An electronic device includes a first housing, a second housing, an accommodating space and a lens module. The second housing is connected to the first housing and includes an arc edge. The accommodating space is formed between the first housing and the second housing and includes an arc area having a position corresponding to the arc edge. The lens module is located in the accommodating space, matches the shape of the accommodating space, and includes a bottom case, a side case, a top case, an internal space and a photography unit. The side case is connected to the bottom case and includes an inclined surface area which is provided in the arc area. The top case is connected to the side case and includes a top opening.

A displacement increasing mechanism has a fixing portion, first and second actuators coupled to the fixing portion, a first beam having first and second end portions and coupled to the first actuator at the first end portion, a second beam having third and fourth end portions and coupled to the second actuator at the third end portion, and a drive target member coupled to a parallel arrangement portion at which the first and second beams are arranged in parallel with each other. The first actuator is driven to pull the first beam from a second end portion side in the direction of extending the first beam, and the second actuator is driven to push the second beam form a fourth end portion side in the direction of extending the second beam.

To enable adjustment of a lens frame (lens barrel) independently, and also to enable a reduction in thickness along the optical axial direction. A blade driving device having a driving member for moving on a plane; a frame for containing the driving member; a thin blade supporting unit that protrudes to the outside, along the direction of movement of the driving member, from a portion of the thickness of the frame, and that has an opening, around the optical axis, along the direction of thickness of the frame; and a blade member that is supported on the blade supporting unit, and that is moved by the driving member, to advance into the opening; wherein the outer peripheral edge of the frame has a recessed portion at the position at which the blade supporting unit protrudes.

A camera module includes a housing having a lens module, an aperture module provided above the lens module and including blades that form incident holes having different sizes in multiple stages or successively, a moving part configured to linearly reciprocate to drive the blades, including a driving magnet facing a driving coil, a position sensor configured to sense a position of the moving part according to interaction with the driving magnet, and a controller configured to receive a signal from the position sensor and confirm or correct the position of the moving part.

The use of a blade driving device including a first plate wherein a first opening portion is formed; a blade formed so as to enable opening/closing of the first opening portion; a driving mechanism driving the blade; and a cover, wherein a second opening portion is formed so as to essentially overlap the first opening portion, and formed so as to cover the base plate and the driving mechanism portion. Because the base plate and driving mechanism portion are covered by the cover, when compared to the conventional structure, this enables the transmission, without variability, of heat in relation to the driving mechanism portion and the base plate.
