    • PROBLEM TO BE SOLVED: To provide the pattern inspection device capable of making it possible to measure the location gap of the local pattern possessing the same sensitivity as the conventional diffracted light observation, based on the images taken by a camera under the specified conditions.
      SOLUTION: It possesses the camera 20 and the image processing unit 30 equipped with the storage means 32 to memorize beforehand the feature points in the image according to the sort of the substrate to be inspected; the image feature location measuring means 33 to measure the feature points in the images as the image feature location in lower accuracy than the image resolution, in comparison with the pixel values of the surrounding two or more pixels in the location of the feature points in the image taken by the above camera according to the sort memorized in the above memory means; the generating means 34 to estimate the location considering the location of the feature point as the estimated location based on the pattern repetition period; and the error detection means 35 to detect the difference between the above measuring position and the above estimated position considered as the location error information on the above patterns. It is inspected whether the above repetition pattern is good or bad, based on the difference between the above measuring position and the above estimated position.

    • PURPOSE: To solve the trouble of consumption of sucking force in a sucking opening not covered with an article in holding a small article by dividing the vacuum chamber of a vacuum holding device into a plurality of mutually communicating vacuum chambers covered with a partitioning member with control passageways. CONSTITUTION: In a vacuum holding device effective for receiving and holding an article such as printed circuit board PCB, a vacuum chamber is divided into of a plurality of suction openings 61 innumerably bored in a surface plate body 6 and a plurality of mutually communicating vacuum chambers 21 mutually communicating through a control passageway 31. This device further comprises a plate member 5 having a valve member 51 for each control passageway 31 integrally formed with an elastic connecting part nipped between the surface plate body 6 and a space holding member 4, and the valve member 51 is regularly pressed to open the corresponding control passageway 31 to permit the application of suction force to the suction opening 61. When the suction opening 61 is not covered with the article to be held, the corresponding valve member 5 is displaced by the sucking force to block the corresponding control passageway 31.
