Abstract: A lens stocking apparatus capable of stocking a plurality of lenses, which has a first stage, on which a plurality of trays respectively accommodating lenses are mountable, for transferring a tray, a vertically movable second stage, on which a plurality of trays respectively accommodating lenses are mountable by being vertically stacked, for receiving a tray, a tray movement unit that has a holding portion, which is adapted to hold a tray, and that is configured to move a tray from the first stage to the second stage, and a guide unit adapted to guide a position of at least a topmost one of trays mounted on the second stage.

Abstract: A grinding water treating apparatus for separating a processing refuse from grinding water used for processing a periphery of an eyeglass lens, the grinding water being introduced from an eyeglass lens processing apparatus, the grinding water treating apparatus includes: a centrifugal separator that includes a dewatering tank having a bottom surface and a side surface and a drive source for rotating the dewatering tank, and springs out the grinding water to an upper portion of the dewatering tank by rotating the dewatering tank; and a drain pipe that introduces the grinding water from an upper portion of the dewatering tank. The centrifugal separator includes a filter arranged at the upper portion of the dewatering tank and having an opening inserted with the drain pipe for filtering the grinding water separated from the processing refuse by a centrifugal force generated due to rotation of the dewatering tank.
