摘要： An eyeglass frame shape measurement device includes an optical measurement unit, a probe unit, a holding unit that holds the optical measurement unit and the probe unit, a changing portion that integrally moves the optical measurement unit and the probe unit with respect to an eyeglass frame to change a measurement position with respect to a groove of a rim of the eyeglass frame, and a controller that controls an operation of the eyeglass frame shape measurement device. The controller controls an operation of the changing portion to measure the groove of the rim of the eyeglass frame, acquires a cross-sectional shape of the groove of the rim of the eyeglass frame based on a detection result detected by the optical measurement unit, and acquires a shape of the rim of the eyeglass frame based on a detection result detected by the probe unit.
