WIRE DOT PRINT HEAD AND MANUFACTURE THEREOF

摘要

PROBLEM TO BE SOLVED: To make driving characteristics of print units identical, to lessen also the kinds of components and to simplify a control circuit. SOLUTION: This print head has a plurality of print units 12 and 13 which are stacked in a multistage manner in disposition and equipped with armatures 26 and 56, print wires 27 and 57 and electromagnets 35 and 65 respectively. The respective print wires 27 and 57 of the print units 12 and 13 are disposed in such a manner that they pierce wire guides 31-33 of the print unit 12 disposed in the most proximity to a print medium and the print wire 57 of the print unit 13 is made to project by a set distanceΔx from the print wire 27 of the print unit 12. The print wires 27 and 57 reach a printing peak at the same timing.
