摘要： A printer is provided with an ink jet head and a controller. The ink jet head prints on a print medium by discharging ink. The ink jet head comprises a plurality of units. Each unit comprises a nozzle for discharging ink, a pressure chamber communicating with the nozzle, and a piezoelectric element facing the pressure chamber. The piezoelectric elements form at least two element lines. Each element line is formed by at least two piezoelectric elements aligned in a first direction. Each element line is aligned in a sec direction which is different from the first direction. The controller controls the ink jet head to print on the print medium by changing voltage applied to each piezoelectric element of the ink jet head. The controller controls timings at which the controller changes voltage applied to each piezoelectric element by the element line. It is preferred that a timing at which the controller changes voltage applied to one of the two adjacent element lines is different from a timing at which the controller changes voltage applied to the other of the two adjacent element lines.

摘要： A liquid ejection head includes a passage unit and an actuator. A nozzle for ejecting liquid and a common liquid chamber are formed in the passage unit. An individual liquid passage formed in the passage unit includes a first passage a pressure chamber, a second passage, and a restricted passage. The first passage communicates between the nozzle and the pressure chamber. The second passage communicates between the pressure chamber and the restricted passage. The restricted passage is smaller than the second passage in the sectional area perpendicular to the flow of the liquid. The actuator can selectively take a first state in which the volume of the pressure chamber is V1 and a second state in which the volume of the pressure chamber is V2 larger than V1. The actuator changes from the first state into the second state and then returns to the first state to eject the liquid from the nozzle. The individual liquid passage is designed so that Tc1 and Tc2 defined by predetermined expressions showing characteristics of the individual liquid passage satisfy a condition that Tc1/Tc2 is substantially not less than 4.7 and not more than 5.5.

摘要： The control electrode unit including an insulative layer, a reference electrode on one surface of the insulative layer and at least one segment control electrode on an opposite surface of the insulative layer to which an image signal is applied. The control electrode unit has at least one row of apertures which pass through the segment control electrode, the insulative layer and the reference electrode, so that the charged particles pass through the apertures. The image recording apparatus includes a plurality of carrying units for carrying charged particles of different colors, and a moving unit for moving one of the carrying unit to the position disposed confronting the recording medium through the position confronting the medium through the control electrode unit. One of the carrying units is disposed at a position confronting the medium through the control electrode unit so that the charged particles carried by the carrying unit are carried toward the recording medium through the apertures. Thus, the image recording apparatus has a single control electrode unit, even though the image recording apparatus has the plurality of carrying units. Two levels of vibration are applied to the control electrode unit. A first level, in the recording mode, prevents particles from adhering to the electrode. A second level, in a non-recording mode is at a higher level to remove particles from the electrode. In an alternative embodiment, the plurality of carrying units are fixed in position and each has a corresponding control electrode. Image formation occurs by controlling movement of the recording medium relative to the carrying units.
