PURPOSE:To easily judge the difference between a reference value and a measured value by providing a means to read plural inspection data from a recording medium, means to calculate a decision reference, means to display it and means to write the decision reference to the recording medium. CONSTITUTION:In a program stored in a memory 3-3, the read processing instruc tion of the reference value is sent from an interface 3-2 to an optical card reader/writer 2 by a CPU 3-1 and the latest reference value is read and devel oped on the memory 3-3. Samely, the measured value is developed on the mem ory 3-3 according to the read instruction as well. When a + key is pushed, the new reference value is calculated from the fetched measured value, written into an optical card 1 and displayed in a display device 5 together with the measured value. When the + key is not pushed, the latest reference value and the measured value are displayed as they are. |
