PROBLEM TO BE SOLVED: To reduce a writing amount and thus reduce the entire period of time for writing by dynamically compressing input data. SOLUTION: The device is equipped with an input processing part 11 for reading data from an input source such as an external device 20 and storing the data in an input data arrangement memory part 11a, a compression processing part 12 for reading the data in the input data arrangement memory part 11a stored by the input processing part 11 and performing compression processing, a storing processing part 13 for storing the compressed data compressed by the compression processing part 12 in a storage device 21, and a setting processing part 14 for setting operation/function of the input processing part 11 and the compression processing part 12. The input processing part 11 collects/stores a data to be classified into a bit data and a numerical value data and the data are compressed by the compression processing part 12. The compression processing part 12 classifies the input information into the bit data and the numerical value data, performs input value estimation from the characteristic of each data in a time sequence, obtains the difference between the data and an actual input value, represents a difference value with high appearing frequency by a short sign and deletes the data amount.
