つた。 The present inventor previously proposed a stamp engraving device using an XY table (Japanese Patent Application Laid-Open No. 55-69458). As shown in FIG. 11, this device engraves a stamp surface 5 by reciprocating a laser beam 30 with an intensity corresponding to the shape to be engraved in the X-axis direction and advancing it in the Y-axis direction by one pitch per scan. is engraved using parallel scanning lines with different directions, the scanning range can be limited according to the number of stamps to be engraved, the time required for engraving can be kept to the minimum necessary, and the stamp surface can be engraved at the same speed. It is characterized by the fact that the engraving depth is constant. However, when the scanning speed is increased, at a certain limit value, the response of the means for reading the figure to be engraved and the laser processing device controlled by the means no longer follows the scanning speed, and the actual range to be engraved becomes smaller than the actual range to be engraved. As a result of the receding of the area to be processed, as shown in the enlarged diagram,
There was a problem in that the boundary portion 37 of the machined surface 36 shifted left and right with each scan, making it impossible to increase the processing speed very much.

ならないなど不都合が多い。 To solve the above problem, we proposed a device that uses a rotary table in place of the XY table and scans the stamp surface in a spiral pattern as shown in Figure 12 by moving the table at low speed in the Y-axis direction while rotating the table ( (Japanese Patent Application Laid-open No. 105598/1983). When scanning with such a device, the scanning direction of the scanning line is the same over the entire stamp surface, and as a result, the unevenness of the boundary 37 of the processed surface 36 disappears, and the processed surface 36 only shifts overall as the scanning speed increases. Therefore, such a shift can be easily corrected mechanically, and the scanning speed can be increased. On the other hand, the scanning range cannot be changed according to the number of stamps to be engraved, and the processing time is the same whether one stamp is engraved or a plurality of stamps are engraved. Furthermore, if the rotational speed of the table is constant, the scanning speed will increase as scanning progresses from the outer circumference of the table to the inner circumference of the table. Therefore, if you try to keep the engraving depth constant, the rotational speed of the table will increase as the scanning position moves. Alternatively, there are many inconveniences such as the need to continuously change the irradiation intensity of the laser beam.

る印判彫刻方法を提供することを目的とする。 The present invention was developed in view of the above-mentioned disadvantages, and by performing linear scanning using an XY table, the scanning direction is changed to the machined surface while maintaining the constancy of the scanning speed and the variability of the scanning range. It is an object of the present invention to provide a stamp engraving method that can prevent unevenness at the processing surface boundary caused by the responsiveness of the processing device by keeping the pressure constant over the entire area.

て走査されるのである。 The present invention is characterized by the moving path of the XY table 3, that is, the scanning path of the stamp surface 5 by the laser beam. Hereinafter, as shown in FIG. 5, an example will be described in which two sets of stamp groups 1a and 1b of ten stamps, five stamps each in the front and rear rows of the stamp mounting section 2, are attached for engraving. The length in the X-axis direction
W 1 , the distance between both stamp groups 1a and 1b is D 1 , the scanning pitch is h 1 , and the left rear edge of the side stamp group 1a is the scanning start point 35 , then W in the X-axis direction from the starting point 35 After scanning the stamp group 1a on the front row side, move forward by D 1 in the Y-axis direction, the processing point by the laser beam will be at the right rear edge of the stamp group 1b on the back row side, so this time move in the negative direction of the X-axis. By shifting to W1 , the stamp group 1b on the back row side is scanned to the left. When this scanning is completed, the processing point has moved to the left rear edge of the rear stamp group 1b, so it is further moved in the negative direction of the Y axis.
By advancing D 1 + h 1 , it reaches a point 1 pitch in the Y-axis negative direction from the previous scanning starting point 35,
One scan cycle is completed. By continuing this scanning cycle until the processing point reaches the front edge of the stamp groups 1a and 1b, the stamp group 1a on the front row side
is scanned in parallel to the right at pitch h1 , and on the contrary, the seal face 5 of the stamp group 1b in the back row is scanned to the left over its entire surface.

同様な動作が期待できる。 In this embodiment, the position of the trailing edge of the row-side stamp group 1a is regulated by the holding surface 12, and is constant regardless of the stamp size, so it is suitable as the scanning starting point 35, but is not limited thereto, as shown in FIG. The front edge of the front stamp group 1a may be set as the scanning starting point 35, as shown in FIG. Alternatively, as shown in FIG. 7, a similar operation can be expected if the laser beam is scanned in a spiral manner every scanning cycle.

り同一方向に走査される。 Furthermore, the stamp group is not limited to two rows,
The present invention can also be practiced in the case of a single row as shown in FIG. 8 or an even number of rows as shown in FIG. In the case of one row, each time one scan is completed, the outer periphery of the stamp group 1a is moved by the shortest distance, and the process returns to a position 1 bit further in the Y-axis direction from the previous scan start point. When there are four rows of stamp groups, two rows are treated as one set, and scanning is performed in substantially the same procedure as in the case of two rows, so that each stamp surface is scanned in the same direction over the entire surface.

It is possible to space the stamps 1c apart from each other and arrange the stamps 1c also in the section transitioning from one stamp group 1a to the other stamp group 1b. In this case, it is necessary to shift the scanning line one bit at a time in the Y-axis direction and also to shift the scanning line one bit at a time in the X-axis direction.

判を彫刻する場合も同様である。 In the above embodiment, the scanning range is set numerically using the keyboard 34 according to the number or diameter of stamps, but it is also possible to arrange a micro switch for stamp detection on the holding surface 12 of the stamp mounting section 2. At the same time as the stamp is set, the range to which the stamp is attached can be detected, and the range to be scanned by the laser beam can be automatically set. The same applies when engraving a square seal.

ことを兼ね備えるという優れた効果を有する。 As described above, the present invention uses an XY table to perform linear scanning, and the scanning direction is set in the same direction over the entire area of the stamp surface 5. Therefore, the feature of linear scanning, that is, the scanning range can be easily changed. While maintaining the ability to change the scanning speed and keeping the scanning speed the same over the entire area, the machining boundary line does not become uneven even if the scanning speed is increased, which is a feature of spiral scanning, increasing the machining speed. It has the excellent effect of being able to achieve both.
