    Abstract: A liquid jet recording apparatus comprises a first ink tank for storing an amount of ink, a second ink tank for receiving the ink from said first tank through a feed tube, a recording head for jetting the ink fed from said second tank, and a carriage for reciprocally moving said second ink tank and recording head together, characterized in that at least a portion of said feed tube is lengthwise moved following the movement of said second ink tank along the course of its reciprocation and thereby the ink is fed to said second ink tank from said first ink tank.

    Abstract: An ink jet recording apparatus has a recording head for discharging ink and effecting recording, a recording flow path communicating the recording head with one end of a first ink tank, a pump side flow path communicating the first ink tank with the recording head through a pump and, together with the recording flow path, constituting an ink circulation path through the head and the first ink tank, and a secnd ink tank for supplying ink to the first ink tank. Normally open electrical opening-closing means (FIG. 11) are provided in the recording flow path and in a tube for opening the first ink tank to atmosphere. Another normally open electrical opening-closing means and a check valve permitting the passage of ink from the pump only to the recording head, this latter opening-closing means and the check valve being interposed in series in the pump side flow path between the pump and the recording head. The apparatus also may include an overflow sensor (FIGS. 9 and 10) for detecting the amount of ink that has overflowed from the first ink tank and a water hammer damper (FIG. 14) that absorbs fluid shocks in the pump side flow path. The second ink tank may have excised portions (FIGS. 15, 16 and 18) to ensure that color ink tanks are properly mounted to the apparatus.

    Abstract: A method of making an ink jet head with an orifice plate having an orifice extending therethrough for ink ejection involves the steps of adhering a photosensitive plate to the ink jet head to cover the outlet of a liquid passageway in the head, aligning a pattern mask with the ink passageway, exposing the photosensitive plate in-situ to radiation through the pattern mask, and removing portions of the photosensitive plate in accordance with the radiation pattern to form in the photosensitive plate an orifice aligned with the outlet.

    Abstract: PURPOSE:To enable a recorder to be directly fixed on a CRT and to be installed even on a slant face for the effective use of an installation place for the recorder. CONSTITUTION:When a recorder 5 is used for a desktop type personal computer, the recorder 5 is placed on a CRT 11 for the purpose of effectively using a space. Two fixing members 12 are each pulled out of a containing part of the recorder 5 by a specific amount. Presser parts 12a in a folded state are each erected. The presser parts 12a are each pressed against the side faces of the CRT 11 by a resilient member not shown by a figure. In this manner, the recorder 5 can be fixed to the CRT 11.
