PURPOSE:To provide a piezoelectric device driving print head which makes only a little noise and can be obtained at a low cost by effectively reducing noises to be generated by the vibration of the piezoelectric device driving print head. CONSTITUTION:Spaces between support frames 10 which support a print unit 4 are filled with a heat conductive material 30 having a high hardness and spaces between the support frames 10 and a radiating cover 3 are filled with a gel-like heat conductive material 31, so that the movements of the support frames 10 are interrupted and the vibration becomes lower. The vibration from the support frames 10 is insulated by the gel-like heat conductive material 31, so that it will not be transmitted to the radiating cover 3. |
