Abstract:
1. A reading apparatus comprising: an optical image forming unit that forms an optical image on a recording medium by irradiating, with light, the recording medium on which an image is formed and which is transported in a slow scan direction; a reading unit that reads a position in a fast scan direction of the image formed on the recording medium transported in the slow scan direction and a position in the fast scan direction of the optical image, by using a minification optical system; and a correction unit that corrects a magnification variation in the fast scan direction of the image read by the reading unit, by using the position in the fast scan direction of the optical image read by the reading unit, wherein the correction unit further corrects the magnification variation in the fast scan direction of the image read by the reading unit by using an end position of the recording medium read by the reading unit, and wherein the magnification variation in the fast scan direction of the captured image is due to the floating of the paper sheet.
