Patent number: 6845678Abstract: 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.Type: GrantFiled: April 7, 2003Date of Patent: January 25, 2005Assignee: Hoya CorporationInventors: Takashi Igarashi, Hisanori Akiyama, Masahiro Jinbo, Ryosuke Sato, Takashi Daimaru

Patent number: 6328630Abstract: 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.Type: GrantFiled: October 4, 1999Date of Patent: December 11, 2001Assignee: Hoya CorporationInventors: Masahiro Jinbo, Takashi Daimaru
