[0118] The blade portion (400) may include a first hole (403) into which the first protrusion (201) of the second fixed assembly (200) is inserted. The blade portion (400) may include a first hole (403) into which the first protrusion (201) of the second housing (210) is inserted.

The blade portion (400) can rotate and move linearly at the portion where it meets the second fixed assembly (200). The blade portion (400) can move linearly at the portion where it meets the moving assembly (300).

[0120] The blade portion (400) may include an escape groove (405) on a surface connected to the inner surface of the blade portion (400). The escape groove (405) may be an area for avoiding the second protrusion (313) of the magnet support member (310). The radius of curvature of the escape groove (405) may be greater than the radius of curvature of the second protrusion (313) of the magnet support member (310).

[0121] As the overlapping area of ​​the plurality of blades increases, the distance between the escape groove (405) of one of the adjacently arranged blades and the second hole (402) of the remaining blades may become closer. As the overlapping area of ​​the plurality of blades increases, the distance between the escape groove (405) of one of the adjacently arranged blades and the second protrusion (313) that engages with the remaining blades may become closer.

[0122] For example, the first blade (410) and the sixth blade (460) may overlap, and as the overlapping area of ​​the plurality of blades increases, the distance between the escape groove (405) of the first blade (410) and the first hole (403) of the sixth blade (460) may become closer. As the overlapping area of ​​the plurality of blades increases, the distance between the escape groove (405) of the first blade (410) and the first protrusion (201) that engages the first hole (401) of the sixth blade (460) may become closer.

[0123] The aperture device (1000) may include a hole (401). The blade portion (400) may include a hole (401) formed by a plurality of blade portions (400). The hole (401) may have a size or shape that can be changed by the plurality of blade portions (400). Light may pass through the hole (401).

[0124] The blade portion (400) may include a plurality of blades. The blade portion (400) may include first to sixth blades (410, 420, 430, 440, 450, 460). The first to sixth blades (410, 420, 430, 440, 450, 460) may have the same shape. At least one area of ​​the plurality of blades may be arranged to overlap in the optical axis direction. The plurality of blades may form a hole (401) whose size changes according to the movement of the moving assembly (300). As the overlapping area of ​​the plurality of blades increases, the size of the hole (401) may decrease. As the overlapping area of ​​the plurality of blades decreases, the size of the hole (401) may increase. The hole (401) may be formed by the inner peripheral surface (404) of the plurality of blades.

[0125] The plurality of blades can be arranged separately in two layers. The first to sixth blades (410, 420, 430, 440, 450, 460) can be arranged separately in two layers. The first blade (410), the third blade (430), and the fifth blade (450) can be arranged on the same plane in one layer. The second blade (420), the fourth blade (440), and the sixth blade (460) can be arranged on the same plane in one layer. The plurality of blades can be arranged in two layers, and the first blade (410), the third blade (430), and the fifth blade (450) can be arranged on the upper layer of the two layers, and the second blade (420), the fourth blade (440), and the sixth blade (460) can be arranged on the lower layer.

[0126] The first blade (410), the third blade (430), and the fifth blade (450) may not overlap due to the rotation of the magnet support member (310). When the opening formed by the first blade (410), the third blade (430), and the fifth blade (450) is at a minimum, the first blade (410), the third blade (430), and the fifth blade (450) may not overlap in the optical axis direction.

[0127] The second blade (420), the fourth blade (440), and the sixth blade (460) may not overlap due to the rotation of the magnet support member (310).

The inner surface (404) of the blade portion (400) may include a plurality of circular arc regions and an interpolation region formed between each of the plurality of circular arc regions.

[0129] When current is applied to the coil of the aperture device (1000), the blade unit (400) can move. That is, when current is applied to the coil of the aperture device (1000) and the moving assembly (300) moves, the shape of the hole (401) formed by the blade unit (400) can be changed. In other words, the F number of the aperture device (1000) can be changed by applying current to the coil.

[0130]

[0131] Below, the operation of the aperture device (1000) is described through FIGS. 20 to 22.

[0132] The center of the opening of the first fixed assembly (100) and the center of the opening of the second fixed assembly (200) may coincide with the optical axis (O). In the direction of the optical axis, the first tooth (122) and the second tooth (142) and the third tooth (222) and the fourth tooth (242) may not completely overlap. In the direction of the optical axis, the first tooth (122) and the second tooth (142) and the third tooth (222) and the fourth tooth (242) may be arranged to be misaligned.

[0133] The first tooth (122) and the second tooth (142) and the third tooth (222) and the fourth tooth (242) can be arranged to be rotated by 360 / N degrees (wherein, N can be the sum of the numbers of the first tooth (122) and the second tooth (142) or the sum of the numbers of the third tooth (222) and the fourth tooth (242)). When the sum of the numbers of the first tooth (122) and the second tooth (142) is 16, the first tooth (122) and the second tooth (142) and the third tooth (222) and the fourth tooth (242) can be arranged to be rotated by about 11.25 degrees (360 / 16 degrees).

[0134] In the optical axis direction, the first tooth (122) may be arranged to overlap with the third tooth (222) and the fourth tooth (242). In the optical axis direction, the second tooth (142) may be arranged to overlap with the third tooth (222) and the fourth tooth (242). In the optical axis direction, the third tooth (222) may be arranged to overlap with the first tooth (122) and the second tooth (142). In the optical axis direction, the fourth tooth (242) may be arranged to overlap with the first tooth (122) and the second tooth (142).

[0135] The angle (a) formed by the first virtual line (L1) that divides the first tooth (122) in half from the optical axis and the second virtual line (L2) that divides the third tooth (222) in half and the angle (b) formed by the third virtual line (L3) that divides the second tooth (142) in half from the optical axis and the fourth virtual line (L4) that divides the fourth tooth (242) in half may be the same. The angle (a) formed by the first virtual line (L1) that divides the first tooth (122) into two from the optical axis and the second virtual line (L2) that divides the third tooth (222) into two, and the angle (b) formed by the third virtual line (L3) that divides the second tooth (142) into two from the optical axis and the fourth virtual line (L4) that divides the fourth tooth (242) into two from the optical axis may be 360 / N degrees (wherein, N may be the sum of the numbers of the first tooth (122) and the second tooth (142) or the sum of the numbers of the third tooth (222) and the fourth tooth (242)).

[0136] In the initial state where no current is applied to the first coil (130) and the second coil (230), one magnet (320) can be arranged to completely overlap one third tooth (222) and one fourth tooth (242) in the optical axis direction. The circumferential width of one magnet (320) can be the same as the circumferential width from one third tooth (222) to one fourth tooth (242).

[0137] The magnet (320) may include an N pole region (321) and a S pole region (322) divided into two in the circumferential direction. The N pole region (321) of the magnet (320) may be arranged to overlap with the fourth tooth (242) in the optical axis direction. The S pole region (322) of the magnet (320) may be arranged to overlap with the third tooth (222) in the optical axis direction. The boundary between the N pole region (321) and the S pole region (322) of the magnet (320) in the optical axis direction may be arranged to overlap with one second tooth (142).

[0138] Referring to Fig. 22, when current is applied to the first coil (130), a magnetic field is formed in the first yoke (120) and the second yoke (140) according to Fleming's left-hand rule. For example, when current is applied clockwise to the first coil (130), a magnetic field is formed radially in the second tooth (142), and a magnetic field is formed inwardly of the first tooth (122) along the side plate (121) of the first yoke (120). Accordingly, the second tooth (142) has a south pole magnetism, and the first tooth (122) has a north pole magnetism.

[0139] At this time, when the first tooth (122) having the N pole magnetism faces the S pole region (322) of the magnet (320), an attractive force is generated between the first tooth (122) and the magnet (320). In addition, when the second tooth (142) having the S pole magnetism faces the N pole region (321) of the magnet (320), an attractive force is generated between the second tooth (142) and the magnet (320). Through this, when current is applied to the first coil (130), the magnet support member (310) can rotate.

[0140] The first coil (130) can receive current through the first connector assembly (150). The second coil (230) can receive current through the second connector assembly (250). The current applied to the first coil (130) and the current applied to the second coil (230) may have a phase difference. The current applied to the first coil (130) and the second coil (230) may be pulse currents. When a clockwise current is applied to the first coil (130), a counterclockwise current may be applied to the second coil (230). When a current is applied to the first coil (130), no current may be applied to the second coil (230). When current is applied to the second coil (230), current may not be applied to the first coil (130).

[0141] When current is applied to the first coil (130), the first yoke (120) and the second yoke (140) can become electromagnets. When current is applied to the first coil (130), the first yoke (120) and the second yoke (140) can become electromagnets having different polarities. When current is applied to the second coil (230), the third yoke (220) and the fourth yoke (240) can become electromagnets having different polarities. When current is applied to the second coil (230), the third yoke (220) and the fourth yoke (240) can become electromagnets having different polarities.

[0142] When a clockwise current flows through the first coil (130), the magnet support member (310) can rotate in the clockwise direction. In contrast, when a clockwise current flows through the first coil (130), the magnet support member (310) can rotate in the counterclockwise direction. When a clockwise current flows through the second coil (230), the magnet support member (310) can rotate in the clockwise direction. In contrast, when a counterclockwise current flows through the second coil (230), the magnet support member (310) can rotate in the counterclockwise direction.

[0143] When current is applied to the first coil (130) or the second coil (230), the magnet (320) can be driven to rotate by one step due to the repulsive force or attractive force of the yoke that has become an electromagnet. Here, one step can mean that when the sum of the first tooth (122) and the second tooth (142) is N, it rotates by 360 / N degrees. The magnet (320) can be maintained in a state aligned with the first to fourth yokes (120, 140, 220, 240) not only when current is not applied to the coil but also after the magnet support member (310) has rotated by one step.

[0144] This allows the magnets and yokes to be aligned in the correct positions, eliminating the need for separate alignment during assembly and enabling operation without a separate control system or sensor for coil position fixation and alignment. Furthermore, the number of magnet polarities and the number of yokes can be designed to match the blade drive steps for adjusting the aperture's light intensity, enabling precise operation. Furthermore, the current applied to the coil can be pulsed, minimizing power consumption.
