PROBLEM TO BE SOLVED: To prevent contamination of flame or recording paper by preventing the dripping of ink from the injection head of ink jet recording head through a simple structure. SOLUTION: Spreading grooves 36 having capillary action are made longitudinally and laterally in the outer surface of a protective member 35 surrounding the outer circumferential side of a recording head 32 having an injection nozzle between the surface facing a recording paper and the lower surface of protective member at the lower side of recording head and in the outer surface at the side part. The spreading grooves 36 spreads an ink dripped from the injection nozzle or wiped by means of a wiper longitudinally and laterally thus drying up the ink quickly. |
