Abstract

PURPOSE: To raise the reliability of the clamp by a method wherein a sheet clamping pawl is energized in the direction of closing the tip of the sheet by the action of the centrifugal force caused by the high-speed rotation of a drum in the state that the tip of the sheet is absorbed and thus the slippage of the sheet is prevented.
CONSTITUTION: On feeding paper, the drum 20 is rotated at a low speed the sheet S is fed under the condition that the sheet clamping pawl 23 is opened by the action of a spring 31. Then the edge of the tip of the sheet strikes against the stopper 25 of the sheet clamping pawl 23, the tip of the sheet S is absorbed to a hole 36 by the air suction from a sucking port 36, while the drum 20 completing the sheet clamp rotates at a high speed, and thereby the centrifugal force acts on a weight 35 fixed to the free end of a lever 30 united with the sheet clamping pawl 23 through the intermediary of an axis 28. When the weight 35 is moved, by this constitution, the lever 30 is shaken, the sheet clamping pawl 23 moves in the direction of contacting with the surface of the drum and thereby presses the tip of the sheet S.
