PROBLEM TO BE SOLVED: To calculate and display the operation rate of a component mounting device based upon standards corresponding to user's desire by calculating the operation rate from an inputted mathematical expression. SOLUTION: On the display screen of a display 16, the mathematical expression that an operator has inputted on a keyboard 18 is displayed. Here, constants, operational symbols, and variables are inputted and the operator continues to input the mathematical expression and corrects and confirms it while locking at the displayed mathematical expression. This inputted mathematical expression is an expression for calculating the operation rate that a user refers to for line monitoring. A CPU 10 calculates the operation rate of the component mounting device from the set mathematical expression data, constant data, and various data data inputted from the component mounting device through an I/F 19 and a communication line, and displays the calculated operation rate data on the display 16 according to a specific display form. Thus, the operation rate is calculated from the optionally given mathematical expression and the calculation result is displayed. |
