by discharging a plurality of the sheets is performed in a continuous manner;
• and
• control means electrically connected to the calculating means and the inputting means for comparing said number of originals inputted at the inputting means with said residual amount calculated at said calculated means, said control means having an alarm operating when said number of originals is more than the residual amount.

A stencil discharge apparatus for a stencil printing machine having a discharge box for storing a predetermined amount of stencil sheets after being peeled off from a printing drum so as to discharge said stencil sheets, said stencil discharge apparatus comprising:

• compressing means having a compressing plate for compressing the stencil sheets discharged into said discharge box by a movement of the compressing plate;
• compressing pressure sensing means cooperating with the compressing means for sensing and outputting a compressing pressure of said compressing means;
• moving amount sensing means connected to the compressing means, said moving amount sensing means sensing as a continuous value an amount of the movement of said compressing plate as the compressing plate is moved and outputting the amount of the movement when said compressing pressure sensing means senses the predetermined pressure;
• and
• control means electrically connected to the compressing pressure sensing means and the moving amount sensing means for calculating a residual amount of stencil sheets capable of being stored in said discharge box on a basis of a storing limit amount of the discharge box and the amount of the movement sensed by said moving amount sensing means when said compressing pressure sensing means senses a predetermined pressure upon completion of compression of the stencil sheet with the compressing means.
