Patent ID: 7213900

Claim:
An image recording apparatus comprising: a recording head section which achieves an expanded recording width by recording a plurality of interconnected images; a mark identification section which identifies whether or not an identification mark is present on a recording sheet in the image recording apparatus, and which identifies, based on identification of the identification mark: (i) whether or not a pattern for measurement is provided on the recording sheet, and (ii) a type of the pattern for measurement if it is determined that the pattern for measurement is provided on the recording sheet; a measurement image generation section which produces image data for measurement; an image data selection section which selects the image data for measurement to be recorded on the recording sheet in accordance with an identification result of the mark identification section, such that the image data for measurement is recorded on the pattern for measurement on the recording sheet, when the pattern for measurement is provided on the recording sheet; a peak interval calculation section which calculates a shift amount based on a positional relationship between the image data for measurement recorded on the recording sheet and the pattern for measurement provided on the recording sheet; and a printing timing correction amount calculation section which corrects a position of a recorded image formed by the recording head section based on the shift amount calculated by the peak interval calculation section.
