Abstract
PURPOSE: To detect accurately a rotation direction by detecting the rotating of a reel turntable by outputs of two magneto-electric converting methods, by providing the rotatably-fitted reel turntable to a fixed substrate and a magnet part to the opposite surface side.
CONSTITUTION: Around axis 3 implanted in fixed substrate 2, reel turntable 1 is supported being pushed up through pressure spring 4 and its height direction is restrained by upper snap washer 5. At the lower part of reel turntable 1, ring-shaped magnet 6 provided with several magnetized poles is arranged with its magnetized surface opposing to substrate 2. Substrate 7 is provided with holes IC8 and IC9. The number of magnetized poles of magnet 6 is denoted by (n) [=2,4,6...] and they are provided to substrate 2 froming relative angles as shown by formula I. Further, holes IC8 and IC9 are fixed as shown in the Fig. and decision on clockwise and counterclockwise rotations of reel turntable 1 are made.
