ABSTRACT:
A belt moving device of the present invention includes a drive shaft for moving the belt and a drive transfer line for transferring the output torque of a motor to the drive shaft. A marker sensor senses a marker positioned on the belt to thereby determine the position of the belt in the direction of movement. A rotation condition sensor senses the rotation condition of the drive shaft. A first correction information generating circuit generates, based on the output of the marker sensor, correction information for correcting the position of the belt. A second correction information generating circuit generates, based on the output of the rotation condition sensor, correction information for correcting the rotation condition of the drive shaft. A controller controls the movement of the motor in accordance with the correction information output from the first and second correction information generating circuits.
