New Type of Description: [Technical Fields of New Type] This creation is about a group of photographic phantoms that make a subject into an image pickup element by a photographic lens and generate an image data representing the subject at the image pickup element. . [Prior Art] | Most of the recent mobile phones have a built-in photography module (for example, refer to Patent Document 1). In this kind of photography module, in order to be able to take several actions, it is necessary to achieve miniaturization as much as possible. The above-mentioned Patent Document 1 introduces a photographic module that realizes miniaturization by using two members of the lens holder and the component holder as main constituent elements. In Patent Document 1, the photographic module is +-typed, that is, a thread is formed between the lens holder and the component holder, and at the time of focus adjustment, the lens holder moves the lens holder back and forth with respect to the component holder, thereby After the imaging element is located at the imaging position of the photographic lens in the lens holder, the lens holder and the component holder are fixed by adhesive bonding. However, if the above-described Patent Document i is provided with a screw thread on both the lens holder for focus adjustment and the component holder, the diameter of both the lens holder and the element holder will increase in any case. Therefore, the technique of arranging the above-described screw and the above-described component holder and constituting the photographic module by the lens holder and the substrate to which the imaging element is fixed has been proposed (for example, refer to Patent Document 2). 3 M370091 In the case of the patent document 2, the lens holder is moved back and forth with respect to the element holder in the optical axis direction instead of rotating the lens holder, and the imaging element is placed in the image while moving the substrate back and forth in the optical axis direction with respect to the lens holder. A technique in which the lens is imaged and fixed. The technique of Patent Document 2 is called a back focus adjustment method. If the back focus adjustment method is employed, it is not necessary to provide a thread on both the lens holder and the component holder, and the thickness of the photographic module can be reduced. Here, an example of the configuration of a photographing module to which the post-focus adjustment method is applied will be described. 10, Fig. 2, and Fig. 3 are views showing an example of a configuration of a photographing module to which a back focus adjustment method is applied. 1 is a perspective view of the photographing module 2 as seen obliquely from above, and FIG. 2 is an exploded view of FIG. 1 showing the center of the photographing module 2 of the cutaway view in FIG. 3 and observing the cut surface from the side. Side view. As shown in Fig. 2 and Fig. 3, the photographing module 2 shown in Fig. 1 includes a lens holder 20, a substrate 21 to which the imaging element 21A is fixed, and an imaging lens 22. The example in which the four lenses 220 to 223 and the spacer ring 224 are provided is shown in this example. The lens holder 20 shown in Fig. 1 holds the photographic lens 22 (Fig. 2) inside and has an object side aperture 20A and an imaging side aperture 200A ( image 3). When the imaging side aperture 200A of the lens holder 20 is fully assembled, the photographic lens 22 is first loaded into the lens holder 20 from the imaging side aperture 200A and fixed. Further, after the lens 22 is loaded, the substrate 21 to which the image pickup element 21 is fixed is bonded and fixed so that the image side aperture 200A of the lens holder 20 is plugged. M370091 Focus adjustment based on the back focus adjustment method is performed before the substrate 21 is fixed. In the example of FIG. 3, after the substrate 21 is sandwiched between the jigs 3, the smoothing device 3 is moved back and forth along the optical axis to perform the back focus adjustment. At this time, for example, an image indicating the inspection pattern for adjustment is generated in the imaging element. The signal is adjusted while the image signal is being monitored by 5, and the position of the substrate 21 is determined by the focus adjustment. Then, the substrate 21 whose position is determined is bonded and fixed to the lens holder 20°. However, in the structure of FIG. 3, When the substrate 21 is held by the jig 3, there is a problem that the substrate 21 is too thin and the substrate 21 is kept unstable by the jig. This unstable hold induces a deviation of the substrate or the like, which causes the adjustment accuracy of the focus to decrease. If the component cover can be attached to the substrate 21 of FIG. 1 to maintain the structure of the component cover, the substrate 21 can be stably held in the jig 3 and the adjustment precision of the focus adjustment can be improved. However, if so, the portion of the component cover is mounted. Will make the 15 photography module bigger. Patent Document 1. Japanese Laid-Open Patent Publication No. 2006-80961; Patent Document 2: International Publication No. WO2006/093377. [New content] In view of the above, the present invention aims to provide a photographing module capable of avoiding an increase in size even when a component cover for stably holding an image pickup element with a jig is attached, and a method of assembling the same. The photographic module of the present invention for achieving the above object comprises: 5 M370091 lens holder having an object side aperture and an imaging side aperture and holding the photographic lens in a state protruding from the imaging side aperture; a component cover having a housing photograph The lens is recessed from the projection side aperture and the imaging element is fixed to the bottom of the recess, and the component cover is fixed to the lens holder in a state in which the extension is received in the recess. According to the photographic module of the present invention described above, the component cover is provided on the substrate side and the component cover is fixed to the lens holder. In the photographic module of the present invention, the lens holder is changed from the structure in which the entire imaging lens is accommodated in the inside of the lens holder as described in Patent Document 1, and the lens holder is held in a state in which the imaging lens is extended from the imaging side aperture. A lens for a portion protruding from the lens holder is housed in a recess of the component cover. In this way, when the photographic module is assembled, the component cover that can be stably held is held by a jig or the like, and the focus adjustment can be performed after the component cover is moved back and forth. However, in the case where the concave portion of the element cover accommodates the projecting portion of the lens in place of the lens holder, the enlargement of the entire imaging module is avoided. Here, the above-described photographic module component cover is preferably adhesively fixed to the lens holder. When the photographic module is assembled, the component cover is held by a jig or the like, and the position of the component cover is determined by adjusting the position of the component cover while moving the image sensor of the component cover to the lens holder in the optical axis direction. Attach the component cover to the lens holder. Creation effect M370091 According to the present invention, a photographic module that can be prevented from being enlarged and a method of assembling the photographic module can be realized even if a component cover for stably holding the 7G component is mounted on the substrate side. 5 [Embodiment] Hereinafter, an embodiment of the present creation will be described with reference to the drawings. 4 and 5 are views showing the configuration of the photographing module 1 to which the present invention is applied. Fig. 4 is a perspective view showing the photographic module 从 as viewed obliquely from above, and Fig. 5 is a cross-sectional view showing the side of the photographic unit 图 of Fig. 4 and a side view of the 10 sides as viewed from the side. Fig. 4 shows a diagram corresponding to Fig. 4, and Fig. 5 shows a diagram corresponding to Fig. 3. The configuration of the photographing module 1 of the present embodiment will be described with reference to Figs. 4 and 5 . The substrate 21 of the conventional image pickup module described in Fig. 3 is too thin, and the substrate 21 cannot be stably held by the jig 3 in the holder 3. Here, in the configuration of Figs. 4 and 5, the component cover 110 is attached to the substrate 11, and the component cover 11 is held by the tripper 3. The lens holder 1 shown in Fig. 4 has an object side aperture 丨〇A and an imaging side aperture 100 A and holds the photographic lens 1 20 in a state of 20 extending from the imaging side aperture 1 〇〇a. Further, the element cover 110 has a concave portion 111 that accommodates an extending portion of the photographic lens 100 that protrudes from the imaging side aperture 100A, and an imaging element 112 is fixed to the bottom of the concave portion. That is, in the present embodiment, a configuration is adopted in which a part of the imaging side aperture is cut off with respect to the shape of the conventional lens holder 20 of Fig. 3, and the function of the portion where the M370091 is removed is distributed to the component cover 110, and the component cover is provided.丨1() holds the substrate 11. According to this configuration, when the photographic module 1 is assembled, the component cover 110 can be held by the jig 3 for back focus adjustment, and the holding strength by the detachment 3 can be improved. Therefore, the holding of the substrate 11 by the jig 3 is stabilized, and the stability of the image sensor 112 is increased with respect to the back and forth movement of the image pickup unit 112 together with the jig 3, and precise focus adjustment is performed. Further, the component cover 11 被 which is positioned by the focus adjustment is adhesively fixed to the imaging side aperture 100 Α side of the lens holder 10. Thereby, the focus bear is maintained. 10 [Brief Description of the Drawings] Fig. 1 is a perspective view showing a conventional photographic module. 2 is an exploded view of a conventional photographic module. 3 is a cross-sectional view of the photographing module of FIG. 1. 15 is a perspective view of a photographic module to which the present invention is applied.
