PURPOSE: An ink refill device is provided to be compactly and cleanly set by all components of a device received in a box-shaped case in a double structure. CONSTITUTION: An ink refill device (100) includes a box-shaped case (110), an ink container (210), an injector (140), an ink suction line (240), a first check valve (250) and a three-way valve (260), a partition member (290), an ink cartridge mounting support (320), an ink injection line (340), and a second check valve. The ink container is accommodated in one side of the case, and has a lid (220) capable of opening and closing. The ink suction line has one end connected to the lower portion of the ink container so as to be communicated in the ink container, and the other end connected to the inlet (190) of the injector. The first check valve and three-way valve are connected to the middle of the ink suction line and block the back flow of an ink (230). The partition member is installed to vertically partition the inner space of the case so that the ink cartridge mounting support is located in the upper portion of the injector, and the first check valve and the three-way valve. The ink injection line has one end connected to the three-way valve, and the other end connected with the ink cartridge mounting support so as to charge the ink cartridge with the ink supplied to the ink cartridge. |
