[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an oblique view showing an example of the configuration of a camera module 1 according to this embodiment, FIG. 2 is a side view showing an example of the configuration of one side of the camera module 1 shown in FIG. 1, and FIG. 3 is a top view showing an example of the configuration of the camera module 1 shown in FIG. 1 when viewed from above.

[0010] The camera module 1 externally comprises a lens unit 3, a front case 5 to which the lens unit 3 is attached, a rear case 7 that fits into the front case 5, and an attachment connector 9. The camera module 1 is used in different orientations depending on its intended use. The following embodiments and specific examples will be described with reference to the horizontal direction HR57, vertical direction VT57, Z direction, X direction, and Y direction shown in each drawing. In the following embodiments, a surface facing upward in the vertical direction VT57 may be referred to as the upper surface, and a surface facing downward in the vertical direction VT57 may be referred to as the lower surface. In the following embodiments and specific examples, the terms "form" and "provide" include integrally formed components and components that are formed separately and then bonded or welded. In the following embodiments and specific examples, the term "inside" refers to the closed space formed by fitting the front case 5 and the rear case 7 together. The term "outside" refers to the open space side, i.e., the side not included in the space.

[0011] When the lens unit 3 is disposed in the orientation shown in FIG. 2, it is located at the top of the camera module 1. The lens unit 3 is formed, for example, by connecting multiple cylinders with different radii, with the radius of the upper cylinder being larger than the radius of the lower cylinder. A screw thread is formed on the outer peripheral surface of the lower cylinder of the lens unit 3. To simplify the illustration, the screw thread is omitted. The lens unit 3 incorporates a lens 3A at the top. The convex lens surface 3B of the lens 3A is exposed on the top surface of the lens unit 3.

[0012] The front case 5 is formed, for example, as a hollow rectangular pillar. The front case 5 has rounded corners on the top surface thereof. A hole 5X into which the lower cylinder of the lens unit 3 described above can be inserted is formed on the top surface of the front case 5. A thread is formed on the inner peripheral surface of the hole to engage with the thread on the outer peripheral surface of the lower cylinder of the lens unit described above. To simplify the drawings, the thread is omitted. Therefore, the lens unit 3 described above is configured to be attachable to and detachable from the front case 5 by screwing its lower cylinder into the hole 5X of the front case 5.

[0013] The rear case 7 is formed, for example, as a hollow rectangular prism. The four corners of the bottom surface of the rear case 7 are rounded. The rear case 7 is fitted to the front case 5 described above. By fitting the rear case 7 to the front case 5, a space is formed between the rear case 7 and the front case 5. The periphery of the rear case 7 is the periphery of the end, including the end of the rear case 7. The periphery of the front case 5 is the periphery of the end, including the end of the front case 5.

[0014] The width W5 of the front case 5 in a direction perpendicular to the direction parallel to the optical axis 3C of the lens 3A is larger than the width W7 of the rear case 7. The difference between the width W5 of the front case 5 and the width W7 of the rear case 7 forms a third offset gap G57, which will be described in detail later.

[0015] An attachment connector 9 connectable to a connector 8 (described later) is provided on the bottom surface of the rear case 7 so as to extend in a direction parallel to the optical axis 3C of the lens 3A.

[0016] Fig. 4 is a partial cross-sectional view showing an example of the configuration of the camera module 1 shown in Fig. 1 etc. Fig. 5 is an enlarged view of the range R shown in Fig. 4. The example shown in Fig. 5 shows an enlarged view including the front case 5, the rear case 7, the adhesive 2, and the substrate 4. In the cross-sectional view shown in Fig. 4, hatching of the cross-sectional portion may be omitted for some of the configuration.

[0017] As shown in FIG. 4, when the periphery of the front case 5 is fitted onto the periphery of the rear case 7, an internal space is formed between the front case 5 and the rear case 7. The periphery of the front case 5 is fixed to the periphery of the rear case 7 by adhesive 2 applied between the periphery of the front case 5 and the periphery of the rear case 7. The adhesive 2 can be partially or completely hardened by ultraviolet light. If active alignment, which will be described later, is performed before hardening, the optical axis 3C of the lens 3A can be aligned with the image sensor 6, which will be described later.

[0018] A substrate 4 is housed inside the rear case 7. An image sensor 6 is provided on the substrate 4, for example, near the intersection with the optical axis 3C of the lens 3A of the lens unit 3 provided in the front case 5. A hole is provided on the bottom surface of the rear case 7 to which an attachment connector 9 is attached. The attachment connector 9 and a drive device 10 are provided on the bottom surface of the substrate 4.

[0019] The connector 8 is fitted to the mounting connector 9 to ensure electrical continuity between the mounting connector 9 and the substrate 4. The driving device 10 has an electronic circuit for driving the image sensor 6.

[0020] The periphery of the front case 5 and the periphery of the rear case 7 are bonded together with the substrate 4 by adhesive 2 as shown in the range R in FIG.

[0021] 5, a stepped portion 7B is formed by cutting out a rear case peripheral surface 7A, which is a surface parallel to the horizontal direction HR57 and facing the front case, of the periphery of the rear case 7. The substrate 4 is accommodated in the rear case 7 by being placed on the stepped portion 7B.

[0022] The step portion 7B is formed, for example, on the inside of the periphery of the rear case 7. At least a portion of the step portion 7B forms a step on the periphery of the rear case 7 in a direction perpendicular to the thickness direction of the rear case 7. The thickness direction of the rear case 7 is also referred to as the horizontal direction or horizontal direction HR57. The thickness direction is also referred to as the direction perpendicular to the optical axis direction of the lens 3A. The direction perpendicular to the thickness direction of the rear case 7 corresponds to the vertical direction VT57 in FIG. 5. The perpendicular direction is also referred to as the direction parallel to the optical axis 3C of the lens 3A.

[0023] The step portion 7B is formed by a bottom surface 7C, which is a surface parallel to the horizontal direction HR57, and a side peripheral surface 7G, which is a surface parallel to the vertical direction VT57. The bottom surface 7C of the step portion 7B supports the peripheral edge of the substrate 4. The bottom surface 7C supports the bottom surface of the substrate 4, which is a surface of the peripheral edge of the substrate 4 that is parallel to the horizontal direction HR57 and is located downward in the vertical direction VT57. The side peripheral surface 7G of the step portion 7B supports the peripheral edge of the substrate 4. The side peripheral surface 7G of the step portion 7B supports the side surface of the substrate 4, which is a surface of the peripheral edge of the substrate 4 that is parallel to the vertical direction VT57. The substrate 4 is placed on the bottom surface 7C of the step portion 7B.

[0024] The adhesive 2 integrally bonds together a front case peripheral surface 5A formed on the peripheral edge of the front case 5, the peripheral edge of the substrate 4 placed on the bottom surface of the stepped portion 7B of the rear case 7, and a rear case peripheral surface 7A formed on the peripheral edge of the rear case 7. The adhesive 2 also functions as a sealant that seals the space formed by the front case 5 and the rear case 7.

[0025] The front case peripheral surface 5A is a surface located on the periphery of the front case 5 and is a surface parallel to the horizontal direction HR57. The periphery of the substrate 4 is formed by a side surface 5E of the substrate 4, which is a surface parallel to the vertical direction VT57, and an upper surface 5D, which is a part of the periphery of the substrate 4 and is a surface parallel to the horizontal direction HR57. The rear case peripheral surface 7A is a surface located on the periphery of the rear case 7 and is a surface parallel to the horizontal direction HR57. When the front case 5 is fitted to the rear case 7, the front case peripheral surface 5A faces the rear case peripheral surface 7A.

[0026] In this embodiment, a height H7 from a bottom surface 7C of the step portion 7B in the rear case 7 to a rear case peripheral surface 7A located on the peripheral edge of the rear case 7 is lower than a height H4 from the bottom surface 7C of the step portion 7B to the substrate 4. A first offset portion 7F is formed on the peripheral edge of the rear case 7 due to the difference between the height H7 of the step portion 7B and the height H4 to the upper surface of the substrate 4.

[0027] In this embodiment, when the rear case 7 is fitted to the front case 5, a protrusion 5Z that protrudes from the front case 5 toward the rear case 7 is formed on at least a part of the periphery of the front case 5. As an example, the protrusion 5Z is formed around the entire periphery of the front case 5. The protrusion 5Z is not limited to the example provided, and for example, the protrusion 5Z may be formed by cutting out the entire periphery or a part of the outer periphery of the front case 5, or the protrusion 5Z may be formed by cutting out the entire periphery or a part of the inner periphery of the front case 5, or a combination of these may be used.

[0028] The protrusion 5Z protrudes in the vertical direction VT57 beyond the upper surface 5B of the adhesive 2. When the rear case 7 is fitted to the front case 5, the protrusion 5Z protrudes beyond the upper surface 5B of the adhesive 2 toward the peripheral surface 7A of the rear case. The height H5 of the protrusion 5Z is the distance from the upper surface 5B of the adhesive 2 to the peripheral surface 5A of the front case in the vertical direction VT57. A second offset portion 5C is formed on the peripheral edge of the front case 5 by the height H5.

[0029] The width W5 of the front case 5 in the horizontal direction HR57 is larger than the width W7 of the rear case 7 in the horizontal direction HR57. As shown in FIG. 1, the width W5 is the distance from the left side surface to the right side surface on the outer periphery of the front case 5 in the horizontal direction HR57. As shown in FIG. 1, the width W7 is the distance from the left side surface to the right side surface on the outer periphery of the rear case 7 in the horizontal direction HR57. The left side surface and the right side surface can be interchangeably referred to as one side surface and the other side surface. As shown in FIG. 5, the difference between the left side surface 5L of the front case 5 and the left side surface 7L of the rear case 7 in the horizontal direction HR57 corresponds to a third offset gap G57. This difference is also referred to as a predetermined width. In this embodiment, a third offset portion 7D is formed, which is configured by the third offset gap G57 of the predetermined width.

[0030] The adhesive 2 contacts a front case peripheral surface 5A formed on the periphery of the front case 5, a side surface 5E which is part of the periphery of the substrate 4, a top surface 5D which is part of the periphery of the substrate 4, and a rear case peripheral surface 7A which is formed on the periphery of the rear case 7.

[0031] The second offset portion 5C on the periphery of the front case 5 includes the front case peripheral surface 5A described above and an inner side surface 5C1 of the periphery of the front case 5 that is the inside of the front case 5, and the front case peripheral surface 5A and the inner side surface 5C1 are in contact with the adhesive 2. The inner side surface 5C1 is the inner side of the periphery of the front case 5 and is a surface parallel to the vertical direction VT57. The adhesive 2 is in contact with the front case peripheral surface 5A formed on the periphery of the front case 5, the side surface 5E that is part of the periphery of the substrate 4, the top surface 5D that is part of the periphery of the substrate 4, the rear case peripheral surface 7A formed on the periphery of the rear case 7, and the inner side surface 5C1 that constitutes the inner periphery of the periphery of the front case 5.

[0032] The camera module 1 according to this embodiment has the above configuration. An example of the procedure for assembling the camera module 1 according to this embodiment will be disclosed. First, the lens unit 3 is screwed into the front case 5 along the threads shown in the attached drawings. The substrate 4 is attached to the stepped portion 7B of the rear case 7. An adhesive 2 is applied to the rear case peripheral surface 7A of the peripheral portion of the rear case 7, including the peripheral edge of the substrate 4. As shown in FIG. 6 , the peripheral edge of the front case 5 is fitted to the peripheral edge of the rear case 7, and the front case 5 is attached to the rear case 7. The image sensor 6 is mounted near the position where the optical axis 3C of the lens 3A of the lens unit 3 provided in the front case 5 intersects with the substrate 4.

[0033] Next, active alignment is performed. As shown in FIG. 6 , the front case 5 is swung relative to the rear case 7 in the Z direction, which is a direction parallel to the optical axis 3C, and in the X and Y directions perpendicular to the Z direction, and is also rotated in the X and Y directions. This adjusts the orientation of the front case 5 relative to the rear case 7 in the Z direction, which is parallel to the optical axis 3C. The optical axis 3C of the lens 3A of the lens unit 3 is adjusted so that it passes through, for example, the center or near the center of the image sensor 6 provided on the substrate 4. In other words, the position of the front case 5 relative to the rear case 7 is adjusted by swinging the front case 5 or the rear case 7 in the X and Y directions.

[0034] When the adhesive 2 is partially or completely hardened by ultraviolet light emitted from the ultraviolet irradiation device 100, the orientation of the optical axis 3C of the lens 3A of the lens unit 3 is fixed relative to the image sensor 6 provided on the substrate 4 of the rear case 7.

[0035] Fig. 7 is a partial cross-sectional view showing an example of how the above-mentioned active alignment is performed. Fig. 8 is an enlarged view of the range R of the camera module 1 when the execution of the active alignment shown in Fig. 7 is completed.

[0036] Even when the rear case 7 is swung relative to the front case 5 as shown by the dashed line due to active alignment, the rear case 7 does not protrude beyond the width W5 of the front case 5. That is, due to the presence of the third offset portion 7D defined by the third offset gap G57 of a predetermined width, the rear case 7 in the horizontal direction HR57 is contained within the width W5 of the front case 5, as shown in FIG.

[0037] 9 to 11 are diagrams showing specific examples of the above-mentioned step portion 7B. The configuration common to each specific example is disclosed below. The bottom surface 7C of the step portion 7B is the periphery of the substrate 4 and supports the bottom surface of the substrate 4. The bottom surface 7C contacts, for example, the lower surface of the substrate 4 where the image sensor 6 is not provided. The side peripheral surface 7G of the step portion 7B is the periphery of the substrate 4 and supports at least a part of the side surface of the substrate 4. The end of the bottom surface 7C contacts the side peripheral surface 7G. As a result, the substrate 4 is supported by both the bottom surface 7C and the side peripheral surface 7G. The above is the configuration common to each specific example.

[0038] As specific examples of the step portion 7B, a first step portion 7B1, a second step portion 7B2, and a third step portion 7B3 are disclosed below. Note that in this embodiment and specific examples, when the term "step portion 7B" is used, the step portion 7B includes the first step portion 7B1, the second step portion 7B2, and the third step portion 7B3. In this embodiment and specific examples, when the term "bottom surface 7C" is used, the bottom surface 7C includes the bottom surface 7C1, the bottom surface 7C2, and the bottom surface 7C3 described below.

[0039] The first step portion 7B1 shown in FIG. 9 is formed as a rectangle along the inside of the rear case peripheral surface 7A, spanning the entire periphery. The first step portion 7B1 includes a bottom surface 7C1 and side surfaces 7G. The bottom surface 7C1 of the rectangle is a plane that is parallel to the horizontal direction HR57 and is positioned upward in the vertical direction VT57. The first step portion 7B1 supports the bottom surface and side surfaces of the substrate 4 along the entire periphery, along the inside of the rear case peripheral surface 7A.

[0040] The second step portion 7B2 shown in FIG. 10 is formed in a columnar shape extending in the vertical direction VT57 along the inner side of the rear case peripheral surface 7A. The second step portion 7B2 includes a bottom surface 7C2 and a side peripheral surface 7G. The bottom surface 7C2 of the columnar shape is a plane parallel to the horizontal direction HR57 and positioned upward in the vertical direction VT57. The shape of the bottom surface 7C2 is not limited to a rectangle and may be, for example, a circle. The second step portion 7B2 partially supports the bottom surface of the substrate 4 along the inner side of the rear case peripheral surface 7A. The side peripheral surface 7G has a configuration similar to that of the side peripheral surface 7G shown in FIG. 9. The position at which the second step portion 7B2 is provided is not limited, and the second step portion 7B2 may be provided at a corner of the rear case peripheral surface 7A. This configuration reduces the number of components constituting the step portion 7B2 compared to the configuration shown in FIG. 9. This configuration also reduces the overall weight compared to the configuration shown in FIG. 9.

[0041] The third step portion 7B3 shown in FIG. 11 is formed inside the rear case peripheral surface 7A along a corner of the rear case 7 and has an L-shape extending in the vertical direction VT57. The third step portion 7B3 is partially formed around the corner of the rear case 7. The third step portion 7B3 includes a bottom surface 7C3 and a side peripheral surface 7G. The bottom surface 7C3 of the columnar shape is a plane parallel to the horizontal direction HR57 and positioned upward in the vertical direction VT57. The side peripheral surface 7G has a configuration similar to that of the side peripheral surface 7G shown in FIG. 9. The third step portion 7B3 partially supports the bottom surface of the substrate 4 along the inside of the rear case peripheral surface 7A. This configuration allows for a reduction in the number of components constituting the step portion 7B3 compared to the configuration shown in FIG. 9, thereby achieving a lighter overall weight compared to the configuration shown in FIG. Furthermore, the third step portion 7B3 supports the corners of the substrate 4 along the inner side of the rear case peripheral surface 7A. This configuration makes the substrate 4 more stable than the configuration shown in FIG.

[0042] The camera module 1 of this embodiment is a camera module 1 comprising a front case 5 to which a lens unit 3 is attached, and a rear case 7 that fits into the front case 5, and is provided with a step portion 7B that is a step formed inside the periphery of the rear case 7 and formed in a direction perpendicular to the thickness direction of the rear case 7, a substrate 4 placed on a bottom surface 7C of the step portion 7B, and an adhesive 2 that bonds together the front case peripheral surface 5A formed on the periphery of the front case 5, the periphery of the substrate 4 placed on the bottom surface of the step portion 7B in the rear case 7, and the rear case peripheral surface 7A formed on the periphery of the rear case 7, and is configured so that the height from the bottom surface 7C of the step portion 7B to the rear case peripheral surface 7A is lower than the height from the bottom surface of the step portion 7B to the top surface 5D of the substrate 4.

[0043] This configuration can improve the resistance of the periphery of the front case 5 and the periphery of the rear case 7 to forces applied in the horizontal direction.

[0044] The camera module 1 according to this embodiment includes a protrusion 5Z that protrudes toward the peripheral surface 7A of the rear case from the upper surface 2B of the adhesive 2. This configuration can further improve the resistance of the peripheral edges of the front case 5 and the peripheral edges of the rear case 7 to forces applied in the horizontal direction.

[0045] In the camera module 1 according to this embodiment, a width W5, which is the distance from one side surface to the other side surface in the thickness direction on the outer periphery of the front case 5, is configured to be larger than a width W7, which is the distance from one side surface to the other side surface on the outer periphery of the rear case 7. With this configuration, even if active alignment is performed to focus the lens 3A of the lens unit 3, the front case 5 and the rear case 7 can be finally fixed together with the rear case 7 located more inward than the front case 5.

[0046] In camera module 1 according to this embodiment, the periphery of substrate 4 is formed by the side surfaces of substrate 4, which are surfaces of the periphery of substrate 4 that are parallel to the thickness direction and perpendicular to the thickness direction, and the top surface of substrate 4, which is a surface horizontal to the thickness direction, and adhesive 2 contacts front case peripheral surface 5A formed on the periphery of front case 5, side surfaces 5E that are part of the periphery of substrate 4, top surface 5D that is part of the periphery of substrate 4, and rear case peripheral surface 7A formed on the periphery of rear case 7. With this configuration, adhesive 2 simultaneously bonds front case 5, rear case 7, and substrate 4 as a single unit, simplifying the process. Furthermore, the manufacturing cost of camera module 1 can be reduced.

[0047] In the camera module 1 according to this embodiment, the second offset portion 5C is formed by a front case peripheral surface 5A, which is a surface located on the periphery of the front case 5 and is parallel to the thickness direction, and an inner surface 5C1 of the periphery of the front case 5, which is on the inside of the front case 5, and the front case peripheral surface 5A and the inner surface 5C1 are in contact with the adhesive 2. This configuration can further improve the resistance of the periphery of the rear case 7 and the front case 5 to forces applied from the horizontal direction.

[0048] The present invention is not limited to the above-described embodiments, and includes various modifications and equivalent configurations within the spirit and scope of the appended claims. For example, the above-described embodiments have been described in detail to clearly explain the present invention, and the present invention is not necessarily limited to those including all of the described configurations. Furthermore, the elements described in parallel in the present embodiment may be configured such that at least one of the elements is connected in series to the other elements.
