Abstract
A receipt cutting mechanism includes a round knife or blade which is positively and rotatably driven and which engages with a fixed knife edge as the round knife travels across the printer on a driven carriage. The positive drive includes a gear cluster arrangement operated by a toothed belt which is stretched across the printer. The round knife is maintained in engagement with the fixed knife edge by means of a torsion spring tending to rotate the knife and its support in one direction.
