PROBLEM TO BE SOLVED: To enable even an inexperienced operator to input the correct data by deciding whether the input data have the standard specifications based on the standard specification data which are stored in a specification storage part and then outputting the contents of the said decision if they have no standard specifications. SOLUTION: An input device 1 inputs the data on the price decision factors, and an arithmetic unit 3 decides whether the input data have the standard specifications which are previously stored in a specification storage part 21. If the input data have no standard specifications, the contents of the decision are outputted to an output device 4. Then the said decision processing is repeated until it's decided that all input data have the standard specifications. The unit 3 calculates the price of a unit printed circuit board based on the data and the processing procedure which are stored in a price storage part 22. The calculated price is outputted to the device 4. Thus, even an operator who does not know the standard specifications in detail can surely input the data and therefore the reliability of the data is improved. |
