Abstract
Discharged stencils stored in a discharged stencil box of a stencil printer are compressed by a compression member driven by a DC compression motor. The cycle rate of pulses generated from a rotary encoder representing the speed of the compression motor is detected and the compression motor is stopped when the cycle rate of the pulses generated from the rotary encoder becomes equal to a value corresponding to a predetermined desired output torque of the compression motor.
Claims10
A method of compressing discharged stencils by a compression member driven by a DC compression motor to compress the discharged stencils, the method comprising the steps of detecting the cycle rate of pulses generated from a rotary encoder representing the speed of the compression motor and stopping the compression motor when the cycle rate of the pulses generated from the rotary encoder becomes equal to a value corresponding to a predetermined desired output torque of the compression motor.
A discharged stencil compressing apparatus for a stencil printer comprising a compression member driven by a DC compression motor to compress the discharged stencils, a rotary encoder which generates pulses representing the speed of the compression motor, a compression detecting means which detects the cycle rate of the pulses generated from the rotary encoder and generates a detecting signal when detecting that the cycle rate of the pulses generated from the rotary encoder becomes equal to a value corresponding to a predetermined desired output torque of the compression motor, and a control means which stops the compression motor upon receipt of the detecting signal from the compression detecting means.
