Abstract: A printing head has a plurality of heater boards, each of which includes a shift register to which printing data and selection data for selecting preheating pulse signals are applied as inputs, a latch circuit for latching the printing data, a selection-data latch circuit for latching the selection data, a selection circuit for selecting any one of a plurality of preheating pulse signals inputted in accordance with the latched selection data, and a plurality of heating resistors driven by the printing data or preheating pulse signals. Correction data, obtained by a head correcting apparatus, for performing printing at an average density by correcting the characteristics of each heater board is stored in a memory of the printing head. A printing apparatus decides the selection data in accordance with the correction data and sets the selection data in the selection-data latch circuit.

Abstract: The present invention provides a liquid discharging head comprising a discharge port for discharging liquid, a bubble generating area (11) for generating a bubble in the liquid, a movable member (31) disposed in a confronting relation to the bubble generating area and displaceable between a first position and a second position more spaced apart from the bubble generating area than the first position, and side members integrally formed with at least parts of the movable member on its both sides and shiftable together with the movable member and adapted to cover sides of a bubble generated, and wherein the movable member is shifted from the first position to the second position by pressure due to generation of the bubble in the bubble generating area, and the bubble is more expanded downstream than upstream of a direction toward the discharge port by the displacement of the movable member. The present invention further provides a head cartridge having such a liquid discharging head and a liquid discharging apparatus having such a liquid discharging head.
