CARTRIDGE Russian patent published in 2017 - IPC G03B41/00 

FIELD: printing industry.

SUBSTANCE: cartridge includes a housing with the first side wall and the second side wall opposite to the first side wall in the longitudinal direction, a passive unit configured to receive the driving force from the outside, wherein the passive unit being mounted in the housing and rotatable about the first axial line, and a detectable body mounted on the first side wall and including a detectable part configured to be detected by the detecting unit, wherein the detectable body is configured to extend outwardly in the longitudinal direction with respect to the first side wall and to be drawn inwardly in the longitudinal direction with respect to the first side wall. The detectable body is movable from the first position, where the distance in the direction of movement between the detectable body and the first side wall is the first distance, to the second position, where the distance in the direction of movement between the detectable body and the first side wall is the second distance, which is greater than the first distance, and to the third position, where the distance in the direction of movement between the detectable body and the first side wall is the third distance, which is smaller than the second distance.

EFFECT: prevention of delays in the installation or removal of the cartridge caused by the detectable part and occurring inside the main housing of the device, and prevention of damage to the detected part, for example, due to collision with other elements, when the cartridge is removed from the device main housing.
