A technique prevents leakage of private images and/or images unintended by a user from an imaging device connected to a network, without a troublesome manual operation of opening and closing a cover. A blade operating device includes a blade that opens and closes an optical path of an imaging device connectable to a network, a blade driver that opens and closes the blade, and a controller that controls the blade driver. The controller controls the blade driver to close the blade when the imaging device is turned off.

The present invention allows reduction of the thickness of a blade driving device, and, in a mechanism in which a plurality of blade members are interlocked with one another through a lever member, drives the blade members by using sufficient thrust while keeping the operation balance of the lever member and obtaining smooth movement. A blade driving device is provided with a base member; a pair of blade members supported by the base member; a lever member the ends of which are connected to the blade members respectively, and which has, at the center thereof, a bearing part pivotally supported by a rotation shaft provided to the base member; and a linear actuator which causes the lever member to pivot about the rotation shaft, wherein the lever member includes, integrally with the bearing part, a housing part which houses a magnet of the linear actuator.

A lens module including a base, a lens, a front cover, at least a shielding plate and a gasket is provided. The lens is disposed within the base. The front cover is disposed over the base and the lens, and the base and the front cover may rotate relatively. The shielding plate is pivoted on the base and has a first guide portion. The gasket is fixed on the front cover, the shielding plate is located between the gasket and the base. The gasket has a through hole corresponding to the lens and a second guide portion coupled to the first guide portion. When the base and the front cover rotate relatively, the first guide portion is guided by the second guide portion, the shielding plate can limitedly swing to move to the through hole to cover the lens or move away from the through hole to expose the lens.

A blade open-close device includes an aperture blade having an opening on an optical axis of a lens and extending in an intersecting direction intersecting with an optical axis direction of the optical axis of the lens, a blade movable in the intersecting direction, a drive moving the blade to a closing position to cover the opening or an opening position to uncover the opening, a transmission member transmitting a driving force of the drive to the blade, a body to which the aperture blade, the blade, the drive, and the transmission member are attached, and a restrictor restricting movement of the blade in the intersecting direction. The aperture blade and the transmission member are located between the body and the blade in the optical axis direction. The body has an upper surface facing the aperture blade and the transmission member. The restrictor is located on the upper surface.

Examples that relate to sensor modules removably attachable to wearable audio devices are disclosed. In one example, a removable sensor module comprises a light sensor, a fixed magnet, and a moveable shutter. The moveable shutter comprises a bistable magnet that repels the fixed magnet to urge the shutter into either a privacy position that blocks a field of view of the light sensor or an open position that does not block the field of view of the light sensor.
