Definitions

  • a copying apparatus is contained within a housing and includes a charging unit, a surface element for positioning individual sheets of copying paper in an exposure station, and a developing device containing developing media.
  • a number of pairs of rollers are positioned in the housing for conveying individual sheets of copying paper through the copying apparatus.
  • the housing includes a number of openable covers, preferably hinged to the housing, for gaining access to the interior of the apparatus.
  • Each pair of rollers has one driven roller secured within the housing and the other roller is movably mounted within the housing. Relative to the housing, the driven rollers are spaced inwardly from the movably mounted rollers.
  • the charging units, surface element and developing device can be removed from the housing along with the movably mounted rollers associated with them for affording access to the driven rollers.
  • the path of the copying paper through the housing has a U-shaped configuration with the legs of the U extending horizontally.
  • this object is realized in that with regard to the transport means the paper travel LII is rendered accessible by means of the drawer-like or flap-like construction and arrangement of all units arranged therein or thereon, whilst at least one roller of several pairs of transport rollers is fixed in the housing.
  • the frame may be made in one part and the precision of the mutual arrangement of the unit is assured whilst the detachable arrangement of individual units renders some or all sections of the paper travel accessible, but the fixed arrangement of a driven roller of a pair of transport rollers ensures simultaneously the accurate positioning and actuation of the detachable units after their insertion.
  • the paper travel inside the housing has substantially the shape of a U lying on its side, of which one leg extends parallel to the upper side of the housing and starts with the stack holder arranged thereunder, whilst a vertical, center section of the U shaped travel contains a structural element with rollers and possibly a picture platform, and the lower leg of the U shaped travel contains the developing device and the fusing device in front of a delivery arrangement with transport rollers.
  • This arrangement makes possible an advantageous compact construction with a part of the exposure channel extending between the legs, whilst the paper travel extends always within the zone of parts of the housing walls or of the housing bottom.
  • the housing cover plate is adapted to be opened after the manner of a flap above the switching means and the charging device, and the end face of the housing, alongside which the center section of the U shaped travel is arranged, has a door. It should be mentioned that the housing surrounds the frame.
  • the switching means and the charging device are constructed as box-shaped modules and mounted detachable in profiles open towards the top, wherein the modules have at least in one end wall resiliently actuated contact members which engage fixed contacts in an assembly wall when the module is fitted.
  • the switching off takes place already when the housing is opened, by means of a safety switch in the circuit. No special contact connections need be made during the fitting because the connections are automatically closed by the contact members. In addition, this arrangement ensures the correct insertion since otherwise the connections are not established.
  • the unit associated with the platform is fixed detachably by a tensioning device and may be withdrawn in the direction parallel to the legs of the U- shaped travel. It is here an advantage that this module is arranged behind a door on the vertical section of the U-shaped travel. It should be taken into consideration that this unit of the platform also comprises pairs of transport rollers wherein preferably the movement of the movable unit is perpendicular to the movement of the copying sheet.
  • the mounting walls have centering profiles and the unit corresponding mating profiles extending in the direction of extraction and both sides of the unit are provided with holdinglevers with bent arms adapted to engage behind pins on the mounting walls and/or the associated part of the platform.
  • the arms have preferably wedge-shaped working surfaces.
  • the invention also includes an elastic construction of the arms and a bend such that the levers pass beyond dead center when the closure is made. In this way, the withdrawable module is automatically secured.
  • the levers serve only as fixing means and the resulting forces can have no effect in a translatory displacement of this unit.
  • the developing device is mounted as a drawer-like unit with its inlet under the platform and may be withdrawn as a whole after opening the door wherein a pair of transport rollers associated with a platform unit forms the inlet roller pair into the developing device and behind its outlet under a downwardly offset step there is arranged a further pair of transport rollers acting as outlet rollers.
  • a pair of transport rollers associated with a platform unit forms the inlet roller pair into the developing device and behind its outlet under a downwardly offset step there is arranged a further pair of transport rollers acting as outlet rollers.
  • the invention therefore, comprises also a pivotable partition between a chamber for the developing device and the delivery device with at least one pair of transport rollers, wherein the partition forms a guide element between the pair of transport rollers at the outlet of the developing device and the lower pair of transport rollers of the delivery device and wherein the partition is pivotable about hinges.
  • this guide element mounted diagonally to the run of the paper, a good insulation of the chamber with the developing device is achieved.
  • a flow of cooling air flows through the intermediate space. After withdrawing the developing device module, the pivotability makes it possible to reach through the free space into further transport means in the zone of the fusing device.
  • the partition consists of two wall sections of which one extends obliquely as guide element over the entire width of the guide path, and has in its upper zone an arm directed towards the developing device, whilst the other wall section forms a hinged defining wall for the chamber of the developing device and is a supporting element of smaller width, the upper end of which has a recess adapted to receive the arm of the other wall section.
  • the section forming the guide element can be raised and the other wall section can be lowered, enabling the first section to be folded over.
  • a defined position is achieved in that the wall section acting as guide element has a hinge above its lower edge and the mating hinge is provided on a raised portion of the housing bottom which continues in an oblique section corresponding to the position of the raised wall section.
  • the delivery device is a plug-in plate adapted to be pulled out at the end of the leg of the U-shaped path through a hole in the housing, and a freely revolving roller of the at least one pair of transport rollers of the delivery device is so arranged on the plug-in plate that in the plugged in position of the plate it makes contact with a driven transport roller firmly mounted in the housing.
  • the plug-in plate is fixed in an easily detachable manner.
