Abstract: Disclosed are pliers for suction cup capable of removing easily a suction cup from an eyeglass lens. The suction cup includes a lens holding portion for holding the eyeglass lens and a mounting base formed integrally with the lens holding portion. The pliers comprise first and second pinching portions relatively movable close and apart to each other for pinching the mounting base, opposed surfaces formed on the first and second pinching portions to oppose the mounting base, and an engaged convex portion provided on at least one of the opposed surfaces of the first and second pinching portions to contact with the mounting base.

Abstract: A lens shape measuring apparatus is disclosed, which is capable of identifying a size of an outer-diameter shape of a lens fixing jig by using a measuring element also used for measuring a lend shape. This lens shape measuring apparatus comprising: a lens fixing jig installed in an eyeglass lens to be processed to clamp the eyeglass lens; a lens rotation shaft for clamping and rotating the lens to be processed; a measuring element abutted on a refracting surface of the lens clamped by the lens rotation shaft; a measuring element position switching mechanism for controlling rotation of the measuring element around a rotation shaft roughly parallel to the lens rotation shaft; and a measuring unit for measuring a moving distance of the measuring element in a direction roughly parallel to the lens rotation shaft.

Abstract: An initial position setting method for grinding work apparatus includes: a grind stone 11; a pair of lens rotating shafts 14, 14 which are capable of approaching and drawing apart each other along a normal line of the grind stone 11; a ditch excavation grind stone 23 and chamfering grind stones 24, 25. A measurement standard 70 with a predetermined shape is adapted to be held by the lens rotating shafts 14, 14. The ditch excavation grind stone 23 and the chamfering grind stones 24, 25 are adapted to be moved to the predetermined position.

Abstract: Disclosed is a grinding fluid supply device of a lens grinding apparatus. The grinding fluid supply device includes first grinding fluid supply means for supplying a grinding fluid in a tangent direction of a circular grinding wheel, which has a grinding surface formed on its circumferential surface, with an interval above a grinding surface and allows an upper portion and a rear side portion of the grinding surface to be covered with a curtain of the grinding fluid spaced from the grinding wheel when a processed lens is subjected to a grind processing with the grinding surface of the grinding wheel by rotatively driving the grinding wheel around an axis; and second grinding fluid supply means for insufflating the grinding fluid to the grinding surface.

Abstract: The present invention relates to an apparatus for displaying a contour of a lens-shaped template formed to be fit in a lens frame of an eyeglass frame. The contour is displayed on a display in a same size of a real lens-shaped template. The apparatus includes a display for displaying a cross-sectional V-shaped edge figure, a position, and a thickness at an arbitrary point of the contour. The invention also relates to an apparatus for displaying a lens shape. The apparatus includes first display means for displaying a contour of a lens-shaped template formed to be fit in a lens frame of an eyeglass frame, second display means for displaying a cross-sectional V-shaped edge figure at an arbitrary point of the contour, and third display means for displaying a first mark indicating a position of the contour corresponding to positions of at least two edge figures displayed by the first display means.
