The first lens group 620 is contacted with the camera actuator 2000. This prevents damage to the lens group 620. For example, due to various factors, The components constituting the computer 2000 can be separated, and the separated components One of them may come into contact with the first lens group 620, causing a reliability problem. Therefore, the first stopper 660 prevents the first lens assembly 600 from being rotated. and the second camera actuator 2000, thereby The connection between the lens 2000 and the first lens assembly 600 (specifically, the first lens group 620) The first stopper 660 prevents damage to the first lens group 620. On the first surface of the first lens barrel 610, an opening 612h of the first lens barrel 610 The first stopper 661 and the first stopper 662 are arranged on both sides of the center. Including 62.
[0165] The second stopper 670 is provided between the first lens barrel 610 and the second lens assembly 610. 700, and restricts the movement of the second lens assembly 700 in the optical axis direction. For example, the second lens assembly 700 is aligned with the first rail of the first guide part 300. For example, the second lens assembly 700 moves along the first lens 310. a first optical axis direction toward the assembly 600 and a second optical axis direction toward the third lens assembly 800; The second stopper 670 moves in the two optical axis directions. The second stopper 670 can limit the movement of the front end 700 in the first optical axis direction. On the second surface of the first lens barrel 610, the aperture 612h of the first lens barrel 610 is centered, and includes a second-1 stopper 671 and a second-2 stopper 67 2 disposed on both sides thereof.

The first-2 portion 613-2 may be a first portion fitted to the first-1 portion 613-1. For example, the movement of the first stopper 661 in the horizontal direction can be limited. The stopper 613-2 can guide the mounting position of the first stopper 661. In this case, the first-second portion 613-2 can be mounted in the correct position with the first-first stopper 661. We can guide you to do so.

[0177] The first and second coupling recesses 615 and 616 have different shapes. Alternatively, the first and second coupling recesses 615 and 616 may be The first coupling recess 615 may have different sizes. The first coupling recess 616 may have a circular shape, and the second coupling recess 616 may have a square shape. This is not limited to this.
[0178] In an embodiment, the first coupling recess 615 and the second coupling recess 616 are different from each other. The second camera actuator 2000 is connected in reverse. That is, the first coupling recess 615 and the second coupling recess 616 are formed in a manner to solve the problem of the first coupling recess 615 and the second coupling recess 616 being ... second coupling recess 616 being formed in a manner to The second camera actuator and the mating recess 616 have different shapes. When the rotor 2000 is turned upside down, the coupling protrusion 2151 of the second housing 2100 This may result in the coupling 615, 616 between the 2152 and the coupling recess becoming impossible.
[0179] Meanwhile, the second surface of the first lens barrel 610 may include a second rib 630. The second rib 630 may have a shape corresponding to the first ribs 613, 614. The second stopper 670 is fitted to the second rib 630. 670 allows the movement of the second lens assembly 700 to be limited.
[0180] Meanwhile, the first lens assembly 600 may include a plurality of coupling holes.
[0181] The first lens assembly 600 includes a third coupling hole 640 and a fourth coupling hole 650. This can be done.
[0182] The third coupling hole 640 corresponds to the first coupling hole 340 of the first guide part 300. The third coupling hole 640 is connected to the first lens barrel of the first lens assembly 600. The third-1 coupling hole 641 and the third-2 coupling hole 642 are spaced apart from each other in the y-axis direction from one side of the bolt 610. The 3-1 coupling hole 641 and the 3-2 coupling hole 642 may include different For example, the third-first coupling hole 641 may be formed in a circular shape. The third-2 coupling hole 642 may be formed in an oval shape. For example, the center of the third coupling hole 640 may be aligned with the first coupling hole 340 in the optical axis direction. The third coupling hole 640 may be aligned with the center of the first coupling hole 340 in the optical axis direction. A protrusion of the base 100, which will be described later, can be inserted into the recess.
[0183] The fourth coupling hole 650 corresponds to the second coupling hole 440 of the second guide part 400. The fourth coupling hole 6500 is connected to the first lens bar of the first lens assembly 600. The 4-1 coupling hole 651 and the 4-2 coupling hole 652 are spaced apart from each other in the y-axis direction from the other side of the rail 610. The 4-1 coupling hole 651 and the 4-2 coupling hole 652 may include different For example, the 4-1 coupling hole 651 may have an oval shape. The fourth-second coupling hole 652 may be formed in a circular shape.

For example, the third coupling hole 640 may have a different shape. The -1 coupling hole 641 is circular and is spaced apart from the fourth coupling hole 650 adjacent in the x-axis direction. For example, the third coupling hole 642 of the third coupling hole 640 may be an oval. The fourth coupling hole 650 adjacent to the fourth coupling hole 650 in the x-axis direction has a circular shape. could be.

For example, the third coupling hole 640 may have the same shape. The -1 coupling hole 641 is circular, and the fourth-2 coupling hole 650 located diagonally thereto is The hole 652 may be circular. For example, the third-second coupling hole 642 of the third coupling hole 640 may be oval. The fourth coupling hole 650 is circular, and the fourth-1 coupling hole 651 located diagonally therebetween is elliptical. Here, the coupling holes having a circular shape are also called holes, and the coupling holes having an oval shape are called elongated holes. Also called a hole.
[0186] The circular holes, ie, the third-1 coupling hole 641 and the fourth-2 coupling hole 652, are formed on the first lens. When the first lens assembly 600 is coupled to the base 100, The base 100 can be firmly connected to the oval. The third-second coupling hole 642 and the fourth-first coupling hole 651 are elongated holes for the first lens assembly. When the 600 and the base 100 are joined, minute assembly tolerances that occur in the y-axis direction must be accommodated. This prevents rotation in the x-axis direction. The 3-2 coupling hole 642 and the 4-1 coupling hole 651 are connected to the 3-1 coupling hole 641 and the 4-2 coupling hole 652. Compared to the hole 652, it can have a shape that extends in the y-axis.

In addition, the diameter of the 3-2 coupling hole 642 and the 4-1 coupling hole 651 in the y-axis direction is The diameter of the 3-1 coupling hole 641 and the 4-2 coupling hole 652 in the y-axis direction is larger than that of the 3-1 coupling hole 641 and the 4-2 coupling hole 652. Good too.
