Summary of the Invention

Problems to be Solved by the Invention

[0004] The protective cover is distributed and sold as a structure (package) housed in a plastic package called a "blister pack" or "blister". A consumer who purchases the structure takes out the protective cover from the plastic package and attaches the taken-out protective cover to the mobile terminal.

[0005] Since the protective cover is small, when taking out the protective cover from the plastic package or attaching the taken-out protective cover to the mobile terminal, oil and dirt on the fingertips are likely to adhere to the protective cover. Adhesion of oil and dirt to the protective cover must be suppressed as much as possible. When oil and dirt adhere to the transmissive glass of the protective cover, the image quality of the camera image deteriorates. The protective cover has an adhesive for attaching the protective cover to the camera unit, but when oil and dirt adhere to the adhesive, it causes a decrease in adhesive force.

[0006] The problem that this invention aims to solve is to prevent oil and dirt from adhering to the protective cover when it is removed from its plastic packaging and attached to a mobile device. [Means for solving the problem]

[0007] To solve the above-mentioned problems, the inventor devised the following mounting jig for a mobile device.

[0008] The configuration disclosed herein comprises a protective cover for covering a camera portion located on the back of a mobile device, and a plastic packaging for housing the protective cover, The aforementioned plastic packaging is The back surface of the plastic packaging is provided with a recess for housing the protective cover, and the inner surface of the recess elastically holds the outer surface of the protective cover. The plastic packaging body has a protrusion on its surface corresponding to the recess, and when the protrusion is pressed, the elastic retention of the protective cover by the inner surface of the recess is released.

[0009] The most distinctive feature of the aforementioned configuration is that the plastic packaging used as a container for transporting the protective cover also serves as a mounting jig for attaching the protective cover to a mobile device. Conventionally, it was necessary to remove the protective cover from the plastic packaging and then attach it to the camera unit by pinching it with your fingertips. However, with the aforementioned configuration, the protective cover can be attached to the camera unit without touching it, by placing the plastic packaging, along with the protective cover itself, onto the camera unit located on the back of the mobile device, without removing the protective cover from the plastic packaging. This prevents oil and dirt from adhering to the protective cover. The "camera unit located on the back of the mobile device" that the protective cover covers is usually the final optical element (lens or glass plate) in the camera unit.

[0010] As will be explained in more detail later, when attaching the protective cover to the camera using plastic packaging, the protective cover must not fall off the plastic packaging. Therefore, the plastic packaging is designed to elastically hold the protective cover until it is attached to the camera, at which point the elastic holding force is released and the protective cover loses its holding power, thus preventing the protective cover from falling off the plastic packaging when it is attached to the camera.

[0011] In the above-mentioned structure, the plastic packaging body may have a projection on its inner surface that protrudes toward the protective cover. The protrusions contact the outer periphery of the protective cover, generating friction that allows the protective cover to be elastically held in place. Furthermore, because the protrusions flex with relatively little force, when pressing the protrusions from the surface to release the elastic holding of the protective cover, only a small amount of pressure is required.

[0012] In the above-described structure, the plastic packaging does not necessarily have a protrusion. If the recess of the plastic packaging has an inner diameter substantially the same as the outer diameter of the protective cover, the inner wall of the recess will come into surface contact with the outer periphery of the protective cover, generating friction. As a result, the recess of the plastic packaging can elastically hold the protective cover. Furthermore, if a protrusion is pressed from the surface of the plastic packaging, even in a configuration without a protrusion, the surface contact between the recess of the plastic packaging and the outer periphery of the protective cover will be released, and the elastic holding will be released.

[0013] In the above configuration, a protective cover covers N (N: a natural number from 1 to 5) of the camera units, The plastic packaging may also include a plastic packaging having N recesses on its back surface and N protrusions on its surface, each corresponding to one of the N recesses. Furthermore, when the plastic packaging is viewed from the surface, the positional relationship between the protrusions may be the same as the positional relationship between the camera parts of the mobile terminal. Since the N protective covers are housed in the plastic packaging in a relative position, the N protective covers can be attached simultaneously and all at once.

[0014] In the above-mentioned structure, a bump guide is provided around the recess on the back surface, The bump guide may correspond to camera bumps positioned around the camera on the back of the mobile device. By positioning the plastic packaging relative to the mobile device so that the bump guide overlaps the protruding area of ​​the mobile device, the protective cover can be accurately positioned relative to the camera.

[0015] In the above-mentioned structure, the plastic packaging may have straight side edges and a straight upper edge. Furthermore, the side edges of the plastic packaging may overlap with the side edges of the mobile device, and the top edge of the plastic packaging may overlap with the top edge of the mobile device. This allows the plastic packaging to perform an alignment function relative to the mobile device.

[0016] In the above-described structure, the depth of the recess in the plastic packaging may be less than the thickness of the protective cover. This allows the protective cover to come into contact with the mobile device when the plastic packaging is placed on the mobile device.

[0017] The aforementioned structure may include a base material portion that contacts the back surface of the plastic packaging. Furthermore, the protective cover may be sandwiched between the base material and the plastic packaging.

[0018] In the above-mentioned structure, the base material portion may have a notch that sandwiches at least a portion of the flange of the plastic packaging body. The flange can be held in place by sliding under the notch.

[0019] The plastic package includes a convex guide around the convex portion on the surface. The convex guide may be in a state of being inserted from the notch. The convex guide assists in inserting the plastic package in an appropriate direction with respect to the base material portion.

[0020] The component may further include a label describing at least one of the brand name and model name of the mobile terminal. In the component, the label may be provided on the base material portion or on the plastic package. When the base material portion is hard paper, the label may be printed on the hard paper.

[0021] In the component, the protective cover may have a mount attached to the back surface of the mobile terminal and a cover body connected to the mount so as to be openable and closable. Furthermore, the plastic package may accommodate the mount and the cover body in the recess in a closed state.

[0022] The protective cover may have an adhesive surface that can adhere to the camera portion and a release film in contact with the adhesive surface.

[0023] The shape of the corner portion formed by the linear side edge and the linear upper edge of the plastic package may match the shape of the corner portion of the mobile terminal.

Advantages of the Invention

[0024] When the protective cover is taken out from the component and attached to the mobile terminal, it is possible to suppress the adhesion of dust and oil stains to the protective cover.

[0026] The components of this invention will be described with reference to the drawings as appropriate. It should be noted that the drawings disclosed herein are for illustrative purposes only. That is, the dimensional ratios shown in the drawings do not necessarily correspond to the actual dimensional ratios, and the dimensional ratios do not necessarily correspond between the drawings.

[0027] In this specification, each embodiment is described using the XYZ Cartesian coordinate system. When expressing a direction, if positive and negative directions are distinguished, they are indicated with a sign, such as "+X direction" and "-X direction". When directions are expressed without distinguishing between positive and negative directions, they are simply described as "X direction". In other words, in this specification, when simply described as "X direction", both "+X direction" and "-X direction" are included. The same applies to the Y direction and Z direction.

[0028] <First Embodiment> [Constituent] A first embodiment of the structure according to the present invention will be described with reference to Figure 1. Figure 1 is a front view of the structure 100 as seen from its front side (the side with the protrusion of the blister 10, the +Z side). The structure 100 includes three protective covers (2a, 2b, 2c) for covering three camera sections located on the back of a mobile terminal, and a single blister 10 that houses the three protective covers (2a, 2b, 2c). The blister 10 functions as a container for transporting and displaying the protective covers (2a, 2b, 2c).

[0029] In this specification, mobile devices include smartphones, mobile phones other than smartphones, tablet computers, laptop computers, wearable devices such as smartwatches, and electronic devices with image sensors such as portable game consoles. The blister 10 is a flat plastic packaging that stretches along the XY plane and has its thickness in the Z direction. The protective covers (2a, 2b, 2c) are transported to retailers or consumers, or displayed for sale, while contained in the blister 10, and are therefore resistant to damage.

[0030] The component 100 of this embodiment further includes a base material 1 for fixing the blister 10. The protective covers (2a, 2b, 2c) are sandwiched between the blister 10 and the base material 1.

[0031] [Details of Blister] The details of blister 10 are described below. Since blister 10 itself is transparent, the protective covers (2a, 2b, 2c) can be seen through blister 10. Note that in Figure 1, the protrusions (11a, 11b, 11c) of blister 10 are located on the +Z side of the visible protective covers (2a, 2b, 2c).

[0032] The blister 10 uses a flexible resin material. The flexible resin material is a material that easily achieves both the rigidity necessary to maintain the elasticity of the protective covers (2a, 2b, 2c) and the flexibility that allows the elasticity of the protective covers (2a, 2b, 2c) to be released when the blister 10 is pressed.

[0033] Specifically, polyethylene terephthalate (PET), polypropylene (PP), or polyvinyl chloride (PVC) may be used for the blister 10. The term "plastic packaging" includes PET, PP, and PVC. In the case of polyethylene terephthalate (PET), amorphous A-PET is particularly preferred. The blister 10 is formed by imparting irregularities to a plastic sheet by vacuum forming, pressure forming, or injection molding. Vacuum forming is performed, for example, by placing a heated and softened plastic sheet on a mold and sucking air from below (creating a vacuum) to make the sheet adhere tightly to the mold. Pressure forming is performed by pressing the sheet against the mold by blowing compressed air from above in addition to vacuum suction.

[0034] The thickness of the blister pack 10 is preferably 0.05 mm to 1.00 mm, more preferably 0.10 mm to 0.80 mm, and more preferably 0.20 mm to 0.50 mm.

[0035] Figure 2A is a front view of the surface 10F of the blister 10, viewed from the +Z side in the -Z direction. Figure 2B is a cross-sectional view of Figure 2A along the line X1-X1. Figure 2C is a front view of the blister 10 alone, showing the back surface 10B of the blister 10 viewed from the -Z side in the +Z direction. Note that since Figures 2A and 2B show the front and back surfaces of the blister 10 viewed from opposite sides, the components are arranged in a mirror image. In addition to the blister 10, Figure 2B also shows the protective cover 2c housed within the blister 10.

[0036] Figure 2B shows that the surface 10F of the blister 10 has three protrusions (15c, 12, 12) projecting in the +Z direction from a reference position Z1 in the Z direction. The back surface 10B of the blister 10 has recesses (15c, 14, 14) corresponding to the three protrusions (15c, 12, 12). The central protrusion 11c on the surface 10F corresponds to the central recess 15c on the back surface 10B. The central recess 15c is used to accommodate the protective cover 2c. Figure 2C shows that the back surface 10B of the blister 10 has three recesses (15a, 15b, 15c) that accommodate the three protective covers (2a, 2b, 2c).

[0037] The recess 15a on the back surface 10B (see Figure 2C) corresponds to the protrusion 11a on the front surface 10F of the blister 10 (see Figure 2A). The recess 15b on the back surface 10B (see Figure 2C) corresponds to the protrusion 11b on the front surface 10F of the blister 10 (see Figure 2A). The recess 15c on the back surface 10B (see Figure 2C) corresponds to the protrusion 11c on the front surface 10F of the blister 10 (see Figure 2A).

[0038] In Figure 2B, the two protrusions on either side of the protrusion 11c are convex guides 12. As shown in Figure 2A, on the surface 10F, the convex guides 12 are formed in a rectangular ring shape, surrounding the three protrusions (11a, 11b, 11c) around their entire circumference. The back surface 10B has a concave portion 14 corresponding to the convex guides 12. The main function of the convex guides 12, which is guiding, will be described later, but the convex guides 12, which are formed in a ring shape as a whole, have the secondary function of improving the rigidity of the blister 10 as a container while maintaining the flexibility of the protrusions (11a, 11b, 11c).

[0039] In Figure 2A, the annular convex guide 12 has a roughly rectangular shape with rounded corners. However, the corners of the convex guide 12 do not have to be rounded. The annular convex guide 12 does not have to be roughly rectangular. Also, the convex guide 12 does not have to surround the convex parts (11a, 11b, 11c) all the way around. The convex guide 12 may be, for example, a linear guide extending in the Y direction.

[0040] The depth t2 of the recess 15c in the blister 10 (see Figure 2B) should be shallower than the thickness t3 of the protective cover 2c (see Figure 2B or Figure 3). In other words, when the protective cover 2c is placed in the recess 15c, it should protrude from the back surface 10B of the blister 10. This allows the protective cover 2c to come into contact with the mobile device when the blister 10 is placed on the mobile device. The depth t2 of the recess 15c should be, for example, 0.3 mm to 1.5 mm. Of course, the depth t2 of the recess 15c (see Figure 2B) may be the same as the thickness t3 of the protective cover 2c (see Figure 2B or Figure 3), or it may be deeper than the thickness t3.

[0041] In Figure 2B, the outer diameter d3 of the protective cover 2c is smaller than the inner diameter d2 of the recess 15c that accommodates the protective cover 2c. The same relationship exists between the outer diameters of the other protective covers (2a, 2b) and the inner diameters of the recesses (15a, 15b). Therefore, in Figure 2C, a gap is created between the recesses (15a, 15b, 15c) and the protective covers (2a, 2b, 2c). In Figure 2C, the protective covers (2a, 2b, 2c) are shown by dashed lines. The protective covers (2a, 2b, 2c) are held in place by projections 16 provided on the inner surfaces of the recesses (15a, 15b, 15c). Figure 2C shows how the three projections 16 provided on the inner surface of the recess 15c are in contact with the outer surface of the protective cover 2c. The three projections 16 press against the protective cover 2c, thereby supporting and fixing the protective cover 2c in place. Furthermore, similar to recess 15c, recesses (15a, 15b) also have protrusions.

[0042] The amount of protrusion of the protrusion 16 from the inner surface of the recess (15a, 15b, 15c) is preferably, for example, 0.05 mm or more and 0.3 mm or less. The width (dimension along the circumferential direction) of the protrusion 16 in contact with the protective cover (2a, 2b, 2c) is preferably 0.2 mm or more and 1 mm or less. When inserting the protective cover 2a into the recess 15c, the protrusion 16 makes point contact or line contact with the outer surface of the protective cover 2a while slightly elastically deforming. After insertion, the protective cover 2 is held in place by the frictional force of the protrusion 16 pressing against the protective cover (2a, 2b, 2c). It is preferable that multiple protrusions 16 are provided in the circumferential direction of the inner surface. In this embodiment, three protrusions are provided at equal intervals in the circumferential direction. Each protrusion 16 may be provided along the Z direction of the inner surface, or only in a part of the Z direction of the inner surface (for example, only near the reference position Z1).

[0043] [Details of the protective cover] Figure 3 shows the protective cover 2 and the camera unit 92 of the mobile terminal 90 separated. The camera unit 92 protrudes from the back surface 90B of the mobile terminal 90. For clarity, only a single camera unit 92 is shown in Figure 3. In reality, this embodiment includes a blister 10 corresponding to three camera units, as described above. At the frontmost edge of the camera unit 92 is an optical element 95 such as a glass plate or lens. The protective cover 2 covers the camera unit 92 (especially the frontmost optical element 95) located on the back surface 90B of the mobile terminal 90 from the outside. This prevents scratches and dirt from adhering to the camera unit 92.

[0044] The protective cover 2 includes a light-transmitting glass 20 (hatched area in Figure 3) and a cylindrical support portion 23. A circular light-transmitting glass 20 is fixed to the positional end of the cylindrical support portion 23. The light-transmitting glass 20 may be tempered glass, sapphire glass, or a light-transmitting rigid resin such as polycarbonate or acrylic. Furthermore, the light-transmitting glass 20 may not only transmit light but also have functions as a polarizing filter, ND filter, or infrared cut filter.

[0045] The portion of the light-transmitting glass 20 that contacts the camera unit 92 is coated with an adhesive (not shown) on the opaque portion at the periphery of the light-transmitting glass 20. The adhesive applied may be, for example, a silicone resin-based or acrylic-based adhesive. The thickness of the adhesive is preferably, for example, 10 μm or more and 100 μm or less.

[0046] In the direction indicated by arrow A1 in Figure 3, the protective cover 2 is moved to the camera section 92 of the mobile terminal 90, bringing the adhesive into contact with the area around the optical element 95, and the protective cover 2 is attached to the camera section 92. A release film (not shown in Figure 3) to protect the adhesive surface during distribution is attached to the adhesive of each protective cover 2.

[0047] [Details of the base material] The base material 1 will be described with reference to Figure 1. The base material 1 is a flat, sheet-like or plate-like object. The blister 10 is fixed to the base material 1 by a part of the back surface 10B of the blister 10 contacting one of the main surfaces of the base material 1. In the structure 100, the protective covers (2a, 2b, 2c) are positioned between the base material 1 and the blister 10.

[0048] In this embodiment, the base material 1 is formed from rigid paper (cardboard or cardboard) having sufficient rigidity to support the blister 10. In particular, in this embodiment, the base material 1 is constructed by laminating multiple sheets of rigid paper. Of the laminated rigid paper, the rigid paper closest to the blister 10 has an opening and a notch 21 (see Figure 1) for fitting the blister 10. The other laminated rigid paper does not have an opening and a notch 21 for fitting the blister 10. Note that the base material 1 is not limited to rigid paper, and may be, for example, a plastic sheet or a metal plate.

[0049] The blister 10 is inserted into a notch 21 formed in the base material 1, with a portion of the flange 13 of the blister 10 being inserted. The flange 13 slides under the notch 21, allowing the blister 10 to be held in place by the base material 1. The flange 13 is provided so as to extend in the Y direction on both sides of the blister 10 in the X direction. If the blister 10 has a convex guide 12, the flange 13 is located outside the convex guide 12 in the X direction. The convex guide 12 assists in ensuring that the blister 10 is inserted in the correct direction. In Figure 1, the lower edge of the blister 10 and the side edges of the blister 10 that constitute the flange 13 are shown as dashed lines.

[0050] The method of inserting the blister 10 into the notch 21 and fixing the blister 10 to the base material 1 is excellent from the standpoint of reducing environmental impact, as it reduces the amount of adhesive used and facilitates recycling by easily separating the plastic and paper. It is also excellent from the standpoint of convenience, as when a user opens the assembly 100, they can separate the blister 10 from the base material 1 simply by sliding the blister 10 against the base material 1. In addition, to prevent the blister 10 from sliding out of the notch 21 in the base material 1, the blister 10 may be secured to the base material 1 using adhesive tape or the like.

[0051] The surface of the base material 1 is printed with a mark 5 indicating that it is a component suitable for a specific mobile device model or brand. In Figure 1, the mark 5 reads "For X phone," indicating that the component 100 is suitable for the model name and brand "X phone." Since the size, number, and positional relationship of the camera unit 92 differ depending on the brand name and model, the component 100 is prepared for each brand name and model. Note that the name "X phone" is a hypothetical brand name and model shown as an example and is unrelated to actual brand names and models. Because the component 100 has the mark 5, users who purchase the component 100 can recognize that it is suitable for the model name or brand called "X phone." In this embodiment, the mark 5 is printed on the base material 1 (hard paper), but the blister pack 10 may also show the mark 5. In addition, a through hole 22 is provided at the top of the base material 1 for passing a hook through to hang the component 100 from a display fixture in a retail store.

[0052] [How to attach the protective cover] In this embodiment, a blister pack 10 is used to simultaneously attach three protective covers 2 to three camera units. The method of attaching the protective covers 2 will be explained with reference to Figures 4A to 4D.

[0053] Figure 4A shows the three camera units (92a, 92b, 92c) and their surroundings on the mobile terminal 90. The three camera units (92a, 92b, 92c) protrude from the back of the mobile terminal 90. Before attaching the protective cover 2, remove any dust and dirt from around the camera units (92a, 92b, 92c).

[0054] Figure 4B shows the removal of the release film 31 protecting the adhesive. With the back surface 10B of the blister 10 facing you, remove the release film 31 attached to the adhesive of each protective cover (2a, 2b, 2c) without removing the protective covers (2a, 2b, 2c) from the blister 10. Each release film 31 has a tab 32 for peeling off the release film 31. By holding the blister 10 with one hand and pinching and pulling the tab 32 with the other hand, the release film 31 can be peeled off without touching the protective covers (2a, 2b, 2c). Note that the release film 31 can have any configuration. In this embodiment, a release film is attached to each of the three protective covers (2a, 2b, 2c), but a common release film may be attached to cover multiple protective covers (2a, 2b, 2c).

[0055] Figure 4C shows the process of moving the blister pack 10 so that its surface 10F, with the release film removed from the protective cover 2, faces forward, in order to place the blister pack 10 on top of the camera section (92a, 92b, 92c). The three protective covers 2 are moved above the camera section (92a, 92b, 92c) along with the blister pack 10 in the direction indicated by arrow A2 in Figure 4C.

[0056] As described above, the outer diameter d3 of the protective cover (2a, 2b, 2c) in this embodiment is smaller than the inner diameter d2 of the recess 15 corresponding to the convex portion 11c. In this situation, if the blister 10 is moved with its surface 10F facing upwards, the protective cover (2a, 2b, 2c) may fall off due to its own weight. However, the protrusion 16 provided on the inner surface of the recess 15c of the blister 10 elastically holds the outer surface of the protective cover (2a, 2b, 2c). Specifically, the protrusion 16 presses against the outer surface of the protective cover (2a, 2b, 2c), generating friction. As a result, the blister 10 can hold the protective cover (2a, 2b, 2c).

[0057] Figure 4D shows the blister pack 10 with the protective cover 2 attached, with the release film removed from the protective cover (2a, 2b, 2c), placed on the camera section (92a, 92b, 92c). Figure 4D shows pressing the protective cover 2b on top of the blister pack 10 with a fingertip. When the blister pack 10 is pressed, it deforms so that the protrusions 16 on the inner surface that elastically hold the protective cover 2b spread outwards. As a result, the elastic hold of the protective cover 2b by the blister pack 10 is released, the holding force of the blister pack 10 disappears, and the pressed protective cover 2b comes into contact with the camera section 92b. Because the blister pack 10 (including the protrusions 16) made of flexible resin material bends with little force, when pressing the surface 10F of the blister pack 10 to release the elastic hold of the protective cover 2b, the elastic hold of the protective cover 2b can be released with a small pressing force. The protective covers (2a, 2c) should be pressed in the same way as protective cover 2b. The number of presses should be between 1 and 10 times for each protective cover (2a, 2b, 2c).

[0058] The protrusion 16 is an optional and not essential component. In other words, the blister 10 does not have to have the protrusion 16. For example, if the inner diameter of the recess 15 of the blister is substantially the same as or slightly smaller than the outer diameter of the protective cover 2, the inner surface of the recess 15 can exert a pressing force on the outer surface of the protective cover 2, generating friction, and as a result, the blister 10 can elastically hold the protective cover (2a, 2b, 2c).

[0059] When the protective covers (2a, 2b, 2c) come into contact with the camera section (92a, 92b, 92c), the adhesive on the protective covers (2a, 2b, 2c) comes into contact with the camera section (92a, 92b, 92c), and the protective covers (2a, 2b, 2c) are attached to the camera section (92a, 92b, 92c). Similarly, for the protective covers (2a, 2c), the blister 10 is held between the fingertips and the protective covers (2a, 2c) are pressed several times to attach them to the camera section (92a, 92c). Finally, the blister 10 is removed from the mobile terminal 90. When the blister 10 is removed, the protective covers (2a, 2b, 2c) already attached to the mobile terminal 90 are not removed along with the blister 10.

[0060] In this way, by simply placing the blister pack 10 containing the protective covers (2a, 2b, 2c) onto the camera section (92a, 92b, 92c) of the mobile device and pressing the blister pack 10 against the camera section (92a, 92b, 92c), the protective covers (2a, 2b, 2c) can be attached to the camera section (92a, 92b, 92c) without touching the protective covers (2a, 2b, 2c). This prevents oil and dirt from adhering to the protective covers (2a, 2b, 2c).

[0061] Furthermore, with conventional protective cover mounting methods that do not use the blister pack 10, when attaching multiple protective covers 2 to the camera unit 92, it is necessary to precisely align each protective cover 2 one by one. However, in this embodiment, by using the blister pack 10, three protective covers (2a, 2b, 2c) can be attached to three camera units (92a, 92b, 92c) simultaneously with a single alignment. In other words, because the three protective covers (2a, 2b, 2c) are aligned with each other within the blister pack 10, using the blister pack 10 has the further effect of reducing the number of alignments required.

[0062] <Second Embodiment> The second embodiment will be described with reference to Figures 5A to 5C. Note that the configuration common to the first embodiment will not be explained. All matters other than those described below can be implemented in the same manner as the first embodiment. The same applies to the third embodiment and subsequent embodiments.

[0063] Figure 5A shows a blister 50 that constitutes the components of the second embodiment. Figure 5B is a cross-sectional view of the blister 50 along the line X2-X2 in Figure 5A. Figure 5C is a diagram illustrating how to attach the protective cover 2 using the blister 50 in the second embodiment.

[0064] The structure has protective covers corresponding to N (N: a natural number from 1 to 5) camera units. In the first embodiment, an example of a blister 10 corresponding to three protective covers was described, but the blister 50 of the structure in the second embodiment corresponds to only one protective cover 2. Looking at Figure 5B, the back surface 50B of the blister 50 has a recess 15 in the center that accommodates a single protective cover 2. In Figure 5B, the two protrusions on either side of the protrusion 11 are convex guides 12.

[0065] As shown in Figure 5A, the blister 50 has a straight side edge 26 and a straight top edge 28. As shown in Figure 5C, when the blister 50 is placed over the camera portion 92 of the mobile terminal 90, the side edge 26 of the blister 50 overlaps with the side edge 96 of the mobile terminal 90, and the top edge 18 of the blister 50 overlaps with the top edge 98 of the mobile terminal 90. By overlapping the edge of the blister 50 with the edge of the mobile terminal 90 in this way, the protective cover 2, which is housed in the recess 15 of the blister 50 (see Figure 5B), is positioned relative to the camera portion 92 (see Figure 5C). Thus, even though the blister 50 corresponds to only a single protective cover 2, the blister 50 has an alignment function.

[0066] <Third Embodiment> A third embodiment will be described with reference to Figures 6A to 6D. Figure 6A is a diagram showing the blister 60. Figure 6B is a cross-sectional view taken along the line X3-X3 in Figure 6A. Figure 6C is a cross-sectional view taken along the line X4-X4 in Figure 6A. Figure 6D is a diagram showing the blister 60 being moved so that it is placed on top of the camera section (92a, 92b) with the surface 60F of the blister 60 facing the viewer.

[0067] Move the two protective covers (2a, 2b) above the camera section (92a, 92b, 92c) in the direction indicated by arrow A3 in Figure 6D. The mobile terminal 90 has two camera sections (92a, 92b). The two camera sections (92a, 92b) are located on a camera bump 91 that protrudes from the back of the mobile terminal 90. The two camera sections (92a, 92b) protrude further from the camera bump 91.

[0068] The blister 60 has a shape that fits the shape including the camera bump 91. More specifically, in Figure 6B, on the back surface 60B of the blister 60, the bump guide 17 is a recess arranged around the recess 15a that accommodates the protective cover 2a of the camera section 92a. The bump guide 17 has a shape that can accommodate the camera bump 91. On the front surface 60F of the blister 60, the bump guide 17 appears as a lower protrusion around the protrusion 11a corresponding to the recess 15a. By aligning the blister 60 with the mobile terminal 90 so that the bump guide 17 overlaps the camera bump 91 of the mobile terminal 90, the protective cover (2a, 2b) can be accurately aligned with the camera section (92a, 92b).

[0069] <Fourth Embodiment> A fourth embodiment will now be described. Figure 7A shows a protective cover 2 that protects the camera unit. Figures 7B and 7C show a mobile terminal 90 with the protective cover 2 attached. Unlike the first to third embodiments, the protective cover 2 of this embodiment can transition between a state in which the camera section (92a, 92b, 92c) is covered and protected when the camera section (92a, 92b, 92c) is not in use, and a state in which the camera section (92a, 92b, 92c) is not covered and is left open when the camera section (92a, 92b, 92c) is in use. The protective cover 2 of this embodiment has a cover body 2s, a mount 24, and a hinge 25 for opening and closing the cover body 2s relative to the mount 24. The protective cover 2 does not necessarily have to have a light-transmitting portion.

[0070] The mount 24 of this embodiment has through holes 19a to 19e. Through holes 19a, 19b, and 19c are openings for accommodating the camera unit 92 that protrudes from the mobile terminal 90. The cover body 2s is attached to the mobile terminal 90 when the mount 24 is fixed to the camera unit 92. Through holes 19d and 19e are openings for transmitting light from the flash mechanism (flash) of the mobile terminal 90, or detection openings for sensors, etc. When using the camera unit, flash mechanism, or sensor etc. located in the through holes 19a to 19e, the protective cover 2 is opened as shown in Figure 7B. When not using the camera unit, flash mechanism, or sensor etc. located in the through holes 19a to 19e, the protective cover 2 is closed as shown in Figure 7C.

[0071] Furthermore, as shown in Figure 7D, another use of the protective cover 2 is that when the cover body 2s of this embodiment is partially opened, the cover body 2s can be used as a stand for the mobile terminal 90, allowing the mobile terminal 90 to stand upright on the floor 99.

[0072] Figure 7E shows the blister 70 housing the protective cover 2 of this embodiment, viewed from the back surface 70B. The protective cover 2 is housed in the recess of the blister 70 with the mount 24 and cover body 2s closed. A projection 16 protruding from the inner surface of the blister 70 supports the protective cover 2 (the area hatched with diagonal lines in Figure 7E).

[0073] The various embodiments of the structure have been described above, with respect to modifications and variations as appropriate. The matters described herein are not limited to those described above and may include various modifications, substitutions, or additions that can be inferred by those skilled in the art. The matters described herein may also be combined as appropriate. Furthermore, a configuration for achieving a particular function may be replaced by other means having an equivalent function. The scope of this disclosure is defined solely by the claims and their equivalents and is not intended to be constrained by the description herein.

[0074] Although the camera unit 92 is described above as protruding from the back of the mobile terminal 90 or from the mount 24, the camera unit 92 does not have to protrude from the back of the mobile terminal 90 or from the mount 24. [Explanation of Symbols]
