Abstract:
1. A belt drive controller for controlling the driving of an endless belt so as to intermittently move said belt wrapped around at least two supporting rotating bodies including a driven supporting rotating body, which rotates accompanying movement of said belt, and a driving supporting rotating body which transmits a driving force to said belt, comprising: a detection unit that detects a first rotation angular displacement or a first rotation angular velocity of a first of the two supporting rotating bodies and a second rotation angular displacement or a second rotation angular velocity of a second of the two supporting rotating bodies, the first and second supporting rotating bodies having mutually different diameters among the two supporting rotating bodies; and a control unit that controls driving of the driving supporting rotating body based on rotation data detected by said detection unit so that the position of the belt in the direction of movement becomes a predetermined target position.
