摘要： A method for standardizing an ink jet recording head is arranged to be capable of utilizing the characteristics of each of recording heads to the maximum, while maintaining the compatibility between them. Particularly, the compatibility is maintained between the novel type recording head whose interior is partitioned into two layers through movable members, and a conventional type recording head. When the conventional type recording head is mounted on a novel type recording apparatus, all the requirements are handled by the novel type recording apparatus side to drive the conventional type recording head under a condition regulated for the conventional type recording head. When the novel type recording head is mounted on a conventional type recording apparatus, it is driven within the capacity of performance of the conventional type recording apparatus. A discriminator for discriminating the kind of mounted recording head is provided for each of the recording apparatuses. In this way, various control operations are attained. When the structure is arranged to use separate recording heads and ink tanks, the compatibility is maintained, while utilizing the difference in characteristics of the novel type recording head and ink, and those of the conventional type recording head and ink to the maximum by means of discriminating one kind of ink from another.

For this method, the fulcrum of the movable member is positioned on the side different from liquid discharging side with respect to the displacement area for the free end of the movable member to be displaceable, and at the same time, the free end thereof is arranged to face the effective bubbling area positioned on the downstream side of the central portion of the length of the effective bubbling area that forms the bubble generating area in the direction of the movable member from the fulcrum to the free end thereof, and a part of the effective bubbling area positioned to face the free end of the movable member on the downstream side of the effective bubbling area is arranged to face the displacement area directly. Thus, the initiation of the displacement of the free end of the movable member is effectuated quickly and reliably, and the pressure exerted by the air bubble creation is led to the discharge port side and the fulcrum side of the movable member sufficiently at the time of bubbling, and the development of air bubble that follows is directed to the discharge port side more reliably and efficiently.
