ABSTRACT:
An uninterruptive power supply is connected to an engraving apparatus. When power failure occurs, with supply of electric power from a back-up power source which is disposed within the uninterruptive power supply, a blank line detection part detects a closest blank line yet to be engraved, based on detection of the power failure by a power failure detection part. An engraving machine controller then ensures continued engraving up to the closest blank line and stops engraving. Following this, engraving is resumed after power supply is recovered.
