ABSTRACT:
A laser processing device includes a Z stage movable in the up and down directions with respect to a XY stage movable in the X, Y directions on which an object to be processed is provided. The surface of the object to be processed is image-sensed by a CCD camera through a lens of an electrically-driven revolver attached to the Z stage, which is projected in a monitor. When a defect of the object is displayed in the monitor, a laser beam is radiated to a defective portion of the object from a laser head provided in the Z stage and the defective portion is removed.
