Then borrow, 235, 245 leak 1 ^ ^ The power source 215, 225 (4) the early element 3 moves in the clockwise or counterclockwise direction on each of the sliding tables 21~Μ, such as the third element along the board 7 边边斯贞测早湾料(四) After the detection unit 3 scans from the edge to the other end, the measurement is completed. In addition, although the four edges of the substrate 7 are long and the edge detection is borrowed, the image is borrowed. The power source 215, 225, condition 245 changes the job finder 3 in each of the riding stages 21 to 24, and the measuring unit 3 can complete the edge detection of the it 7 in a fixed time to improve the efficiency of the edge detection side of the substrate. As mentioned above, she can complete the sweep detection of the four edges of the panel at the edge inspection of the glass substrate to reduce the recording efficiency. In addition, since it is necessary to rotate the panel 8 to the scanning side of the stage, there is a disadvantage that the required turning space is also large, and the present invention provides the four ballasting units 3 to simultaneously simultaneously the substrate 7. The four edges are scanned 'and the slides 21 to 24 are only required to move linearly through the driving action of the driving elements 4, 4, and corresponding to the four edges of the substrate 7 according to the size of the substrate 7, the required space Smaller, it does improve the efficiency of detection and increase the utilization of space. Although the present invention has been disclosed using the above-described preferred embodiments, it is not a modification of the present invention by the use of the revised version of 1352197 on March 9, 100, The present invention is not limited to the spirit and scope of the present invention, and various modifications and changes to the above-described embodiments are still within the technical scope of the present invention. Therefore, the scope of the present invention is defined by the scope of the appended claims.
