Description of the Invention: [Technical Field] The present invention relates to a lens fixing unit for photographing and a photographing apparatus comprising the lens fixing unit. [Prior Art 0 In recent years, small-sized camera devices have been mounted on various devices such as notebook PCs, mobile phones, vehicles, and surveillance devices. Such a photographic apparatus includes a lens and a photographic element, and is configured by arranging an optical element such as a filter or an iris (aperture) on a light path between the boring head and the photographic element as needed. In the case of the lens, a housing main body (hereinafter simply referred to as a "camera main body") for a camera device having an optical element or the like is mounted by using a lens fixing unit (for example, Japanese Patent Literature 1). The casing body of the photographic apparatus (hereinafter referred to as Document 1). In the case of the lens fixing unit, there is a member in which a male screw portion is provided on the side of the lens unit holding the lens, and a meat screwed to the external thread portion is provided on the side of the holder unit attached to the camera body. For the screw portion, the fixing of both the lens unit and the holder unit is performed by screwing the two portions. For example, refer to Patent Document 1). In the lens fixing unit of such a configuration, the focus adjustment of the lens is performed by the degree of locking of the internal thread portion by Qiu. The "corner state is rotated and fine-tuned" so that the focus of the lens "head (2); the direction perpendicular to the direction" is from the position of the axis of the single-threaded portion relative to the holder unit. In other words, the lens unit [the prior art document] is fixed (for example, refer to Patent Document 2). [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. Since the position of the lens unit is fixed at the front end of the fixing screw, it is necessary to first set the screw-through hole in the solid state, so that the following head 2 is produced, and the L-fixing hole is the through-hole structure. The timing will be directly contacted before the timing 'setting screw' =. Therefore, depending on the degree of locking of the fixing screw, there is a possibility that foreign matter such as dust or dust is generated from the direct contact. When such an difference is made, the result of the photographing of the photographic element is caused to be defective, and the generation of the foreign matter is prevented. L1 should be a little more about the holding frame. It can be considered to be made by the die-casting process. In the case where the hole for the screw is used =: = the structure is found, it is very difficult to set the through J by the molding process. In order to prevent the inner peripheral side of the internal thread portion from being broken, the through hole is opened after the molding process is performed to open the through hole.

Detailed configuration of the lens fixing unit> 201219874 The lens fixing unit 20 in the photographic apparatus of the embodiment 30, 牛八虹Wood further elaborates on its special composition. As explained above, as the pound 萠 light condition cutting element master money; can face one type of exposure as s i and the system and the second number. Here, a description will be given of a two-sided example. First, the third specific example is changed. (2. 1. First specific example) In the first specific example, an example of a second type lens fixing unit for a camera device is described. FIG. 5 is a perspective view showing a schematic configuration of a first specific example of the display unit, FIG. 5 is a second embodiment of the lens fixing unit, and FIG. 6 is a second side of the lens fixing unit. A three-sided picture of the composition. As shown in FIG. 4 or FIG. 5, the first and the sculpt unit 250B and the holder of the holder /2 single limb case include a lens. Box 27. : The lower end forms: - body and is attached to the mirror. The external thread portion is threaded. On the other hand, the holder unit 200B has a shape and a second portion 21a, and is formed in the lens unit mounting portion 21? Moreover, the circle of the lens unit skirting unit 210 is allowed. The inner screw of the outer flange portion 270 of the flange frame 270 is screwed to the % lens. Since the external thread portion 2T2 is screwed, the diameter and pitch of the outer screw portion are, for example, Μ12χ〇.5. ', ^ 72 is the same, nominally, for the lens unit 250B, the threading portion 272 and the internal thread portion 221 are screwed together to move A: by the optical axis direction of the external screw lens 271 Let the single Z along the = direction in the "optical axis direction" referred to herein along the mirror 201219874, and for the holder unit 2〇〇b, by inserting the screw 216 through the threaded insertion hole 213' of the flange 215. The screw 216 is locked into the threaded hole inside the face casing 110 after the exposure condition switching unit main body 10, and the holder unit 2B is fixed in front of the casing 1〇1 of the exposure condition switching unit main body 1〇. side. Therefore, the focus adjustment of the lens 271 in the lens unit το 250B can be performed by adjusting the degree of locking of the male screw portion 272 with respect to the female screw portion 221 in a state where the holder unit 200B is fixed to the front side of the casing 101. That is, the splicing state of the external thread portion 272 and the internal thread portion 221 can be finely adjusted, and the focus of the lens 271 can be aligned with the photographic element in the photographic element unit 〇37〇8〇8〇8. On the 370B. & ^ and after the focus adjustment of the lens 271 is performed, it is necessary to maintain the state. This is because in many cases, it is not necessary to perform focus adjustment again in the case of a CCTV camera or the like. Further, in addition, after the telecentricity is completed, if the state of the external thread portion 272 and the female screw portion 221 is changed to shift the focus position of the lens π, a good photographing result cannot be obtained. - For this reason, the mirror-fixing unit 2Q includes a fixing screw 29A in addition to the _ unit 2^ and π200Β. The fixing screw system/the outside of the cylinder is turned into the cylinder, and is used to fix the position of the lens in the cylinder of the lens. Further, the lens unit mounting portion 21 of the holder frame is placed at 200 〇, and the mounting hole is fixed by "the screw 29〇' along the optical axis of the lens 271, in the direction of the parent fork. However, the lens unit mounting portion 21 ^ ^ ^ ^ ^ However, as shown in Fig. 6, the mounting hole is a non-through hole 23 in the cylinder that is not penetrated; 210. The mounting hole of the fixing screw 290 is a non-transparent unit mounting portion, and the non-through hole 231 is formed on the inner surface of the lens of the lens unit 210 (that is, the screw portion of the female screw portion 221 is an interposed portion 232). The clamping portion 232 is formed as follows: the wall through hole 231 _ the front end of the fixed screw 290 is pressed, and the depth of the thickness of the tube is set to 211 2012: Zt^l 13 201219874 The depth of the sand required for the person @定螺丝29Q as the formation depth of the non-j, can be considered in the lens unit mounting portion 21〇

The lens unit 250C has a lens frame 280 for holding the lens 281. And a male screw portion 282 formed at a lower end of the lens frame 280. The diameter of the member is formed larger than in the first specific example. Specifically, the external thread portion 272 is different from the first specific example. The nominal diameter and pitch are, for example, M12x〇.5, and the external thread portion 282 in the second embodiment is, for example, 25.4 mm (1 inch) in inner diameter and 螺_794 mm (32 teeth/inch) in pitch. The threaded portion corresponding to the C-Mount standard. On the other hand, the holder unit 200C There is a lens unit mounting portion 240 that forms a cylindrical shape, and a flange 16 that is formed at an end portion of the lens unit mounting portion 24〇. 201219874 1 The specific holding frame unit 2_ is formed into a convex shape = a holding in the example The frame unit 2Q0C is connected to the housing of the large cylinder _^, the unit 240 ί® 280 :, ; --j, and the housing of the housing unit 10 of the exposure condition switching unit 10 In the example, the lens is mounted on the lens of the holder unit by the external thread portion 282 and the internal thread portion; and, in addition, the lens fixing unit 20 includes the lens unit 2〇〇c The fixing screw 29 is only =. 2 The holder and the holder of the head unit are turned into the cylinder outside the cylinder.

The intervening portion 232 is formed to have a thickness such that the front end of the fixing screw 290 which is pinned by the wall is pressed, and the inside of the cylinder is not deformed by the inside of the through hole 231. That is, the head unit mounting portion 17 201219874 The lens unit 25 () C has a large diameter. Therefore, the non-through hole 231 can take into consideration the plural portions of the unit mounting portion. As the plural, there are two places facing each other on the circumferential surface of the cylinder of the ίΪΠί. However, there is no limitation on the non-m health and the arbitrarily set, and it is only necessary to consider the size of the lens το 25GC and the holder unit 2, etc. In the case where the non-through hole 231 is formed, the convex portion 233 is formed in the shape of the It in the first specific example. ^ The mirror unit 2Q of the above configuration, t turns the fixing screw 29 into the present, and the clamping portion 232 is pushed by the turning action, so that the inner surface of the portion 240 is the thread of the internal thread portion 241 The tooth knife is deformed toward the same side as a. Thereby, the position of the lens unit 25A in the cylinder of the lens mounting portion 240 is fixed. At this time, since the fixing screw 29 is turned into the non-through hole 231, the front end of the fixing nail 20 does not directly contact the external thread portion 282 of the lens unit mounting portion 24, so that 'there is no The rigid shank of the fixing screw is in contact with the external thread portion 282 of the lens 25 〇 C to generate foreign matter. *In addition, since the mounting hole of the fixing screw 290 is a non-through hole 231, 'therefore, the holding frame unit 2〇〇c can be manufactured by molding processing, and the through hole processing and the burr removal are not required when the ^200C is manufactured. Since the cylinder _ thread portion is polished and then processed, the manufacturing cost of the slab to 200C can be easily reduced as compared with the case of the through hole structure. (2-3. Third Specific Example) Next, a third specific example will be described. Further, the case of the third specific example is the same as that of the second specific example or the second specific example. ° In the third specific example, the shape of the fixing screw that is transferred into the non-through hole is different from that of the second specific example.

However, for example, the thread portion is a threaded portion and has a pointed shape as shown in Fig. 10 (8). 'Specifically, a thread is formed near the front end of the part; the front end of the ^45' and up to the pointed sharp portion 292. The 尖, 彳 can also be used directly for using the fixing screw 29 nail 291 configured as described above When the non-through hole 231 is turned in, the fixing screw can function as a guide portion for thread insertion. In the case of the sharp portion 292, the sharp portion 292 can easily turn the fixing screw 291. Further, when the fixing screw 291 is turned into the non-through hole 2, the non-Bei Tong hole 231 is passed. The sharp portion 292 of the screw 291 reaches the top of the non-perpendicular fixed sharp portion 292 and is connected to the bottom surface, but At this time, when the clamping portion 232 is pressed toward the inside of the cylinder, the point at which the screw 291 can be contacted can be made. If the force of the pressing deformation can be concentrated, and the effect of the second function is not concentrated, the effect is exerted. The pressure of the force ^ increases. Because: the point is compared with the sharp part 292 The fixing screw 291 is second to two; if the 292 can be used, the clamping portion 232 can be easily deformed. Also, the case where the sharp portion 292 is sharp can be easily performed with a small force. Since the lock fastening a" is smaller than the tip and the handle portion 232 can be easily deformed, the locking force of the lens unit 250A with respect to the lens unit mounting portion 21b can be fixed by the nail 291. The position of the second embodiment of the above-described third embodiment of the present invention has been described in the first to third specific examples of the preferred embodiment of the fixed unit of the lens 19 201219874. The invention has been invented and limited to this. The screw unit is mounted on the mirror = 2 threaded portion: for example, when the overall structure of the camera device is formed, the same tubular shape and two mirrors and two lenses can be formed. The cylindrical shape is formed by another shape (the second example has been applied to the male screw portion and the male screw portion), but the present invention is not limited thereto, and the nominal diameter and the pitch of the first and second specific examples may be specified. The value of the change is appropriate. Of course, the setting screw and the fixing screw are turned. For example, as shown in FIG. 11( a ), the fixing screw 295 and the non-through hole 231 ′ to be transferred thereto may be provided to each other on at least one side (two sides in the illustrated example). The expansion protrusions 234 and 2% which are swollen toward each other are not in the case of the sharp portion 292 in the third embodiment, but also the end and the non-through of the fixing screw 295> The contact area of both the bottom surfaces of the holes 231 is suppressed, so that the interposed portion 232 can be easily deformed compared to the case where the expansion protrusions 234 and 296 are not provided. As for the shape of the bottom surface of the non-through holes 231, the shape of the bottom surface is Determined folder. Also, the degree of β 232 does not have to be the same. For example, as shown in Figs. 11 (9) to 11 (4), it is conceivable that the bottom surface shape of the non-through hole 231 is formed such that the intervening portion 232 partially has a weak portion 235 which is thin. In the case of such a configuration, since the weak portion 235 is present, the interposition portion 232 can be easily deformed. Further, unlike the case where the entire clamping portion 232 is thinned, it is rare that the clamping portion 232 20 201219874 is broken and the front end of the screw is inserted into the through hole 231, and can be turned in, f = Any one of the above-described fixing screws 290, 291, and 295 is provided in the non-constant portion 235 where the weak portion 235 is provided. It is not limited to the non-through hole of the loading body and the snail is inserted. The front end of the fixing screw is appropriately changed. More specifically, the design method: - the surface of the fixed screw can be considered as follows, as in the above various modifications ^ and two! A variety of different. The lens fixing unit allows it, and the device described is exactly the same. The photographs made by the brothers and the heads of the squatting 疋 ΐ ΐ ΐ ’ ’ ’ ’ ' lens fixed unit and camera device are not changed.
