Abstract: A seal rubber for use in print heads, ink jet printing apparatuses, or the like that enables print heads or the like to be appropriately manufactured while preventing the seal rubbers from sticking mutually, is provided. More specifically, a seal rubber (H1800) provided in a joint section between a print head and an ink tank has a roughened surface for an appropriate surface roughness. Thus, even when a parts feeder is used to supply a large number of mixed seal rubbers during manufacture of print heads, the seal rubbers can be prevented from sticking mutually and can be properly separated for supply.

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: 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.
