To provide a printed circuit board working machine with which even in the case of being an uneven stopping time of the printed circuit board working machine, the working can surely be succeeded and also, work quality can be maintained.
This machine is provided with a period setting means 31 for setting a plurality of periods, a time measuring means 30 and a power measuring instrument 16 for measuring the power of laser beam 5, and the time measuring value of the time measuring means 30 is constituted so as to reset at each output of the laser beam 5 in a laser beam apparatus 2. In the case that the time measured value when the laser beam 5 is outputted is shorter than a first period, a work 12 is irradiated with the laser beam 5, and in the other case, the power of the laser beam 5 is measured. In the case that the measured power value is in the permissible range, the work 12 is irradiated with the laser beam 5, and in the other case, the power is again measured after outputting the laser beam 5 according with a preset program in a second period, and in the case that the measured power value is in the permissible range, the work 12 is irradiated with the laser beam 5.
