Abstract: A thin blade open-close device is incorporated in a limited space. A blade open-close device includes a base located on a module board including a lens unit, a partition located opposite to the module board from the base, and a cover plate located opposite to the base from the partition. The partition and the cover plate each have an opening aligned with an optical axis of the lens unit. The blade open-close device includes a blade movable in X-direction in a blade chamber defined between the cover plate and the partition, an actuator that moves the blade between a closing position to cover the openings and an opening position to uncover the openings, and a terminal plate extending in Z-direction. The terminal plate electrically connected to the actuator includes connectors at its end adjacent to the module board to be electrically connected to contacts on the module board.

Abstract: A lens unit comprises a lens barrel, a pair of base plates, and iris blade, and a blade driving portion. The lens barrel holds a plurality of lenses, and has a first slit that extends in the circumferential direction. A pair of base plates each has an opening portion, and are stacked to structure a blade chamber, with a portion thereof protruding from the first slit, and is positioned so that the opening portions thereof are between the lenses. The iris blade is disposed in the blade chamber. A blade driving portion is secured to a portion of the pair of base plates, and drives the iris blade to open and close the opening portions in the iris blade.

Abstract: An electronic device allows the user to notice that no image capturing is being performed and increases the user comfort as well as includes a small open-close device incorporated in a limited space. A camera module is covered by a blade. This allows the user to notice that no image capturing is being performed and increases the user comfort. A base is attached to a first surface of a module board, and a cover has a first end in the longitudinal direction attached to the base and a second end in the longitudinal direction supported by the first surface of the module board. The base may not extend to the second end of the cover in the longitudinal direction and can have a shorter length (miniaturized), further miniaturizing a blade open-close device.

Abstract: A technique reduces images unintended by the user captured with an electronic device having a camera function by unauthorized access or an accidental operation performed by the user. A blade open-close device includes a blade that opens or closes a lens aperture in a camera module, an actuator that opens or closes the blade, a drive that drives the actuator, and a switch that inputs an opening signal and a closing signal into the drive. The switch includes a mechanical switch operation member that generates the opening signal and the closing signal in response to a manual operation performed by a user. The drive is independent of a drive output from the camera module.

Abstract: An imaging blade driving device includes a lens frame holding lenses, and a blade driver mounted on the lens frame including a front frame holding a front lens, a rear frame holding a rear lens and including a step with a larger diameter than the front frame, a pair of slits in a side surface of the front frame along the step, and a connector connecting the front and rear frames outside the slits. The blade driver includes a frame body, and an insert protruding from the frame body and placeable into the slits. The insert has an aperture aligned with an optical axis of the lenses and accommodating a blade. The frame body has a contact surface in contact with a surface of the rear frame perpendicular to an optical axis direction.

Abstract: A blade open-close device mountable on a module board including a lens unit includes a base including peripheral walls adjacent to the lens unit, a cover plate covering at least part of the base, and a blade movable in a blade chamber between the cover plate and a surface of the peripheral walls. A partition and the cover plate each have an opening aligned with an optical axis of the lens unit. The blade open-close device includes an actuator that moves the blade between a closing position to cover the openings and an opening position to uncover the openings. A distance from the surface of the peripheral walls to a surface of the cover plate opposite to the base along the optical axis is one fifth or less of a total of a thickness of the module board and a height of the lens unit measured along the optical axis.

Abstract: An imaging device includes an image sensor, a blade operable to switch between a closed state to at least partially block light incident on the image sensor and an open state to allow light to be incident on the image sensor, a blade driver that drives the blade, a blade controller that controls the blade driver, an authentication processor that performs authentication based on a result of imaging performed by the image sensor, and an operation detector that detects an operation. The blade controller controls the blade driver to place the blade in the open state in response to a predetermined operation detected by the operation detector and to place the blade in the closed state in response to a predetermined time passing in the open state of the blade and no success in the authentication performed by the authentication processor.

Abstract: An imaging device used in, for example, a smartphone controls a blade to avoid remaining open after unauthorized external access or a drop impact. The imaging device includes an image sensor, a blade operable to switch between a closed state in which the blade at least partially blocks light incident on the image sensor and an open state in which light is incident on the image sensor, a blade driver that drives the blade, and a blade controller that controls the blade driver. The blade controller determines whether the blade is in the closed state in a non-imaging mode in which imaging is off, and when determining that the blade is in the open state, the blade controller controls the blade driver to close the blade.
