PURPOSE: A pattern forming device of a light guide plate is provided to form a pattern which has a fixed interval and fixed length by an instrumental cutter and to produce fast and economically with simple structure and low rate of malfunction, thereby improving the productivity and reliability of product and stably securing a work place, especially by reducing the size of part. CONSTITUTION: A pattern forming device of a light guide plate comprises a cutter(3) which forms a pattern by etching an upper side of the light guide plate; a fixing member(4) which fixes the cutter to be put on perpendicularly and horizontally on a work place, and a pressurization unit which pressurizes the cutter during a fixed time by the predetermined data to etch the plate. The pressurization unit comprises a pressurization member(13) which has a cam side which contacts to one end of the cutter and pressurize, and a reciprocating member(14) which reciprocates the pressurization member in one end of the cutter. |
