Definitions

  • the invention relates to a developer station for a cartridge provided with an optical fiber drum for a photocopier or a laser printer with a toner container and a magnetic roller connected downstream of the opening of the toner container, in which a frame is used between the toner container and a frame which is detachably connected to it and serves to support the magnetic roller mask is sealed by a peelable film strip sealed window.
  • a developer station of the above type in which the toner container is provided with a circumferential flange which can be connected to the frame for the magnetic roller by means of a plurality of screws distributed over its entire circumference.
  • the large number of screws not only proves to be disadvantageous in that it increases the time required for replacing a toner container, but it is also unsatisfactory because the space required for the screws is comparatively large and prevents the cartridge from being compact.
  • the invention has for its object to provide a developer station of the type under consideration, which enables a quick and easy replacement of the toner container with a compact and inexpensive construction.
  • This object is achieved in that a longitudinal edge of the mask as a substantially V-shaped guide or holding rail for one of the Longitudinal edge of the frame formed flange is formed and the frame is connected to the toner container by means of screws on its longitudinal edge facing away from the guide and holding rail.
  • the developer station according to the invention has the advantage that its guide and holding rail facilitates the assembly of the toner container and frame, since the frame only has to be connected to the toner container by means of screws on its longitudinal edge facing away from the guide and holding rail.
  • the arrangement of the guide and holding rails on the mask keeps the tooling costs required for their production within reasonable limits.
  • the space requirement for the guide and holding rail is ultimately less than the space requirement for a screw flange.
  • the length of the toner container should be greater than the length of the magnetic roller, i.e. in practice have at least the same length as the frame used to support the magnetic roller.
  • the frame is provided with a circumferential foam seal on its support surface facing the mask.
  • 1 is a toner container provided with a filling opening 2 which can be closed by a stopper, not shown.
  • the toner container 1 is trough-like, that is to say open on one side.
  • the open side of the toner container 1 forms a toner discharge opening 4 surrounded by a circumferential flange 3, through which toner can get into the region of a magnet roller 6 mounted in a housing-like frame 5 during operation of a device equipped with the developer station.
  • a mask 7 and a foam seal 8 are arranged between the frame 5 of the magnetic roller 6 and the toner container 1.
  • an adhesive strip 9 coated on both sides is used, which on the one hand ensures a sufficiently firm and tight connection between the mask 7 and the toner container 1, but on the other hand also allows the mask 7 to be replaced.
  • the mask 7 delimits a window 10 which is closed or sealed by a removable film strip 11.
  • the sealing is preferably carried out by welding.
  • the foam seal 8 ensures that, even after the film strip 11 has been removed from the mask 7, the connection point between the toner container 1 and the frame 5 is properly sealed.
  • the toner container 1 When connecting the toner container 1 to the frame 5, one first pushes a flange 12 formed by one of the longitudinal edges of the frame 5 together with a longitudinal edge 13 of the foam seal 8 into a guide and holding rail 15 arranged on the longitudinal edge 14 of the mask 5 and then sets with the help screws 16 provide a tight connection between the frame 5 and the mask 7 previously connected to the toner container 1.
  • the preferably self-tapping screws 16 can be screwed into bores 17 of the flange 3 of the toner container 1.
