Claims

[Scope of utility model registration request]

In a laser processing apparatus that includes a condensing lens that condenses a laser beam irradiated from a laser oscillator and processes a workpiece with the laser beam that is condensed by the condensing lens, the laser beam irradiated from the laser oscillator is A plurality of prisms that give a deflection angle to the laser beam are placed in the direction of the laser optical axis.
Further, the prisms are arranged rotatably around the laser optical axis, and a gear is attached to each prism, and the angle formed by the apex direction of each of the prisms is adjusted by meshing across the gears and rotating. A pair of variable deflection angle prisms equipped with adjustment teeth are provided, and each of the variable deflection angle prisms is supported rotatably in the laser optical axis direction and around the laser optical axis, so that the deflection angle variable prisms are rotated in opposite directions around the laser optical axis. 1. A laser processing apparatus, characterized in that a scanning means is provided which rotates at a constant speed to scan a laser beam focused by the focusing lens in a straight line.
