した測定装置の実現が必要であった。In general, micrometers are widely used to precisely measure the outer dimensions or outer diameter dimensions of an object to be measured. Manually measuring and inspecting a large number of objects with this micrometer requires 1,000 kilometres, lengthens the measurement time, and is inefficient. Therefore, in most cases, a sampling inspection is sufficient. However, in the assembly of precision machines, it is expected that the accuracy of individual parts will be improved even more. In order to obtain quick and reliable measurement results of the object to be measured, there was a demand for automation of the measuring device, but as it becomes more sophisticated, it becomes more expensive, so it was necessary to create a measuring device suitable for on-site inspection. .
