Abstract
An ink jet recorder includes an ink jet head that is movable in the vertical direction, an ink tank for supplying ink to the head, a detector for detecting the position of the head in the vertical direction, and a moving device for raising and lowering the ink tank. The ink tank moving device changes the vertical position of the ink tank in response to vertical positions of the head detected by the detector. The ink tank moving device is made up of a rack attached to the tank, a pinion gear, and a pinion drive motor. The pressure on the ink supplied to the ink jet head from the ink tank can be made more or less constant, irrespective of the height position of the ink jet head, so that good printing performance can be secured.
