For example, the guide groove 55 may include an opening that opens to the upper surface of the housing 50. The guide groove 55 may be formed to be spaced apart from the groove 58 of the housing 50. For example, at least a portion 59 of the housing 50 may be disposed between the guide groove 55 and the groove 58.

For example, the guide groove 55 may include a chamfer shape or a step shape.

For example, a partition wall 59 may be disposed between the bottom surface of the guide groove 55 and the bottom surface of the groove 58. For example, the housing 50 includes a first partition 59A disposed between the bottom surface of the first guide groove 55A and the bottom surface of the groove 58A, and the bottom surface of the second guide groove 55B and the groove 58B. ) may include a second partition wall (59B) disposed between the bottom surfaces of the. The partition wall 59 may serve to prevent the rolling member 65 from leaving the groove 58 of the housing 50 and the groove 68 of the driving plate 61. In another embodiment, the partition wall 59 may be omitted, and the groove 58 and the guide groove 55 may be connected or communicate with each other.

For example, the thickness of the partition wall 59 or the distance between the bottom surface of the guide groove 55 and the bottom surface of the groove 58 may be smaller than the diameter of the rolling member 65. If this is greater than the thickness of the partition wall 59 or the distance between the bottom surface of the guide groove 55 and the bottom surface of the groove 58, the rolling member 65 is connected to the groove 58 of the housing 50 and the driving plate 61. This is because it may not be easy to insert it between the grooves 68 of ). In another embodiment, the guide groove 55 may be connected to or communicate with the groove 58 of the housing 50.

FIGS. 15A to 15D are diagrams for explaining the assembly sequence of the second actuator 320.

Referring to FIG. 15A, the elastic member 63 is coupled to the housing 50 to which the first substrate assembly is coupled. At this time, the “first substrate assembly” may be one in which the OIS coil 230, OIS position sensor 240, driver 260, and motion sensor 82 are coupled to or mounted on the first substrate portion 250.

The elastic member 63 is coupled to the housing 50. For example, one end of the elastic member 63 may be coupled to the groove 51 of the housing 50 using an adhesive.

Referring to FIG. 15B, the driving plate 61 is placed in the housing 50. For example, at least a portion of the protrusion of the housing 50 may be inserted or disposed within the opening 106 of the drive plate 61 .

Referring to FIG. 15B, the shortest distance between the first coil spring 63A and the second coil spring 63B may be smaller than the distance between the first guide groove 55A and the second guide groove 55B.

Also, for example, the shortest distance between the first coil spring 63A and the second coil spring 63B may be smaller than the distance between the third sensor 240C1 and the fourth sensor 240C2.

Also, for example, the separation distance between the third sensor 240C1 and the fourth sensor 240C2 may be smaller than the separation distance between the first guide groove 55A and the second guide groove 55B.

Also, for example, the separation distance between the third sensor 240C1 and the fourth sensor 240C2 may be smaller than the separation distance between the first ball member 65B1 and the second ball member 65B2.

Also, for example, referring to FIGS. 8A and 8B, the separation distance between the first protrusion 62B1 and the second protrusion 62B2 of the driving plate 61 is the distance between the first ball member 65B1 and the second ball member 675B2. It may be smaller than the separation distance.

Referring to FIG. 15C, the “holder assembly” is placed within the housing 50 so that the elastic member 63 is coupled to the holder 30. For example, the other end of the elastic member 63 may be coupled to the groove 37 of the holder 30 by adhesive.

Referring to FIG. 15D, the rolling member 65 is inserted and placed between the housing 50 and the driving plate 61.

When the rolling member 65 is pushed between the inner surface of the second side 28B of the housing 50 and the rear of the driving plate 61 along the guide groove 55, the rolling member 65 moves beyond the partition wall 59. It may be placed or seated in the groove 58 of the housing 50.

For example, the diameter of the rolling member 65 may be larger than the distance between the guide groove 55 and the rear surface of the driving plate 61. Also, for example, the diameter of the rolling member 65 may be larger than the distance (eg, the shortest distance) between the groove 68 of the driving plate 61 and the groove 58 of the housing 50. For example, the diameter of the rolling member 65 may be larger than the distance between the bottom of the groove 68 of the driving plate 61 and the bottom of the groove 58 of the housing 50.

When the rolling member 65 continues to move downward along the guide groove 55, the rolling member 65 crosses the partition wall 59 and passes through the groove 58 of the housing 50 and the groove 68 of the driving plate 61. ) can be seated or placed between. The partition wall 59 can prevent the rolling member 65 from leaving the groove 58 of the housing 50. The guide groove 55 can minimize damage to the elastic member 63 when assembling the rolling member 65 and can serve to prevent the elastic member 63 from being deformed.

The elastic member 63 may be stretched or expanded by the rolling member 65. The expanded elastic member 63 can generate an elastic restoring force to restore the original shape, and the “holder assembly” can be brought into close contact with the housing 50 by this elastic restoring force. That is, the holder assembly (for example, the holder 30) can press the driving plate 61 and the housing 50 by the elastic restoring force, and thus the holder assembly can be supported.

Figure 16 shows the arrangement of elastic units 63A and 63B according to another embodiment.

Referring to FIG. 16, the elastic member 63 may include a plurality of elastic units 63A and 63B. The plurality of elastic units 63A and 63B may be arranged to be spaced apart from each other in the second direction (X-axis direction). For example, the spacing between two neighboring elastic units may be the same. In Figure 16, the number of elastic units is 2, but in another embodiment, the number of elastic units may be 3 or more.

For example, in another embodiment, the housing 140 includes grooves in the form of a matrix having a plurality (e.g., two) rows and a plurality (e.g., two) columns formed in the protrusion 57A. It may be possible, and matrix-shaped elastic members corresponding to the matrix-shaped grooves may be provided.

Figure 17 shows the arrangement of another elastic member according to another embodiment.

Referring to FIG. 17, the elastic member 63 may include only one elastic unit 63A. For example, the elastic unit 63A may be located in the center or central area of the protrusion 57A of the housing 50. In another embodiment, the center of the elastic unit 63A may be arranged not to coincide with or be aligned with the center of the protrusion 57A.

Figure 18 is a cross-sectional view for explaining the relationship between the arrangement position of the elastic member 63 and the OIS driving force according to an embodiment.

12 and 18, the “holder assembly” may be supported on the housing 50 by the elastic member 63, and the first OIS magnets 31A and 31B and the first OIS coils 230A and 230B The holder assembly may be tilted about the first rotation axis 501 by the first electromagnetic force (F21, F22, F31, F32) caused by the interaction between the holder assembly.

The moment of the holder assembly is proportional to the separation distance between the source of the elastic restoring force and the source generating the electromagnetic force. For example, the source of elastic restoring force may be the elastic member 63, and the source of electromagnetic force may be the first OIS coils 230A and 230B.

When the separation distance between the elastic member 63 and the source generating the electromagnetic force increases, the magnitude of the first electromagnetic force can be reduced to obtain a preset moment value. Even with a small electromagnetic force, the holder assembly can be tilted around the first rotation axis 501, power consumption for OIS driving can be reduced, and OIS driving performance can be improved.

In order to increase the moment of this holder assembly, the embodiment has a structure in which the separation distance between the elastic member 63 and the first OIS coils 230A and 230B, which are sources of electromagnetic force, is increased.

For example, the elastic member 63 may be disposed closer to the first rotation axis 501 than to the first OIS coils 230A and 230B. For example, the separation distance between the elastic member 63 and the first rotation shaft 501 may be smaller than the separation distance between the elastic member 63 and the first OIS coils 230A and 230B.

For example, the elastic member 63 may be disposed closer to the center of the driving plate 61 than the first OIS coils 230A and 230B. For example, the separation distance between the elastic member 63 and the center of the driving plate 61 may be smaller than the separation distance between the elastic member 63 and the first OIS coils 230A and 230B.

For example, the elastic member 63 may be disposed closer to the center of the driving plate 61 rather than the edge or edge of the driving plate 61. For example, the separation distance between the elastic member 63 and the center of the driving plate 61 may be smaller than the separation distance between the edge or edge of the elastic member 63 and the driving plate 61.

In order to compare the separation distance on the YZ plane in FIG. 18, a straight line passing through the first rotation axis 501 and parallel to the first direction (Z-axis direction) is defined as the reference line 505. For example, the reference line 505 may be a straight line parallel to the direction from the second side 28B of the housing 50 toward the holder 30 and passing through the center of the driving plate 61. Alternatively, the reference line 505 may be a straight line parallel to the direction from the second side 28B of the housing 50 toward the holder 30 and passing through the center of the second side 28B of the housing 50. Alternatively, the reference line 505 may be a straight line parallel to the direction from the second side 28B of the housing 50 toward the driving plate 61 and passing through the center of the driving plate 61 . For example, the reference line 505 may be parallel to the optical axis (OA).

The elastic member 63 may be disposed closer to the reference line 505 than to the first OIS coils 230A and 230B. For example, the separation distance D1 between the elastic member 63 and the reference line 505 may be smaller than the separation distance D2 between the first OIS coils 230A and 230B and the reference line 505.

For example, D1 may be the distance between the reference line 505 and the center line of the elastic member 63. For example, the center line of the elastic member 63 may be a straight line parallel to the first direction and passing through the center of the elastic member 63 (see dotted lines on the left and right of the reference line shown in FIG. 18). In another embodiment, D1 may be the shortest separation distance between the reference line 505 and the elastic member 63.

For example, D2 may be the distance between the first OIS coils 230A and 230B and the center line of the elastic member 63. In another embodiment, D2 may be the shortest separation distance between the first OIS coils 230A and 230B and the elastic member 63.

Also, for example, the shortest distance between the first coil spring 63A and the second coil spring 63B may be smaller than the distance between the first coil spring 63A and the ball member 65B1.

Also, for example, the shortest distance between the first coil spring 63A and the second coil spring 63B may be smaller than the distance between the second coil spring 63B and the ball member 65B2.

Also, for example, the shortest distance between the first coil spring 63A and the second coil spring 63B may be smaller than the distance between the first ball member 65B1 and the second ball member 65B2.

The elastic member 63 may be disposed closer to the reference line 505 than to the third side 28C (or fourth side 28D) of the housing 50. For example, the separation distance between the elastic member 63 and the reference line 505 may be smaller than the separation distance between the third side 28C (or fourth side 28D) of the housing 50 and the reference line 505.

The elastic member 63 may be disposed closer to the center line of the housing 50 than to the third side 28C (or fourth side 28D) of the housing 50. The center line of the housing 50 may be a straight line parallel to the first direction (Z-axis direction) and having the same distance from each of the third side 28C and the fourth side 28D.

The elastic member 63 may be disposed closer to the reference line 505 than to the third side 31c (or fourth side 31d) of the holder 30. For example, the distance between the elastic member 63 and the reference line 505 may be smaller than the distance between the third side 31c (or fourth side 31d) of the holder 30 and the reference line 505.
