ABSTRACT:
A dot matrix printer having a plurality of hammers on a hammerbank with a counterbalance for the hammerbank in adjacent parallel relationship to the hammerbank. The hammerbank and counterbalance are driven by a first crank arm connected to the hammerbank and a second crank arm connected to the counterbalance with looped circular portions having bearing surfaces for moving the crank arms in opposite relationship to each other. A single shaft with two eccentrics, each respectively in the bearing surfaces turns the two crank arms. The crank arms are in close parallel relationship to each other and close proximity to the hammerbank and counterbalance. The single shaft is connected to a motor for driving the hammerbank and counterbalance, and is formed with a stator having coils with a magnetic ring formed as a rotor portion surrounding the stator, and a flywheel surrounding and connected to the magnetic rotor ring.
