The vibration detector is supported in a case so as to be able to swing freely, and furthermore, a contact portion is provided on the amplitude trajectory of the vibration detector, and the vibration detector has a number of slits formed at predetermined intervals on the concentric circle of the pivot point. A photo interrupter is constructed by arranging a light emitting element and a light receiving element facing each other with the slit sandwiched between them on the sides of the vibration detecting body. The structure is such that when the slit crosses the photointerrupter, its displacement produces a pulse output from the light receiving element.
