An apparatus for assembling a focus lens of a laser printer scanning unit is provided to assemble the focus lens at an accurate position by moving a pair of alignment units independently from each other. An apparatus for assembling a focus lens of a laser printer scanning unit includes a base unit(100), a camera unit(200), and a pair of alignment units(300). A laser scanning unit is placed on the base unit. A focus lens is preliminarily mounted on the laser scanning unit. The camera unit is implemented in a vertical line right over the focus lens and measures an irradiation deflection of a laser beam, which passes through the focus lens. The alignment units are arranged at both sides of the base unit in a direction normal to the focus lens. When end portions of the focus lens are gripped, the alignment unit receives measured results from the camera unit and aligns the focus lens on an accurate position.
