Abstract: This invention relates to an toner cartridge to dispense toner to a developing system in a photocopying device. The cartridge has a primary baffle thereby forming a main chamber and a dispensing chamber. The dispensing chamber is divided into a primary dispensing chamber and a secondary dispensing chamber by a secondary baffle. Apertures are formed in the container adjacent to the secondary dispensing baffle. The cartridge is designed to be rotated in one direction to fill the secondary dispensing chamber with toner, and then rotated in an opposite direction to dispense the toner from the secondary dispensing chamber through the apertures.

Abstract: This invention relates to a cross-mixer for a developer system of a photocopier, particularly one with a two component development system, which mixes the developer mixture (1) to assure uniform lateral distribution of the toner, (2) to assure uniform concentration of the toner mixture and (3) to triboelectrically charge the developer mixture.Adjacently offset rows of V-shaped baffles successively divide and intermix the developer mixture. Angled lifting plates interposed between successive rows of baffles scoop and lift the mixture so as to triboelectrically charge the same.

Abstract: A stacking apparatus for a reproduction machine which can accommodate media sheets as greatly different sizes. An intermittent driving device is used so as to alterantely buckle and relax the sheet media thereby urging the sheet into various recesses which are formed in the apparatus so as to engage sheet media of various sizes.

Abstract: This invention relates to a feed device which automatically straightens sheets prior to their being fed.A nudge wheel feeds the paper into the apparatus against a registration gate thereby straightening the sheet.At the appropriate time, a solenoid actuated clutch initiates a mechanically sequenced series of events which raise a set of feed tires so as to pinch (hold and secure) the previously straightened sheet, lower the registration gate out of the paper path, and start the feed tires and allow the sheet to be fed.At a second appropriate time after the sheet has been fed, the solenoid clutch is de-energized. Stored energy in a spring is used to mechanically reverse the sequence, whereby the feed tires are lowered out of the paper path and the registration gate is raised up into the paper path, preparatory to the next sheet.
