Abstract: A print medium feed device and a stencil printing machine employing the same are disclosed wherein a print medium as a print sheet, transferred with a pair of secondary paper feed rollers, is transferred through a pair of transfer guide members to a press drum by which transfer of the print medium is succeeded. An upper transfer guide member, with which the print medium is brought into sliding contact, is periodically shifted between a guide position to allow the print medium to be guided to the press drum, and an inoperative non-guide position in which the upper transfer guide member is separated from the other transfer guide member. A shaft of one secondary paper feed roller is exerted with a rotational braking effect by a torque limiter, whose rotational braking effect is periodically released by a clutch unit.

Abstract: 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.
