Abstract

PURPOSE: To reduce working time in a grinding plate for lens work by receiving the pressing force from the main unit side through a bag body using the pressure surface of a moving plate and uniformly pressing a worked lens using the whole surface of a grinder.
CONSTITUTION: A moving plate 72 which is opposed to a sealed plate 5 receives the pressing force (P) from an ornamental hairpin 1 and a pellet plate main unit 71 transmits it (P) through a rubber bag body 73. Therefore, the rubber bag body is compressed and flat. In this case, the pellet plate main unit 17 approaches to the moving plate 72 by the specified amount. When a uniform pressure type pellet plate 7 elliptically moves in this state, the pellet plate main unit 71 receives moment (M) and centrifugal force (F) due to the deviation of the gravity (G) at the center of the ornamental hairpin connection hole 711 and is inclined, as shown by two dotted lines. At this time, the moving plate 72 receives uniform pressing force P1 from the rubber bag body 73 using the whole pressure surface 722. As a result, a grinder surface (A) is uniformly pressed by the working surface (C) of a worked lens and uniform grinding work is performed.
