DETAILED DESCRIPTION The present invention provides an accuracy measuring method, an accuracy-measuring-program recording medium, and an electric-component mounting system which have one or more of the following technical features that are described below in respective paragraphs given parenthesized sequential numbers (1) to (25).
Any technical feature that includes another technical feature shall do so by referring, at the beginning, to the parenthesized sequential number given to the latter feature.
However, the following technical features and the appropriate combinations thereof are just examples to which the present invention is by no means limited.
In addition, in the case where one technical feature recites a plurality of items, it is not essentially required that all of those items be simultaneously employed.
That is, it is possible to select and employ only a portion (one, two, .
.
.
, but not all) of those items.
(1) According to a first feature of the present invention, there is provided a method of measuring an accuracy with which an electric-component mounting system mounts at least one electric component on a circuit substrate, the electric-component mounting system including at least one component holder for holding the at least one electric component, a substrate supporting device for supporting the circuit substrate, a first image-taking device for taking an image of at least a portion of the electric component held by the component holder, and a second image-taking device for taking an image of at least a portion of the circuit substrate supported by the substrate supporting device, at least two elements out of the component holder, the first image-taking device and the second image-taking device relating to the accuracy, the method comprising the step of measuring, with the electric-component mounting system, at least one positional error of one of the component holder, the first image-taking device and the second image-taking device relative to at least one of the others of the component holder and the first and second image-taking devices
