Abstract

PURPOSE:To prevent a voltage drop across a battery by preventing electromechanical transducers from being driven simultaneously by putting signals, driving those electromechanical transducers, out of phase. CONSTITUTION:The rotation of the 1st electromechanical transducer A9 is transmitted to the 1st wheel train A10 to rotate a second hand 11 which functions as the 1st pointer. The 2nd electromecanical transducer B12 provides normal rotation and reverse rotation, which are transmitted to the 2nd wheel train B13 to rotate a minute hand 14 and a hour hand 15 which function as the 2nd pointers. The 1st electromechanical transducer A9 and 2nd electromechanical transducer B12 are driven once in every 20sec at the same timing, but they have an about 7.8ms phase difference theta1, so that their driving currents never flow at the same time.
