Title: Automatic paper feeder for sheet member
Inventor: MATSUMOTO HIROAKI
IPC: B65H3/06
Filed: 1985-03-04
Abstract: PURPOSE:To prevent damage of the surface of a document and rising of a separating piece on the upstream side and to reliably feed a document by providing a friction member of the first separation and feed means, the downstream forward end portion of which is formed by material having a low coefficient of friction, and bringing the forward end portion into contact with the downstream document guide to slide. CONSTITUTION:When a upper unit is closed downward, the first separation piece 21 is operated to slide along the upper surface of a lower document guide 39 in direction of an arrow Q. The forward end of the first separation piece 21 shown at a portion M is formed by an aluminum die casting, so that the separation piece can smoothly slide in direction of the arrow Q. Accordingly, the upstream side of the first separation piece 21 rises to completely prevent a rubber portion and the top of a square roller 29 from being out of contact with each other. Thus, it is possible to thoroughly eliminate the disadvantage that when the upper unit is opened and closed, a document is not fed. Furthermore, as the forward end portion of the first separation piece 21 is formed by a low-friction member, it is possible to prevent the surface of a document from being damaged.
