Title: Thermal head
Inventor: ENDO TAKAFUMI
IPC: B41J2/335
Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To ensure the linearity of a group of heat resistance bodies, and thereby prevent the occurrence of printing unevenness by providing thermal deformation preventing means for preventing the thermal deformation of a heat substrate set on the radiation substrate. SOLUTION: An adhesive material 10 consisting of thermosetting epoxy resin is used for adhering a heat substrate 3 and radiation plate 1. As a result, the radiation plate 1 and substrate 3 are adhered and integrated with each other firmly. Thus, the radiation plate 1 formed of polycarbonate resin having a smaller thermal coefficient than the substrate 3 is affected by heat contraction of the radiation plate 1, resulting in the lowering of a thermal contraction rate. Accordingly, even in the event where force causing arcuate curvature deformation is applied on the substrate 3 due to the difference of the thermal contraction rate between the glass epoxy resin made wiring plate 6 and the ceramics made substrate 3 by cooling of the print wiring substrate 6 and substrate 3, the linearity of a group of the heat resistance bodies 4 is ensured on the substrate 3 because of the substrate 3 strongly integrated with the radiation plate 1 having a smaller thermal contraction rate than the substrate 3 by an adhesive material 10.
