Matrix printer circuit for operation of mechanical printing elements

摘要

The matrix printer circuit is used to control the mechanical printing elements incorporated in the printing head which is displaced along the printing line, with the control for each printing element providing a printing signal when the printing element has reached a given position in the path of movement to the printing position. Each printing element has an associated delay element for mechanical activation of the printing element in response to the printing signal after a defined delay. Pref. the delay device is provided by a counter which is set to a given value dependent on the printing head velocity by the printing signal, with activation of the printing element upon reaching a final count value.
