Abstract
A magnetic ink character reading method includes conveying paper by a stepping motor, detecting magnetic ink characters on the paper and generating magnetic detection signals by a magnetic detection unit, generating magnetic noise data by accumulating magnetic detection signals before the paper passes the magnetic detection unit, and removing the magnetic noise by subtracting the magnetic noise data from the magnetic detection signals. The generated magnetic noise can be a function of a control period of the transportation mechanism and a control period of a photodetector.
