  • Patent number: 11639848
    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.

  • Patent number: 9776293
    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.

  • Patent number: 8506352
    Abstract: An eyeglass lens processing apparatus for processing a peripheral edge of an eyeglass lens, includes: a processing unit including a plurality of processing tools that process the peripheral edge of the eyeglass lens held by a lens chuck shaft; a calibrating lens; a mode selector that selects a calibration mode; a memory that stores calibration processing data for processing the calibrating lens to a predetermined shape; a detecting unit that includes a tracing stylus that contacts a surface of the calibrating lens which is processed by the processing unit based on the calibration processing data to detect the shape of the processed calibrating lens in the calibration mode; and a calculating unit that obtain calibration data by comparing a detected result by the detecting unit with the calibration processing data in the calibration mode.

  • Patent number: 8448343
    Abstract: An eyeglass lens processing apparatus includes lens chuck shafts, processing tools for processing a lens and processing tool rotating shafts to which the processing tools are attached. A calibration sensor unit for calibrating the eyeglass lens processing apparatus includes: an attachment portion attached to the lens chuck shafts; a contact member contacting the processing tools; a support mechanism configured to movably support the contact member and has an urging member that urges the contact member in a direction separating from the attachment portion; and a sensor that detects the contact of the contact member with the processing tools. The urging member has an urging force by which the processing tool rotating shafts and the lens chuck shafts are not bent to a predetermined tolerance or more when the contact member contacts the processing tools and is moved toward the attachment portion.
