Abstract
An integral frame type paper feeder in which perforated paper is fed by a pin-carrying feed belt set in a main frame by a driving sprocket. The paper feeder has a pair of sub-frames for assembling the feed belt and driving sprocket in a sub-assembly, and a main frame consisting of a pair of opposed side plates spaced from each other at a predetermined distance, and to which the sub-frames are fixed, and an upper plate the upper surface of which constitutes a paper feed surface. The upper plate has a feed belt moving bore which extends in the direction in which the perforated paper is fed, and which causes the portion of the feed belt on which the perforated paper is being fed to be aligned with the paper feed surface. The two sub-frames, and the feed belt and the driving sprocket are combined with the sub-frames into a driving assembly, and this is fitted between the side plates of the main frame.
