A photographic copying machine has a copying unit which must receive a web of unexposed photosensitive web material well above the floor level. The web material is confined in cassettes which must be lifted before they reach a level in which the web material which is confined therein can be drawn into the copying unit. In order to facilitate manual manipulation of a relatively heavy and bulky cassette, the latter is provided with handless and with one part of a separable coupling which constitutes a hinge and enables the person in charge to pivot the cassette to an upright position subsequent to manual lifting approximately to the chest level. If necessary, the pivoted cassette is thereupon pushed into a chamber of the copying unit. A cassette for reception and storage of freshly exposed photosensitive web material can be manipulated in the same way.

An apparatus for aligning and squaring a stack of sheets has a support plate having a generally horizontal and flat support surface adapted to support the stack of sheets, a guide projecting upward from the support surface and having an abutment face directed in a predetermined direction generally parallel thereto, and a generally horizontal rod vertically spaced from the surface and stack and extending in the direction. A pusher element carried on the rod is slidable thereon in the direction, friction alone linking the element and rod together in the direction. This pusher element is engageable with a sheet on the surface. A stop facing opposite to the direction is also engageable with the element. A drive reciprocates the rod in the direction through a predetermined stroke toward and away from the guide. Thus on displacement toward the guide the element engages and pushes a sheet opposite the direction until the sheet engages thereagainst, at which time the element slides on the rod. On opposite displacement the element engages the stop and is displaced relative to the rod in the direction to its starting position on the rod.

Apparatus for aligning sheets in a stack

An arrangement for transporting a sheet-like data carrier with reversing its direction of movement and at the same time maintaining its original orientation has first and second transporting paths and a reversing path, a turnable lever located between the first and second transporting paths and having a length and a mounting point selected so that one of the supporting rollers arranged on the lever can be brought to abutment against one transporting roller of the second transporting path and simultaneously the other supporting roller of the lever comes to a position below the first transporting path, a sensing element arranged at the reversing path and operative for sensing a front edge of the data carrier, and a controlling element operative to control the movement of transporting rollers of the reversing path and the turnable lever in response to the sensing by the sensing means, so that reversing of transporting direction of the transporting rollers of the reversing path and turning of the turnable lever to a position in which the other supporting roller comes to abutment against one transporting roller of the second transporting path takes place before the front edge of the data carrier has passed the supporting roller located below the first transporting path.

Transporting arrangement for sheet like data carriers

A developer device for electrostatic copiers includes a housing in which toner is circulated. The circulating toner is dropped in free fall at a predetermined location. Underneath that location are two side-by-side lengthwise extending channels into which the falling toner is substantially uniformly distributed. Guide baffles in one channel direct the incoming toner along the channel in one direction, and guide baffles in the other channel direct toner in the opposite direction.

Developing device for copier

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. The bottom of the container projects forwards beyond the top, in the direction opposite to the generally horizontal direction of toner conveyance into the collection compartment, and is furthermore provided with an upright standing rim, the forwardly projecting bottom ledge and such rim preventing inadvertent spilling of toner from the collection container as the latter is in the process of being removed from the cleaning arrangement by the machine attendant, i.e., before the container can be tilted upwards to a position in which its inlet opening faces upwards.

Cleaning arrangement in an electrophotographic copying machine

An electrostatic copier has a rotatable copy drum and a developing unit which can be inserted and removed from the copier in toto. The developing unit is provided with bearing members which at least partly and loosely embrace the shaft of the copy drum.

An optical copier has a transparent exposure plate which supports a portion of an original document to be copied and exposes the latter to light rays during the copying operation. The transparent plate extends across an opening of a frame, being inwardly offset with respect to a support surface of the frame. A lid is mounted on the frame for pivoting between a closed position in which the lid covers the transparent plate, and fully open position. A marginal portion of the frame holds the lid in its fully open position so that the lid serves to support another portion of the original document. A hinge which mounts the lid on the frame may include a connecting link and two pivots which respectively connect the link to the lid and to the frame. The hinge may be mounted either on the lid or on the frame for an easy detachment therefrom, for instance, by resiliently yieldable bearing blocks which engage with snap action behind an edge portion which surrounds an orifice. The easy detachment may also be achieved by providing bifurcated connecting members whose prongs yieldably embrace and engage an axle.

Arrangement for supporting original documents on an optical copying

An arrangement for transporting toner from a supply to a latent-image developing station of an electrostatic copier. The arrangement includes a rotatable transporting element having a shaft, an eccentric cam spaced from the shaft, a pivot arm pivotable into and out of contact with the cam and a freewheel drive connecting it with the shaft, and an adjustable stop which determines the extent to which the pivot arm can pivot towards the cam.

Toner dispensing device for an electrostatic copier

A drum assembly for an electrostatic copier having a stationary frame comprises a cylindrically tubular drum whose outer surface carries a light-sensitive coating. A pair of rings are snugly engaged with the outer ends of the drum and are mounted via roller bearings on the frame for rotation about a common ring axis. A support sleeve is non-rotatably fixed to the frame between the rings and within the drum and has an outer surface which normally lies out of contact with the drum and only serves to support the drum as it is being fitted into the machine, so as to protect its delicate light-sensitive coating. One of the rings can be removed from the frame so as to allow axial withdrawal of the drum.
