摘要： A matrix head wire print position shift apparatus which includes a plurality of longitudinally movable print wires (42) which are disposed in guides (56, 60, 64). One of the guides (64) supports the printing ends of the wires (62) and is transversely shiftable between a first print position and a second print position by a shiftable support (68). In the first print position the print wires are selectably operable to print characters defined by a first set of adjacent substantially tangential circularly shaped dots. In the second print position the wire print devices are selectably operable to enhance printing of the characters with a second set of overlapping dots which are offset by one-half dot space from the first set. The shifting device (70, 94, 110) is located within the print wire housing (10).

摘要： In a wire dot print head (1) having print wires (3) extending through an opening of a guide nose (20), the guide nose comprises two halves (21). The print head may further comprise a wire guide (51) which is fitted in the guide nose (20) and through which the print wires (3) extend, and the wire guide may be clamped by the two halves. In another embodiment, the half members have abutting surfaces (117a) provided with semi-circular grooves (118a), which when the guide nose halves are assembled, form guide holes in which the print wires are slidably supported. The use of the two halves facilitates assembly of the print head and reduces noise.

摘要： A guide device for the needles of a print head of a dot matrix printer is described, of the type in which the needles are supported by a matrix and by at least one other guide element, as well as the process for its production; the principle character­istic of this device lies in the fact that at least the matrix (4) is formed by one or more thin superimposed plates (11) provided with guide holes (12) for the needles formed by photo-etching; if more than one, such plates are glued together with their holes offset.
