PURPOSE: A stamping roller for a light guide plate pattern forming apparatus is provided to prevent a fault of a light guide plate caused by the creasing of a stamp pad by tightly stretching the thermally expanded stamp pad. CONSTITUTION: A stamping roller for a light guide plate pattern forming apparatus comprises a roller member(10) in which a plurality of heaters(11) are embedded and a stamp pad(20) which is pressed to a contact surface of the roller member. One end(21) or/and the other end(22) of the stamp pad are fixed to the roller member via an elastic clamp(40) and elastically pulled by the elastic clamp. Therefore, the stamp pad, which is expanded by heat, is maintained tight without creasing. |
