  • Apparatus for detecting cut-edge flaws in glass plates
    Patent number: 5311276
    Abstract: An apparatus for detecting flaws generated in the cut edges of cut glass plates is disclosed. The light emitted from a linear light source (11 and 21) and transmitted and reflected by a glass plate (1) is received by a one-dimensional imaging device (12 and 22), and the flaws in the cut edges of the glass plate are detected by a discriminator (13 and 24) based on the output voltage of the one-dimensional imaging device. The linear light source and the one-dimensional imaging device are disposed in such a manner that the longitudinal direction of the linear light source and the arranging direction of the imaging elements of the one-dimensional imaging device are parallel with each other, and that the longitudinal direction of the linear light source and the arranging direction of the imaging elements of the one-dimensional imaging device are oblique to the travelling direction of the glass plate on a plane parallel with the glass plate.
