The light reflector includes a plurality of reflecting portions and reflects, at least twice, the light radiated from the light projector to guide the light to the intended irradiated point. The reflecting portions each include a plurality of reflecting surfaces. A length of an optical path from the light projector to the irradiated point is substantially constant for all of irradiated points on the scanning line, and a scanning speed, on the scanning line, of the light radiated from the light projector is substantially constant.

摘要： A laser processing device having a simple structure and a means for accurately detecting expansion and misalignment of a laser beam. A sensor, which receives the laser beam after transmitting through a half mirror, is arranged on a back surface of the half mirror opposed to a front surface which reflects the laser beam. The sensor is positioned via a heat insulating material between the back surface of the half mirror and a shield plate for shielding or absorbing the laser beam after transmitting through the half mirror, so that the sensor is thermally-independent from the other components. The sensor is positioned so that the sensor does not receive the laser beam after transmitting through the half mirror in the normal state, and so that the sensor directly receives the laser beam after transmitting through the half mirror when the laser beam is expanded or misaligned.
