Filed: 2001-02-15
Abstract: PROBLEM TO BE SOLVED: To provide a device for marking with laser beam which correctly detects an abnormality of the output of the laser beam source while increase in its production cost is suppressed. SOLUTION: When the laser beam source 10 is deteriorated due to, for example, a long term of use of the device 1 for marking with laser beam, the output of the laser beam source 10 is decreased. Thus, the light quantity of the laser beam which is received by a galvano-mirror 20V also decreases, the surface temperature of the galvano-mirror 20V drops in comparison with a normal condition. Accordingly, an electric signal level outputted from a heat-radiation type temperature sensor 40 also becomes lower than a reference value, and a signal of abnormal output is given to a controller 30 by an abnormality discrimination means 50.
