ABSTRACT:
A pin wheel feed mechanism for transporting documents having feed perforations along the marginal edges thereof. The mechanism includes a pair of symetrically constructed guide frames, each adapted for use on either marginal edge of the feeding document. A pin wheel is rotatably housed in each guide frame and includes a plurality of equiangularly spaced pins which project radially from the surface of each wheel for feeding the document. A notch is provided between each pair of adjacent pins to accommodate warps in the marginal edges of the document to insure positive feed.
