Abstract
An inkjet recording apparatus including: a recording head; a recording medium moving section; a position information detecting section synchronized with a movement of the recording medium moving section; a mark recording section for recording a mark on the recording medium; a mark detecting section for detecting the mark recorded; an analog-to-digital conversion section for converting an output signal; and a control section for obtaining a reference mark position of the mark based on a signal outputted from the mark detecting section and the position information detected, and for determining the amount of recording medium movement on the basis of reference detection position of the mark; wherein analog-to-digital conversion is applied to the output signal from the mark detecting section to get a sampling data, in exact timing with an output of position information, and the control section calculates the reference detection position from the sampling data.
