Description

Technical Field

[0001] The present invention relates to a light-shielding box. More specifically, it relates to a light-shielding box that holds a camera for eye examination and can shield external light.

Background Art

[0002] Conventional eye examinations have generally been performed by arranging examination devices in a dark room and darkening the room. In particular, when photographing the fundus or the like with a photographing device such as a camera, in order to reduce the influence of external light, it is performed in a dark room where external light is shielded.

Summary of the Invention

Problems to be Solved by the Invention

[0003] When performing an eye examination, in order to shield external light and arrange an examination device such as a camera, it was necessary to secure a relatively large dark room. In addition, since it was difficult to perform the examination without a dark room, the places where the examination could be performed were limited.

[0004] Therefore, the light-shielding box according to the present invention aims to provide a light-shielding box that houses an examination camera and can shield external light.

Means for Solving the Problems

[0005] The light-shielding box according to the present invention is a light-shielding box that houses a mobile terminal with a camera, and includes a main body portion having a window portion, and a cover portion that covers the window portion of the main body portion. The main body portion has a cylindrical portion and an inclined portion connected to the front side of the cylindrical portion and having an inclined inner surface, and the window portion of the main body portion is formed on the surface portion of the inclined portion. When the cover portion is placed on the inclined portion side of the main body portion, a gap portion for housing the mobile terminal with a camera is formed between the main body portion and the cover portion, and it is possible to photograph the user's face through the window portion in a light-shielded state using the mobile terminal with a camera.

[0006] In the light-shielding box according to the present invention, the cover is placed over the main body from the inclined side, and a camera-equipped mobile device is stored between the main body and the cover, thus easily achieving a light-shielding state. Furthermore, when the cover is placed over the main body from the inclined side, a gap for storing the camera-equipped mobile device is formed between the main body and the cover, so the camera-equipped mobile device can be easily stored in this gap. In addition, since the main body has an inclined part connected to the front side of the cylindrical part and having an inclined side surface, the cover can be easily placed over the main body from the inclined side. As a result, the user's face can be easily photographed through the window provided in the main body while the light is shielded using the camera-equipped mobile device.

[0007] Furthermore, the light-shielding box according to the present invention may be characterized in that the side surface of the cover portion is inclined outward, and when the cover portion is placed over the main body portion, the outer surface of the main body portion comes into contact with the inclined side surface of the cover portion, so that the distance between the main body portion and the cover portion in the gap for housing the camera-equipped mobile terminal is approximately the same as the thickness of the camera-equipped mobile terminal.

[0008] In the light-shielding box according to the present invention, the side surface of the cover portion has an outwardly inclined side surface. As a result, when the cover portion is placed over the main body portion, the outer surface of the main body portion comes into contact with the inclined side surface of the cover portion, so that the distance between the main body portion and the cover portion in the gap formed between the main body portion and the cover portion is approximately the same as the thickness of the camera-equipped mobile terminal.

[0009] Furthermore, in the light-shielding box according to the present invention, a folded portion may be formed on the tip side of the surface portion of the main body. The inclined portion of the main body may have a notch that extends forward from the boundary between the cylindrical portion and the inclined portion. Also, on the side surface of the notch, the edge of the inclined portion is inclined toward the center in the height direction toward the front, and both edges on the surface portion side of the folded portion are inclined toward the rear and outward in the width direction to form a first stopper portion. Furthermore, the folded portion may be configured to be inserted into the lower surface of the side portion in the height direction of the inclined portion and covered with the surface portion, and the side portion in the width direction of the inclined portion may be configured to bend and deform until it contacts the first stopper portion of the folded portion that is inserted into the lower surface of the side portion in the height direction.

[0010] In the light-shielding box according to the present invention, the inclined portion of the main body may have a notch that extends forward from the boundary between the cylindrical portion and the inclined portion. This notch allows for the formation of a gap between the height-direction side portion and the width-direction side portion of the inclined portion for inserting a folding portion. When the cover portion is placed over the main body, the width-direction side portion of the inclined portion of the main body abuts against and is pressed against the side portion of the cover. At this time, the width-direction side portion of the inclined portion may have a structure that allows it to move inward. Furthermore, the width-direction side portion of the inclined portion is configured to bend and deform until it abuts against a first stopper portion formed in the folding portion inserted into the lower surface of the height-direction side portion. As a result, even when the width-direction side portion of the inclined portion is pressed against the side portion of the cover when the cover portion is placed over the main body, it has a structure that allows it to move inward, thus preventing the height-direction side portion of the inclined portion from bulging and deforming into a convex shape due to the pressure from the side portion of the cover, thereby preventing the formation of a gap. As a result, the light-shielding performance can be improved.

[0011] Furthermore, in the light-shielding box according to the present invention, the edge of the inclined portion constitutes a second stopper portion, and the side portion in the height direction of the inclined portion is configured to bend and deform until it contacts the second stopper portion. As a result, when the cover portion is placed over the main body portion, even when the side portion in the height direction of the inclined portion is pressed by the side of the cover portion, it has a structure that allows it to move inward until it contacts the second stopper portion, thereby preventing the side portion in the width direction of the inclined portion from bulging out and deforming into a convex shape, thus preventing the formation of a gap. As a result, the light-shielding performance can be improved.

[0012] Furthermore, the light-shielding box according to the present invention may be characterized in that the second stopper portion and the edge of the side portion in the height direction are in contact, or the first stopper portion, the second stopper portion, and the edge of the side portion in the height direction are in contact, filling the gap in the cut-out portion. As a result, when the cover portion is placed over the main body portion, the second stopper portion and the edge of the side portion in the height direction are in contact, or the first stopper portion, the second stopper portion, and the edge of the side portion in the height direction are in contact, filling the gap in the cut-out portion, thus further improving the light-shielding performance.

[0013] Furthermore, in the light-shielding box according to the present invention, the notched portion may be characterized by being formed by a V-shaped cut that opens forward along the boundary of the side portion of the inclined portion when unfolded. [Effects of the Invention]

[0014] In the light-shielding box according to the present invention, the cover is placed over the main body from the inclined side, and a camera-equipped mobile device is stored between the main body and the cover, thus easily achieving a light-shielding state. Furthermore, when the cover is placed over the main body from the inclined side, a gap for storing the camera-equipped mobile device is formed between the main body and the cover, so the camera-equipped mobile device can be easily stored in this gap. In addition, since the main body has an inclined part connected to the front side of the cylindrical part and having an inclined side surface, the cover can be easily placed over the main body from the inclined side. As a result, the user's face can be easily photographed through the window provided in the main body while the light is shielded using the camera-equipped mobile device.

Embodiments for Carrying out the Invention

[0016] The light-shielding box according to some embodiments will be described below with reference to the drawings. In the description of the drawings, the same reference numerals are assigned to the same elements, and duplicate descriptions are omitted. In the description, terms indicating directions such as "upper", "lower", "left", and "right" are for convenience based on the state shown in the drawings.

[0017] FIG. 1 schematically shows a perspective view of the light-shielding box 1 according to this embodiment. FIG. 2 schematically shows an assembly drawing of the light-shielding box 1. Also, FIG. 3 schematically shows a top view of the light-shielding box 1. The light-shielding box 1 according to this embodiment is used for photographing and inspecting the movement of the eyes of the subject. As shown in FIGS. 1 to 3, the light-shielding box 1 has a main body 2 and a cover part 3 that covers the main body 2, and a gap 4 for accommodating the mobile terminal 100 with a camera is formed between the main body 2 and the cover part 3. The mobile terminal 100 with a camera is installed in the gap 4, and the camera attached to this mobile terminal 100 is used to photograph the movement of the eyes of the subject for inspection.

[0018] When photographing the eye movements of a subject for examination, a camera-equipped portable terminal 100 can be placed in the gap 4 formed between the main body 2 and the cover 3 of the light-shielding box 1. The camera-equipped portable terminal 100 is positioned between the main body 2 and the cover 3, and when the cover 3 is placed over the main body 2, the camera-equipped portable terminal 100 is sandwiched between the main body 2 and the cover 3, thereby fixing and holding the camera-equipped portable terminal 100 in place.

[0019] Furthermore, the light-shielding box 1 has a light-shielding structure inside that prevents external light from entering, thereby reducing the influence of external light and enabling highly accurate eye examinations. The light-shielding structure will be explained in detail later.

[0020] The cover portion 3 of the light-shielding box 1 has a roughly rectangular box shape with an opening on its back side. The main body portion 2 also has a roughly rectangular box shape with an opening on its back side. The camera-equipped mobile terminal 100 is placed on the inner bottom surface of the cover portion 3 so that the camera portion of the camera-equipped mobile terminal 100 faces towards the opening side of the cover portion 3. The cover portion 3 can be placed over the main body portion 2 such that the back side of the cover portion 3 with the opening covers the front side of the main body portion 2 with the window portion 5. In this case, the cover portion 3 can cover the main body portion 2 by inserting each of the four inner surfaces of its sides along the corresponding outer surfaces of the four sides of the main body portion 2 up to a certain point.

[0021] Referring to Figures 2 and 3, a gap 4 is provided between the main body 2 and the cover 3 of the light-shielding box 1 for installing the camera-equipped mobile terminal 100. The camera-equipped mobile terminal 100 is installed between the main body 2 and the cover 3, on the bottom side of the cover 3. When the cover 3 is placed over the main body 2, the camera-equipped mobile terminal 100 is sandwiched between the main body 2 and the cover 3, thereby fixing and holding the camera-equipped mobile terminal 100 in place. Furthermore, by inserting the inner surface of the cover 3 along the outer surface of the main body 2 and covering the main body 2, the space (gap 4) between the main body 2 and the cover 3 for installing the camera-equipped mobile terminal 100 is shielded from light. This reduces the influence of ambient light when photographing the eye movements of a subject using the camera attached to the camera-equipped mobile terminal 100 for examination. As a result, it is possible to photograph and examine the eye movements of a subject using the camera attached to the camera-equipped mobile terminal 100 without being affected by ambient light.

[0022] Furthermore, the front surface 9 of the main body 2 has a window 5 with an opening for photographing the subject's eyeballs with the camera attached to the mobile terminal 100. On the back side of the main body, opposite the front surface, there is an opening 6 for the subject to look through. The upper and lower edges of the opening 6 on the back side of the main body 2 are formed with a curved shape (recessed shape) that is cut based on the contours of the forehead and nose of multiple subjects' faces. By providing the opening 6 with a curved shape that matches the contours of the subject's face, when the subject places their face against the opening 6 of the light-shielding box 1 and looks through the window 5 into the camera attached to the mobile terminal 100, the edges of the opening fit the subject's face, thus preventing outside light from entering.

[0023] Next, the main body 2 of the light-shielding box 1 will be described in detail. Figure 4 shows a plan view of the main body 2 of the light-shielding box 1 as seen from above. As shown in Figures 4 and 7, the main body 2 may include a cylindrical portion 7 and an inclined portion 8 connected to the cylindrical portion 7 and positioned on the front surface side of the main body 2. On the back side of the main body 2, opposite the front surface, there is an opening 6 for the user to look into, and a cut curved shape (recessed shape) is formed. Note that Figure 4 shows a reference line S1 extending in the direction of extension of the cylindrical portion 7.

[0024] The cylindrical portion 7 has a cylindrical shape, and its cross-sectional shape can be substantially rectangular. However, the shape of the cylindrical portion 7 is not limited to this, and its cross-section may be circular, elliptical, or polygonal.

[0025] Furthermore, the tip of the inclined portion 8 corresponds to the surface portion 9 of the main body portion 2, and a window portion 5 consisting of a through hole is formed on this surface portion 9 so that the eyeballs of the subject can be photographed using the camera attached to the camera-equipped mobile terminal 100. Also, as shown in Figure 4, the first side portion 12, second side portion 13, third side portion 14, and fourth side portion 15, which are the sides of the inclined portion 8, are inclined inward with respect to the reference line S1 as they move from the cylindrical portion 7 towards the surface portion 9 where the window portion 5 is provided, and the cross-sectional area can be made to gradually decrease. In this embodiment, each of the four side portions of the inclined portion 8 (first side portion 12, second side portion 13, third side portion 14, and fourth side portion 15) can have surfaces that are inclined at approximately the same angle. The inclined portion 8 has a structure in which, when viewed from the front side to the back side of the main body portion 2, the side surface of the inclined portion 8 is inclined outward, and the surface area of ​​the tip of the inclined portion 8 (or main body portion 2) is smaller than the cross-sectional area of ​​the cylindrical portion 7. Furthermore, the angle (inclination angle) θ1 formed by the extension direction of the side surface of the inclined portion 8 and the extension direction of the cylindrical portion 7 (extension direction of the reference line S1) can be, for example, in the range of 5 degrees or more and 15 degrees or less. In this embodiment, the angle θ1 formed by the extension direction of the side surface of the inclined portion 8 and the extension direction of the cylindrical portion 7 can be about 10 degrees.

[0026] The surface portion 9 of the main body portion 2, which is provided with a window portion 5, can be made into a box shape by inserting the folding portion 10 (see Figure 7), which is connected to the upper part of this surface, into the lower side (back side) of the third side portion 14 on the upper side (height direction) of the main body portion 2. The folding portion 10 is not fixed to the upper side with adhesive or the like, and can be freely inserted and removed from the front and back. Furthermore, the structure allows for assembly and disassembly by inserting and removing the folding portion 10 into the inside of the upper side.

[0027] In the light-shielding box 1, the side portions of the inclined portion 8 (first side portion 12, second side portion 13, third side portion 14, and fourth side portion 15) are formed to bend and deform using the fold lines for bending as pivot points. When the cover portion 3 is placed over the main body portion 2, the inner surface of the cover portion 3 abuts against the outer surface of the main body portion 2, and when the outer surface of the main body portion 2 is pressed, the outer surface of the inclined portion 8 moves in the direction of the pressure. This prevents the side portions of the inclined portion from becoming distorted or curved and forming gaps due to the pressure. In other words, even when the outer surface of the main body portion 2 is pressed, it is difficult for gaps to form in the side portions of the inclined portion, so that external light does not enter through the gaps and reduce the light-shielding performance, which can be effectively avoided.

[0028] Next, the cover portion 3 of the light-shielding box 1 will be described in detail. Figure 5 shows a schematic perspective view of the cover portion 3 of the light-shielding box 1. Figure 6 shows a schematic cross-sectional view taken along the line VI-VI in Figure 5. In Figure 6, a reference line S2 is shown extending perpendicularly to the bottom surface of the cover portion 3.

[0029] As shown in Figure 5, the cover portion 3 has a box-like shape with an opening at the top (back side) in the cover portion 3 shown in Figure 5, corresponding to the shape of the main body portion 2, and its cross-sectional shape can be approximately rectangular. In addition, the cover portion 3 can have a circular, elliptical, or polygonal cross-section, corresponding to the shape of the main body portion 2.

[0030] Furthermore, the cover portion 3 has a bottom on the front side, and an opening on the back side facing the front. By placing the cover portion 3 over the main body portion 2 from the front side to the back side, with the opening of the cover portion 3 facing the front side of the main body portion 2, the sides and front of the main body portion 2 can be covered with the cover portion 3.

[0031] Furthermore, as shown in Figure 6, the sides of the cover portion 3 are inclined outward when viewed from the front side towards the back side. In other words, the cover portion 3 can have a structure in which the sides are inclined so that the cross-sectional area of ​​the cover portion 3 gradually increases from the bottom, which is the front side, towards the back side. The cover portion 3 can also be assembled by folding inward the flaps (fifth cover flap 42e and sixth cover flap 42f) that are connected to the opposing sides of the cover portion 3 (third cover side 41c and fourth cover side 41d). The method of assembling the cover portion 3 will be described in detail later. The angle θ2 (angle of inclination) between the extension direction of the side of the cover portion 3 and the reference line S2 can be, for example, in the range of 5 degrees to 20 degrees. In this embodiment, the angle θ2 (angle of inclination) between the extension direction of the side of the cover portion 3 and the reference line S2 can be about 11 degrees. The angle θ2 (angle of inclination) between the extension direction of the side surface of the cover portion 3 and the reference line S2 determines the insertion depth of the main body portion 2 into the cover portion 3 when the cover portion 3 is placed over the main body portion 2. The side surface of the cover portion 3 has a fixed structure by folding inward the flaps (fifth cover flap 42e and sixth cover flap 42f) that are connected to the opposing sides of the cover portion 3 (third cover side surface 41c and fourth cover side surface 41d), respectively. When the cover portion 3 is placed over the main body portion 2, even if the inner surface of the cover portion 3 comes into contact with the outer surface of the main body portion, the cover portion 3 hardly deforms, so the angle of inclination of the side surface of the cover portion 3 is kept constant. As a result, when the cover portion 3 is placed over the main body portion 2, the insertion depth of the main body portion 2 into the cover portion 3 is kept constant, corresponding to the inclination angle of the cover. When the angle θ2 (inclination angle) between the extending direction of the side surface of the cover portion 3 and the reference line S2 is approximately 11 degrees, the insertion depth of the main body portion 2 into the cover portion 3 when the cover portion 3 is placed over the main body portion 2 can be set to approximately 10 mm. This ensures that a gap 4 is secured between the surface of the main body portion 2 and the bottom of the cover portion 3 for positioning and holding the mobile device. Furthermore, the angle θ2 (inclination angle) between the extending direction of the side surface of the cover portion 3 and the reference line S2 can be designed to correspond to the thickness of the mobile device being used.

[0032] In this embodiment, the main body 2 and the cover 3 can each be assembled by folding a single sheet of flat paper material. Figures 7 and 8 show the unfolded view of the main body 2 before assembly. Figure 9 also shows the unfolded view of the cover 3 before assembly.

[0033] Next, the unfolded view of the main body 2 will be explained in detail using Figure 7. As shown in Figure 7, the main body 2 can have a surface portion 9 with a window portion 5. A folded portion 10 is connected to the upper side of the surface portion 9. A first side portion 12 is connected to the lower side of the surface portion 9, opposite to the upper side to which the folded portion 10 is connected (the lower side). Also, in Figure 6, a second side portion 13 is connected to the lateral (right) side of the first side portion 12. Similarly, a third side is connected to the lateral (right) side of the second side portion 13. Furthermore, a fourth side is connected to the lateral (right) side of the third side portion 14. In other words, the second side portion 13, the third side, and the fourth side are continuously connected to the lateral (right) side of the first side portion 12. Furthermore, an adhesive portion 16 is connected to the side of the first side portion opposite to the side to which the second side portion is connected, for gluing and fixing it to the fourth side portion when assembled.

[0034] Furthermore, the first flap 17 and the second flap 18 are connected to the upper and lower edges of the second side portion 13, respectively. Also, the third flap 19 and the fourth flap 20 are connected to the upper and lower edges of the fourth side portion 15, respectively. The first flap 17 and the third flap 19 are provided to support the surface so that it does not extend too far inside the main body portion 3 when the main body portion 3 is assembled, by being folded inward. On the other hand, the second flap 18 and the fourth flap 20 are folded inward when the main body portion 2 is assembled to form the back surface 9. The back surface 9 is formed so as to be partially covered by the second flap 18 and the fourth flap 20, thereby creating an opening 6 for the subject to look through.

[0035] Furthermore, a first insertion portion 21 and a second insertion portion 22 are formed on the mutually opposing sides of the second flap 18 and the fourth flap 20. The first insertion portion 21 and the second insertion portion 22 are formed on each of the second flap 18 and the fourth flap 20. When assembling the main body portion 2 of the light-shielding box 1, the first insertion portion 21 and the second insertion portion 22 can be inserted into the first insertion hole 23 and the second insertion hole 24 formed at corresponding positions on the third side surface to fix the second flap 18 and the fourth flap 20 to the third side surface.

[0036] Furthermore, a first fold line 25a extending in the vertical direction is formed at the boundary where the first side portion 12 and the second side portion 13 are connected. A second fold line 25b extending in the vertical direction is formed at the boundary where the second side portion 13 and the third side portion 14 are connected. A third fold line 25c extending in the vertical direction is formed at the boundary where the third side portion 14 and the fourth side portion 15 are connected. Furthermore, a fourth fold line 25d extending in the vertical direction is formed at the boundary where the fourth side portion 15 and the adhesive portion 16 are connected.

[0037] Furthermore, a fifth fold line 25e extending to the left and right is formed at the boundary where the second side portion 13 and the first flap 17 are connected. A sixth fold line 25f extending to the left and right is formed at the boundary where the second side portion 13 and the second flap 18 are connected. A seventh fold line 25g extending to the left and right is formed at the boundary where the fourth side portion 15 and the first flap 19 are connected. An eighth fold line 25h extending to the left and right is formed at the boundary where the fourth side portion 15 and the second flap 20 are connected. A ninth fold line 25i extending to the left and right is formed at the boundary where the first side portion 12 and the surface portion 9 are connected. Furthermore, a tenth fold line 25j extending to the left and right is formed at the boundary where the surface portion 9 and the folded portion 10 are connected. In this embodiment, perforations are further formed on the first fold line 25a and the third fold line 25c. By forming perforations along the first fold line 25a and the third fold line 25c, a structure that is easy to fold can be created at the positions of the first fold line 25a and the third fold line 25c.

[0038] A V-shaped notch 11 is formed at one end (the upper end in Figure 6) of each of the first fold line 25a, second fold line 25b, third fold line 25c, and fourth fold line 25d. Referring to Figure 6, a first notch 11a is formed at one end of the first fold line 25a. A second notch 11b is formed at one end of the second fold line 25b. A third notch 11c is formed at one end of the third fold line 25c. A fourth notch 11d is formed at one end of the fourth fold line 25d.

[0039] Figure 8 shows an enlarged view of section A, which has a second notch 11b, as an example of the V-shaped notch 11 in Figure 7. A reference line S3 is shown in Figure 8. Other notches 11 (first notch 11a, third notch 11c, fourth notch 11d) can also have a similar structure. As shown in Figure 8, in the notch 11 (second notch 11b), the side of the second side portion 13 has a first inclined side 32a that is cut diagonally with respect to the reference line S3. The side of the third side portion 14 opposite the first inclined side 32a has a second inclined side 32b that is cut diagonally with respect to the reference line S3. In this embodiment, the angle θ3a between the first inclined side 32a and the reference line S3 and the angle θ3b between the second inclined side 32b and the reference line S3 are set to approximately the same value (θ3). The angles θ3a and θ3b are preferably between 5 and 15 degrees. Also, in Figure 8, the length lv of the notched portion 11 (the distance between the fifth fold line 25e, the seventh fold line 25g, and the ninth fold line 25i extending to the left and right, and the vertex of the V shape) is preferably about 12 to 20 mm. In this embodiment, the angles θ3a and θ3b are each set to about 10°. The length lv of the notched portion 11 is set to about 15 mm. In this embodiment, the upper edge of the third side portion 14 is designed to be higher than the fifth fold line 25e by a distance equivalent to the thickness of the folded portion 10 (about 2 mm). In other words, the distance from the sixth fold line 25f of the third side portion 14 to the upper edge is set to be slightly greater than the distance from the sixth fold line 25f of the second side portion 13 to the fifth fold line 25e. As a result, when the main body 3 is assembled, the folding portion 10 is guided by the protruding upper edge of the third side portion 14, making it easier to insert into the lower side of the third side portion 14.

[0040] By forming V-shaped notches 11 (first notch 11a, second notch 11b, third notch 11c, and fourth notch 11d) at one end (upper end side in Figure 7) of each of the first fold line 25a, second fold line 25b, third fold line 25c, and fourth fold line 25d, when the main body 2 is assembled, an inclined portion 8 connected to the cylindrical portion 7 of the main body 2 can be formed, as shown in Figure 4. Furthermore, the angle θ1 of the side surface of the inclined portion 8 can be defined by the angle θ3a made between the first inclined side 32a and the reference line S3, and the angle θ3b made between the second inclined side 32b and the reference line S3.

[0041] Furthermore, referring to Figure 7, the lower edge of the first side portion 12 opposite to the ninth fold line 25i has a shape that resembles the shape of a nose. Also, the lower edge of the third side portion 14 has a shape that resembles the shape of a forehead.

[0042] Furthermore, as shown in Figure 7, the left and right sides of the folding portion 10 can be angled outward and slightly protruding outward. This makes it easier to insert the folding portion 10 into the lower side of the third side portion 14 when the main body portion 2 is assembled, by angling the sides of the folding portion 10 outward and slightly protruding outward.

[0043] Next, the unfolded view of the cover part 3a of the cover section 3 will be described in detail using Figure 9. Note that a reference line S4 is shown in Figure 9. As shown in Figure 9, the cover section 3 may have a roughly rectangular cover bottom surface 40 and four cover sides 40 (first cover side 41a, second cover side 41b, third cover side 41c, and fourth cover side 41d) connected to each of the four sides of the cover bottom surface 40. Furthermore, the first cover flap 42a and the second cover flap 42b are connected to both the left and right ends of the first cover side 41a, which is connected to the upper edge of the cover bottom surface 40. Similarly, the third cover flap 42c and the fourth cover flap 42d are connected to both the left and right ends of the second cover side 41b, which is positioned below and opposite the first cover side 41a. Additionally, the fifth cover flap 42e is connected to the left end of the third cover side 41c, which is connected to the left edge of the cover bottom surface 40. Similarly, the sixth cover flap 42f is connected to the right end of the fourth cover side 41d, which is located to the right of the third cover side 41c.

[0044] Furthermore, a first cover fold line 43a extending left and right is formed at the boundary between the cover bottom surface 40 and the first cover side surface 41a connected to the upper edge of the cover bottom surface 40. A second cover fold line 43b extending left and right is formed at the boundary between the cover bottom surface 40 and the second cover side surface 41b connected to the lower edge of the cover bottom surface 40. Furthermore, a third cover fold line 43c extending up and down is formed at the boundary between the cover bottom surface 40 and the third cover side surface 41c connected to the left edge of the cover bottom surface 40. Furthermore, a fourth cover fold line 43d extending left and right is formed at the boundary between the cover bottom surface 40 and the fourth cover side surface 41d connected to the right edge of the cover bottom surface 40.

[0045] Furthermore, at the boundary between the first cover side surface 41a and the first cover flap 42a and the second cover flap 42b, which are connected to the left and right ends of the first cover side surface 41a, a fifth cover fold line 43e and a sixth cover fold line 43f are formed, extending vertically, respectively. Referring to Figure 9, the fifth cover fold line 43e is inclined to spread outwards upward. Similarly, the sixth cover fold line 43f is also inclined to spread outwards upward. In Figure 9, it is shown that the sixth cover fold line 43f is inclined to spread outwards by an angle θ4 with respect to the reference line S4. Likewise, at the boundary between the second cover side surface 41b and the third cover flap 42c and the fourth cover flap 42d, which are connected to the left and right ends of the second cover side surface 41b, a seventh cover fold line 43g and an eighth cover fold line 43h are formed, extending vertically, respectively. The seventh cover fold line 43g is sloped upwards and outwards. Similarly, the eighth cover fold line 43h is also sloped upwards and outwards.

[0046] When assembling the cover section 3, the first cover side 41a is folded inward along the first cover fold line 43a, and the first cover flap 42a and the second cover flap 42b are folded along the fifth cover fold line 43e and the sixth cover fold line 43f. Similarly, the second cover side 41b is folded inward along the second cover fold line 43b, and the third cover flap 42c and the fourth cover flap 42d are folded along the seventh cover fold line 43g and the eighth cover fold line 43h. In this case, since the left and right ends of the first cover side surface 41a are defined by the fifth cover fold line 43e and the sixth cover fold line 43f, as shown in Figure 6, each side of the third cover side surface 41c and the fourth cover side surface 41d that abut the left and right ends of the first cover side surface 41a of the cover portion 3 can be inclined outward in accordance with the inclination angle θ4 of the fifth cover fold line 43e and the sixth cover fold line 43f.

[0047] Furthermore, the length of the top of the fifth cover flap 42e is set to be greater than the length of the third cover fold line 43c on the cover bottom surface 40. Similarly, the length of the top of the sixth cover flap 42f is set to be greater than the length of the fourth cover fold line 43d on the cover bottom surface 40. When assembling the cover, the third cover side surface 41c is folded inward along the third cover fold line 43c, and the fifth cover flap 42e, which is connected to the third cover side surface 41c, is further folded inward along the ninth cover fold line 43i. At this time, the tip of the fifth cover flap 42e is located near the cover bottom surface 40, and both ends of the tip of the fifth cover flap 42e abut against the first cover side surface 41a and the second cover side surface 41b.

[0048] Furthermore, the fourth cover side 41d is folded inward along the fourth cover fold line 43d, and the sixth cover flap 42f connected to the fourth cover side 41d is further folded inward along the tenth cover fold line 43j. At this time, the tip of the sixth cover flap 42f is located near the bottom surface 40 of the cover, and both ends of the tip of the sixth cover flap 42f abut against the first cover side 41a and the second cover side 41b.

[0049] Since the length of the top of the fifth cover flap 42e is set to be greater than the length of the third cover fold line 43c of the cover bottom surface 40, when the tip of the fifth cover flap 42e is located near the cover bottom surface 40 and both ends of the tip of the fifth cover flap 42e come into contact with the first cover side surface 41a and the second cover side surface 41b, the first cover side surface 41a and the second cover side surface 41b are pushed outward, causing them to tilt outward as shown in Figure 5.

[0050] Similarly, since the length of the top of the sixth cover flap 42f is set to be greater than the length of the fourth cover fold line 43d of the cover bottom surface 40, when the tip of the sixth cover flap 42f is located near the cover bottom surface 40 and both ends of the tip of the sixth cover flap 42f come into contact with the first cover side surface 41a and the second cover side surface 41b, the first cover side surface 41a and the second cover side surface 41b are pushed outward, causing them to tilt outward as shown in Figure 5. As a result, each of the first cover side surface 41a, the second cover side surface 41b, the third cover side surface 41c, and the fourth cover side surface 41d can have an outwardly tilted surface as shown in Figure 6.

[0051] Furthermore, when the fifth cover flap 42e, connected to the third cover side 41c, is folded inward along the ninth cover fold line 43i, the already folded first cover flap 42a and third cover flap 42c are sandwiched inside as the flap is folded, thereby supporting the first cover side 41a and second cover side 41b. Also, when the sixth cover flap 42f, connected to the fourth cover side 41d, is folded inward along the tenth cover fold line 43j, the already folded second cover flap 42b and fourth cover flap 42d are sandwiched inside as the flap is folded, thereby supporting the first cover side 41a and second cover side 41b. Furthermore, both ends of the tip of the fifth cover flap 42e abut against the first cover side 41a and the second cover side 41b, pushing the first cover side 41a and the second cover side 41b outward, thereby supporting and fixing the fifth cover flap 42e to the first cover side 41a and the second cover side 41b. Similarly, both ends of the tip of the sixth cover flap 42f abut against the first cover side 41a and the second cover side 41b, pushing the first cover side 41a and the second cover side 41b outward, thereby supporting and fixing the sixth cover flap 42f to the first cover side 41a and the second cover side 41b. As a result, the cover portion 3 can be assembled without using adhesive or the like. Also, because no adhesive is used, the cover can be easily unfolded and assembled.

[0052] Next, the assembly method of the light-shielding box 1 will be explained in detail. Figure 10 shows a diagram illustrating the assembled state of the main body 2. Referring to Figure 10, the assembly method of the main body 2 will be explained first. The adhesive part 16 is glued to the back surface of the fourth side part 15 of the main body part 2a of the main body part 2 shown in Figure 7 (unfolded view of the main body), to form a cylindrical shape. The main body part 2a is designed to be folded along the first fold line 25a and the third fold line 25c, which have perforations, for storage or transport. By folding the main body part 2a into a flat state, it can be easily stored or transported.

[0053] When using the light-shielding box 1, the first side portion 12 and the second side portion 13 are folded along the first fold line 25a. Similarly, the second side portion 13 and the third side portion 14 are folded along the second fold line 25b. The third side portion 14 is folded along the third fold line 25c. This creates a cylindrical shape consisting of the first side portion 12, the second side portion 13, the third side portion 14, and the fourth side portion 15. Next, the first insertion portion 21 and the second insertion portion 22 are inserted into the first insertion hole 23 and the second insertion hole 24 formed at corresponding positions on the third side, thereby fixing the second flap 18 and the fourth flap 20 to the third side and maintaining the cylindrical shape.

[0054] Next, as shown in Figure 10, the first flap 17 and the third flap 19 are folded inward almost horizontally, and with the surface portion 9 folded so that it rests on the surfaces of the first flap 17 and the third flap 19. Referring to Figure 10, the first notch 11a is visible at one end of the first fold line 25a. The second notch 11b is visible at one end of the second fold line 25b. The third notch 11c is visible at one end of the third fold line 25c. Although not shown in Figure 10, the fourth notch 11d is formed at one end of the fourth fold line 25d. In addition, gaps are formed in the second notch 11b and the third notch 11c for inserting the folded portion 10.

[0055] Next, the folding portion 10 is inserted into the gaps formed in the second notch 11b and the third notch 11c. Figure 11 shows the state in which the folding portion 10 has been inserted into the gaps formed in the second notch 11b and the third notch 11c. Figure 11(a) shows the state in which the folding portion of the main body has been inserted into the notch, and Figure 11(b) shows the state in which the folding portion has been further inserted into the notch from the state in Figure 11(a). Referring to Figure 11, the insertion portion 10 is inserted below the third side portion 14 until the back side of the surface portion 9 contacts the surface of the third flap 19. At the second notch 11b, when the second side portion 13 is pressed inward, it is configured to bend and deform inward in response to the pressure. In addition, both ends of the folding portion 10 are inclined outward in the width direction toward the rear, forming the first stopper portion 45 (see Figures 10 and 11). The second side portion 13 is capable of bending and deforming until it contacts the first stopper portion 45. This allows the second side portion 13 to bend and deform, thereby relieving stress when stress is applied to the side of the main body portion 2, for example, when the cover portion 3 is placed over it, and preventing deformation such as the third side portion 14, sandwiched between the second side portion 13 and the fourth side portion 15, bulging outwards. Similarly, at the third notch portion 11c, the fourth side portion 15 is configured to bend and deform inwards in response to inward pressure. This allows the fourth side portion 15 to bend and deform, thereby relieving stress when stress is applied when the cover portion 3 is placed over it, and preventing deformation such as the third side portion 14, sandwiched between the second side portion 13 and the fourth side portion 15, bulging outwards.

[0055] Furthermore, in the second notch 11b and the third notch 11c, the third side portion 14 is configured to bend and deform inward in response to inward pressure. Also, as shown in Figures 10 and 11, the edge of the inclined portion 8 constitutes the second stopper portion 47. The third side portion 14 is capable of bending and deforming until it contacts this second stopper portion 47. As a result, for example, even if stress is applied to the side surface of the main body portion 2 when the cover portion 3 is placed over it, the third side portion 14 can bend and deform to relieve this stress, thereby suppressing deformation such as the second side portion 13 and / or the fourth side portion 15 bulging outwards.

[0056] Next, the assembly method for the cover part 3 will be explained. Fold the first cover side 41a of the cover part 3a of the cover part 3 shown in Figure 9 (unfolded view of the cover) inward along the first cover fold line 43a. Similarly, fold the second cover side 41b inward along the second cover fold line 43b. Next, fold the first cover flaps 42a and 2 cover flaps 42b, which are connected to both ends of the first cover side 41a, inward along the fifth cover fold line 43e and 6th cover fold line 43f, respectively. Similarly, fold the third cover flaps 42c and 4th cover flaps 42d, which are connected to both ends of the second cover side 40b, inward along the seventh cover fold line 43g and 8th cover fold line 43h, respectively. Next, the third cover side 41c can be folded along the third cover fold line 43c, and the fifth cover flap 42e connected to the third cover side 41c can be folded inward along the ninth cover fold line 43i, and pressed against the inner surfaces of the first cover side 41a and the second cover side 41b to secure them. At this time, the first cover flap 41a and the second cover side 41b can be supported by sandwiching the already folded first cover flap 42a and the third cover flap 42c inward and folding them. Similarly, the fourth cover side 41d can be folded along the fourth cover fold line 43d, and the sixth cover flap 42f connected to the fourth cover side 41d can be folded inward along the tenth cover fold line 43j, and pressed against the inner surfaces of the first cover side 41a and the second cover side 41b to secure them. At this time, the first cover side 41a and the second cover side 41b can be supported by folding the already folded second cover flap 42b and fourth cover flap 42d inwards.

[0057] In this embodiment, the inclination angle of the first cover side 41a and the second cover side 41b can be defined by pressing and fixing the fifth cover flap 42e against the inner surfaces of the first cover side 41a and the second cover side 41b. Similarly, the inclination angle of the first cover side 41a and the second cover side 41b can be defined by pressing and fixing the sixth cover flap 42f against the inner surfaces of the first cover side 41a and the second cover side 41b. In this embodiment, the angle of the first cover side 41a and the second cover side 41b with respect to the cover bottom surface 40 is set to approximately 92 to 98 degrees.

[0058] Next, the method of using the light-shielding box 1 will be explained in detail. The light-shielding box 1 is supplied in a folded state. Assemble the folded light-shielding box 1 as described above, and place the camera-equipped portable terminal 100 in the gap 4 between the main body 2 and the cover 3. Next, as shown in Figure 14, the subject looks through the opening 6 of the light-shielding box 1 using the camera attached to the camera-equipped portable terminal 100, and the camera attached to the portable terminal 100 can be used to photograph the subject's eye movements, etc. The captured image information can be output from the portable terminal 100 to an external image processing device, and the image information input to the image processing device can be used to examine the subject's eyeballs.

[0059] The light-shielding box 1 of this embodiment can be easily assembled and disassembled anywhere. Furthermore, since it is supplied in a folded state, it is easy to transport and store. Moreover, because it can easily create a darkroom environment, it is possible to photograph the eye movements of a subject without being affected by sunlight, under the same conditions as if photographing in a darkroom.

[0060] Next, a box body prepared as a comparative example will be described. Figure 12 shows a diagram illustrating the assembled state of the comparative example box body 200. The box body 200 can be assembled by first assembling the sides into a cylindrical shape, and then inserting the folded portion 210, which is connected to the tip side of the surface portion 209, into the insertion holes 220 (220a, 220b) formed between the flaps 217 and 219 and the upper side portion 214.

[0061] Figure 13 also shows a diagram illustrating the assembled state of the comparative example box 200. Figure 12(a) shows the state when no external pressure is applied to the side. Figure 12(b) shows the state when external pressure is applied to the opposing side. In the box 200, when the folded portion 210 is inserted into the insertion hole 220 (220a, 220b), a gap may occur between the folded portion 210 and the insertion hole 220 (220a, 220b), making it difficult to completely seal and form a darkroom. Also, as shown in Figure 13(b), when the side of the box 200 is pressed, the side of the box 200 (upper side 214 in Figure 13) bulges, creating a gap between the folded portion 210 and the side (upper side 214), from which external light may leak.

[0062] While the principles of the present invention have been illustrated and described in preferred embodiments, it will be recognized by those skilled in the art that the present invention can be modified in arrangement and detail without departing from such principles. The present invention is not limited to the specific configurations disclosed in these embodiments. Accordingly, all modifications and changes arising from the scope of the claims and their spirit are claimed. [Explanation of Symbols]
