    Abstract: A liquid ejecting method for ejecting liquid by generation of a bubble includes preparing a head comprising an ejection outlet for ejecting the liquid, a bubble generation region for generating the bubble in the liquid, a movable member disposed faced to the bubble generation region and displaceable between a first position and a second position further from the bubble generation region than the first position; displacing the movable member from the first position to the second position by pressure produced by the generation of the bubble in the bubble generating portion to permit expansion of the bubble more in a downstream side closer to the ejection outlet than in an upstream side; and wherein the displacing step including: first bubble generation step of displacing a free end side of the movable member by pressure produced by generation of a bubble in the bubble generating region; and second bubble generation step of generating at least one other bubble in the bubble generating region to eject the liquid through the ejection outlet.

    Abstract: Disclosed herein is a liquid discharging method, comprising using a liquid-discharge head equipped with a discharge opening from which a liquid is discharged, a first region to which a first liquid is supplied, a bubble-generating region containing a second liquid and generating bubbles in the second liquid, and a movable member which is displaceable between a first position opposite to the bubble-generating region and a second position within the first region and apart from the bubble-generating region and has a support part more upstream than its free end, in which the movable member is displaced from the first position toward the second position with the generation of a bubble in the bubble-generating region, and the bubble is guided to the discharge opening by the movable member, wherein the first liquid and the second liquid have no compatibility with each other.

    Abstract: A print head of this invention has a plurality of heater boards, and each heater board has a plurality of heating resistors, driver circuits corresponding to the heating resistors, one shift register for inputting serial data, a data latch circuit for latching print data input from the shift register, a pre-heat data latch circuit for latching selection data of selecting one or several of pre-heat signals input from the shift register, and a pre-heat selection circuit for selecting one or a plurality of pre-heat signals in accordance with the selection data latched in the pre-heat data latch circuit. In a print operation, one or several of the plurality of input pre-heat signals are selected to pre-heat the heating resistors, and when a main heat signal is input thereafter, the heating resistors are driven in accordance with the print data latched by the data latch circuit, thus performing the print operation.
