CARTRIDGE WITH TONER HAVING SHELL-AND-CORE ELEMENTS MOVING INTO MESH FOR DEVELOPING UNIT SHUTTER ACTUATION Russian patent published in 2017 - IPC G03G15/06 

FIELD: printing industry.

SUBSTANCE: group of inventions includes cartridges versions. Moreover, according to one of the claimed versions the cartridge includes a housing with a front, back, top, bottom and a pair of side faces, wherein the housing has a reservoir for toner storing, discharge opening on the front face of the housing, facing the bottom of the housing, for the toner transferring from the reservoir to a developing unit through an inlet in the developing unit, wherein the outlet is located on the front face of the housing closer to the first side face of the pair of side faces and inclined moving into mesh element protruding from the front face of the housing, the inclined moving into mesh element is distanced from the housing bottom face from the outlet and is distanced from the second face of the pair of side faces from the discharge opening, the inclined moving into mesh element has a front surface which protrudes forward from the front housing surface when the noted front surface moves up along the housing front face.

EFFECT: providing of the toner ejection eliminating from the developing unit when removing the cartridge with toner, ensuring precise positioning of the developing unit relative to the corresponding photoconductive drum, providing of precise timing of the valve opening and closing at the inlet of the developing unit relative to the insertion and extraction of the cartridge with toner, as well as relative to the respective shutter opening and closing at the outlet of the cartridge with toner, providing reliable shutter opening and closing at the outlet of the cartridge with toner and the shutter at the inlet of the developing unit, when inserting and extracting during the life of the components and on the whole range of parts and cartridge insertion trajectories tolerances.
