Patent ID: 8387224

Claim:
A spectacle lens measuring and machining device, comprising: a distance measuring device for measuring a distance between a frame center forming a block center in an edging for manufacturing the spectacle lens from a raw material lens and an edge face of said spectacle lens, including an error produced in said edging; a lens thickness measuring device for measuring the lens thickness at a mounting part-machined portion in the spectacle lens where the mounting part for mounting spectacle frame components is machined; a lens feeder for feeding the spectacle lens to the lens thickness measuring device; a machining device including a machining tool which advances from the edge face of said spectacle lens toward an inside of the lens, and for machining said mounting part to said spectacle lens with the machining tool; a controller for controlling said lens feeder and said machining device, to control feeding of said spectacle lens to said lens thickness measuring device by said lens feeder based on data on said distance which is inputted from said distance measuring device, and not to drive said machining device when data on said lens thickness is inputted from said lens thickness measuring device and the lens thickness found to be less than the specified value, and to drive the machining device when the lens thickness is equal to or larger than the specified value.
