[0022] In the mobile terminal 11, the circuit board 57 has a hole 61, and the battery 17 is inserted and disposed in this hole 61. The shape of the circuit board 57 is a donut shape (a square shape) that surrounds the entire hole 61 by having the hole 61, but it may have a shape that surrounds at least a part of the hole 61 (for example, a U-shape or a C-shape).

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

[0024] FIG. 6 is an exploded perspective view of the essential parts of the mobile terminal 11 shown in FIG. 5, disassembled in a direction rotated 180 degrees around an axis perpendicular to the rear surface. A pair of locking claws 73 protrude from the short side of the battery 17. The locking claws 73 lock the battery 17 to the rear cover 37, and the battery 17 is held in the main body 13 in a state of being placed on a battery placement section 75 formed on the rear cover 37. The battery 17 held in the main body 13 can be detached from the main body 13 by releasing the lock button 43 and operating the lock release protrusion 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., wireless circuits) 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 an option area on the upper edge side where the top cover portion 47 is provided and on the side where the rear camera 15 is provided across the hole portion 61. A card reader or the like can be connected to the option area. 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 portion 61. A connector 87 such as a DC input terminal 71 is mounted on the board edge portion of the circuit board 57 on the side of the area for arranging the wireless system. The front cover 35 has a terminal portion 89 for connecting the power supply circuit and control circuit of the display 21 and the touch panel to the circuit board 57.

[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 is provided with a battery circuit section 95 on the mounting side of the battery main body section 93. A sealant 97 is sandwiched between the joints of the front cover 35 and the rear cover 37, thereby sealing the joints watertightly.

[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 to provide 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 to 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, the touch panel 103, the functional film 107, etc.

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

[0031] The mobile terminal 11 according to the present embodiment is rectangular in plan view and includes a main body 13 having a display 21 on its surface, a rear camera 15 (one example of a camera) provided on the back of the main body 13, a battery 17 housed in the main body 13, and an operation button 19 provided on the outer surface of the main body 13. When viewed from the back, the main body 13 is divided into 25 areas consisting of a matrix by imaginary lines 51 that divide each of two orthogonal sides of the main body 13 into five equal parts. With one of the two sides defined as the top side located on the upper side, the five areas including the top side are defined as the first area S1, the second area S2, the third area S3, the fourth area S4, and the fifth area S5 from the left. The five areas below the first area S1, the second area S2, the third area S3, the fourth area S4, and the fifth area S5 are defined as the sixth area S6, the seventh area S7, the eighth area S8, the ninth area S9, and the tenth area S10 from the left. 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, in order from the left. 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, in order from the left. 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, in order from the left. The rear camera 15 is provided in the 5th area S5. The battery 17 is stored inside the first merged area 53, which is a merged area of ​​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 button 19 is provided on the outer surface of the main body 13 in the second merged area 55, which is a merged area of ​​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 a rectangular plate shape 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 arranged on one surface of the plate. The main body 13 has a rear camera 15 on the back surface opposite to 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 the 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, the main body 13 can be considered as being divided into 25 matrix regions (matrix regions) when viewed from the rear by imaginary lines 51 that divide each of two perpendicular sides into 5 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] In addition, 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 parts such as the rear camera 15, the battery 17, and the operation button 19 are arranged in a specific area (position) of the main body 13 defined in this way. The rear camera 15 is provided in the fifth area S5. The operation button 19 is provided in the first merged area 53. This area allocation is when the main body 13 is viewed from the back. When using the mobile terminal 11, the user operates the display 21 on the front side while looking at it from the front. Therefore, when the display 21 is viewed from the front, the above-mentioned matrix area is allocated in a left-right inverted manner. In other words, when the mobile terminal 11 is held while looking at the display 21 from the front, the rear camera 15 arranged in the fifth area S5, for example, is located on the rear side at 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 twentieth area S20 and the twenty-fifth area S25 of the main body 13 are suitable areas 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 with the display 21 viewed from the front. Then, the rear camera 15 arranged in the fifth region S5 on the back surface is arranged on the upper right rear side of the portrait-oriented display 21. At this time, 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 suitable regions for holding. 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 suitable regions for holding.

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

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

[0040] In this way, mobile terminal 11 can be positioned so that rear camera 15 is located 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 vertically or horizontally, 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] In addition, the battery 17 of the mobile terminal 11 is accommodated within the range of the first merged area 53. The first merged area 53 is located in an island shape in the central part surrounded by the first area S1, the second area S2, the third area S3, the fourth area S4, the fifth area S5, the sixth area S6, the tenth area S10, the eleventh area S11, the fifteenth area S15, the sixteenth area S16, the twentieth area S20, the twenty-first area S21, the twenty-second area S22, the twenty-third area S23, the twenty-fourth area S24, and the twenty-fifth area S25 along the outer peripheral surface of the main body 13. Furthermore, the battery 17 is located within the range of the thirteenth area S13 whose center is the center of the first merged area 53.

[0043] As a result, the center of gravity of battery 17, which has a relatively large mass, is located on the back surface close to the center of gravity of main body 13 excluding battery 17. Therefore, when mobile terminal 11 is held vertically or horizontally, 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 sections. 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 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 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, rear camera 15 arranged in, for example, the fifth area S5 on the rear side is located on the upper left rear side of 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 oriented vertically, rear camera 15 arranged in fifth region S5 on the back side is located on the upper right rear side 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, that is, the upper left rear side of display 21.

[0048] 9 is defined as the top side, rear camera 15 arranged in fifth region S5 on the back side is located on the upper right rear side of horizontally oriented display 21. The position of rear camera 15 is the opposite side to the position of rear camera 15 in horizontally oriented main body 13 with the long side defined as the top side shown in FIG.

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

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

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

[0052] When mobile terminal 11 in which a matrix area is defined in landscape orientation is oriented horizontally, rear camera 15 is disposed on the upper left rear side of display 21 when viewed from the front, while in landscape orientation. When mobile terminal 11 in which a matrix area is defined in landscape orientation is oriented vertically, rear camera 15 is disposed on the upper right rear side of display 21 when viewed from the front, while in portrait orientation.

[0053] The mobile terminal 11 may further include a circuit board 57. The circuit board 57 may be disposed 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 along 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. In terms of the matrix region, the circuit board 57 is arranged in a rectangular frame 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, so that the thickness of the battery when attached can be suppressed from increasing compared to the case where these are stacked. Furthermore, the battery 17, which has a relatively large mass, can be fixed reliably 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, the circuit board 57 has a hole 61. The battery 17 is inserted and arranged in this hole 61. Since the battery 17 is arranged in the center of the back surface, the hole 61 is also formed in the center of the back surface. That is, the circuit board 57 is formed in a ring shape having a rectangular hole 61 in the center of the back surface. This ring-shaped circuit board 57 is arranged at high density without generating any wasted space, following the rectangular frame region 59. That is, the mobile terminal 11 realizes a compact size of the entire mobile terminal 11 by adopting a shape and arrangement that allows the battery 17 and the circuit board 57 to be arranged at high density three-dimensionally.

[0057] In addition, since the battery 17 can be disposed by penetrating the hole 61 of the circuit board 57, the thickness of the mobile terminal 11 is further prevented from increasing when the battery is attached. Since the battery 17, which is relatively thick, can be disposed by inserting it into the hole 61 of the circuit board 57, it is possible to reduce the thickness of the main body 13 to a value substantially equal to the thickness of the 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 provided detachably on the back surface of the main body 13. The pair of protrusions 45 are arranged parallel to a pair of parallel sides of the rectangular battery 17 stored on the back surface. The battery 17 may be a thin standard type and a large 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 the mobile terminal 11 on which the standard type battery 17 is attached, the pair of protrusions 45 protruding from the back surface can be used as finger hooks, improving the grip of the main body 13. In addition, on the back surface on which the large capacity type battery 17 is attached, the height of the battery 17 and the pair of protrusions 45 from the back surface are approximately the same. As a result, the large capacity type battery 17 has a smaller step from the back surface, which suppresses other members from directly colliding with the side surface of the battery.

[0060] Moreover, 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 a cover member that covers a connection terminal for a card reader such as a barcode reader or opens an option area.

[0061] Therefore, according to the mobile terminal 11 of this embodiment, regardless of whether the mobile terminal 11 is held vertically or horizontally, 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 come up with various modified or amended examples within the scope of the claims, and it is understood that these also naturally belong to the technical scope of the present disclosure. In addition, the components in the above embodiments may be arbitrarily combined within the scope of the invention.

[0063] For example, in the above embodiment, the upper cover 47 provided on the back surface of the main body 13 may be a protruding portion that protrudes beyond the battery 17. In this case, the protruding portion as the upper cover 47 may be provided so as to be removable. On the back surface on which the standard type battery 17 is attached, the protruding portion as the upper cover 47 protrudes beyond the battery 17. Therefore, in the mobile terminal 11 on which the standard type battery 17 is attached, the protruding portion as the upper cover 47 protruding on the back surface can be used as a finger hook, and the grip of the main body 13 can be improved. In addition, on the back surface on which the large-capacity type battery 17 is attached, the height of the battery 17 and the protruding portion as the upper cover 47 from the back surface may be approximately the same. As a result, the step from the back surface of the large-capacity type battery 17 is reduced, and direct collision of other members with the side surface of the battery is suppressed.

[0064] In the above embodiment, a card reader or the like can be connected to the option area on the back of the main body 13, but this is not limited thereto. The option area may be capable of connecting electronic devices other than a card reader. The 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. The 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. The top cover 47 and the pair of protrusions 45 may not be attached so that various functional components and option areas can be freely exposed, but an option (electronic devices such as the above-mentioned card reader, connector, etc.) may be directly attached to the top cover 47 and the pair of protrusions 45, or an option may be attached to the position 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 electronic device itself as an option becomes a protrusion installed on the back of the main body 13.

[0065] An example of installing an option on the back of the main body 13 will be described. FIG. 10 is a diagram showing a first example of installing an option on the main body 13. In FIG. 10, a barcode reader 111 is attached to the top cover 47. FIG. 11 is a diagram showing a second example of installing an option on the main body 13. In FIG. 11, a barcode reader 111 is attached to one of a pair of protrusions 45. FIG. 12 is a diagram showing a third example of installing an option on the main body 13. In FIG. 12, a 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 showing a fourth example of installing an option on the main body 13. In FIG. 13, a 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 showing a fifth example of installing an option on the main body 13. In Fig. 14, a barcode reader 111 is attached to the position of 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 installation example of an option on the main body 13. In Fig. 15, a barcode reader 111 is attached to the position of the top cover 47, and a LAN connector 119 is attached to one of the pair of protrusions 45. The combinations of electronic devices installed in the positions of 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 (e.g., top cover 47 or an option) may be provided along a side of battery 17 on the upper side of main body 13, which is a side extending substantially left and right on the back surface of main body 13, in other words, a side substantially perpendicular to a pair of parallel sides extending substantially vertically on the left and right. This allows mobile terminal 11 to perform payment processing and extension of wired communication using various optional electronic devices, and provides a finger hook when mobile terminal 11 is held vertically, for example.

[0067] The same applies to a first protrusion (e.g., 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 use various optional electronic devices to perform payment processing and extend wired communication, and can provide a finger hook when mobile terminal 11 is held horizontally, for example.

[0068] Moreover, the second protrusion may be provided detachably from the main body 13. This allows the portable terminal 11 to dispense with the optional protrusion when payment processing or expansion of wired communication using USB or LAN is not required. Also, when the portable terminal 11 is rarely held vertically, the top cover 47 does not need to be a protrusion. This allows the addition of various functions to the portable terminal 11 and the weight reduction of the portable terminal 11 to be achieved at the same time. [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.
