PURPOSE:To remove the unstable state at reed switch operation for sure operation, by the step operation of the movement of a magnet through the use of a spring other than the rotation of the rotor. CONSTITUTION:When an input gear 12 is rotated by a pinion 11 delivered for the movement of a rotor, the gear 13 is rotated with the operation of a driving pin 121 via a notch hole 19, and a gear 20 pushes up the roller 141 latched to it against the operating force of the spring 14. The gear 13 is in step opration and tentatively stopped when the roller 141 is dropped between teeth of the gear 13. The rotor is rotated in this case and the driving pin 121 contacts the tip of the notch hole 19 of the gear 13, then the gear 13 starts to rotate by receiving the drive of the driving pin 121 to repeat the step operations. This step operation causes the magnet 151 in step operation as it is, and the reed switch 16 is in ON-OFF operation. |
