ドの取付構造。[Claims for Utility Model Registration] (1) The printing head is fixed to a bracket via a heat sink, and this bracket is divided into three parts and attached to the center part and the end part of the printing head, respectively. A printing head mounting structure characterized in that a heat radiation hole is formed in a divided central bracket fixed to a print head so as to prevent the difference in thermal expansion between the heat radiation plate and the bracket. (2) The print head is fixed to a bracket via a heat sink, and a screw mounting hole is formed at the end of the bracket, and the screw mounting hole has a hole that is longer than the height of the end of the bracket and has a hole wall. The heat dissipation due to thermal expansion is achieved by inserting a sleeve that sets an appropriate gap between the bracket and abutting the lower surface of the sleeve against the heat dissipation plate, and fixing the bracket to the heat dissipation plate by means of a fastening means via the sleeve. A printing head mounting structure characterized by a plate that can be freely expanded and contracted in the longitudinal direction.
