Abstract

The toner cassette 10 is installed over a hopper 11 which communicates with the toner dispenser 12 of the develop~ ment system (not shown) The toner cassette includes a pair of pivotally supported bottom plates 13 and 14 which are normally biased toward their closed positions as in the left hand figure. As the cassette 10 is lowered onto the hopper 11, triangular members 15 located inside the hopper at each end engage the curved lips of the bottom plates 13 and 14, and pivot them open as in the right hand figure. The toner then flows by gravity into the hopper 11 and dispenser 12 for dispensing into the development system.

The toner cassette 10 is installed over a hopper 11 which
communicates with the toner dispenser 12 of the develop~
ment system (not shown) The toner cassette includes a
pair of pivotally supported bottom plates 13 and 14 which
are normally biased toward their closed positions as in the
left hand figure. As the cassette 10 is lowered onto the
hopper 11, triangular members 15 located inside the hopper
at each end engage the curved lips of the bottom plates
13 and 14, and pivot them open as in the right hand figure.
The toner then flows by gravity into the hopper 11 and
dispenser 12 for dispensing into the development system.

As the machine cycles, a cam 16 rotates in the direction of
the arrow and acts upon the triangular members 15 inside
the hopper 11 to move them up and down. The bottom plates
13 and 14 are stroked by the inclined portions of the triangular members 15 to provide agitation of the toner in
the cassette 10 and hopper 11, Pins 17 supported by the
pivotal bottom plates 13 and 14 aid in the elimination of
