[0001] The embodiment relates to a camera device and an optical device including the same.

[0002] A camera device is a device that captures a subject as a photograph or video, and is mounted on portable devices, drones, vehicles, etc. To improve image quality, the camera device may have image stabilization (IS) functions, such as Optical Image Stabilizer (OIS), and autofocus (AF) functions to correct or prevent image shaking caused by user movement.

[0003] The embodiment provides a camera device and an optical device including the same that can improve the reliability of OIS operation and reduce the length in the optical axis direction.

[0004] A camera device according to an embodiment comprises: a fixed part; a moving part including a housing, a magnet disposed in the housing, a bobbin disposed within the housing, and an image sensor facing the bobbin; and a tilting guide part disposed between the fixed part and the moving part. A driving unit comprising a magnet disposed in the housing, a first coil disposed in the bobbin and moving the bobbin in a first direction parallel to the optical axis by interaction with the magnet, and a second coil disposed in the fixed part, wherein the magnet comprises a first magnet unit and a second magnet unit located opposite each other in a second direction parallel to a first axis intersecting the optical axis, and a third magnet unit spaced apart from the first and second magnet units, and the first coil comprises a first coil unit facing the first magnet unit in the second direction and a second coil unit facing the second magnet unit in the second direction, and the second coil comprises a third coil unit located opposite the first coil unit in the second direction relative to the first magnet unit, a fourth coil unit located opposite the second coil unit in the second direction relative to the second magnet unit, and a second axis parallel to the optical axis and the first axis. The driving unit includes a fifth coil unit facing the third magnet unit in a third direction, and the driving unit tilts the moving unit with respect to the second axis through the interaction between the first and second magnet units and the third and fourth coil units, and tilts the moving unit with respect to the first axis through the interaction between the third magnet unit and the fifth coil unit.

[0005] The above magnet may not include a magnet unit positioned opposite the third magnet unit in the third direction. Each of the first to fourth coil units has a ring shape wound around the first axis, and the fifth coil unit has a ring shape wound around the second axis.

[0006] Each of the first and second magnet units may include a first magnet portion, a second magnet portion facing the first magnet portion in the first direction, and a first partition disposed between the first magnet portion and the first magnet portion. The length of the first magnet portion in the first direction may be smaller than the length of the second magnet portion in the first direction. The length of each of the first and second coil units in the first direction may be smaller than the length of each of the third and fourth coil units in the first direction.

[0007] The third magnet unit may include a third magnet portion, a fourth magnet portion facing the third magnet portion in the first direction, and a second partition wall disposed between the third magnet portion and the fourth magnet portion. The length of the third magnet portion in the first direction may be greater than the length of the first magnet portion in the first direction and smaller than the length of the second magnet portion in the first direction. The first partition wall may be positioned higher than the center of each of the first and second magnet units.

[0008] Each of the first and second magnet parts may include one N pole and one S pole, and each of the third and fourth magnet parts may include one N pole and one S pole. Each of the first and second magnet parts may include one N pole and one S pole, the third magnet part may include either one N pole or one S pole, and the fourth magnet part may include the other one of the one N pole and one S pole.

[0009] At the initial position of the bobbin, the center of the hollow of each of the first and second coil units is positioned higher than the center of the hollow of each of the third and fourth coil units, and the initial position may be the position of the bobbin when no power or driving signal is applied to the first coil. The first coil may include a connecting line connecting the first coil unit and the second coil unit.

[0010] The bobbin comprises a first side on which the first coil unit is disposed, a second side on which the second coil unit is disposed and which is located opposite the first side in the second direction, a third side facing the third magnet unit in the third direction, and a fourth side on which the third side of the bobbin is located opposite the third side in the third direction, and the connecting line may be disposed on the fourth side of the bobbin. The moving part may include an elastic member that is coupled to the bobbin and the housing.

[0011] In the embodiment, since a driving magnet unit for OIS driving is not placed on one side of the housing, the optical device can be designed to prevent magnetic field interference between the driving magnet units of adjacent camera devices.

[0012] In addition, in the embodiment, the connecting line connecting the AF coil units can be placed on the side of the bobbin facing the side of the housing where the magnet unit is not placed, making the design of the connecting line placement easy and allowing spatial interference with the magnet unit to be easily avoided.

[0013] In addition, in the embodiment, the lengths of the magnet parts of the driving magnet unit facing the AF coil in the direction of the optical axis are designed asymmetrically to prevent an increase in the length of the camera device in the direction of the optical axis and to reduce the length of the camera device in the direction of the optical axis.

[0043] The following describes an embodiment of the present invention that can specifically realize the above objectives, with reference to the attached drawings.

[0044] 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.

[0045] 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.

[0046] 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."

[0047] 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'.

[0048] 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 (or second direction)" and the "second axis direction (or third direction)."

[0049] In addition, 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.

[0050] A camera device according to an embodiment can perform an image stabilization function and an auto-focusing function. The "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," "camera module," "imaging device," or "photographer."

The first sensor (240A) is placed on the first substrate (52A) and can be electrically connected to the first substrate (52A). The second sensor unit (240B) is placed on the third substrate (52C) ​​and can be electrically connected to the third substrate (52C). The first sensor (240A) can be placed within the hollow of the first coil unit (230A), and the second sensor (240B) can be placed within the hollow of the third coil unit (230C). In another embodiment, each of the first and second sensors may be located outside the hollow of the corresponding coil unit.

[0117] Each of the first and second sensors (240A, 240B) may be a Hall sensor. Each of the first and second sensors (240A, 240B) may include first and second input terminals for receiving a power or driving signal and first and second output terminals for outputting an output signal.

[0118] The camera device (200) may include a control unit (not shown) disposed on a circuit board (250 or 800) and electrically connected to the circuit board (250 or 800). The control unit may control a first sensor (240A) and a second sensor (240B). The control unit may be disposed on the circuit board (800) and electrically connected to the circuit board (800). The control unit may supply power or a driving signal to each of the sensors (240A, 240B). The control unit may receive output signals from the sensors (240A, 240B). The control unit may supply a driving signal to the coil units (230A to 230C).

[0119] The first and second coil units (230A, 230B) may be connected in series. The control unit may supply one driving signal to the first and second coil units (230A, 230B) connected in series and another driving signal to the third coil unit (230C). In another embodiment, the control unit may supply independent driving signals to each of the first to third coil units (230A to 230C).

[0120] In another embodiment, at least one of the first and second sensors (240A, 240B) may be a driver IC including a Hall sensor. The description of the embodiment in which the position sensor (170) is a driver IC including a Hall sensor may be applied to or by analogy to the driver IC type sensors (240A, 240B).

[0121] The cover member (300) can form a receiving space together with the base (210), and an OIS moving part (100) can be disposed within the receiving space. The cover member (300) may include a top plate (301) and a side plate (302) connected to the top plate (301). The bottom of the side plate (302) of the cover member (300) may be coupled with a step (411) of the base (210). An opening (303) for exposing a lens (not shown) to external light may be formed in the top plate (302) of the cover member (300). The cover member (300) may include an opening (304) formed in the side plate (302) to avoid spatial interference with a part of the third substrate (813) of the circuit board (190).

[0122] The following explains the support section.

[0123] A support member may be positioned between a fixed member and an OIS moving member. The support member may support the OIS moving member with respect to the fixed member. The support member may be positioned between a sensor base (270) and a base (210), and may support the sensor base (270) with respect to the base (210). The support member may include a tilting guide member (60) positioned between the sensor base (270) and the base (210). Additionally, the support member may include a first ball member (3A, 3B) positioned between the tilting guide member (60) and the sensor base (270). Additionally, the support member may include a second ball member (4A, 4B) positioned between the tilting guide member (60) and the base (210).

[0124] The tilting guide portion (60) may be expressed as a moving plate, "mover," "mover plate," "drive plate," "moving plate," "drive plate," "plate," "rotating plate," "tilting plate," "moving plate," or "support plate." The tilting guide portion (60) may be tiltable or rotatable by a preset angle with respect to a first axis or a second axis. The tilting guide portion (60) may include a body or a body. The tilting guide portion (60) may be in the form of a plate.

[0125] The tilting guide portion (60) may include first holes (65A, 65B) (or first grooves) for at least a portion of the first ball member (3A, 3B) to be placed or seated. The tilting guide portion (60) may include second holes (66A, 66B) (or second grooves) for at least a portion of the second ball member (4A, 4B) to be placed or seated. The placement or arrangement direction of the first holes (65A, 65B) may intersect with the placement or arrangement direction of the second holes (66A, 66B). In another embodiment, the first ball member (3A, 3B) and the first holes (65A, 65B) may be omitted, and the tilting guide portion may include first protrusions formed at positions corresponding to the first holes (65A, 65B). In addition, in another embodiment, the second ball member (4A, 4B) and the second holes (66A, 66B) may be omitted, and the tilting guide may include second protrusions formed at positions corresponding to the second holes (66A, 66B).

[0126] The tilting guide portion (60) may include an opening (60A) that corresponds to, opposes, or overlaps with the magnetic body (31) and / or the magnetic body (32). For example, the opening (60A) may correspond to, oppose, or overlap with the protrusion (28) of the sensor base (270). The opening (60A) may reduce the weight (or mass) of the tilting guide portion (60), thereby making the camera device (200) lighter. Additionally, the opening (60A) of the tilting guide portion (60) may be formed to avoid spatial interference with the magnetic body (31) and the protrusion (28) of the sensor base (270). The opening (60A) of the tilting guide portion (60) may be a through hole. The opening (60A) may penetrate the tilting guide portion (60) in a first direction (Z-axis direction) or an optical axis direction.

[0127] At least a portion of the protrusion (28) (or magnetic body (31)) of the sensor base (270) may be positioned within the opening (60A) of the tilting guide portion (60). For example, the protrusion (28) of the sensor base (270) may overlap with the opening (60A) of the tilting guide portion (60) in the direction of the optical axis. Additionally, for example, the protrusion (28) (or magnetic body (31)) of the sensor base (270) may overlap with the tilting guide portion (60) in a direction perpendicular to the direction of the optical axis. This allows the length or height of the camera device (200) in the direction of the optical axis to be reduced.

[0128] The tilting guide portion (60) may be an injection molded product. The tilting guide portion (60) may be made of plastic, resin, or ceramic material. In another embodiment, the tilting guide portion (60) may be made of a metal material, e.g., SUS material. Additionally, the tilting guide portion (60) may be a non-magnetic material. In another embodiment, the tilting guide portion (60) may be a magnetic material.

[0129] The first ball member (3A, 3B) may include two or more balls spaced apart in a direction parallel to the first axis or in the direction of the first axis. The second ball member (4A, 4B) may include two or more balls spaced apart in a direction parallel to the second axis or in the direction of the second axis. The arrangement direction (or arrangement direction) of the balls of the first ball member (3A, 3B) may intersect with the arrangement direction (or arrangement direction) of the balls of the second ball member (4A, 4B). For example, the arrangement direction (or arrangement direction) of the balls of the first ball member (3A, 3B) may be perpendicular to the arrangement direction (or arrangement direction) of the balls of the second ball member (4A, 4B). The OIS moving part (100) may rotate or tilt around the first axis by means of the first ball member (3A, 3B). And the OIS moving part (100) can be rotated or rotated axially or tilted around the second axis by means of the second ball member (4A, 4B).

[0130] In order to reduce friction and reduce power consumption, a lubricant may be placed in at least one of the groove (29) of the sensor base (270), the holes (65A, 65B) of the tilting guide part (60), the groove (55) of the base (210), and the holes (66A, 66B) of the tilting guide part (60).

[0131] The ball members (3A, 3B, 4A, 4B) may be members that perform rolling motion or sliding motion. The ball members (3A, 3B, 4A, 4B) may be expressed as "ball," "rolling member," "sliding member," or "ball bearing." Although the number of each of the first ball member and the second ball member is exemplified as two, in other embodiments, the number of each of the first ball member and the second ball member may be one or three or more.

[0132] The tilting guide portion (60) may be positioned below the image sensor (810). Additionally, at least a portion of the tilting guide portion (60) may overlap with the image sensor (810) in the optical axis direction. At least a portion of the tilting guide portion (60) may overlap with the lens module (400) (e.g., a lens) in the optical axis direction. At least a portion of the opening (60A) of the tilting guide portion (60) may overlap with the image sensor (810) in the optical axis direction. At least a portion of the opening (60A) of the tilting guide portion (60) may overlap with the lens module (400) in the optical axis direction. The first and second ball members (3A, 3B, 4A, 4B) may overlap with the image sensor (810) in the optical axis direction. The first and second ball members (3A, 3B, 4A, 4B) may overlap with the lens module (400) in the optical axis direction. Since the image sensor (810) is positioned on the upper side of the tilting guide portion (60), the size or placement of the image sensor (810) (or lens module (400)) may not be restricted by the shape or size of the tilting guide portion (60). Therefore, the embodiment can mount a large-aperture lens module (400), mount an image sensor (810) with a large size, and implement a camera device with ultra-high pixel resolution.

[0133] The support member may include a magnetic body (31) disposed on the OIS moving member (e.g., sensor base (270)) and a magnetic body (32) disposed on the fixed member (e.g., base (210)). The magnetic body (31) and the magnetic body (32) may be referred to as a "magnet," a "yoke," or a "holding magnet."

[0134] At least a portion of the magnetic body (31) may be placed within the opening (60A) of the tilting guide portion (60). The magnetic body (31) may face or overlap with the opening (60A) of the tilting guide portion (60) in the direction of the optical axis. The magnetic body (31) may not overlap with the tilting guide portion (60) in the direction of the optical axis. Additionally, at least a portion of the magnetic body (31) may overlap with the tilting guide portion (60) in a direction perpendicular to the optical axis. The magnetic body (32) may be a magnet. The magnetic body (32) may be placed below the magnetic body (31). The magnetic body (32) may be placed within the receiving portion (218) of the base (210). The magnetic body (32) may be placed on the fourth substrate (51) of the circuit board (250). The magnetic body (32) may be placed on the upper surface of the fourth substrate (51) of the circuit board (250). The magnetic body (32) may be coupled to the upper surface of the fourth substrate (51) of the circuit board (250). 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 opening (60A) of the tilting guide part (60) in the direction of the optical axis. The magnetic body (32) may not overlap with the tilting guide part (60) in the direction of the optical axis. The magnetic body (32) may not overlap with the tilting guide part (60) in a direction perpendicular to the optical axis. In another embodiment, the magnetic body (32) may overlap with the tilting guide part (60) in a direction perpendicular to the optical axis.

[0135] 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). The magnetic body (32) may be made of a material that adheres to the magnetic body (31). For example, the magnetic body (32) may be made of a metal material that adheres to a magnet. Or, for example, the magnetic body (32) may be made of a metal material that has magnetic properties. Or, for example, the magnetic body (32) may be a magnet. The magnetic body (32) may also be referred to as a "yoke."

[0136] Due to the attractive force between the magnetic body (32) and the magnetic body (31), the sensor base (270) and the base (210) can press the tilting guide part (60), and the tilting guide part (60) and the ball members (3A, 3B, 4A, 4B) can be in close contact with the sensor base (270) and the base (210). Due to the attractive force between the magnetic body (32) and the magnetic body (31), the tilting guide part (60) and the ball members (3A, 3B, 4A, 4B) can stably support the OIS moving part (100) with respect to the fixed part, and stable OIS operation can be performed. In addition, since at least a portion of the magnetic body (31) is placed within the opening (60A) of the tilting guide part (60), the distance between the magnetic body (31) and the magnetic body (32) can be reduced, and as a result, the attractive force between the magnetic body (31) and the magnetic body (32) can be increased, and the OIS moving part (100) can be stably supported by the fixed part.

[0137] FIG. 10 is a drawing for explaining the electromagnetic force (F1, F2, F3) and the movement of the tilting guide part (60) resulting from the interaction between the magnet units (130A to 130C) and the coil units (230A to 230C).

[0138] In the embodiment, for hand shake correction, the OIS drive unit may tilt the OIS moving unit (100) with respect to a first axis or a second axis, or rotate it within a preset angle range. The OIS drive unit may include a magnet (130) and a coil (230). The OIS drive unit may include a position sensor (240). The drive unit of the camera device (200) may include an AF drive unit and an OIS drive unit.

[0139] A first electromagnetic force (F1) may be generated by the interaction between the first magnet unit (130A) and the first coil unit (230A), and a second electromagnetic force (F2) may be generated by the interaction between the second magnet unit (130B) and the second coil unit (230B). The first electromagnetic force (F1) and the second electromagnetic force (F2) may act in an upward or downward direction. In other embodiments, the first and second electromagnetic forces may act in a direction different from the optical axis direction (e.g., a direction perpendicular to the optical axis direction). By the first and second electromagnetic forces (F1, F2), the OIS moving part may be tilted around the second axis (or ball members (4A, 4B)) or rotated within a preset angle range, which is defined as "second axis tilting."

[0140] Additionally, a third electromagnetic force (F3) may be generated by the interaction between the third magnet unit (130C) and the third coil unit (230C). The third electromagnetic force (F3) may act in an upward or downward direction. In another embodiment, the third electromagnetic force may act in a direction different from the optical axis direction (e.g., a direction perpendicular to the optical axis direction). By the third electromagnetic forces (F3), the OIS moving part may be tilted around the first axis (or ball members (3A, 3B)) or rotated within a preset angle range. In an embodiment, during hand shake correction or shake correction, the lens module (400) and the image sensor (810) may be simultaneously tilted along the X-axis or Y-axis by the same direction and the same angle, which is defined as "first axis tilting."

[0141] In a comparative example where a ball member is used to support the bobbin, a phenomenon may occur where the AF driving force caused by the interaction between the AF coil and the AF magnet affects the OIS operation, and as a result, the reliability of the OIS drive may be compromised. In the embodiment, since an elastic member (150, 160) is used to support the bobbin, the influence of the AF driving force on the OIS operation can be eliminated, thereby ensuring the reliability of the OIS operation.

[0142] The autofocus coil (120) and the OIS coil (230) may face each other or overlap in a direction perpendicular to the optical axis. For example, at the initial position of the bobbin (110), the coil (120) and the coil (230) may be arranged to face each other or overlap in a direction perpendicular to the optical axis (OA) and parallel to a straight line passing through the optical axis (OA). The initial position of the bobbin (110) may be the position of the bobbin (110) without applying power or a driving signal to the coil (120).

[0143] In the embodiment, the autofocus coil (120), the OIS coil (230), and the AF and OIS combined drive magnet (130) are arranged to overlap each other in a direction perpendicular to the optical axis, thereby reducing the size of the camera device (100) in the direction of the optical axis.

[0144] FIG. 11 is a top view of AF coil units (120A, 120B), magnet units (130A to 130C), and OIS coil units (230A, 230B, 230C); FIG. 12 is a side view of AF coil units (120A, 120B), magnet units (130A to 130C), and OIS coil units (230A, 230B, 230C); FIG. 13 is a side view of magnet units (130A, 130C) and coil unit (230C).

[0145] Referring to FIGS. 11 to 13, the autofocus coil unit (120A, 120B) and the OIS coil unit (230A, 230B) may be located opposite each other in the first axis direction (e.g., X-axis direction) with respect to the magnet unit (130A, 130B).

[0146] The magnet unit (130C) may be opposite to or overlap with the connecting line (120C) of the autofocus coil (120) in the second axis direction (e.g., the Y-axis direction). The magnet unit (130C) may not overlap with the coil units (120A, 120B) in the second axis direction. The connecting line (120C) may be placed on the side (110D) of the bobbin (110) that corresponds to, opposite to, or overlaps with the side (41D) of the housing (140) where the magnet unit is not placed.

[0147] Each of the first to third magnet units (130A to 130C) may be a 4-pole magnet comprising two N poles and two S poles. A 4-pole magnet may also be described as a "positively magnetized magnet."

[0148] Each of the first to third magnet units (130A to 130C) may include a first magnet part (11A, 12A, 13A), a second magnet part (11B, 12B, 13B), and a partition (11C, 12C, 13C) disposed between the first magnet part (11A, 12A, 13A) and the second magnet part (11B, 12B, 13B).

[0149] The first magnet section (11A, 12A, 13A) and the second magnet section (11B, 12B, 13B) may be spaced apart from each other in the direction of the optical axis. Each of the first magnet section (11A, 12A, 13A) and the second magnet section (11B, 12B, 13B) may include a North pole and a South pole. The first magnet section (11A, 12A, 13A) and the second magnet section (11B, 12B, 13B) may be arranged so that opposite polarities face each other in the direction of the optical axis. The partition (11C, 12C, 13C) separates or isolates the first magnet part (11A, 12A, 13A) and the second magnet part (11B, 12B, 13B), and may be a part that is substantially non-magnetic and has almost no polarity. The partition (11C, 12C, 13C) may be a non-magnetic material or air, etc. The partition (11C, 12C, 13C) may be described as a "Neutral Zone" or "Neutral Region".

[0150] Referring to FIG. 12, the length (H11, H21) in the optical axis direction of the coil units (120A, 120B) of the AF coil (120) may be smaller than the length (H12, H22) in the optical axis direction of the magnet units (130A, 130B) (H11, H21 < H12, H22).

[0151] The length (H13, H23) in the optical axis direction of the coil unit (230A, 230B) of the OIS coil (230) may be greater than the length (H12, H22) in the optical axis direction of the magnet unit (130A, 130B) (H13, H23 > H12, H22).

[0152] The length (H11, H21) in the optical axis direction of the coil unit (120A, 120B) of the AF coil (120) may be smaller than the length (H13, H23) in the optical axis direction of the coil unit (230A, 230B) of the OIS coil (230) (H11, H21 < H13, H23).

[0153] The number of turns in each coil unit (120A, 120B) of the AF coil (120) may be smaller than the number of turns in each coil unit (230A to 230C) of the OIS coil (230). This is because the weight of the OIS moving part is greater than the weight of the AF moving part. In another embodiment, the number of turns in each coil unit (120A, 120B) of the AF coil (120) and the number of turns in each coil unit (230A to 230C) of the OIS coil (230) may be the same.

[0154] The length (H31) of the magnet unit (130C) in the optical axis direction may be greater than the length (H12, H22) of the magnet unit (130A, 130B) in the optical axis direction (H31 > H12, H22). This can reduce the difference between the electromagnetic force for first-axis tilting (the sum of F1 and F2 in FIG. 10) and the electromagnetic force for second-axis tilting (F3 in FIG. 10), and improve the reliability of the OIS operation.

[0155] The lengths (H13, H23, H32) of the OIS coil units (230A, 230B, 203C) in the optical axis direction may be the same as each other. In another embodiment, the length (H32) of the coil unit (230C) in the optical axis direction may be greater than the lengths (H13, H23) of each of the coil units (230A, 230B) in the optical axis direction.

[0156] In another embodiment, in order to reduce the difference between the electromagnetic force for first-axis tilting (the sum of F1 and F2 in FIG. 10) and the electromagnetic force for second-axis tilting (F3 in FIG. 10), the length of the magnet unit (130C) in the first-axis direction may be greater than the length of the magnet unit (130A, 130B) in the second-axis direction. In yet another embodiment, the length of the coil unit (230C) in the first-axis direction may be greater than the length of the coil unit (230A, 230B) in the second-axis direction.

[0157] Referring to FIG. 13, the length (T1) in the optical axis direction of the first magnet part (11A, 12A) of the magnet unit (130A, 130B) may be smaller than the length (T2) in the optical axis direction of the second magnet part (11B, 12B) of the magnet unit (130A, 130B) (T1 < T2). The distance from the upper surface of the magnet unit (130A, 130B) to the partition wall (11C, 12C) may be smaller than the distance from the lower surface of the magnet unit (130A, 130B) to the partition wall (11C, 12C). The length (T3) in the optical axis direction of the partition wall (11C, 12C) of the magnet unit (130A, 130B) may be smaller than the length (T1) in the optical axis direction of the first magnet part (11A, 12A) of the magnet unit (130A, 130B) (T3 < T1).

[0158] As illustrated in FIG. 4a, in the embodiment, a filter (610) may be positioned adjacent to the bobbin (110) on the lower side of the bobbin (110). At the initial position of the bobbin (110), the partitions (11C, 12C) of the magnet units (130A, 130B) may face or overlap with the hollows (501, 502) of the coil units (120A, 120B). This is to improve the linearity regarding the correlation between the driving signal supplied to the AF coil (120) and the displacement of the bobbin (110).

[0159] Additionally, at the initial position of the OIS moving part, the hollow (503, 504) of the coil unit (230A, 230B) of the OIS coil (230) may face or overlap with the partition (11C, 12C) of the magnet unit (130A, 130B) in the first axial direction. The initial position of the OIS moving part may be the position of the OIS moving part when no power or driving signal is supplied to the coil units (230A to 230C) of the OIS coil (230). Additionally, at the initial position of the OIS moving part, the hollow (505) of the coil unit (230C) of the OIS coil (230) may face or overlap with the partition (13C) of the magnet unit (130C) in the second axial direction. This is to improve the linearity regarding the correlation between the driving signal supplied to the OIS coil (120) and the displacement of the OIS moving part.

[0160] In the initial position of the bobbin (110), the bobbin (110) can be driven to move in an upward or downward direction. As the initial position of the bobbin (110) is closer to the filter (610), the range of stroke in the downward direction of the bobbin (110) is restricted, and to avoid this restriction, the distance between the bobbin (110) and the filter (610) must be increased, thereby increasing the length in the optical axis direction of the camera device. This means that when the length in the optical axis direction of the coil units (120A, 120B) of the AF coil (120) is smaller than the length in the optical axis direction of the coil units (230A, 230B) of the OIS coil (230), the initial position of the bobbin (110) can be lowered further.

[0161] In the embodiment, since the length (T1) is shorter than the length (T2), the bulkhead (11C, 12C) can be positioned higher than the center (22A, 22B) of the magnet unit (130A, 130B), and the center of the hollow (501, 502) of the coil unit (120A, 120B) of the AF coil (120) at the initial position of the bobbin (110) can be designed to be higher than the center (22A, 22B) of the magnet unit (130A, 130B).

[0162] When compared to the position of the center of the hollow of the coil unit of the AF coil when the partition is located at the center of the magnet unit, in the embodiment, the center of the hollow (501, 502) of the coil unit (120A, 120B) of the coil (120) can be located higher, and the height of the camera device (200) can be prevented from increasing.

[0168] FIG. 14 shows magnet units (130A1 to 130C1) according to another embodiment, and FIG. 15 is a side view of the magnet units (130A1, 130C1) and coil unit (230C) of FIG. 14.

[0169] Referring to FIGS. 14 and 15, each of the magnet units (130A1 to 130C1) may be a two-pole magnet having one N pole and one S pole.

[0170] Each of the magnet units (130A1 to 130C1) may include a first magnet part (24A, 25A, 26A), a second magnet part (24B, 25B, 26B), and a partition wall (24C, 25C, 26C) between the first magnet part (24A, 25A, 26A) and the second magnet part (24B, 25B, 26B). The partition wall (24C, 25C, 26C) may be represented as a boundary surface or a boundary line.

[0171] The partitions (11C, 12C, 13C) of the four-pole magnet units (130A to 130C) of FIGS. 12 and 13 may be parts that are artificially formed when magnetizing the first magnet part (11A, 12A, 13A) and the second magnet part (11B, 12B, 13B). On the other hand, the partitions (24C, 25C, 26C) of FIGS. 14 and 15 may be parts that occur naturally to form a magnet consisting of one N pole and one S pole. The width of the partitions (11C, 12C, 13C) may be greater than the width of the partitions (24C, 25C, 26C). In this case, the width of the partition may be the length of the partition in the direction in which the first magnet part and the second magnet part face each other.

[0172] The first magnet part (24A, 25A, 26A) may include a first pole, and the second magnet part (24B, 25B, 26B) may include a second pole. The first pole may be an N pole or an S pole, and the second pole may have the opposite polarity of the first pole. The first magnet portion (24A, 25A, 26A) of FIGS. 14 and 15 may correspond to the first magnet portion of FIGS. 12 and 13, the second magnet portion (24B, 25B, 26B) of FIGS. 14 and 15 may correspond to the second magnet portion of FIGS. 12 and 13, the boundary surface (24C, 25C, 26C) of FIGS. 14 and 15 may be the partition wall of FIGS. 12 and 13, and the description of FIGS. 12 and 13 may be applied to or by analogy to the embodiment of FIGS. 14 and 15.

[0173] In a camera device according to another embodiment, the first magnet unit and the second magnet unit may be 4-pole magnets according to the embodiments of FIGS. 12 and 13, and the third magnet unit may be 2-pole magnets according to the embodiments of FIGS. 14 and 15. In yet another embodiment, the first magnet unit and the second magnet unit may be 2-pole magnets according to the embodiments of FIGS. 14 and 15, and the third magnet unit may be 4-pole magnets according to the embodiments of FIGS. 12 and 13. However, in the embodiments of FIGS. 12 and 13, since the magnet unit (130C) is a 4-pole magnet, the first and second magnet units (130A, 130B) are less affected by the magnetic field of the magnet unit (130C), so the influence of AF driving by the magnetic field of the third magnet unit (130) can be reduced, and thus the reliability of AF driving can be improved.

[0174] When two or more camera devices are placed adjacently in an optical device, magnetic field interference may occur between the driving magnet units mounted on the two adjacent camera devices, and such magnetic field interference may affect AF operation and OIS operation, and the reliability of AF operation and OIS operation may be reduced.

[0175] In the embodiment, since a driving magnet unit for OIS driving is not placed on one side (41D) of the housing (140), the optical device can be designed to prevent magnetic field interference between the driving magnet units of adjacent camera devices, thereby improving the reliability of AF operation and OIS operation.

[0176] In addition, in the embodiment, the connecting line (120C) connecting the AF coil units (120A, 120B) can be placed on the side (110D) of the bobbin (110) facing the side of the housing (140) where the magnet unit is not placed, and thus the design of the placement of the connecting line (120C) can be easily made, and spatial interference between the magnet unit and the connecting line can be easily avoided.

[0177] In addition, in the embodiment, the length of the first magnet part (11A, 12A) (or first pole) and the length of the second magnet part (11B, 12B) (or second pole) of the magnet units (130A and 130B, or 130A1 and 130B1) facing the coil units (120A, 120B) of the AF coil (120) and the coil units (230A, 230B) of the OIS coil (230) can be designed asymmetrically or differently from each other to prevent the length of the camera device (200) in the optical axis direction from increasing. The length of the first magnet part (11A, 12A) (or the first pole) in the optical axis direction is designed to be smaller than the length of the second magnet part (11B, 12B) (or the second pole) in the optical axis direction, thereby preventing an increase in the size of the camera device (200) in the optical axis direction according to the stroke range of the bobbin (110) in the optical axis direction.

[0178] 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 device, etc., but is not limited thereto, and any device for taking images or photos is possible.
