PURPOSE:To perform replacement work of an ink tank readily, in a device that supplies ink to ink jet heads, by providing a mounting terminal for a pressurizing means which pressurizes ink chambers in the ink chambers. CONSTITUTION:The ink tank 201 is divided by a separating wall 328 into the ink chambers 202 and 203. The lower parts of the ink chambers are communicated by a communicating pipe 204 through a valve 205. Ink introducing holes 210, 210', 211, 211', which are communicated to ink jet heads 233 and 233', are provided in the ink chambers 202 and 203. A hole 240 is provided at the upper part of the ink chamber 202, and connected to a pressurizing pump 207 through a connecting pipe 239 and a pressuring pump mounting terminal 206. Since the terminal 206 is connected to a pressurizing pump connecting pipe 242 at one end and constituted by an elastic body, the connecting pipe 242 can be readily attached and detached, and the state of hermetical sealing can be maintained. |
