Paper aligner mechanism for copier

Abstract

Abstract PURPOSE:To reduce screw in paper feed in a paper aligner mechanism for copier, by providing the shaft of an aligner roll rotatably around a fulcrum and varying the roll angle with correspondence to the reaction force functioning onto the roller. CONSTITUTION:When travelling (aligning) a paper 7, the aligner 1 is positioned as shown by solid line to feed the paper 7 along a guide 8. When the end section of paper 7 will travel along the guide 8, and load against the paper carrying force to be produced through lateral component P1 of the paper carrying force P will increase and function as the reaction force to bring the roll 1 between the solid line and the dashed line. Consequently, the force for pushing the paper 7 obliquely against the guide 8 will decrease. Upon contact of the paper 7 against the tip of a transport roll 9, the roll 1 will start slipping against the roll 1 and come to the dash line position as the reaction force increases. Since the direction of the carrying force P will be same with the advancing direction of paper, the next paper can be fed without screw.
