Abstract
A nozzle ink cartridge includes an ink cartridge main body and a first circuit substrate disposed at the ink cartridge main body. The first circuit substrate is configured with, a nozzle circuit and a first interface circuit. A second circuit substrate is disposed on the ink cartridge main body, and configured with a second interface circuit and a third interface circuit, which are electrically connected and disposed on a same side of the ink cartridge main body. A replaceable ink container is contained in an accommodation portion and configured with a first storage circuit and a fourth interface circuit electrically connected to the first storage circuit and the third interface circuit. The first storage circuit at least stores ink amount information of the ink container. The second circuit substrate is further configured with a switching circuit capable of processing signal transmission between the second and third interface circuits.
