摘要： A belt-conveyance control device includes a belt (30) that is supported by a drive roller (31) and a driven roller (32), a pulse motor (11) that drives the drive roller (31), and a first encoder (18) that is attached to the driven roller (32) to detect a displacement of the belt (30). The belt-conveyance control device controls a conveying speed of the belt (30). The belt-conveyance control device further includes a control unit that calculates a difference between the displacement detected by the first encoder (18) and a predetermined target value, calculates a pulse frequency of a driving pulse signal for driving the pulse motor (11) based on a feedback control based on the difference and a feed-forward control based on a reference driving pulse frequency, sets a control range of the feedback control to be equal to or smaller than a frequency of one rotation of the driven roller (32), and controls driving of the pulse motor (11) such that the belt (30) moves at a constant speed.
