description The present invention relates to: a head device of three-dimensional modeling equipment which has unidirectionally rotating polygon mirrors, can perform biaxial scanning at a high speed due to a combination of the mirrors, can easily control timing and a modeling ray irradiation position, and can enhance modeling precision; and a scanning method for a modeling plane (10) using the same. The present invention provides a head device of three-dimensional equipment which comprises: a modeling light source part (15); a first light guide part (20) which has the function of primarily reflecting modeling rays from the modeling light source part (15) and allowing the rays to be incident on a second light guide part (30); the second light guide part (30) which has the function of secondarily reflecting the modeling rays received from the first light guide part (20) and allowing the rays to be incident on a modeling plane (10); and a control part (40) which combines and controls the on-off and the output power of the modeling rays, and the operations of the first light guide part (20) and the second light guide part (30), wherein at least one of the first light guide part (20) and the second light guide part (30) comprises polygon mirrors which have a predetermined number of light reflecting surfaces at the sides thereof and unidirectionally rotate about a predetermined rotation axis.
