Abstract: An automatic measuring apparatus includes an inside-diameter measuring unit that measures the inside diameter of a workpiece, a robot arm part, and a control unit. The inside-diameter measuring unit is installed with the tip side facing upward. A cone-shaped guide cone is provided at the tip of the inside-diameter measuring unit. A workpiece stopper is attached to the outside of the inside-diameter measuring unit. A support surface, which serves as a placing surface on which the workpiece is placed, is supported by a spring, and the inclination and position of the support surface changes to follow a change in the posture and position of the workpiece.

Abstract: An automatic measuring device includes a micrometer including a spindle that moves forward and backward to be brought into contact with or away from a workpiece and a displacement detector unit that detects displacement of the spindle, and an automatic operation unit that automates the forward and backward movement of the spindle by power. The automatic operation unit performs a first forward-movement step of moving the spindle forward to bring the spindle into contact with the workpiece, and a contact determination step of determining the contact between the spindle and the workpiece in the first forward-movement step. In the contact determination step, the spindle is determined to be in contact with the workpiece when a change in a position of the spindle detected by the displacement detector unit in the first forward-movement step becomes equal to or less than a predetermined contact determination threshold.

Abstract: A displacement measuring instrument includes an encoder that detects the amount of moving displacement of a measuring element while the measuring element is in contact with the surface of an object to be measured, a calculator that calculates a measurement value, and a display that displays at least the measurement value. The calculator includes a measuring section that calculates the measurement value from the amount of moving displacement and displays the measurement value on the display, a speed acquiring section that acquires the speed of the measuring element, an approach analyzing section that analyzes and determines whether the approach of the measuring element to the object to be measured is appropriate or inappropriate, and a warning section that issues a warning when the approach analyzing section determines that the approach of the measuring element to the object to be measured is inappropriate.
