A separation type optical pickup device divided to a fixed optical unit and a movable optical unit. The device comprises an optical output system for emitting an optical beam arranged in the fixed unit. An optical detection system is arranged in the fixed unit. A focusing system is arranged in the movable unit for forming an optical spot on an information record medium. A deflection member is arranged in the fixed unit for deflecting and guiding the beam emitted from the optical output system to the movable unit. The member has a deflection surface which is universally rotatable about a deflection point thereof. An optical axis adjuster mechanism is arranged in the fixed unit for shifting and adjusting the optical output system in a direction perpendicular to an optical axis thereof.
