Abstract: The present invention relates to an ink-cartridge loading/unloading apparatus used in various devices onto which an ink-cartridge is capable of minimizing damage of a flexible printed wiring board of the ink-cartridge. The ink-cartridge loading/unloading apparatus according to the present invention comprises a vertically extending main body having a support portion; a mounting part connected to the front surface of the main body; and a coupling part connecting the main body and the mounting part. A metal coupling bar or a magnetic substance inserted in a coupling bar is attached to an electromagnet provided in a side of the main body, whereby the mounting part is coupled to the main body. The mounting part is released from a coupled state by pressing a button bar with an external force, and an elastic means is further provided between the mounting part and the main body.

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.

Abstract: Disclosed herein is an ink cartridge refill system for inkjet printers and a method of refilling ink cartridges using the system. The refill system includes a vacuum pump to supply ink from an ink tank into a cylinder and to forcibly draw ink from an ink cartridge, as well as an air compression pump to generate a compression force to inject ink from the cylinder into the ink cartridge through the nozzle of the cartridge. The cylinder is connected at the inlet end thereof to both the air compression pump and the vacuum pump, and is connected at the outlet end to both the ink tank and the ink cartridge. Both a compression pump line and a first vacuum pump line which pass through the cylinder are connected to the nozzle of the cartridge through an ink supply hose. The vacuum pump includes a second vacuum pump line directly connected to the ink cartridge, as is the first vacuum pump line passing through the cylinder.

Abstract: An ink recharge system capable of repeatedly charging a proper amount of ink in an ink cartridge using magnetostrictive displacement transducers and a method of recharging ink in the ink cartridge are provided. The ink cartridge recharge system for an inkjet printer includes a compressor and a positive pressure tank providing compression force for supplying the ink stored in magnetostrictive displacement transducers to an ink cartridge, magnetostrictive displacement transducers for charging a proper amount of ink, a vacuum pump and a negative pressure tank for making the inside of the ink cartridge vacuous, and a pneumatic tube divided from a positive pressure tank and a vacuum tube divided from a negative pressure tank connected to pneumatic regulators of the magnetostrictive displacement transducers through the pneumatic solenoid valve.
