Title:
SPECTACLE LENS PROCESSING DEVICE
Document Type and Number:
Japanese Patent JP2016147365
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a spectacle lens processing device which obtains measurement data of a spectacle lens refraction surface by storing a control position of a spectacle lens holding part at the time of contact of a probe detecting contact of the refraction surface of the spectacle lens.SOLUTION: A spectacle lens processing device comprises: a spectacle lens holding part which holds a spectacle lens so that rotation control can be performed thereto; a processing tool part which holds a rotation processing tool so as to be capable of rotating around an axis; a control drive part which can control the relative physical relationship between the lens holding part and the processing tool part in an axial parallel direction; a control drive part which can control the relative physical relationship in an inter-axis distance direction; and a spectacle lens refraction surface contact detection part. The spectacle lens processing device obtains the shape measurement value of the spectacle lens refraction surface from the movement control amount at the time of contact detection of the spectacle lens refraction surface.SELECTED DRAWING: Figure 10b
