    • PURPOSE:To shorten a correction time by stopping writing to an electrochromic display part when the generation interval of a correction pulse is less than a specified time. CONSTITUTION:When a correction switch 24 is operated only once, a timer circuit 10 is corrected by a correction pulse signal C and at the same time, an erasure pulse E is outputted to clear the display of an ECD16. Then, a write pulse 0 is outputted to write and display a corrected time on the ECD16. When the correction switch 24 is operated successively serveral times, an AND gate 22 outputs the correction pulse signal C continuously and the count value of the timer circuit 10 is corrected. An FF32 is set by the 1st leading edge of this correction pulse signal C and the erasure pulse E is outputted continuously. Then, when the correction switch 24 is operated at the interval long enough for a hexadecimal counter 42 to finish counting, a write pulse generating circuit 54 outputs the write pulse and the corrected time is displayed on the ECD16.
    • 目的:当校正脉冲的产生间隔小于指定时间时,通过停止写入电致变色显示部件来缩短校正时间。 构成:当校正开关24仅操作一次时,通过校正脉冲信号C校正定时器电路10,同时输出消除脉冲E以清除ECD16的显示。 然后,写入脉冲0被输出以在ECD16上写入和显示校正的时间。 当校正开关24连续运行时,与门22连续输出校正脉冲信号C,校正定时电路10的计数值。 FF32由该校正脉冲信号C的第1前沿设定,消除脉冲E被连续输出。 然后,当校正开关24以十六进制计数器42完成计数足够长的间隔操作时,写脉冲发生电路54输出写入脉冲,并且校正时间显示在ECD16上。
