Abstract
A sheet feeding device has a correction value storage memory which stores correction values for the sheet feed error of the sheet feeding mechanism which appears in a specific cycle from a reference point to correct the sheet feed error, and a sensor which detects a particular point in the specific cycle. In accordance with the input from the sensor, the sheet feed amount is corrected by the correction value stored in the correction value storage memory. By correcting the feed error of each component of the sheet feeding mechanism, an exact and reliable sheet feed can be achieved without needing the increase of precision of the components of the sheet feeding mechanism.
