Abstract
A multiple stylus print head, e.g. for printing a document in a facsimile system, has at least two parallel lines of styluses with the styluses being offset from one line to the next. Each line of styluses is built up from several tiers of interdigitated conductor pins (C) having tips that constitute the styluses per se. The tiers of pins are held together by respective strips of insulating material (7) forming comb-like structures which are then stacked together in such a manner that the combs fan out from the line of styluses. A plurality of groups (G.sub.1, G.sub.2) of stylus line forming comb structures are stacked together into a single stack.
