    • Apparatus for scanning an original in a copying machine herein disclosed is of the type in which first and second mirrors are moved in the same direction at the velocity rate of 1:1/2. The apparatus comprises first and second carriages for supporting and carrying the first and second mirrors respectively, a guide rail for supporting the carriages movably in the direction of their movement and a particular arrangement of pulleys to move the mirrors. The arrangement comprises first and second movable pulleys provided on the second carriage and spaced from one another and first and second stationary pulleys. The first stationary pulley is positioned on the side of the second movable pulley relative to the first movable one whereas the second stationary pulley is positioned on the side of the first movable pulley relative to the second one. A wire extends over passing around these pulleys, with its one end being fastened to a stationary part of the apparatus after being passed around the first stationary pulley and then around the first movable pulley. The other end part turned back around the second stationary pulley extends to the second movable pulley where it turns back around the pulley and then its end is finally fastened to a stationary part of the apparatus. At the segment of the pulley wire extending between the first stationary pulley and the first movable pulley, the first carriage is fixedly connected with the wire so as to cause the first and second mirrors to move with the movement of the wire.
    • 本文公开的复印机中用于扫描原件的装置是其中第一和第二反射镜以1:1/2的速度向同一方向移动的类型。 该装置包括用于分别支撑和承载第一和第二反射镜的第一和第二托架,用于沿其运动方向可移动地支撑托架的导轨和用于移动反射镜的特定布置的滑轮。 该装置包括设置在第二滑架上的第一和第二可移动滑轮,并且彼此间隔开以及第一和第二静止滑轮。 第一固定滑轮相对于第一可移动滑轮位于第二可动滑轮的一侧,而第二固定滑轮相对于第二固定滑轮位于第一可移动滑轮的侧面。 线绕着这些滑轮延伸穿过,其一端在穿过第一固定滑轮之后并且然后围绕第一可动滑轮紧固到设备的固定部分。 围绕第二固定滑轮转动的另一端部分延伸到第二可动滑轮,其中它绕着滑轮转回,然后其端部最终紧固到装置的静止部分。 在第一固定滑轮和第一可动滑轮之间延伸的滑轮线的段处,第一滑架与导线固定连接,以使第一和第二反射镜随着导线的运动而移动。
