PURPOSE:To simplify the delivery path of force of train wheel including the phase detector, by providing two sets of phase detectors to the watch of analog display and directly fitting the phase detection plate to the pointer shaft. CONSTITUTION:The 1st phase detection plate 12 incorporated with the center minute pinion 11 turns one per one hour, and the phase detection gear 19 latched with the hour wheel 15 turns once per 12hr, and the second phase detection plate 20 incorporated with the phase detection gear 19 turns once per 12hr. Further, the phase detection plate is slid with the contact springs 33-39 and 53-51, the signal obtained with the contact springs is input to the code counter circuit and the phase of the pointer in analog display is grasped as digital quantity with signal processing. |
