DETECTOR, SURFACE PROPERTY MEASURING DEVICE AND ROUNDNESS MEASURING DEVICE

摘要

A detector, a surface property measuring device and a roundness measuring device for automatically measuring a plurality of surfaces are provided in order to shorten the time required for the measurement. This problem is solved by a detector that has a contact holding probe that comes into contact with a surface of a measurement object, a holder that is configured to hold the probe, a measuring section that is configured to hold the holder hold that is in position to pivot about a rotary shaft and detect displacement of the holder, and includes a body configured to receive the measuring section, the holder holding the sensor so that a sensor axis as an axis of the Sensor and a body axis as the axis of the body are parallel, and the sensor axis and the body axis are offset in a first direction perpendicular to the body axis and the rotating shaft.
