Abstract
An Electronic clock having an electric power generating element which is operable even in a state where the voltage of the electric power generating element is low. The electronic clock includes an electric power generating element, a low-voltage oscillating circuit which can oscillate even with a low voltage with the electromotive force developed by the electric power generating element as a power supply, an electronic clock movement having signal generating means, a voltage detecting circuit that detects an output voltage of a charging circuit, a selecting circuit that selects any one of the output signal of the low-voltage oscillating circuit and the output signal of the signal generating means on the basis of the voltage detection result to output it, and a step-up circuit that inputs an output signal of the selecting circuit and a voltage from the electric power generating element for stepping it up to output a stepped-up voltage to the charging circuit.
