Abstract

A lens inspection device used for layout inspection of an edged lens edged in accordance with a shape of a spectacle frame, and having a layout inspection mark affixed to a lens surface, the lens inspection device includes a support unit that supports the edged lens, an imaging unit that takes in an imaged image including a visible outline of the edged lens and the layout inspection lark by imaging the edged lens supported by the support unit, a monitor that displays the imaged image taken in in the imaging unit, and a display control unit that displays, on the monitor, a lens outline reference line indicating a position to which the visible outline of the edged lens included in the imaged image is positioned, and a layout reference mark indicating a position where the layout inspection mark is arranged, together with the imaged image.

First claim

1 . A lens inspection device used for layout inspection of an edged lens edged in accordance with a shape of a spectacle frame and having a layout inspection mark affixed on at least one of lens surfaces, the lens inspection device comprising:
a support unit configured to support the edged lens; imaging means configured to take in an imaged image including a visible outline of the edged lens and the layout inspection mark by imaging the edged lens supported by the support unit; a monitor configured to display the imaged image taken in in the imaging means; and display control means configured to perform control to display, on the monitor, a lens outline reference line indicating a position to which the visible outline of the edged lens included in the imaged image is positioned, and a layout reference mark indicating a position where the layout inspection mark is arranged, together with the imaged image.

2 . The lens inspection device according to claim 1 , wherein
the display control means displays the lens outline reference line by double lines that define a positioning allowable width of the visible outline of the edged lens.

3 . The lens inspection device according to claim 1 , wherein
the display control means displays a determination reference line indicating an allowable range of positional deviation of the layout inspection mark with respect to the layout reference mark on or near a display position of the layout reference mark.

4 . The lens inspection device according to claim 1 , wherein
the display control means displays a scale for visually confirming a positional deviation amount of the layout inspection mark with respect to the layout reference mark on or near a display position of the layout reference mark.

5 . The lens inspection device according to claim 1 , comprising:
storage means configured to store image data displayed on the monitor when position adjustment of the edged lens is performed using the lens outline reference line and the layout reference mark, in association with identification information of the edged lens.

6 . A method of manufacturing a spectacle lens including a lens inspection process for performing layout inspection of an edged lens edged in accordance with a shape of a spectacle frame, and having a layout inspection mark affixed to at least one of lens surfaces,
the lens inspection process comprising the processes of: supporting the edged lens by the support unit; imaging the edged lens supported by the support unit, and performing position adjustment of the edged lens while displaying, on a monitor, a lens outline reference line indicating a position to which a visible outline of the edged lens included in an imaged image obtained by the imaging is positioned, and a layout reference mark indicating a position where the layout inspection mark is arranged, together with the imaged image; and determining quality of the layout inspection of the edged lens based on a result of the position adjustment of the edged lens.

7 . The method of manufacturing a spectacle lens according to claim 6 , wherein an inspection item of the layout inspection is positional deviation of a fitting point.

8 . The method of manufacturing a spectacle lens according to claim 6 , wherein an inspection item of the layout inspection is axial deviation of the edged lens.

9 . The lens inspection device according to claim 2 , wherein
the display control means displays a determination reference line indicating an allowable range of positional deviation of the layout inspection mark with respect to the layout reference mark on or near a display position of the layout reference mark.

10 . The lens inspection device according to claim 2 , wherein
the display control means displays a scale for visually confirming a positional deviation amount of the layout inspection mark with respect to the layout reference mark on or near a display position of the layout reference mark.

11 . The lens inspection device according to claim 3 , wherein
the display control means displays a scale for visually confirming a positional deviation amount of the layout inspection mark with respect to the layout reference mark on or near a display position of the layout reference mark.

12 . The lens inspection device according to claim 9 , wherein
the display control means displays a scale for visually confirming a positional deviation amount of the layout inspection mark with respect to the layout reference mark on or near a display position of the layout reference mark.

13 . The lens inspection device according to claim 2 , comprising:
storage means configured to store image data displayed on the monitor when position adjustment of the edged lens is performed using the lens outline reference line and the layout reference mark, in association with identification information of the edged lens.

14 . The lens inspection device according to claim 3 , comprising:
storage means configured to store image data displayed on the monitor when position adjustment of the edged lens is performed using the lens outline reference line and the layout reference mark, in association with identification information of the edged lens.

15 . The lens inspection device according to claim 4 , comprising:
storage means configured to store image data displayed on the monitor when position adjustment of the edged lens is performed using the lens outline reference line and the layout reference mark, in association with identification information of the edged lens.

16 . The lens inspection device according to claim 9 , comprising:
storage means configured to store image data displayed on the monitor when position adjustment of the edged lens is performed using the lens outline reference line and the layout reference mark, in association with identification information of the edged lens.

17 . The lens inspection device according to claim 10 , comprising:
storage means configured to store image data displayed on the monitor when position adjustment of the edged lens is performed using the lens outline reference line and the layout reference mark, in association with identification information of the edged lens.

18 . The lens inspection device according to claim 11 , comprising:
storage means configured to store image data displayed on the monitor when position adjustment of the edged lens is performed using the lens outline reference line and the layout reference mark, in association with identification information of the edged lens.

19 . The lens inspection device according to claim 12 , comprising:
storage means configured to store image data displayed on the monitor when position adjustment of the edged lens is performed using the lens outline reference line and the layout reference mark, in association with identification information of the edged lens.
