Abstract
An ink cartridge recharge system includes an ink cartridge mount hole in which an ink cartridge is mounted. The ink cartridge mount hole includes an ink injection part in which an ink injection hole connected to a nozzle of the ink cartridge is formed. A magnetostrictive displacement transducer is connected to the ink injection hole through an ink supply tube and determines the charged amount of ink by sensing displacement of magnetic field due to displacement of an internal float. A positive pressure tank stores high pressure air by a compressor. A bulk cartridge is connected to one side of the magnetostrictive displacement transducer to supply ink to be charged. A negative pressure tank is connected to the ink injection hole of the ink cartridge mount hole through a vacuum tube.
