PROBLEM TO BE SOLVED: To secure safety of an operator and also to improve workability by doing close at hand a checking operation in which the focal position of a laser beam is made coincident with the machining position of a work. SOLUTION: The main body 3 of a handy torch is provided with a sensor 9 for checking the focal position of a laser beam to be coincident with the machining position of a work W to be machined, and also provided with a monitor 11 for monitoring an image photographed by the checking sensor 9. A movable reflection mirror which performs switching between the emission of a laser beam and the confirmation by the checking sensor 9 is movably disposed, and in addition, a balancer 17 is attached to the main body 3 of the handy torch. |
