して好適である。FIG. 1 is a perspective view schematically showing an apparatus used in the present invention. In FIG. 1, a rotation detector 3 is attached to an out-end shaft 2 of a spinning machine chin roller or chin pulley 1 to detect the rotation speed A (rpm). The measurement location is as shown in the figure (the outer end is preferable as it has more space than the gear end).Also, as an example of a rotation detector, a non-contact type photoelectric switch or an electromagnetic magnet sensor is lightweight, It is suitable for being easy to use because of its small size.
