  • Serial printer for typewriters, teleprinters and data processors
    Patent number: 4147438
    Abstract: A serial printer comprising a character carrier having a plurality of flexible leaf springs bearing characters on the extremities thereof. A desired character is selected by positioning the corresponding leaf spring to a printing position. A pushing mechanism exerts pressure against the leaf spring in the printing position to effect a controlled motion thereof such that the character meets the paper at a low velocity instead of from acquired kinetic energy thereby resulting in noiseless printing.
