Method and device for obtaining numerical coordinates of a point or a set of points |
摘要 |
A device for obtaining numerical coordinates of a point or a set of points comprises two stretched strips having a common end attached to a stylus which is placed on a point or moved over a set of points. Each of the other ends of each strip is supplied from a strip reserve consisting of pulleys connected to a restoring spring for applying tension to the strips. Variations in length of the strips are measured in discrete values by a mechanism associated with a computer for correcting the effective length of each strip.
