    摘要： An ink jet recording apparatus, which performs printing by ink ejection, comprises a pressure chamber in which ink liquid is filled; a nozzle hole 116 which is formed communicating with the pressure chamber; a piezoelectric element 113 which is formed on the pressure chamber, and deforms the pressure chamber by mechanical expansion and contraction, whereby pressure is generated in the pressure chamber and ink is ejected from the nozzle hole 116; and a dew point control unit 123 which keeps a dew point in an atmosphere of the piezoelectric element 113 and the vicinity of the piezoelectric element 113 at a lower value than a dew point in an environment where the ink jet recording apparatus is set. The dew point control unit 123 comprises a compressor 123a, and an air drier 123b which dries compression gas from this compressor 123a and feeds it to the piezoelectric element 113.

    摘要： An ink jet recording apparatus, which performs printing by ink ejection, includes a pressure chamber in which ink liquid is filled; a nozzle hole (116) which is formed so as to communicate with the pressure chamber; a piezoelectric element (113) which is formed on the pressure chamber, and deforms the pressure chamber by mechanical expansion and contraction, whereby pressure is generated in the pressure chamber and ink is ejected from the nozzle hole (116); and a dew point control unit (123) which maintains a dew point in an atmosphere of the piezoelectric element (113) and the vicinity of the piezoelectric element at a lower value than a dew point in an environment where the ink jet recording apparatus is set. The dew point control unit (123) includes a compressor (123a), and an air drier (123b) which dries compression gas from the compressor (123a) and feeds it to the piezoelectric element.

    摘要： In order to maintain ink supply pressure to a recording head constant while supplying the recording head with ink with an minimum of air entrained therein, the invention provides an ink supplier which comprises a main ink reservoir, a subsidiary ink reservoir connected to the main ink reservoir for replenishment with ink from the main ink reservoir and a means whereby a position head of the ink liquid level in the subsidiary ink reservoir is maintained substantially constant relative to a printing head face of the recording head. Included preferably also are a deaerator associated with the subsidiary ink reservoir for removing air from ink therein and a float floating on ink in the subsidiary ink reservoir. Further, in order for a mechanism that adjusts the position head for ink supply to the recording head to be made light equipped and manufactured at reduced cost, the invention provides an ink supplier that comprises a back pressure reservoir connected between the main ink reservoir and the recording head and adapted to maintain a height of the ink liquid level therein substantially constant against an amount of ink consumption by the recording head and a means for adjusting the back pressure reservoir in its vertical position, thereby adjusting a position head of the ink liquid level in the back pressure reservoir relative to a printing head face of the recording head.
