PURPOSE:To let receiving be surely performed with a coil as an antenna by connecting the coil of a step motor to receiving part and preventing driving pulses from being sent to the coil at the receiving of signal thereby letting error component be automatically corrected after receiving the signal. CONSTITUTION:Both ends of the coil 10 of a motor part 2 are connected to the motor driving output end of the watch part 1 via gate 5 and the signal input end of receiving part 3 via gate 6. At the ordinary time, the power sources of the receiving part 3 and signal processing part 4 are held off, the gate 5 conducts, the gate 6 is cut off and a step motor 2 is operating. When a switch 9 is operated for the purpose of receiving, the power sources of the receiving part 3 and signal processing part 4 turn ON. Then the gate 5 is turned OFF and the gate 6 ON, and the driving pulses from the watch part 1 are no longer sent to the coil 10, thus the transmission electromagnetic wave from the outside induced in the coil 10 is sent from the receiving part 3 to the signal proceccing part 4, whereby signal processing is accomplished. |
