Abstract
An automatic timepiece calibrating device which utilizes the time signal given by any broadcasting station to provide calibration automatically once every 24 hours, a logic electronic timer device being adapted to switch on a receiver once in every 24 hours so that the receiver will generate an impulse immediately after receipt of a time signal from a broadcasting station. The time signal is passed by means of a tuning circuit and converted to impulses which are counted and, if the count corresponds to the signal the counter output impulse resets the internal state of electronic timepiece so that the time display is restarted from zero.
Claims5
An electronic timepiece calibrating device comprising, in combination, a receiver for receiving a time signal from a broadcasting station, an electronic timepiece having resetting means for returning said timepiece to a zero setting, means controlled by said electronic timepiece for energizing said receiver, means connected to said receiver for converting the time signal from said receiver to a series of impulses, means for counting said series of impulses and for generating an output pulse when said series of impulses correspond in number to the frequency of said time signal and means for feeding said output pulse to said electronic timepiece to actuate said resetting means.
