摘要： A driving device includes a holder (16) movably carried by a chassis (5) and adapted for transporting a disc cartridge the holder holds between an insertion/ejection position and a loading position, and an ejection lever (39) for ejecting the disc cartridge from the holder (16). The driving device also includes a slider (31) movable in a direction of inserting the disc cartridge into the holder (16) and in a direction of ejecting the disc cartridge from the holder. The slider causes the holder (16) to be moved to the loading position when the slider is moved in the disc cartridge inserting direction, while causing the holder (16) to be moved to the insertion/ejection position when the slider is moved in the disc cartridge ejecting direction. The driving device also includes a spring member (45) provided between the ejection lever (39) and the slider (31) for biasing the ejection lever (39) in a direction of ejecting the disc cartridge from the holder (16) and for biasing the slider (31) in the disc cartridge inserting direction.

摘要： An optical pickup includes first and second objective lenses; a first raising optical element that reflects an optical beam from a first direction within a plane substantially orthogonal to an optical axis of the first objective lens, thereby the optical beam being incident on the first objective lens; and a second raising optical element that reflects an optical beam from a second direction at an angle to the first direction within a plane substantially orthogonal to the optical axis of the second objective lens, thereby the optical beam being incident on the second objective lens. At least one lateral surface of at least one of the first and second raising optical elements is at an angle of 90 degrees or smaller to a reflection surface thereof. The lateral surface of the one raising optical element is arranged to face a lateral surface of the other raising optical element.
