PURPOSE:To restrain a temperature rise of a print head and improve the durability and safety at a low cost by a method wherein a heat conductive material is tightly attached between the print head and a carrier to which the print head is mounted so that heat generated due to printing action easily escapes toward the carrier side. CONSTITUTION:A heat conductive material 2 is formed into a shape that fits a gap between a print head 1 and a carrier 3, and the print head 1 is mounted on the carrier 3 with the heat conductive material 2 inserted between the print head 1 and the carrier 3. Therefore, the amount of heat transferred from the print head 1 to the carrier 3 increases compared with former devices and much heat is taken away from the print head 1 in addition to the amount of heat released into the atmosphere, so that a restraint effect of temperature rise of the head 1 can be expected. When the heat conductive material 2 is made of elastic material, the effect of changes in size due to thermal expansion at high temperature can be also avoided. |
