| 摘要 | PURPOSE: To facilitate the correction of time, by stopping display by a time indicator, presetting the time and correcting the time depending on the difference from reference time. CONSTITUTION: Gates 30, 31 are opened through a switch 7 and a flip-flop 23. Other flip-flops 24, 25 are set by a registration key input detection signal which is supplied from a detection circuit 18 and passed through the gate 30. The indicator 3 of a secondary timepiece is stopped in response to the closing of other gates 43, 44. When presetting is performed through a registration key depending on the stopped display on the indicator 3, preset time is stored into a memory circuit 15 by an output generator 13 and displayed on the indicator 2 of a primary timepiece through a selector circuit 11. The display on the indicator 2 is replaced by an indication based on a time circuit 10 through the output generator 13 depending (result of) on the operation of an execution key. At that time, the result of time measurement by the time circuit 10 is stored into another memory circuit 16. The stored contents of the memory circuits 15, 16 are compared with each other to detect delay or gaining. The display on the indicator 3 is corrected through a calculation circuit depending on the delay or gaining. Time can thus be corrected by easy operation. COPYRIGHT: (C)1980,JPO&Japio |
