Abstract: 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.

Abstract: An eyeglass lens processing apparatus for processing a periphery of an eyeglass lens includes: a lens chuck shaft configured to chuck the eyeglass lens; a shaft angle changing portion configured to change a shaft angle of the lens chuck shaft; a first processing tool unit including at least one spindle at which a first processing tool is provided; a second processing tool unit that is disposed to oppose the first processing tool unit and that includes at least one spindle at which a second processing tool is provided; and a controller configured to change one of the first and second processing tool unit to be used for processing the eyeglass lens to the other of the first and second processing tool by controlling driving of the shaft angle changing portion to change the shaft angle of the lens chuck shaft.
