Abstract: An ink jet recording head capable of separating or coupling ink tanks from or with the head comprises a recording device substrate having a plurality of recording devices thereon for discharging ink, a wiring device for giving electrical recording signals to the recording device substrate, an ink supply member for supplying ink to the recording device substrate, and a filter member for removing dust particles or the like in ink. This recording unit is provided with all the functions of discharging ink, and coupled with a holder member having only the function of holding and fixing ink tanks. With the structure thus arranged, it becomes unnecessary to connect ink supply paths as in the conventional art, hence eliminating the provision of sealing members. The number of parts is made smaller, while making it possible to carry out inspection of heads only in accordance with the recording units, which significantly contributes to simplifying manufacture and providing highly reliable heads at lower costs.

Abstract: An ink tank is to be held detachably on a tank holder provided with a movable lever having a first engaging pawl to engage with a first engagement hole provided for one side wall of the tank holder, and a second engaging pawl to engage with a second engagement hole provided for side wall opposite to the one side wall having the first engagement hole of the tank holder. For this ink tank, the distance S between the outer side face of the base portion of the movable lever of the ink tank and the leading end of the second engaging pawl is set to be larger than the distance between the inner wall faces of the side wall having the first engagement hole of the tank holder and the side wall having the second engagement hole. With the structure thus arranged, unless the ink tank is kept in the normal posture, the ink tank is not allowed to enter the tank holder, hence enabling the user to recognize it easily and prompt him to operate the installation of the ink tank correctly.

Abstract: An ink tank holding member (13) for holding ink tanks containing ink is made freely attachable and detachable, at the same time, having ink lead-out members for leading out ink from ink supply ports provided for the ink tanks. For this ink tank holding member, gap complementary members (17) are made mountable to complement the difference in shapes of ink tanks to be installed on the holding member. With the structure thus arranged, it becomes possible to use the ink tank holding member for each of the cartridges commonly, hence attempting the common use of parts, at the same time, preventing effectively the ink tanks from being inclined by the provision of the gap complementary members, thus enhancing the reliability of ink supply portion, as well as preventing the degradation of performance that may be caused by erroneous insertion of ink tanks.

Abstract: A liquid ejection printing apparatus can certainly and quickly perform preliminary ejection. The liquid ejection printing apparatus ejects droplet of a liquid state printing material through a printing head (10) to a medium to be printed for depositing the printing material to perform printing. The liquid ejection printing apparatus performs preliminary ejection upon the onset of power supply (13) and/or prior to initiation of printing with varying a drive frequency of the printing head during the preliminary ejection.
