Patent ID: 7422298

Claim:
An inkjet recording apparatus comprising: a recording head having a nozzle row aligned with a plurality of nozzles for ejecting ink; a carrying mechanism configured to carry a record medium by a multiple of an arbitrary natural number of a unit carrying amount in a direction in parallel with the nozzle row; a logical carry amount obtaining unit that obtains a logical carry amount based on a recording resolution along the direction in parallel with the nozzle row and a number of nozzles that are used for recording in the nozzle row and is indicated as a multiple of the unit carrying amount; a carry controlling unit that controls the carrying mechanism such that the record medium is carried by any of a plurality of quasi logical carry amounts including a natural number larger than the logical carry amount, and a natural number smaller than the logical carry amount; and a recording head controlling unit that controls the recording head such that the record medium is recorded at each time of carrying the record medium by the carrying mechanism that is controlled by the carry controlling unit; wherein the carry controlling unit determines a carry amount of the record medium by the carrying mechanism from the plurality of quasi logical carry amounts such that a difference between a carry amount when the record medium is assumed to be carried by the logical carry amount and an actual carry amount of the record medium does not exceed a predetermined value.
