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 is detachably held by a tank holder having an arc shape portion of a specific curvature. This ink tank has also an arc shape portion of a specific curvature, and the arc center of the arc shape portion of the ink tank is in the same position as the arc center of the arc shape portion of the tank holder only when the ink tank is correctly installed on the tank holder. The ink tank is provided with the movable lever having the engagement nail to engage with the tank holder, and the movable lever is provided with the tongue portion on the upper portion of the engagement nail to be operated when the ink tank is removed from the tank holder, and the arc shape portion of the ink tank is the portion of the arc shape formed for the tongue portion. With the structure thus arranged, it becomes possible to facilitate the user to install the ink tank on the tank holder correctly and reliably without exercising any extra force leading to the damage that may be caused to the ink tank.

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.
