PURPOSE:To count and display numbers easily and accurately through counters of >=2 systems by providing timer functions while providing counter's operation, which counts the operation frequency of an external operation member and displays the integrated value, as many as tow system. CONSTITUTION:In every time when a clock is inputted, decimal up/down counters 8-11 count by one on each input and wait a reset input and an up/down changeover input. In every time when a switch 1 is pushed, a clock is inputted from an L1I to the counter 8 and in every time when a switch 2 is pushed, the clock is inputted from an RI to the counter 10. An RL resets the counters 8 and 9, and an RR resets the counters 10 and 11 separated; counting-up operation is performed in +1 score counter state, and counting-down operation is -1 score state. This constitution counts and displays numbers easily and accurately by the counters of >=2 systems. |
