Abstract: An automatic measuring apparatus includes a measuring device that measures a dimension of a workpiece, the measuring device including a movable element that is displaceable with respect to a fixed element and moves forward and backward to be brought into contact with or away from the workpiece, and a displacement detection part that detects a displacement or position of the movable element, and an automatic operation part that automates the forward/backward movement of the movable element by power. A workpiece holding part that holds the workpiece in such a manner that a position and posture of the workpiece is changed at a pressure lower than a predetermined measurement pressure set in advance in the measuring device when the movable element is brought into contact with the workpiece.

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: There is provided an inside-diameter measuring unit capable of automating inside-diameter measurement and a control method for automatic inside-diameter measurement. An inside-diameter measuring part is supported by a support frame part via a floating joint part. The floating joint part includes a rotation-allowing mechanism part and a translation-allowing mechanism part. A measuring head part of the inside-diameter measuring part is inserted into a hole by a robot arm part. The inside-diameter measuring part adjusts its position and posture autonomously by the reaction force when a contact point pushes against the inner wall of the hole to align the axis of the inside-diameter measuring part with the axis of the hole. An electric inside-diameter measuring unit can automatically measure the inside diameter of a hole.

Abstract: There is provided a display panel module unit having a narrow frame suitable for a display unit of a small-sized measuring apparatus. A panel module unit includes a first panel part, a second panel part, and an intermediate cover housed in a housing part in order from a front side to a rear side. The housing part includes an annular side wall and at least one fixing means attached on an inner peripheral surface of the side wall, and the fixing means is a means for fixing a position of the intermediate cover in the housing part. The second panel part is housed between the first panel part and the intermediate cover, and a position of the second panel part is indirectly fixed by the intermediate cover. The second panel part is provided with a biasing means for biasing the first panel part from the rear side toward the front side.
