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 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: PROBLEM TO BE SOLVED: To manufacture a recording head or the like in good manners without causing a seal rubber used in the recording head, an ink jet printer or the like to stick. SOLUTION: A satin finished surface with appropriate roughness is applied on a surface of a seal rubber H1800 provided on a joint with an ink tank of a recording head. Thus, even when numerous seal rubbers are supplied in a mixed manner to a part feeder during manufacturing of the recording head, they can be prevented from sticking to one another, whereby individual seal rubbers can be supplied well separately.

Abstract: PROBLEM TO BE SOLVED: To facilitate unsealing operation by providing means for coupling a liquid container and a cap with a plurality of protrusions formed oppositely to the supply opening of the liquid container in the diametral direction, and a plurality of holes to be fitted with the protrusions made in the cap thereby reducing the unsealing force of the cap. SOLUTION: The liquid holder comprises a cap 1, a container 10 for containing liquid, e.g. ink, and means for coupling the cap 1 and the liquid container 10 wherein the cap 1 covers the supply opening 13 of the liquid container 10. The coupling means comprises a plurality of protrusions, i.e., caulking ribs 15, 16, formed oppositely to the supply opening 13 of the liquid container 10 in the diametral direction, and a plurality of holes 5, 6 to be fitted with the caulking ribs 15, 16 made in the cap 1. The liquid holder further comprises a handle 3 constituting a lever-like operating part for uncoupling the coupling means by turning the cap 1.
