The invention relates to an ink cartridge, an ink cartridge set and an ink cartridge determination system. The invention comprises a first signal blocking section and a second signal blocking section, wherein the second signal blocking section is a movable component and is in an initial ink cartridge installation detection position before detection, and the initial ink cartridge installation detection position determines whether or not the second signal blocking section prevents a second signal from passing through the second signal blocking section or changes the path of the second signal. That is to say, different ink cartridges can be distinguished by different initial ink cartridge installation detection positions of the movable second signal blocking section.
