Claims

[Claims for Utility Model Registration] A rotating main shaft, a slave shaft driven by the main shaft, a feed roller that rotates together with the slave shaft and transports a tape with marks marked at regular intervals on one side, a mark sensor that sends out a mark detection signal when the mark on the transported tape passes; a mark advance detection means that sends out a mark advance limit signal every time the main shaft rotates; a mark delay detection means for transmitting a delay limit signal for the mark after a predetermined time has elapsed since the mark detection; a speed governor interposed between the main shaft and the slave shaft to adjust the rotational speed of the slave shaft; and mark detection. When the signal transmission timing advances and matches the limit signal transmission timing, the rotation speed of the slave shaft is decelerated, and when the mark detection signal transmission timing delays and coincides with the limit signal transmission timing, the rotation speed of the slave shaft is reduced. and control means for controlling the speed governor to increase the speed of the feed roller.
