Referring to fig. 3 to 6, a second guiding groove 402 is formed in the mounting portion 400, a guiding protrusion 305 that forms guiding fit with the second guiding groove 402 is formed on the driving assembly 300, and a surface of the guiding protrusion 305 is an inclined surface and is pressed against the second guiding groove 402, so that the insertion of the cartridge body 100 can be guided, and the movement of the first plate 306 can be guided.

Example two

In this embodiment, as shown in fig. 11 to 13, the ink amount detecting member 105 is disposed on the third surface 100c of the ink cartridge main body 100 and is farther from the ink cartridge mounting portion 400 than the light shielding member 106, and correspondingly, the second optical sensor 406 in the ink cartridge mounting portion 400 is also changed in position and disposed on the top surface of the ink cartridge mounting portion 400, and the ink amount detecting member 105 is configured to attenuate the second detection light emitted from the second optical sensor 406 in the ink cartridge mounting portion 400 to detect the remaining amount of ink in the ink cartridge main body 100. When the ink cartridge is mounted to the mounting portion 400 of the ink jet printer, the second optical sensor 406 in the mounting portion 400 emits light in the X-axis direction, and since the ink amount detecting member 105 is positioned between the light emitter and the light receiver of the second optical sensor 406 when mounted to the mounting portion 400, the light emitted from the second optical sensor 406 can be blocked or attenuated, and by detecting a change in the intensity state of the light received by the light receiver side, it is possible to detect whether the amount of ink in the ink cartridge is less than a predetermined ink amount.

With continued reference to fig. 11 to 13, the first surface 100a of the ink cartridge main body 100 is provided with a recess 109, the chip board 104 is provided on the top surface of the recess 109, a stopper 408 is provided in the cartridge mounting portion 400 at a position corresponding to the recess 109, and when the ink cartridge is mounted to the mounting portion 400 of the ink jet printer, the stopper 408 extends into the recess 109 to achieve positioning.

When the ink supply assembly 200 is in the first posture, along the Y-axis direction, i.e. the ink cartridge mounting direction, the distance between the chip board 104 and the nozzle of the ink supply tube 203 in the ink supply assembly 200 is less than or equal to the distance between the nozzle of the ink supply tube 203 in the ink supply assembly 200 and the ink amount detection piece 105, so that the chip generated by the chip board 104 can be prevented from polluting the nozzle of the ink supply tube 203 and affecting the ink circulation.
