Abstract

PURPOSE: To correct skew that occurs in paper by weakening the pressing force of a feed roller upon platen by a pressing force variable mechanism to let a resist claw contact the peripheral surface of the platen thereby feeding the paper at the feeding of the paper.
CONSTITUTION: When paper 3 comes to near a rear feed roller 4 along a paper guide 2, the entry of the paper is detected by a photosensor 19 which in turn causes a motor 31 to run to rotate a cam shaft 35 by way of gears 32, 33, 34, causing a pressing force variable cam 36 to rotate in the arrow B direction. A lever 39 engaging with this then rotates in the arrow A direction to rotate a shaft 9 clockwise. Since this causes the direction of the mounting portion of a leaf spring 8 to change, the force of the spring 8 becomes weak to lower the pressing force of the feed roller 4 which is pressed by a platen 1. In addition, a resist-releasing cam 35 and a lever 16 actuate to let the shaft 14 rotate counterclockwise, causing the end of a resist claw 13 to contact the peripheral surface of the platen 1. As a result, the paper 3 is fed forward and its leading end contacts the contact surface of the resist claw 13.
