ABSTRACT:
The recording system has a plurality of recording elements pivotally mounted to make marks in a direction substantially perpendicular to the direction of transport of the record carrier receiving the marks. Each recording element has a rigid electrically conductive L-shaped supporting member and an electrode mounted on the supporting member. The supporting members are mounted in recesses in a base of an electrically insulating structure. Specifically one leg of each supporting member has two supporting edges separated by a recess. The two edges are accommodated in corresponding openings in the base. An eccentric drives a drive arm having a plurality of plugs. A spring keeps the supporting member of each recording element in contact with the corresponding plug throughout the pivoting of the recording element.
