PURPOSE: A calibration sensor unit of an eyeglasses lens processing device is provided to calibrate the position relation of a lens chuck shaft and a processing tool at high accuracy regardless of the conductivity of a processing toll and processing tool rotating device. CONSTITUTION: A calibration sensor unit of an eyeglasses lens processing device comprises a fixing unit(610), a contact member(620), a supporting tool, a sensor, and a signal transmitting unit(650). The fixing unit is installed to a lens chuck shaft(102L). The contact member is touched with a processing tool. The supporting tool movably supports the contact member toward a second direction across a first direction corresponding to the direction of a lens chuck shaft. The sensor detects the contact of the contact member and processing tool. The signal transmitting unit transmits a sensor signal to a glasses lens processing device. |
