Abstract
PURPOSE:To improve the reliability of an electronic timepiece with a charging function by letting a user know whether charging is in process or not, by displaying the data of a charging detection circuit on a display device. CONSTITUTION:An oscillator 21 such as a quartz oscillator, a charging detecting circuit 22 for detecting charging being in process, an electronic circuit 23 including an oscillating circuit, a frequency dividing circuit, a processing circuit, a display circuit, etc., and a display device 24 are provided. The charging detecting circuit 22 judges whether charging is being carried out or not, and the result is displayed on the display device 24 through the electric circuit 23. The charging detecting circuit 22 connects a terminal 31 to the plus-side power sources of a charger and a battery. A terminal 32 is connected to the minus-side power source of the charger, and a terminal 33 is connected to the minus-side power source of the battery. A comparator 34 performs comparison betweent the potentials obtained by dividing potentials at the terminals 32 and 33 through resistances. Namely, when the voltage of the charger is higher than a battery voltage, namely, when the potential of the V1 is lower than that of the VsS, the comparator 34 generates a high-level// output.
