Abstract: An image blur correction unit includes the following elements. A holder member, holding either an imager or a lens that constitutes a part of a lens system, moves in a straight line on a plane orthogonal to the optical axis of the lens system. A movable member, attached to a frame that serves as an outermost component, supports the holder member. A guide member guides movement of the holder member relative to the frame. A driving section drives the holder member. The guide member includes a guide shaft fixed to the movable member and support portions provided for the frame, the support portions supporting the guide shaft. The movable member moves relative to the frame while being integrated with the guide shaft.

Abstract: An image blur correcting unit allows the optical axis of a lens system to coincide with the center of an imager, thus correcting an image blur. The unit includes a stationary member and a holder member. The holder member holds either one of the elements of the lens system or the imager and moves relative to the stationary member in a first direction and a second direction, the first and second directions being orthogonal to each other in a plane orthogonal to the optical axis. The unit further includes a first guide section and a second guide section for guiding the holder member in the first and second directions during movement, and a driving section moving the holder member in the first and second directions. The one of the elements of the lens system or the imager is disposed outside an area surrounded by the first and second guide sections.

Abstract: A disk drive including a turntable for holding and rotating a disk, a pickup for reading information carried by a signal and/or recording information carried by a signal to the disk by moving the pickup in a radial direction of the disk that is held and rotated by the turntable, and a feed motor for moving the pickup. A drive gear section, which engages a rack of the pickup, is integrally formed with a rotor of a sled motor. An axis of rotation of the sled motor is disposed parallel to an axis of rotation of the turntable. The disk drive makes it possible to perform seeking operations at a high speed, to reduce errors in movement of the pickup, and to achieve size reduction.
