ABSTRACT:
A paper feed mechanism for feeding fan-fold paper into a printer, a typewriter, or the like has a drive roller, an idler roller, and a pin belt trained around the drive and idler rollers and having a series of pins for engaging in perforations of the fan-fold paper. The fan-fold paper is guided by first and second paper holders that are angularly supported on a frame. The first paper roller is of an arcuate shape and extending along an outer periphery of the drive roller. The first paper roller is angularly movably supported on the second paper roller. The second paper roller extends along a straight portion of the pin belt between the drive and idler rollers.
