PURPOSE: A cutter for a light guide plate pattern forming apparatus is provided to obtain uniform brightness by forming a groove of conical shape, thereby increasing productivity and improving the reliability of quality. CONSTITUTION: A cutter blade of horn shape is formed at the end portion of a cutter rod(4). A fixing body(6) has a plurality of penetration holes(5). The fixing body is comprised of an elastic body having elasticity. The plurality of penetration holes exposes a cutter blade of the cutter rod to outside. The plurality of penetration holes is arranged as a grid pattern. The fixing body comprises a temperature sensor and a heating unit. The temperature sensor senses temperature. The heating unit emits heat by receiving a power source controlled by a controller. The controller calculates temperature data sensed by the temperature sensor and receives the power source from a power supply unit. |
