    • The invention includes an irradiation nozzle which radiates a line scanning beam, an irradiation position sensor which detects an irradiation position of the line scanning beam, an arithmetic processing circuit unit which measures the stationary time of the line scanning beam at the irradiation position detected by the irradiation position sensor, and an irradiation control unit which performs scanning control of the line scanning beam by utilizing the irradiation position measured by the irradiation position sensor and the stationary time detected by the arithmetic processing circuit unit. According to this line scanning apparatus, scanning control of the line scanning beam is performed by utilizing the irradiation position of the beam and the stationary time corresponding to the irradiation position, so that irradiation of the beam to an erroneous position or excessive irradiation of the line scanning beam can be more reliably prevented, and thereby the reliability of the line scanning apparatus can be improved.
    • 本发明包括:辐射线扫描光束的照射喷嘴,检测线扫描光束的照射位置的照射位置传感器;运算处理电路单元,测量由扫描光束检测的照射位置处的线扫描光束的静止时间; 照射位置传感器和照射控制单元,其通过利用由照射位置传感器测量的照射位置和由运算处理电路单元检测到的静止时间来执行行扫描光束的扫描控制。 根据该行扫描装置,通过利用光束的照射位置和对应于照射位置的静止时间来进行线扫描光束的扫描控制,使得将光束照射到错误位置或线的过度照射 可以更可靠地防止扫描光束,从而可以提高线扫描装置的可靠性。
