Summary:PURPOSE:To surely recognize a registered user and to easily correct the breakage of a data base and altered data by providing an operator discriminating means, plural data bases, a data check means, a data correcting means, etc. CONSTITUTION:A processor 21 compares an input ID code and a password with the codes and passwords of a memory 24 and 25 respectively for discrimination between a normalized operator and the general operators and outputs the normal and general trigger signals. A processor 31 receives these trigger signals to give accesses to data bases 32-34 and reads out data to display them on a display 36. At the same time, the processor 31 carries out the program operation of an abnormal data correcting means based on a command given from a keyboard 35. A data comparing means 41 compares the data on the bases 32-34 with each other and an abnormal data deciding means 42 decides an abnormal base data when no coincidence is obtained from said comparison. A data correcting means 43 uses the data on the data base having the highest weighting to correct the abnormal data on the relevant data base.
