Abstract
After a light emitting element holder is rotated, it is detected from the output value of a position adjusting light receiving element that a light beam formed by light emitted from a light emitting element is incident on a positioning target provided in a light emitting element. The light emitting element holder is duly fixed to a base member. When the incidence of the light beam on the positioning target is not detected from the output value of the position adjusting light receiving element even though the light emitting element holder is rotated, a light receiving element holder is made to slide for height adjustment and the light emitting element holder is rotated again. The adjustment of the height of the light receiving element holder and the adjustment of the rotation of the light emitting element holder are repeated until the light beam is incident on the positioning target.
