Patent DE-2728525-A1 (DE)
Inventor: KASHIO TOSHIO
IPC: G04G3/02
Filed: 1977-06-24
Abstract: An electronic timepiece uses a dynamic type shift register, as a time count circuit, which has a plurality of memory sections corresponding to an equal number of time count units and a cycle number memory section arranged such that it is preceded by said plurality of memory sections. An adder and shift memory unit are serially connected to the shift register to provide a shift circulation circuit and the shift circulation is effected by an oscillation signal from a reference oscillator. The adder adds [1] to the contents of the cycle number memory section for each data shift cycle of the shift register. Each time the count value of the cycle number memory section reaches a predetermined cycle number, the count value of a smallest time unit is counted one step. In this way, a carry is propagated to the subsequent large time unit memory sections according to the data shift circulation cycle of the shift register. A memory circuit is also provided which preliminarily stores a correction value corresponding to an error occuring between the oscillation frequency of the reference oscillator as generated per unit time and the standard oscillation frequency which drives the shift circulation circuit. Upon receipt of a correction timing signal the memory circuit has its correction value substracted at a rate of one circulation cycle per minute, thereby to correct such an error. The correction value indicates a total number of subtractive circulation cycle per hour.
