Title:
CENTERING DEVICE
Document Type and Number:
Japanese Patent JP3929595
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To judge working propriety before attaching a cup by a simple constitution by performing the centering for attaching the cup while observing the image of a lens to be worked inputted and displayed on a display.
SOLUTION: An operator moves the lens LE to be worked on a screen plate 3 so as to match a mark point-marked image of the center of a mark point image with the center of a cross reticule mark while observing the display 22 of a lens working device 20. Also, the lens LE to be worked is rotated and axis accuracy is matched so as to overlap the left and right marked images of the mark point-marked image with the horizontal line of the cross reticule mark. Thus, the centering of the lens LE to be worked is completed. The operator judges the working propriety of whether or not a lens diameter is insufficient by observing the diameter of a lens image and a lens-shaped graphic at the time. Then, when it is judged that the diameter of the lens to be worked is not a problem, the cup C is attached by a cup attachment part 10.
