A feeding device including: (a) a feed mechanism including a motor driven with supply of a power thereto, and a feeder operated by the motor for feeding an object; (b) a power supply controller for supplying the power to the motor until an actual operating position of the feeder coincides with a power-supply-stop operating position located before a target operating position of the feeder, and to stop the supply of the power to the motor when the actual operating position coincides with the power-supply-stop operating position, for causing the actual operating position to eventually coincide with the target operating position owing to an inertia of the feed mechanism; and (c) a power-supply-stop operating-position determiner for determining the power-supply-stop operating position, for reducing a positioning error of the object in presence of a torque fluctuation of the feed mechanism, based on the target operating position and a cyclic variation of an operating velocity of the feeder that is caused by the torque fluctuation.
