In order to ensure that the conductive contacts on the chip can be reliably connected to the printer, an elastic handle is disposed on the first side wall of the ink cartridge main body and the second side wall opposite thereto, and the elastic handle is located along the insertion direction of the ink cartridge. The upper position is higher than the position of the chip fixing portion. When the ink cartridge is installed in the printer, the buckle on the elastic handle elastically engages in the corresponding latch of the printer, and the ink cartridge is fixed in the printer on the one hand, and the conductive contact on the chip can be reliably ensured on the other hand. Electrically connected to the corresponding contacts on the printer. The above solution has the following disadvantages, since the elastic handle of the ink cartridge extends from the middle of the main body of the ink cartridge, the support arm is short, the range of elastic deformation is small, and a large force is required to install and remove the ink cartridge to make the buckle and the buckle Relief, and the reliability of the ink cartridge fixing is also poor. Disclosure of the Invention An object of the present invention is to provide an ink cartridge which can be reliably fixed to a printing apparatus, ensure electrical connection, and can be easily mounted or taken out. To achieve the above object, an ink cartridge provided by the present invention includes an ink cartridge main body for accommodating ink, and the ink cartridge main body is surrounded by a top wall, front and rear walls, first and second side walls and a bottom wall, is located on the ink cartridge main body and is used for The ink is discharged from the ink outlet outside the main body of the ink cartridge, and is located at a chip mounting portion on one side wall of the ink cartridge main body.

Confirmation In the elastic handle that is engaged with the printer, a recess is provided on a side wall of the ink cartridge main body near the top wall, and the elastic handle extends from the recess and extends toward the bottom wall. Another ink cartridge according to the present invention includes an ink cartridge main body for accommodating ink, the ink cartridge main body being surrounded by a top wall, front and rear walls, first and second side walls, and a bottom wall, located on the ink cartridge main body and used for ejecting ink from the ink cartridge An ink outlet outside the main body, a chip mounting portion on one side wall of the ink cartridge main body, and an elastic handle for engaging with the printer. A recess is provided on a side wall of the ink cartridge main body near the bottom wall, and the elastic handle extends from the concave portion Come out and extend towards the top wall.
