摘要： Provided is a lens barrel with which it is possible to suppress the influence of a disturbance magnetic field on a magnetic sensor. A coil that surrounds an outer periphery of a lens frame, magnetic force applying members that are disposed at a plurality of positions around the lens frame, and a magnetic sensor that detects an amount of movement of the lens frame are provided. In a plane orthogonal to an optical axis, the magnetic force applying members that are disposed on both sides adjacent to the magnetic sensor are disposed in postures in which a first angle (θ1, θ2) formed between a first straight line (L1) and a second straight line (L2) is smaller than 45°, the first straight line (L1) being a straight line passing through the magnetic sensor and the optical axis and the second straight line (L2) being a straight line orthogonal to surfaces of a first yoke and a second yoke of the magnetic force applying member that face each other.

摘要： A camera module includes a fixed base, a carrier, an elastic element, an imaging lens, a coil, a magnetic element, a connection wire and a light-blocking coating. The carrier is disposed opposite to the fixed base and has a bobbin. The elastic element is connected to the fixed base and the carrier so as to provide freedom of movement of the carrier with respect to the fixed base. The imaging lens is disposed on the carrier and has an optical axis. The coil is disposed on the carrier. The magnetic element is disposed corresponding to the coil so as to provide a driving force for moving the carrier. The connection wire is disposed on the bobbin and electrically connected to the elastic element and the coil, and the connection wire has at least part facing towards the optical axis where the light-blocking coating is disposed.

摘要： A portable information handling system camera module has a single shutter that slides in response to a single shutter mechanism to manage access for a field of view of both a visual camera and an infrared camera by sliding only between first and second positions, the first position aligning an opening of the shutter with a visual camera and a shield visual camera opening, the second position blocking the opening of the shutter and extending an end of the shutter over infrared camera. The shutter assembly is supported in a spaced relationship to the circuit board by spring biased connectors that provide power to the shutter actuator.
