A feeder includes a sprocket that feeds a tape accommodating multiple components; a motor that rotates the sprocket; a storage section to store the rotational position of the sprocket detected by a sensor as an initial rotational position when the tape is set in the feeder and store a cumulative feeding amount of the tape fed by the rotation of the sprocket; and a control section to control the motor such that the sprocket rotates in a forward direction based on a feeding amount of the tape required for a supply when supplying the components to the component mounting machine, and control the motor such that the sprocket does not rotate in a reverse direction in excess of the initial rotational position based on the initial rotational position and the cumulative feeding amount when rewinding the tape.
