PURPOSE:To make it possible to be used in a region where ferromagnetic fields exist, by sensing the direction of a moving body by an centrifugal force sensing device, a pulse generator as a clock signal generator, a speed sensing device, and a detecting device. CONSTITUTION:The speed sensing device 10 supplies the speed signal of moving body to the detecting device 13. The pulse generator 11 as the clock signal generator supplies a time signal to the detecting device 13. The centrifugal force sensing device 12 supplies the centrifugal force signal of the moving body to the sensing device 13. An angle signal is outputted from the detecting device 13 to which each signal is supplied, and the advancing direction of the moving body is displayed by a display 14. |
