Claims

[Scope of utility model registration request]

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 on one side at regular intervals, and marks on the tape being transported. A mark sensor that sends out a mark detection signal when passing, a mark arrival abnormality detection means that sends out a delay signal or an advance signal of the mark every time the main shaft rotates, and is interposed between the main shaft and the slave shaft, A governor that adjusts to either a first gear that increases or decelerates the rotational speed of the slave shaft, or a second gear that increases or decelerates the rotational speed of the slave shaft from the first gear. The device increases or decelerates the rotational speed of the vertical axis by the first gear stage when the sending timing of the mark detection signal coincides with the sending timing of the delayed signal or the advanced signal, and generates the mark detection signal and the delayed signal or the advanced signal. a control means for controlling the speed governor so that the rotation speed of the slave shaft is increased or decelerated by a second gear stage when the feed timings of the feed rollers continue to match.
