Abstract
PURPOSE:To accurately measure the operating time of a vehicle without particular operation by detecting an engine key closed and measuring the time duration while the engine key is closed. CONSTITUTION:When an engine key is closed, an AND gate 19 is opened to cause an auxiliary watch device 26 to count carry signals dispatched at every one minute from a sexagesimal counter 12 to thereby measure the operating time of the engine. When the vehicle is stopped for long time without necessity of measuring the operating time, a counter 27 detects the state to thereby clear the device 26. the carry signal dispatched at every one minute is also applied to watch counters 13-15 to thereby display normal clock time.
