The five regions below the 11th region S11, 12th region S12, 13th region S13, 14th region S14, and 15th region S15 are defined as the 16th region S16, 17th region S17, 18th region S18, 19th region S19, and 20th region S20, respectively. The five regions below the 16th region S16, 17th region S17, 18th region S18, 19th region S19, and 20th region S20 are defined as the 21st region S21, 22nd region S22, 23rd region S23, 24th region S24, and 25th region S25, respectively, from left to right.

[0020] Of these, rear camera 15 is provided in fifth region S5, and battery 17 is housed inside first combined region 53 which combines seventh region S7 to ninth region S9, twelfth region S12 to fourteenth region S14, and seventeenth region S17 to nineteenth region S19. Operation buttons 19 are provided on the outer surface of main body 13 in second combined region 55 which combines third region S3, fourth region S4, fifth region S5, tenth region S10, and fifteenth region S15. When mobile terminal 11 is viewed from the back, the center of battery 17 is located inside thirteenth region S13.

[0021] FIG. 4 is a cross-sectional view taken along the line BB in FIG. The mobile terminal 11 further includes a circuit board 57. When the mobile terminal 11 is seen through from the rear, the circuit board 57 is arranged along the periphery of the battery 17. That is, the circuit board 57 is provided inside a rectangular frame-shaped region 59 (see FIG. 3) that combines the first region S1, the second region S2, the third region S3, the fourth region S4, the fifth region S5, the sixth region S6, the tenth region S10, the eleventh region S11, the fifteenth region S15, the sixteenth region S16, the twentieth region S20, the twenty-first region S21, the twenty-second region S22, the twenty-third region S23, the twenty-fourth region S24, and the twenty-fifth region S25 shown in FIG.

[0022] In mobile terminal 11, circuit board 57 has hole 61, and battery 17 is inserted into hole 61. Circuit board 57 has a doughnut shape (a square shape) that surrounds hole 61 entirely, but may have a shape that surrounds at least a portion of hole 61 (for example, a U-shape).

[0023] 5 is a perspective view of the rear surface of FIG. 2 as seen obliquely from above. The operation buttons 19 are provided on the outer surface of the main body 13, that is, in an opening cut out across the combined portion of the front cover 35 and rear cover 37. The operation buttons 19 include, for example, a power button 63 and a volume button 65. In addition, the outer surface of the main body 13 is also provided with an opening / closing cover 67 for the USB port, an expansion bus connector 69 for the cradle, a DC input terminal 71, a headset terminal, etc.

[0024] FIG. 6 is an exploded perspective view of essential parts of the mobile terminal 11 shown in FIG. 5, rotated 180 degrees around an axis perpendicular to the rear surface. The battery 17 has a pair of locking claws 73 protruding from a short side thereof at a distance from one another. The locking claws 73 lock onto the rear cover 37, so that the battery 17 is held in the main body 13 while being placed on a battery mounting portion 75 formed on the rear cover 37. The battery 17 held in the main body 13 can be removed from the main body 13 by releasing the lock button 43 and operating the unlocking projection 41. The circuit board 57 is provided with terminals 77 and 79 for power supply, current detection, etc., which are in electrical contact with the battery 17 held in the main body 13. Electronic components 81 and 83, such as a processor and a power supply IC, are mounted on the circuit board 57 on the side where the rear camera 15 is provided, across the hole 61. Wireless electronic components 85 (e.g., a wireless circuit) are mounted on the circuit board 57 on the side opposite the side where the rear camera 15 is provided, across the hole 61.

[0025] When viewed from the rear, the circuit board 57 has optional areas on its upper edge where the top cover 47 is provided and on the side where the rear camera 15 is provided, across the hole 61. A card reader or the like can be connected to the optional areas. When viewed from the rear, the circuit board 57 has an area for arranging a wireless system on the side opposite the side where the rear camera 15 is provided, across the hole 61. Connectors 87, such as a DC input terminal 71, are mounted on the edge of the circuit board 57 on the side where the wireless system is arranged. The front cover 35 has terminals 89 that connect the circuit board 57 to the power supply circuits and control circuits of the display 21 and the touch panel.

[0026] FIG. 7 is a cross-sectional view taken along line AA in FIG. The mobile terminal 11 is attached by inserting the battery 17 into the hole 61. The surface of the battery 17 on the attachment side is supported by a chassis 91 fixed to the front cover 35 via a battery mounting portion 75. The chassis 91 is arranged so as to cover the back surface of the display 21 exposed in the hole 61. Therefore, when the battery 17 is attached or detached, the chassis 91 is exposed at the bottom of the hole 61. The chassis 91 is capable of suppressing heat and electromagnetic wave voltage.

[0027] The battery 17 is available in a thin standard type and a large-capacity type that is thicker than the standard type. Figure 7 shows the large-capacity type battery 17. The battery 17 has a battery circuit section 95 on the mounting side of the battery main body section 93. A sealant 97 is sandwiched between the front cover 35 and the rear cover 37, thereby sealing the joint watertight.

[0028] FIG. 8 is an enlarged view of part C in FIG. An annular seal 99 is fitted around the outer periphery of the mounting side of the battery 17. When the battery 17 is mounted on the rear cover 37, this seal 99 comes into close contact with the fitting portion of the rear cover 37, creating a watertight seal between the battery 17 and the rear cover 37.

[0029] The display 21, which is disposed on the opposite side of the chassis 91 from the battery 17, has a liquid crystal panel 101. A touch panel 103 is attached to the surface of the liquid crystal panel 101 opposite the chassis 91. The touch panel 103 detects a change in current when touched and identifies the touched position from the amount of change. The front side of the touch panel 103 is protected by a cover glass 105. Furthermore, a functional film 107 such as an AR (Anti-Reflection) / AG (Anti-Glare) film is attached to the front side of the cover glass 105. The display 21 is configured to include the liquid crystal panel 101, touch panel 103, functional film 107, etc.

[0030] Next, the operation of the above-described configuration will be described.

[0031] Mobile terminal 11 according to this embodiment has a rectangular shape in a plan view and includes main body 13 having display 21 on its surface, rear camera 15 (an example of a camera) provided on the rear surface of main body 13, battery 17 housed in main body 13, and operation buttons 19 provided on the exterior surface of main body 13. When viewed from the rear, main body 13 is divided into 25 regions consisting of a matrix by imaginary lines 51 that divide each of two orthogonal sides of main body 13 into five equal parts. With one of the two sides defined as the top side, the five regions including the top side are defined, from left to right, as first region S1, second region S2, third region S3, fourth region S4, and fifth region S5. The five regions below first region S1, second region S2, third region S3, fourth region S4, and fifth region S5 are defined, from left to right, as sixth region S6, seventh region S7, eighth region S8, ninth region S9, and tenth region S10. The five regions below the sixth region S6, the seventh region S7, the eighth region S8, the ninth region S9, and the tenth region S10 are defined as the eleventh region S11, the twelfth region S12, the thirteenth region S13, the fourteenth region S14, and the fifteenth region S15, from left to right. The five regions below the eleventh region S11, the twelfth region S12, the thirteenth region S13, the fourteenth region S14, and the fifteenth region S15 are defined as the sixteenth region S16, the seventeenth region S17, the eighteenth region S18, the nineteenth region S19, and the twentieth region S20, from left to right. The five areas below the 16th area S16, the 17th area S17, the 18th area S18, the 19th area S19, and the 20th area S20 are defined as the 21st area S21, the 22nd area S22, the 23rd area S23, the 24th area S24, and the 25th area S25, from left to right. The rear camera 15 is provided in the 5th area S5. The battery 17 is housed inside a first merged area 53 that combines the 7th area S7 to the 9th area S9, the 12th area S12 to the 14th area S14, and the 17th area S17 to the 19th area S19. The operation buttons 19 are provided on the outer surface of the main body 13 in a second merged area 55 that combines the 3rd area S3, the 4th area S4, the 5th area S5, the 10th area S10, and the 15th area S15. When the mobile terminal 11 is viewed from the rear, the center of the battery 17 is within the thirteenth region S13.

[0032] In the mobile terminal 11 according to this embodiment, the main body 13 is formed in the shape of a rectangular plate in a plan view. The mobile terminal 11 is generally formed in a rectangular shape in a plan view. The rectangular shape does not exclude squares. The main body 13 has a rectangular display 21 disposed on one surface of the plate. The main body 13 has a rear camera 15 on the back surface opposite the front surface. The main body 13 also houses a battery 17 on the back surface. Furthermore, the main body 13 has an operation button 19 on its outer surface. This outer surface may include the front surface, back surface, or outer peripheral surface of the main body 13. That is, the operation button 19 may be provided on any of the front surface, back surface, or outer peripheral surface of the main body 13. In this embodiment 1, the operation button 19 is provided on the outer peripheral surface.

[0033] Here, when viewed from the rear, the main body 13 can be considered as being divided into 25 matrix regions (matrix regions) by imaginary lines 51 that divide each of two orthogonal sides into five equal parts. These matrix regions can be defined as a first region S1 to a 25th region S25 from left to right and from top to bottom.

[0034] Furthermore, the seventh region S7 to the ninth region S9, the twelfth region S12 to the fourteenth region S14, and the seventeenth region S17 to the nineteenth region S19 can be defined as a merged first merged region 53.

[0035] Furthermore, the third region S3, the fourth region S4, the fifth region S5, the tenth region S10, and the fifteenth region S15 can be defined as a second merged region 55.

[0036] In the mobile terminal 11, functional units such as the rear camera 15, battery 17, and operation buttons 19 are arranged in specific regions (positions) of the main body 13 defined in this manner. The rear camera 15 is provided in the fifth region S5. The operation buttons 19 are provided in the first combined region 53. This region allocation is when the main body 13 is viewed from the rear. When the mobile terminal 11 is used, it is operated while looking straight at the display 21 on the front side. Therefore, when the display 21 is viewed straight on, the matrix regions are allocated in a horizontally reversed manner. In other words, when the mobile terminal 11 is held with the display 21 viewed straight on, for example, the rear camera 15 arranged in the fifth region S5 is located on the rear side of the upper left of the display 21 (see FIG. 1). In this case, when the mobile terminal 11 is held in the left hand, the 20th region S20 and the 25th region S25 of the main body 13 are regions suitable for holding. When the mobile terminal 11 is held in the right hand, the 16th region S16 and the 21st region S21 of the main body 13 are suitable for gripping.

[0037] Furthermore, when the orientation of the mobile terminal 11 is changed between portrait and landscape, the main body 13 is rotated, for example, 90 degrees clockwise while the display 21 is viewed from the front. Then, the rear camera 15 located in the fifth region S5 on the back surface is positioned on the upper right rear side of the portrait-oriented display 21. In this case, when the mobile terminal 11 is held in the left hand, the 21st region S21 and the 22nd region S22 of the main body 13 are regions suitable for holding. Furthermore, when the mobile terminal 11 is held in the right hand, the 1st region S1 and the 2nd region S2 of the main body 13 are regions suitable for holding.

[0038] Note that the portrait orientation refers to an orientation of mobile terminal 11 in which mobile terminal 11 is long vertically. The landscape orientation refers to an orientation of mobile terminal 11 in which mobile terminal 11 is long horizontally. Note that when main body 13 is square, two perpendicular sides have the same length, so either side may be treated as the vertical side or the horizontal side, i.e., either side may be used as the basis for defining the portrait orientation or the landscape orientation.

[0039] In this way, in mobile terminal 11, rear camera 15 is arranged in fifth area S5 and operation button 19 is provided in second merged area 55, so even if main body 13 is normally held with either the left or right hand, fingers do not interfere with fifth area S5 and second merged area 55. Furthermore, even if mobile terminal 11 is switched between portrait and landscape orientations, that is, even if main body 13 is normally held with either the left or right hand, fingers do not interfere with fifth area S5 and second merged area 55.

[0040] In this way, mobile terminal 11 can be positioned so that rear camera 15 is near the top end of main body 13, whether main body 13 is oriented vertically or horizontally. Also, operation buttons 19 can be positioned so that they are not hidden by the hand holding main body 13, whether main body 13 is oriented vertically or horizontally and whether main body 13 is held in the right hand or the left hand.

[0041] As a result, even when the mobile terminal 11 is held in portrait or landscape orientation, the rear camera 15, operation buttons 19, and other operating parts are not hidden by the hand holding the mobile terminal 11, thereby preventing a decrease in operability.

[0042] Additionally, the mobile terminal 11 accommodates the battery 17 within the first merged region 53. The first merged region 53 is located as an island in the center surrounded by the first region S1, the second region S2, the third region S3, the fourth region S4, the fifth region S5, the sixth region S6, the tenth region S10, the eleventh region S11, the fifteenth region S15, the sixteenth region S16, the twentieth region S20, the twenty-first region S21, the twenty-second region S22, the twenty-third region S23, the twenty-fourth region S24, and the twenty-fifth region S25 along the outer circumferential surface of the main body 13. Furthermore, the battery 17 is located within the thirteenth region S13, whose center is the center of the first merged region 53.

[0043] As a result, the center of gravity of battery 17, which has a relatively large mass, is positioned on the back surface close to the center of gravity of main body 13 excluding battery 17. Therefore, when mobile terminal 11 is held in portrait or landscape orientation, the distance from the center of gravity of battery 17 to the handle does not change significantly, compared to a structure in which battery 17 is attached close to one side on the back surface and offset.

[0044] As a result, even when the mobile terminal 11 is held vertically or horizontally, the center of gravity of the battery 17 does not come to the side that is not being held, reducing the burden on the user who holds the main body 13 for a long time and preventing a decrease in operability.

[0045] FIG. 9 is a schematic diagram showing another example in which the rear surface of the main body 13 is divided into regions consisting of a matrix of 25 divisions. As described above, the mobile terminal 11 is generally formed in a rectangular shape in a plan view. The mobile terminal 11 is divided into 25 matrix regions by dividing each of two orthogonal sides of the main body 13 into five equal parts by imaginary lines 51. One of the two sides is defined as the top side, with one side being located on the upper side. When the main body 13 is rectangular, one of the two sides is the long side and the other is the short side. As shown in FIG. 3, when the long side is defined as the top side, the main body 13 is oriented horizontally (horizontally long). As shown in FIG. 9, when the short side is defined as the top side, the main body 13 is oriented vertically (vertically long). That is, the reference orientation in FIG. 3 is horizontal, and the reference orientation in FIG. 9 is vertical.

[0046] When the areas from the first area S1 to the 25th area S25 are assigned according to the above arrangement pattern in these two orientations, landscape and portrait, in the initial position before rotation, the rear camera 15, which is located on the rear surface, for example, in the 5th area S5, is located on the upper left rear side of the display 21 when viewed from the front, in both landscape and portrait orientations.

[0047] When main body 13 is oriented horizontally with the long side shown in Fig. 3 defined as the top side and turned vertically, rear camera 15 arranged in fifth region S5 on the back surface is located on the rear side at the upper right of vertically oriented display 21. The position of rear camera 15 is opposite the position of rear camera 15 in the case of main body 13 oriented vertically with the short side shown in Fig. 9 defined as the top side, i.e., on the rear side at the upper left of display 21.

[0048] 9 is defined as the top side, rear camera 15, which is located in fifth region S5 on the back side, is positioned on the upper right rear side of horizontally oriented display 21. The position of rear camera 15 is opposite the position of rear camera 15 in the case of horizontally oriented main body 13, which is defined as the top side of long side shown in FIG. 3, i.e., the upper left rear side of display 21.

[0049] In other words, the mobile terminal 11 has a matrix area defined by "placing one of the two sides (long side and short side) on the upper side," so whether the reference orientation is landscape or portrait, the rear camera 15 and operation button 19 are arranged on either the left or right side of the upper side.

[0050] In the mobile terminal 11, the main body 13 may have a rectangular shape in a plan view. With two of the four short sides of the back surface positioned on the left and right sides of the main body 13, matrix regions may be defined as a first region S1 to a 25th region S25.

[0051] In this mobile terminal 11, the main body 13 is formed in a rectangular shape in a plan view. As shown in Fig. 3, the matrix area is defined in this rectangular main body 13 with the two short sides positioned on the left and right of the main body 13. That is, the matrix area is defined in the mobile terminal 11 in a landscape orientation with the long side at the top (see Fig. 3).

[0052] When mobile terminal 11 having a matrix area defined in landscape orientation is in landscape orientation, rear camera 15 is arranged on the rear side at the upper left of display 21 when viewed from the front. When mobile terminal 11 having a matrix area defined in landscape orientation is in portrait orientation, rear camera 15 is arranged on the rear side at the upper right of display 21 when viewed from the front.

[0053] The mobile terminal 11 may further include a circuit board 57. The circuit board 57 may be arranged along the periphery of the battery 17 when the mobile terminal 11 is seen through from the rear.

[0054] In this mobile terminal 11, a circuit board 57 is arranged around the periphery of the battery 17. The battery 17 is arranged in an island shape in the center of the back surface. The circuit board 57 is arranged so as to surround the periphery of the battery 17. In terms of the matrix region, the circuit board 57 is arranged in a rectangular frame-shaped region 59 that combines the first region S1, the second region S2, the third region S3, the fourth region S4, the fifth region S5, the sixth region S6, the tenth region S10, the eleventh region S11, the fifteenth region S15, the sixteenth region S16, the twentieth region S20, the twenty-first region S21, the twenty-second region S22, the twenty-third region S23, the twenty-fourth region S24, and the twenty-fifth region S25. In the mobile terminal 11, the circuit board 57 is arranged so as not to overlap the battery 17. This prevents the thickness of the mobile terminal 11 from increasing when the battery is attached, compared to when these are stacked. Furthermore, the battery 17, which has a relatively large mass, can be fixed securely and strongly to the chassis 91 of the main body 13, etc., without interfering with the circuit board 57 in the thickness direction.

[0055] The mobile terminal 11 may be arranged such that the circuit board 57 has a hole 61 into which the battery 17 is inserted.

[0056] In this mobile terminal 11, circuit board 57 has hole 61. Battery 17 is inserted into hole 61 and disposed therein. Since battery 17 is disposed in the center of the back surface, hole 61 is also formed in the center of the back surface. In other words, circuit board 57 is formed in an annular shape with square-shaped hole 61 in the center of the back surface. This annular circuit board 57 is arranged at high density without creating wasted space, following the rectangular frame-shaped region 59 described above. In other words, mobile terminal 11 has a shape and arrangement that allows battery 17 and circuit board 57 to be arranged at high density in three dimensions, thereby achieving a compact overall size of mobile terminal 11.

[0057] Furthermore, in mobile terminal 11, battery 17 can be disposed by passing through hole 61 of circuit board 57, which further prevents the thickness of mobile terminal 11 from increasing when the battery is attached. Since mobile terminal 11 can dispose battery 17, which is relatively thick, by inserting it into hole 61 of circuit board 57, it is possible to reduce the thickness of main body 13 to a value approximately equal to the thickness of battery 17, for example.

[0058] In the mobile terminal 11, a pair of protrusions 45 may be detachably provided on the rear surface of the main body 13, along a pair of parallel sides of the rectangular battery 17 housed on the rear surface.

[0059] In this mobile terminal 11, a pair of protrusions 45 may be detachably provided on the back surface of the main body 13. The pair of protrusions 45 are arranged parallel to a pair of parallel sides of a rectangular battery 17 stored in the back surface. The battery 17 may be available in a thin standard type and a high-capacity type that is thicker than the standard type. On the back surface on which the standard type battery 17 is attached, the pair of protrusions 45 protrude beyond the battery 17. Therefore, in a mobile terminal 11 equipped with a standard type battery 17, the pair of protrusions 45 protruding from the back surface can be used as finger hooks, improving the grip of the main body 13. Furthermore, on the back surface on which the high-capacity type battery 17 is attached, the battery 17 and the pair of protrusions 45 are approximately the same height from the back surface. As a result, the high-capacity type battery 17 has a smaller step from the back surface, preventing other components from directly colliding with the side of the battery.

[0060] Furthermore, the pair of protrusions 45 can be removed from the back surface to expose connection terminals and the like provided inside the main body 13. This allows the pair of protrusions 45 to function as cover members that cover connection terminals for a card reader such as a barcode reader or that open an option area.

[0061] Therefore, according to the mobile terminal 11 of this embodiment, whether the mobile terminal 11 is held in portrait or landscape orientation, the burden on the user when holding the mobile terminal 11 can be reduced, and a decrease in the operability of the mobile terminal 11 can be suppressed.

[0062] Although various embodiments have been described above with reference to the drawings, it goes without saying that the present disclosure is not limited to such examples. It is clear that a person skilled in the art can conceive of various modifications or alterations within the scope of the claims, and it is understood that these also naturally fall within the technical scope of the present disclosure. Furthermore, the components of the above-described embodiments may be combined in any manner without departing from the spirit of the invention.

[0063] For example, in the above embodiment, the top cover 47 provided on the back surface of the main body 13 may be a protruding portion that protrudes further than the battery 17. In this case, the protruding portion serving as the top cover 47 may be provided to be removable. On the back surface on which the standard-type battery 17 is attached, the protruding portion serving as the top cover 47 protrudes further than the battery 17. Therefore, in a mobile terminal 11 on which the standard-type battery 17 is attached, the protruding portion serving as the top cover 47 protruding from the back surface can be used as a finger hook, improving the grip of the main body 13. Furthermore, on the back surface on which the large-capacity battery 17 is attached, the height of the battery 17 and the protruding portion serving as the top cover 47 from the back surface may be approximately the same. This reduces the step of the large-capacity battery 17 from the back surface, preventing other components from directly colliding with the side of the battery.

[0064] In the above embodiment, a card reader or the like can be connected to the option area on the back surface of the main body 13, but this is not limited to this. The option area may also be capable of connecting electronic devices other than a card reader. This electronic device may include an external USB connector (USB receptacle) that can be connected to a USB cable or USB plug connected to an external device. This electronic device may have an external LAN connector (LAN receptacle) that can be connected to a LAN cable or LAN plug connected to an external device. Furthermore, instead of attaching the top cover 47 and the pair of protrusions 45 so that the various functional components and option area are freely exposed, options (electronic devices such as the card reader or connectors described above) may be attached directly to the top cover 47 and the pair of protrusions 45, or the options may be attached to the positions of the top cover 47 and the pair of protrusions 45 instead of the top cover 47 and the pair of protrusions 45. In this case, the optional electronic device itself becomes a protrusion installed on the back surface of the main body 13.

[0065] Further explanation will be given regarding installation examples of options on the back surface of the main body 13. FIG. 10 is a diagram illustrating a first installation example of options on the main body 13. In FIG. 10, a barcode reader 111 is attached to the top cover 47. FIG. 11 is a diagram illustrating a second installation example of options on the main body 13. In FIG. 11, the barcode reader 111 is attached to one of the pair of protrusions 45. FIG. 12 is a diagram illustrating a third installation example of options on the main body 13. In FIG. 12, the barcode reader 111 is attached to the top cover 47, and a LAN connector 113 is attached to one of the pair of protrusions 45. FIG. 13 is a diagram illustrating a fourth installation example of options on the main body 13. In FIG. 13, the barcode reader 111 is attached to the top cover 47, and a magnetic card reader 115 is attached to one of the pair of protrusions 45. FIG. 14 is a diagram illustrating a fifth installation example of options on the main body 13. In Fig. 14, a barcode reader 111 is attached to the top cover 47, and a contact IC card reader 117 is attached to one of the pair of protrusions 45. Fig. 15 is a diagram showing a sixth example of installing options on the main body 13. In Fig. 15, a barcode reader 111 is attached to the top cover 47, and a LAN connector 119 is attached to one of the pair of protrusions 45. Note that the combinations of electronic devices installed in the top cover 47 and the pair of protrusions 45 are not limited to the combinations in Figs. 10 to 16, and other combinations may be used.

[0066] 10 to 15, a second protrusion (for example, top cover 47 or an option) may be provided along a side of battery 17 on the upper side of main body 13 that extends substantially left and right on the back surface of main body 13, in other words, a side that is substantially perpendicular to a pair of parallel sides that extend substantially vertically on the left and right. This enables mobile terminal 11 to perform payment processing and extend wired communication using various optional electronic devices, and provides a finger rest when mobile terminal 11 is held vertically, for example.

[0067] The same applies to first protrusions (for example, protrusion 45, optional) provided along a pair of parallel sides extending substantially in the left-right direction on the back surface of main body 13. In this case, mobile terminal 11 can perform payment processing or extend wired communication using various optional electronic devices, or can provide a finger rest when mobile terminal 11 is held horizontally, for example.

[0068] Furthermore, this second protrusion may be provided so as to be detachable from the main body 13. This allows the optional protrusion to be dispensed with when the mobile terminal 11 does not require payment processing or expansion of wired communication using USB or LAN. Furthermore, when the mobile terminal 11 is rarely held in portrait orientation, the top cover 47 does not need to be a protrusion. This allows for the addition of various functions to the mobile terminal 11 while also reducing the weight of the mobile terminal 11. [Industrial Applicability]

[0069] The present disclosure is useful for mobile terminals and the like that can reduce the burden on a user when holding a mobile terminal, regardless of whether the mobile terminal is held vertically or horizontally, and can suppress a decrease in the operability of the mobile terminal.
