A driving device of cutting module for printer used in issuing receipt or chit is provided to increase productivity and to reduce manufacturing cost by avoiding complexity of a manufacturing mold. A fixing blade and a moving blade for cutting a printing paper are faced each other. A worm gear comprises a worm wheel(111) and a worm shaft. The worm wheel is positioned on a first base plate(103). The worm shaft is coupled in the worm wheel, and receives a rotation power from a driving motor. The worm wheel is coupled in a central axis(104) coupled in the first base plate. The moving blade is coupled in a second base plate. A lever plate(120) of a cam shape is arranged on the worm wheel. A first guide hole(121) is vertically formed in a center of the lever plate. The lever plate includes a second guide hole(122) and a lever pin(130). The second guide hole is positioned in a bottom of a large hole(121a) of the first guide hole, and is tilted about the first guide hole. The lever pin is positioned in a top of a small hole(121b) of the first guide hole, and is protruded toward a top direction. A guide pin(140) is installed in a top of the worm wheel. |
