PURPOSE:To form a multi-functional stopwatch simple in a manipulation method, by simultaneously displaying a clocking result and an operation result at the point of time of input manipulation as two different displays by one input manipulation. CONSTITUTION:A counter circuit 9 starts counting by input 4 and reference clocking 1 is displayed by a display apparatus 11. When first input 5 succeeding to the input 4 is issued, the counted value of the counter circuit 9 at the moment of the input 5 is latched by a latch A and displayed as split clocking 2 which is also first lap clocking 3. When the input 5 is again issued, the counted value of the counter circuit 9 at the moment of the input 5 enters the latch A while the value previously latched in the latch A is transferred to a latch B and the counted value of the latch A is displayed as the split clocking 2. The counted values of the latch A and the latch B are inputted to an operation circuit 14 to perform subtraction and the obtained value is displayed as the lap clocking 3. Two kinds of clockings of the split clocking 2 and the lap clocking 3 are performed similarly and so forth to continue display. |
