PROCESS CARTRIDGE AND IMAGING DEVICE Russian patent published in 2011 - IPC G03G21/18 

FIELD: physics.

SUBSTANCE: process cartridge is arranged inside imaging device electro photographic unit main assembly. Note here that said main assembly comprises door to move between open and closed positions to open and shut off the opening, first drive element to move together with said door and second drive element to be drive by is drive. Said cartridge comprises electro photographic light sensitive drum, developing roller to develop electrostatic latent image formed on said drum, drum assembly comprising electro graphic light sensitive drum, developing unit comprising developing roller to move relative to drum assembly so that developing roller moves between position of contact with electro photo graphic light sensitive drum and retracted position wherein developing roller is moved from said drum, force take-up device comprising first force take-up section when door moves from open into closed position, and second force take-up element to move from idle position driven by first force take-up element wherein second force tale-up element, occupies extended position to take up second element force to move developing assembly from contact position into retracted position. Note here that extended position is located above expectance position.

EFFECT: reduced sizes, higher reliability.
