Stencil printer having printing paper feed control structure

摘要

A stencil printer includes a rotary printing drum around which the stencil master is wrapped, a main motor which rotates the printing drum, a press roller which is rotatable in parallel to the printing drum in contact with the printing drum, and a pair of opposed conveyor rollers which feed a printing paper between the printing drum and the press roller so that the leading end of the printing paper meets the printing drum in a predetermined position of the printing drum. A conveyor roller motor is provided separately from the main motor and drives the conveyor rollers. A reference position sensor detects a reference position on the printing drum, a printing drum rotation detector detects rotation of the printing drum on the basis of the reference position, and a conveyor roller rotation detector detects rotation of at least one of the conveyor rollers. A conveyor roller controller controls the conveyor roller motor on the basis of the rotation of the printing drum and the rotation of the conveyor roller so that the leading end of the printing paper meets the printing drum in the predetermined position of the printing drum.
