Definitions

  • the present invention relates to impact serial printers used in data processing systems, and more particularly to the mechanical structure of such printers with reference to the noise produced during the printing.
  • FR - A - 2 280 511 it has been disclosed a way of reducing noise by providing a printer with a hollow cylindrical platen, the platen cavity being filled with noise deadening material such as small lead or steel balls.
  • the platen shaft is further mounted to the printer frame through the interposition of rubber bushing.
  • a noise reduction is therefore obtained by decoupling, as regards vibration diffusion, the mechanical elements, which constitute the main noise source, the one from the other and from the secondary element that is the frame.
  • the mechanical structure of a printer includes a metallic frame formed by a bottom 5 and at least two sides 2, 3.
  • front bar 6 is therefore engaged in the two grooves of side plate 3 and of side plate 2 respectively, through bushes 9, 10 and rear bar 7 is engaged in the other two grooves of side plate 3 and of side plate 2 respectively, through bushes 12 and 11. Both couples of bushes 10, 11 and 8, 9 are then clamped to side plates 2 and 3 respectively through clamping plates 13, 12.
  • the parallelism between bars 6 and 7 is essential for a proper advancement of the printing head carriage; the parallelism between platen 16 and bar 7 is essential for uniform printing.
  • platen 16 ends are not restrained to side plates 2 and 3 of the metallic frame (solution adopted in the prior art) but platen 16 together with bars 6 and 7, thanks to arms 14 and 15 form a unitary member connected to the metallic frame only through bushes 8, 9, 10, 11.
