Abstract: A recording element for a matrix printer having an armature which is capable of movement relative to a casing under spring action by means of electric energization and to which a recording stylus is secured. The restoring spring surrounding the stylus is centered in the element in that its two end parts each comprise a plurality of closely wound turns. The spring part intermediate the end parts provides the spring action. Thus wear of the spring and the stylus due to rubbing contact is avoided.

Abstract: A matrix printer comprising a printing head which can be moved to and from along a record carrier in a direction parallel to a printing line direction. The printing head is provided with straight recording pins which are arranged to be mutually parallel at equal distances from each other. The printing ends of the recording pins are situated in one line parallel to the printing line direction. Between the printing head and the record carrier an ink ribbon is arranged which is intermittently displaced, together with the record carrier, in a direction transverse to the movement direction of the printing head. The ink ribbon wear and reduction of the coloring agent are thus spread over the full width of the ink ribbon.

Abstract: The invention relates to a matrix printer having a bar-shaped member which is movable along a recording sheet and carries a plurality of straight mutually parallel recording styli which are mounted in a holder and are adapted to be moved perpendicularly to the recording sheet by means of electric energization, and means for moving the recording sheet in a direction transverse to the direction of movement of the bar-shaped member.
