PURPOSE:To input the continuous digital data to memory, by using the digital input device performing sampling based on the synchronizing signal and the multiplexer distributing the synchronizing signal changed with the alteration of data renewal into a plurality of signals. CONSTITUTION:A digital output device 7 outputs the start/stop signal S4 based on the output request from the computer 3. When the request of data input is present from the computer 3, digital input devices 4 and 5 respectively sample the data D1 in the synchronism of synchronizing signals S2, S3 and store the data to the memory in the computer by DMA transfer. The multiplexer 6 starts the operation when the start/stop signal S4 is in start state, and shares the synchronizing signal S1 in synchronizing with the renewal of data D1 into S2 and S3 every number N suitably determined. That is, S1 is shared into S2 and S3 every N. |
