Abstract

PURPOSE:To print various kinds of characters, symbols, etc. at a high speed on a large quantity of parts, etc. by irradiating a laser beam to a member to be subjected to printing, through a sheet for a mask punched with characters, symbols, etc. CONSTITUTION:A sheet 3 for a mask is disposed substantially apart from the surface of a part or product 5 to be subjected to printing. A laser beam 2 is irradiated through said sheet 3 to said part or product, whereby the beam 2 is irradiated on the part or product 5 in the reduced shape of the character or symbol 4 formed by punching on the sheet 3. The laser beam is so adjusted in this stage that the intensity per area of the beam 2 in the punched character or symbol 4 is substantially small to the extent of avoiding melting the material of the sheet 3 and that the intensity per area of the beam 2 on the part or product 5 to be subjected to printing is substantially large to the extent of melting the material of the product 5.

Using a mirror such as a concave mirror (not shown), the irradiation is focused on the inside of the part or product 5 to be printed from the surface. In addition, by arranging a masking sheet 3 light-separated from the surface of the part or product 5 to be printed, and irradiating the laser beam 2 through this masking sheet 3,
The laser beam 2 is irradiated onto the part or product 5 with the perforated characters or symbols 4 formed on the mask sheet 3 having a reduced shape.

When printing on the item or product 5, use the mask sheet 3.
Because it does not require high heat resistance, it can be easily obtained at low cost, and since the shape of the character or symbol 4 is reduced and irradiated onto the part or product 5, the shape of the character or symbol 4 is made relatively large. The shapes of the characters and symbols 4 can also be created freely. Also, regarding printing control, the part or product 5 to be printed may be moved in the direction shown by the arrow in Fig. 2, and when it comes to a fixed position, the second laser beam may be irradiated; Even when changing the desired character or symbol 4, all you have to do is feed the mask sheet 3 in the direction shown by the arrow in Figure 2 until the desired character or symbol 4 is at the specified position. Control can be performed very easily.
