PURPOSE: A cutting device cuts the central part of a panel rapidly, easily and accurately to improve a productivity and reduce a defective proportion. CONSTITUTION: A first and a second air cylinders(35a, 35b) are rotatably installed to face each other on the upper and the lower end of the rear part of a moving working member(31) supported by a first and a second guide bars installed on the front side of a supporting frame(11) and moving by a delivery screw shaft. A first and a second cutters(39a, 39b) to cut the upper and the lower surfaces of a treated panel(A) placed on the upper part of a working panel(12) simultaneously are installed on the front ends of a first and a second driving shaft(38a, 38b) inserted into bearing boxes(37a, 37b) rotatably engaged with the front ends of cylinder rods(36a, 36b) of the first and the second air cylinders(35a, 35b) and rotated by the driving of a driving motor(32). The first and the second cutters(39a, 39b) are approached to and separated from the treated panel(A) as vertically move by the forward and backward movement of the first and the second air cylinders(35a, 35b).
