Abstract

Print wires 10 are driven by nested piezoelectric bending elements 11 against a ribbon 12 to print dots or picture elements 13 on paper 14. Shuttle bar 15 translates the impact end of wires 10 through a horizontal stroke 16. This shuttle motion, in combination with the motion of a stepper motor 17, distributes the printing positions of dots 13 throughout a raster area 18. Shuttle 15 is displaced by piezoelectric bending element 19 which, together with stepper motor 17, is controlled by circuitry 20 to define the placement of dots in raster 18.
