Abstract
PURPOSE: To seize an article in between or release it simply and certainly and to improve accuracy of its grinding, by expanding and closing of a seizing member through the relative rotation between the seizing member and the outer ring.
CONSTITUTION: When the grinding work is finished, the engagement of the seizing member 1 with the ratchet gear 1d is released by taking away the seizing device from the recess pan along with the lens 3 and, further, by pushing the stop valve 4 against the spring force, and then the seizing member 1 and the outer ring 2 are rotated relatively to each other in the direction opposite to that when they are seizing the lens 3 to move continuously toward the large diameter section the periphery 2a of the outer ring 2. This shift expands the lens seizing member 1 by its own elasticity and removes the lens 3 from the seizing device.
