Abstract

Apparatus for the clean filling of toner from a container into a developer station reservoir in a non-mechanical printing or copying machine comprises a laterally disposed guide trough having a centering portion at one end and a seating surface disposed adjacent the fill opening of the reservoir at the other end. A pivot recess is disposed between the centering trough and the seating surface to provide a pivot line about which a container can be laterally inverted from an initial upstanding position in the centering trough to a laterally disposed position in the seating surface with the container opening overlying the fill hole. Subsequently, the container is vertically inverted into the fill hole where the discharge end of the container rests against stop pins disposed in the hole. The reservoir hole is provided with a pivotable cover member which is upraised during filling operation and is provided with bracket surfaces which form a mount for the vertically inverted container, allowing the container to be shaken without risking that the container will slip out of the fill hole.
