Abstract: In one embodiment, an optical pickup device includes a fixed portion 100, a movable portion 11, first and second elastic supporting members 12a and 12b, one and the other ends of which are secured to the fixed portion 100 and the movable portion 11, respectively, and an objective lens 8 secured to the movable portion 11. The objective lens 8 is arranged inside of the area that is defined between two lines that are respectively drawn from one and the other ends of the first elastic supporting member 12a perpendicularly to the first elastic supporting member 12a and outside of the area defined between the first and second elastic supporting members 12a and 12b.

Abstract: An optical disc drive for an electronic device is provided. The optical disc drive includes a rotating member, a spindle, a reading member and a controlling module. The rotating member includes a connecting member, and a first end fixed to a housing of the electronic device. The spindle is connected to a second end of the connecting member for rotating an optical disc arranged on the spindle. The reading member is fixed to the connecting member to read the optical disc. When a switch of the electronic device is actuated, a processing unit of the electronic device outputs a signal to the controlling module. The controlling module controls the rotating member to rotate. The connecting member moves the spindle and the reading member out of the housing, further controls the spindle to rotate the optical disc, and the reading member to read the optical disc.

Abstract: A disk changer apparatus includes a rotation base on which a turntable and a head are mounted. The rotation base can rotate about the rear end thereof as a fulcrum. The disk changer apparatus further includes a base supporter opposed to the top end of the rotation base when the rotation base moves to a driving position where the rotation base can drive a disk selected from a plurality of disks, a lock member movably mounted on the rotation base, and a lock control mechanism for causing the lock member to be connected to the base supporter when the rotation base moves to the driving position. The disk changer apparatus having such a structure stably supports both ends of the rotation base when the rotation base rotates to the driving position.

Abstract: The present invention relates generally to a turntable assembly for optical disks and, more particularly, to a height-variable type turntable assembly, which can adjust the height of a turntable to adjust the working distance between an object lens and an optical disk according to the type of optical disk placed on the turntable, and an optical disk device including the same. The height-variable type turntable assembly includes a turntable, a spindle motor for rotating the turntable, and a height adjustment device for supporting the spindle motor and driving the spindle motor in a vertical direction. Through such a structure, the working distance between the optical disk and the optical pick-up can be adjusted to correspond to at least three types of optical disks (e.g., CD, DVD and BD) while the DC sensitivity and tilt characteristics of the actuator of the optical pick-up is not considerably affected.

Abstract: In a disk loading apparatus according to the present invention, a clamp section is configured so as to be floatable in a direction perpendicular to the direction of disk insertion and so as to be lifted up and thereby go outside the path of disk insertion when being confronted with the inserted disk, while a traverse unit of a pickup is configured so as to position a turntable in the replay waiting position and the replay position by the rotational motion.
