ABSTRACT:
An ink cartridge and loading mechanism for ink cartridge are provided. A mounting structure is formed on one side of the ink cartridge. The loading mechanism includes a loading section, a gear set, and a lever set. The loading section has lateral walls and a deck. The gear set is located on one of the lateral walls and has a spur gear and a pinion gear engaged to each other. The spur gear has at least one protrusion inserted into the mounting structure of the ink cartridge. The lever set is connected to the pinion gear for driving the gear set. Therefore, the gear set may change the torque of the protrusion. Then the protrusion may be coupled with the mounting structure to suppress the ink cartridge downward, or to lift the ink cartridge to be removed.
