Title:
SPECTACLE LENS PROCESSING DEVICE
Document Type and Number:
Japanese Patent JP2014233789
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To perform processing of a spectacle lens with a simple structure.SOLUTION: The spectacle lens processing device comprises: a processing tool for performing processing of a spectacle lens; a first rotation mechanism for rotating a pair of lens chuck shafts around a shaft, the lens chuck shafts holding the spectacle lens directly; a first drive part for driving the first rotation mechanism; and a first control part for controlling the first drive part. The spectacle lens processing device performs processing of the spectacle lens on the basis of ball type data and layout data. Based on a detection result detected by a mark detection unit for detecting a mark provided on the spectacle lens for regulating at least one of an optical center and a reference direction of an astigmatism shaft of the spectacle lens, the optical center determined by the optical center of the spectacle lens held by the lens chuck shafts and the layout data is registered, and/or the reference direction of the astigmatism shaft of the spectacle lens held by the lens chuck shafts and the reference direction of the astigmatism shaft based on the ball type data are registered by registration means.
