Abstract

In a paper-insertion system for a typewriter (see figure), a sheet or pack of paper P is arranged between a paper guide 12 and a platen 14 soas to rest against a set of fingers 10. A phasing bail 16 is then rotated in a counterclockwise direction (as viewed) to drive a set of rear rollers 18 to clamp the paper P against the platen 14. Further rotation of phasing bail 16 transfers motion through a linkage 20 to drive the fingers 10 and a set of front rollers 22 away from the platen 14. At this point in the insertion operation, platen 14 is rotated by indexing means (not shown) in a clockwise direction,. Such rotation pulls the paper P into the gap between the platen 14 and the front rollers 22.
