发明名称 Tape tension control apparatus
摘要 A tape tension control apparatus for controlling tape tension by supplying a current to a reel motor for driving a reel in accordance with a diameter of a tape roll includes arotational speed detector for detecting the rotational speed of the tape roll a;rotational speed comparator for comparing a rotational speed detected by the rotational speed detector and a standard rotational speed corresponding to the diameter of the tape roll; and acurrent corrector for correcting the value of the current supplied to the reel motor in accordance with a comparison result from the rotational speed comparator in such a manner that the speed of rotation of the reel motor becomes equal to the standard rotational speed.
