Abstract

PURPOSE:To increase a use while improving the accuracy of the detection of speed by a mechanism wherein a rotor is formed by means of die casting by a nonmagnetic material while an outer tooth gear consisting of a magnetic material is fixed to the one end, and an inner tooth gear for detecting speed is opposed to the outer tooth gear. CONSTITUTION:A rotor 10 is formed by die casting consisting of a non-magnetic material, such as zinc die casting, etc. A drive magnet 33 is fixed onto a lower end surface of the rotor 10, and faced to a drive coil 34 at the fixing side. A speed detecting portion is formed in such a manner that the first gear member 40, which consists of a magnetic material and has outer tooth gear 36, is fastened onto an upper end surface of the rotor 10 while the second gear member 41 with an inner tooth gear 44 is made up at the fixing side and opposed to the member 40. The first capstan 7a is directly driven by means of the rotor 10, and capstans can be driven in a dual shape by spanning a belt 9 between a fly-wheel 11 of the second capstan 7b and the rotor 10.
