Abstract
Abstract An electronic timepiece with a time signalling device wherein to the time signalling device is applied an output signal with a predetermined frequency which is produced from one of a plurality of cascade connected, bistable multivibrator stages in a divider which is used for dividing a high frequency signal into a standard time signal of low frequency. Further, a plurality of output signals produced from the corresponding stage are periodically and alternately applied to the time signalling device for enhancement of the tone of the time signalling sound.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
106 words
An electronic timepiece including a time signalling device and comprising a standard oscillator for generating a high frequency signal, a divider coupled to said oscillator and including a plurality of counting-down devices connected in cascade for sequentially and respectively dividing the high frequency signal from the standard oscillator into a plurality of different intermediate frequencies and into a standard time signal of low frequency, and a switching device for operating said time signalling device at a set time and for applying one of the frequencies produced by said counting-down devices selectively to said time signalling device thereby producing a time signalling sound with an audible frequency.
Claim 2
Dependent Claim
106 words
An electronic timepiece including a time signalling device and comprising a standard oscillator for generating a high frequency signal, a divider coupled to said oscillator and including a plurality of counting-down devices connected in cascade for sequentially and respectively dividing the high frequency signal from the standard oscillator into a plurality of different intermediate frequencies and into a standard time signal of low frequency, and a switching device for operating said time signalling device at a set time and for applying one of the frequencies produced by said counting-down devices selectively to said time signalling device thereby producing a time signalling sound with an audible frequency.
Claim 3
Dependent Claim
24 words
An electronic timepiece according to claim 1, wherein each said counting-down device is a bistable multivibrator for dividing the frequency applied thereto in half.
Claim 4
Dependent Claim
73 words
An electronic timepiece according to claim 1, wherein said divider includes a plurality of output terminals connected to at least some of said counting-down devices and means by which the frequencies produced at said output terminaLs are periodically and alternately applied to said time signalling device under control of a signal produced from one of the output terminals of said counting-down devices, thereby producing a time signalling sound with a plurality of tones.
Claim 5
Dependent Claim
50 words
An electronic timepiece according to claim 3, wherein two output signals produced at two output terminals adjacent of said counting-down devices are periodically and alternately applied to a time signalling device, thereby producing a time signalling sound with two tones which are one octave different in frequency from each other.
Claim 6
Dependent Claim
14 words
An electronic timepiece according to claim 1, wherein said oscillator is a quartz oscillator.
