Abstract: A head device of three-dimensional modeling equipment is disclosed 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. A scanning method for a modeling plane using the same is also disclosed.
