Abstract

PURPOSE: To obtain accurate measured data with the use of a simple construction by measuring the operating force and lock position of a push button with the use of an operating member and detecting means.
CONSTITUTION: When a preset push button 3 is disposed at such a position as to face the operating member 25 of a preset tester, the cam portion 44 of a cam plate is made to move down the member 25 through a roller 19 and a shaft 23 by the rotations of a motor, thereby to push down the push button 3. The operating force required to depress the push button is detected by first detecting means 26 which is interposed between the shaft 23 and the member 25. When the operating force is stronger than the bias force of a spring 34, the relative positions between the shaft 23 and the cylinder 12 are varied so that the malfunction is detected by third detecting means 28. When the locked condition is released by the operation of the release button, the operating force and the existence of the malfunction are detected at the push button 3 by means 26 and 28. Thus, the accurate data can be easily obtained.
