Abstract
A coordinate measuring machine wherein an X carriage and a Y carriage are rendered light in weight, and the center of gravity of the Y carriage including the X carriage and a Z carriage is disposed close to a driving source, to thereby smoothen the movements of the X carriage and the Y carriage. Driving roller portions and a pair of distributing rollers are provided on the X carriage. A first and second rollers are provided at one end portion and the other end portion of an X-axis guide, so that the wire distributed by the distributing rollers can be guided around the first and second rollers. Then, a third roller is rotatably provided at one end portion of the X-axis guide, so that the wire guided around the second roller can be guided therearound. Further, the Z carriage is connected to one end portion and the other end portion of the wire guided around the driving roller portions and a balance weight is suspended from the wire guided around the first and third rollers to thereby offset the gravity of the Z carriage. With these arrangements, the wire for suspending the Z carriage is disposed along the X-axis guide, so that the Z column can be dispensed with.
