Description

[Technical Field]

[0001] The present invention relates to a fixing structure, an assembling method and an electronic device. [Background Art]

[0002] In recent years, techniques for fixing substrates have been known. For example, Patent Document 1 discloses a technique for fixing a substrate to a fixing plate by fitting a protrusion provided on the fixing plate into a hole provided in the substrate. [Prior Art Literature] [Patent Literature]

[0003] [Patent Document 1] Japanese Unexamined Patent Application Publication No. 2006-135042 [Summary of the Invention] [Problem to be Solved by the Invention]

[0004] However, the technique that can only fix a substrate provided with holes cannot fix a substrate that is not provided with holes. That is, in a technique for fixing a substrate in which holes can be formed, restrictions may be imposed on fixable substrates.

[0005] Accordingly, it is desired to provide a technique capable of relaxing restrictions imposed on fixable substrates. [Means for Solving the Problem]

[0006] To solve the above problems, according to one aspect of the present invention, a fixing structure for fixing a substrate is provided, comprising: a first member having a proximity surface in close proximity to the substrate; a rotation restricting portion that restricts the substrate from rotating in a predetermined direction by contacting the substrate when the substrate is in close proximity to the proximity surface; and a movement restricting portion located at a position that restricts the substrate from moving away from the proximity surface; and a second member provided at a position that restricts the substrate from rotating in a direction opposite to the predetermined direction.

[0007] The upper surface of the second member may be located higher than the lower surface of the substrate when the substrate is in close proximity to the adjacent surface.

[0008] The fixing structure includes a third member located at a position that restricts the substrate from moving away from the adjacent surface, and the third member may be fixed to the upper surface of the second member.

[0009] The second member may have an insertion hole on its upper surface into which a fastener for fixing the third member is inserted.

[0010] The third component may be configured to accommodate a clamp for bundling the wiring connected to the substrate.

[0011] The third member may be made up of a metal material and may be electrically connected to the component of the substrate by contact with the component.

[0012] The rotation restricting portion comes into contact with the substrate when the substrate approaches the proximity surface and is rotated in the predetermined direction, and the second member may be positioned to restrict the substrate from rotating in the opposite direction after the substrate has come into contact with the rotation restricting portion.

[0013] The predetermined direction may be a direction included in a plane parallel to the upper surface of the substrate.

[0014] The fixing structure may comprise a plurality of the first members.

[0015] Furthermore, in order to solve the above problems, according to another aspect of the present invention, an assembly method is provided which includes bringing a substrate close to a proximity surface of a first member, rotating the substrate in a predetermined direction while bringing it close to the proximity surface so that the substrate comes into contact with a rotation restricting portion of the first member, and positioning a second member at a position that restricts the substrate from rotating in the opposite direction to the predetermined direction.

[0016] Furthermore, in order to solve the above problems, according to another aspect of the present invention, there is an electronic device having a first member comprising a proximity surface in close proximity to a substrate, a rotation restricting portion that restricts the substrate from rotating in a predetermined direction by contacting the substrate when the substrate is in close proximity to the proximity surface, and a movement restricting portion located at a position that restricts the substrate from moving away from the proximity surface, and a second member provided at a position that restricts the substrate from rotating in a direction opposite to the predetermined direction. [Effects of the Invention]

[0017] As described above, the present invention provides a technology that can alleviate the constraints imposed on a fixable substrate. [Brief explanation of the drawing]

[0019] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the present specification and the drawings, constituent elements having substantially the same functional configuration are denoted by the same reference numerals, and redundant description is omitted.

[0020] <<0. Overview>> First, an outline of an embodiment of the present invention will be described.

[0021] In recent years, techniques for fixing a substrate have been known. For example, a technique is known in which a round hole is provided in a substrate, a male screw is inserted into the round hole, and the substrate is fixed to a female screw provided on a sheet metal. According to this technique, the substrate is fixed so as to be sandwiched between the male screw and the sheet metal. However, this technique can only fix a substrate provided with a round hole.

[0022] Further, as described above, a technique is known in which a substrate is fixed to a fixing plate by fitting a protrusion provided on the fixing plate into a hole provided in the substrate. However, a technique that can only fix a substrate provided with a hole cannot fix a substrate that is not provided with a hole.

[0023] In other words, in technologies like these, which can only fix substrates with holes, there may be limitations on the types of substrates that can be fixed.

[0024] Furthermore, a guide rail structure can be used as a technique for fixing the substrate. However, problems may arise even when using a guide rail structure. Referring to Figures 1 and 2, the structure of the substrate 10 according to the first embodiment of the present invention will be described, and the problems that arise when a guide rail structure is used as the fixing structure will be explained.

[0025] Figure 1 is a perspective view showing the external appearance of a substrate 10 according to a first embodiment of the present invention. As shown in Figure 1, the substrate 10 according to the first embodiment of the present invention comprises a component placement plate 110 and components 120.

[0026] The component placement plate 110 is a plate-shaped member on which the components 120 are placed. In the following description, the surface on which the components 120 are placed among the multiple surfaces of the component placement plate 110 is also referred to as the "upper surface of the component placement plate 110" or the "upper surface of the substrate 10".

[0027] On the other hand, the back surface of the surface on which the components 120 are placed, among the multiple surfaces of the component placement plate 110, is also referred to as the "bottom surface of the component placement plate 110" or the "bottom surface of the substrate 10." This back surface may be the surface of the component placement plate 110 opposite to the surface on which the components 120 are placed. Furthermore, this back surface may be a surface parallel to the surface on which the components 120 are placed, among the multiple surfaces of the component placement plate 110.

[0028] Furthermore, in the following explanation, the direction perpendicular to the upper surface of the component placement plate 110 and away from the upper surface of the component placement plate 110 will also be referred to as "up." Similarly, the direction perpendicular to the lower surface of the component placement plate 110 and away from the lower surface of the component placement plate 110 will also be referred to as "down."

[0029] Component 120 is placed on the upper surface of the component placement plate 110. Various types of components can be assumed for component 120. Component 120 may be an electronic component. In the following explanation, components 120A to 120E will appear as specific examples of component 120. The term "component 120" is mainly used when explaining the common content of components 120A to 120E without distinguishing between them as specific examples.

[0030] Figure 2 is a top view of a substrate 10 according to the first embodiment of the present invention. Referring to Figure 2, as an example, components 120A to 120C are arranged on the peripheral edge of the component placement plate 110. Note that Figure 2 only shows an example of a substrate 10 in which problems are likely to occur when a guide rail structure is used as the fixing structure, so in the first embodiment of the present invention, components 120A to 120C must not necessarily be arranged in the peripheral regions of three of the four sides that constitute the component placement plate 110.

[0031] When a guide rail structure is used as the fixing structure, it is necessary to slide the substrate 10 along the grooves of the two guide rails located on either side of the two parallel sides of the component placement plate 110. However, when the substrate 10 slides along the two guide rail grooves, there is a possibility that at least one of the two guide rails may come into contact with at least one of the components 120A to 120C.

[0032] Therefore, when a guide rail structure is used as the fixing structure, it may not be possible to fix the substrate 10 if components are placed on the peripheral edge of the component placement plate 110. In other words, even when a guide rail structure is used as the fixing structure, there may still be limitations on the substrate 10 that can be fixed.

[0033] Therefore, this specification will mainly describe techniques that can alleviate the constraints imposed on the fixable substrate 10. In the examples shown in Figures 1 and 2, the top and bottom surfaces of the substrate 10 are rectangular. However, the top and bottom surfaces of the substrate 10 may have shapes other than rectangular. For example, the top and bottom surfaces of the substrate 10 may be polygonal, circular, or elliptical.

[0034] The above describes the general outline of embodiments of the present invention. Hereinafter, each embodiment of the present invention will be described sequentially.

[0035] <<1. First Embodiment>> First, a first embodiment of the present invention will be described. The fixing structure according to the first embodiment of the present invention is provided, for example, in an electronic device. The fixing structure has the function of fixing the substrate 10 described above.

[0036] (1.1. Fixed structure) Next, a fixing structure according to the first embodiment of the present invention will be described.

[0037] Figure 3 is a perspective view showing the appearance of a fixing plate in a fixing structure according to the first embodiment of the present invention. As shown in Figure 3, the fixing plate 20 in the fixing structure according to the first embodiment of the present invention comprises a member arrangement plate 210, a plurality of fixing members 220, and a plurality of holes 230.

[0038] The component placement plate 210 is a plate-shaped component on which multiple fixing members 220 are arranged. The component placement plate 210 has multiple holes 230. In the following description, the surface on which the multiple fixing members 220 are arranged among the multiple surfaces of the component placement plate 210 is also referred to as the "upper surface of the component placement plate 210" or the "upper surface of the fixing plate 20".

[0039] On the other hand, the back surface of the surface on which the multiple fixing members 220 are arranged among the multiple surfaces of the component arrangement plate 210 is also called the "bottom surface of the component arrangement plate 210" or the "bottom surface of the fixing plate 20". This back surface may be the surface of the component arrangement plate 210 opposite to the surface on which the multiple fixing members 220 are arranged. Furthermore, this back surface may be a surface parallel to the surface on which the multiple fixing members 220 are arranged among the multiple surfaces of the component arrangement plate 210.

[0040] On the other hand, the back surface of the surface on which the components 120 are placed, among the multiple surfaces of the component placement plate 110, is also referred to as the "bottom surface of the component placement plate 110" or the "bottom surface of the substrate 10." This back surface may be the surface of the component placement plate 110 opposite to the surface on which the components 120 are placed. Furthermore, this back surface may be a surface parallel to the surface on which the components 120 are placed, among the multiple surfaces of the component placement plate 110.

[0041] Each of the multiple fixing members 220 may correspond to the first member. Each of the multiple fixing members 220 has the function of fixing the substrate 10. Each of the multiple fixing members 220 includes a proximity surface 222, a rotation restricting part 224, and a movement restricting part 226.

[0042] In the following explanation, the term "fixing member 220" is mainly used to describe the common features of fixing members 220A to 220D without distinguishing between them as specific examples. In the example shown in Figure 3, there are four fixing members 220. However, the number of fixing members 220 may be two, three, or five or more. In order to firmly fix the substrate 10, it is desirable to have multiple fixing members 220, but the number of fixing members 220 may be just one.

[0043] The fixing member 220A includes a proximity surface 222A, a rotation restricting part 224A, and a movement restricting part 226A. The fixing member 220B also includes a proximity surface 222B, a rotation restricting part 224B, and a movement restricting part 226B. The fixing member 220C includes a proximity surface 222C, a rotation restricting part 224C, and a movement restricting part 226C. The fixing member 220D includes a proximity surface 222D, a rotation restricting part 224D, and a movement restricting part 226D.

[0044] The term "proximity surface 222" is primarily used to describe the common features of proximity surfaces 222A to 222D without distinguishing between specific examples of proximity surfaces 222A to 222D. Similarly, the term "rotation restricting section 224" is primarily used to describe the common features of rotation restricting sections 224A to 224D without distinguishing between specific examples of rotation restricting sections 224A to 224D. The term "movement restricting section 226" is primarily used to describe the common features of movement restricting sections 226A to 226D without distinguishing between specific examples of movement restricting sections 226A to 226D.

[0045] A post 240, which will be described later, is inserted into each of the multiple holes 230.

[0046] In the following explanation, the term "hole 230" is primarily used to describe the common features of holes 230A to 230D without distinguishing between them as specific examples. In the example shown in Figure 3, there are four holes 230. However, the number of holes 230 may be two, three, or five or more. While it is desirable to have multiple holes 230 to firmly secure the substrate 10, it may also be possible to have only one hole 230.

[0047] There are at least as many holes 230 as there are posts 240 inserted into the holes 230. As shown in Figure 3, the number of holes 230 may be the same as the number of fixing members 220, but the number of holes 230 may not be the same as the number of fixing members 220.

[0048] Figure 4 is a top view of a fixing plate 20 having a fixing structure according to the first embodiment of the present invention. As shown in Figure 4, each of the holes 230A to 230D may be located at the end of the member placement plate 210. More specifically, the holes 230A to 230D may be located at the four corner ends of the member placement plate 210.

[0049] Furthermore, the fixing members 220A and 220C may be located in positions that are point-symmetrical to each other with respect to the center of the upper surface of the member placement plate 210. That is, if the position and orientation of one of the fixing members 220A and 220C is rotated 180 degrees in the rotational direction R1 (Figure 5) with respect to the center of the upper surface of the member placement plate 210, the position and orientation after rotation may coincide with the position and orientation of the other. In other words, the fixing members 220A and 220C may be located diagonally opposite each other with respect to the center of the upper surface of the member placement plate 210. Note that if the position and orientation of one of the fixing members 220A and 220C is rotated 180 degrees in the rotational direction R1 (Figure 5) with respect to the center of the upper surface of the member placement plate 210, the position and orientation after rotation do not necessarily coincide with the position and orientation of the other.

[0050] Similarly, the fixing members 220B and 220D may be located in positions that are point-symmetrical to each other with respect to the center of the upper surface of the member placement plate 210. That is, if the position and orientation of one of the fixing members 220B and 220D is rotated 180 degrees with respect to the center of the upper surface of the member placement plate 210, it may coincide with the position and orientation of the other. In other words, the fixing members 220B and 220D may be located diagonally opposite each other with respect to the center of the upper surface of the member placement plate 210. Note that if the position and orientation of one of the fixing members 220B and 220D is rotated 180 degrees with respect to the center of the upper surface of the member placement plate 210, it is not necessary for it to coincide with the position and orientation of the other.

[0051] The proximity surface 222 is in close proximity to the substrate 10. The proximity surface 222 may or may not be in contact with the substrate 10. For example, the substrate 10 may be brought close to the proximity surface 222 by an assembly worker or machine.

[0052] Figure 5 is a top view showing the state in which the substrate 10 is in close proximity to the proximity surface 222 (Figure 3) of the fixing member 220. In the example shown in Figure 5, the substrate 10 has not yet been rotated in the rotational direction R1, so the orientation of the substrate 10 is inclined with respect to the orientation of the member placement plate 210.

[0053] As described above, since fixing members 220A and 220C are located diagonally opposite each other, the distance between fixing members 220A and 220C is wide. Similarly, since fixing members 220B and 220D are located diagonally opposite each other, the distance between fixing members 220B and 220D is wide. Therefore, if an assembly worker or machine tilts the orientation of the substrate 10 relative to the orientation of the component placement plate 210 and brings the substrate 10 close to the component placement plate 210, the substrate 10 will come into close proximity with the proximity surface 222 (Figure 3).

[0054] The rotation restricting unit 224 comes into contact with the substrate 10 when the substrate 10 approaches the proximity surface 222 and is then rotated in the rotational direction R1. For example, the rotation restricting unit 224 comes into contact with the substrate 10 when it is rotated in the rotational direction R1 by an assembly worker or machine. The rotation restricting unit 224 restricts the substrate 10 from rotating further in the rotational direction R1 once it is in contact with the rotation restricting unit 224.

[0055] The rotation direction R1 is a predetermined direction and may be a direction included in a plane parallel to the upper surface of the substrate 10. By rotating the substrate 10 in such a rotation direction R1, the substrate 10 can rotate while approaching the proximity surface 222. In the example shown in Figure 5, the rotation direction R1 is counterclockwise (left rotation) when viewed from above, but the rotation direction R1 may also be clockwise (right rotation) when viewed from above.

[0056] As described above, since the fixing members 220A and 220C are located diagonally opposite each other, even if a force is applied to rotate the substrate 10 in the rotational direction R1, a repulsive force acts between the fixing members 220A and 220C to prevent rotation. Similarly, since the fixing members 220B and 220D are located diagonally opposite each other, even if a force is applied to rotate the substrate 10 in the rotational direction R1, a repulsive force acts between the fixing members 220B and 220D to prevent rotation.

[0057] Figure 6 is a top view showing the state in which the substrate 10 is in contact with the rotation restricting portion 224 (Figure 5) of the fixing member 220. The fixing structure 30 comprises a fixing plate 20 and a plurality of posts 240. In the example shown in Figure 6, since the substrate 10 has been rotated in the rotation direction R1, the orientation of the substrate 10 is not tilted with respect to the orientation of the member placement plate 210.

[0058] The movement restricting unit 226 is positioned to restrict the substrate 10 from moving away from the proximity surface 222 (Figure 3). The movement restricting unit 226 restricts the substrate 10 from moving away from the proximity surface 222.

[0059] Each of the multiple posts 240 may correspond to a second component. Each of the multiple posts 240 is positioned to restrict the substrate 10 from rotating in the reverse direction R2, which is the opposite direction to the rotation direction R1. The posts 240 restrict the substrate 10 from rotating in the reverse direction R2 from a state in contact with the rotation restricting part 224.

[0060] More specifically, the upper surface of the post 240 is located higher than the lower surface of the substrate 10 when the substrate 10 is in close proximity to the proximity surface 222. As a result, even if a force acts to rotate the substrate 10 in the opposite direction R2, the post 240 acts as a repulsive force on the substrate 10 that prevents rotation in the opposite direction R2.

[0061] In the following explanation, the term "post 240" is primarily used to describe the common features of posts 240A to 240D without distinguishing between them as specific examples. In the example shown in Figure 6, there are four posts 240. However, there may be two, three, or five or more posts 240. While it is desirable to have multiple posts 240 to firmly secure the substrate 10, there may be only one post 240.

[0062] The posts 240 are positioned to restrict the rotation of the substrate 10 in the reverse direction R2 by an assembler or machine after the substrate 10 has come into contact with the rotation restricting section 224. For example, the posts 240 may be positioned by inserting post 240A into hole 230A (Figure 4), post 240B into hole 230B (Figure 4), post 240C into hole 230C (Figure 4), and post 240D into hole 230D (Figure 4). This completes the assembly process (i.e., the process of fixing the substrate 10 to the fixing plate 20).

[0063] In the example shown in Figure 6, the post 240 is hexagonal when viewed from above. However, the post 240 may have a shape other than hexagonal when viewed from above (for example, a circular shape). The post 240 has an insertion hole 242 into which a fastener 250 is inserted on its upper surface. The fastener 250 and the insertion hole 242 will be described in detail in a second embodiment of the present invention.

[0064] In the following explanation, the term "fixing device 250" is primarily used to describe the common features of fixing devices 250A to 250D without distinguishing between them as specific examples. Similarly, the term "insertion hole 242" is primarily used to describe the common features of insertion holes 242A to 242D without distinguishing between them as specific examples.

[0065] Specifically, the fixing device 250A has an insertion hole 242A, the fixing device 250B has an insertion hole 242B, the fixing device 250C has an insertion hole 242C, and the fixing device 250D has an insertion hole 242D.

[0066] Figure 7 shows the completed assembly. Referring to Figure 7, the assembly is complete and the substrate 10 is fixed in place by the fixing structure 30.

[0067] The fixed structure 30 according to the first embodiment of the present invention has been described above.

[0068] (1.2. Assembly Instructions) Next, we will summarize the assembly method (i.e., the method of fixing the circuit board 10 to the fixing plate 20) with reference to Figures 1 to 7.

[0069] First, the assembly worker or machine brings the substrate 10 close to the proximity surface 222 of the fixing member 220. Next, the assembly worker or machine rotates the substrate 10 in the rotational direction R1 while bringing it close to the proximity surface 222, thereby bringing the substrate 10 into contact with the rotation restricting part 224 of the fixing member 220. Subsequently, the assembly worker or machine positions the post 240 in a position that restricts the substrate 10 from rotating in the opposite direction R2, which is opposite to the rotational direction R1. In this way, the work of fixing the substrate 10 to the fixing plate 20 is completed.

[0070] The assembly method according to the first embodiment of the present invention has been described above.

[0071] (1.3. Effects) As described above, according to the first embodiment of the present invention, the substrate 10 is fixed to the fixing plate 20 by rotating the substrate 10 until it contacts the rotation restricting portion 224 provided on the fixing member 220. With this configuration, it is possible to relax the constraints imposed on the substrate 10 that can be fixed, compared to cases where only substrates with holes can be fixed, or when a guide rail structure is used.

[0072] Furthermore, according to the embodiment of the present invention, the post 240 restricts the rotation of the substrate 10 in the opposite direction R2, which is the opposite direction to the rotation direction R1. Also, the position of the substrate 10 is determined by the position where the post 240 is provided. Therefore, when it is required to improve the accuracy of the fixed position of the substrate 10, the post 240 plays an important role in improving the accuracy of the fixed position of the substrate 10.

[0073] The first embodiment of the present invention has been described above.

[0074] <<2. Second Embodiment>> Next, a second embodiment of the present invention will be described. In the following, detailed descriptions of the configurations of the second embodiment of the present invention that are common with the configuration of the first embodiment of the present invention will be omitted, and the configurations that differ from the configuration of the first embodiment of the present invention will be mainly described.

[0075] (2.1. Fixed structure) First, a fixing structure according to a second embodiment of the present invention will be described.

[0076] Figure 8 is an enlarged view of the periphery of post 240A according to a second embodiment of the present invention. Referring to Figure 8, a substrate fixing member 260A is shown. Substrate fixing member 260A may be an example of a third member. Furthermore, substrate fixing member 260A may be provided in the fixing structure 30. Substrate fixing member 260A is positioned to restrict the movement of the substrate 10 away from the proximity surface 222 (Figure 3). The substrate fixing member 260A may be fixed to the upper surface 243A of post 240A by a fixing device 250A.

[0077] More specifically, the upper surface 243A of the post 240A may be provided with an insertion hole 242 into which a fixing device 250 is inserted. The fixing device 250 may then be inserted into the insertion hole 242 through a hole (not shown) provided in the substrate fixing member 260A and fixed to the post 240A. For example, if the height of the post 240A is adjusted in advance so that the lower surface of the substrate fixing member 260A and the upper surface of the substrate 10 are in contact, the substrate 10 can be fixed more strongly by the substrate fixing member 260A. For example, even if the substrate 10 is subjected to a strong impact, the substrate fixing member 260A will hold the substrate 10 in place, reducing the possibility that the substrate 10 will come off the fixing member 220.

[0078] Figure 8 shows an example in which the substrate fixing member 260A is fixed to post 240A. However, similar to the example in which the substrate fixing member 260A is fixed to post 240A, a substrate fixing member (not shown) may be fixed to post 240B. Alternatively, the substrate fixing member 260C (Figure 9) may be fixed to post 240C, or the substrate fixing member 260D (Figure 10) may be fixed to post 240D.

[0079] Figure 9 is an enlarged view of the area around the post 240C according to a second embodiment of the present invention. Referring to Figure 9, a substrate fixing member 260C is shown. The substrate fixing member 260C may be an example of a third member. The substrate fixing member 260C may be fixed to the upper surface (not shown) of the post 240C by a fixing device 250C, similar to the substrate fixing member 260A. In the example shown in Figure 9, the lower surface of the substrate fixing member 260C is in contact with the upper surface of the component 120D provided on the substrate 10, and the substrate 10 is more strongly fixed by the substrate fixing member 260C.

[0080] Furthermore, the substrate fixing member 260C may be configured to accommodate clamps 32 for bundling the wiring 34 connected to the substrate 10. Specifically, the substrate fixing member 260C may have a mounting portion 262C to which clamps 32 can be attached. This allows clamps 32 to be attached to the mounting portion 262C, and the wiring 34 to be bundled by the clamps 32. In addition, even when multiple wirings 34 are connected to the substrate 10, the substrate fixing member 260C takes on the role of securing the multiple wirings 34, eliminating the need to secure space for securing the multiple wirings 34 in a location other than the substrate fixing member 260C.

[0081] For example, the mounting portion 262C may have an annular shape, and the clamp 32 may be attached to the mounting portion 262C by wrapping the clamp 32 around the annular mounting portion 262C. The substrate fixing member 260C to which the clamp 32 can be attached is also called a "wire saddle".

[0082] Figure 10 is a magnified view of the area around the post 240D according to a second embodiment of the present invention. Referring to Figure 10, a substrate fixing member 260D is shown. The substrate fixing member 260D may correspond to an example of a third member. The substrate fixing member 260D may be fixed to the upper surface (not shown) of the post 240D by a fixing device 250D, similar to the substrate fixing member 260D. In the example shown in Figure 10, the lower surface of the substrate fixing member 260D is in contact with the upper surface of the component 120E on the substrate 10, and the substrate 10 is more strongly fixed by the substrate fixing member 260D.

[0083] Furthermore, the substrate fixing member 260D may have a flat plate shape. This increases the contact area between the substrate fixing member 260D and the substrate 10, allowing the substrate fixing member 260D to fix the substrate 10 more firmly. In addition, the substrate fixing member 260D may be made of a metal material and be electrically connected to the component 120E by contacting the component 120E.

[0084] Figure 11 is a side view of the substrate fixing member 260D as seen along direction A shown in Figure 10. Referring to Figure 11, the substrate fixing member 260D is in contact with and electrically connected to the component 120E. For example, as shown in Figure 11, the component 120E may be a connector. The electrical connection between the substrate fixing member 260D and the component 120E makes it possible to transfer the electricity accumulated on the substrate 10 to the component placement plate 210 along direction D1 (i.e., via the component 120E, the substrate fixing member 260E, and the post 240D).

[0085] (2.4. Effects) As described above, the second embodiment of the present invention can achieve the same effects as the first embodiment. Furthermore, according to the second embodiment of the present invention, the substrate 10 can be more firmly fixed by the substrate fixing member 260A fixed to the upper surface 243A of the post 240A. Furthermore, as described above, the substrate fixing member 260A can be appropriately deformed into shapes having various characteristics, such as substrate fixing member 260C or substrate fixing member 260D.

[0086] The second embodiment of the present invention has been described above.
