Patent ID: 7095679

Claim:
An electronic timepiece with a coil comprising: a signal input unit for inputting a signal in response to an external operation; a mode setting unit for switching, in response to the signal, an operation mode of the electronic timepiece between a data receive mode and a normal operation mode; a synchronization signal generating unit for generating, when the operation mode is in the data receive mode, an internal synchronization signal that is synchronized to an external synchronization signal transmitted from an external transmitting device; a received data recovery unit for recovering, when the operation mode is in the data receive mode, received data on the basis of the internal synchronization signal and a data voltage signal induced across the coil by a transmitted data signal from the external transmitting device, and for outputting the received data; and an operation control unit for placing the received data recovery unit in an operation enabled state only during a prescribed time period while the electronic timepiece is in the data receive mode.
