1. A feeder that includes a sprocket that feeds a tape accommodating multiple components and a motor that rotates the sprocket, and is detachably attached to a component mounting machine, the feeder comprising:
a sensor configured to detect a rotational position of the sprocket;
a storage section configured to store the rotational position of the sprocket detected by the sensor as an initial rotational position when the tape is set in the feeder with engagement to the sprocket and store a cumulative feeding amount of the tape fed by the rotation of the sprocket in a first direction, and
a control section configured to
control the motor such that the sprocket rotates in the first direction based on a feeding amount of the tape required for a supply when supplying the components to the component mounting machine,
determine if the feeder is detached from the component mounting machine,
when the feeder is detached from the component mounting machine,
compare the cumulative feeding amount of the tape to a predetermined amount, and
control the motor such that the sprocket rotates in a second direction to rewind the tape by the predetermined amount when the predetermined amount does not exceed the cumulative feeding amount, and control the motor such that the sprocket rotates in the second direction to rewind the tape by the cumulative feeding amount when the predetermined amount exceeds the cumulative feeding amount.
