Abstract

PURPOSE: To engrave a stamp with extreme precision and high efficiency, by specifying the output of the gaseous CO2 laser and the parallel distance of the scanning lines of the machining point of the laser beam.
CONSTITUTION: The lens that converges a laser beam 20 is focused on a surface 6a of the stamp. The parallel distance of the scanning line l of the machining point P' of the laser beam, that is, the feeds of the both turn tables 6, 8 to a vertical direction are adjusted to 0.015W0.05mm, and the output of the applied gaseous CO2 laser 9 is adjusted to 30WW120W. The reflected beam of the detecting ray projected from a projecter 16 to the original drawing 7 is received by a recepter 17. The reflected beam is intense on the white part of the basic material surface of the original drawing 7 and it is feeble on the black written part of the drawing. This intensity is detected by the recepter 17, and by these detecting signals the oscillation of the laser beam 20 from the gaseous CO2 laser 9 is intermitted via the electric control circuit 19, and thus the reversed letters are engraved upon the surface of the stamp.
