Description

  The present invention relates to a fixing mechanism for fixing a desired configuration, an optical apparatus including the fixing mechanism, and a fixing method.

  Conventionally, various configurations have been used as fixing mechanisms for optical members and the like.

  For example, Patent Document 1 uses a base bracket provided with a positioning member in order to fix the optical member at a predetermined position on the base bracket, and an engagement member for inserting a locking member into the positioning member. A fixing mechanism provided with a stop hole is described. Specifically, in this fixing mechanism, the positioning member is provided on the bake member so as to stand upright along the side of the plate-like optical member to be fixed. The positioning member is provided with a locking hole, and the optical member is fixed between the locking member and the base bracket by inserting and fixing the locking member into the locking hole. Since the positioning member needs a certain width to fix the locking member, it is necessary to provide a wide frame.

  Further, Patent Document 2 describes a fixing device that uses a panel presser fixed so as to cover an outer region of the display panel in order to fix the display panel at a predetermined position on the printed circuit board. . Specifically, this fixing device fixes the display panel at a predetermined position on the printed circuit board by inserting a locking claw into a hole provided in the side surface of the panel pressing member.

  Patent Document 3 describes a backlight assembly in which the backlight assembly is fixed to an external case. Specifically, the backlight assembly is provided with a hole on a side surface, and the backlight assembly is fixed to the outer case by inserting a screw into the hole.

Japanese Patent Laid-Open No. 10-312161 (published on November 24, 1998) Japanese Utility Model Publication No. 5-38629 (published May 25, 1993) JP 2003-346536 A (published on December 5, 2003)

  However, the conventional techniques as described above cannot stably fix a fixed object represented by an optical member or the like, and cannot reduce a frame formed so as to protrude around the fixed object. Has the problem.

  Specifically, in the technique described in Patent Document 1 described above, the positioning member needs to be thick, and as a result, there is a problem that the frame surrounding the periphery of the optical member cannot be reduced.

  Moreover, since the technique described in Patent Document 2 described above cannot make the fitting portion that fixes the display panel incorporated in the panel holding frame into a strong structure, it may be caused by an impact during transportation or use. There is a problem that the fitting is easily disengaged.

  Further, in the technique described in Patent Document 3 described above, the screw is inserted into a hole provided in the side surface of the backlight assembly, so that the screw does not damage the internal structure of the backlight assembly. The frame surrounding the periphery of the backlight assembly needs to be wide. Since the screw is inserted into a hole provided in the side surface of the backlight assembly, there is a problem that the force for fixing the backlight assembly cannot be made uniform and large.

  The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to stably fix a fixed object and to reduce a frame formed so as to protrude around the fixed object. An object of the present invention is to provide a fixing mechanism that can be used, an optical apparatus including the fixing mechanism, and a fixing method.

  In order to solve the above problems, the fixing mechanism of the present invention includes a plate-shaped member, an internal frame disposed on the back surface side of the plate-shaped member, at least a part of an outer peripheral portion of the plate-shaped member, and an internal frame. A fixing mechanism for fixing an external frame provided to cover at least a part of the plate-like member, the internal frame, and the external frame as a unit by connecting to the external frame. The fixing means is fixed to the inner frame on the back surface side of the inner frame, which is the side opposite to the side on which the plate-like member is disposed. The fixing means has elasticity, and fixes the outer frame while applying a force toward the back side of the inner frame to the outer frame. It is characterized in that.

  According to the above configuration, the fixing means is not fixed to the front surface side (side on which the plate-like member is provided) of the inner frame, which is opposite to the back surface side of the inner frame, and therefore the fixing means is provided on the front surface side. There is no need to secure space for. As a result, the frame, which is an area surrounding the plate-like member, can be reduced. In other words, according to the above configuration, the space in the inner frame can be expanded in the lateral direction (the area of the inner frame parallel to the front surface and the back surface). When various configurations are to be arranged, the degree of freedom of the arrangement can be increased.

  Further, since the fixing means is not provided on the side surface side of the inner frame, it is not necessary to secure a space on the side surface of the inner frame for inserting a screw or the like for fixing the fixing means from the side surface side. . As a result, the frame, which is an area surrounding the plate-like member, can be reduced. In other words, according to the above configuration, the space in the inner frame can be expanded in the lateral direction (the area of the inner frame parallel to the front surface and the back surface). When various configurations are to be arranged, the degree of freedom of the arrangement can be increased.

  Further, the fixing means is fixed to the back side of the inner frame, which is the side opposite to the side on which the plate-like member is disposed, so that a force directed from the front side of the inner frame to the back side is effective against the outer frame. Can be granted. As a result, the external frame provided so as to cover the outer periphery of the plate-like member can effectively generate a force for pressing the plate-like member, and each component can be stably fixed.

  In addition, since the fixing means has elasticity, it is possible to further increase the force with which the external frame presses the plate-like member, and to prevent an excessively large force from being applied to the plate-like member. it can.

  In the fixing mechanism of the present invention, the fixing means includes an elastic portion that applies an elastic force to the fixing means, a fixing portion that is fixed to the back surface of the inner frame, and a latch that is fixed to the outer frame. It is preferable that it is provided with the latching | locking part.

  According to the above configuration, since the fixing means includes the elastic portion, a moderately large force can be applied to the external frame.

  In addition, since the fixing means is detachably locked to the external frame via the locking portion, the connection state between the fixing means and the external frame can be easily released and returned to the connection state. Can do. As a result, various devices including the fixing mechanism of the present invention can be easily disassembled and assembled, and the device can be easily produced and repaired.

  Further, since the fixing means is fixed to the back surface of the inner frame via the fixing portion, the fixing means and the inner frame are integrated even when the connection state between the fixing means and the outer frame is released. That is, according to the above configuration, it is possible to prevent each component from being disassembled more than necessary, and as a result, it is possible to easily disassemble and assemble various devices including the fixing mechanism of the present invention. The production and repair of the equipment can be easily performed.

  In the fixing mechanism of the present invention, it is preferable that the locking portion is a projecting member, and the outer frame includes a hole for inserting the projecting member.

  According to the above configuration, the fixing means can be locked to the external frame with a simple configuration.

  In the fixing mechanism of the present invention, it is preferable that the locking portion includes a hole, and the external frame includes a protruding member for insertion into the hole.

  According to the above configuration, the fixing means can be locked to the external frame with a simple configuration.

  In the fixing mechanism of the present invention, the elastic part is preferably a plate-like spring member or a linear spring member.

  According to the said structure, the force which goes to the back surface side of the said internal frame can be provided with respect to the said external frame with a simple structure.

  In the fixing mechanism of the present invention, the elastic portion includes a plate-like or linear first region and a plate-like or linear second region connected to the first region, and the back side of the inner frame. The first area is arranged along the back surface of the internal frame when the fixing means is fixed to the back surface side of the internal frame, and the second area Is preferably connected to the first region so as to bend in a direction away from the back surface of the internal frame when the fixing means is fixed to the back surface side of the internal frame. .

  According to the above configuration, the elasticity of the elastic portion can be easily increased by the first region and the second region.

  Specifically, when a force (for example, a force applied to the fixing means when connecting the fixing means and the outer frame) is applied to the second region from the back side to the front side of the inner frame, The second region repels the force and tries to maintain a bent state. And the force which maintains the bent state can be utilized as elasticity of an elastic part.

  In the fixing mechanism of the present invention, the elastic portion is formed by connecting a plurality of linear members to each other so as to be bent, and is disposed on a side surface of the external frame. It is preferable that the outer frame is locked to the outer frame on the side surface.

  According to the said structure, the elasticity of an elastic part can be easily raised with a some linear member.

  Specifically, for linear members connected to each other so as to be bent, a force from the back side of the inner frame toward the front side (for example, when the fixing unit and the outer frame are connected to the fixing unit) When the applied force) is applied, the linear members connected to each other repel the force and try to maintain a bent state. And the force which maintains the bent state can be utilized as elasticity of an elastic part.

  In the fixing mechanism of the present invention, the elastic portion is a plate-like member disposed so as to reach the surface side of the internal frame from the back surface side of the internal frame, and the locking portion is a surface of the internal frame. It is preferable that the outer side is locked to the outer frame.

  According to the said structure, an elastic part is provided so that a part of surface of an internal frame, the side surface of an internal frame, and a part of back surface of an internal frame may be covered. That is, an elastic portion having a “U” shape is used. If it is an elastic part having the shape, since it is in contact with both the outer frame provided on the front side of the inner frame and the back side of the inner frame, a force toward the rear side of the inner frame is applied to the outer frame. Can be effectively applied. As a result, each component can be fixed stably.

  In the fixing mechanism of the present invention, the plate member is preferably an optical panel.

  According to the said structure, while being able to fix an optical panel stably by a simple structure, a frame can be made small.

  In order to solve the above-described problems, an optical apparatus according to the present invention includes the fixing mechanism according to the present invention.

  According to the said structure, the frame of an optical instrument can be made small. In other words, the ratio of the portion of the surface of the optical device where the optical panel is exposed on the surface can be increased.

  In addition, since the fixing mechanism of the present invention has little influence on the internal structure of the optical device, it is possible to increase the degree of freedom of arrangement of various configurations in the optical device.

  According to the present invention, there is an effect that each configuration including a plate-like member (particularly, a plate-like member) can be stably fixed.

  Moreover, there exists an effect that a frame can be made small.

  In addition, the internal space of the internal frame can be secured widely, and when various configurations are arranged in the internal space, it is possible to increase the degree of freedom of the arrangement.

  In addition, each configuration can be easily fixed, and the fixed configuration can be easily de-fixed.

  In addition, it is possible to increase the productivity of various devices that require fixing and defixing of each component in the manufacturing process.

  Further, in the repair process, it is possible to quickly and easily repair various devices that require the fixing and defixing of each component.

It is a schematic diagram which shows the fixing method using the fixing mechanism shown in FIG. It is a schematic diagram which shows one Embodiment of the optical instrument in this invention.

  An embodiment of the present invention will be described below with reference to FIGS. 1 to 8, but the present invention is not limited to this.

[1] Fixing Mechanism As shown in FIGS. 1 to 7, the fixing mechanism of the present embodiment is arranged on the plate-like member 2 and the back side of the plate-like member 2 using the fixing member 1 (fixing means). The internal frame 5 and the external frame 10 provided so as to cover at least a part of the outer peripheral portion of the plate-like member 2 and at least a part of the internal frame 5 are integrally fixed. Each configuration will be described below.

  The shape of the plate-like member 2 may be a plate shape, and the detailed shape is not particularly limited. For example, a circular plate, a square plate, or the like can be used, but it is not limited to these. Moreover, the thickness of the said plate-shaped member 2 is not specifically limited, The plate-shaped member 2 which has desired thickness suitably can be used.

  Although it does not specifically limit as a more specific structure of the said plate-shaped member 2, For example, it is preferable that it is an optical panel. More preferable configurations of the optical panel include a liquid crystal panel, a plasma panel, an EL (electroluminescence) panel, and the like, but are not limited thereto. If it is the said structure, while an optical panel is fixed stably, an optical apparatus with a high area ratio by which an optical panel is exposed on the surface, in other words, an optical apparatus with a small frame can be produced. In the following embodiment, the “frame” is intended to be an area formed so as to protrude from the periphery of the plate-like member 2 when the respective components are integrally fixed. In other words, the “frame” means that the configuration (for example, the surface of the external frame 10) other than the plate-like member 2 is the surface when the integrated state of each component is observed from the surface side of the plate-like member 2. An area that is exposed to is intended.

  An inner frame 5 is disposed on the back side of the plate-like member 2. In other words, the plate-like member 2 is arranged on the surface side of the inner frame 5. The details of the arrangement of the plate-like member 2 and the inner frame 5 are not particularly limited. For example, the plate-like member 2 may be disposed on the surface of the internal frame 5, or the plate on the surface of the internal frame 5 so that the surface of the internal frame 5 and the surface of the plate-like member 2 are flush with each other. It is also possible to provide a hole for fitting the shaped member 2.

  The plate-like member 2 is preferably arranged on the surface side of the inner frame 5 by meshing with an end portion of the inner frame 5 described later. More specifically, the shape of the end portion of the plate-like member 2 is preferably a multistage shape that meshes with the end portion of the inner frame 5. According to the said structure, the plate-shaped member 2 can be fixed more stably. Moreover, according to the said structure, since the surface of the plate-shaped member 2 and the surface of the internal frame 5 can be arrange | positioned on the same plane, the thickness of the surface side of the internal frame 5 can be made thin.

  The internal frame 5 may be composed of a single integrated structure, or may be composed of a plurality of structures. For example, as shown in FIGS. 1, 2, 4, and 6, the internal frame 5 includes a side frame 6 that forms the side surface of the internal frame 5, and a back frame 7 that forms the back surface of the internal frame 5. It is preferable. If the internal frame 5 is formed as one integrated structure, it is possible to prevent each structure from being unnecessarily disassembled when the fixed state of each structure is released. On the other hand, if the inner frame 5 is formed as a separate configuration, each configuration can be sufficiently disassembled when the fixed state of each configuration is released. Therefore, a preferable inner frame 5 may be used depending on the purpose. If it is this invention, even if it is the internal flame | frame 5 which consists of a some structure, each structure can be fixed stably.

  The shape of the inner frame 5 is not particularly limited. For example, a cylindrical box or a quadrangular prism box that can have various configurations inside is preferable. More specifically, the internal frame 5 is preferably a frame for providing an optical panel.

  The shape of the side frame 6 and the back frame 7 is not particularly limited as long as it is the shape of the internal frame 5 when combined.

  Although it does not specifically limit as a shape of the said side surface frame 6, For example, it is preferable that it is a cylindrical shape. More specifically, a cylindrical tube, a square columnar tube, and the like can be given, but the invention is not limited to these.

  The size and shape of the back frame 7 are not particularly limited, but are preferably, for example, a size and shape (for example, a circle or a quadrangle) that can be supported by the bottom side end of the side frame 6. According to the said structure, the internal frame 5 which consists of a some structure can be fixed more stably.

  The side frame 6 can also define the shape of the surface side of the inner frame 5. In other words, the side frame 6 can also extend to the surface side of the inner frame 5, and the region of the side frame 6 that extends to the surface side of the inner frame 5 forms the surface of the inner frame 5. obtain. The shape and area of the region of the side frame 6 extending to the surface side of the inner frame 5 are not particularly limited, but the smaller the area, the better. In other words, according to the present invention, the area of the side frame 6 extending to the surface side of the inner frame 5 can be made as small as possible. As a result, the frame can be reduced.

  It is preferable that a hole for fitting the plate-like member 2 is formed in a region of the side frame 6 extending to the surface side of the inner frame 5 (in other words, the surface side of the frame 5). Furthermore, it is preferable that the end of the hole has a multi-stage shape that allows the plate-like member 2 to be disposed on the surface side of the inner frame 5 by meshing with the end of the plate-like member 2. According to the said structure, the plate-shaped member 2 can be fixed more stably. Moreover, according to the said structure, since the surface of the plate-shaped member 2 and the surface of the internal frame 5 can be arrange | positioned on the same plane, thickness of various apparatuses provided with the fixing mechanism of this invention can be made thin. it can.

  The inner frame 5 is preferably provided with a protrusion 50 for detachably locking an outer frame 10 described later. The position at which the protrusion 50 is provided is not particularly limited, but is preferably provided on the side frame 6 (in other words, on the surface or side surface of the internal frame 5) from the viewpoint of more stably fixing each component. It is further preferable to be provided on the region of the side frame 6 extending to the surface side of the inner frame 5 (in other words, on the surface of the inner frame 5). The outer frame 10 to be described later is provided with a hole 51 into which the protrusion 50 is inserted in a region where the outer frame 10 is disposed so as to overlap the protrusion 50. By providing the protrusions 50 and the holes 51 as described above, the respective components can be stably fixed and the respective components can be easily disassembled.

  The outer frame 10 is provided so as to cover at least a part of the outer peripheral portion of the plate-like member 2 and at least a part of the inner frame 5. At this time, the region of the external frame 10 covering at least a part of the outer peripheral portion of the plate-like member 2 presses the plate-like member 2, whereby each configuration including the plate-like member 2 is stably fixed. It will be.

  Although the outer peripheral part of the said plate-shaped member 2 intends the area | region of the outer side of the plate-shaped member 2 containing the edge part of the plate-shaped member 2, the area | region is not specifically limited. With the fixing mechanism according to the present embodiment, each configuration can be stably fixed even on the outer peripheral portion having a small area.

  The outer frame 10 can cover the entire outer periphery (in other words, it can also cover the outer periphery of the plate-like member 2), or a part of the outer periphery. It is also possible to cover. From the viewpoint of fixing each component more stably, it can be said that the outer frame 10 preferably covers the entire outer peripheral portion. When a part of the outer peripheral portion is covered by the outer frame 10, it is preferable that the outer frame 10 covers an outer peripheral portion region that exists at a symmetric position with respect to the center point of the plate-like member 2. According to the said structure, since the symmetrical area | region in the plate-shaped member 2 is pressed, the plate-shaped member 2 can be fixed stably.

  The specific shape of the outer frame 10 is not particularly limited. For example, a plate shape that can be disposed along the surface and side surfaces of the inner frame 5 is preferable. According to the said structure, each structure can be fixed more stably. When the outer frame 10 is formed in a plate shape, the outer frame 10 can be formed so as to cover the entire side surface of the inner frame 5, or only a specific surface among the side surfaces of the inner frame 5. Although it is possible to form the external frame 10 so as to cover, the present invention is not limited to this configuration.

  In the fixing mechanism of the present embodiment, the fixing member 1 having elasticity is connected to the external frame 10. And the fixing member 1 is the side opposite to the side on which the plate-like member 2 is arranged, with the force toward the back side of the inner frame 5 being applied to the outer frame 10 by the fixing member 1. The inner frame 5 is fixed to the back surface (for example, the back frame 7). As a result, the fixing member 1, the plate-like member 2, the inner frame 5 and the outer frame 10 are integrally fixed.

  The fixing member 1 includes a fixing portion 15 that is fixed to the back surface of the inner frame 5, a locking portion 16 that is locked to the outer frame, and an elasticity that provides an elastic force to the fixing member 1. Part 17. Each configuration will be described below.

  The fixing portion 15 is fixed to the back surface of the internal frame 5, whereby the fixing member 1 is fixed to the back surface of the internal frame 5.

  The specific configuration of the fixing portion 15 is not particularly limited, and a known configuration can be used as appropriate.

  For example, the fixing portion 15 includes a screw hole (see FIGS. 1, 4 and 5) provided in a plate-like member, a linear member (see FIGS. 2 and 3) that can be locked to the back frame 7, Alternatively, it may be a screw hole (see FIGS. 6 and 7) provided in a linear member, but is not limited to this configuration. In consideration of the degree of freedom of arrangement of various configurations arranged in the space in the inner frame 5, the fixing portion 15 is preferably a linear member that can be locked to the back frame 7. I can say that. If it is the said structure, while it is not necessary to provide a screw hole etc. in the back surface of the internal frame 5, and a screw is not inserted in the internal frame 5 through the said screw hole, the space in the internal frame 5 is made. Can be wide. As a result, the degree of freedom of arrangement of various configurations arranged in the space in the internal frame 5 can be increased.

  When a screw hole provided in a plate-like member is used as the fixing portion 15, it is preferable to provide a slit in the plate-like member provided with a screw hole, as shown in FIGS. In addition, although the shape of the said slit is not specifically limited, For example, it is preferable that it is a concave shape. By providing the slit, it is possible to prevent a gap from being generated between the inner frame 5 and the fixing portion 15, and as a result, the fixing portion 15 can be firmly fixed to the back surface of the inner frame 5.

  When a linear member that can be locked to the back frame 7 is used as the fixing portion 15, as shown in FIG. 3, the linear shape is attached to the back frame 7 (in other words, the back surface of the internal frame 5). It is preferable that a protrusion 52 for locking the member is provided. In this case, the protrusion 52 is provided with a screw hole 37 for further firmly fixing the locked linear member. May be. By providing the protrusion 52, the fixing portion 15 can be firmly fixed to the inner frame 5. Further, as shown in FIG. 3, by inserting the screw 36 of the screw hole 37, the fixing portion 15 locked to the back frame 7 can be fixed more firmly.

  The locking portion 16 is detachably locked to the external frame 10.

  The locking portion 16 may be any as long as it can be detachably locked to the external frame 10, and its specific configuration is not particularly limited.

  For example, the locking portion 16 is preferably a protruding member. In this case, the outer frame 10 is preferably provided with a hole for inserting and locking the protruding member.

  The shape and size of the protruding member are not particularly limited, and may be a desired shape and size as appropriate.

  For example, as shown in FIG. 1, the locking portion 16 is preferably a plate-like protrusion-like member connected to a plate-like member provided with the fixing portion 15. In this case, the outer frame 10 is provided with a hole 53 having a shape and a size capable of locking the locking portion 16. The shape and size of the hole 53 are not particularly limited, and can be formed in a desired shape and size according to the size and shape of the locking portion 16. The position in the outer frame 10 where the hole 53 for locking the locking portion 16 is provided is not particularly limited. For example, as shown in FIG. More preferably, it is a place where the outer frame 10 is in contact with or near the place. According to the above configuration, the locking portion 16 having a simple shape can be locked to the external frame 10.

  For example, as shown in FIGS. 2, 3, 6, and 7, the locking portion 16 may be a linear protruding member connected to the fixing portion 15. In this case, the outer frame 10 is provided with a hole 53 having a shape and a size capable of detachably locking the linear projecting member. The shape and size of the hole 53 are not particularly limited, and can be formed in a desired shape and size according to the size and shape of the locking portion 16. The position in the external frame 10 where the hole 53 for locking the locking portion 16 is provided is not particularly limited. For example, as shown in FIGS. 2 and 3, the hole 53 is provided on the side surface of the external frame 10. It is preferred that Further, as shown in FIGS. 6 and 7, the hole 53 is preferably provided at an end portion of the side surface of the external frame 10 that is disposed on the back frame 7 side. According to the above configuration, a force toward the back side of the internal frame 5 can be easily applied to the frame 10.

  The locking portion 16 may have a configuration other than the protruding member as described above. For example, the locking portion 16 may be a hole. In this case, the outer frame 10 is preferably provided with a protruding member for insertion into the hole.

  The shape and size of the protruding member and hole are not particularly limited, and may be a desired shape and size as appropriate.

  Further, the position at which the protruding member and the hole are provided is not particularly limited, and can be appropriately provided at a desired position. For example, as shown in FIG. 4, the protruding member is preferably provided on the surface side of the outer frame 10. In this case, the hole is provided in a region in the outer frame 10 that is disposed so as to overlap the protruding member. According to the above configuration, a force toward the back side of the internal frame 5 can be easily applied to the frame 10.

  Next, the elastic part 17 will be described.

  The elastic portion 17 is configured to give elasticity to the fixing member 1. Then, due to the elasticity generated by the elastic portion 17, the fixing member 1 can apply a force toward the back side of the inner frame 5 to the outer frame 10.

  Of course, it is also possible to give elasticity to the fixing member 1 by forming the fixing member 1 using a material having high elasticity. In this case, for example, the whole or a part of the fixing member 1 functions as the elastic portion 17. Although it does not specifically limit as a raw material with high elasticity, For example, it is preferable to use a metal, resin, rubber | gum, etc.

  Although the specific structure of the said elastic part 17 is not specifically limited, For example, it is preferable that it is a spring. Although it does not specifically limit as a specific structure of a spring, For example, it is preferable that it is a plate-shaped spring member or a linear spring member. According to the above configuration, the elastic portion 17 can be formed with a simple configuration. Although an example of a preferable spring is shown below, the present application is not limited to this.

  For example, in the configuration shown in FIG. 1, the elastic portion 17 is a plate-like spring member.

  The elastic portion 17 includes a plate-like first region and a plate-like second region connected to the first region, and is disposed on the back side of the internal frame 5. More specifically, the first region corresponds to the plate-like member 18 provided with the fixing portion 15, and the second region corresponds to the locking portion 16. The first region is arranged along the back surface of the internal frame 5 when the fixing member 1 is fixed to the back surface side of the internal frame 5. The second region is connected to the first region so as to bend in a direction away from the back surface of the internal frame 5 when the fixing member 1 is fixed to the back surface side of the internal frame 5. Then, the force for maintaining the bent shape can be used as the elasticity of the elastic portion 17. That is, in the present embodiment, the bent structure of the fixing member 1 functions as the elastic portion 17.

  Moreover, in the structure shown in FIG. 6 and FIG. 7, the elastic part 17 is a linear spring member.

  The elastic portion 17 includes a linear first region and a linear second region connected to the first region, and is disposed on the back side of the internal frame 5. More specifically, the first region corresponds to a linear member that forms the region 20 of FIG. 6, and the second region corresponds to a linear member that forms the region 21. The first region is arranged along the back surface of the internal frame 5 when the fixing member 1 is fixed to the back surface side of the internal frame 5.
