PROBLEM TO BE SOLVED: To make drilling of high processing positional accuracy possible by appropriately determining and applying correction information even when an inter-shaft distance does not come to integral multiplication of a block width regulated by a standard mark provided on an object to be processed in laser processing of multi-shaft type for performing processing of a plurality of portions set apart from each other by a prescribed distance all at once.SOLUTION: A laser processing device which performs processing by dividing a processing range of an object to be processed by a plurality of laser irradiation systems set apart from each other by a prescribed distance includes: a control part which causes each of standard mark reading parts, provided in every laser irradiation system, to read a standard mark such that regions partially overlap with each other over a region broader than the processing range of the laser irradiation systems corresponding to each of the standard mark reading parts and performs a control so as to process the object to be processed by using correction information obtained by the corresponding standard mark reading part in each of the laser irradiation system.SELECTED DRAWING: Figure 1 |
