Abstract
Together with a scanner device, an air blower is provided above a workpiece, and the air blower exhausts air in the shape of a ring toward the workpiece, the air in a ring shape surrounding an optical axis of a laser beam emitted from the scanner device. A housing of the air blower is formed in a ring shape, a ring-shaped cavity is formed in the housing, an inner ring member is attached to an undersurface of the housing, an outer ring member is attached to an outer peripheral side of the inner ring member, and a ring-shaped exhaust port is formed between the inner ring member and the outer ring member. An exhaust direction of the air is defined by inclination of an outer-peripheral-side end surface of the inner ring member and inclination of an inner-peripheral-side end surface of the outer ring member (FIG.).
