  • Wire matrix printer with damping means
    Patent number: 4613243
    Abstract: Electromagnetic printing group for a dot matrix printer where the armature movement towards the rest position isdamped by a counterarmature interposed between the armature and a resilient element defining the rest position so that the air cushion interposed between counterarmature and armature provides a first damping action followed by the damping caused by the ballistic impact between armature and counterarmature and finally by the resilient damping of the residual energy of the armature and counterarmature.

  • Mosaic printing head
    Patent number: 4367962
    Abstract: A mosaic printing head for use in a computer printer includes a needle guiding assembly and an electromagnet assembly for activating the needles. The printer head utilizes a unique design to provide for simple and fast adjustment of the position of each printing needle while eliminating any effect on the adjustment because of vibrations occurring during the printing. This design allows the needle stroke to be adjusted so as to achieve very high speed printing operation.
