Problems solved by technology

[0015] However, in the inkjet recording device described in the above document 3, since the volume of the sub tank is small, it is difficult to control the pressure, and the accuracy cannot be said to be excellent.
[0016] In addition, due to the need to install a pressure measuring device, an air suction device and an air supply pump in the auxiliary tank, the structure becomes complicated and the weight of the auxiliary tank is increased
Therefore, it is not very efficient in moving the sub-tank
[0017] Moreover, the auxiliary box itself becomes larger, and there is also a disadvantage that additional space is required for installation.

Abstract

An inkjet recording apparatus which can make a distribution tank compact and has excellent pressure-control precision is provided. The present invention is provided with an inkjet portion A having a recording head 11 for applying ink to a recording medium 1 and a distribution tank 12 for supplying ink to the recording head 11, an ink supply means B having a main tank 21 for supplying ink to the distribution tank 12, and an air supply means C having an air chamber 31 communicating with a space 12a in the distribution tank 12 and a pressure adjustment mechanism provided on the air chamber 31 via a solenoid valve, where the pressure of the space 12a and the internal pressure of the air chamber 31 are equal to each other.

Description

technical field [0001] The present invention relates to an inkjet recording device and a control method thereof, and more specifically, to a pressure control type inkjet recording device capable of making a distribution box small and compact and having excellent pressure adjustment accuracy. Background technique [0002] Inkjet recording devices are used in many fields because they can record patterns or characters continuously and at high speed based on predetermined image data. [0003] As such an inkjet recording apparatus, for example, an inkjet recording apparatus including a back pressure tank, a distribution tank, an ink opening and closing solenoid valve, and a recording head is known (for example, refer to Patent Document 1 or 2). [0004] However, since ink is supplied by utilizing the head difference between the liquid level of the back pressure tank and the recording head in these inkjet recording devices, there are certain restrictions on the positional relation...
