According to an embodiment of the present invention, a linear transfer guide device for a 3D measuring apparatus comprises: a guide rail having a plurality of guide surfaces along a circumference; and a transferring unit installed on the guide rail to support an object outwardly, and to guide the object by a linear movement along the plurality of guide surfaces when transferring the object. The plurality of guide surfaces comprises a first guide surface disposed in parallel to an installation surface installed with the guide rail, and a plurality of second guide surfaces formed to be inclined to the first guide surface, and disposed to face each other against any center line perpendicularly penetrating the first guide surface. According to the present invention, three guide surfaces are formed on different positions on the outer surface of the guide rail, and three supporting units are provided on the three guide surfaces inside the transferring unit, to guide the movement of the object by rolling when the object is moved by respectively coming into contact with the three guide surfaces. As such, a surface contact between the guide rail and the transferring unit is prevented to minimize the friction force, and the device is able to stably transfer the object to a target location by evenly distributing a weight of the object by the plurality of supporting units to support the plurality of guide surfaces evenly disposed on the circumference of the guide rail, when a vertical weight or a moment weight is applied during transferring the object. |
