摘要： Liquid is discharged at a high frequency in a consecutive manner with a liquid discharge head having a movable member. A bubble formed for discharge a first discharged droplet grows large into a discharge port side by the movable substantially closing a common liquid chamber side in a bubble forming procedure, and disappears fast at the common liquid chamber side by the movable member releasing the common liquid chamber side of a flow path in a bubble disappearance procedure, and reaches a state to remain at the discharge port side of a heat-generating body. Under this state, since the bubble disappears at the common liquid chamber side, a constant liquid is refilled to reach the discharge port side, and the bubble does not yet completely disappear, a meniscus is disposed comparatively closer to a liquid discharge face. Under the circumstances, if discharge of a second discharged droplet is arranged to start from this state, the liquid can be discharged well at a short interval in a consecutive manner.

摘要： A liquid discharge head is provided having a heating member for generating thermal energy to create a bubble in liquid, a discharge port adapted to discharge the liquid, and a liquid flow path communicated with the discharge port having a bubble generating area for enabling the liquid to create the bubble. A movable member is arranged in the bubble generating area to be displaced along with the development of the bubble. A regulating portion regulates the displacement of the movable member within a desired range, and by means of energy at the time of bubble creation, the liquid being discharged from the discharge port. The regulating portion is arranged to face the bubble generating area in the liquid flow path. A support member is directly connected to the movable member. The bubble development causes the movable member and the regulating portion to be in contact forming an essentially closed space with the exception of the discharge port.

摘要： A liquid discharge head comprises heating members for generating thermal energy to create bubbles in liquid, discharge ports forming the portions to discharge the liquid, liquid flow paths communicated with the discharge ports, at the same time, having bubble generation areas for enabling liquid to create bubbles, movable members arranged in the bubble generation areas to be displaced along with the development of the bubbles, and regulating members to regulate the displacement of each of the movable members within a desired range, and with energy at the time of bubble creation, the liquid being discharged from the discharge ports. For this liquid discharge head, each of the liquid flow paths holds bubbles at the time of bubbling, at the same time, being provided with gaps arranged on the sides of the movable member to allow the liquid on the upstream thereof to flow into the bubble generation area at the time of bubble disappearing. With the structure thus arranged, the meniscus is drawn into the liquid flow path quickly immediately after the bubble disappearing of bubble begins, and then, with a strong force of the meniscus, the trailing portion of the liquid column connected with the discharged droplet is cut off outside the discharge port, hence making the number of satellites smaller for the enhancement of the quality of prints.

摘要： A liquid discharge head includes plural heat generating members, each linearly communicating with a discharge port, a liquid flow path communicating with each discharge port and having a bubble generating area in which a movable member is provided, a limiting portion opposed to the bubble generating area in the liquid flow path for limiting displacement of the movable member, and a circuit for receiving data of a predetermined number of bits for each heat generating member and generating drive pulses for each heat generating member based on the respective input data. Substantial contact between the displaced movable member and the limiting portion renders a portion of the liquid flow path including the bubble generating area a substantially closed space except for the discharge port. The number of drive pulses generated from the input data is larger than the predetermined number of bits for at least one set of the data.

摘要： A boundary nozzle which is contained in a block that has not been driven and is situated at the boundary with a driving block that is driven prior to the block containing the boundary nozzle contains a second stopper which has a length in a liquid flow direction longer than that of a first stopper contained in a driving nozzle in the driving block that is driven prior. A near-boundary nozzle adjacent to the boundary nozzle has a third stopper which has a length in a liquid flow direction longer than that of the first stopper but shorter than the second stopper. Thus, recording irregularities owing to meniscus regression are suppressed.
