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： The invention intends to maintain a constant ink discharge amount among the recording heads, even in case a total pulse width of pulse voltages applied to heat generating resistors. For this purpose, a rank table is prepared in such a manner, even in a situation where a total pulse width of the pulses applied to the heat generating resistor is 3 μs or less whereby the ink discharge amount decreases with a decrease in the total pulse width, that a maximum reached temperature on the surface of the heat generating resistors at the application of a preheat pulse becomes higher with a decrease in the resistance of a rank resistor, and a pulse width P1 on the rank table is made longer thereby compensating a decrease in the ink discharge amount with a decrease in the total pulse width and maintaining a constant ink discharge amount.
摘要翻译：本发明即使在施加到发热电阻器上的脉冲电压的总脉冲宽度的情况下也能够在记录头之间保持恒定的墨水排出量。为此，即使在施加到发热电阻器的脉冲的总脉冲宽度为3微米以下的情况下，也以这样的方式准备了排列表，从而随着总脉冲的减少，墨水排出量减少宽度，在施加预热脉冲时发热电阻器表面上的最大达到温度随着等级电阻器的电阻的降低而增加，并且脉冲宽度P <1> 排列表越长，从而通过总脉冲宽度的降低来补偿墨水排出量的减少并保持墨水排出量的恒定。

摘要： In a liquid discharge detection method and apparatus which detect a liquid discharged from a liquid discharge head, an electrode is placed at a position where the liquid discharged from the liquid discharge head comes into contact with the electrode while being in contact with the head. When a liquid is discharged, and the head is connected to the electrode through the liquid, the circuit becomes a closed circuit. A voltage generated between the two ends of a resistor is obtained from a current flowing in the closed circuit. When this voltage becomes equal to or higher than a predetermined voltage, liquid discharge can be detected.

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.
