Abstract
Plural guide holes are arranged in a matrix form in a wire guide. Plural print drivers are circularly arranged in plural layers for first print drivers belonging to a layer near to the wire guide and for second print drivers belonging to a layer far from the wire guide. A print wire is provided at each print driver so as to project end thereof from the guide hole of the wire guide when driven. The print wires formed at the first print drivers are inserted in the guide holes of lines located at the edge formed in the wire guide. On the other hand, the print wires formed at the second print drivers are inserted in the guide holes of lines located at the center of the wire guide.
Claims11
A wire dot print head comprising:
- a wire guide having guide holes arranged in a matrix;
- a plurality of print drivers circularly arranged in plural layers including a first layer nearest to said wire guide and a second layer farthest from said wire guide;
- and
- a plurality of print wires provided respectively to first print drivers of said first layer nearest to said wire guide and to second print drivers of said second layer farthest from said wire guide, ends thereof projecting from said guide holes of said wire guide when driven by said print drivers;
