Abstract

The figure illustrates a top plan view of a selective indicia printer. The indicia to be printed is embossed, stamped, or etched on a print roller or drum 1 which is mounted on an arm 2 via a bearing 3. Arm 2 is affixed to a pivot 4 driven by rotary solenoid 5 which is mounted on a fixed mount 6. Mount 6 moves with a wire-matrix printing head 7 back and forth in an arcuate path, illustrated by the arrows, with the wire matrix print head 7 pivoting about its central pivot 8.

Selective Indicia Printer

The figure illustrates a top plan view of a selective indicia printer. The indicia to be printed is embossed, stamped, or etched on a print roller or drum 1 which is mounted on an arm 2 via a bearing 3. Arm 2 is affixed to a pivot 4 driven by rotary solenoid 5 which is mounted on a fixed mount 6. Mount 6 moves with a wire-matrix printing head 7 back and forth in an arcuate path, illustrated by the arrows, with the wire matrix print head 7 pivoting about its central pivot 8.

One or more arcuate platens 9 are utilized to store a media to be marked upon, by either the indicia drum 1 or the wire matrix print head 7. Rotary solenoid 5 has a torsion spring integral therewith, which normally holds arm 2 pivoted back out of engagement with platens 9.

In order to ink the indicia drum 1, an inking pad 10 of arcuate form supplied from a suitable wick and reservoir 11 and 12, respectively, is provided. This pad inks the surface of drum 1 when solenoid 5 is energized to pivot arm 2 and bring the drum 1 into contact with inking pad 10, during the course of travel of the pivoting print head 7. A stop pin 13 is mounted on the drum 1 to interact with arm 2 and a torsion spring, not shown, acts to return drum 1 to a home position with stop pin 13 engaging arm 2.

When it is desired to imprint the indicia carried on drum 1, solenoid 5 is energized during travel of print head 7 in the counterclockwise direction to bring drum 1 into contact with either platen...
