) and transmission line (8), and check the optical axis deviation of the laser oscillator (1). This method uses a laser oscillator (
An optical axis adjuster (6) is placed on a height-adjustable pedestal (5) in front of 1). This optical axis adjuster (6) is equipped with a light source that oscillates a laser of visible wavelength with lower output than CO2 laser light, for example, a He-No laser. Therefore, the He--He laser beam from the optical axis adjuster (6) is replaced with a He--Ne laser as in the oscillation embodiment. Therefore, the optical axis of the oscillator (1) is adjusted by a conventionally known method, and the processing head (2) and the transmission line (
8) is attached to the oscillator (1) to detect the deviation of the laser optical path of the transmission system as shown in FIG. 8(b). In this case, the optical axis adjuster (6) is set at the connection part (7) between the oscillation R (1) and the transmission line (8), and the pend mirror (not shown) is installed inside the connection part (7). Through the transmission line (8), the processing head (2) guides the VCHe-Ne laser. To detect the deviation at this time, adjust the optical axis as described above.
□ Laser light is emitted to the transmission line (8), processing head (2)
This is done by checking the deviation between the nine points marked by the c and o2 laser beams and the irradiation position of the He-Ne laser beam. Therefore, the pendomirr-HHe-No laser light and the CO2 laser light installed in the connecting portion (γ) are alternately switched and introduced into the transmission line (8). If there is a positional shift between these two, the transmission line (8
) can be corrected by adjusting the degree of inclination of the pend mirror (4) attached to the mirror.

業が煩雑になるという問題点を有していた。Adjustment of the optical axis, etc. in conventional laser processing machines is performed using an oscillator (
1) and the transmission line (8) etc., and after adjusting the optical axis of the oscillator (1), attach the transmission line (8) etc. to the oscillator (1) and connect the C02 laser beam and the optical axis adjuster (6). Next, it is necessary to correct the optical path of the C02 laser beam in relation to the He-No laser beam. In other words, in the conventional adjustment, the above-mentioned disassembly and assembling work is required each time, and the VC also requires work space during disassembly. Therefore, there was a problem in that maintenance and inspection work became complicated.

The deviation is detected from the relationship between the emitted light guided by the oscillator and the adjusted emitted light from the oscillator, and the optical path can be adjusted by adjusting the inclination angle of the pendor mirror or the like of the transmission path.
