PROBLEM TO BE SOLVED: To carry out simply and accurately registration of a laser beam wherein a cutting position of a material to be cut and a cutting position of a cutting edge tool are indicated. SOLUTION: For this mechanism, a laser oscillator 30 is housed in a hollow part 33 of a support member 32, a ball 34 is fitted between the support member 32 and a laser oscillator 30, a first stopper 35 and a second stopper are fitted by threading to the hollow part, and a laser beam L is conformed to a reference position X by swinging the laser oscillator 30 in a left and right direction by the first stopper 1. Further, the laser beam L is conformed to another reference position by swinging up and down the laser oscillator 30 by the second stopper.
