Abstract

In the print head for a wire-matrix printer application requiring a plurality of print wires, the print-wire actuator magnets (for each half of the symmetrical head) are alternately located radially on two concentric substantially semi-circles. This design minimizes the space required and optimizes the print wire path.

Wire-matrix Print Head

In the print head for a wire-matrix printer application requiring a plurality of print wires, the print-wire actuator magnets (for each half of the symmetrical head) are alternately located radially on two concentric substantially semi-circles. This design minimizes the space required and optimizes the print wire path.

Fig 1 shows the application-dependent arrangement of 24 print wires at the front plate of the present embodiment. It is seen that there are twelve print wires 2, on each side of the head, grouped in two staggered columns 4 and 5 of six wires each. Fig 2 shows the staggered semi-circular arrangement of the actuators 1 and the actuator ends of the print wires 2 for one half of the head. It is seen that in order to keep the actuator armatures and levers the same for all positions, the contact points of levers 3, and wires 2, are also grouped in two semi- circles 6 and 7, matching the front plate groupings 4 and 5, respectively, shown in Fig 1. It is apparent that this arrangement optimizes print-wire paths by maintaining maximum spa between the wires.
