Definitions

  • This invention relates to an impact printer for selectively printing information directly onto a print medium moving past a print location.
  • the 3,915,276 patent is referenced because it shows an impact printer with print elements on a rotatable belt but uses a ribbon and does not print in color.
  • the 3,672,297 patent is of the same type as the 3,915,276 reference.
  • the 4,056,183 patent shows a matrix printer using a rotatable inked platen and the 4,069,755 patent shows a matrix wire printer using a rotatable ink stamp without a ribbon.
  • the 4,191,104 patent shows a printer with a rotating belt with print elements thereon.
  • the 4,194,846 patent shows an impact matrix printer wherein ink from a reservoir is directed to a printing element. No ribbon is used and no rotatable belt is employed.
  • An advantage of the present invention is to provide an impact printer that does not require a ribbon.
  • Another advantage of the present invention is to provide a ribbonless impact printer that prints in color.
  • a further advantage of the present invention is to provide a ribbonless impact color printer that prints in an all points addressable matrix mode.
  • Still another advantage of the present invention is to provide an all-points addressable ribbonless impact matrix color printer that incorporates ball-point print elements.
  • Still another advantage of the present invention is to provide an all-points addressable ribbonless impact matrix color printer that incorporates ball-point print elements on a rotating belt.
  • Still another advantage of the present invention is to provide an all-points addressable ribbonless impact matrix color printer that incorporates ball-point print elements on a rotating cylinder.
  • FIGS. 1, 2 and 3 illustrate side, top and front views respectively, of a ribbonless, all-points addressable color impact matrix printer using ink elements such as ball-point elements mounted on a rotatable belt.
  • ball-point print elements 10 are mounted, for example molded, onto rotatable belt 12 with a predetermined spacing between the print elements.
  • Belt 12 is rotated continuously by drive pulley 26.
  • Print hammers 14 are placed behind paper 16 (FIG. 3) which is moved by paper drive mechanism 20.
  • Each ball-point print element 10 has an ink reservoir 18 (FIG. 3) or alternatively, several print elements may share one common ink reservoir separated into different chambers, each containing different color ink.
  • the ball-point print elements may be standard ball pen tips.
  • the resultant printing format on paper 16 is a function of the speed of print belt 12 and paper 16, the spacing between print elements 10, and the width and repetition rate of print hammers 14.
  • a line printer of 380 lines per minute is achieved.
  • faster printing speed can be achieved by mounting the ball-point print elements onto the surface of a rotating cylinder as shown in FIG. 4.
  • the structure of FIG. 4, as in FIGS. 1, 2 and 3, includes ball-point print elements 10, print hammers 14, paper 16, ink compartments 18, paper drive mechanism 20, and a shield or platen structure 24.
  • the ball-point print elements 10 are mounted on the periphery of cylinder 28 and the ink reservoirs are located inside cylinder 28.
  • the print elements 10 now move in the same direction as paper 16 rather than transversely as shown in FIGS. 1, 2 and 3.
  • a vertical print element spacing of 0.05 inches on a 3.0 inch diameter cylinder rotating at 320 rpm a printing speed of 1200 lines per minute can be achieved with a 1 m second hammer repetition rate.
  • FIG. 5 shows a number of groups of ball-point tips arranged in a helical configuration, in sets of five.
  • the width of the hammer 14, is as wide as the ball-point set.
  • a horizontal line composed of five dots is described.
  • the printer may be embodied using either a rotating flexible belt or a rotating cylinder.
