An imaging unit of the disclosure includes an imaging lens including a first lens group and a second lens group that are disposed in order from object side toward image side, and an imaging device that converts an optical image formed by the imaging lens into an electric signal. The second lens group and the imaging device are rotationally moved integrally to allow the second lens group and the imaging device to be tilted with respect to an optical axis of the first lens group.

Imaging unit and imaging apparatus with rotatable lens group for optical vibration isolation

A camera module advantageous in simplifying an assembly process is provided. A camera moduleincludes a barrel unithaving a housing space S; a lens holding unitwhich holds an imaging optical system, which is housed in the housing space S, and which is supported such that the lens holding unitis movable along an optical axis of the imaging optical system; an image pickup elementwhich is disposed in the barrel unitand which picks up an object image guided by the imaging optical system; and a driving unitwhich moves the lens holding unitalong the optical axis of the imaging optical system. The barrel unitincludes an inner barrelin which the housing space S is formed and an outer barreldisposed outside the inner barrel. A retaining plateincludes a front plate portionA and two side plate portionsB. The retaining plateclamps the inner barreland the outer barrelin the optical axis direction in the state in which the front plate portionA retains a front end of the outer barreland distal ends of the two side plate portionsB retain the rear end-face wall

Camera module

A lens driver includes: an imaging lens; a housing accommodating the lens; a spring member provided between the lens and the housing and holding the lens in the housing movably in the optical axis direction; a coil moving the lens in the optical axis direction; a magnet spaced apart from the coil and moving the lens in the optical axis direction; and a yoke fixed to the magnet and having an L-shaped cross-section when taken along a plane including the optical axis, wherein the yoke is disposed in such a way that an L-shaped corner side is located on the opposite side to the position of the lens where the reaction force of the spring member resulting from the movement of the lens is maximized.

Lens driver, camera module, imaging apparatus, and camera-equipped mobile terminal

A camera module () that is advantageous in increasing the endurance and impact resistance is provided. The camera module () includes a barrel unit (), a lens holding unit (), springs (), an image pickup element (), and a driving unit (). The barrel unit () includes a front barrel () and a rear barrel (). The driving unit () moves the lens holding unit () along an optical axis of an imaging optical system (), and includes magnets () and coils (). The two magnets () are disposed on the lens holding unit () at positions having the optical axis therebetween and extend parallel to a single imaginary plane which passes through the optical axis. The coils () are respectively disposed on the barrel unit () at two positions where the coils () face the magnets ().

A lens unit includes: a lens barrel; a movable section including a movable lens and configured to be moved in an optical axis direction relative to the lens barrel; a linear actuator including a drive magnet and a drive coil and configured to move the movable section in the optical axis direction by supplying a current to the drive coil; and a pair of biasing blade springs including holding portions for holding the movable section, a plurality of spring portions biasing the movable section in the optical axis direction, and attachment portions to be attached to the lens barrel. One of the biasing blade springs is formed with two spring members through which the current is supplied to the drive coil.

Lens unit and imaging apparatus

A lens unit includes a lens barrel, an imaging system arranged therein; a movable part having a movable lens, moved in an optical axis with respect to the lens barrel; a linear actuator for moving the movable part in the optical axis direction; and a biasing plate spring having a holding section that holds the movable part, spring sections that can be resiliently deformed and bias the movable part in the optical axis direction, and attached sections that are attached to the lens barrel, the thickness direction of the plate spring coinciding with the optical axis, wherein the holding section of the biasing plate spring is formed into a circular arc; and at least a portion of the spring sections of the plate spring are formed into a shape extending in a direction substantially along the holding section on the outer peripheral side of the holding section.

The invention easily photographs a subject from plural directions collectively. When a picture photographing instruction and a moving picture photographing instruction are inputted in a master digital still cameraset as a master of photographing for a subject, the invention transmits picture photographing instruction data Dand moving picture photographing instruction data Dto slave digital still camerasA toN, subjects the subjectto picture photographing and moving picture photographing according to the picture photographing instruction data Dand the moving picture photographing instruction data Dwith the slave digital still camerasA toN, and generates and records slave picture-photographed image data Dand slave moving-picture-photographed image data Dcorresponding to a photographed image of the subject. Consequently, it is possible to photograph photographing directions different from one another collectively according to simple operation of inputting a picture photographing instruction and a moving picture photographing instruction to the master digital still camera. As a result, it is possible to easily photograph the subjectfrom plural directions collectively.

Photographing system

A lens unit includes a lens barrel having an imaging optical system arranged therein and a movable unit having a movable lens, the movable unit being movable in an optical axis direction with respect to the lens barrel. The lens barrel includes a first member and a second member adapted to be coupled together in a coupling direction. Fixing pieces are provided on the first member and the second member, respectively, and fixing means is filled between the fixing pieces when the first member and the second member are coupled together. The respective fixing pieces are provided in positions at which a force is applied in a direction in which the fixing means is compressed by the respective fixing pieces when a force is applied to the first member and the second member in a direction in which the first member is released from the second member.

Lens unit and imaging device

A magnetic head device in which magnetic head elements can follow the signal recording surface of the first or second magnetic disc . To this end, the magnetic head device includes a head unit for recording/reproducing information signals for the first or second magnetic disc , and a supporting arm having a first portion for supporting said head portion, a second portion mounted on a supporting arm holding portion and a third portion interconnecting said first and second portions and . The first to third portions to of the supporting arm are of different shapes so as to have different physical properties to follow the first or second magnetic disc under a desired condition.
