Printer

Abstract

Abstract PURPOSE: To enable an easy micro-tuning of a gap between a platen and a head, by a method wherein, in a printer which moves in parallel the print head against the platen, an eccentric bush is placed at a portion where a guide shaft and a device frame are mounted. CONSTITUTION: A guide shaft 5, which moves in parallel a carrier 4 secured on a print head 3, is mounted at a frame 1 through the medium of an eccentric bush 8. Said eccentric bush has a perforation 9, into which the guide shaft 5 is inserted at a portion being eccentric to a central line C of the bush, and is positioned so that it can rotate against the frame 1. A detent sheet spring 10 and an operating lever 11 are fixed by means of a screw at a outer end surface of the eccentric bush 8. A knob 14 of said operating lever rotates in the direction A' or B', and a detent projection 12 on the sheet spring 10 rotating in acompany with the knob is hooked in concavities 13aW13g provided in the frame 1 to adjust a position of the print head 3.
