Claims
- 1. A wire dot printer using a plurality of print wires to print on a printing medium, comprising:
- a print head unit;
- a guide member defining a wire nose, said guide member being mounted on one end of said print head unit;
- a wire guide member mounted proximate one end of said guide member and including a plurality of openings for guiding said print wires; and
- a supporting member mounted on said guide member on said one end thereof having a first surface for coupling said supporting member to said printer, said supporting member having an end surface having an opening therein corresponding in size and shape to that of the wire guide member, said wire guide member being positioned and supported by said opening in said supporting member,
- said guide member including a plurality of spaced wire guide plates supported on said wire nose of said guide member, said wire guide plates being disposed essentially parallel to said wire guide member, said wire guide plates and wire guide member each having holes aligned therein through which said print wires extend for guiding said print wires.
- 2. A print wire guide device for a wire dot printer, wherein a first level of inner print wires and a second level of outer print wires are selectively driven in a direction extending essentially normal to said wire guide device, said wire guide device comprising:
- a member having a side wall for defining a passageway for receiving said wires;
- said passageway terminating in a bottom, said bottom having an inner row of through-holes and an outer row of through-holes therein, said first level of inner print wires being received in said inner row of through-holes, said second level of outer print wires being received in said outer row of through-holes;
- said inner row of through-holes and said outer row of through-holes being arranged in alternating fashion in a curved path, said outer through-holes being on the outer side of said path and said inner through-holes being on the inner side of said path;
- said side wall having concave wire guide grooves formed in portions of said side wall only corresponding to respective through-holes of said outer row, said second level of outer print wires being guided by said concave wire guide grooves only to said outer through-holes.
- 3. The print wire guide device of claim 2, wherein said passageway has an inclined, stepped portion.
- 4. The print wire guide device of claim 3, further comprising a wire driving means coupled to said wire guide device, said wire driving means being for selectively driving said wires.
- 5. The print wire guide device of claim 4 wherein said wire driving means comprises a first section for driving said first level of inner print wires and a second section for driving said second level of outer print wires, said inner through-holes guiding said first level of inner print wires and said outer through-holes guiding said second level of outer print wires.
- 6. The print wire guide device of claim 4, wherein said first and second sections are stacked along the axial direction of the device.
