Abstract

The paper guide illustrated in the figure is fabricated of two interleaved, welded wire pieces that slide on each other and maintain a common surface to guide the paper while it is being stacked. When the paper tray is in its lowest position, the rear guide is fully extended, thus supporting the paper stack. To gain access to the paper load area (which shares space with the output stack), the paper tray is moved to its uppermost position. This action causes the rear guide to retract upward, providing access to the load area. This provides a means of sharing space between the paper supply stack and the paper output stack in a continuous forms printer.

Variable Length Paper Guide for a Continuous Forms Printer

The paper guide illustrated in the figure is fabricated of two interleaved, welded wire pieces that slide on each other and maintain a common surface to guide the paper while it is being stacked. When the paper tray is in its lowest position, the rear guide is fully extended, thus supporting the paper stack. To gain access to the paper load area (which shares space with the output stack), the paper tray is moved to its uppermost position. This action causes the rear guide to retract upward, providing access to the load area. This provides a means of sharing space between the paper supply stack and the paper output stack in a continuous forms printer.

The rear paper guide and tray are shown in the figure. The rear paper guide consists of a two-piece welded wire assembly. One piece is the stationary part 11 which is fastened to the walls of the paper-handling tray of the continuous forms printer at the eyelets 15 by standard mechanical fasteners. The other piece is the moveable part 12 of the guide which is free to slide vertically. The two pieces are nested together so that motion of the moveable guide is constrained by the stationary guide. The two pieces are held together by two helical extension springs 14. The guide remains in this configuration until the paper tray 13 moves sufficiently far downward for the four hooks 17 on the paper tray to latch onto a horizontal wire 18 on the moveable guide.
