Abstract
PURPOSE:To reduce the consumption of a battery and to prolong the life of the battery by arranging a magnetism sensing element and a permanent magnet opposite a rotary shaft and a fixed part, converting magnetism induced at the magnetism sensing element into an electric signal, an detecting a rotating speed. CONSTITUTION:When the rotary shaft 1 makes one turn, a vigant wire 8 cuts off the magnetic fields of permanent magnets 9 and 10 and the magnetic field of the vigant wire 8 is inverted in direction; and a voltage pulse which changes in rotating direction on each turn is outputted to a one-time detection coil 11 and a waveform processing circuit 12 outputs a signal indicating the rotating speed of the rotary shaft 1 to a signal processing circuit 7 through an up/down counter circuit 13. In this constitution, the rotating speed of the rotary shaft 1 when a generated power source is turned off is detected by the vigant wire 8 to reduce the consumption of the battery, thereby prolonging the life of the battery.
