摘要： A sheet member feed apparatus for use in an electrophotographic copying machine includes a frame with a pair of spaced opposed walls, each wall having therein an elongated hole defined by longitudinally extending inner wall side faces. First and second feed rollers are mounted on first and second shafts, respectively, with each shaft having bearings at opposite ends thereof. The bearings of one shaft are mounted at fixed positions in the opposed frame walls, and the bearings of the other shaft are mounted in the elongated holes with clearance between outer side faces of the bearings and the confronting inner wall side faces, such that the other roller is movable toward and away from the one roller. A spring extends around a portion of each of the bearings of the other roller and biases the bearings in the elongated holes in a direction to urge the other roller toward the one roller. As a result, rotation of the other roller tends to cause the outer side faces of the bearings thereof to repeatedly impact against confronting inner wall side faces of the respective elongated holes. Biasing structure prevents such repeated impacting by biasing the bearings of the other roller such that the resultant force of forces acting on such bearings extend from the center of the shaft of such roller toward one longitudinal inner wall side face of the respective elongated holes at a particular angle of inclination.

摘要： An optical device in a variable magnification electrostatic copying apparatus includes a first reflecting mirror assembly mounted for reciprocal movement, a second reflecting mirror assembly mounted for reciprocal movement substantially parallel to the reciprocating direction of the first reflecting mirror assembly, and a speed-reduction interlocking mechanism for moving the second reflecting mirror assembly at a speed equal to one-half of the moving speed of the first reflecting mirror assembly, upon movement of the first reflecting mirror assembly. The optical device further includes a magnification setting mechanism for changing the relative position of the second reflecting mirror assembly with respect to the first reflecting mirror assembly according to a desired copying magnification. The magnification setting mechanism comprises a setting cam having a plurality of acting portions corresponding to a plurality of magnification values and a setting member adapted to be held by the setting cam at any one of a plurality of setting positions corresponding to the plurality of magnification values. The changing of the position of the setting member causes a change in the relative position of the second reflecting mirror assembly with respect to the first reflecting mirror assembly.

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, includes a blade holding mechanism mounted pivotally around an axis extending substantially parallel to the surface of the photosensitive member and substantially perpendicular to the moving direction of the photosensitive member, and a cleaning blade mounted on the blade holding mechanism. The cleaning device further includes a first spring elastically biasing the blade holding mechanism to a non-operating position in which the cleaning blade is away from the surface of the photosensitive member and an operating mechanism selectively positioning the blade holding mechanism against the elastic biasing action of the first spring to an operating position in which the cleaning blade is pressed against the surface of the photosensitive member. The operating mechanism includes a clutch with an input drivingly connected to the photosensitive member drive system, a cam, a cam follower, and a power transmission arrangement for transmitting power from the cam to position the blade holding mechanism so that the cleaning blade is pressed against the surface of the photosensitive member. The power transmission arrangement includes a first power transmission member, having an input terminal on which the cam acts, and a second power transmission member, having an output terminal acting on the blade holding mechanism.

摘要： The housing of a delivery unit is engaged with a predetermined part of the body of an image forming apparatus, the housing being pivotable upwardly from the body. An endless belt is wound on a pair of pulleys. One of the pulleys is mounted on a first shaft which is secured to the housing which is latched in position on the body while the other pulley is mounted on a second shaft that is movable with respect to the housing. The second shaft is attached to the body, and the endless belit is stretched to restrain the housing from being unlatched and pivoted upwardly from the body. The delivery unit is attached without use of screws. Accordingly, the delivery unit may be readily placed in its operating position on the body with no possibility of the photoreceptor being damaged. In an image forming apparatus having electric component elements disposed under the delivery unit, the maintenance of the element is facilitated.

摘要： A method for cleaning a photoreceptor of an image forming apparatus includes actuating a cleaning means of a cleaning system and rotating the photoreceptor before a usual image forming operation, after a predetermined time, charging a particular area of the photosensitive drum, transferring residual toner adhering to a sealing member of a developing unit to the charged area, carrying the transferred residual toner with rotation of the photoreceptor to the cleaning means of the cleaning device, and removing the residual toner by the cleaning means. Accordingly, the present invention eliminates the possibility of mixing of the color of a previously used toner into a toner image after replacement of a developing unit by another unit containing a different color of toner.

摘要： A compact sheet processing apparatus mountable on the side of a copying machine body processes sheets discharged therefrom. The apparatus includes a sheet supplier for supplying sheets received from the copying machine body; a sheet discharger; a first transport route connecting the sheet supplier and discharger, and a sheet-stamping mechanism disposed opposite the sheet-bearing surface of the first transport route. Further included is a second transport route, diverging from and extending below the first transport route, which feeds sheets to a punching mechanism disposed therein; a transport drive providing controlled transport of sheets in each transport route; and a process timing control unit. The sheets are transported along both the first and second transport routes wherein the stamping and punching operations are both to be carried out, and then discharged through the discharger. The timing of the processes is controlled according to set conditions. Transport within the reduced-dimension apparatus is such that wherein holes are punched into a sheet in the punching mechanism, drive in a latter-stage unit such as a sorter mounted at the discharger need only be halted, a reversing capability or the like thereof thus being unnecessary.
