DEFINITION

Classification: 400/124.01

Character formation by impact (e.g., wire matrix):

(under subclass 118.2) Subject matter wherein the character* symbol is formed on the record-medium by percussing two or more discrete elements (i.e., impact members) arranged in a group by use of an actuator directly or indirectly against the record-medium*.

(1) Note. The discrete elements are arranged into the configuration of a selected character*, the same or different discrete elements being selectable to arrange such elements into the configuration of a different selected character*, wherein each of the discrete elements is a member that is movable from a rest position where it does not effect imprinting to an active position where it effects printing, and wherein the configuration of a selected character* symbol is formed by moving selected members from a rest position to an active position by energization of actuators in the printhead.
