More Information
Summary:A belt driving device includes an adjustment roller to stretch and rotate an endless belt; an inclination adjuster including a cam to adjust inclination of the roller to control deviation of the belt; a belt position detector to detect a belt position in a direction orthogonal to a movement direction of the belt; a stepping motor to rotate the cam; and a control output adjuster to adjust a control output to be supplied to the motor based on the belt position. When obtaining a rotation angle less than one step of the motor, the control output adjuster supplies the control output to the motor for a time corresponding to the rotation angle less than the one step out of a supply time of the control output for obtaining a rotation angle of the one step, and stops supplying the control output for a remaining time out of the supply time.
