INK CARTRIDGE FOR INK JET PRINTER

摘要

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.
