Abstract
The invention relates to a cartridge for ink-jet printer, comprising a cartridge body, a protective cover moving relatively to the cartridge body under pressure, a detection mechanism for cartridge and a detection mechanism for remaining ink volume, wherein the detection mechanism for cartridge includes the first and second detecting units respectively matching to the first and second sensors on the printer. The said second detecting unit includes a shelter unit, a fixed shaft set on the cartridge body, a sliding shaft on the protective cover and a reset unit of the shelter unit, wherein the shelter unit connects with the rotating shaft of the fixed shaft, rotates around the fixed shaft under the pressure of the sliding shaft and resets together with the protective cover under the effect of the reset unit of the shelter unit. It is the shelter unit rather than the movable lever at the middle of the detection mechanism for remaining ink volume that finally shelters from the light emitted by the emission unit of the second sensor, so it will not be influenced by remaining ink volume.
