Abstract
The matrix head (1) of a matrix printer is guided close to the printing site (2) on a round bar (7) by means of profiled rollers (8) absorbing the reactive force during printing and being fixedly mounted at the matrix head (1) and by means of guide rollers (9) absorbing the force of gravity of the matrix head (1) and being resiliently mounted at this head, and is slidingly guided, at the head end facing away from the printing site (2), on a rail (15). A cord drive serves for displacing the matrix head (1), this cord drive comprising a cord (31, 32, 33, 34, 35) guided over a cord pulley (17) at the matrix head (1) and over further cord pulleys (19, 23, 24) and over a driving pulley (26), the ends (29, 30) of this cord being fixedly attached beside the ends of the round bar (7). Thereby the matrix printer can be constructed in a compact and lightweight fashion and can be operated with accuracy even in case of strong vibrations.
