TONER CARTRIDGE WITH COUNTER Russian patent published in 2016 - IPC G03G15/08 

FIELD: printing industry.

SUBSTANCE: invention relates a fast-extracted toner cartridge, which is installed in electronic device for photographic display, for example, a laser printer, copier or fax machine, wherein toner cartridge is fitted with a counter which can be used in conjunction with a detector of photographic display device for obtaining information on whether toner cartridge is installed in photographic display device is new and whether to restart counter of cartridge life. Present group of inventions includes a toner cartridge with a counter, comprising a cartridge housing for storing developer, as well as electronic device for photographic display comprising said toner cartridge and an information receiving mechanism. Toner cartridge with counter comprises a cartridge housing for storing a developer, a counter and a counter drive element, wherein counter has a protrusion that moves under influence of driving of counter mechanism of actuator from a first position in which protrusion is in contact with contact lever of electronic device for photographic display a second position in which protrusion is not in contact with contact lever of electronic device of photographic display thereby producing count of toner cartridge, toner cartridge with counter is characterised in that drive of counter element drives protrusion moving in direction perpendicular to side wall of cartridge housing, wherein counter comprises a rotating element and a stationary element, wherein rotating element is rotatable relative to toner cartridge, wherein on one of rotating element and a stationary element is fixed a support base and other of rotating element and a stationary element has a groove corresponding to support base, rotating element has a protrusion, and rotating element moves closer to stationary element.

EFFECT: technical result consists in ensuring high accuracy, simplification of design, as well as providing convenience and reliability.
