Abstract:
1. An image recording apparatus for recording an image on a recording medium based on information from a higher-level device, the image recording apparatus comprising: a paper feeding mechanism for feeding the recording medium, the paper feeding mechanism including a medium fence for aligning the recording medium by pressing against both side ends of the recording medium, the side ends being parallel to a conveyance direction of the recording medium, so that a center of the recording medium in a direction orthogonal to the conveyance direction coincides with a midpoint of a conveyance path in the direction orthogonal to the conveyance direction; a recording medium side end detecting unit having a detection length that is approximately one half of a maximum width of a recording medium that is conveyable in the conveyance path, the recording medium side end detecting unit detecting a distance from the midpoint of the conveyance path in the direction orthogonal to the conveyance direction to a position of one of the side ends of the recording medium; and an image recording range setting unit which estimates a width of the recording medium to be twice the distance detected by the recording medium side end detecting unit, which sets a recording range on which image recording is to be performed, based on the estimated width, and which executes an image recording process on the recording range.
