PURPOSE:To continuously indicate the fact that the operation hour is elapsed by stopping the indication by which the computed operation hour of the timer is indicated by rotation of the indicator after a specified operation hour has elapsed. CONSTITUTION:Friction mechanisms 24, 22A, and 23 are provided between gear mechanisms 4, 9, 11, 13, and 21 on the driven side having the indicators 7a1, 7a2, and 7a3 and gear mechanisms 23 and 25 on the driving side. When the indicating plate 7 rotates until a knob 7b of the indicating plate 7 is contacted with a pin 8, the rotation of the indicating plate 7 is stopped and does not rotate, even though a driving motor of the timer is continuously rotated, and the fact that the operation hours has elapsed is notified. |
