Abstract: In a copying machine a copy-receiving device is provided which includes a table with a plate inclined to a horizontal at a predetermined angle and supporting thereon sets of copies or sheets to be stapled together by a stapling device which is insertable into the copy-receiving device and arranged at the lower end of the inclined plate. The stapling device is actuated by a drive motor, a crank drive with a pulling bar having an end portion with a compression spring thereon, and an actuating arm pivotally connected to the end portion of the pulling bar. The spring compensates for various thickness is of the stacks of sheets being stapled and provides for displacement-free stapling of the sheets.

Abstract: An apparatus for squaring, stapling, and stacking copies is used in combination with a copier that produces a succession of sheet copies and has a housing adapted to be positioned adjacent the copier, an upper support plate in the housing positioned to receive the copies from the copier and having a downstream end remote from the copier, and a stop flap at the downstream end and pivotal between a position blocking copies from sliding down off the downstream end and a freeing position permitting copies to slide down off the downstream end. A downwardly inclined lower support plate in the housing below the downstream end of the upper plate is positioned to receive copies sliding in the freeing position of the stop flap off the downstream end of the upper plate. A stapler is fixed in the housing adjacent the upper plate upstream of the downstream end thereof and an actuator is connected to the stapler for closing same on a stack of copies on the upper plate for stapling same together.

Abstract: The electromagnetic disk-free clutch includes a cylindrical rotor supported on one rotary part and defining at one end face a frictional disk and at the other end face an annular groove which accommodates a tubular stator with an electromagnetic coil. The frictional ring of the rotor faces a corresponding frictional ring of a spring-biased armature which is supported for joint rotation and for an axial displacement on the other rotary part. The stator part adjoining the open end of the annular gap is radially extended to form a covering flange having a cross section substantially equal to the cross section of the axially directed parts of the stator and the rotor. The face of the rotor forming the frictional ring is provided with uniformly distributed openings and the axial dimension of the annular groove in the rotor exceeds that of the stator.

Abstract: The cleaning arrangement of an electrophotographic copying machine scrapes off the machine's copying drum residual toner clinging to the surface of the copying drum subsequent to image transfer, and the residual toner is conveyed generally horizontally into a toner-collection compartment. The toner-collection compartment accommodates a generally rigid but collapsible fold-up cardboard toner-collection container which is thrown away after one use. The throw-away toner-collection container, when in collapsed condition, is flat so that a sizable number of such throw-away containers can be kept on hand without requiring an inconvenient amount of storage space.

Abstract: A copying apparatus is disclosed wherein an original is scanned by a light beam which is then transmitted along a path to the photosensitive surface of an imaging drum. A pair of baffles is arranged symmetrically relative to the aforementioned path and a motion-transmitting arrangement is provided, which is controlled from outside the copying apparatus and which serves to synchronously pivot the baffles into and out of the path to thereby control the amount of light which reaches the photosensitive surface of the drum.
