    • PURPOSE: An equipment for blocking the beam passing line of a laser scanning unit is provided, to allow the blocked state to be maintained irrespective of the turning on or off of an equipment, thereby preventing the invasion of impurities or the outflow of a laser beam. CONSTITUTION: The equipment(100) comprises a sliding window member(130) which has a beam passing window corresponding to a beam passing line(5) and can slide between the position blocking the beam passing line and the position opening the beam passing line; a shutter(110) which can slide the blocking position and the opening position horizontally to the sliding direction of the sliding window member between the sliding window member and the beam passing line; a position fixing means(180) which elastically compresses the shutter on the blocking position; and a shutter moving means(150) which is located between the sliding window member and the shutter and moves the shutter from the position where the beam passing window corresponds to the beam passing line to the opening position.
    • 目的:提供一种用于阻挡激光扫描单元的光束通过线的设备,以便能够保持阻挡状态,而与设备的接通或关闭无关,从而防止杂质的侵入或激光束的流出 。 构成:设备(100)包括滑动窗构件(130),其具有与梁通过线(5)相对应的梁通过窗口,并且可以在阻挡梁通过线的位置和打开梁通过线的位置之间滑动; 能够使滑动窗构件和梁通过线之间的滑动窗构件的滑动方向水平地滑动阻挡位置和打开位置的挡板(110) 位置固定装置,其在所述阻挡位置弹性地压缩所述活门; 以及位于滑动窗构件和快门之间的快门移动装置(150),并且将快门从射束通过窗对应于射束通过线的位置移动到打开位置。
