PROBLEM TO BE SOLVED: To provide a belt drive controller capable of controlling each belt stopping position with high accuracy during intermittent movement of a belt. SOLUTION: This belt drive controller controls driving of a belt to intermittently move a belt wrapped around a plurality of supporting rollers including a driven roller 4 and a drive roller 3. This controller detects a rotation angular displacement or a rotation angular velocity of two supporting rollers having mutually different diameters, and controls driving of the drive roller based on the detected rotation data so that the position of the belt in the direction of movement becomes a predetermined target position.
