Abstract: A laser processing head is provided with: an optical component for splitting a laser light into a laser light and a laser light; a scanning unit for scanning the laser light; a light reception unit for detecting the intensity of the laser light; a second shutter that shifts between a closed position in which the laser light is blocked and an open position in which the laser light is transmitted; and a focal distance adjustment unit for adjusting the focal distance of the laser light. The second shutter is arranged between the optical component and the focal distance adjustment unit.

Abstract: This laser processing device comprises a processing pattern input unit, a two-dimensional display unit, a three-dimensional position display data generation unit for generating three-dimensional position display data compatible with three-dimensional display, a profile information input unit, a three-dimensional display unit, a processing-condition-setting unit for displaying the position of a processing pattern on a surface being processed by using the three-dimensional position display data and setting a processing condition as position information, and a three-dimensional laser processing control data generation unit for generating three-dimensional laser processing control data in accordance with the processing condition. The processing condition is edited after display is carried out such that the processing pattern is replaced with three-dimensional position display data having a smaller data volume by a setting terminal; therefore, it is possible to smoothly edit the processing condition.

Abstract: A laser processing device comprises: a first shutter that shifts between a closed-state position for blocking a laser beam and an open-state position for allowing the laser beam to pass; a second shutter that shifts between a closed-state position for blocking laser beams and an open-state position for allowing the laser beams to pass; a first closed-state sensor that detects that the first shutter is disposed at the closed-state position; a first open-state sensor that detects that the first shutter is disposed at the open-state position; a second closed-state sensor that detects that the second shutter is disposed at the closed-state position; and a second open-state sensor that detects that the second shutter is disposed at the open-state position.

Abstract: An electromagnetic relay includes a base, an electromagnet block fixed to the base, an armature which reciprocates when the electromagnet block is switched between an excitation state and a non-excitation state, and a card which slides in association with the movement of the armature. The base includes a rail portion which guides the card upon sliding, and the card includes a slide portion which slides along the rail portion. The rail portion includes a stopper portion which prevents disengagement of the slide portion from the rail portion.
