Claim One:
1. An appearance inspection apparatus comprising: a scanning head for scanning a board surface of a body to be inspected to capture an image thereof; and a main unit for inspecting the captured image; wherein said scanning head further comprises: at least one telecentric lens and at least a corresponding number of one-dimensional line sensors in an arrangement parallel to the image capturing direction such that each telecentric lens forms an image of reflected light reflected from said board surface and each one-dimensional sensor captures catoptrical light and that each one-dimensional sensor captures an image segment of the board surface for forming a partially overlapping portion; and wherein said main unit further comprises: an image processing unit that assembles the images captured by each of said liner sensors after calibrating pixel data in said overlapping portion and attaches the images together; and an analysis unit that inspects an image segment with reference to a given evaluation standard to determine pass or failure for each inspection item.
