Claims (1)

[Scope of utility model registration request] A three-dimensional automatic measuring machine used for measuring the dimensions of machined products includes a measurement probe that moves forward, backward, left, right, up and down, contacts the surface of the object to be measured, and detects coordinate points on the surface of the object to be measured; A probe reading/control device that reads and controls the output signal, an X-axis scale unit, a Y-axis scale unit, and a Z-axis scale unit that detect the amount of movement of the measurement probe in the front, back, left, right, and up and down directions; An X-axis drive device, a Y-axis drive device, a Z-axis drive device for moving the measuring probe back and forth, left, right, up and down, a measuring device control means for controlling each scale unit and each device, and a measurement data processing means for calculating various measured dimensions of the measurement probe; an optical displacement sensor provided on the measurement probe for detecting vertical displacement between the surface of the object to be measured and the measurement probe; a displacement detector for detecting the amount of displacement by inputting an output signal; a detector control means for reading the amount of displacement detected by the displacement detector and controlling the displacement detector; hole detection means for determining the presence or absence of a hole on the surface of the object to be measured based on the amount of displacement; designated hole determination means for determining whether the hole detected by the hole detection means is a hole that should originally be at that position; A three-dimensional automatic measuring machine comprising a CPU, a memory, an input device, a display device, a printing device, and a computer having an interface for executing each means.
