A lens apparatus that can secure a necessary lens moving distance while avoiding growing in size and that is able to firmly hold a lens. The lens apparatus comprises a first lens group holding member, a second lens group holding member, an exterior cylinder disposed on an outer peripheral side of the first lens group holding member, a first cam cylinder disposed to be rotatable around an optical axis and movable in an optical axis direction corresponding to a rotation angle, a guide cylinder having a diameter fitting portion rotatably holding the first cam cylinder around the optical axis, and a second cam cylinder. The exterior cylinder does not have a cam groove or a guide groove for guiding another member, and is driven to a position at which part of the exterior cylinder is exposed to an outside corresponding to a rotation angle of the second cam cylinder.

A voice coil motor device includes a fixed component and a movable component. The movable component holds a lens. The movable component is accommodated in the fixed component. The fixed component includes a housing and a base. The housing defines a first hole and includes first side walls. The base defines a second hole. Centers of the first hole and the second hole are on an optical axis. The movable component is accommodated in the housing. The first hole receives the lens. One end of the movable component is received in the second hole of the base. The first side walls of the housing define a plurality of positioning holes, and the base includes a plurality of positioning posts. Each of the positioning posts is embedded in a corresponding one of the positioning holes.

A multi-eye interchangeable lens is disclosed. In one example, it includes a lens barrel, a movable unit, individual-eye lenses, and a light source. The movable unit is movable along an optical axis with respect to the lens barrel. The individual-eye lenses are integrally movable with the movable unit and are arranged such that emission positions of imaging lights emitted via the individual-eye lenses do not overlap with one another. The light source is configured to be movable along the optical axis integrally with the movable unit and the individual-eye lenses, and is arranged such that an emission position of an irradiation light emitted to an image sensor provided in a camera body does not overlap with the emission position of the imaging light of each of the individual-eye lenses.

A lens driving module includes a base, a frame fixedly connected to the base, and a holder configured to connect an optical lens. The holder is movable relative to the base. The lens driving module also includes a reflecting element configured to reflect light from a light incident direction to a first direction. The first direction is perpendicular to the light incident direction, and the first direction is parallel to an optical axis of the optical lens. The lens driving module further includes a first electromagnetic driving assembly configured to force the holder to move along the first direction relative to the base. The lens driving module has multiple recesses formed on the base and arranged along the first direction. The lens driving module includes multiple the rolling elements disposed on the recesses, and the holder is moved relative to the base via the rolling elements.

An optical element driving mechanism is provided, including a fixed part, a movable part, a driving assembly, and a stopping assembly. The movable part is movably disposed on the fixed part, and the movable part is connected to a first optical element. The driving assembly is at least partially disposed on the fixed part. The stopping assembly is disposed between the movable part and the fixed part. The stopping assembly limits the range of motion of the movable part relative to the fixed part.

A camera module is provided, including a holder, a base, a bottom, an image sensor, and a first biasing element. The holder holds an optical lens and is disposed on the base. The bottom supports the image sensor and connects to the base via the first biasing element. The bottom and the image sensor can be moved with respect to the base by the first biasing element.

An optical member driving mechanism is provided. The optical member driving mechanism includes a movable portion, a fixed portion, a driving assembly and a guiding assembly. The movable portion is configured to connect an optical member, and is movable relative to the fixed portion. The driving assembly is configured to drive the movable portion to move relative to the fixed portion. The guiding assembly is configured to limit the mode of movement for the movable portion relative to the fixed portion. The guiding assembly includes an intermediate element, the intermediate element contacts the fixed portion and is movable relative to the fixed portion. The guiding assembly further includes a first metallic element, the first metallic element includes metal and corresponds to the intermediate element.

Methods and apparatus for aligning a lens holder in a small-height scan engine are disclosed herein. An example method for aligning a lens holder in a small-height scan engine includes: mounting an image sensor to a circuit board; optically aligning, using one or more alignment fixtures, a lens holder holding one or more lenses or optical elements with the image sensor based upon one or more images captured by the image sensor through the lens holder; and after the lens holder and image sensor are optically aligned, physically aligning, using the one or more alignment fixtures, the lens holder with the circuit board based upon a misalignment between a surface of the lens holder and an edge of the circuit board.
