An imaging device that includes a shutter unit including a shutter adjusting an amount of subject light incident on an image sensor through an imaging optical system. The shutter unit being mounted on a frame. The at least three or more elastic members are disposed on an outer periphery of a contour of the shutter unit in a front view and press the shutter unit from the frame to support the shutter unit, each of the at least three or more elastic members is elastically deformed in a first direction that is a direction in which each of the at least three or more elastic members presses the shutter unit from the frame and a second direction that is a direction perpendicular to the first direction, and the first directions of the at least three or more elastic members intersect with each other at a specific spot inside the contour.

A device can include a processor; memory; a display; a bezel that defines a bezel region and a display region for the display; one or more media capture components where the one or more media capture components include a camera operatively coupled to the processor, where the camera includes an aperture disposed in the bezel region; a switch that includes an operational state for a circuit electrically coupled to the at least one of the one or more media capture components and a nonoperational state for the circuit; and a movable shutter that controls the switch, where the movable shutter includes a closed orientation that obscures a field of view of the camera and that corresponds to the nonoperational state of the switch and an open orientation that does not obscure the field of view and that corresponds to the operational state of the switch.

Because a thin blade is disposed in a space that has a thickness in the optical axial direction, which contains a coil and a magnet, when the blade is driven the blade tends to become unstable, making smooth operation of the thin blade difficult. A blade driving device has a driving member; a frame that is provided with a driving frame chamber that contains the driving member; a blade supporting unit that has an opening and that structures a blade chamber that is separate from the driving frame chamber; and a blade member that is contained in the blade chamber, and that is moved by the driving member to advance into the opening.

To achieve downsizing while securing favorable functionality by a power assist spring. Provided are a blade opening and closing device including a magnetic drive unit including a coil to which a drive current is supplied and a magnet rotated with electric conduction to the coil, a drive lever configured to be operated by the magnetic drive unit, an opening and closing blade configured to open and close an opening by an operation of the drive lever, and a power assist spring configured to provide at least the drive lever with an energizing force in an operation direction of the drive lever, in which the power assist spring is located at an opposite side of the drive lever across the magnet. Thereby, since the drive lever for operating the opening and closing blade and the power assist spring for providing the energizing force in the operation direction to the drive lever are located on the opposite side to each other across the magnet, the power assist spring and the drive lever do not interfere and the degree of freedom of the arrangement positions of the power assist spring and the drive lever becomes high, and downsizing can be achieved while securing favorable functionality by the power assist spring.

A variable aperture module includes a blade assembly including movable blades, a positioning element including positioning structures and a driving part including a rotation element. The movable blades are disposed around an optical axis to form a light passable hole with adjustable size for different hole size states and each have an inner surface to define the contour of the light passable hole in each hole size state. The positioning structures correspond to the movable blades. The rotation element is rotatable with respect to the positioning element and is configured to rotate the movable blades to adjust a size of the light passable hole. There are matte structures disposed on each inner surface. Each matte structure is single structure extending towards the optical axis, such that at least part of the contour of the light passable hole has an undulating shape at least in several hole size states.

A mobile device with variable aperture function includes two driving members, which deformation and retraction can be controlled to cause movement of a light hole of a movable aperture sheet towards a camera lens, where the amount of light entering into the camera lens is determined by the light hole of the movable aperture sheet and when the light hole in the movable aperture sheet moves away from the camera lens, the amount of light entering into the camera lens is determined by the camera lens itself, thereby varying the amount of light entering into the camera lens and eliminating the fixed amount of light due to the fixed aperture of the prior art mobile device and permitting miniaturization of the present mobile device.
