A printed-board supporting apparatus that can easily treat a height of a support surface of a support pin, is provided. The support pin is attached to a pin supporting table, and a image of the support surface of the support pin is taken by a mark-image taking device, at a first image-take position where a center of an image-take surface of the mark-image taking device is expected to coincide with a center of the support surface of the support pin. Based on the thus taken image, influences caused by positional errors of an axis line of the support pin with respect to directions perpendicular to the axis line are removed. Then, another image of the support surface is taken by the mark-image taking device, at a second image-take position where the center of the image-take surface is distant from the center of the support surface by a predetermined distance in an X-axis direction. At the second image-take position, the image of the support surface is formed, on the image-take surface, at a position corresponding to the height of the support surface. Based on the position corresponding to the height of the support surface, the height of the support surface relative to the mark-image taking device is obtained. Whether the obtained height of the support surface is appropriate is judged by judging whether an amount of error of the obtained height from a pre-set height falls within a permission range. If a negative judgment is made, it is informed to an operator.
