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： In a liquid discharge head having a movable member displaced by generation of a bubble, endurance of stepped portions of the movable member and of root portions of movable parts of the movable member is enhanced and flexure deformation of the movable member is prevented to enhance endurance of the member. A pressing member for covering stepped portions of a movable member and root portions of branched movable parts is provided within a flow path. A part of the pressing member is tapered and extends to a downstream side (toward a discharge port) to be spaced apart from the movable member, thereby forming a flexure regulating portion opposed to and spaced apart from an intermediate portion of the movable member. The pressing member and the flexure regulating portion suppress excessive deformation of the movable member.

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.

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 comprises a heating element which heats liquid in a liquid flow path to produce a bubble in the liquid, a discharge port through which liquid is discharged by pressure involved in bubble growth, the discharge port communicating with the lower part of the liquid flow path and being smaller in the area of a cross section at right angles to the direction of liquid introduction than the liquid flow path, a movable member which is provided like a cantilever in the liquid flow path, the free end of the member being positioned on the side of the discharge port, and a restrictor which substantially closes the upper part of the liquid flow path by being substantially brought into contact with the movable member when the movable member is displaced by the growth of the bubble, wherein a meniscus is in the discharge port when due to bubble breakage, the movable member moves from the normal position in such a direction that the liquid flow path is open widely and then returns to the normal position.

摘要： A method of manufacturing a liquid discharge head having a liquid flow path, a discharge energy generating device in the liquid flow path, a discharge port communicating with the liquid flow path, and a movable member facing the discharge energy generating device. The movable member is formed by a photolithographic technique, and a right-angled part and an acute-angled part of an edge of the movable member are removed so as to make a surface of the edge of the movable member curved. The curved surface of the movable member serves to reduce concentration of the stress on the movable member that occurs due to displacement of the movable member resulting from pressure of a bubble generated to discharge ink. Removal of the right-angled and acute-angled parts may be performed by soaking the movable member in an etching solution after formation of the movable member.

摘要： The invention is to vary the amount of the liquid discharged from a same discharge port, thereby realizing recording of multi gradation levels. After the discharge of a first liquid droplet 66a, a second liquid droplet 66b is discharged while the movable member 31 is still in a displaced state. In comparison with the first liquid droplet 66a, the second liquid droplet 66b has a larger discharge energy and a larger speed, because the moving energy of the movable member 31 and the energy consumed for the liquid flow opposite to the discharge port 18 are small. Thus the first and second droplets are united to form a united droplet 66d before landing on the recording medium 150. In this manner the amount of the discharged liquid can be varied.
