Abstract

PURPOSE: To provide a safety device against the laser beam between the laser oscillator and the work in a laser processing device adapted to process the work by an application of focussed laser beam.
CONSTITUTION: A protective cover 8 as means for preventing the out-of-control of laser beam is provided with a heat-sensitive device 9 for detecting the temperature. The arrangement is such that the output of the laser oscillator is interrupted as the heat-sensitive device 9 detects an extraordinary temperature rise of the cover 8. The device 9 is constituted by an corganic heat-sensitive body 9 unitarily wound around the protective cover 8 consisting of a metal or cloth at a pictch smaller than the diameter of the laser beam. The output of the laser oscillator is cut when the temperature is, for example, between the room temperature and 70°C, due to the reduction of impedance of the heat-sensitive body attributable to the temperature rise.
