<p>PROBLEM TO BE SOLVED: To provide a method for recording data by which data update is surely performed. SOLUTION: When the data is newly inputted from a data input part 16, a CPU 11 performs a recording processing to record the inputted data in a recording area of a memory 13. The memory 13 has two recording areas capable of recording two kinds of data. And in the case of the recording processing, the CPU 11 preferentially records the inputted data irrespective of presence/ absence of a free area in which the inputted data can be recorded in the recording area. In addition, when the existing data exists in the recording area, the CPU 11 sorts the existing data and the inputted data into two kinds of types from relation between the current date and time and date and time information of the existing data and the inputted data. And the CPU 11 determines the recording area in which the inputted data should be recorded according to presence/absence of the existing data and the relation between the types of the inputted data and the existing data.</p> |
