Abstract

The shuttle print head of a matrix printer carries a plurality of printing elements and is supported by leaf springs on the printer frame. The print head is fixed to the movable core of a linear electric motor whose driving coil is also supported on the frame by leaf springs. The masses of the print head array and coil are made equal to form a balanced mass/spring system having a natural resonant frequency of oscillation of sinusoidal motion. The resonant frequency is chosen to correspond to a desired print rate. The drive coil is energized with alternating current at the resonant frequency in order to maintain the si­ nusoidal oscillation of the print head array at the required ampli­ tude of oscillation. Selective energization of the printing elements effects selective printing of indicia at equal space column locations.
