Automatic Paper Loading Assembly for Point Of Sale Printer

       Disclosed is a mechanism that facilitates the loading of
paper in a point-of-sale printer.  This system provides automatic
loading and dual-use of the paper feed roll.

      The automatic paper-loading system consists of a Paper Feed
Roller (refer to Figs. 1 and 2) which is mounted to the Frame.  The
Roller Holder contains the Paper Load Roller and the Pressure Roller.
Also mounted on the Roller Holder is the Toggle Spring.  The Toggle
Spring provides the force between the Feed Roller and the Paper Load
Roller or between the Feed Roller and the Pressure Roller depending
on the position of the Handle/Roller Holder.

      Paper is loaded by inserting the leading edge of the paper into
the rear throat of the assembly as shown in Fig. 1.  When the leading
edge of the paper is below the Feed Roller, the Roller Holder is
manually rotated by pulling the Handle forward (see Fig. 2).  As the
Roller Holder pivots, the Toggle Spring rotates about its pivot on
the Frame.  The Toggle Spring now provides force between the Feed
Roller and the Paper Load Roller.  The Feed Roller is driven by a
motor through a gear train and the paper is "pushed" through the
paper path.

      After paper is loaded, the handle is pushed back (see Fig. 3)
and the Roller Holder toggles to provide force between the Feed
Roller and the Pressure Roller.  Paper can now be fed for normal
printing by driving the Feed Roller...
