摘要： In an ink jet printing apparatus wherein an ink ejection head is loaded on a carriage and, while the carriage moves relative to a sheet of paper, ink droplets are ejected from the head to be charged and deflected to impinge on the sheet of paper, a shape or a position of a conductive member carried on the carriage is varied to develop an electric field which is asymmetrical with respect to a predetermined plane in which charged ink droplets coming out from a charging electrode are to be deflected. The conductive member is constituted by a cover of the carriage, a shield plate, a gutter, a compensating electrode plate, a deflection electrode or the like.

摘要： A first ultrasonic transducer is normally energized so that the ink jet normally emerging through a nozzle of an ink manifold containing the pressurized ink may break into an ink drop within a charge electrode and the charged ink drop may be deflected by a pair of deflection electrodes so as to travel toward a gutter. In response to the ink-placement signal a second ultrasonic transducer is de-energized when it has been energized in phase or in opposite phase with the first ultrasonic transducer when the second ultrasonic transducer has been de-energized so that the formation of each ink drop may occur outside of the charge electrode and the uncharged ink drop may travel to strike against a recording medium.

摘要： A first ink tank (17) is attached to a movable ink jet printing head (12) for supplying ink thereto. A second ink tank (28) which is larger than the first ink tank (17) is fixedly mounted at an end of a carriage (19) which supports the printing head (12). After the printing head (12) prints a line, a print end signal causes a sensor (33) to sense the amount of ink in the first ink tank (17). If the amount is low the printing head (12) is moved so that a connector (31) of the first ink tank (17) mates with a connector (29) of the second ink tank (28) and ink is urged to flow from the second ink tank (28) to fill up the first ink tank (17). The amount of ink in the first ink tank (17) is again sensed and if it is still low, indicating that the amount of ink in the second ink tank (28) is also low, an annunciator (41) is energized to urge the apparatus operator to fill the second ink tank (28) with ink.

摘要： In an ink jet recording apparatus including a carriage operative to move in scanning motion for printing characters and symbols on a printing surface and supporting thereon a single printing head having a plurality of ink jet nozzles or a plurality of printing heads each having a single ink jet nozzle, the printing surface is formed as a curved surface and the printing head or heads are constructed such that ink can be ejected radially with respect to the center of curvature of the curved printing surface. The vertical spacing between dots formed by ejected ink can be adjusted by moving the printing head or heads relative to the printing surface to thereby adjust the spacing between the printing surface and the printing head or heads, and the transverse spacing between the dots can be adjusted by adjusting the scanning speed of the printing head or heads or the ink ejecting timing.

摘要： A charging phase control device for an ink jet recording device wherein the ink droplets are positively or negatively charged in the recording mode. In the charging phase detection mode an ink droplet charging electrode is so energized that more than two successive ink droplets may be negatively or positively charged and one or more ink droplets which immediately follow said more than two successive, negatively or positively charged ink droplets may be uncharged or positively or negatively charged. The negatively or positively charged ink droplets repel each other and attract the uncharged or positively or negatively charged ink droplets so that they coalesce into large ink droplets. Therefore the distance between an ink head and an ink droplet detection means may be reduced, the ink jet recording or printing device may be made compact in size and light in weight; and ink droplet charging phase may be detected and controlled with a higher degree of accuracy.
