<p><P>PROBLEM TO BE SOLVED: To provide a data recording device, capable of automatically recording necessary data and using a small-capacity memory. <P>SOLUTION: The data recording device comprises a nonvolatile memory 10, and a control part 20 which performs writing processing of measurement data and order specification data to the nonvolatile memory 10. When at least one of data D1 of a first block written to a first storage area 11 of the nonvolatile memory 10 and data D2 of a second block written to a second storage area 12 thereof contains data of a value out of a predetermined range, the control part 20 writes new measurement data to the first storage area so that the data D1 and the order specification data assigned to D1 are not overwritten. When the data D1 and D2 do not contain the value out of the predetermined range, the control part 20 writes the new measurement data to the first storage area so that the data D1 and the order specification data assigned to D1 are overwritten. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
