    摘要： A variable magnification electrostatic copying apparatus comprising a transparent plate (4) on which to place a document to be copied, an optical system (62, 66, 72, 70, 60, 78) for projecting the image of the document onto an electrostatographic photosensitive member (10) at any desired projecting ratio selected from a plurality of projecting ratios in an exposure zone (26) located along the moving path of the photosensitive member, and a driving means for moving at least a part of the optical system and the transparent plate relative to each other. The optical system includes at least one position-variable optical element assembly (74) adapted to be held at any of a plurality of positions corresponding to the aforesaid plurality of projecting ratios. The variable magnification electrostatic copying apparatus includes a unique improved means (182) for varying the projecting ratio of the optical system by moving the position-variable optical element assembly.

    摘要： @ A unit-type copying machine comprising an upper unit having an optical system for exposing a document to light by scanning, and a lower unit provided independently of the upper unit and having a photoconductive drum to be exposed to an image of the document projected thereon from the optical system. The upper and lower units are provided with connecting portions for detachably connecting the two units together and positioning portions for positioning the optical path of projection of the document image from the optical system in coincidence with an exposure station for the drum. The upper or lower unit is usable with selected one of different types of lower units or of different types of upper units in a suitable combination.

    摘要： A cleaning device in an electrostatic copying apparatus for removing residual toner particles from the surface of a photosensitive member adapted to move through an endless conveying passage, which comprises a blade holding mechanism (52, 54) mounted pivotally around an axis (48) extending substantially parallel to the surface of the photosensitive member (30) and substantially perpendicular to the moving direction of the photosensitive member and a cleaning blade (56) mounted on the blade holding mechanism. This cleaning device (56) further includes a first spring means (70) for elastically biasing the blade holding mechanism to a non-operating position at which the cleaning blade (56) moves away from the surface of the photosensitive member (30) and a specially improved operating mechanism for selectively positioning the blade holding mechanism against the elastic biasing action of the first spring means (70) at an operating position at which the cleaning blade (56) is pressed on the surface of the photosensitive member (30).
