  • Patent number: 6845678
    Abstract: A spectacle frame shape measuring apparatus includes a measurement element holding mechanism. The measurement element holding mechanism holds a measurement element in a substantially loadless state along a frame groove formed in the inner circumferential surface of a rim of a spectacle frame. The measurement element holding mechanism includes a rod, balance spring, and evacuating mechanism. The rod is vertically movable and has an upper end portion on which the measurement element is mounted. The balance spring pushes the rod upward to hold the measurement element at a loading position during shape measurement. The evacuating mechanism regularly evacuates the measurement element to an evacuation position, thereby performing three-dimensional measurement of a rim shape. A spectacle frame shape measuring apparatus holder is also disclosed.

  • Patent number: 6621564
    Abstract: The invention provides an automatic lens meter comprising an optical system forming a pattern image by projecting a pattern created by a pattern creating member and measuring optical properties of a lens based on the displacement of the pattern image from a baseline position wherein the examined lens is not in the path of rays in the optical system to a measuring position wherein the examined lens is in the path of the rays. The lens meter includes an image sensor for detecting the position of the pattern image using four line sensors 10a, 10b, 10c and 10d disposed on a pattern image forming plane and arranged in a cross shape, and the pattern creating member forms a pattern image having a quadrangular shape on the pattern image forming plane so that each line sensor intersects a side of the quadrangle, thereby facilitating accurate measurement of desired optical properties.

  • Patent number: 6328630
    Abstract: The following was done in order to mechanically polish a bevel face after bevel finishing without manually polishing and thereby speed up the polishing process and improve uniformity of finishing precision, as well as obtain fashionable eyeglasses: That is, a polishing wheel for polishing a bevel with a bevel polishing groove the shape of which essentially matches the bevel faces of the finished lens is used. The bevel is polished in two processes using said wheel. During the first process, the apex position of the bevel in the finished lens is displaced from the bevel-groove center position of the bevel polishing groove in the wheel to the concave side of the lens and the polishing allowance on the concave side of the bevel faces is polished.
