PURPOSE: To constitute a mechanism of a dot head unit in a small size and lightweight at low cost with a good operability to improve a radiation effect of a dot head, in a printing device performing printing while carrying in both directions an impact type dot head mounted on a carrier supported slidably by a guide shaft. CONSTITUTION: A carrier 1 is constituted of a bearing formed of a metal which is rich in thermal conductivity and an elastic member 7 which allows one end to be abutted against the bearing 3 and is rich in the thermal conductivity, the elastic member 7 is abutted elastically against a dot head or a radiator fitted in the dot head 2 and a heat transfer route extending to the bearing 3 from the dot head 2 is formed. |
