A magnet and a coil may overlap with the upper end portion of the lens barrel in a direction perpendicular to the optical axis.

[0029] Beneficial effects

[0030] According to the embodiment, since the rotating body and the housing are arranged in a vertical direction and a rolling member is provided between the rotating body and the housing, the assembly between the rotating body and the housing can be simplified and assembly deviations can be reduced.

[0031] According to an embodiment, a recess may be formed in the extension of the rotating body, and a protrusion of the housing corresponding to the recess may be used as a stop for mechanically stopping the rotating body.

[0032] According to the embodiment, due to the recess in the extension, the rotation range of the rotating body can be increased, and the range of change of the size of the opening of the blade portion can be increased.

[0033] According to the embodiment, since the coil and the magnet face each other in a direction perpendicular to the optical axis, the size of the aperture module in the optical axis direction can be reduced.

[0034] Furthermore, according to the embodiment, since the coil and magnet overlap with the upper end and middle part of the lens barrel in the direction perpendicular to the optical axis, but do not overlap with the upper end in the direction of the optical axis, it is possible to prevent an increase in the size of the camera device in the direction perpendicular to the optical axis.

[0035] According to the embodiment, because the rotating body is in stable and close contact with the rolling member during its rotation, the size of the opening of the blade portion can be changed stably.

[0036] According to the embodiments, misalignment between the center of the aperture module opening and the center (or optical axis) of the lens unit can be prevented, and eccentricity between the center (or optical axis) of the lens unit and the center of the aperture module opening can be suppressed.

[0037] According to the embodiment, because the length of the magnetic body is greater than the length of the magnet, the rotating body can be stably supported.

[0038] In addition, according to the embodiments, spatial interference between the magnet and the coil can be avoided. The magnet can be designed to have a long length, and the attraction or holding force between the magnets can be increased. Attached Figure Description

Detailed Implementation

[0040] In the following description, embodiments of the present disclosure that can specifically achieve the above objectives will be described with reference to the accompanying drawings.

[0041] In the following description of the embodiments, it will be understood that when each component is referred to as being “above” or “below” another component, it may be directly located above or below the other component, or it may be indirectly configured such that one or more intermediate components are also present. Additionally, when a component is referred to as being “above or below”, it may include being “below the component” and “on the component”.

[0042] Furthermore, the relational terms “first,” “second,” “upper,” “lower,” and “below” are used herein only to distinguish one object or component from another, and do not necessarily require or imply any physical relationship or logical relationship or order between such objects or components. Where possible, the same reference numerals will be used throughout the accompanying drawings to refer to the same parts.

[0043] Furthermore, the terms “comprising,” “including,” and “having” described herein should be interpreted as not excluding other components, but further including such other elements, as the corresponding components may be inherent unless otherwise stated. Additionally, the term “corresponding to” described herein may encompass at least one of the meanings of “oriented toward” and “overlapping.”

[0044] In the following description, a camera device according to an embodiment and an optical instrument including the camera device will be described with reference to the accompanying drawings. For ease of description, a Cartesian coordinate system (x, y, z) will be used to describe the camera device according to the embodiment; however, the embodiment is not limited to this, and other coordinate systems may be used for description. In the various drawings, the X-axis and Y-axis may be axes extending in a direction perpendicular to the Z-axis, which is the optical axis (OA) direction.

[0045] Furthermore, the Z-axis direction, which serves as the optical axis direction, can be referred to as "any one of the first direction to the third direction," the X-axis direction can be referred to as "the other one of the first direction to the third direction," and the Y-axis direction can be referred to as "the remaining one of the first direction to the third direction." For example, the first direction can be a direction perpendicular to the image sensor's capturing area.

[0046] In addition, the X-axis (or Y-axis) can be referred to as the "first horizontal axis", the direction of the X-axis (or Y-axis) can be referred to as the "first horizontal direction", the Y-axis (or X-axis) can be referred to as the "second horizontal axis", and the direction of the Y-axis (or X-axis) can be referred to as the "second horizontal direction".

[0047] For example, the optical axis direction can be the direction of the optical axis itself or a direction parallel to the optical axis. Alternatively, for example, the optical axis can be the optical axis of a lens mounted to the lens barrel. Or, for example, the optical axis can be an axis perpendicular to the imaging area of ​​the image sensor and passing through the center of the imaging area. Additionally, in the following text, "terminal" can alternatively be referred to as a pad, electrode, or conductive layer.

[0048] Additionally, in an embodiment, when two components are joined together by the engagement between a protrusion and a hole, one of the components may be the engagement protrusion (or engagement hole), and the remaining component may be the corresponding engagement hole (or engagement protrusion).

[0049] The camera device according to the embodiment can perform image stabilization and autofocus functions.

[0050] The hand shake compensation function can be a function that moves the lens in a direction perpendicular to the optical axis or tilts the lens relative to the optical axis to eliminate vibration (or movement) caused by the user's hand shaking.

[0051] Additionally, the autofocus function can be a function that automatically focuses on the object by moving the lens along the optical axis according to the distance to the object, thereby enabling the image sensor to obtain a clear image of the object. In the following text, "camera device" may be alternatively referred to as "camera," "actuator," "camera module," "image capturing device," or "shooting device."

Figure 13c yes Figure 13b A cross-sectional view of the aperture module 100 and lens module 400.

[0053] Reference Figures 1 to 13cThe aperture module 100 can adjust or change the amount of incident light, especially the amount of light incident on the camera device 200 (see reference). Figure 17 For example, the aperture module 100 can be positioned above the lens module 400 of the camera device 200.

[0054] The aperture module 100 may include blades 150 to adjust the amount of incident light. For example, the blades 150 may be movable and may form an entrance aperture (or opening), the size of which may change in multiple stages or continuously depending on the position or displacement of the blades 150. The aperture module 100 may include entrance apertures that can be deformed in multiple stages or continuously into different sizes, and light may enter through the entrance apertures (or openings).

[0055] The aperture module 100 may include a housing 140, a blade portion 150, a rotating body 110, and a rolling member 40. The aperture module 100 may further include a drive unit for moving or rotating the rotating body 110.

[0056] The rotating body 110 can be disposed on the housing 140. The rolling member 40 can be disposed between the rotating body 110 and the housing 140, and can support the rotating body 110 relative to the housing 140. For example, the rolling member 40 can be disposed between the lower surface of the body 110A of the rotating body 110 and the lower surface of the housing 140.

[0057] At least a portion (or a first portion) of the blade portion 150 may be coupled to the housing 140, and at least one other portion (or a second portion) of the blade portion 150 may be coupled to the rotating body 110. The blade portion 150 may move or rotate as the rotating body 110 moves or rotates.

[0058] The drive unit may include a coil 120 and a magnet 130. Either the coil 120 or the magnet 130 may be disposed, coupled to, or fixed to the housing 140, and the remaining one of the coil 120 and the magnet 130 may be disposed, coupled to, or fixed to the rotating body 110. The rotating body 110 may move or rotate due to the interaction between the coil 120 and the magnet 130.

[0059] The aperture module 100 may include a cover member 300 for accommodating the rotating body 110. The cover member 300 may alternatively be referred to as a "cover". The cover member 300 may be disposed on the rotating body 110 and may be coupled to the housing 140.

[0060] Reference Figure 2a , Figure 2b and Figure 3The cover member 300 can be formed in the shape of a box with an open lower side. The cover member 300 may include an upper plate 301 and a side plate 302. The side plate 302 may be connected to the upper plate 301. For example, the side plate 302 may extend downward from the upper plate 302.

[0061] The cover member 300 may include an opening 303 formed in the upper plate 301. The opening 303 may be a hole or cavity extending through the upper plate 301 in a first direction OA. The upper plate 301 may have a circular shape. However, in other embodiments, the upper plate 301 may have a polygonal shape, such as a quadrilateral or pentagonal shape. Furthermore, the side plate 302 may have a circular shape. However, in other embodiments, the side plate 302 may have a polygonal shape, such as a quadrilateral or pentagonal shape.

[0062] The cover member 300 may include a recess 305 formed in the lower surface of the upper plate 301. The recess 305 may be a clearance recess for avoiding spatial interference with at least one of the drive shaft 51 of the rotating body 110 and the fixed shaft 71 of the housing 140, as will be described later. For example, the recess 305 may have a shape that is recessed in the lower surface of the upper plate 301.

[0063] Reference Figure 3 , Figure 12a and Figure 12b The recess 305 in the cover member 300 may include a recess 305A, which corresponds to, faces, or overlaps with the fixed shaft 71 of the housing 140 in a first direction. In addition, the recess 305 in the cover member 300 may include a recess 305B, which corresponds to, faces, or overlaps with the drive shaft 51 of the rotating body 110 in a first direction.

[0064] The recess 305A may have a shape corresponding to the fixed shaft 71, such as a circular shape. At least a portion (e.g., the upper end) of the fixed shaft 71 may be disposed in the recess 305A. For example, at least a portion (e.g., the upper end) of the fixed shaft 71 may overlap with the recess 305A in a direction perpendicular to the first direction. For example, at least a portion (e.g., the upper end) of the fixed shaft 71 may contact the recess 305A. In another embodiment, for example, at least a portion (e.g., the upper end) of the fixed shaft 71 may be spaced apart from the recess 305A.

[0065] The recess 305B can extend along the path of movement of the drive shaft 51 of the rotating body 110. This is because the lower surface of the upper plate 301 of the cover member 300 should not interfere with the movement of the drive shaft 51 of the rotating body 110. The drive shaft 51 can be curved along its path of movement, and the recess 305B can include a bent or curved shape. In another embodiment, the recess 305B can be straight. The extension length of the recess 305B in the direction of movement of the drive shaft 51 can be greater than the diameter of the drive shaft 51.

[0066] At least a portion (e.g., the upper end) of the drive shaft 51 may be disposed in the recess 305B. For example, at least a portion (e.g., the upper end) of the drive shaft 51 may overlap with the recess 305B in a direction perpendicular to the first direction. For example, at least a portion (e.g., the upper end) of the drive shaft 51 may be spaced apart from the recess 305B. For example, the upper surface of the drive shaft 51 may be spaced apart from the bottom surface of the recess 305B. The reason for this is to enable the drive shaft 51 to move.

[0067] The recess 305A may include a plurality of recesses 58A to 58F corresponding to the fixed shaft 71 of the housing 140. The plurality of recesses 58A to 58F may be provided spaced apart from each other around the opening 303 of the upper plate 301.

[0068] The recess 305B may include a plurality of recesses 59A to 59F corresponding to the drive shaft 51 of the rotating body 110. The plurality of recesses 59A to 59F may be spaced apart from each other around the opening 303 of the upper plate 301. For example, a pair of recesses (e.g., 58A and 59A) corresponding to each other may be arranged adjacent to each other. In this case, a pair of recesses (e.g., 58A and 59A) may correspond to a fixed shaft (e.g., 71A) and a drive shaft (e.g., 51A) coupled to a blade (e.g., 150A).

[0069] Reference Figure 6a , Figure 13a and Figure 13b The side plate 302 can be attached to the housing 140. The housing 140 may include at least one protrusion 45 disposed on its outer peripheral surface (or outer side surface). The protrusion 45 of the housing 140 may face or overlap the side plate 302 in a first direction, and the lower end or lower surface of the side plate 302 may be attached to the protrusion 45 of the housing 140.

[0070] The lower surface of the side panel 302 may include a first surface and a second surface, with a step between the first surface and the second surface in a first direction. For example, the second surface of the lower surface of the side panel 302 may be located at a lower position than the first surface of the lower surface of the side panel 302. The protrusion 45 of the housing 140 may include a first surface and a second surface, with a step between the first surface and the second surface in a first direction. The first surface of the protrusion 45 of the housing 140 may be located at a higher position than the second surface of the protrusion 45 of the housing 140. The first surface of the lower surface of the side panel 302 may face or overlap with the first surface of the protrusion 45 of the housing 140 in a first direction. The first surface of the lower surface of the side panel 302 may be coupled to the first surface of the protrusion 45 of the housing 140. The second surface of the lower surface of the side panel 302 may face or overlap with the second surface of the protrusion 45 of the housing 140 in a first direction. The second surface of the lower surface of the side panel 302 may be coupled to the second surface of the protrusion 45 of the housing 140. Therefore, the connection between the side plate 302 and the housing 140 can be enhanced, and the deformation or separation of the side plate 302 due to impact can be suppressed.

[0071] For example, at least one protrusion 45 may project in a direction from the inner peripheral surface of the housing 140 toward the outer peripheral surface of the housing 140. At least one protrusion 45 may face or overlap with the side plate 302 of the cover member 300 in a first direction. The protrusion 45 may be located on the upper part or upper end of the outer peripheral surface (or outer side surface) of the housing 140. For example, the protrusion 45 may be positioned closer to the upper surface of the housing 140 than the lower surface of the housing 140. The housing 140 may include a plurality of protrusions 45 spaced apart from each other in the circumferential direction of the housing 140. The protrusions 45 may be attached to the lower surface of the side plate 302.

[0072] Side panel 302 may include at least one protrusion 304A projecting from its lower surface. For example, side panel 302 may include a plurality of protrusions 304A projecting from its lower surface and spaced apart from each other. Side panel 302 may include at least one recess 304B located between the plurality of protrusions 304A. For example, the bottom surface of the recess 304B may be the lower surface of side panel 302.

[0073] The protrusion 45 of the housing 140 may include a first protrusion 45A and a second protrusion 45B, with a step between the first protrusion 45A and the second protrusion 45B in a first direction. The second protrusion 45B may be located at a lower position than the first protrusion 45A. For example, the upper surface (or "first surface") of the first protrusion 45A and the upper surface (or "second surface") of the second protrusion 45B may have a step between them in the first direction. The upper surface (or "second surface") of the second protrusion 45B may be located at a lower position than the upper surface (or "first surface") of the first protrusion 45A.

[0074] The protrusion 304A of the side plate 302 may correspond to, face, or overlap with the second protrusion 45B of the housing 140 in a first direction, and may be attached to the second protrusion 45B. In addition, the recess 305B of the side plate 302 may correspond to, face, or overlap with the first protrusion 45A of the housing 140, and may be attached to the first protrusion 45A.

[0075] Refer to Figure 4. Figure 5a and Figure 5b The blade portion 150 may be disposed in the cover member 300. The blade portion 150 may include an opening 201 that corresponds to, faces, or overlaps with the opening 303 of the cover member 300.

[0076] The blade portion 150 can adjust the size of the opening 201 through which light enters. The opening 201 of the blade portion 150 may correspond to or face the opening 205 of the support plate 160 in the first direction OA. At least a portion of the opening 201 of the blade portion 150 may overlap with the opening 205 of the support plate 160 in the first direction OA.

[0077] The blade portion 150 may include a plurality of blades 150A to 150F. As shown in FIG4, the number of blades may be six. However, in other embodiments, the number of blades may be two to five or more.

[0078] Multiple blades 150A to 150F may form an opening 201. For example, multiple blades 150A to 150F may be configured to at least partially overlap each other in a first direction, thereby forming an opening 301.

[0079] For example, a portion of the multiple blades 150A to 150F (e.g., 150A, 150C, and 150E) may be disposed on the remaining blades (e.g., 150B, 150D, and 150F) of the multiple blades 150A to 150F. For example, the multiple blades 150A to 150F may be disposed around a centerline. Specifically, the multiple blades 150A to 150F may be disposed around a centerline.

[0080] In this case, the centerline can be a straight line parallel to the optical axis. Alternatively, the centerline can be parallel to the optical axis and pass through the center 101 of the opening (see reference). Figure 12d The opening can be a straight line of the cover member 300, an opening of the blade part 150, an opening of the support plate 160, an opening of the rotating body 110, or an opening of the shell 140.

[0081] Any blade (e.g., 150A) can be configured to overlap with another adjacent or neighboring blade (e.g., 150B or 150D) in a first direction.

[0082] For example, multiple blades 150A to 150F can be arranged alternately upwards or downwards in a clockwise or counterclockwise direction. In another embodiment, multiple blades 150A to 150F can be stacked sequentially upwards or downwards in a clockwise or counterclockwise direction.

[0083] For example, at least a portion of the inner circumferential surface of each of blades 150A to 150F may include a bent or curved portion. For example, the inner circumferential surface of each of blades 150A to 150F may include a curved or recessed portion. For example, the curved or recessed portion of each of blades 150A to 150F may be configured such that its circular portion faces the optical axis. When viewed from above or in the first direction, the shape of opening 301 may include at least one of a circle, an ellipse, or a polygon (e.g., a triangle, a quadrilateral, a pentagon, or a hexagon).

[0084] At least a portion of the blade portion 150 may be coupled to the housing 140, and at least one other portion of the blade portion 150 may be coupled to the rotating body 110.

[0085] For example, the blade portion 150 may include a first portion coupled to the housing 140 and a second portion linked to the rotating body 110. For example, the blade portion 150 may rotate about its first portion, and the second portion of the blade portion 150 may move or rotate in linkage with the rotating body 110.

[0086] The blade portion 150 may include a hole 41 for engaging with a fixing shaft 71 of the housing 140. For example, the fixing shaft 71 of the housing 140 may be fitted or inserted into the hole 41 in the blade portion 150, so that the blade portion 150 is rotatable.

[0087] The blade portion 150 may include a hole 3 for engaging with a drive shaft 51 of the rotating body 110. For example, the drive shaft 71 of the rotating body 110 may be fitted or inserted into the hole 3 in the blade portion 150, enabling the blade portion 150 to rotate and move.

[0088] With the fixed shaft 71 fitted into the hole 41 in the blade portion 150, the blade portion 150 can rotate only about the fixed shaft 71. The hole 3 in the blade portion 150 can extend in one direction, allowing the drive shaft 51 to move while the drive shaft 51 is fitted into the hole 3 in the blade portion 150. For example, the hole 3 can extend in a direction intersecting the direction of rotation of the blade portion 150 about the fixed shaft 71.

[0089] The hole 3 in the blade portion 150 can be formed to correspond to the path along which the drive shaft 51 of the rotating body 110 moves. For example, the hole 3 in the blade portion 150 can extend to guide the drive shaft 51 of the rotating body 110 along its path of movement. For example, the hole 3 in the blade portion 150 can extend or be formed to be inclined in the rotational direction of the rotating body 110.

[0090] For example, blades 150A to 150F may each include holes 41A to 41F for engaging with the fixed shaft 71 and holes 3A to 3F for engaging with the drive shaft 51.

[0091] The hole 3 in the blade section 150 can be alternatively referred to as "drive shaft hole", "connection hole", "guide hole", "moving shaft hole" or "first hole (or second hole)". The hole 41 in the blade section 150 can be alternatively referred to as "rotation shaft hole", "connection hole", "fixed shaft hole" or "second hole (or first hole)".

[0092] In the aperture module 100, the "moving part (or rotating part)" can be a component or part that moves or rotates relative to the fixed part. In the aperture module 100, the "fixed part" can be a component or part that does not move or rotate with the moving part of the aperture module 100. In the aperture module 100, the "fixed part" can be a component or part that remains in a fixed state when the moving part moves or the blade part 150 is driven. The fixed part can alternatively be referred to as a "fixed body".

[0093] For example, in aperture module 100, the "moving part (or rotating part)" may include a rotating body 110 and a blade portion 150. Additionally, for example, in aperture module 100, the "moving part (or rotating part)" may include a component (e.g., a magnet 130) attached to the rotating body 110. For example, in aperture module 100, the "moving part (or rotating part)" may include a drive shaft 51. Additionally, for example, in aperture module 100, the "moving part (or rotating part)" may include a support plate 160.

[0094] In the aperture module 100, the fixing portion may include at least one of a housing 140 and a cover member 300. In the aperture module 100, the fixing portion may include components coupled to the housing 140 or the cover member 300. For example, in the aperture module 100, the fixing portion may include at least one of a circuit board 190 and a coil 120. For example, in the aperture module 100, the fixing portion may further include components coupled to the circuit board 190 (e.g., position sensor 170, capacitor 195, magnets 95 and 86, and reinforcing member 70).

[0095] Each of the plurality of blades 150A to 150F may be movable. Alternatively, the plurality of blades 150A to 150F may be movable or rotatable within a preset range. The size (e.g., diameter) of the opening 201 may vary due to the movement or rotation of the plurality of blades 150A to 150F. The opening 201 may alternatively be referred to as a “cavity,” “inlet,” or “aperture.” The movement of the blades 150A to 150F can be controlled such that the opening 201 is implemented in different sizes.

[0096] The rotating body 110 may be disposed in the cover member 300. The rotating body 110 may be disposed below the blade portion 150. The rotating body 110 may be rotatable. The rotating body 110 may be connected to the blade portion 150, and the opening 201 of the blade portion 150 may change size due to the rotation of the rotating body 110.

[0097] The rotating body 110 may include an opening 401, which corresponds to or faces the opening 201 of the blade portion 150, the opening 303 of the cover member 300, or the opening 205 of the support plate 160 in a first direction. The opening 401 may be a through hole or cavity penetrating the rotating body 110 in the first direction.

[0098] The rotating body 110 may alternatively be referred to as "rotor", "drive body", "drive plate", "rotating plate", "rotating frame", "moving plate", "moving body", "rotating ring", "drive ring" or "drive frame".

[0099] The size (e.g., area or diameter) of the opening 401 of the rotating body 110 can be larger than the size of the opening 201 of the blade portion 150. In this case, the size of the opening 201 of the blade portion 150 can be the maximum size (maximum area or maximum diameter). In another embodiment, the size (e.g., area or diameter) of the opening 401 of the rotating body 110 can be equal to the size of the opening 201 of the blade portion 150.

[0100] Additionally, the size (e.g., area or diameter) of the opening 401 of the rotating body 110 may be larger than the size of the opening 205 of the support plate 160. In another embodiment, the size (e.g., area or diameter) of the opening 401 of the rotating body 110 may be equal to the size of the opening 205 of the support plate 160.

[0101] For example, the rotating body 110 may include a ring shape for easy rotation. The rotating body 110 may include a body 110A and at least one extension 110B extending from the body 110A. For example, at least a portion of the extension 110B may be disposed in the housing 140.

[0102] For example, extension 110B may extend downward from or protrude from body 110A. Extension 110B may alternatively be referred to as a "protrusion" or a "receiving portion". Opening 401 may be formed in body 110A. Body 110A may include an annular shape. Extension 110 may accommodate magnet 130.

[0103] For example, the rotating body 110 may include a first extension 110B1 and a second extension 110B2, a first magnet unit 130A disposed in or combined with the first extension 110B1, and a second magnet unit 130B disposed in or combined with the second extension 110B2.

[0104] The rotating body 110 may include a receiving portion 24A for accommodating the magnet 130. For example, the receiving portion 24A of the rotating body 110 may be a "recess" or a "receiving recess". For example, the receiving portion 24A may be disposed or formed in an extension 110B of the rotating body 110. For example, the number of extensions 110B may be equal to the number of magnet units of the magnet 130.

[0105] For example, the rotating body 110 may include two extensions 110B1 and 110B2 located on opposite sides of the body 110A relative to the opening 401. The two extensions 110B1 and 110B2 may be configured to face each other in a second direction perpendicular to the first direction.

[0106] The receiving portion 24A may be formed in each of the extensions 110B1 and 110B2. The lower side of the receiving portion 24A may be open. The surface of the receiving portion 24A facing the coil 120 may be open. The shape of the receiving portion 24A may correspond to or be consistent with the shape of the magnet units 130A and 130B. For example, the receiving portion 24A may have a bent or curved shape corresponding to the bent or curved shape of the magnet units 130A and 130B.

[0107] For example, the surfaces of magnet units 130A and 130B that face the side surface of the receiving portion 24A may be curved surfaces, and the side surface of the receiving portion 24A may be the same as or consistent with the curved surfaces of magnet units 130A and 130B.

[0108] The magnet 130 can be disposed in the receiving portion 24A. Each of the magnet units 130A and 130B of the magnet 130 can be disposed in the receiving portion 24A of the corresponding extension of the two extensions 110B1 and 110B2.

[0109] The magnet 130 can be bonded to the receiving portion 24A using an adhesive. An injection groove 19A facilitating adhesive injection can be formed in the lower portion or lower end of each of the extensions 110B1 and 110B2. Additionally, a guide groove 18A facilitating adhesive diffusion can be formed in at least one of the side surface and bottom surface of the receiving portion 24A. For example, the guide groove 18A can be connected to or communicate with the injection groove 19A.

[0110] The rotating body 110 may include a drive shaft 51 for rotating or moving the blade portion 150. The drive shaft 51 may be connected to or linked with the blade portion 150.

[0111] The drive shaft 51 may alternatively be referred to as a "moving shaft", "column", "protrusion" or "connecting shaft". For example, the drive shaft 51 may have a cylindrical shape or a rod shape.

[0112] The rotating body 110 may include a plurality of drive shafts 51A to 51D corresponding to a plurality of blades 150A to 150F. For example, the number of drive shafts 51 may be equal to the number of blades. The plurality of drive shafts 51A to 51D may be arranged to be spaced apart from each other.

[0113] The drive shaft 51 may protrude or extend from the body 110A of the rotating body 110. For example, the drive shaft 51 may protrude or extend from the body 110A toward the blade portion 150.

[0114] The drive shaft 51 can be integrally formed with the body 110A. In another embodiment, the drive shaft 51 can have a structure that is coupled to the body 110A.

[0115] For example, one end of the drive shaft 51 can be inserted into or fitted into hole 3 (or drive shaft hole) of each of blades 150A to 150F. For example, one end of each of the plurality of drive shafts 51A to 51F can be inserted into or fitted into a corresponding hole of holes 3A to 3D in blades 150A to 150F.

[0116] The aperture module 100 may include a support plate 160 disposed between the blade portion 150 and the rotating body 110. The support plate 160 may be used to support at least a portion of the blade portion 150. For example, the support plate 160 may support at least one blade among blades 150A to 150F. The support plate 160 may alternatively be referred to as a "base plate", "support plate", or "spacer".

[0117] The support plate 160 may have a circular opening 205. The opening 205 may be a through hole. Depending on the position of the blades 150A to 150F, the opening 201 of the blade portion 150 may have a polygonal or circular shape. The support plate 160 may be used to make the opening of the aperture module 100 that receives light incident on it from the outside circular.

[0118] The support plate 160 may include clearance portions 161A to 161C and 162A to 162C to avoid spatial interference with the drive shaft 51 of the rotating body 110. For example, the support plate 160 may include a plurality of clearance portions 161A to 161C and 162A to 162C corresponding to a plurality of drive shafts 51. The clearance portions may be recesses in the outer surface of the support plate or through holes. For example, the clearance portions 161A to 161C of the support plate 160 may be through holes. The clearance portions 162A to 162C of the support plate 160 may be recesses.

[0119] The rotating body 110 may include a mounting portion 31A in which at least a portion of the support plate 160 is disposed or mounted. For example, the mounting portion 31A may be provided on the upper surface of the body 110A. The mounting portion 31A may be a recess in the upper surface of the body 110A. At least a portion of the support plate 160 may be bonded to the rotating body 110 by an adhesive. Adhesive receiving grooves 31B and 31C for receiving adhesive may be formed in the mounting portion 31A. For example, the adhesive receiving groove 31C may be formed around the drive shaft 51.

[0120] Reference Figure 4b The rotating body 110 may include a first surface 5A (or "first region"), a second surface 5B (or "second region"), and a third surface 5C (or "third region") having a step therebetween in a first direction. The second surface 5B may be located at a higher position than the first surface 5A. The third surface 5C may be located at a higher position than the second surface 5B. For example, the upper surface of the rotating body 110 may include a first surface 5A (or "first region"), a second surface 5B (or "second region"), and a third surface 5C (or "third region") having a step therebetween in a first direction.

[0121] For example, the first surface 5A may be the bottom surface of the mounting portion 31A. A support plate 160 may be disposed on the first surface 5A of the rotating body 110. For example, the support plate 160 may be bonded to the first surface 5A of the rotating body 110 by an adhesive. Adhesive receiving grooves 31B and 31C may be formed in the first surface 5A of the rotating body 110. For example, the support plate 160 may include protrusions 163 disposed on the first surface of the rotating body 110. For example, the support plate 160 may include a plurality of protrusions 163A to 163F spaced apart from each other. At least a portion of the clearance portions 161A to 161C and 162A to 162C of the support plate 160 may be formed in the protrusions. For example, the clearance portions 161A to 161C may penetrate at least a portion of the protrusions 163A, 163C, and 163E of the support plate 160. Alternatively, for example, the clearance portions 161A to 161C may be formed adjacent to or adjacent to the protrusions 163B, 163D and 163F of the support plate 160.

[0122] For example, the thickness of the support plate 160 can be less than or equal to the depth of the mounting portion 31A. For example, the depth of the mounting portion 31A can be the distance from the first surface 5A to the second surface 5B. The first surface 5A can be adjacent to or abut against the opening 401. Alternatively, the first surface 5A can be configured to be adjacent to or abut against the inner circumferential surface of the rotating body 110. For example, the second surface 5B can be located outside the first surface 5A. Additionally, the third surface 5C can be located outside the first surface 5A.

[0123] For example, multiple second surfaces 5B (or "second regions") may be provided. Multiple third surfaces 5C (or "third regions") may be provided. For example, the second surfaces 5B (or "second regions") may be spaced apart from each other in a clockwise (or counterclockwise) direction or in a rotational direction about the optical axis. For example, the third surfaces 5C (or "third regions") may be spaced apart from each other in a clockwise (or counterclockwise) direction or in a rotational direction about the optical axis.

[0124] For example, the third surface 5C (or third region) of the rotating body 110 can be located between two adjacent second surfaces 5B (or second regions). For example, the first surface 5A, the second surface 5B, and the third surface 5C can be arranged sequentially in a clockwise direction or in a rotational direction about the optical axis. The first surface 5A, the second surface 5B, and the third surface 5C can be arranged alternately in a clockwise direction or in a rotational direction about the optical axis.

[0125] A portion of the blades 150B, 150D, and 150F may be disposed on the second surface 5B. For example, at least a portion of the blades 150B, 150D, and 150F may be in contact with the second surface 5B. For example, the second surface 5B may be configured to correspond to, face, or overlap with at least a portion of the blades 150B, 150D, and 150F in a first direction.

[0126] Other portions of the blades 150A, 150C, and 150E may be disposed on the third surface 5C. For example, at least a portion of the blades 150A, 150C, and 150E may be in contact with the third surface 5C. For example, the third surface 5C may correspond to, face, or overlap with at least a portion of the blades 150A, 150C, and 150E in a first direction. Thus, because the support plate 160, blades 150B, 150D, and 150F, and other blades 150A, 150B, and 150E are disposed on the first surface 5A, second surface 5B, and third surface 5C, which have steps therebetween, spatial interference can be avoided, and the movement or rotation of the blades 150A to 150F can be facilitated.

[0127] The rotating body 110 may include a support 47 for supporting at least a portion of the rolling member 40. The support 47 may project downward from the body 110A of the rotating body 110. The support 47 may also project toward the housing 140 from the body 110A of the rotating body 110. The support 47 may alternatively be referred to as a protrusion or projection.

[0128] For example, the support portion 47 may protrude from the lower surface 110C of the rotating body 110. The support portion 47 may be located further inward relative to the optical axis than the outer surface or outer peripheral surface of the rotating body 110. For example, the support portion 47 may be closer to the inner peripheral surface (or inner side surface) of the rotating body 110 than the outer surface (or outer peripheral surface) of the rotating body 110. This is so that the support portion 47 can be adjacent to or adjacent to the rolling member 40.

[0129] The rotating body 110 may include a plurality of support portions 47A to 47D corresponding to the spherical members B1 to B4. At least a portion of the support portion 47 may face or overlap with at least a portion of the rolling member 40 in a direction perpendicular to the first direction. At least a portion of the rolling member 40 may contact the support portion 47 of the rotating body 110.

[0130] The housing 140 may be located below the body 110A of the rotating body 110 and may accommodate at least a portion of the rotating body 110. For example, the rotating body 110 and the housing 140 may be formed by injection molding using an injection mold. For example, the rotating body 110 and the housing 140 may be made of an injection-moldable material, such as plastic or resin.

[0131] Reference Figures 6a to 8d For example, the housing 140 may include an internal space capable of accommodating at least a portion of the extensions 110B1 and 110B2 of the rotating body 110.

[0132] Additionally, the housing 140 may accommodate at least a portion of the lens module 400 (see reference). Figure 13c For example, the first portion 510 and the third portion 530 of the lens module 400 may be at least partially disposed in the housing 140.

[0133] For example, housing 140 may include opening 501. Opening 501 may be a through hole or cavity extending through housing 140 in a first direction. For example, housing 140 may have a cylindrical shape.

[0134] Reference Figure 5b , Figure 6a and Figure 10a The upper surface of the housing 140 may face or overlap with the lower surface of the rotating body 110 in the first direction.

[0135] The lower portion or lower surface of the rotating body 110 may include a first surface 110C (or "first region") and a second surface 8A (or "second region") having a step with the first surface 110C (or "first region") in a first direction. When viewed from below, the second surface 8A (or "second region") may be located at a higher position than the first surface 110C (or "first region"). For example, the first surface 110C (or "first region") may be a portion that protrudes from the second surface 8A (or "second region").

[0136] The first surface 110C (or "first region") of the rotating body 110 can be configured as multiple. The second surface 8A (or "second region") of the rotating body 110 can be configured as multiple.

[0137] For example, the first surface 110C (or "first region") of the rotating body 110 may be spaced apart from each other in a clockwise (or counterclockwise) direction or in a rotational direction about the optical axis. For example, the second surface 8A (or "second region") of the rotating body 110 may be spaced apart from each other in a clockwise (or counterclockwise) direction or in a rotational direction about the optical axis.

[0138] The upper portion or upper surface of the housing 140 may include a first surface 14A (or "first region") and a second surface 14B (or "second region"), with a step between the first surface 14A and the second surface 14B in a first direction. The second surface 14B (or "second region") may be located at a lower position than the first surface 14A (or "first region").

[0139] The first surface 14A (or “first region”) of the housing 140 may face or overlap with the second surface 8A (or “second region”) of the rotating body 110 in a first direction. The first surface 110C (or “first region”) of the rotating body 110 may face or overlap with the second surface 14B (or “second region”) of the housing 140 in a first direction.

[0140] For example, the first region 14A of the housing 140 may protrude from the second region 14B. For example, the first region 14A of the housing 140 may protrude upward from the second region 14B.

[0141] The housing 140 may have multiple first surfaces 14A (or "first regions"). The housing 140 may have multiple second surfaces 14B (or "second regions").

[0142] For example, the first surface 14A (or "first region") may be spaced apart from each other in a clockwise (or counterclockwise) direction or in a rotational direction about the optical axis. For example, the second surface 14B (or "second region") may be spaced apart from each other in a clockwise (or counterclockwise) direction or in a rotational direction about the optical axis. For example, the housing 140 may have multiple third surfaces 14C (or "third regions").

[0143] A first surface 14A (or “first region”) of the housing 140 may be located between two adjacent second surfaces 14B (or “second regions”). A second surface 14B (or “second region”) of the housing 140 may be located between two adjacent first surfaces 14A (or “first regions”).

[0144] The first surface 14A (or “first region”) and the second surface 14B (or “second region”) of the housing 140 may be alternately arranged once or multiple times in a clockwise direction or in a rotational direction about the optical axis.

[0145] The fixing shaft 71 of the housing 140 may be disposed on the first surface 14A (or "first region") of the housing 140. Alternatively, the fixing shaft 71 may protrude from the first surface 14A (or "first region") of the housing 140.

[0146] The rotating body 110 may include a clearance portion 61 to avoid spatial interference with the fixed axis 71. The clearance portion 61 may be provided or formed on a second surface (or "second region") of the rotating body 110. Figure 5bAs shown, the clearance portion 61 may have the form of a through hole penetrating the body 110A in a first direction. In another embodiment, the clearance portion 61 may have the form of a recess formed in the body 110A or a clearance recess recessed in a portion of the body 110A. Alternatively, the clearance portion 61 may be formed by chamfering a portion of the body 110A. The clearance portion 61 may overlap with the fixed shaft 71 in the first direction.

[0147] For example, multiple clearance portions 61 can be provided. These clearance portions 61A to 61F can be spaced apart from each other in a clockwise (counterclockwise) direction, in the circumferential direction of the rotating body 110, or in the rotational direction of the rotating body 110. The length of the clearance portion 61 can be equal to or greater than the moving distance or range of the rotating body 110. In this case, the length of the clearance portion 61 can be the length of the clearance portion in the circumferential direction of the rotating body 110. Alternatively, the length of the clearance portion 61 can be the distance between the two ends of the clearance portions 61 that are arranged opposite each other in the circumferential direction or the rotational direction of the rotating body 110.

[0148] The lower surface of the rotating body 110 and the upper surface of the housing 140 can be configured to be spaced apart from each other by the rolling member 40. In addition, when the rotating body 110 rotates, the lower surface (or lower part) of the rotating body 110 and the upper surface (or upper part) of the housing 140 can have a clearance structure to avoid spatial interference between them.

[0149] For example, the lower surface of the rotating body 110 may include a clearance portion 55 corresponding to, facing, or overlapping with the first region 14A of the housing 140. For example, the clearance portion 55 may be a recess in the lower surface of the rotating body 110. For example, the clearance portion 55 may include a bottom surface 8A and a side surface 8B, the bottom surface 8A having a step with the first surface 110C of the lower surface of the rotating body 110, and the side surface 8B connecting the bottom surface 8A and the first surface 110C to each other. For example, the bottom surface 8A of the clearance portion 55 may be a "second surface" of the lower surface of the rotating body 110.

[0150] Because the first surface 14A (or "first region") of the housing 140 should not spatially interfere with the rotating body 110 within the rotation range (or driving range) of the rotating body 110, the length of the clearance portion 55 can be greater than the length of the first surface 14A (or "first region") of the housing 140. In this case, the length of the clearance portion 55 can be the length in the circumferential direction of the rotating body 110. Alternatively, the length of the clearance portion 55 can be the distance between the two ends of the clearance portions 55 that are disposed opposite to each other in the circumferential direction or the rotation direction of the rotating body 110. Alternatively, the length of the clearance portion 55 can be the length of the bottom surface 8A of the clearance portion 55.

[0151] The first surface 14A (or “first region”) of the housing 140 may be the length of the first surface of the housing 140 in the circumferential direction, or the distance between the two ends of the first surface 14A of the housing 140 that are disposed opposite to each other in the circumferential direction.

[0152] Additionally, the upper surface of the housing 140 may include a clearance portion 48 that corresponds to, faces, or overlaps with the first surface 110C of the lower surface of the rotating body 110. For example, the clearance portion 48 may be a recess in the upper surface of the housing 140. The clearance portion 48 may include a bottom surface 14B and a side surface 14E connecting the bottom surface 14B and the first surface 14A. For example, the bottom surface 14B of the clearance portion 48 may be a "second surface" of the upper surface of the housing 140.

[0153] The clearance portion 55 of the rotating body 110 may include a plurality of clearance portions 55A to 55F that correspond to, face or overlap with a plurality of first surfaces 14A of the housing 140.

[0154] The clearance portion 48 of the housing 140 may include a plurality of clearance portions 48A to 48D that correspond to, face, or overlap with the first surface 110C of the rotating body 110. The clearance portions 48A to 48D may be configured to be spaced apart from each other in a clockwise direction or in a rotational direction about the optical axis.

[0155] Because the first surface 110C of the rotating body 110 should not spatially interfere with the housing 140 within the rotation range of the rotating body 110, the length of the clearance portion 48 of the housing 140 can be greater than the length of the first surface 110C of the rotating body 110. In this case, the length of the clearance portion 48 can be the length in the circumferential direction of the housing 140, or the distance between the two ends of the clearance portions 48 that are opposite to each other in the circumferential direction of the housing 140. Alternatively, the length of the first surface 110C of the rotating body 110 can be the length of the first surface 110C in the circumferential direction of the rotating body 110, or the distance between the two ends of the first surface 110C that are opposite to each other in the circumferential or rotational direction of the rotating body 110. Alternatively, the length of the clearance portion 48 can be the length of the bottom surface of the clearance portion 48.

[0156] The housing 140 may include a fixed shaft 71 that is connected to or coupled to the blade portion 150. The fixed shaft 71 may be disposed on a surface of the housing 140 that faces the blade portion 150 (e.g., the upper surface or upper part).

[0157] The fixed shaft 71 may alternatively be referred to as a "rotation shaft", "column portion", "protrusion" or "connecting shaft". For example, the fixed shaft 71 may have a cylindrical shape or a rod shape.

[0158] For example, the fixing shaft 71 may protrude upward from the upper surface of the housing 140. For example, the fixing shaft 71 may be a protrusion or projection protruding from the upper surface or upper part of the housing 140. For example, the fixing shaft 71 may be disposed on the first surface 14A (or "first region") of the housing 140. For example, the fixing shaft 71 may protrude upward from the first surface 14A (or "first region") of the housing 140.

[0159] The fixed shaft 71 can be inserted into or fitted into the hole 41 in the blade portion 150. The fixed shaft 71 can be engaged with the hole 41 in the blade portion 150. For example, a lubricant or grease can be provided between the fixed shaft 71 and the hole 41 in the blade portion 150 to facilitate rotation.

[0160] The fixed shaft 71 may include a plurality of fixed shafts 71A to 71D corresponding to the plurality of blades 150A to 150F. For example, the number of fixed shafts 71 may be the same as the number of blades. For example, each of the fixed shafts 71A to 71F may be inserted into or fitted into a corresponding hole among the holes 41A to 41F in the blades 150A to 150F.

[0161] The fixed axes 71A to 71F can be set to be spaced apart from each other. For example, the straight lines connecting the fixed axes 71A to 71F can form a regular polygon.

[0162] The housing 140 may include an opening 141 for receiving or disposed therein the coil 120. The opening 141 may extend through a side or side surface of the housing 140. Alternatively, the opening 141 may open onto the upper surface of the housing 140. In another embodiment, the opening 141 may not open onto the upper surface of the housing 140.

[0163] For example, housing 140 may include a first opening 141A therein for receiving or arranging a first coil unit 120A and a second opening 141B therein for receiving or arranging a second coil unit 120B.

[0164] The housing 140 may include a clearance portion 79 for avoiding spatial interference with the support portion 47 of the rotating body 110. The clearance portion 79 may be a recess in the upper surface of the housing 140. For example, the clearance portion 79 may be a recess including a bottom surface 14C and a side surface 14D. The bottom surface 14C may be located at a position lower than the upper surface of the housing 140 (e.g., the first surface 14A or the second surface 14B).

[0165] The clearance portion 79 may be disposed adjacent to the inner surface 21A (or "inner peripheral surface") of the housing 140. The clearance portion 79 may include an opening that opens into the inner surface 21A of the housing 140. The clearance portion 79 may be configured to extend in the rotational direction of the rotating body 110.

[0166] When the rotating body 110 rotates, the clearance portion 79 of the rotating body 110 can be used to prevent the support portion 47 from spatially interfering with the housing 140. Because the support portion 47 should not spatially interfere with the housing 140 within the rotation range of the rotating body 110, the length of the clearance portion 79 can be greater than the length of the support portion 47 of the rotating body 110.

[0167] In this case, the length of the clearance portion 79 can be the length of the clearance portion 79 in the circumferential direction of the housing 140. Alternatively, the length of the clearance portion 79 can be the distance between the two ends of the clearance portions 79 that are disposed opposite to each other in the circumferential direction of the housing 140. Furthermore, the length of the support portion 47 can be the length of the support portion 47 in the circumferential direction of the rotating body 110. Alternatively, the length of the support portion 47 can be the distance between the two ends of the support portion 47 that are disposed opposite to each other in the circumferential direction or the rotational direction of the rotating body 110.

[0168] The support portion 47 of the rotating body 110 can overlap with the clearance portion 79 of the housing 140 in the first direction.

[0169] Reference Figure 6a and Figure 8d The housing 140 may include a receiving portion 33 for accommodating at least a portion of the rolling member 40. The receiving portion 33 may be in the form of a recess recessed in the upper surface of the housing 140. The receiving portion 33 may alternatively be referred to as a "recess" or a "guide recess". The receiving portion 33 of the housing 140 may have space allowing the extension 110B of the rotating body 110 to rotate.

[0170] For example, the receiving portion 33 may be provided or formed in the clearance portion 48 of the housing 140. For example, the receiving portion 33 may be formed in the bottom surface of the clearance portion 48.

[0171] For example, the receiving portion 33 may be a recess in the second surface 14B of the housing 140. The receiving portion 33 may include a bottom surface 22A and a side surface 22B (or "sidewall").

[0172] Reference Figure 12b The depth of the receiving portion 33 may be greater than the size (e.g., diameter) of the rolling member 40. For example, the depth of the receiving portion 33 may be the distance from the bottom surface 22A of the receiving portion 33 to the second surface 14B of the housing 140 in a first direction.

[0173] At least a portion of each of the spherical members B1 to B4 disposed in the receiving portion 33 of the housing 140 may protrude from the upper surface of the housing 140. For example, at least a portion of each of the spherical members B1 to B4 disposed in the receiving portion 33 of the housing 140 may protrude from the second surface 14B of the housing 140. Therefore, the rotating body 110 disposed on the spherical members B1 to B4 may be configured to be spaced apart from the housing 140 and may be easily moved or rotated.

[0174] The receiving portion 33 may include a plurality of receiving portions 33A to 33D corresponding to a plurality of spherical members B1 to B4. For example, when viewed from above, the receiving portion 33 or the rolling member 40 may be located between two adjacent fixed shafts of the housing 140.

[0175] Reference Figure 8d The length of the receiving portion 33 can be greater than the size (e.g., diameter) of the rolling member 40. For example, the length L1 of the receiving portion 33A can be greater than the size (e.g., diameter) of the spherical member (e.g., B1). The length L1 can be the length of the receiving portion 33 in the circumferential direction of the housing 140. Because the length L1 is greater than the diameter of the spherical member (e.g., B1), the spherical member (e.g., B1) can move or slide within the receiving portion (e.g., 33A) in the circumferential direction of the housing 140.

[0176] like Figure 8d As shown, a single spherical member (e.g., B1) may be provided in a receiving portion (e.g., 33A). However, in another embodiment, two or more spherical members may be provided in a receiving portion (e.g., 33A).

[0177] Reference Figure 4c , Figure 5b and Figure 12c The spherical member 40 can contact the bottom surface 22A and side surface 22B of the receiving portion 33 and the support portion 47 of the rotating body 110. For example, the support portion 47 of the rotating body 110 may include an outer surface 73B located between the lower surface 73A of the support portion 47 and the first surface 110C of the rotating body 110. The outer surface 73B of the support portion 47 can connect the lower surface of the support portion 47 to the first surface 110C of the rotating body 110.

[0178] Reference Figure 4cThe outer surface 73B of the support portion 47 may be a curved surface that bends in the circumferential direction of the rotating body 110. For example, the outer surface 73B of the support portion 47 may be a curved surface that protrudes from the inner surface 73C of the support portion 47 toward the outer surface 73B of the support portion 47. For example, the outer surface 73B of the support portion 47 and the receiving portion 33 of the housing 140 may be formed as concentric curved surfaces, arcs, or curves.

[0179] The outer surface 73B of the support portion 47 may overlap with the side surface 22B of the receiving portion 33 in a direction perpendicular to the optical axis or in a direction perpendicular to the first direction. The support portion 47 may face or overlap with the protrusion 34 of the housing 140 in the first direction.

[0180] The outer surface 73B of the support portion 47 may be an inclined surface relative to the lower surface 110C of the rotating body 110. The interior angle θ1 between the outer surface 73B of the support portion 47 and the lower surface 110C of the rotating body 110 may be an obtuse angle. Since the interior angle θ1 is formed as an obtuse angle, the contact area between the rotating body 110 and the rolling member 40 can be increased, thus stably supporting the rotating body 110.

[0181] For example, the interior angle θ1 between the outer surface 73B of the support portion 47 and the lower surface 110C of the rotating body 110 can be greater than 90 degrees and less than or equal to 160 degrees. Alternatively, the interior angle θ1 can be greater than 90 degrees and less than or equal to 135 degrees. Or, the interior angle θ1 can be greater than or equal to 100 degrees and less than or equal to 120 degrees. The spherical member 40 can contact the outer surface 73B of the support portion 47.

[0182] The support portion 47 of the rotating body 110 can be located further inward than the receiving portion 33 of the housing. For example, the optical axis or center 101 can be located closer to the support portion 47 of the rotating body 110 than the receiving portion 33 of the housing. The outer surface of the housing 140 can be located closer to the receiving portion 33 of the housing 140 than the support portion 47 of the rotating body 110.

[0183] Figure 9 This is a diagram showing the receiving portion 23 of the housing 140 according to another embodiment.

[0184] Reference Figure 9 The receiving portion 23 can be configured to allow the rolling member 40 to be inserted into or placed therein, and can have dimensions that prevent the rolling member 40 from moving. For example, the length L2 of the receiving portion 23 can be equal to the diameter of the rolling member 40. Figure 9 In the case of the housing 23, the rolling member 23 disposed in the housing 23 is not movable in the circumferential direction of the housing 140. Figure 9The rolling member 40 may include a plurality of spherical members B1 to B4.

[0185] The housing 140 may include a third surface 14C (or "third region") that has a step with the second surface 14B (or "second region") in a first direction. The third surface 14C (or "third region") may be located at a lower position than the second surface 14B (or "second region"). For example, when viewed from above, the third surface 14C may be located between the second surface 14B and the opening 401 of the housing 140. Alternatively, when viewed from above, the third surface 14C may be located between the second surface 14B and the inner surface 21A of the housing 140. For example, the third surface 14C may be the bottom surface of the clearance portion 79.

[0186] The housing 140 may include a fourth surface 14D that connects the second surface 14B and the third surface 14C to each other. For example, the fourth surface 14D may be a side surface of the clearance portion 79.

[0187] At least a portion of the rolling member 40 may protrude from the fourth surface 14D of the housing 140. At least a portion of the protrusion of the rolling member 40 may contact the rotating body 110. For example, at least a portion of the protrusion of the rolling member 40 may contact the support portion 47 of the rotating body 110.

[0188] The housing 140 may include a protrusion 34 projecting from the bottom surface 14C of the clearance portion 79. For example, a portion of the rolling member 40 may be located between the protrusion 34 of the housing 140 and the side surface 22B of the receiving portion 33. The protrusion 34 can be used to prevent the rolling member 40 from disengaging from the receiving portion 33 of the housing 140. In addition, lubricant or grease may be provided in the receiving portion 33 of the housing 140 to facilitate the rotation or sliding of the rolling member 40. The protrusion 34 of the housing 140 can prevent the lubricant or grease provided in the receiving portion 33 of the housing 140 from overflowing.

[0189] For example, the protrusion 34 may be disposed adjacent to or abutting the inner surface 21A of the housing 140. For example, the inner surface 21A of the housing 140 may include the outer peripheral surface of the protrusion 34. The protrusion 34 may be spaced apart from the fourth surface 14D, and the third surface 14C may be located between the protrusion 34 and the fourth surface 14D. The upper surface of the protrusion 34 may be lower than the second surface 14B. Additionally, the height of the protrusion 34 may be less than the diameter of the rolling member 40. Multiple protrusions 34 may be provided. Multiple protrusions 34A to 34D may be spaced apart from each other in a clockwise direction or in a rotational direction about the optical axis. The protrusion 34 may alternatively be referred to as a "step".

[0190] The housing 140 may include a receiving portion 35 for accommodating the extension 110B of the rotating body 110. The receiving portion 35 of the housing 140 may face the extension 110B of the rotating body 110 in a second direction perpendicular to the first direction.

[0191] The receiving portion 35 may be a recessed portion in the inner surface 21A of the housing 140. For example, the receiving portion 35 may include a first surface 17A and a second surface 17B, the first surface 17A having a step with the inner surface 21A of the housing 140 in a second direction perpendicular to the first direction, and the second surface 17B connecting the first surface 17A and the inner surface 21A of the housing 140 to each other. The first surface 17A may be located at a position further outward relative to the centerline or optical axis than the inner surface 21A of the housing 140.

[0192] An opening 141 may be provided in the receiving portion 35 of the housing 140. For example, the opening 141 may be formed in the first surface 17A of the housing 140. For example, the opening 141 may extend through the first surface 17A of the housing 140.

[0193] When the rotating body 110 rotates, the receiving portion 35 can be used to prevent the extension 110B of the rotating body 110 from spatially interfering with the housing 140. Since the extension 110B should not spatially interfere with the housing 140 within the rotation range of the rotating body 110, the length of the receiving portion 35 can be greater than the length of the extension 110B of the rotating body 110.

[0194] In this case, the length of the receiving portion 35 can be the length of the housing 140 in the circumferential direction, or the distance between the two ends of the receiving portions 35 disposed opposite to each other in the circumferential direction of the housing 140. For example, the length of the receiving portion 35 can be the length of the first surface 17A of the receiving portion 35.

[0195] Alternatively, the length of the extension 110B of the rotating body 110 can be the length of the extension 110B in the circumferential direction of the rotating body 110. Alternatively, the length of the extension 110B can be the distance between the two ends of the extension 110B that are disposed opposite to each other in the circumferential direction or the rotational direction of the rotating body 110.

[0196] The receiving portion 35 may include a first receiving portion 35A for receiving a first extension 110B1 of the rotating body 110 and a second receiving portion 35B for receiving a second extension 110B2 of the rotating body 110.

[0197] Reference Figure 5bThe extension 110B may include at least one recess 2A and 2B formed in its outer surface. The recesses 2A and 2B may alternatively be referred to as “avoidance portion”, “avoidance recess” or “recess”. For example, the recesses 2A and 2B may be recessed in the outer surface of the extension 110B.

[0198] For example, recesses 2A and 2B may be provided or formed in at least one of the two outer surfaces of the extension 110B that are disposed opposite to each other in the circumferential direction or rotational direction of the rotating body 110.

[0199] For example, recesses 2A and 2B can be provided between magnet 130 and body 110A. Recesses 2A and 2B can be located above magnet 130.

[0200] For example, the extension 110B may include a first portion 10A in which the magnet 130 is disposed and a second portion 10B located on the first portion 10A. A receiving portion 24A may be formed in the first portion 10A. The second portion 10B may connect the first portion 10A to the main body 110A.

[0201] For example, the length of the second part 10B may be less than the length of the first part 10A. In this case, the length may be the length of the first part 10A (or the second part 10B) in the circumferential direction of the rotating body 110. Alternatively, the length may be the distance between the two ends of the first part 10A (or the second part 10B) that are disposed opposite to each other in the circumferential or rotational direction of the rotating body 110. Alternatively, the length may be the length between the two ends of the first part 10A (or the second part 10B) that are disposed opposite to each other in the circumferential or rotational direction of the rotating body 110.

[0202] For example, recesses 2A and 2B may be formed in the outer surface of the second portion 10B of the extension 110B. Recesses 2A and 2B may be recessed in the outer surface of the second portion 10B of the extension 110B. For example, recesses 2A and 2B may be provided or formed in at least one of the two outer surfaces of the second portion 10B that are disposed opposite to each other in the circumferential direction or rotational direction of the rotating body 110.

[0203] The housing 140 may include a fixed shaft (e.g., 71B, 71C, 71E, and 71F) that overlaps with the receiving portions 35 (35A and 35B) in the optical axis direction. The housing 140 may include a protrusion 64 located on the receiving portions 35 (35A and 35B) to accommodate the fixed shaft (e.g., 71B, 71C, 71E, and 71F). The protrusion 64 may serve as a stop for inhibiting movement or rotation of the extension 110B of the rotating body 110. The protrusion 64 may alternatively be referred to as a "stop".

[0204] For example, the housing 140 may include a first protrusion 64A located at one end of the receiving portion 35 (35A and 35B) and a second protrusion 64B located at the other end of the receiving portion 35 (35A and 35B).

[0205] The recesses 2A and 2B of the extension 110B may correspond to or face the protrusion 64 of the housing 140. The protrusion 64 of the housing 140 may be used as a stop to stop the rotation or movement of the rotating body 110.

[0206] As the rotating body 110 rotates clockwise or counterclockwise, the protrusion 64 of the housing 140 can be inserted into the recesses 2A and 2B of the extension 110B.

[0207] For example, when the rotating body 110 rotates counterclockwise, the first protrusion 64A of the housing 140 can be used as a stop. Additionally, for example, when the rotating body 110 rotates clockwise, the second protrusion 64B of the housing 140 can be used as a stop.

[0208] The recesses 2A and 2B are formed in the extension 110B to prevent the rotation range or movement range of the rotating body 110 from being reduced due to the protrusion 64 of the housing 140. In other words, the rotation range or movement range of the rotating body 110 can be increased due to the recesses 2A and 2B.

[0209] In another embodiment, the rotating body 110 may include either the first recess 2A or the second recess 2B, and the housing 140 may include either the first protrusion 64A or the second protrusion 64B.

[0210] The housing 140 may include at least one recess 50 formed in its inner peripheral surface. Additionally, the housing 140 may further include at least one recess 51 formed in its lower surface or lower end. Due to the recesses 50 or 51, the thickness or width of the housing 140 may be reduced in the injection molding process, thus allowing for more accurate and easier injection molding.

[0211] The housing 140 may include a protrusion 43 for attachment to the circuit board 190. The protrusion 43 may protrude from the outer peripheral surface (or outer surface) of the housing 140. The protrusion 43 may be disposed adjacent to an opening 141 of the housing 140. The protrusion 43 may include a plurality of protrusions 43A to 43D spaced apart from each other.

[0212] Reference Figure 6a , Figure 7a , Figure 7b and Figure 14aThe housing 140 may include a mounting portion 57 on which the circuit board 190 is mounted or disposed. For example, the mounting portion 57 may include a protrusion or step protruding from the outer surface of the housing 140. For example, the mounting portion 57 may include a plurality of mounting portions 57A to 57D spaced apart from each other. The mounting portion 57 may be located on the lower part or underside of the outer surface of the housing 140. The mounting portion 57 may be disposed adjacent to the opening 141 of the housing 140. For example, the mounting portion 57 may have the form of a recess in the outer surface of the housing 140. The outer surface 27A of the housing 140 in which the mounting portion 57 is formed may be a flat surface. The mounting portion 57 may include a side surface 27A and a bottom surface 27B. The bottom surface 27B may be a flat surface. A protrusion 43 may be formed on the side surface 27A. In addition, a receiving portion 44 may be formed in the side surface 27A.

[0213] The housing 140 may include a receiving portion 44 formed to allow the magnetic body 86 to be disposed therein, coupled thereto, or fixed thereto. The receiving portion 44 may be a recess in the outer surface (or outer peripheral surface) of the housing 140. The receiving portion 44 may have the same or overlapping shape as the magnetic body 86. For example, at least a portion of the receiving portion 44 may be located between two protrusions 43A and 43B of the housing 140.

[0214] Reference Figure 11c , Figure 13a and Figure 13b The housing 140 may include at least one recess 49 recessed in its lower portion or lower surface. For example, the housing 140 may include a plurality of recesses 49A to 49D recessed in its lower surface. The plurality of recesses 49A to 49D may be configured to be spaced apart from each other in the circumferential direction of the housing 140.

[0215] The recesses 49A to 49D of the housing 140 may correspond to, face, or overlap with the protrusions 521 to 524 of the lens barrel 510 of the lens module 400 in the optical axis direction. The recesses 49A to 49D of the housing 140 may be engaged with the protrusions 521 to 524 of the lens barrel 510. The recesses 49A to 49D of the housing 140 and the protrusions 521 to 524 of the lens barrel 510 may serve as guides for assembling the housing 140 and the lens barrel 510, and may increase the engagement area between them, thereby enhancing the engagement force between them and suppressing the aperture module 100 from rotating or deforming due to impact.

[0216] The aperture module 100 may include a drive unit for driving the blade portion 150 or for rotating or moving the rotating body 110. The drive unit of the aperture module 100 may include a coil 120 disposed, coupled to, or fixed to the housing 140 and a magnet 130 disposed, coupled to, or fixed to the rotating body 110.

[0217] Due to the interaction between coil 120 and magnet 130, rotating body 110 can rotate or tilt within a preset range. Rotating body 110 can rotate about an optical axis or center line or tilt relative to an optical axis or center line. For example, magnet 130 can be a magnet.

[0218] The magnet 130 may include multiple magnet units 130A and 130B.

[0219] Despite Figure 4a Two magnet units are shown, but this disclosure is not limited thereto. In another embodiment, magnet 130 may include one magnet unit or may include three or more magnet units. The magnet unit may alternatively be referred to as a "magnet section". For example, the number of magnet units may be equal to the number of coil units of coil 120.

[0220] Each of magnet units 130A and 130B may include two N poles and two S poles. For example, magnet 130 may be a quadrupole magnetized magnet. For example, magnet unit 130A (or 130B) may include a first magnet portion 6A, a second magnet portion 6B, and a partition wall 6C disposed between the first magnet portion 6A and the second magnet portion 6B. The first magnet portion 6A and the second magnet portion 6B may be disposed opposite each other in the circumferential direction of the rotating body 110, and the partition wall 6C is inserted between the first magnet portion 6A and the second magnet portion 6B. The partition wall 6C may be a part that separates or isolates the first magnet portion 6A and the second magnet portion 6B from each other, and is substantially non-magnetic, thus having almost no polarity. For example, the partition wall 6C may be a non-magnetic material or air. The partition wall 6C may be referred to as a "neutral region," "neutral area," or "non-magnetic partition wall."

[0221] For example, refer to Figure 4a Each of the first magnet portion 6A and the second magnet portion 6B may include an N pole and an S pole. The first magnet portion 6A and the second magnet portion 6B may be arranged in the circumferential direction of the rotating body 110 such that their opposite poles face each other.

[0222] For example, the N pole and S pole of each of the first magnet portion 6A and the second magnet portion 6B can be configured to face each other or be separated from each other in a second direction perpendicular to the first direction. For example, the outer peripheral surface 7A of the magnet 130 (130A and 130B) may include N pole and S pole.

[0223] For example, the N pole (or S pole) of the first magnet portion 6A and the S pole (or N pole) of the second magnet portion 6B can form the outer surface of the magnet, and the S pole (or N pole) of the first magnet portion 6A and the N pole (or S pole) of the second magnet portion 6B can form the inner surface of the magnet 130.

[0224] In another embodiment, the first magnet portion and the second magnet portion of magnet unit 130A or 130B may be configured to face each other in a first direction, with a partition wall inserted between the first magnet portion and the second magnet portion.

[0225] In another embodiment, magnet 130 may include an N pole and a S pole. For example, in another embodiment, magnet 130 may be a bipolar magnet. For example, in another embodiment, the N pole and S pole of the magnet unit may face each other in a second direction perpendicular to the first direction. In yet another embodiment, the N pole and S pole of the magnet unit may face each other or be separated from each other in the first direction.

[0226] Magnet unit 130A or 130B may include a bent or curved shape. For example, when viewed from above or along the optical axis, the appearance of magnet unit 130A or 130B may include a bent shape. For example, the outer peripheral surface (or outer side surface) of magnet unit 130A or 130B may include a bent or curved shape. Additionally, the inner peripheral surface (or inner side surface) of magnet unit 130A or 130B may have a bent or curved shape.

[0227] For example, the inner peripheral surface (or inner side surface) of magnet unit 130A or 130B can be the side surface of magnet unit 130A or 130B that is opposite to or facing the optical axis, and the outer peripheral surface (or outer side surface) of magnet unit 130A or 130B can be the surface that is opposite to the inner peripheral surface (or inner side surface) of magnet unit 130A or 130B.

[0228] Magnet units 130A or 130B can be bent in a convex direction from their inner peripheral surface toward their outer peripheral surface. For example, the curvature of the outer peripheral surface (or outer side surface) of magnet units 130A or 130B can be greater than the curvature of the inner peripheral surface (or inner side surface) of magnet units 130A or 130B. One reason for this is to allow magnet units 130A or 130B to be easily disposed or placed within the cylindrical rotating body 110. Another reason is to allow magnet units 130A or 130B to be easily rotated together with the rotating body 110.

[0229] Coil 120 may be disposed, coupled to, or fixed to housing 140 in a manner corresponding to or facing magnet 130. For example, coil 120 may face or overlap magnet 130 in a direction perpendicular to the optical axis (e.g., a second direction). For example, at least a portion of coil 120 may overlap magnet 130 in a direction perpendicular to the optical axis (e.g., a second direction) within the rotational range of rotating body 110. Coil 120 may not overlap magnet 130 in a first direction (or optical axis direction).

[0230] Coil 120 may include a plurality of coil units 120A and 120B corresponding to magnet units 130A and 130B. The number of coil units in coil 120 may be equal to the number of magnet units in magnet 130 used for driving. In another embodiment, the number of coil units in coil 120 (or the number of magnet units in magnet 130) may be one. In yet another embodiment, the number of coil units in coil 120 (or the number of magnet units in magnet 130) may be three or more.

[0231] Each of coil units 120A and 120B may face or overlap with a corresponding one of magnet units 130A and 130B in a second direction perpendicular to the first direction. Each of coil units 120A and 120B may include a cavity 9A (see reference). Figure 6b ).

[0232] Each of coil units 120A and 120B may have an annular shape wound around an axis parallel to the second direction. Each of coil units 120A and 120B may be an annular coil block. For example, each of coil units 120A and 120B may include an annular body, and the body may include a cavity 9A. In another embodiment, at least one of coil units 120A and 120B may not include a cavity.

[0233] The coil unit 120 can be disposed in the opening 141 of the housing 140.

[0234] The aperture module 100 may include a circuit board 190 electrically connected to the coil 120. The circuit board 190 may be disposed within the housing 140. The circuit board 190 may be coupled to or fixed to the housing 140. For example, the circuit board 190 may be disposed on the outer peripheral surface (or outer surface) of the housing 140. For example, the circuit board 190 may be bonded to the housing 140 by adhesive.

[0235] Reference Figure 6a , Figure 7a and Figure 7b The circuit board 190 may include a first circuit board 191 on which a first coil unit 120A is disposed, a second circuit board 192 on which a second coil unit 120B is disposed, and a third circuit board 193 connecting the first circuit board 191 and the second circuit board 192 to each other. For example, the first circuit board 191 and the second circuit board 192 may be rigid substrates or flexible substrates, and the third circuit board 193 may be a flexible substrate.

[0236] The first circuit board 191 may face or overlap with the first opening 141A of the housing 140, and the second circuit board 192 may face or overlap with the second opening 141B of the housing 140. The third circuit board 193 may be located below the protrusion 45 of the housing 140 and may contact or be coupled to the protrusion 45. The protrusion 45 of the housing 140 may be used to support and guide the third circuit board 193.

[0237] The first circuit board 191 may include a first portion 191A (or "first region") and a second portion 191B (or "second region"). A first coil unit 120A is disposed on or attached to the first portion 191A, and terminals 16A and 16B (or pads) electrically connected to the first coil unit 120A are disposed on the second portion 191B. For example, one end (or starting line) S1 of the first coil unit 120A may be electrically or conductively attached to the first terminal 16A, and the other end (or terminal line) S2 of the first coil unit 120A may be electrically or conductively attached to the second terminal 16B.

[0238] End S1 and end S2 of the first coil unit 120A can be electrically connected to the first terminal 16A and the second terminal 16B by solder or conductive adhesive. The first terminal 16A and the second terminal 16B can be opened or exposed through the first opening 141A of the housing 140.

[0239] The first coil unit 120A may be disposed on or attached to the first surface of the first portion 191A of the first circuit board 191. The first surface of the first portion 191A may be the surface facing the first magnet unit 130A. End S1 and the other end S2 of the first coil unit 120A may extend from the annular body to the first terminal 16A and the second terminal 16B.

[0240] For example, the first portion 191A may include a through hole 91A located between the body of the first coil unit 120A and the first terminal 16A and the second terminal 16B. Due to the through hole 91A, spatial interference between the portion of the first coil unit 120A connecting the end S1 and the other end S2 of the first coil unit 120A and the body of the first coil unit 120A and the first portion 191A of the first circuit board 191 can be avoided.

[0241] The second part 191B may include a plurality of terminals Q1 to Q4 for external electrical connection. For example, the plurality of terminals Q1 to Q4 may be disposed on a second surface of the second part 191B. The second surface of the second part 191B may be a surface opposite to the first surface of the second part 191B. The first surface of the second part 191B may be a surface facing the outer surface (or outer peripheral surface) of the housing 140.

[0242] The first circuit board 191 may include a third portion 191C (or "third region") connected to the first portion 191A. The third portion 191C may be disposed on the opposite side of the second portion 191B relative to the first portion 191A. The third portion 191C may include at least one through hole 11A and 11B for engaging with at least one protrusion 43A and 43B of the housing 140.

[0243] The second circuit board 192 may be configured to face or overlap the first circuit board 191 in a second direction. The second circuit board 192 may include a first portion 192A (or "first region") and a second portion 192B (or "second region"). A second coil unit 120B is disposed on or coupled to the first portion 192A, and terminals 15A and 15B (or pads) electrically connected to the second coil unit 120B are disposed on the second portion 192B. For example, one end (or starting line) S3 of the second coil unit 120B may be electrically or conductively coupled to a third terminal 15A, and the other end (or terminal line) S4 of the second coil unit 120B may be electrically or conductively coupled to a fourth terminal 15B.

[0244] End S3 and the other end S4 of the second coil unit 120B can be electrically connected to the third terminal 15A and the fourth terminal 15B by solder or conductive adhesive. The third terminal 15A and the fourth terminal 15B can be opened or exposed through the second opening 141B of the housing 140.

[0245] The second coil unit 120B may be disposed on or attached to the first surface of the first portion 192A of the second circuit board 192. The first surface of the first portion 192A may be the surface facing the second magnet unit 130B. End S3 and the other end S4 of the second coil unit 120B may extend from the annular body to the third terminal 15A and the fourth terminal 15B.

[0246] For example, the first portion 192A of the second circuit board 192 may include a through hole 91B located between the body of the second coil unit 120B and the third terminal 15A and the fourth terminal 15B. Due to the through hole 91B, spatial interference between a portion of the second coil unit 120B connecting end S3 and the other end S4 of the second coil unit 120B to the body of the second coil unit 120B and the first portion 192A of the second circuit board 192 can be avoided.

[0247] The second portion 192B of the second circuit board 192 may include at least one terminal P1 and P2 for external electrical connection (see reference). Figure 11cFor example, at least one terminal R1 and R2 may be disposed on the second surface of the second portion 192B. The second surface of the second portion 192B may be a surface opposite to the first surface of the second portion 192B. The first surface of the second portion 192B may be a surface facing the outer surface (or outer peripheral surface) of the housing 140.

[0248] The second circuit board 192 may include a third portion 192C connected to the first portion 192A. The third portion 192C may be disposed on the opposite side of the second portion 192B relative to the first portion 192A. The third portion 192C may include at least one through hole 12A and 12B for engaging with at least one protrusion 43C and 43D of the housing 140.

[0249] The third circuit board 193 can interconnect the second portion 191B of the first circuit board 191 and the second portion 192B of the second circuit board 192. For example, the length of the third circuit board 193 in the first direction can be less than the length of the first circuit board 191 in the first direction. The length of the third circuit board 193 in the first direction can be less than the length of the second circuit board 192 in the first direction.

[0250] The first coil unit 120A and the second coil unit 120B can be connected in series with each other. For example, the first coil unit 120A and the second coil unit 120B can be connected in series with each other via a circuit board 190. For example, one of the first terminal 16A and the second terminal 16B of the first circuit board 191 and one of the third terminal 15A and the fourth terminal 15B of the second circuit board 192 can be electrically connected with each other via a third circuit board 193. A drive signal can be provided to the first coil unit 120A and the second coil unit 120B connected in series with each other via the circuit board 190.

[0251] In another embodiment, the first coil unit 120A and the second coil unit 120B may be connected in parallel with each other. A drive signal may be provided to the coil units 120A and 120B connected in parallel with each other. In yet another embodiment, the coil units 120A and 120B may be arranged independently rather than connected to each other, and each of the first coil unit 120A and the second coil unit 120B may be provided with a separate independent drive signal via the circuit board 190. For example, each of the first coil unit 120A and the second coil unit 120B may be driven independently in response to a separate drive signal.

[0252] If a drive signal is provided to coil 120, the rotating body 110 can rotate around the optical axis due to the electromagnetic force generated by the interaction between magnet 130 and coil 120. As the rotating body 110 rotates, the blades 150A to 150F (or the blades 150A to 150F into which the drive shaft 51 is inserted) linked to the drive shaft 51 can rotate around the fixed axis 71 of housing 140 within a preset range.

[0253] As the blades 150A to 150F rotate, the size of the opening 201 of the blade section 150 can be changed step by step or continuously.

[0254] For example, the size of the opening 201 of the blade portion 150 can be adjusted to or changed to three or more different sizes. For example, the size of the opening 201 of the blade portion 150 can be adjusted to or changed to ten or fewer different sizes. For example, the size of the opening 201 of the blade portion 150 can be adjusted to or changed to three or more but no more than seven different sizes.

[0255] For example, the levels at which the size of the opening 201 is changed can include an initial level, two or more intermediate levels, and a final level. For instance, the initial level could be the level where the opening 201 of the blade portion 150 has the largest size, the final level could be the level where the opening 201 of the blade portion 150 has the smallest size, and the two or more intermediate levels could be levels where the opening 201 of the blade portion 150 has different intermediate sizes. The intermediate sizes can be larger than the minimum size and smaller than the maximum size.

[0256] The aperture module 100 may include a position sensor 170 for detecting the displacement of the blade portion 150. The position sensor 170 may detect the magnetic field of the magnet 130. Alternatively, the position sensor 170 may detect the displacement or position of the magnet 130. Alternatively, the position sensor 170 may detect the displacement or position of the drive shaft 51. Alternatively, the position sensor 170 may detect the displacement or position of the rotating body 110.

[0257] Position sensor 170 may be disposed within housing 140. Alternatively, position sensor 170 may be coupled to or fixed to housing 140. For example, position sensor 170 may be disposed on or coupled to circuit board 190. Position sensor 170 may be electrically or conductively connected to circuit board 190. Position sensor 170 may be disposed in a first opening 141A of housing 140.

[0258] Position sensor 170 may be disposed on the first circuit board 191. For example, position sensor 170 may be disposed on a first portion 191A of the first circuit board 191. In another embodiment, position sensor 170 may be disposed on a second portion 191B or a third portion 191C of the first circuit board 191. Position sensor 170 may be disposed on a first surface of the first circuit board 191 (or the first portion 191A). Position sensor 170 may be disposed within a cavity 9A in the first coil unit 120A. Position sensor 170 may not overlap with coil 120 (or coil unit (e.g., 120A)) in a second direction. For example, position sensor 170 may overlap with cavity 9A in coil unit 120A in a second direction. In another embodiment, position sensor 170 may be located outside cavity 9A in the first coil unit 120A.

[0259] At least a portion of the position sensor 170 may face or overlap with the first magnet unit 130A in a second direction perpendicular to the first direction. The position sensor 170 can detect the first magnet unit 130A. The position sensor 170 can detect the magnetic field of the first magnet unit 130A.

[0260] The position sensor 170 may be a driver IC that includes a Hall sensor. The position sensor 170 in the form of a driver IC can send and receive data to and from the outside via data communication using a protocol (e.g., I2C communication), and can provide drive signals to the coil 120.

[0261] For example, if the position sensor 170 is a driver IC that includes a Hall sensor, the position sensor 170 may include a first terminal and a second terminal for receiving power or a drive signal, a third terminal for a clock signal, a fourth terminal for a data signal, and a fifth and a sixth terminal for supplying a drive signal to the coil 120. The first to sixth terminals of the position sensor 170 may be electrically connected to or electrically connected to the circuit board 190.

[0262] Additionally, the first to fourth terminals of the position sensor 170 can be electrically or conductively connected to terminals Q1 to Q4 of the circuit board 190. Furthermore, the fifth and sixth terminals of the position sensor 170 can supply power or drive signals to the first coil unit 120A and the second coil unit 120B, which are connected in series with each other. For example, the fifth terminal of the position sensor 170 can be electrically or conductively connected to the remaining one of the first terminal 16A and the second terminal 16B of the first circuit board 191. Additionally, the sixth terminal of the position sensor 170 can be electrically or conductively connected to the remaining one of the third terminal 15A and the fourth terminal 15B of the second circuit board 192.

[0263] In another embodiment, the position sensor 170 may be an anisotropic magnetoresistive (AMR) sensor, a giant magnetoresistive (GMR) sensor, or a tunnel magnetoresistive (TMR) sensor.

[0264] In another embodiment, the position sensor 170 may be a Hall sensor.

[0265] The position sensor 170, in the form of a Hall effect sensor, may include two input terminals from which a drive signal is applied and two output terminals from which an output signal is output. Each of the two input terminals and two output terminals of the position sensor 170 may be electrically connected to a corresponding terminal among terminals Q1 to Q4 of the circuit board 190.

[0266] A drive signal can be supplied from outside the aperture module to the two input terminals of the position sensor 170 (or "Hall sensor") via two of the terminals Q1 to Q4 of the circuit board 190. Additionally, the output signal from the two output terminals of the position sensor 170 (or "Hall sensor") can be output to the outside of the aperture module via the two remaining terminals Q1 to Q4 of the circuit board 190. Furthermore, a drive signal or power can be input from outside to the coil 120 via two other terminals P1 and P2 of the circuit board 190. The coil 120 can be electrically or conductively connected to the two terminals P1 and P2, and power or a drive signal can be supplied to the coil 120 via the two terminals P1 and P2.

[0267] In another embodiment, the aperture module 100 may further include a position sensor disposed on the second circuit board 192 and facing or overlapping the second magnet unit 130B. The description of the position sensor 170 may be applied equivalently or similarly to the additional position sensor.

[0268] The aperture module 100 may include a capacitor 195 disposed on a circuit board 190. The capacitor 195 may be disposed on a first circuit board 191 or a second circuit board 192. The capacitor 195 may be disposed on or mounted on a first surface of the circuit board 190. For example, the capacitor 195 may be disposed on a third portion 191C of the first circuit board 191. The capacitor 195 may be disposed in an opening 141A of the housing 140. The capacitor 195 may be exposed from the opening 141A of the housing 140.

[0269] The capacitor 195 may be a chip type. In this case, the chip may include a first terminal corresponding to one end of the capacitor 195 and a second terminal corresponding to the other end of the capacitor 195. The capacitor 195 may alternatively be referred to as a "capacitive element" or a "capacitor".

[0270] Capacitor 195 may be electrically connected to two terminals (e.g., B1 and B2) of circuit board 190 used to supply power (or drive signals) to position sensor 170 from the outside. Capacitor 195 may be electrically connected to the two terminals (e.g., B1 and B2) in parallel or series.

[0271] For example, one end of capacitor 195 may be electrically connected to one of two terminals (e.g., B1 and B2), and the other end of capacitor 195 may be electrically connected to the remaining terminal of the two terminals (e.g., B1 and B2). Alternatively, capacitor 195 may be electrically connected to the first and second terminals of position sensor 170, which are electrically connected to the two terminals (e.g., B1 and B2) of circuit board 190.

[0272] Because capacitor 195 is electrically connected to terminals B1 and B2 of circuit board 190, capacitor 195 can be used as a smoothing circuit to remove ripple or high-frequency components included in power supply signals GND and VDD, which are supplied to position sensor 170 from the outside, thus providing a stable and uniform power signal to position sensor 170.

[0273] The aperture module 100 may include a reinforcing member 70 disposed on at least a portion of the circuit board 190. The reinforcing member 70 can prevent the circuit board 190 from being damaged, deformed, or destroyed by impact or external force. For example, the reinforcing member 70 may contain at least one of a metallic material and an injection-molded material (e.g., plastic or resin).

[0274] The reinforcing member 70 may include at least one reinforcing member 70A and 70B disposed on the first circuit board 191 and at least one reinforcing member 70C and 70D disposed on the second circuit board 192. In another embodiment, at least one of the reinforcing members 70A to 70D may be omitted. The reinforcing member 70 may be disposed on at least one of the first portion 191A and the second portion 191B of the first circuit board 191 and the first portion 192A and the second portion 192B of the second circuit board 192.

[0275] The first reinforcing member 70A may be disposed on the first portion 191A of the first circuit board 191. The first reinforcing member 70A may be disposed on the second surface of the first portion 191A. The second surface of the first portion 191A may be a surface opposite to the first surface of the first portion 191A. At least a portion of the first reinforcing member 70A may overlap with or block the through hole 91A in the housing 140.

[0276] For example, the second reinforcing member 70B may be disposed on the third portion 191C of the first circuit board 191. The second reinforcing member 70B may be disposed on the second surface of the third portion 191C. The second surface of the third portion 191C may be a surface opposite to the first surface of the third portion 191C of the first circuit board 191. The first surface of the third portion 191C may be a surface facing or in contact with the outer peripheral surface (or outer surface) of the housing 140. The second reinforcing member 70B may include clearance recesses 71A and 71B for avoiding spatial interference with the protrusions 43A and 43B of the housing 140.

[0277] The third reinforcing member 70C may be disposed on the first portion 192A of the second circuit board 192. The third reinforcing member 70C may be disposed on the second surface of the first portion 192A of the second circuit board 192. The second surface of the first portion 192A may be a surface opposite to the first surface of the first portion 192A of the second circuit board 192. At least a portion of the third reinforcing member 70C may overlap with or block the through hole 91B in the housing 140.

[0278] The fourth reinforcing member 70D may be disposed on the third portion 192C of the second circuit board 192. The fourth reinforcing member 70D may be disposed on the second surface of the third portion 192C of the second circuit board 192. The second surface of the third portion 192C may be a surface opposite to the first surface of the third portion 192C of the second circuit board 192. The first surface of the third portion 192C of the second circuit board 192 may be a surface facing or in contact with the outer peripheral surface (or outer surface) of the housing 140. The fourth reinforcing member 70D may include a clearance recess for avoiding spatial interference with the protrusions 43C and 43D of the housing 140.

[0279] The reinforcing member 70A may face or overlap with the first coil unit 120A in the second direction, and the reinforcing member 70C may face or overlap with the second coil unit 120B in the second direction. In another embodiment, the reinforcing members 70A and 70B may be made of metallic material and may be used as a yoke to increase the electromagnetic force between the coil 120 and the magnet 130.

[0280] In another embodiment, the reinforcing member 70 may also serve as a heat dissipation member for dissipating heat generated from the circuit board 190 and components attached to the circuit board 190 (e.g., coil 120, position sensor 170, and capacitor 195). In this case, the reinforcing member 70 may alternatively be referred to as a "heat dissipation member" or "heat sink".

[0281] A rolling member 40 can be disposed between the rotating body 110 and the housing 140. The rolling member 40 can perform rolling or sliding motion between the housing 140 and the rotating body 110, thereby reducing the friction between the rotating body 110 and the housing 140. Therefore, the rotating body 110 can be easily rotated or moved, and the amount of drive current or power consumed by the rotating body 110 in rotating or moving can be reduced.

[0282] For example, at least a portion of the rolling member 40 may contact the housing 140. Additionally, for example, at least one other portion of the rolling member 40 may contact the rotating body 110.

[0283] The rolling member 40 may alternatively be referred to as a "ball," "spherical member," or "ball bearing." The rolling member 40 may be made of, for example, metal, plastic, or resin, but this disclosure is not limited thereto. The rolling member 40 may have a circular shape and may have a sufficiently large diameter to support the rotation or movement of the rotating body 110. For example, the rolling member 40 may include a plurality of spherical members B1 to B4 or a plurality of balls. (See reference...) Figure 6a The rolling member 40 includes four spherical members B1 to B4. However, in another embodiment, the number of spherical members may be two, three, or more than five. At least a portion of the rolling member 40 may be disposed in the receiving portion 33 of the housing 140.

[0284] Figure 14a This is a diagram showing the magnetic body 95 disposed in the housing 140. Figure 14b yes Figure 14a The bottom view, Figure 14c It is a bottom view of the rotating body 110, the magnet 130, the magnetic body 95 and the rolling component 40. Figure 15a This is a first perspective view of the rotating body 110, the magnet 130, and the magnetic body 95. Figure 15b This is a second perspective view of the rotating body 110, the magnet 130, and the magnetic body 95.

[0285] Reference Figures 14a to 15b The aperture module 100 may further include a magnetic element 95 disposed within the housing 140. The magnetic element 95 may be coupled to or fixed to the housing 140. For example... Figure 14a and Figure 14b As shown, the magnetic body 95 can be bonded to the housing 140 by insert injection molding.

[0286] If the magnetic body 95 is injection molded to the housing 140, at least a portion of the magnetic body 95 may be embedded within the housing 140. For example, an end (or distal end) of the magnetic body 95 may be exposed from the housing 140. For example, at least one of the two ends (e.g., one end and the other end) of the magnetic body 95 may be exposed from the housing 140.

[0287] The exposed portion of the magnetic body 95 may be the portion remaining after the magnetic body 95 has been cut following insert injection molding. In another embodiment, the magnetic body 95 may be bonded or attached to the housing 140 by an adhesive or fastening member.

[0288] The magnetic body 95 may be located at the lower part of the housing 140. For example, the magnetic body 95 may be located closer to the lower surface of the housing 140 than the rotating body 110. For example, the magnetic body 95 may be located closer to the lower surface of the housing 140 than the upper surface of the housing 140.

[0289] For example, the magnetic body 95 may be located below the coil 120. For example, the magnetic body 95 may be spaced apart from the coil 120. For example, the magnetic body 95 may include a portion that overlaps with the coil 120 in the first direction. Alternatively, for example, the magnetic body 95 may include a portion that does not overlap with the coil 120 in the first direction.

[0290] Magnetic body 95 can generate an attractive force with magnet 130. For example, an attractive force can be applied between magnetic body 95 and magnet 130 in a direction where they face each other. The attractive force applied between magnetic body 95 and magnet 130 can be referred to as "holding force", "adhesive force" or "holding force".

[0291] The magnetic body 95 can be made of a material that is attracted to a magnet. For example, the magnetic body 95 can be made of a metallic material. Or, for example, the magnetic body 95 can be made of a magnetic metallic material. Or, for example, the magnetic body 95 can be a magnet.

[0292] The magnetic body 95 may be alternatively referred to as "yoke", "magnetic conductor", "magnetic component", "magnetic plate", "magnetic plate" or "magnetic yoke".

[0293] The magnetic body 95 can be located below the magnet 130. For example, the magnetic body 95 can be located below the lower surface of the magnet 130.

[0294] The magnetic body 95 may not overlap with the magnet 130 in a first direction (or optical axis direction). The magnet 130 and the coil 120 may be positioned facing each other in a direction perpendicular to the optical axis (e.g., a "second direction"). The magnet 130 may be disposed on the rotating body 110, and the coil 120 and the magnetic body 95 may be disposed within the housing 140. To avoid spatial interference between the magnetic body 95 and the coil 120, the magnetic body 95 may be located below the coil 120. At least a portion of the magnetic body 95 may overlap with the coil 120 in the optical axis direction. Additionally, at least one other portion of the magnetic body 95 may not overlap with the coil 120 in the optical axis direction. For example, the length of a portion of the magnetic body 95 that does not overlap with the coil 120 may be greater than the length of another portion of the magnetic body 95 that overlaps with the coil 120.

[0295] Reference Figure 14b When viewed along the first direction or from below, the magnetic body 95 may be located further outward than the magnet 130. For example, when viewed along the first direction or from below, the magnetic body 95 may be located further outward than the outer surface of the magnet 130.

[0296] In another embodiment, when viewed along the first direction or from below, the magnetic body 95 may be located further inside the magnet 130. In yet another embodiment, the magnetic body 95 may include a portion that overlaps with the magnet 130 in the first direction. In still another embodiment, at least a portion of the magnetic body 95 may overlap with the magnet 130 in the first direction.

[0297] The magnetic body 95 may include a first magnetic body 95A corresponding to or facing the first magnetic body unit 130A and a second magnetic body 95B corresponding to or facing the second magnetic body unit 130B. The first magnetic body 95A and the second magnetic body 95B may be spaced apart from each other. In another embodiment, the first magnetic body 95A and the second magnetic body 95B may be connected to each other.

[0298] The first magnetic body 95A may include a curved shape formed along the lower surface or lower portion of the housing 140. For example, the first magnetic body 95A may have a plate-like shape that is curved in the circumferential direction of the housing 140.

[0299] Reference Figure 12e and Figure 13c At least a portion of the first magnetic body 95A may face or overlap with the first coil unit 120A in the first direction. At least a portion of the first magnetic body 95A may overlap with the position sensor 170 in the first direction. Alternatively, for example, at least one other portion of the first magnetic body 95A may not overlap with the position sensor 170.

[0300] The second magnetic body 95B may have a shape that is symmetrical with respect to the opening 501 of the housing 140 or the optical axis of the first magnetic body 95A. The description of the shape of the first magnetic body 95A may be applied equally or similarly to the second magnetic body 95B.

[0301] Reference Figure 14b and Figure 14c The length K1 of the first magnetic body 95A can be greater than the length M1 of the first magnetic unit 130A. For example, the length K1 can be the length of the first magnetic body 95A in the circumferential direction of the housing 140. For example, the length K1 can be the length from one end (first end) 92A of the first magnetic body 95A to the other end (second end) 92B of the first magnetic body 95A. For example, the length K1 can be the minimum length from one end (first end) 92A of the first magnetic body 95A to the other end (second end) 92B of the first magnetic body 95A.

[0302] For example, the first end 92A may be a portion of the first magnetic body 92A exposed from the outer surface of the housing 140, and the second end 92B may be another portion of the first magnetic body 95A exposed from the outer surface of the housing 140.

[0303] For example, length M1 can be the length of the first magnet unit 130A in the circumferential direction of the rotating body 110. For example, length M1 can be the length of the outer surface of the first magnet unit 130A. For example, length M1 can be the distance between the two ends of the first magnet units 130A facing each other in the circumferential direction of the rotating body 110. In another embodiment, length M1 can be the minimum distance between the two ends of the first magnet unit 130A.

[0304] Because length K1 is greater than length M1, the portion of the rotating body 110 affected by the attractive force applied between the first magnet unit 130A and the first magnet 95A can be increased. Therefore, the rotating body 110 can stably receive the holding force or gripping force. As a result, the blade portion 150 can move stably and accurately, and the size of the opening 201 of the blade portion 150 can change accurately and stably.

[0305] For example, the length K1 of the magnetic body 95 can be at least twice the length M1 of the magnetic unit 130A or 130B. For example, the length K1 of the magnetic body 95 can be two to ten times the length M1 of the magnetic unit 130A or 130B. For example, the length K1 of the magnetic body 95 can be three to five times the length M1 of the magnetic unit 130A or 130B.

[0306] If the length K1 of the magnetic body 95 is less than or slightly greater than the length M1 of the magnetic unit 130A or 130B, then when the magnetic unit 130A or 130B rotates or moves, there may be a significant difference between the force applied to the magnetic unit 130A or 130B by a portion of the magnetic body 95 located to the left of the magnetic unit 95 and the force applied to the magnetic unit 130A or 130B by a portion of the magnetic body 95 located to the right of the magnetic unit 95. The circumferential torque caused by this difference in forces may lead to deformation of the rotating body 110, or may adversely affect the rotation of the rotating body 110.

[0307] In this embodiment, since the length of the magnetic body 95 is greater than the length of the magnet 130, a uniform adhesive or attractive force can be maintained throughout the entire rotational section (or range) of the rotating body 110, thereby stably supporting the rotating body 110. Furthermore, in this embodiment, since the length of the magnetic body 95 is much greater than the length of the magnet 130 (i.e., at least twice its length), the difference between the force applied to magnet units 130A or 130B by the portion of the magnetic body 95 located to the left of magnet units 130A or 130B and the force applied to magnet units 130A or 130B by the portion of the magnetic body 95 located to the right of magnet units 130A or 130B may be very small, or the resultant force obtained by adding the two forces may be almost zero. Therefore, the generation of torque affecting the rotating body 110 in the circumferential direction can be minimized, and the rotating body 110 can be stably supported.

[0308] The length K1 of the first magnetic body 95A can be greater than the size (or distance) of the rotation range 622 of the first magnetic unit 130A (or the first extension 110B1). The rotation range 622 can be the distance from a first position of the first magnetic unit 130A (or the first extension 110B1) to a second position of the first magnetic unit 130A (or the first extension 110B1). The first position can be the maximum movement position or the maximum rotation position of the first magnetic unit 130A (or the first extension 110B1) in the clockwise direction. The second position can be the maximum movement position or the maximum rotation position of the first magnetic unit 130A (or the first extension 110B1) in the counterclockwise direction.

[0309] Because the length of the first magnetic body 95A is greater than the distance of the rotation range 622, the rotating body 110 can stably receive the attractive force applied between the first magnetic body 95A and the first magnetic unit 130A within its rotation range. Therefore, the rotating body 110 can stably receive the holding force or gripping force throughout the entire section of its rotation. Thus, the blade portion 150 can move stably and accurately, and the size of the opening 201 of the blade portion 150 can change accurately and stably.

[0310] Reference Figure 14c The first magnetic body 95A may include a first part 97A adjacent to the first magnetic unit 130A, a second part 97B connecting the first part 97A and the first end 92A, and a third part 97C connecting the first part 97A and the second end 92B.

[0311] The first portion 97A of the first magnetic body 95A may include a bent or curved region. The first portion 97A may be located closer to the first magnetic unit 130A than the first end 92A. The second portion 97B may be located closer to the first end 92A than the first magnetic unit 130A. The third portion 97C may be located closer to the first end 92A than the first magnetic unit 130A.

[0312] The first portion 97A may include a first region 81A having a width W1 greater than the width W2 of the second portion 97B or the width W4 of the third portion 97C (W1>W2). For example, the width W2 may be equal to the width W4. In another embodiment, the widths W2 and W4 may be different from each other.

[0313] The first portion 97A may include a second region 81B having a width W3 that is smaller than the width W1 of the first region 81A. The first region 81A of the first portion 97A may be located between the second portion 97B and the second region 81B of the first portion 97A.

[0314] The first portion 97A may include a second region 81B having a width W3 that is smaller than the width W1 of the first region 81A. The first region 81A of the first portion 97A may be located between the second portion 97B and the second region 81B of the first portion 97A.

[0315] The first portion 97A may include a third region 81C having a width W5 greater than or equal to the width W2 or W4 of the third portion 97C (W5>W4). The third region 81C may be located between the second region 81B and the third portion 97C. The width W5 of the third region 81C may be greater than the width W3 of the second region 81B (W5>W3). For example, widths W1 and W5 may be equal to each other. In another embodiment, widths W1 and W5 may be different from each other.

[0316] The second region 81B of the first part 97A can be a clearance region to avoid spatial interference with the reinforcing member 70A. For example, the outer surface of the second region 81B of the first part 97A can have a straight shape.

[0317] In another embodiment, the width of the second region 81B of the first portion 97A may be equal to the width of the first region 81A or the width of the third region 81C.

[0318] In the embodiment, because the width W1 of the first region W1 of the first part 97A is greater than the width W2 of the second part 97B and the width W4 of the third part 97C, the attraction between the magnet 130 and the first magnetic body 95A can be increased, and the rotating body 110 can be stably supported.

[0319] exist Figure 12d , Figure 12e , Figure 14b and Figure 14c In the text, the descriptions of the first coil unit 120A, the first magnet unit 130A, and the first magnetic body 95A can be applied equally or similarly to the second coil unit 120B, the second magnet unit 130B, and the second magnetic body 95B, respectively.

[0320] In addition, Figure 12d , Figure 12e , Figure 14b and Figure 14c In this context, the description of the correlation between the first coil unit 120A, the first magnet unit 130A, and the first magnet body 95A can be applied equally or similarly to the correlation between the second coil unit 120B, the second magnet unit 130B, and the second magnet body 95B.

[0321] Because magnet 130 is disposed on rotating body 110 and magnetic body 95 is disposed in housing 140, rotating body 110 can be attracted downward or toward housing 140 by the attractive force applied between magnetic body 95 and magnet 130. Rotating body 110 can be attracted downward or toward housing 140 by the attractive force F1 applied between first magnetic unit 130A and first magnetic body 95A and the attractive force F2 applied between second magnetic unit 130B and second magnetic body 95B.

[0322] The rotating body 110 and the housing 140 can press the rolling member 40 using the attraction force applied between the magnetic body 95 and the magnet 130. For example, the support portion 47 of the rotating body 110 and the receiving portion 33 of the housing 140 can press the rolling member 40 using the attraction force applied between the magnetic body 95 and the magnet 130. Because the rotating body 110 and the housing 140 press the rolling member 40, the rotating body 110 can be stably supported by the rolling member 40.

[0323] Magnetic bodies 95 and 130 can be "pressing units" or "pressing members". These pressing units maintain contact between the rotating body 110 and the rolling member 40, and between the rolling member 40 and the housing 140, as the rotating body 110 rotates or moves. Due to the attractive force applied between the magnet 130 and the magnetic body 95, the rolling member 40 can stably support the rotating body 110 relative to the housing 140.

[0324] Reference Figure 11a and Figure 11b When the rotating body 110 moves or rotates, the drive shafts 51A to 51F of the rotating body 110, which are fitted into the holes 3A to 3D in the blades 150A to 150F, can move. As the drive shafts 51A to 51F of the rotating body 110 move, the blades 150A to 150F can fold toward the optical axis or unfold outward.

[0325] Figure 11a The diagram shows the opening 201A of the blade portion 150 when it is fully open. The size (e.g., area or diameter) of the opening 201A may be larger than the size (e.g., area or diameter) of the opening 205 of the support plate 160. The opening 201A may expose or keep the opening 205 of the support plate 160 entirely open.

[0326] Figure 11b The diagram shows the opening 201B of the blade portion 150 when it is fully closed. The size (e.g., area or diameter) of the opening 201B may be smaller than the size (e.g., area or diameter) of the opening 205 of the support plate 160. The opening 201B may expose or remain open a portion of the opening 205 of the support plate 160. In another embodiment, the blade portion 150 may be fully closed, thus not forming an opening, and may block the entire opening 205 of the support plate 160.

[0327] The aperture module 100 may include a magnetic element 86 disposed in the housing 140.

[0328] Figure 16a This is a cross-sectional view of the rotating body 110, the magnet 130, the housing 140, and the magnetic body 86. (Refer to...) Figure 7a and Figure 16a The magnetic element 86 can be disposed between the circuit board 190 and the housing 140. For example, the magnetic element 86 can be disposed between the third portion 191C of the first circuit board 191 and the outer peripheral surface (or outer surface) of the housing 140. The magnetic element 86 can be disposed in the receiving portion 44 of the housing 140. For example, the magnetic element 86 can have a structure in which the protrusions 43A and 43B of the housing 140 are avoided. For example, at least a portion of the magnetic element 86 can be disposed between the two protrusions 43A and 43B of the housing 140. Although in Figure 6aThe magnetic body 86 is shown as having a T-shape when viewed in the circumferential direction of the housing 140, but this disclosure is not limited thereto. In another embodiment, the magnetic body 86 may have a polygonal or circular shape.

[0329] The magnetic body 86 can be located higher than the magnetic body 95. For example, the magnetic body 86 can be located lower than the upper end or upper surface of the coil 120 (e.g., the first coil unit 120A). Alternatively, the magnetic body 86 can be located higher than the lower end or lower surface of the coil 120 (e.g., the first coil unit 120A). The magnetic body 86 can be disposed adjacent to one end of the first magnetic unit 130A. For example, the magnetic body 86 can be disposed in the region of the housing 140 adjacent to one end of the first magnetic unit 130A when the opening 201 of the blade portion 150 is fully open. For example, the magnetic body 86 can be configured to be closer to the position of the first magnetic unit 130A when the opening 201 of the blade portion 150 is fully open, compared to the position of the first magnetic unit 130A when the opening 201 of the blade portion 150 is fully closed. The magnetic body 86 can be closer to the first magnetic unit 130A than the second magnetic unit 130B.

[0330] The magnetic body 86 can be made of a material that is attracted to a magnet. For example, the magnetic body 86 can be made of a metallic material. Alternatively, for example, the magnetic body 86 can be made of a magnetic metallic material. Alternatively, for example, the magnetic body 86 can be a magnet. The magnetic body 86 can be alternatively referred to as a "yoke," "magnetic conductor," "magnetic component," "magnetic plate," "magnetic plate," or "magnetic yoke."

[0331] The magnetic body 86 can generate an attractive force F3 with the magnetic body 130 (e.g., the first magnetic unit 130A). For example, an attractive force can be applied between the magnetic body 86 and the first magnetic unit 130A in the circumferential direction of the rotating body 110. Due to the attractive force F3 applied between the magnetic body 86 and the first magnetic unit 130A, the first magnetic unit 130A can be attracted toward the magnetic body 86, and the rotating body 110 can be attracted toward the portion of the housing 140 where the magnetic body 86 is located.

[0332] The magnet 86 can be used to keep the opening 201 of the blade portion 150 fully open when no drive signal is provided to the coil 120 and therefore no electromagnetic force is generated between the coil 120 and the magnet. Therefore, when no electromagnetic force is generated between the coil 120 and the magnet, the opening 201 of the blade portion 150 can be fully open, thereby minimizing the exposure of the blade portion 150 to the outside.

[0333] Figure 16b It is a cross-sectional view of the rotating body 110, the magnet 130, the shell 140, and the magnetic bodies 86 and 87.

[0334] Reference Figure 16b Camera device 200 Figure 16a In addition to the magnetic body 86, the housing 140 may also include a magnetic body 87. The magnetic body 87 may be disposed within the housing 140. The housing 140 may include a receiving portion (not shown) for accommodating the magnetic body 87. In this case, the description of the receiving portion 44 may be applied equivalently or similarly to the receiving portion (not shown). Furthermore, the description of the shape and material of the magnetic body 86 may be applied equivalently or similarly to the magnetic body 87.

[0335] The magnetic body 87 can be positioned closer to the second magnetic unit 130B than the first magnetic unit 130A. For example, an attractive force F4 can be applied between the magnetic body 87 and the second magnetic unit 130B in the circumferential direction of the rotating body 110. Due to the attractive force F4 applied between the magnetic body 87 and the second magnetic unit 130B, the second magnetic unit 130B can be attracted toward the magnetic body 87, and the rotating body 110 can be attracted toward the portion of the housing 140 where the magnetic body 87 is located. The magnetic body 86 can perform the same function as the magnetic body 87.

[0336] In another embodiment, the magnet 86 (or 87) may be configured to be closer to the position of the first magnet unit 130A (or the second magnet unit 130B) when the opening 201 of the blade portion 150 is fully closed, compared to the position of the first magnet unit 130A (or the second magnet unit 130B) when the opening 201 of the blade portion 150 is fully open. In another embodiment, the magnets 86 and 87 may be used to keep the opening 201 of the blade portion 150 in a fully closed state when a drive signal is not provided to the coil 120 and therefore no electromagnetic force is generated between the coil 120 and the magnet.

[0337] Reference Figures 13a to 13c The lens module 400 may include a lens barrel 510 and a lens unit 30 disposed in the lens barrel 510. The lens unit 30 may include a plurality of lenses disposed or stacked in the optical axis direction.

[0338] The lens barrel 510 may include an upper end portion 511, a lower end portion 512 disposed below the upper end portion 511, and an intermediate portion 513 disposed between the upper end portion 511 and the lower end portion 512 to connect the upper end portion 511 and the lower end portion 512 to each other. In another embodiment, the intermediate portion 513 may be omitted.

[0339] The diameter (or length in the direction perpendicular to the optical axis) of the upper end portion 511 may be smaller than the diameter (or length in the direction perpendicular to the optical axis) of the lower end portion 512. The middle portion 513 may include a portion whose diameter decreases in the direction from the upper end portion 512 toward the lower end portion 512. For example, the diameter of the middle portion 513 may gradually decrease in the direction from the upper end portion 512 toward the lower end portion 512. Protrusions 521 to 524 may be provided on the upper surface of the lower end portion 512.

[0340] The upper end portion 512 of the lens barrel 510 can be disposed within the housing 140 of the aperture module 100. Additionally, at least a portion of the middle portion 513 of the lens barrel 510 can be disposed within the housing 140 of the aperture module 100. The housing 140 of the aperture module 100 can be attached to the lower end portion 513 of the lens barrel 510.

[0341] The upper end portion 511 of the lens barrel 510 may face or overlap with the magnet 130 in a direction perpendicular to the optical axis. The upper end portion 511 of the lens barrel 510 may face or overlap with the coil 120 in a direction perpendicular to the optical axis. The upper end portion 511 of the lens barrel 510 may face or overlap with the position sensor 170 in a direction perpendicular to the optical axis. At least a portion of the magnet 130 and at least a portion of the coil 120 may face or overlap with the middle portion 513 of the lens barrel 510 in a direction perpendicular to the optical axis.

[0342] Magnet 130 may face or overlap with the middle portion 513 in the first direction. In another embodiment, magnet 130 may face or overlap with the lower end portion 512 in the first direction. Coil 120 may face or overlap with either the middle portion 513 or the lower end portion 512 in the first direction. Magnet 130 and coil 120 may not overlap with the upper end portion 511 of the lens barrel 510 in the first direction.

[0343] In addition, in the embodiment, since the coil 120 and the magnet 130 overlap with the upper end 511 and the middle part 513 of the lens barrel 510 in the direction perpendicular to the optical axis, and do not overlap with the upper end 511 in the direction of the optical axis, the size of the camera device 200 in the direction perpendicular to the optical axis can be prevented from increasing.

[0344] Because the aperture module 100 according to the embodiment is configured such that the rotating body 110 and the housing 140 are arranged in a vertical direction and the rolling member 40 is disposed between the rotating body 110 and the housing 140, the assembly between the rotating body 110 and the housing 140 can be simplified. Thus, since the assembly between the rotating body 110 and the housing 140 is simplified, the structure of the rotating body 110 and the housing 140 can be simplified, thereby reducing assembly deviations.

[0345] Recesses 2A and 2B can be formed in the extension 110B of the rotating body 110, and the protrusion 64 of the housing 140 corresponding to the recesses 2A and 2B can be used as a stop for mechanically stopping the rotating body 110.

[0346] Because of the recesses 2A and 2B in the extension 110B, the rotation range of the rotating body 110 can be increased, and the range of size change of the opening 201 of the blade portion 150 can be increased.

[0347] Typically, if the rotating body of the aperture module is not stably supported and tilts during its rotation, the center of the aperture module opening may not be aligned with the center of the lens unit (or the optical axis), or there may be an eccentricity between the center of the lens unit (or the optical axis) and the center of the aperture module opening.

[0348] In this embodiment, because the rolling member 40 is disposed in the receiving portion 33 formed in the upper surface of the housing 140, the rolling member 40 can be stably and easily placed in the housing 140. Furthermore, due to the attraction force applied between the magnet 130 and the magnetic body 95 disposed in the housing 140, the rotating body 110 can press the rolling member 40 from top to bottom, and the housing 140 can press the rolling member 40 from bottom to top. Therefore, the rotating body 110 can stably and tightly contact the rolling member 40. Thus, when the rotating body 110 moves or rotates, the rotating body 110 can stably and tightly contact the rolling member 40, thereby allowing the size of the opening 201 of the blade portion 150 to change stably and preventing misalignment between the center of the aperture module opening and the center (or optical axis) of the lens unit. Furthermore, eccentricity between the center (or optical axis) of the lens unit and the center of the aperture module opening can be suppressed.

[0349] Because the length of the magnetic body 95 is greater than the length of the magnet 130, it can stably support the rotating body 110. Furthermore, since the magnet 130 and the magnetic body 95 do not overlap each other in the optical axis direction, and at least a portion of the coil 120 and the magnetic body 95 overlap each other in the optical axis direction, spatial interference between the magnetic body 95 and the coil 120 can be avoided. The magnetic body 95 can be designed to have a long length, and the attractive force or holding force between the magnetic body 95 and the magnet 130 can be increased.

[0350] Furthermore, since the outer surface 73B of the support portion 47 of the rotating body 110 that contacts the rolling member 40 is formed as an inclined surface, the support portion 47 can stably contact the rolling member 40 located in the receiving portion 33 of the housing 140, and can stably support the rotating body 110.
