(assignment)
Without processing the syntax dependent on the conductivity, there is provided a calibration sensor unit capable of performing the correction with high accuracy.
[MEANS FOR SOLVING PROBLEMS]
A spectacle lens machining apparatus has a lens and cheokchuk, sphere and processing to process the peripheral edge of the lens, and obtain the processed clause is mounted machining rotating axis. Calibration sensor unit for calibrating the eyeglass lens processing apparatus, the contact member in a second direction perpendicular to the contact member, a first direction of the lens cheokchuk direction in contact with the fixing part, and a processing sphere mounted to a lens cheokchuk a support mechanism which is movably supported, and a support mechanism and, and for detecting the contact of the working sphere of the contact member sensor, a detection signal of the sensor in a direction away for the government has an elastic support member for elastically supporting the contact member a signal transmitting unit for transmitting the ophthalmic lens processing apparatus, and an elastic support member, the elastic contact member is not to be contacted to and processed old when moved to jeongbucheuk bend the rotating shaft and the lens cheokchuk to or greater than a predetermined tolerance of the processing obtain It has a retention force.
