<p>PURPOSE:To obtain an FG function with high accuracy by providing a fixed slit plate, a rotating slip plate, a light emitting/receiving element arranged so as to face the plates, and a magnet, which magnetically sandwiches the rotating slit plate between a capstan and an integrally rotating rotor. CONSTITUTION:A projecting part 26 provided at the external circumference of a C-shaped spring ring 25 penetrates into a notch hole 27 provided at a capstan bearing housing 2, and the notch hole performs positioning and detent. A suction magnet 15 is provided on the upper part of a rotor 8, and a rotating slit plate 17 is sandwiched at the section of the rotor 8. A protruding part 28 provided at the inner surface of the capstan bearing housing 2 supports the slit part of a fixed slit plate 16. The attraction magnet 15 holds the rotating slit plate 17, generates force to energize the rotor 8, consequently a capstan 1, upward with the aid of the attraction force at the section of an attraction plate 14, and receives thrust force with a thrust receiver 5. Thus, the titled capstan device with a highly-accurate FG can be obtained.</p> |
