After the ink cartridge 100 is mounted to the apparatus, when the remaining amount of ink in the ink cartridge 100 is sufficient, the floating member 65 moves upward along the guiding member 62 under the action of buoyancy, the second magnetic member 653 in the second connecting portion 651 generates a repulsive force with the first magnetic member 645 in the first connecting portion 643, so that the first connecting portion 643 drives the light shielding member 64 to swing counterclockwise around the mounting portion 612, so that the light shielding portion 642 moves to a first position where the light shielding portion 643 shields the detection light, the light shielding portion 642 is close to the first blocking portion 613, the first connecting portion is close to the second inclined surface 616, the detection light in the apparatus is shielded from passing through the ink cartridge 100 at this time, and the apparatus cannot receive the detection light, so that the apparatus can detect that the remaining amount of ink in the mounted ink cartridge 100 is sufficient, and can perform a printing operation.

When the ink in the ink cartridge 100 is consumed and the remaining amount is insufficient, the floating member 65 will gradually descend along the guiding member 62 along with the consumption of the ink, and the second connecting portion 651 is simultaneously far away from the first connecting portion 643 to gradually reduce the repulsive force therebetween, so that the first connecting portion 643 drives the light shielding member 64 to swing clockwise around the mounting portion 612 under the action of gravity, so as to move the light shielding portion 642 to the second position where the light shielding portion 642 does not shield the detection light, the light shielding portion 642 is close to the second blocking portion 614, and the first connecting portion 643 is far away from the second inclined surface 616, at this time, the detection light in the apparatus smoothly passes through the ink cartridge 100, and the apparatus receives the detection light, so that the apparatus detects that the remaining amount of the ink in the ink cartridge 100 is insufficient, and prompts the user to replenish the ink.
