Zusammenfassung:	PURPOSE: A skew control device of optical pickup guide shafts is provided to enable the second guide shaft to drop along a guide holder in opposite rotating direction, and to go forward along an inclined surface of a guide to control a skew, to finely control the skew while playing a disk. CONSTITUTION: A spindle motor(12) is installed on a base drive(10). An optical pickup(14) reproduces a recorded signal of a disk. The first and second guide shafts(20,30) guide a movement of the optical pickup(14). The second guide shaft(30) has an inclined surface(31) on one end thereof. A guide(40) having an inclined surface(42) corresponding to the inclined surface(31) is installed on the base drive(10). A cross-shaped groove(32) is formed on other section to rotate with other tool. A leaf spring(34) is installed under the other section. A guide holder(50) guides a spiral. A leaf spring(60) presses the second guide shaft(30).
