Abstract:
1. An exposure device for exposing a predetermined imaging region at a recording medium with a light beam, which has beens modulated in accordance with image data, for forming an image corresponding to the image data at the imaging region, the exposure device comprising: an exposure stage on which the recording medium is placed; a reading section which, at a reading position facing the recording medium on the exposure stage, reads alignment marks from the recording medium, the alignment marks having been provided to correspond to the imaging region; an information processing section which determines a position of the imaging region at the recording medium on the basis of read information from the reading section, and performs position conversion processing on the image data in accordance with the position of the imaging region; and an exposure section disposed at an upstream side, along a scanning direction, of the reading section, which exposure section exposes, at an exposure position facing the recording medium on the exposure stage, the imaging region of the recording medium with the light beam, which has been modulated on the basis of image data from the information processing section, for forming the image at the imaging region, wherein the reading section and the exposure section are structured to be relatively movable in the scanning direction with respect to the recording medium on the exposure stage, by at least one of before commencement of exposure of the imaging region by the exposure section, the reading section reads the alignment marks that correspond to at least one of and the information processing section performs the position conversion processing on the image data on the basis of read information of these alignment marks.
