Zusammenfassung:	PROBLEM TO BE SOLVED: To simply measure an impact force of a heavy floor impact sound measuring instrument or the like by detecting an impact force of a dropped article and graph displaying its output in a time series manner. SOLUTION: A rubber tire of a heavy floor impact sound generator is dropped on an upper surface of an impact receiving member of a force detector. At this time, time series data corresponding to a digitized impact force of a composite output of three force sensors 1a to 2c is inputted to a CPU 8. The CPU 8 inputs the data, and displays an allowable range of the force selected by an operation of an allowable range changeover switch on a liquid crystal display unit 3d. When simultaneously input value falls within the allowable range, a character row 'OK' is displayed, while, when the value is not inputted, a character row 'NG' is displayed.
