REPLACEMENT BLOCK FOR ELECTROPHOTOGRAPHIC IMAGE FORMING DEVICE HAVING LATCH MECHANISM Russian patent published in 2017 - IPC G03G15/08 

FIELD: physics.

SUBSTANCE: claimed group of inventions includes replacement blocks for an electrophotographic image forming device comprising: an elongated body extending along the longitudinal dimension between the front side and the back side of the body. The body further includes the first side, the second side, an upper side, and a lower side. The body has a toner storage tank, a drive element on the rear side of the body that is not overlapped to obtain rotational power, when the replacement block is mounted in the image forming device, an electrical contact on the rear of the body not overlapped to make contact with the corresponding electrical contact, when the replacement block is mounted in the image forming device. The drive element and the electrical contact are arranged to sense the deflection force in the forward direction toward the front side of the body along the longitudinal dimension, the latch grip on the first side of the body being arranged to receive the corresponding latch, when the replacement block is mounted in the image forming device to prevent movement of the body in the forward direction along the longitudinal dimension, the latch actuator on the front side of the body, which is configured to be replaced relative to the body between the source position and the release position, and the releasing handle on the front side of the body, not overlapped for capture by the user, operatively connected to the latch actuator, so that the actuation of the releasing handle causes the latch actuator movement from the source position to the release position for disengagement of the body from the image forming device.

EFFECT: ensuring accurate alignment of the cartridge, and relatively simple insertion of the cartridge into and out of the image forming device.
