摘要:
An electronic device capable of increasing the braking torque applied to an electric power generator without causing a significant reduction in electric power generated by the electric power generator. The electronic device, which may be embodied in an electronically controlled mechanical clock, includes an electric power generator for converting mechanical energy transmitted from a spring via a wheel train to electrical energy, and a rotation controller for controlling the rotation period of the electric power generator. The rotation controller includes switches capable of connecting two terminals of the electric power generator in a closed-loop state, a chopping signal generator for generating two or more types of chopping signals which are different in duty ratio or frequency for use in a strong braking operation, and chopping signal selector that selects one of the chopping signals, wherein, in the strong braking operation, the selected chopping signal is applied to the switches so as to control the electric power generator in a chopping fashion. The strong braking operation is performed in one of two modes such that a higher priority is given to generation of electric power or the braking torque depending on the mode, thereby achieving an increase in the braking torque of the electric power generator without causing a significant reduction in the voltage generated by the electric power generator.

An electronic apparatus includes a power generator (20) as a power supply, a capacitor (30) for accumulating generated power, a logic circuit (170) driven by the power from the capacitor, and a power supply cut-off circuit (31). When the power generator starts operating,the power supply cut-off circuit (31) does not supply power to the logic circuit (170) until a voltage of the capacitor (30) reaches a preset voltage. When the voltage of the capacitor (3) becomes equal to or greater than the preset voltage, power is supplied from the capacitor to the logic circuit. Accordingly, a leakage current when power generation starts is prevented, and most of the generated power is accumulated in the capacitor. The capacitor, can rapidly accumulate electricity, and the time until activation of an electronic circuit driven by the capacitor is reduced.

A motion detection means 5 has a power generation detection circuit 51 for detecting the output voltage of a generating means 4, and a decision unit 52 for determining if the radio-controlled timepiece 1 is moving based on the output voltage from the power generation detection circuit 51. If when a standard time signal is to be received by means of a receiver 2 the not_moving detection signal indicating that the radio-controlled timepiece 1 is not moving is output from the motion detection means 5, the reception operation is executed and the time displayed on the time display means 3 is adjusted. By receiving the standard time signal when the radio-controlled timepiece 1 is not moving, accurate time information can be received and the reliability of standard time signal reception can be improved because the reception success rate is also improved.
