PURPOSE:To protect a drive IC from the external forces such as a platen and a sheet, by providing projections on a radiation board so as to be corresponding to the sides of the drive IC. CONSTITUTION:Projections 1a are formed on a radiation board 1 corresponding to the sides of an IC 4. When brought into contact with the printing sheet, the projections higher than molds 6 in the IC 4 allow a printing sheet to abut the projections 1a but the molds 6 and thereabouts in the IC. Therefore, with the thermal printer incorporating the thermal head, the drive IC for the thermal head and thereabouts can be protected by the projections 1a. |
