Abstract
An optical pick-up head module includes a base, an optical pick-up head adjusting mechanism, two guiding rods, a spring and an optical pick-up head slidably disposed on the guiding rods. The optical pick-up head adjusting mechanism includes a protrusion, a pillar and an adjusting element. The protrusion connected to the base has a sliding slot. The pillar having first and second flat surfaces is slidably disposed in the sliding slot. The first flat surface contacts an inner wall of the sliding slot. The adjusting element is screwed on the base. The spring disposed on the base pushes the pillar to contact the adjusting element by the second flat surface. When the adjusting element is rotated, the adjusting element pushes the pillar toward the base.
