FIG. 1 is a diagram showing an example of a conventional pattern projection type laser processing apparatus. That is, a laser beam emitted from a laser oscillator 1 enters a concave lens 2, is expanded, is made into parallel light by a collimating lens 3, passes through an original printing image 4, and enters a projection lens 5. The original printing image 4, the projection lens 5, and the workpiece are arranged such that the processed surfaces of the original printing image 4 and the workpiece 6 are at conjugate image positions with respect to the projection lens 5. Therefore, the pattern of the printing original 4 is reduced and transferred onto the processing surface of the workpiece 6 by the laser light emitted from the laser oscillator 1.

FIG. 2 is a diagram showing an example of a conventional projection type laser processing apparatus with variable processing width. That is, the laser light emitted from the laser oscillator 1 enters the movable aperture slit 7, and the laser light that passes through this enters the projection lens 5. The projection lens 5 is arranged so that the image of the movable aperture slit 7 forms a conjugate image on the machined surface of the workpiece 6, and the reduced pattern of the aperture slit 7 is transferred to the machined surface of the workpiece 6. .
In this device, since the width of the opening slit 7 can be changed, it is possible to set the opening slit 7 to a desired width and process it.

However, the laser beam formed into a rectangular shape by the surface of the first aperture slit 11 passes through the second aperture slit 1.
It is projected onto three planes, where it is again additionally formed.
Then, this final shape is reduced and projected onto the workpiece 6 by the processing projection lens 5, and the workpiece 6 is processed into the final shape.

d is additionally formed by the surface of the second opening slit 13 and the final patterns 7a, 17b, 17c, 1
It became possible to obtain fairly free shapes like 7d. In particular, c is an example in which the rectangular pattern 16c obtained by the first rectangular opening slit 11 is additionally formed in an X shape by the second chevron opening slit 17c, and the slit of the required shape is formed without using a straight slit. By using , the degree of freedom becomes even greater. Further, in d, such a shape can be obtained by placing one convex pattern 17d in the second stage.
