Abstract
Disclosed is an electronic timepiece radio having an electronic timepiece circuit, a circuit for detecting a time signal and correcting the time indication of the electronic timepiece by the detected time signal. And a preset system receiving circuit can receive more than two preset broadcasting stations. And a receiving frequency in the receiving circuit can be automatically set at the frequency of a specified preset station little before a time correction by a time signal is carried out at the receiving of the time signal whereby time indication is automatically corrected every day.
Claims5
An electronic timepiece radio comprising:
- an electronic timepiece circuit including a standard signal oscillator, a time counting circuit and means for displaying a time determined by the count of the time counting circuit;
- a radio receiver circuit including a tuning circuit, station selecting means for selecting different broadcast station frequencies, detecting means for detecting received signals applied from said tuning circuit, and means for producing audible frequency signals in response to the output of said detecting means;
- a correction time detector connected to said time counting circuit for detecting when time correction is to occur and for developing an output signal to indicate detection;
- time correcting means for detecting a time signal from said detecting means and correcting the time displayed by said timepiece circuit in response to the output of said correction time detector;
- preset memory means for storing contents representative of at least two broadcasting station frequencies and responsive to the operation of said station selecting means;
- and switching means for changing from one broadcasting station to a specified station capable of producing said time signal in response to the output of said correction time detector.
