  • Patent number: 8593568
    Abstract: A shape memory alloy actuation apparatus comprises a movable element supported on a support structure by a suspension system comprising a plurality of resilient flexures. A shape memory alloy actuator drives movement of the movable element on contraction. An end-stop limits the movement of the movable element in the opposite direction. Rather than using the resilient flexures of the suspension system as the sole biassing means, an additional Massing element biasses the movable element against the SMA actuator. When the moveable element is held against the end-stop, the force applied by the biassing element is greater than the force applied by the flexures of the suspension system. This reduces the design constraints, for example allowing a greater range of movement.

  • Patent number: 8203612
    Abstract: A taking lens consists of first to third lens groups. The second lens group is held in a lens frame that is coupled through an arm to a supporting shaft, and is able to rotate about the supporting shaft, to move the second lens group in a circular direction in a plane perpendicular to an optical axis of the taking lens. As a movable lens barrel retreats into a camera body, the lens frame rotates to remove the second lens group from an inserted position inserted in an optical path of the taking lens to a removed position set out of the optical path. The arm is provided with an actuator that causes the lens frame to move in a lengthwise direction of the arm. Because the movement in the circular direction includes a component that is perpendicular to the lengthwise movement of the arm, it is possible to move the lens frame and thus the second lens group in any directions in the perpendicular plane to the optical axis, in order to cancel a deviation of an optical image that result from a camera shake.

  • Patent number: 7747155
    Abstract: A zoom lens assembly for a miniature camera, such as those used in cellular telephones and other personal electronic devices, is disclosed. One or more lenses of the zoom lens assembly are moved in and/or out of the optical path of the zoom lens assembly to change the magnification of the lens. Since the magnification does not necessarily require movement of lenses along the optical path of the camera, the length of the zoom lens assembly, and consequently of the camera as well, is substantially reduced.

  • Patent number: 7706082
    Abstract: The invention relates to a zoom lens and an imaging apparatus incorporating the same. The zoom lenses comprises, in order from its object side, a positive first lens group G1, a negative second lens group G2, a positive third lens group G3, and a positive fourth lens group G4. Zooming is implemented by changing the spacing between the respective lens groups. Upon received in a lens mount, the third lens group is shifted and positioned while its optical axis is tilted at an angle of ±45° with those of other lens groups or placed substantially horizontal. At least one of lenses in the second lens group G2 or the fourth lens group G4 is configured such that a portion of that lens proximate to the third lens group being received in the lens mount is cut away. The following condition (1) is satisfied: 0.3<d×(Fnt/ft)<3.

  • Patent number: 7633693
    Abstract: A slidable lens retracting device is provided for retracting a lens system that include lens group units all positioned on a common optical axis when the lens system is in an operational state. At least one lens group unit is retracted from the on-axis position on the optical axis to an off-axis space radially off the optical axis by the slidable lens retracting device when the lens system is moved to a retracted state. The slidable lens retracting device includes slides mounted to the lens group unit and fixed support members forming inclined surfaces with which the slides are engageable. The control tracks receive the slides therein and are movable along the optical axis to bring the lens system to the retracted position to cause the slides to engage and slide along the inclined surfaces and thus moving the lens group unit to the off-axis space.

  • Patent number: 7619654
    Abstract: A taking lens consists of first to third lens groups. The second lens group is held in a lens frame that is coupled through an arm to a supporting shaft, and is able to rotate about the supporting shaft, to move the second lens group in a circular direction in a plane perpendicular to an optical axis of the taking lens. As a movable lens barrel retreats into a camera body, the lens frame rotates to remove the second lens group from an inserted position inserted in an optical path of the taking lens to a removed position set out of the optical path. The arm is provided with an actuator that causes the lens frame to move in a lengthwise direction of the arm. Because the movement in the circular direction includes a component that is perpendicular to the lengthwise movement of the arm, it is possible to move the lens frame and thus the second lens group in any directions in the perpendicular plane to the optical axis, in order to cancel a deviation of an optical image that result from a camera shake.
