Abstract
PURPOSE: To simplify the structure of a vibration detection unit by detecting the vibration state dependently upon light receiving change of a photo detecting material.
CONSTITUTION: Light emitting element 9 and photodetector 10 are inserted from the lower part and are fixed to a pair of inclined holes 5 and 6 which pass through pedestal 2 toward the center of fixed hole 3. When ball 4 exists in the home position, the light radiated from light emitting element 9 is reflected on the lower part of ball 4 and is received by photo detector 10, and photo detector 10 indicates, for example, the low resistance value as a signal of non-vibration. When vibration occurs to remove ball 4 from the home position, the light radiated from light emitting element 9 cannot be reflected and is not received by photodetector 10. Under this state, photodetector 10 indicates the high resistance value as a signal of vibration- state. Then, after vibration stops, ball 4 is put on the home position by magnet 13, etc.
