[0038] The following describes an embodiment of the present invention that can specifically realize the above objectives, with reference to the attached drawings.

[0039] In the description of the embodiments, where it is stated that an element is formed "on or under," the term "on or under" includes both cases where two elements are in direct contact with each other and cases where one or more other elements are positioned indirectly between the two elements. Furthermore, when expressed as "on or under," it may include the meaning of a downward direction as well as an upward direction relative to a single element.

[0040] Additionally, relational terms used below, such as "first" and "second," "upper / superior / above," and "lower / subordinate / below," do not necessarily require or imply any physical or logical relationship or order between such entities or elements, and may be used solely to distinguish one entity or element from another. Furthermore, the same reference number indicates the same element through the description of the drawings.

[0041] Furthermore, terms such as "include," "constitute," or "have" as described above, unless specifically stated otherwise, imply that the relevant component may be inherent; therefore, they should be interpreted as allowing for the inclusion of additional components rather than excluding them. Additionally, terms such as "corresponding" as described above may include at least one of the meanings of "opposing" or "overlapping."

[0042] Hereinafter, a camera device according to an embodiment and an optical device including the same will be described as follows with reference to the attached drawings. For convenience of explanation, the camera device according to the embodiment is described using a Cartesian coordinate system (x, y, z), but may be described using other coordinate systems, and the embodiment is not limited thereto. In each drawing, the X-axis and the Y-axis may refer to directions perpendicular to the Z-axis, which is the direction of the optical axis (OA). In addition, the Z-axis direction, which is the direction of the optical axis (OA), may be defined as any one of the 'first direction', 'second direction', and 'third direction', the X-axis direction may be defined as any one of the 'first direction', 'second direction', and 'third direction', and the Y-axis direction may be defined as the other one among the 'first direction', 'second direction', and 'third direction'.

[0043] Additionally, the X-axis can be defined as either the "first axis" or the "second axis," the X-axis direction can be defined as either the "first axis direction" or the "second axis direction," the Y-axis can be defined as the other of the "first axis" and the "second axis," and the Y-axis direction can be defined as the other of the "first axis direction" and the "second axis direction."

[0044] Additionally, the optical axis (OA) may be the optical axis of a lens mounted on a lens barrel. Alternatively, the optical axis (OA) may be an axis perpendicular to the imaging area of ​​the image sensor and passing through the center of the imaging area. Also, the expression "terminal" below may be replaced with a pad, electrode, or conductive layer. Below, "acquire" may be replaced with "calculate," "detect," or "generate."

[0045] The camera device according to the embodiment may perform either a hand image stabilization function or an auto-focusing function, or perform both a hand image stabilization function and an auto-focusing function. The "hand image stabilization function" may 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 cancel out vibrations (or movements) caused by the user's hand shake. Additionally, the "auto-focusing function" may be a function that automatically focuses on a subject by moving the lens in the direction of the optical axis according to the distance to the subject in order to obtain a clear image of the subject on the image sensor. Hereinafter, "camera device" may be replaced with "camera," "actuator," "hand image stabilization device," "camera module," "imaging device," or "photographer."

The first region (62A, 62B) may overlap with the first axis (701). A first ball member (B1, B2) may be disposed in the first region (62A, 62B) of the second tilt carrier (160). For example, the first ball member (B1, B2) may be in contact with the first region (62A, 62B) of the second tilt carrier (160). A groove (16) for disposing of the first ball member (B1, B2) may be formed in the first region (62A, 62B).

[0120] Additionally, the second tilt carrier (160) may include a second region (62C, 62D) that overlaps with at least a portion of the base (210) in the direction of the optical axis (e.g., a protrusion (44)). The second region (62C, 62D) may overlap with the second axis (702). A ball member (B3, B4) may be positioned below the second region (62C, 62D) of the tilt carrier (160). For example, the ball member (B3, B4) may come into contact with the second region (62C, 62D) of the second tilt carrier (160). A groove (65) for positioning the ball member (B3, B4) may be formed in the second region (62C, 62D).

[0121] Additionally, the tilt carrier (160) may include a third area (61) connecting the first area (62A, 62B) and the second area (62C, 62D). The first area (62A, 62B) and the second area (62C, 62D) may protrude downward from the third area (61). The lower surface or bottom of each of the first area (62A, 62B) and the second area (62C, 62D) may be positioned lower than the lower surface or bottom of the third area (61).

[0122] A space (10A to 10D) exists between the first region (62A, 62B) and the second region (62C, 62D) located below the third region (61). In the direction of the optical axis, the third region (61) may include a portion (61A, 61D) that overlaps with the magnet units (23A, 23B) of the OIS magnet (23), and the space (10A to 10D) may serve to avoid spatial interference between the magnet units (23A, 23B) and the second tilt carrier (160). As a result, the size of the camera device (200) in the direction of the optical axis and the size in the direction perpendicular to the optical axis can be reduced.

[0123] In addition, because there is space (10A to 10D), spatial interference between the connecting board (815) and the second tilting carrier (160) can be prevented. The connecting board (815) elastically supports the OIS moving part, but if the movement of the connecting board (815) is restricted due to spatial interference with the second tilting carrier (160), power consumption to move the OIS moving part may increase during hand tremor correction, and oscillation of the OIS moving part may occur, making it impossible to perform stable OIS operation.

[0124] The third region (61) of the second tilt carrier (160) may include a first guide (61A) corresponding to or opposite to the first side (71A) of the base (210), a second guide (61B) corresponding to or opposite to the second side (71B) of the base (210), a third guide (61C) corresponding to or opposite to the third side (71C) of the base (210), and a fourth guide (61D) corresponding to or opposite to the fourth side (71D) of the base (210). Each of the first to fourth guides (61A to 61D) may extend in a direction parallel to any one of the first to fourth sides (71A to 71D) of the base (210). The first and second guides (61A, 61B) may be located opposite each other in the first direction (X-axis direction), and the third and fourth guides (61C, 61D) may be located opposite each other in the second direction (Y-axis direction). The second tilt carrier (160) may include a hole penetrating the second tilt carrier (160) in the optical axis direction, and the hole of the second tilt carrier (160) may overlap with the lens module (400) in the optical axis direction.

[0125] In the first region (62A, 62B) of the second tilt carrier (160), a receiving portion (16) may be formed to receive a protrusion (150B) of the first tilt carrier (150) or to insert the protrusion (150B). The receiving portion (16) may be a groove that is recessed from the upper surface of the tilt carrier (160). The receiving portion (16) of the second tilt carrier (160) may correspond to, oppose, or overlap with the protrusion (150B) of the first tilt carrier (150) in the direction of the optical axis. The receiving portion (16) may include an opening that is opened in a direction parallel to the first axis (701) to allow the protrusion (150B) to be inserted. The protrusion (150B) of the first tilt carrier (150) may overlap with the receiving portion (16) of the second tilt carrier (160) in a direction perpendicular to the optical axis.

[0126] The protrusion (150B) of the first tilt carrier (150) can be placed within the receiving portion (16) of the second tilt carrier (160), thereby preventing the first tilt carrier (150) and the second tilt carrier (160) from being separated or detached from each other due to external impact, improving the bonding strength between the first tilt carrier (150) and the second tilt carrier (160), and improving the reliability of the OIS operation.

[0127] In addition, since the protrusion (150B) of the first tilt carrier (150) and the receiving portion (16) of the second tilt carrier (160) overlap each other in a direction perpendicular to the optical axis direction, it is possible to prevent the OIS moving portion (100) from being abnormally and excessively twisted.

[0128] At least a portion of the protrusion (150B) of the first tilt carrier (150) may be disposed within the receiving portion (16) of the second tilt carrier (160). The protrusion (150B) may overlap with the second tilt carrier (160) in a direction perpendicular to the optical axis. A first ball member (B1, B2) may be disposed between the protrusion (150B) of the first tilt carrier (150) and the receiving portion (16) of the second tilt carrier (160). A groove (63A, 63B) may be formed in the receiving portion (16) of the second tilt carrier (160) to accommodate a portion of the first ball member (B1, B2). The groove (63A, 63B) may be formed on the bottom surface of the receiving portion (16).

[0129] The receiving portion (16) of the second tilt carrier (160) may include a first receiving portion (16A) and a second receiving portion (16B) located opposite each other with respect to the optical axis. The first and second receiving portions (16A, 16B) may be located opposite each other in a direction parallel to the first axis (701). At least a portion of the first protrusion (151) of the first tilt carrier (150) may be placed within the first receiving portion (16A) of the second tilt carrier (160), and at least a portion of the second protrusion (152) of the second tilt carrier (150) may be placed within the second receiving portion (16B) of the second tilt carrier (160).

[0130] The first region (62A, 62B) of the second tilt carrier (160) may include a first connecting part (62A) connecting the first guide (61A) and the third guide (61C), and a second connecting part (62B) connecting the second guide (61B) and the fourth guide (61D). Additionally, the second region (62C, 62D) of the second tilt carrier (160) may include a third connecting part (62C) connecting the first guide (61A) and the fourth guide (61D), and a fourth connecting part (62D) connecting the second guide (61B) and the third guide (61C).

[0131] Each of the first and second tilt carriers (150, 160) may be formed from an injection molded material, such as plastic, resin, or ceramic. The first tilt carrier (150) may be formed from an injection molded material with a metal member inserted therein. Additionally, the second tilt carrier (160) may be formed from an injection molded material with a metal member (64) inserted therein.

[0132] The support member may include a first ball member (B1, B2) positioned between the first tilt carrier (150) and the second tilt carrier (160). Additionally, the support member may include a second ball member (B3, B4) positioned between the second tilt carrier (160) and the fixed member (base (210)). The first ball member (B1, B2) may be positioned to overlap with the first axis (701), and the second ball member (B3, B4) may be positioned to overlap with the second axis (702).

[0133] The first ball member (B1, B2) may include a plurality of balls spaced apart in a direction parallel to the first axis (701). The second ball member (B3, B4) may include a plurality of balls spaced apart in a direction parallel to the second axis (702). The first axis (701) may be a straight line parallel to the first direction (X-axis direction) or a straight line intersecting a straight line parallel to the second direction (Y-axis direction). For example, the first axis (701) may be a straight line perpendicular to the optical axis and passing through the first ball member (B1, B2). For example, the first axis (701) may be a straight line connecting the center of the first ball (B1) and the center of the second ball (B2). For example, the first axis (701) may pass through the optical axis or the center of the OIS moving part. For example, the center of the OIS moving part may be the center of the opening of the bobbin (110) or the center of the lens module (400). The second axis (702) may be a straight line perpendicular to the optical axis (OA) and passing through the second ball members (B3, B4). For example, the second axis (702) may be a straight line connecting the center of the third ball (B3) and the center of the fourth ball (B4). The second axis (702) may intersect the first axis (601). For example, the first axis (701) and the second axis (702) may be perpendicular to each other. The second axis (702) may be a straight line passing through the optical axis.

[0134] The first axis direction may be a direction parallel to the first axis (701), and the second axis direction may be a direction parallel to the second axis (702). The ball members (B1 to B4) may not overlap with the image sensor (810) or lens module (400) in the optical axis direction.

[0135] In another embodiment, instead of the first ball member (B1, B2) and the groove (16), a protrusion (or hemisphere) may be formed in the first region (62A, 62A) of the second tilt carrier (160), and instead of the second ball member (B3, B4) and the groove (65), a protrusion (or hemisphere) may be formed in the second region (62C, 62D) of the second tilt carrier (160).

[0136] Referring to FIGS. 10c and 10d, the first ball members (B1, B2) may be positioned higher than the second ball members (B3, B4) relative to the lower part (214) of the base (210). The first axis (701) may be positioned higher than the second axis (702) relative to the lower part (214) of the base (210). In another embodiment, the heights of the first ball members (B1, B2) and the second ball members may be the same.

[0137] To reduce friction and reduce power consumption, a lubricant may be disposed in at least one of the grooves (51, 52) of the first tilt carrier (150), the grooves (75A, 75B) of the base (210), and the grooves (16, 65) of the second tilt carrier (160). The ball members (B1 to B4) may be members that perform rolling or sliding motion. In the embodiment, four balls (B1 to B4) are exemplified, but in other embodiments, the number of balls may be two, three, or five or more.

[0138] The second tilt carrier (160) can be positioned higher than the image sensor (810), and the ball members (B1 to B4) can be positioned higher than the image sensor (810). Since the ball members (B1 to B4) are positioned higher than the image sensor (810), the ball members (B1 to B4) can be positioned close to the lens module (400). The drive shafts (701, 702) for tilting the OIS moving part can be positioned higher than the image sensor (810) and close to the lens module (400). As a result, when not performing OIS operation, the degree to which the lens module (400) is tilted can be reduced. When OIS operation is not performed, the aesthetics may be poor if the tilting of the camera device (200) is large. In the embodiment, the drive shafts (701, 702) formed by the second tilt carrier (160) and ball members (B1 to B4) can be arranged adjacent to the lens module (400), thereby improving the aesthetics of the optical device (200A) equipped with the camera device (200).

[0139] The support member may include a magnetic body (31) that is placed on or coupled to the OIS moving member (e.g., sensor base (270)) and a magnetic body (32) that is placed on or coupled to the fixed member (e.g., base (210)). The magnetic body (31) and the magnetic body (32) may be replaced with "magnet," "yoke," "holding magnet," "preload plate," or "preload magnet." The magnetic body (31) may face or overlap with the through hole of the second tilt carrier (160) or the lens module (400) in the direction of the optical axis.

[0140] The magnetic body (32) may be placed below the magnetic body (31). The magnetic body (32) may overlap with the magnetic body (31) in the direction of the optical axis. The magnetic body (32) may overlap with the through hole of the second tilt carrier (160) in the direction of the optical axis. The magnetic body (32) may not overlap with the second tilt carrier (160) in a direction perpendicular to the optical axis. An attractive force may act between the magnetic body (32) and the magnetic body (31) in the direction of the optical axis (or the first direction). For example, the magnetic body (32) may be a magnet, and the magnetic body (31) may be a metal plate attached to the magnet. In another embodiment, the magnetic body (31) may be a magnet, and the magnetic body (32) may be a metal plate attached to the magnet. Due to the attractive force between the magnetic body (32) and the magnetic body (31), the first tilt carrier (150) and the base (210) can press the second tilt carrier (160), and the second tilt carrier (160) and the ball members (B1 to B4) can be in close contact with the first tilt carrier (150), the second tilt carrier, and the base (210). Due to the attractive force between the magnetic body (32) and the magnetic body (31), the first tilt carrier (150), the second tilt carrier (160), and the ball members (B1 to B4) can stably support the OIS moving part (100) with respect to the fixed part, and stable OIS operation can be performed.

[0141] For hand shake correction, the OIS drive unit may tilt the OIS moving unit (100) based on the first axis (701) or the second axis (702) or rotate it within a preset angle range. The OIS drive unit may include a magnet (23) and a coil (230). The OIS drive unit may include an OIS position sensor (24). The drive unit of the camera device (200) may include an AF drive unit and an OIS drive unit.

[0142] A first electromagnetic force may be generated by the interaction between the first magnet unit (23A) and the first coil unit (230A), and a second electromagnetic force may be generated by the interaction between the second magnet unit (23B) and the second coil unit (230B). Due to the first and second electromagnetic forces, the first tilt carrier (150) may be tilted about the first axis (701) or rotated by a preset angle. Additionally, due to the first and second electromagnetic forces, the second tilt carrier (160) may be tilted about the second axis (702) or rotated by a preset angle.

[0143] The first tilt carrier (150) can be tilted or rotated relative to the second tilt carrier (160) with respect to the first axis (701). The second tilt carrier (160) can be tilted or rotated relative to the second axis (702) with respect to the base (210). Since the first tilt carrier (150) is supported by the second tilt carrier (160) and has a structure that is coupled with the second tilt carrier (160), it can be tilted or rotated together with the second tilt carrier (160) with respect to the second axis (702).

[0144] The first tilt carrier (150) can be tilted or rotated about a first axis (701) together with the image sensor (810) and the lens module (400). The second tilt carrier (160) can be tilted about a second axis (702) together with the first tilt carrier (150), the image sensor (810), and the lens module (400).

[0145] In the embodiment, when performing hand shake correction or shake correction, the lens module (400) and the image sensor (810) may be tilted or rotated simultaneously in the same direction and by the same angle.

[0146] In the embodiment, since a part of the first tilt carrier (150) on which the ball member is placed is inserted or placed within a receiving portion formed in the second tilt carrier (160), the height of the camera device (200) in the optical axis direction can be reduced, and the first tilt carrier (150) and the second tilt carrier (160) can be prevented from separating or moving apart from each other due to external impact, thereby improving the reliability of hand shake correction.

[0147] In the embodiment, the guides (61A to 61D) of the second tilt carrier (160) are positioned higher than the first and second regions (62A to 62D) where the ball members (B1 to B4) are arranged, so spatial interference with the OIS magnet (23) can be avoided, and the height in the direction perpendicular to the optical axis of the camera device (200) can be reduced.

[0148] In the embodiment, the first to fourth guides (61A to 61D) are positioned higher than the lower portions of the first and second regions (62A to 62D), so that a space (10A to 10D) may exist, and spatial interference between the connecting substrate (815) and the second tilting carrier (160) can be prevented. As a result, stable OIS operation can be performed in the embodiment.

[0149] In addition, in the embodiment, the ball members serving as the drive axes are positioned higher than the image sensor and arranged adjacent to the lens module, so that when the camera device is deactivated or not in use, the tilting of the lens module is reduced, thereby improving the aesthetics of the camera device.

[0150] In another embodiment, the sensing magnets (80A, 80B) shown in FIG. 10d may be omitted, and the sensors (24A, 24B) may detect the driving magnet units (40A to 40D). For example, the sensors (24A, 24B) may detect the driving magnet units (40A to 40D). Or, for example, the first sensor (24A) may detect the magnet units (40C, 40D) or detect the displacement of the magnet units (40C, 40D). The second sensor (24B) may detect the magnet units (40A, 40C) (or the displacement of the magnet units (40A, 40C)) or the AF magnet (130) (or the displacement of the AF magnet (130).

[0151] In another embodiment, the positions of the OIS coil (230) and the OIS magnet (23) may be reversed. That is, the first and second magnet units of the OIS magnet may be placed on the first side (41A or 71A) of either the moving part (e.g., the first tilt carrier (150)) or the fixed part (e.g., the base (210)), and the third and fourth magnet units may be placed on the second side (41B or 71B) of either the moving part (e.g., the first tilt carrier (150)) or the fixed part (e.g., the base (210)). Additionally, the first and second coil units of the OIS coil may be placed on the first side (41A or 71A) of the remaining one of the moving part (e.g., the first tilt carrier (150)) and the fixed part (e.g., the base (210)), and the third and fourth coil units may be placed on the second side (41B or 71B) of the remaining one of the moving part (e.g., the first tilt carrier (150)) and the fixed part (e.g., the base (210)). At this time, the first axis (601) may intersect with the first side (41A or 71A) of either the moving part (e.g., the first tilt carrier (150)) and the fixed part (e.g., the base (210)). For example, the first axis (601) may be perpendicular to the first side (41A, 71A). Additionally, the second axis (602) may intersect the first axis (601). For example, the first axis (601) and the second axis (601) may be perpendicular. In another embodiment, the positions of the sensing magnets (80A, 80B) and the sensors (924A, 4B) may be opposite to each other.

[0152] In addition, the camera device (200) according to the embodiment may be included in an optical instrument that aims to increase the visual acuity of the eye by using light characteristics such as reflection, refraction, absorption, interference, and diffraction to form an image of an object in space, or to record and reproduce an image by a lens, or to perform optical measurement, propagation or transmission of an image, etc. For example, the optical instrument according to the embodiment may be a mobile phone, a smartphone, a portable smart device, a digital camera, a laptop computer, a digital broadcasting terminal, a PDA (Personal Digital Assistants), a PMP (Portable Multimedia Player), a navigation system, or a vehicle camera device, but is not limited thereto, and any device for taking images or photos is possible.

The camera device (200) included in the embodiment of FIG. 14b may be a rear camera device in which the lens module (400) is positioned to face the rear of the body (850) of the optical device (200A). FIG. 14b illustrates an example in which two rear camera devices are positioned, but in other embodiments, one or more rear camera devices may be positioned. In other embodiments, the camera device (200) may be used for both the front camera device and the rear camera device.
