Abstract

PURPOSE: To improve a feed paper separating function by a system wherein an arm comprising a friction element is supported at the width direction center of the friction element, keeping the friction element into contact with the paper feed roller with a spring.
CONSTITUTION: A separation friction element 210 is provided to the arm 200, a nip starting element 200a affixing the Teflon tape having a low friction factor. The arm 200 is supported by the trailing arm as a fulcrum which is fitted slightly on the axle 220 located on the bracket 260 secured with the main body, where the bearing width is narrow in locating at the center of the friction element 210 width and provided at the front side against the rotation direction of the roller 100. The friction element 210 presses the roller 100 with the spring 230. This enables the compression force applied to the paper feed roller of the friction element to become equal in the lateral direction for preventing the paper from skewing. Besides, this allows to widen the contact area between the friction element and the roller for preventing double feeding of the paper.
