摘要：
An engraving method is switched from line engraving to dot engraving (or vice versa) at a boundary line at every horizontal scanning by generating and controlling switching signals by means of an engraving discrimination plate. An engraving is performed while a sweeping operation is being performed in a direction (X direction) substantially parallel to a long side of a portion of a card requiring engraving. Since the number of horizontal sweepings are reduced considerably in comparison with the conventional method, the time required for engraving can be shortened. The engraving table can be produced more light in weight : as a result, a higher speed of the movement of the engraving table can be achieved, thus making it possible to further shorten the time required for engraving.
摘要（中）：
雕刻方法通过雕刻识别板通过产生和控制开关信号在每个水平扫描的边界线上从线雕刻切换到点雕刻（反之亦然）。 当在基本平行于需要雕刻的卡片的一部分的长边的方向（X方向）上执行清扫操作时执行雕刻。 由于与传统方法相比，水平扫描的数量显着减少，雕刻所需的时间可以缩短。 雕刻台的重量可以更轻，因此可以实现雕刻台移动的更高速度，从而可以进一步缩短雕刻所需的时间。
