PURPOSE: To improve the working efficiency and accuracy of the title device by allowing a computer to automatically execute comparing/deciding work between an inspected result which is ordinarily executed by a person with a reference result.

CONSTITUTION: A value comparing/deciding means 14 converts inputted character information 1 and character information 2 to be compared inputted from an additional reference result storing means 18 respectively into numerical information 1 and numerical information 2 by using e.g. a FORTRAN leading format. When the absolute value of a difference between the numerical information 1 and the numerical information 2 is smaller than an allowable error found out from an allowable error ratio applied from an allowable error ratio input means 11, coincidence is decided, and at the time of a larger absolute value, discrepancy is decided. On the other hand, a character comparing/deciding means 15 directly compares character information 1 decided as a character with character information 2 to be compared and decides whether both the information 1, 2 coincide with each other or not. The prescribed edition of these compared/decided results is executed by a decided result output means 16 and outputted as a compared/decided result output 19. Since all processing can be executed using a computer, accurate and automatic processing can be attained.
