    • A magnification changing device for use in a copying machine, capable of effecting a scale-up and-down magnification of a manuscript. The device has a first reflecting mirror system adapted to be moved at a constant speed and arranged to receive the optical image from an object, and a second reflecting mirror system adapted to receive the light reflected by the first reflecting mirror system and to move in the same direction as the first reflecting mirror system at a speed which is a half that of the movement of the first reflecting mirror system. The device also has a fixed magnifier lens upon which the light reflected by the second reflecting mirror system impinges, a movable third reflecting mirror system adapted to receive the light coming through the lens, and a magnification changing mechanism for moving the reflecting mirror systems in synchronism with each other such that a relationship corresponding to varying magnification degree is maintained between the distance between the first and second reflecting mirror systems and the distance between the lens and the third reflecting mirror system. According to this arrangement, any desired magnification degree is set by the magnification changing mechanism while focussing the light from the third reflecting mirror system.
    • 一种用于复印机的放大倍数改变装置,能够进行原稿的放大缩小倍率。 该装置具有适于以恒定速度移动并被布置成从物体接收光学图像的第一反射镜系统,以及适于接收由第一反射镜系统反射的光并在其中移动的第二反射镜系统 与第一反射镜系统相同的方向,其速度是第一反射镜系统的运动的一半。 该装置还具有固定的放大镜透镜,由第二反射镜系统反射的光入射到该固定放大镜透镜上,适于接收透过透镜的光的可动第三反射镜系统和用于同步地移动反射镜系统的倍率改变机构 使得在第一和第二反射镜系统之间的距离与透镜和第三反射镜系统之间的距离之间保持对应于变化的放大度的对应关系。 根据这种布置,通过倍率改变机构设定任何期望的放大度,同时聚焦来自第三反射镜系统的光。
