Claims

[Claims for Utility Model Registration] 1. An inkjet recording unit is constructed by stacking another plate-like member on a plate-shaped tank casing having an ink chamber inside, and filters the ink passing through the ink chamber. The remaining ink is energized by an ink pressure pump, the pulsation is damped by an accumulator, and the ink is supplied to the inkjet recording head.
An inkjet recording device that sequentially records on paper by ejecting ink from the recording head, the inkjet recording device comprising: the accumulator disposed below the tank casing. 2. A plurality of ink chambers are arranged in a plurality of planes in the tank casing, a plate-shaped base member is superimposed on the lower side of the tank casing, and an ink flow path connecting the ink chambers is attached to the base member, The inkjet recording apparatus according to claim 1, comprising the accumulator. 3. The inkjet according to claim 2 of the utility model registration claim, wherein the base member is provided with a liquid chamber that opens toward the bottom thereof, and a diaphragm is attached to close the opening of the liquid chamber to constitute the accumulator. Recording device. 4. The inkjet recording apparatus according to claim 1, wherein the inkjet recording unit is mounted on a carriage, and the inkjet recording unit sequentially performs recording while the carriage is moved along a platen.
