[0025] According to one embodiment, electronic devices that perform various functions, such as smartphones, smart pads, and tablet PCs, can be made thin and light for portable purposes. Electronic devices may be vulnerable to external physical impacts. For example, when the electronic device is used alone without a case (100) that protects the electronic device, the external impact may cause damage, such as scratches, to the exterior of the electronic device or damage to the display. In addition, when the external impact is transferred to the interior of the electronic device, damage may occur to high-performance integrated circuits (e.g., printed circuit boards), sensors (e.g., cameras, speakers), etc. that constitute the electronic device. Therefore, when using an electronic device, a consumer may inevitably use a case (100) that protects the exterior of the electronic device from external impacts.

[0026] According to one embodiment, as illustrated in FIGS. 1A and 1B, a case (100) for protecting an electronic device may include a first cover (110), a second cover (120), and a connecting member (130) that rotatably connects the first cover (110) and the second cover (120). In one embodiment, the case (100) may be operated in an in-folding manner and / or an out-folding manner within a range of 0 degrees to 360 degrees via the connecting member (130). Hereinafter, a state in which an angle (θ) between the first cover (110) and the second cover (120) (e.g., an angle (θ) between the first cover (110) and the second cover (120) illustrated in FIG. 2A) is substantially 0 degrees will be described as a 'closed state', and a state in which a predetermined angle (θ) is formed between the first cover and the second cover (120) will be described as an 'open state' of the case (100). For example, the case (100) illustrated in FIGS. 1A and 1B can be described as a 'closed state', and the case (100) illustrated in FIG. 2A can be described as an 'open state'.

One side of the second cover (120) that comes into contact with the side surface of the electronic device located in the accommodation portion (123) of the second cover (120) may be formed of a material having a soft texture, such as natural / artificial leather or natural / synthetic fiber, similar to the third side (121). In one embodiment, the fourth side (122) of the second cover (120) may be a bumper layer that absorbs external impact. The bumper layer may be composed of the aforementioned PC, TPU, TPE, and / or silicone, and may also be composed of rubber or urethane. As described later, the fourth surface (122) of the second cover (120) is a surface that comes into contact with an object (e.g., the object (200) of FIG. 2a and / or the object (300) of FIG. 3c), and thus may be formed of a material having a higher surface roughness than the third surface (121).

[0033] According to one embodiment, a plurality of mounting grooves (141, 142) in which an object (200) can be positioned may be formed on at least one of the second surface (112) of the first cover (110) and the fourth surface (122) of the second cover (120). According to one embodiment, the object (200) may be a pen input device (e.g., a stylus pen) that is communicatively paired with an electronic device and capable of inputting (e.g., touching, drawing) to the electronic device. In one embodiment, the object (200) may include a magnetic body (M0) disposed therein. In one embodiment, the magnetic body (M0) may be a magnet, a metal object having magnetism (e.g., a plate).

[0034] In one embodiment, the mounting grooves (141, 142) (e.g., mounting groove (240) of FIG. 3a and / or mounting groove (340) of FIG. 3c) may be engraved grooves formed on at least one of the second surface (112) of the first cover (110) and the fourth surface (122) of the second cover (120). Referring to FIG. 1b in one embodiment, the mounting grooves (141, 142) may be formed on the second surface (112) of the first cover (110) and the fourth surface (122) of the second cover (120). In one embodiment, referring to FIGS. 3a to 3d described below, the mounting grooves (240, 340) may be formed on the fourth surface (122) of the second cover (120). In one embodiment, the anchoring groove (240, 340) may be formed only on the second side (112) of the first cover (110).

[0035] According to one embodiment, as illustrated in FIGS. 1A and 1B, a plurality of first mounting grooves (141) may be formed on the second surface (112) of the first cover (110). In one embodiment, the plurality of first mounting grooves (141) may be arranged at predetermined intervals along the X-axis of FIG. 1B. In one embodiment, the plurality of first mounting grooves (141) may be portions corresponding to valleys among a pattern of repetitive valleys and peaks formed on the second surface (112) of the first cover (110). In one embodiment, when the second surface (112) of the first cover (110) is a bumper layer, the second mounting grooves (142) may be formed in the bumper layer. In one embodiment, a part of the object (200) may be positioned in the first mounting groove (141).

[0036] In one embodiment, the first mounting groove (141) may be formed in a shape corresponding to the appearance of the object (200). In one embodiment, as illustrated in FIG. 2A, when the object (200) is circular, the first mounting groove (141) may be formed in a circular shape. In one embodiment, as illustrated in FIG. 3C, when the object (300) is an n-gon (n: a natural number greater than or equal to 3), the shape of the first mounting groove (141) may be formed in an n-gon corresponding to the object (300).

[0037] According to one embodiment, as illustrated in FIGS. 1A and 1B, a plurality of second mounting grooves (142) may be formed on the fourth surface (122) of the second cover (120). In one embodiment, the plurality of second mounting grooves (142) may be arranged at predetermined intervals along the X-axis of FIG. 1B. In one embodiment, the plurality of second mounting grooves (142) may be portions corresponding to valleys among a pattern of repetitive valleys and peaks formed on the fourth surface (122) of the second cover (120). In one embodiment, when the fourth surface (122) of the second cover (120) is a bumper layer, the second mounting grooves (142) may be formed in the bumper layer. In one embodiment, another part of an accessory may be positioned in the first mounting groove (141). For example, the object (200) can be placed in the first mounting groove (141) and the second mounting groove (142) while the case (100) is open so that the second side (112) of the first cover (110) and the fourth side (122) of the second cover (120) face each other. In this case, the parts of the object (200) placed in the first mounting groove (141) and the second mounting groove (142) can be different parts.

[0038] In one embodiment, the second mounting groove (142) may be formed in a shape corresponding to the appearance of the object (200). In one embodiment, as illustrated in FIG. 2A, when the object (200) is circular, the second mounting groove (142) may be formed in a circular shape. In one embodiment, as illustrated in FIG. 3D, when the object (300) is n-gonal (n: a natural number greater than or equal to 3), the shape of the second mounting groove (142) may be formed in an n-gonal shape corresponding to the object (300).

[0039] According to one embodiment, the plurality of first mounting grooves (141) and the plurality of second mounting grooves (142) may correspond to each other. For example, referring to FIG. 1B, when the case (100) is closed, the plurality of first mounting grooves (141) and the plurality of second mounting grooves (142) may be formed at positions corresponding to each other in the Z-axis direction. When the case (100) is closed, the corresponding first mounting grooves (141) and second mounting grooves (142) may correspond to each other even when the case (100) is rotated 360 degrees and opened so that the second surface (112) of the first cover (110) and the fourth surface (122) of the second cover (120) face each other. As described below, the object (200) may be placed in the corresponding first mounting grooves (141) and second mounting grooves (142).

[0040] According to one embodiment, when a user watches a video through an electronic device, if a configuration for standing the electronic device does not exist separately in the case (100), the user may experience inconvenience in having to hold the electronic device. According to one embodiment of the present disclosure, the case (100) can be stood at various angles when the first cover (110) and the second cover (120) form a predetermined angle (θ) in an open state. For example, the first cover (110) and the second cover (120) can form a predetermined angle (θ) in a state where the second surface (112) of the first cover (110) and the fourth surface (122) of the second cover (120) face each other. When the second surface (112) of the first cover (110) and the fourth surface (122) of the second cover (120) face each other, the angle (θ) formed by the first cover (110) and the second cover (120) can be fixed by an object (200) placed between the first cover (110) and the second cover (120). Accordingly, the case (100) can be stood on any surface by the first cover (110) and the second cover (120). A detailed description thereof will be provided below.

[0041] According to one embodiment, as illustrated in FIGS. 2A and 2B, the first cover (110) can be rotated relative to the second cover (120) such that the second surface (112) faces the fourth surface (122) of the second cover (120). In this case, the display of the electronic device covered by the first cover (110) when the case (100) is closed can be viewed by the user. When the second surface (112) of the first cover (110) and the fourth surface (122) of the second cover (120) face each other, the first cover (110) and the second cover (120) can form a predetermined angle (θ). In a state where the second surface (112) of the first cover (110) and the fourth surface (122) of the second cover (120) face each other, the plurality of first mounting grooves (141) formed in the first cover (110) and the plurality of second mounting grooves (142) formed in the second cover (120) may face each other. In one embodiment, referring to FIGS. 2A and 2B, in a state where the second surface (112) of the first cover (110) and the fourth surface (122) of the second cover (120) face each other, the object (200) may be placed in any one first mounting groove (141) of the plurality of first mounting grooves (141) and any one second mounting groove (142) of the plurality of second mounting grooves (142). In one embodiment, the object (200) may be positioned partially in the first mounting groove (141) and partially in the second mounting groove (142) corresponding to the first mounting groove (141). As described above, among the plurality of mounting grooves (e.g., the plurality of first mounting grooves (141) and the plurality of second mounting grooves (142)), the corresponding first mounting grooves (141) and the second mounting grooves (142) may correspond to each other in the Z-axis direction when the case (100) is closed, as illustrated in FIG. 1B.

[0042] In one embodiment, the angle (θ) between the first cover (110) and the second cover (120) may change depending on the position of the object (200). For example, as the object (200) is positioned in the first mounting groove (141) and the second mounting groove (142) formed at a position adjacent to the connecting member (130), the angle (θ) between the first cover (110) and the second cover (120) may increase. Conversely, as the object (200) is positioned in the first mounting groove (141) and the second mounting groove (142) spaced apart from the connecting member (130), the angle (θ) between the first cover (110) and the second cover (120) may decrease.

[0043] In one embodiment, the magnetic body (M0) may be arranged along the outer shape of the object (200). For example, referring to FIGS. 2A and 2B, if the outer shape of the object (200) is cylindrical, the magnetic body (M0) may be arranged in a circular shape to correspond to the outer shape of the object (200). In one embodiment, if the outer shape of the object (200) (e.g., the object (300) of FIG. 3C) is an n-gon (n: a natural number greater than or equal to 3) (e.g., the object (300) of FIGS. 3C and 3D), the magnetic body (M0) may be arranged in an n-gon to correspond to the outer shape of the object (300).

[0044] In one embodiment, referring to FIGS. 2A and 2B, the number of magnetic bodies (M0) disposed on the object (200) may be plural. In one embodiment, the plurality of magnetic bodies (M0) may be disposed along an arc divided at about 45 degrees based on an imaginary circle corresponding to the outer shape of the object (200). In addition, the plurality of magnetic bodies (M0) may be disposed along arcs divided at various angles based on an imaginary circle corresponding to the outer shape of the object (200). Since the plurality of magnetic bodies (M0) are disposed inside the object (200) along the outer shape of the object (200), the object (200) can be magnetically coupled (e.g., magnetically coupled between the N pole and the S pole of FIG. 2B) with magnets (e.g., the first magnet (M1) and / or the second magnet (M2)) disposed in the first mounting groove (141) and the second mounting groove (142), regardless of the positions of the magnetic bodies (M0).

[0045] In one embodiment, referring to FIGS. 1B, 2A, and 2B, a first magnet (M1) may be disposed on a first cover (110). In one embodiment, the first magnet (M1) may be positioned adjacent to a first mounting groove (141). For example, the first magnet (M1) may be disposed inside the first cover (110) toward the first mounting groove (141). In one embodiment, the first magnet (M1) may be disposed along an inner surface of the first mounting groove (141). In one embodiment, the inner surface of the first mounting groove (141) may be a surface that comes into contact with the object (200). Therefore, the first magnet (M1) may be disposed close to the object (200) and may be magnetically coupled with a magnetic body (M0) of the object (200).

[0046] In one embodiment, referring to FIGS. 2A and 2B, a plurality of first magnets (M1) may be arranged inside the first cover (110) along the inner surface of the first mounting groove (141). The plurality of first magnets (M1) may be arranged inside the first cover (110) along a virtual circle having a radius of curvature equal to the radius of curvature of the outer shape of the object (200). For example, the plurality of first magnets (M1) may be arranged along an arc divided at about 45 degrees based on the virtual circle having a radius of curvature equal to the radius of curvature of the outer shape of the object (200). In addition, the plurality of first magnets (M1) may be arranged along arcs divided at various angles based on the virtual circle having a radius of curvature equal to the radius of curvature of the outer shape. Therefore, the first magnets (M1) may be arranged close to the object (200) and may be magnetically coupled with the magnetic body (M0) of the object (200).

[0047] In one embodiment, referring to FIGS. 1B, 2A, and 2B, the second magnet (M2) may be disposed on the second cover (120). In one embodiment, the second magnet (M2) may be positioned adjacent to the second mounting groove (142). For example, the second magnet (M2) may be disposed inside the second cover (120) toward the second mounting groove (142). In one embodiment, the second magnet (M2) may be disposed along the inner surface of the second mounting groove (142). In one embodiment, the inner surface of the second mounting groove (142) may be a surface that comes into contact with the object (200). Therefore, the second magnet (M2) may be disposed close to the object (200) and may be magnetically coupled with the magnetic body (M0) of the object (200).

[0048] In one embodiment, referring to FIGS. 2A and 2B, a plurality of second magnets (M2) may be arranged inside the second cover (120) along the inner surface of the second mounting groove (142). The plurality of second magnets (M2) may be arranged inside the second cover (120) along a virtual circle having a radius of curvature equal to a radius of curvature of the outer shape of the object (200). For example, the plurality of second magnets (M2) may be arranged along an arc divided at about 45 degrees based on a virtual circle having a radius of curvature equal to a radius of curvature of the outer shape of the object (200). In addition, the plurality of second magnets (M2) may be arranged along arcs divided at various angles based on a virtual circle having a radius of curvature equal to a radius of curvature of the outer shape. Accordingly, the second magnets (M2) may be arranged close to the object (200) to magnetically couple with the magnetic body (M0) of the object (200).

[0049] Although the above description assumes that the first magnet (M1) is placed on the first cover (110) and the second magnet (M2) is placed on the second cover (120), it may not be limited thereto. For example, the case (100) may include only one of the first magnet (M1) and the second magnet (M2).

[0050] According to one embodiment of the present disclosure, when the second surface (112) of the first cover (110) and the fourth surface (122) of the second cover (120) face each other, the object (200) may be positioned partially in the first mounting groove (141) and partially in the second mounting groove (142) corresponding to the first mounting groove (141). When the second surface (112) of the first cover (110) and the fourth surface (122) of the second cover (120) face each other, the angle (θ) formed by the first cover (110) and the second cover (120) may be fixed by the object (200) positioned between the first cover (110) and the second cover (120). The object (200) may have a magnetic body (M0) disposed therein that faces a first magnet (M1) facing a first mounting groove (141) inside the first cover (110) and / or a second magnet (M2) facing a second mounting groove (142) inside the second cover (120). The magnetic body (M0) of the object (200) may be magnetically coupled with the first magnet (M1) and / or the second magnet (M2). Accordingly, the object (200) may be fixed to the case (100) in a state where the second surface (112) of the first cover (110) and the fourth surface (122) of the second cover (120) face each other and the first cover (110) and the second cover (120) form a predetermined angle (θ). The angle (θ) between the first cover (110) and the second cover (120) can be stably fixed through the magnetic coupling force acting between the magnetic body (M0) of the object (200) and the first magnet (M1) and / or the second magnet (M2).

[0051] According to one embodiment, the first cover (110) and the second cover (120) may have a surface roughness higher on the surface that comes into contact with the object (200) than on the surface that does not come into contact with the object (200). In one embodiment, as illustrated in FIG. 2A, when the first cover (110) and the second cover (120) have mounting grooves (e.g., the first mounting groove (141), the second mounting groove (142)), at least one of the second surface (112) of the first cover (110) and the fourth surface (122) of the second cover (120) may have a surface roughness higher than either the first surface (111) of the first cover (110) or the third surface (121) of the second cover (120). For example, the second side (112) of the first cover (110) and / or the fourth side (122) of the second cover (120) may be formed of a material having a higher surface roughness (e.g., a material having a high coefficient of friction) than the first side (111) of the first cover (110) and the third side (121) of the second cover (120). In this case, the first cover (110) and the second cover (120) may be formed of at least different materials. In one embodiment, the second side (112) of the first cover (110) and the fourth side (122) of the second cover (120) may include micro-roughnesses and have a higher surface roughness than the first side (111) of the first cover (110) and the third side (121) of the second cover (120). Accordingly, the first cover (110) and the second cover (120) can have increased contact force with the object (200) as the surface that comes into contact with the object (200) is formed to have a higher surface roughness than the surface that does not come into contact with the object (200).

[0052] According to one embodiment, at least one surface among the inner surface of the first mounting groove (141) of the second surface (112) of the first cover (110) and the inner surface of the second mounting groove (142) of the fourth surface (122) of the second cover (120) may have a higher surface roughness than the other surface of the case (100). For example, the inner surface of the first mounting groove (141) of the second surface (112) of the first cover (110) may have a higher surface roughness than at least one of the second surface (112) of the first cover (110), the first surface (111) of the first cover (110), the third surface (121) of the second cover (120), and the fourth surface (122) of the second cover (120) excluding the inner surface of the first mounting groove (141). In addition, the inner surface of the second mounting groove (142) among the fourth surfaces (122) of the second cover (120) may have a higher surface roughness than at least one of the first surface (111) of the first cover (110), the second surface (112) of the first cover (110), the third surface (121) of the second cover (120), and the fourth surface (122) of the second cover (120) excluding the inner surface of the second mounting groove (142). In one embodiment, at least one surface among the inner surface of the first mounting groove (141) and the inner surface of the second mounting groove (142) may include micro-roughness and have a higher surface roughness than the other surface of the case (100). In one embodiment, at least one of the inner surface of the first mounting groove (141) and the inner surface of the second mounting groove (142) may be formed of a material having a higher surface roughness (e.g., a material having a high coefficient of friction) than the other surface of the case (100). Accordingly, the first cover (110) and the second cover (120) may have increased contact force with the object (200) as the surface that comes into contact with the object (200) is formed to have a higher surface roughness than the surface that does not come into contact with the object (200).

[0053] FIGS. 3A to 3D are drawings of a state in which the first cover and the second cover form a predetermined angle as an object is placed in a mounting groove between the first cover and the second cover according to one embodiment of the present disclosure.

[0054] According to one embodiment, the mounting grooves (240, 340) (e.g., mounting grooves (240, 340) of FIG. 3a, mounting grooves (340) of FIG. 3c) may be formed on either the second surface (112) of the first cover (110) or the fourth surface (122) of the second cover (120). For example, the mounting grooves (240, 340) may be formed only on the second surface (112) of the first cover (110). Alternatively, the mounting grooves (240, 340) may be formed only on the fourth surface (122) of the second cover (120). In the description related to FIGS. 3a to 3d to be described below, it will be assumed that the mounting grooves (240, 340) are formed on the fourth surface (122) of the second cover (120). However, the following description can be equally applied even when the fixing groove (240, 340) is formed only on the second surface of the first cover (110).

[0055] Additionally, in the following description, descriptions of configurations identical or similar to the configuration described above will be omitted.

[0056] According to one embodiment, as illustrated in FIG. 3A, a plurality of mounting grooves (240) (e.g., the second mounting grooves (142) of FIG. 1B) may be formed on the fourth surface (122) of the second cover (120) in which an object (200) (e.g., a pen input device, a stylus pen) may be positioned. In one embodiment, the plurality of mounting grooves (240) may be engraved grooves formed on the fourth surface (122) of the second cover (120). In one embodiment, the plurality of mounting grooves (240) may be arranged at predetermined intervals on the fourth surface (122) of the second cover (120). For example, the plurality of mounting grooves (240) may be arranged at predetermined intervals on the fourth surface (122) of the second cover (120), such as the plurality of second mounting grooves (142) arranged along the X-axis of FIG. 1B.

[0057] In one embodiment, the securing grooves (240, 340) may be formed in a shape corresponding to the appearance of the object (200, 300) (e.g., the object (200) of FIG. 3A, the object (300) of FIG. 3C). For example, referring to FIGS. 3A and 3B, the plurality of securing grooves (240) may be formed in a shape corresponding to the shape of the object (200) when the object (200) has a circular shape. In addition, referring to FIGS. 3C and 3D, the plurality of securing grooves (340) may be formed in a shape corresponding to the shape of a part of the object (300) when the object (300) has an n-gonal shape (n: a natural number greater than or equal to 3).

[0058] According to one embodiment, as illustrated in FIGS. 3A to 3D, the case (100) can be stood at various angles as the first cover (110) and the second cover (120) form a predetermined angle (θ) in the open state. For example, the first cover (110) and the second cover (120) can form a predetermined angle (θ) in a state where the second surface (112) of the first cover (110) and the fourth surface (122) of the second cover (120) face each other. The angle (θ) formed by the first cover (110) and the second cover (120) in a state where the second surface (112) of the first cover (110) and the fourth surface (122) of the second cover (120) face each other can be fixed by an object (200, 300) placed between the first cover (110) and the second cover (120). In one embodiment, the object (200, 300) may have a magnetic body (M0) disposed therein that faces a first magnet (M1) disposed inside the first cover (110) and / or a second magnet (M2) disposed inside the second cover (120). The magnetic body (M0) of the object (200, 300) may be magnetically coupled to the first magnet (M1) and / or the second magnet (M2). For example, when the first magnet (M1) is disposed inside the first cover (110) and the second magnet (M2) is disposed toward the mounting groove (240, 340) inside the second cover (120), the magnetic body (M0) of the object (200, 300) may be magnetically coupled to the first magnet (M1) and the second magnet (M2). Alternatively, when the first magnet (M1) is placed inside the first cover (110) and the second magnet (M2) is not placed inside the second cover (120), the magnetic body (M0) of the object (200, 300) can be magnetically coupled with the first magnet (M1). Alternatively, when the second magnet (M2) is placed inside the second cover (120) and the first magnet (M1) is not placed inside the first cover (110), the magnetic body (M0) of the object (200, 300) can be magnetically coupled with the second magnet (M2).Accordingly, the object (200, 300) can be fixed to the case (100) in a state where the second surface (112) of the first cover (110) and the fourth surface (122) of the second cover (120) face each other and the first cover (110) and the second cover (120) form a predetermined angle (θ). The angle (θ) between the first cover (110) and the second cover (120) can be stably maintained through the magnetic coupling force acting between the magnetic body (M0) of the object (200, 300) and the first magnet (M1) and / or the second magnet (M2).

[0059] According to one embodiment, the first cover (110) and the second cover (120) may have a surface roughness higher on the surface that comes into contact with the object (200, 300) than on the surface that does not come into contact with the object (200, 300). In one embodiment, referring to FIGS. 3a, 3b, 3c, and 3d, a second surface (112) of the first cover (110) that comes into contact with the object (200, 300) may not have a mounting groove (240, 340) formed thereon. Accordingly, the second surface (112) of the first cover (110) may be formed to have a higher surface roughness than the first surface (111) of the first cover (110), the third surface (121) of the second cover (120), and / or the fourth surface (122) of the second cover (120) so that the surface friction with the object (200, 300) can be increased when a part of the object (200, 300) is placed in the mounting groove (240, 340) of the second cover (120). In one embodiment, the second surface (112) of the first cover (110) may be formed of a material (e.g., a material having a high coefficient of friction) having a higher surface roughness than the first surface (111) of the first cover (110), the third surface (121) of the second cover (120), and / or the fourth surface (122) of the second cover (120). In one embodiment, the second surface (112) of the first cover (110) may include micro-roughnesses and have a higher surface roughness than the first surface (111) of the first cover (110), the third surface (121) of the second cover (120), and / or the fourth surface (122) of the second cover (120). Accordingly, the first cover (110) may have a surface rougher on the surface (e.g., the second surface (112)) that comes into contact with the object (200, 300) than on the surface that does not come into contact with the object (200, 300), thereby increasing the contact force with the object (200, 300).

[0060] According to one embodiment, the fourth surface (122) of the second cover (120) may have a higher surface roughness than the first surface (111) of the first cover (110) and / or the third surface (121) of the second cover (120), in addition to the second surface of the first cover (110). In one embodiment, the fourth surface (122) of the second cover (120) may be formed of a material having a higher surface roughness than the first surface (111) of the first cover (110) and / or the third surface (121) of the second cover (120). In one embodiment, the fourth surface (122) of the second cover (120) may include micro-roughnesses and have a higher surface roughness than the first surface (111) of the first cover (110) and / or the third surface (121) of the second cover (120). Accordingly, the second cover (120) can have increased contact force with the object (200, 300) by forming the surface roughness (e.g., the fourth surface (122)) that comes into contact with the object (200, 300) higher than the surface that does not come into contact with the object (200, 300).

[0061] According to one embodiment, the inner surface of the mounting groove (240, 340) among the fourth surface (122) of the second cover (120) may have a higher surface roughness than the other surfaces of the case (100). For example, the inner surface of the mounting groove (240, 340) among the fourth surface (122) of the second cover (120) may have a higher surface roughness than at least one surface among the fourth surface (122) of the second cover (120) excluding the mounting groove (240, 340), the third surface (121) of the second cover (120), the first surface (111) of the first cover (110), and / or the second surface (112) of the first cover (110). In one embodiment, the inner surface of the mounting groove (240, 340) may be formed of a material having a higher surface roughness than at least one of the fourth surface (122) of the second cover (120), the third surface (121) of the second cover (120), the first surface (111) of the first cover (110), and / or the second surface (112) of the first cover (110), excluding the mounting groove (240, 340). In one embodiment, the inner surface of the mounting groove (240, 340) may include micro-roughness and have a higher surface roughness than at least one of the fourth surface (122) of the second cover (120), the third surface (121) of the second cover (120), the first surface (111) of the first cover (110), and / or the second surface (112) of the first cover (110), excluding the mounting groove (240, 340).

[0062] FIGS. 4A and 4B are drawings of a state in which the first cover and the second cover form a predetermined angle as an object is placed between the first cover and the second cover according to one embodiment of the present disclosure.

[0063] According to one embodiment, as illustrated in FIGS. 4A and 4B, the second surface (112) of the first cover (110) and the fourth surface (122) of the second cover (120) may not have a mounting groove (240, 340). In this case, when the second surface (112) of the first cover (110) and the fourth surface (122) of the second cover (120) face each other, the angle (θ) formed by the first cover (110) and the second cover (120) may be fixed through the magnetic coupling of the magnetic body (M0) of the object (200) and the first magnet (M1) and / or the second magnet (M2).

[0064] According to one embodiment, the angle (θ) formed by the first cover (110) and the second cover (120) can be fixed by making the surface roughness of the second surface (112) of the first cover (110) and the fourth surface (122) of the second cover (120) in contact with the object (200) higher than that of the other surfaces, thereby increasing the contact force between the second surface (112) of the first cover (110) and the fourth surface (122) of the second cover (120) of the object (200).

[0065] In one embodiment, the object (200) may include a clip that can be secured to the first cover (110) and / or the second cover (120). For example, the object (200) may include a clip formed at one end, and may be secured to the first cover (110) and / or the second cover (120) as the clip is secured to the first cover (110) and / or the second cover (120).

[0066] FIGS. 5A and 5B are exploded views of the components that make up an object according to one embodiment of the present disclosure.

[0067] According to one embodiment, as illustrated in FIGS. 5A and 5B , the object (200) (e.g., the object (200) of FIG. 3A and / or the object (300) of FIG. 3C ) may be a pen input device (e.g., a stylus pen). In one embodiment, the object (200) may include a pen device (201), a pen case (202), a pen grip (203), and / or a pen handle (204). At least one of the above-described components may be omitted or at least one component may be added. The pen device (201) may be a main body of the pen input device and may be configured to be communicatively paired with an electronic device to enable input (e.g., touch, drawing) to the electronic device. In one embodiment, the pen grip (203) may be configured to be coupled to the pen device (201) to assist a user in easily holding the pen device (201). The pen handle (204) may be configured to be connected to the pen grip (203) and positioned at the end of the object (200). In one embodiment, the pen handle (204) may be formed in various shapes to provide an aesthetic feel to the user and protect the pen device (201) from external impact. In one embodiment, the pen case (202) may be configured to accommodate the pen grip (203) coupled with the pen device (201) and protect the pen device (201) from external impact.

[0068] In one embodiment, referring to FIG. 5A, the pen handle (204) may be formed in a shape that protrudes from the outer periphery of the pen grip (203). In this case, when the second surface (112) of the first cover (110) and the fourth surface (122) of the second cover (120) face each other and the first cover (110) and the second cover (120) form a predetermined angle (θ), the object (200) may be positioned between the first cover (110) and the second cover (120) with the pen grip (203) having a relatively larger area than the pen handle (204) and the pen handle (204) located outside the case (100). Accordingly, when the object (200) is removed from the case (100), the user may hold the pen handle (204) to separate the object (200) from the case (100).

[0069] In one embodiment, referring to FIG. 5B, the pen handle (204) may be formed to have the same size as the outer circumference of the pen grip (203). For example, the pen handle (204) may be formed to have the same size (e.g., the same diameter) as the pen grip (203) and may be configured to refer to the distal end of the pen grip (203). In this case, the object (200) may be positioned between the first cover (110) and the second cover (120) such that the second surface (112) of the first cover (110) and the fourth surface (122) of the second cover (120) face each other and the first cover (110) and the second cover (120) form a predetermined angle (θ). Accordingly, the object (200) can have a high degree of freedom in placement relative to the case (100) because the pen handle (204) does not have to be located outside the case (100).

[0070] According to various embodiments, each component (e.g., a module or a program) of the above-described components may include one or more entities, and some of the entities may be separated and arranged in other components. According to various embodiments, one or more components or operations of the aforementioned components may be omitted, or one or more other components or operations may be added. Alternatively or additionally, a plurality of components (e.g., a module or a program) may be integrated into a single component. In such a case, the integrated component may perform one or more functions of each of the plurality of components identically or similarly to those performed by the corresponding component among the plurality of components prior to the integration. According to various embodiments, the operations performed by a module, program, or other component may be executed sequentially, in parallel, iteratively, or heuristically, or one or more of the operations may be executed in a different order, omitted, or one or more other operations may be added.
