Generally, support systems for conventional wire matrix print head assemblies of the type disclosed in U.S. Pat. No. 3,929,214, U.S. Pat. and a pair of relatively narrow width centrally spaced intermediate wire support members disposed at widely centrally spaced intervals between the print end passageway and the print end passage. The assembly of wire members during the manufacture of such printhead assemblies and the disassembly and replacement of wire members for service, maintenance, and repair are tedious, expensive, and time consuming. This is because the wire members are arcuate in the assembled state, requiring hand alignment from passage to passage, thereby eliminating not only intermediate passages but also expensive, brittle ruby or ceramic materials that require careful installation. This is because it requires that a support member consisting of a wire be inserted into each of the individual wire passageways, which also includes the print edge support passageway, which is typically the case. Furthermore, the wire members must be individually inserted in a predetermined order and, as a result, must be removed in a predetermined order;
In order to repair or replace a particular wire member, the excess wire member must also be removed. The normal assembly procedure is to use special fine tweezers to grasp the ends of the wire members and position them relative to each passageway after the first armature end pass and before entering each passageway, so that the central axis of the wire member exercise will be interrupted.

One attempt to solve these problems has been to use a continuous straw-like tube of constant diameter for each wire member, much larger than its diameter, with each tube bowed between its end passages. It is installed in the same position. Such tubes have various problems. To name a few, the axial spacing and position of intermediate support sections (which are absolutely necessary for performance) cannot be maintained properly, and the circumferential support of wire members at critical locations cannot be maintained properly. It cannot be properly maintained and, furthermore, this tubular passageway tends to create capillary action during reciprocating movement of the wire member, causing ink to flow into the passageway. Ink within such passageways interferes with continued satisfactory performance of the device.

When the coil device 130 is energized, a magnetic force acts on the radially outermost portion 164 of the armature, causing these portions to rotate about the first pivot device 231, thereby causing a force on the pole end face 137a. Move toward the destination. When the armature is parallel to the end surface 137a of the pole, the first pivot device is inactive and the second pivot device provided by the radially outermost edge surface 137b (FIG. 13) of the outer pole is activated. The actuated state allows further rotation of the armature while increasing the radial length from the pivot device to the armature drive head 55. The first O-ring member 74 is resiliently compressed during rotation from the non-printing position to the printing position, resulting in enhanced frequency response with some loss of armature kinetic energy. a spring member 53 corresponding to the wire member 54 when the coil member is deenergized;
The repulsive force of the colliding paper of the wire member 54 and the compressive force of the O-ring member 74 combine to quickly return the armature member to the non-printing position, while at the same time the residual repulsive force of the spring member 53 and the paper causes the wire member 54 to
quickly return to non-printing position. Armature overtravel during return movement is limited by the resilient compressive engagement with member 182, substantially eliminating rebound and noise during actuation. Note that the arrangement is such that there is little resistance until the return movement is nearly complete. It should also be noted that upon impact of the wire member 54 with the paper, the second pivot device is arranged so that maximum leverage is utilized both during printing and at the beginning of the return movement. A single centric connection provided by a threaded fastener 17 through an elastic member between two relatively rigid and precisely positioned parts allows the spacing between the armature member and the pole to be very closely spaced. Allows fine and accurate adjustment.
