準時刻に一致する従属時刻を表示する子時計より成る親
子電気時計において、親時計側に発振回路の出力を分周
して巾の異なるパルスを得る手段を設けると共に、前述
パルスを選択し、この選択信号によって親時計の表示器
の表示を修正する手段を設け、子時計側に同様に前述パ
ルスを選択し、この選択信号によって子時計の表示器の
表示を修正する手段を設けて成る親子電気時計。In a parent-child electric clock consisting of a master clock that displays standard time and a slave clock that displays slave time that matches the standard time using a signal from the master clock, the output of the oscillation circuit is divided on the master clock side to generate pulses of different widths. In addition to providing means for selecting the aforementioned pulse and correcting the display on the display of the master clock using this selection signal, similarly selecting the aforementioned pulse on the slave clock side and using this selection signal to modify the display of the slave clock. A parent-child electric clock comprising means for correcting the display on the display.
