Abstract: An ink cartridge and a printing apparatus using the same. The ink cartridge includes an ink cartridge body, a chip and a chip holder, and the chip is fixed on the chip holder; when the ink cartridge is installed on the printer along an installation direction, the printer may drive the chip holder to linearly move along a top surface of the ink cartridge body, the chip holder is located at a first position before linearly moving and located at a second position after linearly moving; the chip at the first position is closer to the top surface of the ink cartridge body than at the second position, and when the chip holder is at the second position, the chip abuts against the stylus. The ink cartridge and printing apparatus achieve a higher stability of the electrical connection of the chip and the stylus in a printer.

Abstract: An ink cartridge including a cartridge body, a recess part, a positioning part and a chip disposed in the recess part, where the cartridge body includes an ink accommodating chamber for storing ink, the recess part is disposed on an upper side of the cartridge body and includes a side wall, at least a portion of the side wall is configured to limit a relative position between the ink cartridge and the image forming device in a first direction; the positioning part is disposed above the side wall, and in a second direction, at least a portion of the positioning part is located on a rear end side of the chip and is configured to limit the relative position between the ink cartridge and the image forming device in a third direction.

Abstract: Disclosed is an ink cartridge (1) for an ink jet printer, which is detachably mounted to a cartridge mounting part (100) of the ink jet printer, a convex part (104) is provided in the cartridge mounting part (100). The ink cartridge (1) includes an ink storage chamber (11); an ink supply port (14); a first detecting mechanism (21); a movable member (30); and a second detecting mechanism (40) that is linked with the movable member (30), and the second detecting mechanism (40) can move up and down reciprocatively in a direction perpendicular to a direction in which the ink cartridge (1) is mounted. Using this ink cartridge prevents the problem of inaccurate detection caused by using a lever to detect whether the ink cartridge has been mounted in place.
