Abstract:
1. An image recording apparatus comprising: a recording drum rotatable with a recording medium mounted peripherally thereof; a recording head for recording an image on said recording medium mounted on said recording drum by emitting light beams according to image signals to said recording medium; a rotation angle detecting device for detecting a rotation angle of said recording drum; a sensor device for detecting said recording medium mounted on said recording drum; a detection range setting device for setting a range of detection of said recording medium by said sensor device with respect to said rotation angle of said recording drum, wherein at least one of information on said recording medium and a recording resolution of the image recorded by said recording head is used to shift and set said range of detection in the rotation direction of said recording drum in order to correspond to the recording medium and/or recording resolution to be used; and a determining device for determining a position of an edge of the recording medium mounted on said recording drum, by fetching signals from said sensor device based on the rotation angle of said recording drum detected by said rotation angle detecting device and the range of detection set by said detection range setting device.
