CONSTITUTION: A first counting circuit 103 consists of a first counting part 101 and a second counting part 102, a master clock is inputted to the first counting part 101, a counting operation is executed, output (a) is inputted from the fixed counting stage of the first counting part 101 to the second counting part 102, the counting operation is executed, output (b) of the final stage of the first counting circuit 103 is inputted to a second counting circuit 104 and the counting operation is executed. Then, the output (b) of the final stage of the first counting circuit 103 is inputted to a reset means 105, the first counting circuit 103 is reset and the output of the respective counting stages of the second counting circuit 104 after resetting is changed at different timing.
