Document Type and Number:
Japanese Patent JP2781898
Kind Code:
B2
Abstract:
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.
