201110507 的工時。 如第7圖所示，將導通銷18a、18b和附連接器的導線 51焊接’接著將附連接器的導線51鉤掛在形成於外殼1〇 之導線鉤掛用的掛鉤30。藉此，即使附連接器的導線51 被粗暴地拉引，亦可加以保護，以避免焊接於驅動電路板 5 0之附連接器的導線5 1斷線。亦即，可防止因所焊接的 導線朝各方向被拉引而致使，接合位置疲乏而斷裂。 又，在外殻10形成有：可供***安裝於未圖示之相機 基板的光接收元件的***用凹部28、及將所完成之曝光條 件切換裝置安裝於未圖示之相機基板的凹孔29a、29b。 如第8圖所示，在激磁用線圈210被安裝於外殼10後， 藉由使激磁用的線圈端部211、212纒繞（捲繞）於導通銷 18a、18b並焊接，藉此，可確保激磁用線圈210對外部的 導通可靠性。 利用上述的組裝步驟完成搖動型電磁致動器。 因爲該曝光條件切換裝置係將曝光條件切換構件119 和虛擬濾光器120直接安裝於保持部1 10a，所以可簡化組 裝作業，並降低成本。 根據攝影機之功能的不同，亦有不須修正因曝光條件 切換構件119所引起之焦點偏移者，在使用於此種攝影機 的濾光器裝置中，亦可省略虛擬濾光器120。 上述實施形態中，係說明曝光條件切換裝置構成濾光 器裝置的例子，但是曝光條件切換裝置未限定爲切換2個 光學濾光器的濾光器裝置，亦可構成切換光之透過•遮蔽 -12- 201110507 的快門裝置或切換光圈之大小的光圈裝置。 構成快門裝置時，只要作成如第1圖〜第8圖所 光條件切換裝置中，省略曝光條件切換構件119及 光器120，同時如第9圖所示般，僅保持部110a的 l〇2a及***部102 b的一方具有貫穿孔之構成即可 作成***部l〇2a具有貫穿孔111a，而***部i〇2b 貫穿孔之構成即可。本例中，用以補償2個***部 102b之重量差的重物122被設置於***部l〇2a。 構成光圈裝置時，只要構成爲如第1圖〜第8圖 曝光條件切換裝置中，省略曝光條件切換構件119 濾光器1 2 0，同時貫穿孔1 1 1 a和貫穿孔1 1 1 b的直徑 異即可。例如，如第10圖所示，只要可構成爲貫穿 的直徑比貫穿孔1 1 1 b的直徑小即可。本例中，用以 個***部102a、102 b之重量差的重物122被設置於 102b，該***部102b具有直徑比貫穿孔111a的直 穿孔1 Π b。 具備有此光圈裝置的相機中，直徑較小的貫穿 被配置於光學開口 1 1、2 1之間的情況，與直徑較大 孔1 1 1 b被配置於光學開口 1 1、2 1之間的情況相比 的被拍攝物深度變深。即，可切換被拍攝物深度" 被拍攝物深度的切換可因應例如至被拍攝物之 遠近而進行。在被拍攝物較遠的情況，直徑較大的 111b被配置於光學開口 11、21之間，而在被拍攝物 情況，直徑較小的貫穿孔Π 1 a被配置於光學開口 示的曝 虛擬濾 ***部 。只要 未具有 10 2a、 所示的 及虛擬 彼此相 孔 1 1 1 a 丨補償2 ***部 徑的貫 孔 1 1 1 a 的貫穿 ，前者 距離的 貫穿孔 較近的 1 1、2 1 -13- 201110507 之間。藉此構成，可因應被拍攝物的遠近而進行良好的攝 影。 再者，亦可構成將光圈裝置和濾光器裝置組合的裝 置。構成這種裝置時’在如第1圖〜第8圖所示的曝光條件 切換裝置中，只要構成爲僅使貫穿孔111a和貫穿孔1Ub 的直徑彼此相異即可。例如，如第1 1圖所示，只要作成貫 穿孔11 1 a之直徑比貫穿孔1 1 1 b之直徑小的構成即可。本 例中，用以補償2個***部102a、102b之重量差的重物 122被設置於***部l〇2b，而該***部102b具有直徑比貫 穿孔111a之直徑大的貫穿孔111b。然而，亦可因應曝光條 件切換構件119和虛擬濾光器120的重量，將重物122設 置於***部l〇2a。 第11圖中，係將曝光條件切換構件119設置於具有直 徑較小之貫穿孔1 1 la的***部102a，並將虛擬濾光器120 設置於具有直徑較大之貫穿孔111b的***部102b，但是 亦可與此相反，如第12圖所示般，形成將虛擬濾光器120 設置於具有直徑較小之貫穿孔111a的***部102a，並將曝 光條件切換構件119設置於具有直徑較大之貫穿孔111b的 ***部102b之構成。 曝光條件切換構件1 1 9可列舉例如ND濾光器、IR截 止濾光器或組合有上述兩者的構成。但，並非限定爲此等 構成。 虛擬濾光器1 20亦可爲例如補償因曝光條件切換構件 119所引起之焦點偏移的濾光器。虛擬濾光器120亦可施 -14- 201110507 加防反射塗層。又，虛擬濾光器亦可依需要而省略。 如上所述，藉由組合曝光條件切換構件11 9和光圈的 大小，可因應各種.攝影環境。依此，在具備有此光圏、濾 光器組合裝置的相機中，可在各種的攝影環境下以良好的 條件進行攝影。 如上所述，因爲本實施形態的搖動型電磁致動器之可 動子的搖動軸係設置於被激磁用線圏圍繞之區域的外側， 所以可動子的安裝簡單，且因爲安裝於可動子之激磁用線 圈，係被捲繞成大致沿著被安裝於可動子之永久磁鐵搖動 的方向，所以可動子可在激磁用線圏內搖動。因此，可薄 型化、小型化，且可產生大的驅動力。 將該本發明之搖動型電磁致動器作爲驅動源使用的曝 光條件切換裝置，可薄型化、小型化，且組裝係容易。而 且，因爲搖動型電磁致動器具有大的驅動力，所以所應用 之曝光條件切換構件或虛擬濾光器不易受到限制。 此外，該實施形態係本發明之適合的實施例，本發明 未限定於如，亦可進行各種的變形。 【圖式簡單說明】 第1圖係表示本發明之適合的實施形態之曝光條件切 換裝置的構成圖。 第2圖係表示本發明之適合的實施形態之曝光條件切 換裝置的構成圖。 第3圖係表示本發明之適合的實施形態之曝光條件切 換裝置的構成圖。 -15- 201110507 第4圖係表示曝光條件切換構件之安裝方法圖。 第5圖係表示虛擬濾光器之安裝方法圖。 第6圖係表示以壓板保持曝光條件切換構件及虛擬濾 光器之狀態圖。 第7圖係表示將附連接器的導線鉤掛在形成於外殼之 導線鉤掛用的掛鉤之狀態圖。 第8圖係表示使激磁用線圈端部纒繞在導通銷並焊接 之狀態圖。 第9圖係表示僅***部之一方具有貫穿孔的構成圖。 第1〇圖係表示一方之***部之貫穿孔的直徑比另一 方之***部的貫穿孔的直徑小的構成圖。 第 Π圖係表示虛擬濾光器被設置於具有小直徑之貫 穿孔的***部，而曝光條件切換構件被設置於具有大直徑 之貫穿孔的***部之構成圖。 第12圖係表示虛擬濾光器被設置於具有小直徑之貫 穿孔的***部，而曝光條件切換構件被設置於具有大直徑 之貫穿孔的***部之構成圖。 第13圖係表示習知之搖動型電磁致動器的構成圖。 【元件符號說明】 10 外殼 11 開口部 12a、12b 安裝部 13 搖動承軸 14 ' 24 、 118 肋 -16 -

[Prior Art] A small camera (static camera, camera, surveillance camera, etc.) can be loaded on a notebook PC, a mobile phone terminal, or a car. The drive source of the exposure condition switching device such as the shutter device, the aperture device, or the filter device provided in the camera is often configured to rotate in a predetermined angular range. This type of actuator is composed of the following members, etc., comprising: a rotor having a cylindrical permanent magnet and having a drive pin at a position eccentric from the center of rotation; the frame member rotatably supporting the rotor: The excitation coil is wound around the outside of the frame member, and the yoke is fitted into the outer periphery of the frame member. In this configuration, the exciting coil is wound around the outside of the frame member, and is generally wound around a rotating shaft surrounding the rotor. Therefore, the size of the rotor in the direction of the rotation axis becomes large, and as a result, the thickness of the exposure condition switching device such as the diaphragm device becomes thick. When the thickness of the exposure condition switching device is increased, it is difficult to reduce the thickness or size of the camera equipped with the exposure condition switching device. As an invention relating to an electromagnetic actuator that has been reduced in thickness, there is a "shear actuator for an electromagnetic actuator and a camera" disclosed in Patent Document 1. The invention disclosed in Patent Document 1 is an actuator in the form of an output driving force having a 201110507 device: a movable member 400 for loading a permanent magnet 401 on a free end, and having a driving pin 402 on a front end side of the free end; 410 is wound around the bobbin 412; and the stator 420 is a yoke 42 including the outer side in the thickness direction of the exciting coil of the magnetic path, and the exciting coil 410 is energized to shake the movable member 400, by driving Output drive force. In the invention of Patent Document 1, the point 403 of the movable member 400 is disposed in a region surrounded by the exciting coil 410, and the movable member 400 is rocked outside the region surrounded by the exciting wire. The fulcrum 403 is centered so that the area surrounded by the exciting coil 410 of the movable member 400 is thin and flat. Therefore, the structure in which the coil is wound around the rotor can be made thinner. [Problem to be Solved by the Invention] The electromagnetic actuator shown in Fig. 13 is obtained by winding a coil for excitation in a cylindrical shape. Since the bobbin 412 is disposed in the thickness direction and the rocking bearing of the movable member is disposed in the yoke, it is made thinner. The present invention has been made in view of the above problems, and an object of the invention is to provide an electromagnetic system capable of generating a large driving force and an exposure condition switching device including the electromagnetic actuator. [Means for Solving the Problem] In order to achieve the object, the first aspect of the present invention is such that the center coil of the lifting side is placed in a shape, and the side of the bucket is swung by the pin 410. The ring 410 can be compared to the outer side of the body, and the outer ring is provided with a limiter for the 201110507 rocking type electromagnetic actuator, which has a casing and an upper cover, and is rotatably supported by the outer casing and the upper cover. The movable element and the excitation coil fixed to the outer casing and the yoke for forming the magnetic circuit, and the movable element is rocked by the energization of the excitation coil, and the movable electromagnetic actuator is characterized in that the movable member has the first (1) the exposure portion and the second exposure portion are pivoted by a shaft and a bearing hole provided on an outer side of the region surrounded by the excitation coil and the upper cover; the excitation coil surrounds the permanent magnet of the movable member, and The planes of the permanent magnets are crossed while being wound into substantially along the plane. In order to achieve the object, the present invention provides an exposure condition switching device according to the first aspect of the present invention, characterized in that the swing type electromagnetic actuator according to the first aspect of the present invention is configured to shake the movable member. The exposure conditions of the exposure opening formed in the outer casing and the upper cover are switched. [Effect of the Invention] According to the present invention, it is possible to provide an electromagnetic actuator which can be made thinner and smaller, and which can generate a large driving force, and an exposure condition switching device including the electromagnetic actuator. [Embodiment] A suitable embodiment of the present invention will be described. Fig. 1 shows the configuration of an exposure condition switching device of the present embodiment. This exposure condition switching device is for a camera, and is provided with a swing type electromagnetic actuator as a drive source. Further, Fig. 2 is an overall view showing an assembled state of the exposure condition switching device, and Fig. 3 is a cross-sectional side view showing an assembled state. As shown in Fig. 1, the movable member 100 is formed such that the holding portions 110a and 110b are opposed to each other with the rocking shaft 112 interposed therebetween. The exposure condition switching member 119 and the virtual t--b] 5 201110507 The pseudo filter 120 is attached to the holding portion 110a side by the pressing plate 121, and the permanent magnet 1 14 is attached to the holding portion 1 10b side. Further, the movable member 100 is attached to the rocking bearing shaft 13 provided in the outer casing 10, and the rib 14 is formed around the opening portion 11 for exposure which is provided in a circular portion in the central portion of the outer casing 1A. The movable member 1 of the rocker 13 is slid smoothly. Further, the magnet 200 and the yoke 220 constituting the magnetic circuit are attached to the casing 10 to constitute the stator 200, and the movable portion 100 and the stator 200 constitute the driving portion 300. As the exciting coil 210, by using an air core wire formed by welding the electric wires by heat or the like, the winding frame can be eliminated, and the stator 200 can be made thin. Further, the permanent magnet 114 is formed to be rotatable in the exciting coil 210, and the yoke 220 constituting the magnetic path is also disposed outside the exciting coil 210 in the rocking direction of the movable member 100, and the stator 200 can be thinned and driven. The portion 300 is thinned as a whole. Further, since the frame for winding does not exist, the distance between the permanent magnet 114 of the movable member 100 and the exciting coil 210 is shortened, and the permanent magnet 114 strongly acts on the magnetic force of the exciting coil 210 to increase the driving force. Therefore, the drive unit 300 which is thin and has a strong driving force can be constructed. Further, the lead 51 and the drive circuit board 50, which are connected to the power supply connector of the power source, are fixed to the back surface of the casing 10 by screws 52. In the upper cover 20, a rocking bearing hole 22 for supporting the rocking shaft 112 of the movable member 1 is provided. Further, in the central portion of the upper cover 20, the exposure opening portion 21 is formed in a circular shape, and a rib 24 for allowing the 201110507 movable member 100 to smoothly slide is provided on the side (not shown) on the periphery thereof. Further, in the upper cover 20, guide holes 25a, 25b for locating the guide pins 15a, 15b of the outer casing 10 are provided, and the exposure opening portion 21 and the rocking bearing hole 22 of the upper cover 20 are provided. The positional accuracy of the opening portion 11 of the 10 and the rocking bearing shaft 13. The upper cover 20 and the outer casing 10 are fixed by screwing the screws 23a to 23c through the screw through holes 26a to 26c of the upper cover 20 to the screws 16a to 16c of the outer casing 10. As shown in Fig. 2, after the movable member 100 is attached to the bearing shaft 13 of the casing 10, the exciting coil 210 is slid and inserted into the rocking coil mounting portions 12a and 12b of the casing 10, and pushed into the excitation. Mounted by the coil stoppers 17a and 17b. Next, the projections 221 formed by the yokes 220 constituting the magnetic circuit are inserted into the yoke insertion recesses 27a and 27b formed in the outer casing 10, and mounted thereon to constitute the stator 200. Further, the excitation coils abut against the stoppers 17a and 17b, and have projections 19a and 19b which are stoppers for restricting the movement of the movable member 100 by the holding portions 11 and 19b. By simply attaching the movable member to the rocking fulcrum 13 of the casing 10, the shaking of the movable member 1 toward the direction Fa and the arrow Fb can be restricted. As shown in FIG. 2 and FIG. 3, the exposure condition switching member 119 is attached to the exposure 111a on the side of the holding portion 1 1 0 a on the side of the exposure opening portion 1 1 which is closer to 10 than the pan axis 112, and is exposed. The dummy filter 120 is mounted with the hole u. Insert the meter into the outer casing and place it in the wire hole to form a rocker against the 222. By the side shape 3a, the 100-direction arrow housing hole 1b side 201110507 can be formed in the form of a member by directly attaching the exposure condition switching member 119 of the camera to the holding portion 110a of the exposure opening portion 11 of the outer casing 10. Mounted on the housing's rocking axle, it simplifies assembly and reduces costs. In visible light and near-infrared light, the refractive index differs depending on the wavelength region. Therefore, when the camera is used in the visible light region during the daytime and when the camera is used in the near-infrared light region during the nighttime, the focus moves due to the optical relationship, and in order to correct it, a virtual filter for correcting the movement of the focus is required. Device. Therefore, the exposure condition switching member 119 is attached to the exposure hole Ilia side of the holding portion 1a, and the dummy filter 120 is attached to the exposure hole 1 1 1 b side to perform day and night imaging. The visible light exposure condition switching member 119 is integrally attached to the holding portion 11A located on the exposure opening portion 11 side of the casing 10, and the near-infrared light dummy filter is integrally attached to the holding portion Π Ob. The integrated member performs switching using either of the exposure condition switching member 119 and the dummy filter 120. Further, by attaching the movable member 1 to the rocking cap 13 formed in the outer casing 10, the assembly work can be simplified, and the cost can be reduced. On the side of the holding portion 110b of the movable member 100 on the side of the exciting coil 210, a permanent magnet 114 that has been magnetized in the rocking direction is attached to a plane including the rocking direction of the movable member 100, and can be shaken in the exciting coil 210. . Since the exciting coil 210 that is oscillated by the permanent magnet 114 is an air core, and the distance between the permanent magnet 114 and the inner side of the exciting coil 210 is relatively short, the magnetic force of the permanent magnet 114 on the coil 210 is increased, and the driving is increased. The power will increase. Further, the holding portion 110b is provided with a rib 118 to which the permanent magnet 114 is inserted, and the rib 118 of the holding portion iib is inserted into the permanent magnet 114 so as not to be detached. The yoke 220 formed on the outer side of the exciting coil 210 in the direction in which the movable element 100 is rocked forms a magnetic path with the permanent magnet 1 14, and the movable member 100 can be held by the yoke 220 and cut off. The rocking position of the exciting coil 210 when energized. Therefore, the movable member 100 can be held even if the excitation coil 210 is not energized, and power can be saved during this period. Further, the exciting coil 210 attached to the side closer to the holding portion 11b than the rocking shaft 112 of the movable member 1 surrounds the permanent magnet 114 and swings it. As shown in Fig. 4, the exposure condition switching member 1 1.9 is attached to the holding portion 111a by being hooked into the hooks 115a to 115ci of the holding portion 110a in the direction of the arrow Ya. Further, as shown in Fig. 5, the dummy filter 120 is attached by being attached to the hooks 116a to 116d of the holding portion 11a by sliding in the direction of the arrow Yb. In order to prevent the exposure condition switching member 119 and the dummy filter 120 attached to the insertion of the holding portion 110a from being detached, the pressing plate 121 of the elastic material is inserted into the hooks 117a and 117b of the holding portion U〇a while being bent. As shown in Fig. 6, the pressing plate 121 of the elastic material is inserted into the hooks 117a, 117b and spring-backed by the elastic force to be fitted to the hooks H7a, 117b. In this manner, the exposure condition switching member 119 and the dummy filter 120 can be mounted without using a binder, so that the number of man-hours during the installation operation -11 - 201110507 can be reduced. As shown in Fig. 7, the conductive pins 18a, 18b and the wires 51 attached to the connector are soldered'. Then, the wire 51 attached to the connector is hooked to the hook 30 for wire hooking formed in the outer casing 1''. Thereby, even if the wire 51 attached to the connector is violently pulled, it can be protected to prevent the wire 5 1 soldered to the connector of the drive circuit board 50 from being broken. That is, it is possible to prevent the welded wire from being pulled in all directions, and the joint position is fatigued and broken. Further, the housing 10 is formed with an insertion recess 28 for inserting a light receiving element mounted on a camera substrate (not shown), and a recess 29a for attaching the completed exposure condition switching device to a camera substrate (not shown). 29b. As shown in Fig. 8, after the exciting coil 210 is attached to the casing 10, the coil ends 211 and 212 for exciting are wound (wound) around the conducting pins 18a and 18b and welded. The conduction reliability of the excitation coil 210 to the outside is ensured. The rocking type electromagnetic actuator is completed by the assembly steps described above. Since the exposure condition switching device directly mounts the exposure condition switching member 119 and the dummy filter 120 to the holding portion 110a, the assembly work can be simplified and the cost can be reduced. Depending on the function of the camera, there is no need to correct the focus shift caused by the exposure condition switching member 119. In the filter device used in such a camera, the dummy filter 120 may be omitted. In the above embodiment, an example in which the exposure condition switching device constitutes the filter device will be described. However, the exposure condition switching device is not limited to the filter device that switches the two optical filters, and may constitute the transmission/shielding of the switching light. 12-201110507 Shutter device or aperture device that switches the size of the aperture. In the case of the shutter device, the exposure condition switching member 119 and the optical device 120 are omitted in the light condition switching device as shown in Figs. 1 to 8 , and as shown in Fig. 9, only the holding portion 110a is closed. Further, one of the insertion portions 102b may have a through hole, and the insertion portion 102a may have a through hole 111a, and the insertion portion i2b may have a through hole. In this example, the weight 122 for compensating for the weight difference between the two insertion portions 102b is provided in the insertion portion 10a. When the aperture device is configured, the exposure condition switching member 119 filter 1 120 is omitted, and the through hole 1 1 1 a and the through hole 1 1 1 b are omitted as long as the exposure condition switching device is configured as shown in Figs. 1 to 8 . The diameter is different. For example, as shown in Fig. 10, the diameter that can be formed to penetrate is smaller than the diameter of the through hole 1 1 1 b. In the present example, the weight 122 for the difference in weight between the insertion portions 102a, 102b is provided at 102b, and the insertion portion 102b has a straight perforation 1 Π b having a diameter larger than that of the through hole 111a. In a camera having such an aperture device, a small diameter through hole is disposed between the optical openings 1 1 and 2 1 , and a larger diameter hole 1 1 1 b is disposed between the optical openings 1 1 and 2 1 The depth of the subject is deeper than in the case of the subject. That is, the switchable subject depth " the depth of the subject can be switched depending on, for example, the distance to the subject. In the case where the subject is far away, the larger diameter 111b is disposed between the optical openings 11, 21, and in the case of the subject, the smaller diameter through hole Π 1 a is disposed in the optical opening. Filter the insertion section. As long as there is no penetration of the through hole 1 1 1 a of the insertion hole diameter of 10 2a, the virtual phase hole 1 1 1 a 丨 compensation, the penetration distance of the former is relatively close to the 1 1 , 2 1 -13- Between 201110507. With this configuration, it is possible to take good pictures in accordance with the distance of the subject. Further, a device in which the aperture device and the filter device are combined may be constructed. In the case of constituting such a device, the exposure condition switching device shown in Figs. 1 to 8 may be configured such that only the diameters of the through hole 111a and the through hole 1Ub are different from each other. For example, as shown in Fig. 1, it is sufficient that the diameter of the through hole 11 1 a is smaller than the diameter of the through hole 1 1 1 b. In this example, the weight 122 for compensating for the weight difference between the two insertion portions 102a, 102b is provided in the insertion portion 102b, and the insertion portion 102b has a through hole 111b having a diameter larger than the diameter of the through hole 111a. However, the weight 122 may be placed in the insertion portion 10a2a in accordance with the weight of the exposure condition switching member 119 and the virtual filter 120. In Fig. 11, the exposure condition switching member 119 is placed in the insertion portion 102a having the through hole 1 1 la having a small diameter, and the dummy filter 120 is placed in the insertion portion 102b having the through hole 111b having a large diameter. However, in contrast to this, as shown in FIG. 12, the insertion portion 102a having the dummy filter 120 provided in the through hole 111a having a small diameter is formed, and the exposure condition switching member 119 is set to have a diameter. The configuration of the insertion portion 102b of the large through hole 111b. The exposure condition switching member 1 1 9 may be, for example, an ND filter, an IR cut filter, or a combination of the above. However, it is not limited to this composition. The dummy filter 120 may also be, for example, a filter that compensates for a focus shift caused by the exposure condition switching member 119. The dummy filter 120 can also be applied with an anti-reflection coating of -14-201110507. Also, the dummy filter can be omitted as needed. As described above, by combining the exposure condition switching member 119 and the size of the aperture, it is possible to cope with various photographic environments. According to this, in the camera equipped with the optical pickup and the filter combination device, photography can be performed under good conditions in various imaging environments. As described above, since the swing axis of the movable member of the swing type electromagnetic actuator of the present embodiment is disposed outside the region surrounded by the field for the excitation, the movable member is easily mounted and is excited by the movable member. The coil is wound in a direction substantially along the direction in which the permanent magnet attached to the movable member is rocked, so that the movable member can be rocked in the field for the excitation. Therefore, it can be made thinner and smaller, and a large driving force can be generated. The exposure condition switching device used as the driving source of the rocking type electromagnetic actuator of the present invention can be made thinner and smaller, and the assembly system is easy. Moreover, since the shaking type electromagnetic actuator has a large driving force, the applied exposure condition switching member or the dummy filter is not easily limited. Further, this embodiment is a suitable embodiment of the present invention, and the present invention is not limited to, and various modifications can be made.
