Eyeglass lens processing apparatus

An eyeglass lens processing apparatus for processing an eyeglass lens, comprising:

• a lens chuck shaft which chucks the lens;
• a processing unit including a periphery processing tool for processing a periphery of the lens;
• a drilling unit including a drilling tool for drilling the lens;
• a mode selector for selecting an auxiliary lens processing mode processing an auxiliary lens after processing a normal lens, wherein the auxiliary lens is to be attached by a magnet to the normal lens held by an eyeglass frame,
• an eyeglass data input unit for inputting eyeglass data including a first target lens shape of the normal lens and a right target lens shape-to-left target lens shape distance;
• a hole position input unit which has a screen through which a position of a first hole, through which a first magnet is to be attached to the normal lens, is input;
• and
• a determination unit which determines, when the auxiliary lens processing mode is selected, a second target lens shape of the auxiliary lens, a position of a second hole through which a second magnet is to be attached to the auxiliary lens, positions of third holes to which a bridge connecting both right and left auxiliary lenses each other is to be attached,
• the determination unit determining the second target lens shape based on the first target lens shape,
• the determination unit determining the second hole position with respect to the second target lens shape based on the first hole position with respect to the first target lens shape, and
• the determination unit determining the third hole positions with respect to the second target lens shape based on the right target lens shape-to-left target lens shape distance and a separation distance between the third holes to be processed;
• and
• a processing controller which shifts to a stage of processing the auxiliary lens after a stage of processing the normal lens, processes a periphery of the auxiliary lens by controlling the processing unit based on the second target lens shape, and drills the auxiliary lens by controlling the drilling unit based on the second hole position and the third hole positions when the auxiliary lens processing mode is selected.
