Abstract

Disclosed is an ink supply device (8) of an inkjet recording apparatus (10) including a first tank (81) which pools ink which is to be supplied to heads (3), a second tank (82) which is provided in a middle of a path to the heads (3) from the first tank (81), a first ink feed unit (814) which feeds the ink to the second tank (82) from the first tank (81), a second ink feed unit (829) which feeds the ink to the heads side from the second tank (82) and a first ink flow path (811) which connects the first tank (81) and the second tank (82). In the ink supply device (8), an end section of the first ink flow path (811) in the second tank side is connected to the second tank (82) so that the ink flows along an inner wall of the second tank (82).

Description

technical field [0001] The present invention relates to an ink supply device and an ink supply method for supplying ink to an inkjet head included in an inkjet printer. Background technique [0002] An inkjet printer is a recording device capable of forming images on various recording media such as plain paper and plastic sheets. An inkjet printer has an inkjet head that ejects ink from nozzle holes, and can form an image on a recording medium by ejecting fine droplets of ink from the nozzle holes of the inkjet head to the recording medium. [0003] The inkjet head is connected to an ink cartridge storing ink, and ink is supplied to the inkjet head from the ink cartridge. [0004] At this time, if dissolved gas or air bubbles are mixed in the ink, the internal volume will change, which will cause the ink ejection effect of the inkjet head that ejects the liquid droplets to deteriorate. A degassing module for vacuum degassing is provided between the ink heads to remove the ...
