An inkjet recording apparatus conducts image recording by ejecting ink and a reactive liquid that reacts with the ink onto a recording medium conveyed by an endless conveyor component. The inkjet recording apparatus includes: a dummy ejection controller that dummy-ejects one of the ink and the reactive liquid onto a first position on the endless conveyor component and dummy-ejects the other of the reactive liquid and the ink onto a second position on the endless conveyor component where the one of the ink and the reactive liquid is not adherent; and a cleaning device that cleans the ink and the reactive liquid on the endless conveyor component.

A recording head includes: liquid discharge ports that discharge liquid and are arranged at a pitch corresponding to a resolution, wherein said liquid including an ink; plural drive elements that cause the liquid to be discharged from the liquid discharge ports in correspondence to the liquid discharge ports and are arranged at a pitch corresponding to the resolution; and plural drivers having voltage buffer regions for buffering effects resulting from a high voltage, said drivers being serially connected in a one-to-one ratio to, and unitized with, the drive elements, and being arranged at a pitch enlarged by at least the voltage buffer region portions with respect to the pitch of the drive elements, and driving the drive elements.

Recording head and image recording device

An ink-jet recorder is disclosed which has an arrangement of a plurality of heat-generating elements, drivers for driving the heat-generating elements, and a drive circuit for controlling the drivers according to image data, wherein the drive circuit includes; a split-block drive circuit that divides the plurality of heat-generating elements into a plurality of blocks, and drives the heat-generating elements on a block-by-block basis in a time-sharing manner, and a data retaining circuit for retaining print data; and the split-block drive circuit that; drives each of the blocks of the heat-generating elements at printing operations, using a pre-pulse during which ink is not squirted and a main pulse during which ink is squirted; and drives another group of heat-generating elements differing from the currently-driven group of heat-generating elements, during intervals between the pre-pulse and the main pulse.

A fuzzy logic circuit for operating a fuzzy logic with 'fuzziness' taken into account has an operation section memory unit in which the result of operation to be outputted in response to an input is stored in an address specified by the input, the result of operation being rewritable, whereby the change in the contents of a fuzzy logic operation to be performed can be handled merely by rewriting the contents of the operation section memory unit.
