Abstract
A resilient friction pad is pushed by a spring against a conveying roller for feeding paper automatically in a printer. The friction pad is placed in a recess at the end of the paper tray. A flat auxiliary spring may be used to share the pressure of a heavy paper load and to prevent the separation of the resilient friction pad and the conveying roller. A support block may be placed underneath the resilient friction pad to prevent sagging of the resilient friction pad. A corrugated arm may be inserted between the push-up spring and the resilient friction pad to provide wider contact between the resilient friction pad and the conveying roller. Two springboards, one wider than the other, are located at the tail end of the resilient friction pad, one to lift to paper tray when the paper stack is light and the other to depress the paper stack so that paper in the upper section of the remaining paper stack does not push the paper being fed so hard that more than one sheet of paper are fed.
