=== First Embodiment ===
<Overall configuration of mobile phone 100>
Hereinafter, a first embodiment of the portable information display device will be described. The following description will be made by taking the cellular phone 100 as an example. Here, FIG. 1 is a diagram illustrating the overall configuration of the mobile phone 100 according to the first embodiment. FIG. 2 is a perspective view of the mobile phone 100. FIG. 3A is an enlarged view for explaining the rotation of the operation main body 120 with respect to the connecting member 130. FIG. 3B is an enlarged view illustrating movement of the connecting member 130 in the folding direction. FIG. 3C is an enlarged view for explaining a contact state of the buffer members 114 and 124 in a state where the display main body 110 and the operation main body 120 are folded. FIG. 4A is a diagram for explaining the appearance of a mobile phone having an inverted L shape. FIG. 4B is a diagram for explaining the appearance of the mobile phones in a side-by-side state.

  The mobile phone 100 includes a display main body 110 provided with a liquid crystal display 111 as a display unit, an operation main body 120 provided with operation buttons 121 as an operation unit, and the display main body 110 and the operation main body 120. And a connecting member 130 for connecting the two in a foldable manner.

  The display main body 110 has a thin box-like appearance. That is, the thickness of the display main body 110 is determined to be sufficiently thinner than the length and width of the display main body 110. In the display main body 110, the display surface 112 on which the liquid crystal display 111 is provided is a substantially rectangular plane in which four corners are chamfered in an arc shape. The display surface 112 has a pair of short sides (lateral edges in the state of FIG. 1) and a pair of long sides (vertical edges in the state of FIG. 1). In the state shown in FIG. 1, the display surface 112 is oriented vertically. The liquid crystal display 111 has a substantially rectangular screen (display area) whose screen is slightly smaller than the display surface 112. The orientation of this screen is aligned with the orientation of the display surface 112. Therefore, in the state of FIG. 1, the screen of the liquid crystal display 111 is also vertically long. In addition, a speaker 113 is provided on the display surface 112. In the illustrated mobile phone 100, the speaker 113 is provided in the vicinity of the short side opposite to the connecting member 130 and substantially in the middle in the length direction of the short side. The outer surface 115 of the display main body 110 located on the opposite side to the display surface 112 is a substantially rectangular plane similar to the display surface 112. On the outer surface 115, for example, a logo mark indicating a company name and a sub display are provided.

  In the display main body 110, the side surface formed between the display surface 112 and the outer surface is a pair of short side planes 116 formed between the short side of the display surface 112 and the short side of the outer surface 115. And a pair of long side planes 117 formed between the long side of the display surface 112 and the long side of the outer surface 115, and a curved surface 118 formed corresponding to the four corners. . In other words, the short side plane 116, the long side plane 117, and the curved surface 118 intersect the display surface 112 and the outer surface 115 at curved edges corresponding to the short side, the long side, and the corner portion. ing.

  As will be described later, in the present embodiment, one corner portion of the display main body 110 (the corner portion located at the lower left in FIG. 1) is attached to the connecting member 130. The display main body 110 can rotate approximately 90 degrees along the display surface 112 with respect to the connecting member 130. Further, the operation main body 120 is similarly attached to the connecting member 130.

  For this reason, the display main body 110 can have the two side surfaces opposed to the operation main body 120. For example, in the state of FIG. 1, the short side plane 116 located on the connecting member 130 side faces the operation main body 120. For convenience, in the following description, the short side plane 116 is referred to as a short side facing plane 116a (corresponding to the first display side facing plane). In the state of FIG. 4B, the long side plane 117 located on the connecting member 130 side faces the operation main body 120. For convenience, in the following description, the long side plane 117 is referred to as a long side facing plane 117a (corresponding to a second display side facing plane). Of these opposed planes, the short-side opposed plane 116a intersects the display surface 112 at one side (side on the display surface side). The long side facing flat surface 117a intersects the display surface 112 on one side and is formed in a direction intersecting with the short side facing flat surface 116a (orthogonal direction in this example).

  Similarly to the display main body 110, the operation main body 120 also has a thin box-like appearance. Therefore, in this operation main body 120, the operation surface 122 on which the operation buttons 121 are provided is also a substantially rectangular plane in which four corners are chamfered in an arc shape. In addition to the operation buttons 121, a microphone 123 is provided on the operation surface 122. The microphone 123 is provided in the vicinity of the short side opposite to the connecting member 130 and substantially in the middle in the length direction of the short side. Further, the outer surface 125 of the operation main body 120 located on the side opposite to the operation surface 122 is also a substantially rectangular plane. Therefore, the side surface of the operation main body 120 includes a pair of short side planes 126 formed between the short sides, a pair of long side planes 127 formed between the long sides, and four corners. The curved surface 128 is formed corresponding to the corner.

  In addition, one corner of the operation main body 120 is also attached to the connecting member 130. Further, the operation main body 120 can rotate approximately 90 degrees along the operation surface 122 with respect to the connecting member 130. Therefore, the operation main body 120 can also face the display main body 110 on the two side surfaces. For example, in the state of FIG. 1, the short side facing plane 126 a (corresponding to the first operation side facing plane) located on the connecting member 130 side faces the display main body 110. 4B, the long side facing plane 127a (corresponding to the second operation side facing plane) located on the coupling member 130 side faces the display main body 110. Among these opposed planes, the short side opposed plane 126a intersects the operation surface 122 at one side (side on the operation surface 122 side). Further, the long side facing plane 127a is formed in a direction that intersects with the operation surface 122 at one side thereof and intersects with the short side facing plane 126a (orthogonal direction in this example).

  Each of the display main body 110 and the operation main body 120 is provided with a buffer member. The buffer member 114 on the display body 110 side corresponds to a display-side protection member. In the present embodiment, the buffer member 114 is made of thin resin having elasticity, and is formed in a rectangular shape. The buffer member 114 is provided such that a part thereof is located on the long side plane 117 and the other part is located on the display surface 112. Specifically, the buffer member 114 on the display main body 110 side is provided one by one on the pair of long side planes 117. Further, the buffer member 114 is provided at a position farther from the connecting member 130 in the long side direction.

  On the other hand, the buffer member 124 on the operation main body 120 side corresponds to an operation-side protection member. In the present embodiment, the buffer member 124 has the same configuration as the buffer member 114 on the display body 110 side. That is, the buffer member 124 is also made of resin and has a thin rectangular shape. The buffer member 124 is also provided at the same position as the buffer member 114 on the display body 110 side. In other words, the buffer member 124 on the operation main body 120 side is provided at a position where it can contact the buffer member 114 on the display main body 110 side. Specifically, the distance from a virtual line L1 (described later) passing through the folding center of the connecting member 130 is equalized between the buffer member 114 on the side and the buffer member 124 on the operation main body 120 side.

  Therefore, the buffer member 114 on the display main body 110 side and the buffer member 124 on the operation main body 120 side close the display main body 110 and the operation main body 120, that is, as shown in FIG. The display surface 112 and the operation surface 122 are in direct contact with each other in a face-to-face state, thereby preventing a problem that the display surface 112 and the operation surface 122 are in direct contact with each other. Further, the buffer member 114 on the display main body 110 side and the buffer member 124 on the operation main body 120 side are in contact with each other even when the display main body 110 and the operation main body 120 are opened in a main shape (state in FIG. 4B, which will be described later). The problem that the opposed flat surfaces that are in contact with each other directly come into contact with each other is prevented.

  In the present embodiment, the shapes, for example, thicknesses of the buffer members 114 and 124 are determined in consideration of the state in which the display main body 110 and the operation main body 120 are opened in a main shape. That is, the shape of these buffer members 114 and 124 is such that the edges that intersect the display surface 112 on the display side facing plane (the short side facing plane 116a and the long side facing plane 117a) and The edges intersecting with the operation surface 122 in the opposing plane (the short side opposing plane 126a and the long side opposing plane 127a) are determined to be parallel to each other. As described above, since the function of positioning the display main body 110 and the operation main body 120 is also provided to the buffer members 114 and 124, the configuration can be simplified.

<About the connecting member 130>
The connecting member 130 has a display side mounting portion 131 as a first mounting portion and an operation side mounting portion 132 as a second mounting portion. The operation side attachment portion 132 is foldably connected to the display side attachment portion 131. Specifically, the display side attachment portion 131 and the operation side attachment portion 132 are connected to each other by a hinge portion 133 so as to be foldable. At this time, the display side attachment portion 131 and the operation side attachment portion 132 rotate about the rotation center RC1 of the hinge portion 133 as shown in an enlarged view in FIG. 3B. That is, the rotation center RC1 of the hinge part 133 corresponds to the folding center of the display side attachment part 131 and the operation side attachment part 132.

  The display main body 110 is attached to the display-side attachment portion 131 so as to be rotatable along the display surface 112. Specifically, the display side attaching portion 131 is attached to a corner portion sandwiched between the long side facing flat surface 117a and the short side facing surface 116a of the display main body 110. Then, as shown in an enlarged view in FIG. 3A, the display main body 110 has a virtual line L1 passing through the rotation center RC1 of the hinge part 133 (in a virtual line L1 passing through the folding center of the first mounting part and the second mounting part). It is mounted in a rotatable state within a range not exceeding. In this embodiment, the display main body 110 is attached so as to be able to rotate within a range of about 90 degrees as indicated by an arrow A in FIG. Similarly, the operation main body 120 is attached to the operation side attachment portion 132 in a state where it can rotate along the operation surface 122. That is, the operation-side attachment portion 132 is attached to a corner portion sandwiched between the long-side facing flat surface 127a and the short-side facing flat surface 126a of the operation main body 120, and an imaginary line L1 passing through the rotation center RC1 of the hinge portion 133. As shown by the arrow B in the figure, specifically, it is rotatably attached within a range of 90 degrees. As described above, the connecting member 130 of this embodiment is attached to the corner portion of the display main body 110 and the corner portion of the operation main body 120. With this configuration, the connecting member 130 can be made small. Thereby, size reduction of an apparatus can be achieved.

<About the state change of the display main body 110 and the operation main body 120>
Then, as shown in FIG. 1, the display side attachment portion 131 and the operation side attachment portion 132 are opened, and the display body 110 is directed upward and the operation body 120 is directed downward. From this state, when the display body 110 is rotated clockwise and the operation body 120 is rotated counterclockwise to the end of the rotatable range, the short side facing plane 116a (first display side facing plane) of the display body 110 is obtained. And the short side facing plane 126a (first operation side facing plane) of the operation main body 120 face each other. In this state, the display surface 112 of the display main body 110 and the operation surface 122 of the operation main body 120 are aligned in a predetermined direction. Specifically, they are arranged in the vertical direction (long side direction). For convenience, in the following description, this state is also referred to as a vertical state (or simply “vertical state”) of the mobile phone 100. The vertical state of the mobile phone 100 is suitable for making a call, for example. That is, in this vertical state, when the speaker 113 is put on the ear, the microphone 123 is positioned at the mouth. For this reason, the microphone 123 can receive the user's voice with high sensitivity.

  When the display main body 110 is rotated counterclockwise and the operation main body 120 is rotated clockwise from this vertical state, the mobile phone 100 can be formed into a real shape. That is, when the display body 110 is rotated 90 degrees counterclockwise, that is, when the display body 110 is rotated to the end of the other rotatable range, the display body 110 rotates 90 degrees with respect to the display body 110 as shown in FIG. 4A. It becomes an inverted L-shape. Further, when the operation main body 120 is rotated 90 degrees clockwise (when the operation main body 120 is rotated to the end of the other rotatable range), the long-side facing flat surface 127a of the display main body 110 is changed to the operation main body 120 as shown in FIG. It faces the long side facing flat 127a and becomes a main shape. At this time, the display surface 112 of the display main body 110 is arranged in a lateral direction (corresponding to a direction intersecting the predetermined direction) with respect to the operation surface 122 of the operation main body 120. This state of being arranged in the horizontal direction (also referred to as a side-by-side state for convenience) is suitable for displaying information (content) such as e-mail on the liquid crystal display 111, for example.

  For example, when it is difficult to see the screen of the liquid crystal display 111 due to light reflection or the like, the display main body 110 and the operation main body 120 are rotated around the hinge part 133, and the angle formed by the two is changed, thereby reflecting the light. Can be prevented. Further, in this side-by-side state, the screen is easy to see even if the operation main body 120 is held with either the right hand or the left hand. Furthermore, you may hold with both hands like a paperback book. For this reason, the usability of the mobile phone 100 can be improved.

  Thus, in the mobile phone 100 of the present embodiment, the display main body 110 can be rotated along the display surface 112 and the operation main body 120 can be rotated along the operation surface 122. Thereby, the rotatable range of the display main body 110 with respect to the operation main body 120 can be expanded more than before. Specifically, it can be rotated approximately 180 degrees. As a result, regarding the orientation of the liquid crystal display 111, the range of selection can be expanded, and information can be easily read and the usability can be improved. Further, in this cellular phone, switching between the vertical state and the horizontal state can be realized by rotating both the display main body 110 and the operation main body 120 to the end of the rotatable range. That is, the end of the rotatable range is the position reference for the display main body 110 and the operation main body 120. For this reason, by rotating to the end of the rotatable range, the display main body 110 and the operation main body 120 can be positioned in a desired relationship, and usability can be improved. Since the rotatable range of the display main body 110 and the operation main body 120 is set within a range not exceeding the virtual line L1 passing through the folding center of the connecting member 130, the collision between the display main body 110 and the operation main body 120 is prevented. be able to.

  In the present embodiment, as shown in FIGS. 3A and 3B, the rotation center RC2 with respect to the display-side mounting portion 131 of the display body 110 and the rotation center RC3 with respect to the operation-side mounting portion 132 of the operation body 120 are related to these. The positions are determined so as to coincide with each other when the display side mounting portion 131 and the operation side mounting portion 132 are folded. With this configuration, the connecting member 130 can be rotated even when the display main body 110 and the operation main body 120 are closed (the connecting member 130 is folded). Accordingly, it is possible to select a direction in which the display main body 110 and the operation main body 120 are opened while the display main body 110 and the operation main body 120 are closed. For example, a vertical opening and a horizontal opening can be selected. Thereby, the usability can be further improved.

<Setting of display direction of liquid crystal display 111>
Next, the electrical configuration of the mobile phone 100 will be described. Here, FIG. 5A is a block diagram for explaining the electrical configuration of the mobile phone 100. FIG. 5B is a schematic diagram for explaining the operation-side angle detection unit 142 and illustrates a state in which the magnet 142a and the magnetic sensor 142b are close to each other. FIG. 5C is a schematic diagram for explaining the operation-side angle detection unit 142 and illustrates a state in which the magnet 142a and the magnetic sensor 142b are separated from each other.

  As illustrated in FIG. 5A, the mobile phone 100 includes a liquid crystal display 111, a display side angle detection unit 141, an operation button 121, an operation side angle detection unit 142, and a controller 140. Each of the liquid crystal display 111, the display-side angle detection unit 141, the operation button 121, and the operation-side angle detection unit 142 is electrically connected to the controller 140.

  Among these units, the display-side angle detection unit 141 detects the rotation angle of the display main body 110 with respect to the display-side attachment unit 131, and corresponds to a first rotation angle detection unit. The operation side angle detection unit 142 detects a rotation angle of the operation main body 120 with respect to the operation side attachment unit 132, and corresponds to a second rotation angle detection unit. The controller 140 is a control unit that controls the mobile phone 100, and includes a CPU, a memory, and the like (not shown), and operates according to a program stored in the memory. The controller 140 corresponds to a display direction setting unit, and sets the display direction of information on the liquid crystal display 111 based on the detection result by the display side angle detection unit 141 and the detection result by the operation side angle detection unit 142.

  The display side angle detection unit 141 and the operation side angle detection unit 142 are different in location and detection target, but have the same configuration. Therefore, the configuration of the operation side angle detection unit 142 will be described, and the description of the display side angle detection unit 141 will be omitted. The operation side angle detection unit 142 includes a magnet 142a and a magnetic sensor 142b. The magnet 142a is provided, for example, in the operation side mounting portion 132, and the magnetic sensor 142b is provided, for example, in the operation main body 120. The arrangement interval of these magnets 142a and magnetic sensor 142b is determined according to the rotation angle of the operation main body 120 with respect to the operation side mounting portion 132. In this example, as shown in FIG. 5B, the magnet 142a is closest to the magnetic sensor 142b when the operation side mounting portion 132 is rotated so that the virtual line L1 is parallel to the short side of the operation main body 120. . Further, as shown in FIG. 5C, the magnet 142a is farthest from the magnetic sensor 142b in a state where the operation side mounting portion 132 is rotated so that the virtual line L1 is parallel to the long side of the operation main body 120. The arrangement interval between the magnet 142 a and the magnetic sensor 142 b changes according to the rotation angle of the operation main body 120 with respect to the operation side mounting portion 132. For this reason, the controller 140 can recognize the rotation angle of the operation main body 120 with respect to the operation side mounting portion 132 based on the strength of the detection signal output from the magnetic sensor 142b, that is, the detection result.

  The controller 140 (display direction setting unit) can recognize the rotation states of the display main body 110 and the operation main body 120 based on the detection results by the display side angle detection unit 141 and the operation side angle detection unit 142. Then, the controller 140 sets the direction of information such as characters and images displayed on the liquid crystal display 111 based on the recognized rotation state. For example, in the case of the vertical state shown in FIG. 1, the direction of the displayed information is set so that the speaker 113 side is up and the connecting member 130 side is down. On the other hand, in the side-by-side state shown in FIG. 4B, the orientation of the information to be displayed is set so that the connecting member 130 side is up and the speaker 113 side is down. Further, in the inverted L-shaped state shown in FIG. 4A, the direction of the displayed information is set so that the speaker 113 side is on the left and the connecting member 130 side is on the right. With this configuration, information is displayed in a direction suitable for the rotation state of the display main body 110 and the operation main body 120. As a result, the usability can be further improved.

=== Second Embodiment ===
In the first embodiment described above, the connecting member 130 is attached to the corner portion of the display main body 110 and the corner portion of the operation main body 120. Therefore, it is required to change the attachment position of the connecting member 130 between the right-handed mobile phone 100 that operates the operation button 121 with the right hand and the left-handed mobile phone 100 that operates the operation button 121 with the left hand. . That is, the mobile phone 100 for right-hand operation is configured such that the operation main body 120 is positioned on the right side of the display main body 110 in a state where the display main body 110 and the operation main body 120 are arranged side by side. On the contrary, the mobile phone 100 for left-hand operation is configured such that the operation main body 120 is located on the left side of the display main body 110 in this side-by-side state. However, it is not preferable to manufacture the mobile phone 100 for the right hand operation and the mobile phone 100 for the left hand operation as separate parts because the manufacturing cost increases.

  Hereinafter, a second embodiment in consideration of this point will be described. Here, FIG. 6A is a diagram illustrating the configuration of the second embodiment. FIG. 6B is a diagram illustrating the mobile phone 100 for left-hand operation.

  In the cellular phone 100, the display main body 110 includes a display unit 110a provided with a liquid crystal display 111 as a display unit, and a display side on which the display unit 110a is mounted and attached to the display side mounting unit 131 of the connecting member 130. Attached unit 110b. Further, the operation main body 120 includes an operation unit unit 120a provided with an operation button 121 as an operation unit, and an operation side mounted unit to which the operation unit unit 120a is mounted and attached to the operation side mounting unit 132 of the connecting member 130. 120b.

  The electrical connection between the display unit 110a and the mounted unit 110b on the display side is performed by a pin plug and a pin jack. In this example, a pin plug 110c is provided on the display unit 110a, and a pin jack 110d is provided on the display-side mounted unit 110b. The display unit 110a is electrically connected to the display-side mounted unit 110b by inserting the pin plug 110c into the pin jack 110d. In addition, the electrical connection between the operation unit 120a and the operation-side mounted unit 120b is also performed by a pin plug and a pin jack. That is, a pin plug 120c is provided on the operation unit 120a, and a pin jack 120d is provided on the operation-side mounted unit 120b. In this case, transmission / reception of information is performed by a serial signal.

  Here, in this embodiment, the external appearance of the display unit 110a and the operation unit 120a is set to the same shape. In addition, the shape and position of the pin plug are also set to be the same in the display unit 110a and the operation unit 120a. Further, regarding the mounted unit 110b on the display side and the mounted unit 120b on the operation side, there is a difference that the corners attached to the connecting member 130 are set at symmetrical positions, but for other shapes , Common to both units. Therefore, the pin jack shape and position are also determined in the same way.

  This is because the display unit 110a and the operation unit 120a are configured to be interchangeable. In other words, with this configuration, the display unit 110a can be mounted on the operation-side mounted unit 120b, and the operation unit 120a can be mounted on the display-side mounted unit 110b. As a result, as shown in FIG. 6B, a configuration in which the operation unit 120a is positioned on the left side of the display unit 110a in a side-by-side state can be realized. In this configuration, since the operation unit 120a is located on the left side of the display unit 110a, the operation button 121 can be easily operated with the left hand. That is, the specification is suitable for left-hand operation. The display unit 110a and the operation unit 120a are exchanged by the user. In this case, it is possible to select a desired specification that is easy for the user to use, so that convenience can be improved.

  Note that whether the display unit 110a or the operation unit 120a is attached to the display-side attached unit 110b or the operation-side attached unit 120b may be determined when the mobile phone 100 is manufactured. That is, the display unit 110a and the operation unit 120a may be selected and joined to the display-side mounted unit 110b and the operation-side mounted unit 120b. In this case, although the specification cannot be changed by the user himself, the mobile phone 100 having different specifications can be manufactured using common parts. As a result, the number of parts can be reduced, and as a result, the cost of the apparatus can be reduced.

=== Third Embodiment ===
By the way, the second embodiment described above has a configuration in which the display unit 110a and the operation unit 120e are replaced when the specifications of the mobile phone 100 are changed. However, it is not limited to this configuration. For example, the display unit 110e and the operation unit 120e may be reversed.

  Hereinafter, the third embodiment configured as described above will be described. Here, FIG. 7A is a diagram illustrating the configuration of the third embodiment. FIG. 7B is a diagram illustrating a state suitable for right-hand operation by inverting the display unit 110e and the operation unit 120e.

  In the cellular phone 100, the display main body 110 includes a display unit 110e provided with a liquid crystal display 111 as a display unit, and a display-side base unit 110f having a display-side rotation shaft 110g. On the other hand, the operation main body 120 includes an operation unit unit 120e provided with an operation button 121 as an operation unit, and an operation-side base unit 120f having an operation-side rotation shaft 120g. The display unit 110e is rotatably attached to the display-side base unit 110f by the display-side rotation shaft 110g. The operation unit 120e is rotatably attached to the operation-side base unit 120f by the operation-side rotation shaft 120g.

  Here, the rotation direction of the display unit 110e is determined to be different from the folding direction of the connecting member 130 and the rotation direction of the display body 110 with respect to the display-side mounting portion 131. For example, the direction of the display-side rotation shaft 110g is determined to be orthogonal to the folding center line of the connecting member 130 and also to the rotation axis with respect to the display-side mounting portion 131 of the display body 110. Similarly, the rotation direction of the operation unit unit 120e is also determined in a direction different from the folding direction of the connecting member 130 and the rotation direction of the operation main body 120 with respect to the operation side attachment portion 132. For example, the direction of the operation-side rotation shaft 120g is determined to be perpendicular to the folding center line of the connecting member 130 and also to the rotation axis with respect to the operation-side attachment portion 132 of the operation body 120.

  If comprised in this way, the specification of the mobile telephone 100 can be changed by rotating the display part unit 110e and the operation part unit 120e centering on a corresponding rotating shaft. For example, the state illustrated in FIG. 7A is a side-by-side state, and the operation unit 120e is located on the left side of the display unit 110e. For this reason, it is in a state suitable for left hand operation. Then, from this state, when the display unit 110e is inverted (rotated 180 degrees) about the display-side rotation shaft 110g and the operation unit unit 120e is inverted about the operation-side rotation shaft 120g, FIG. It becomes the state of. 7B is a state as viewed from the outer surface 115 of the operation unit unit 120e and the outer surface 115 of the display unit unit 110e. Therefore, when viewed from the display surface 112 and the operation surface 122, the operation unit unit 120e. Is located on the right side of the display unit 110e. Therefore, it is in a state suitable for right hand operation. As described above, in the third embodiment, the specification can be easily changed by reversing the operation unit 120e and the display unit 110e.

  In addition, the liquid crystal display 111 and the operation buttons 121 can be directed to the outside of the mobile phone 100 with the connecting member 130 folded. As a result, the usability can be further improved.

=== Fourth Embodiment ===
Incidentally, in each of the above-described embodiments, each of the display main body 110 and the operation main body 120 is configured to be able to rotate approximately 90 degrees with respect to the connecting member 130. In this regard, each of the display main body 110 and the operation main body 120 can be configured to be rotatable by approximately 180 degrees with respect to the connecting member 130.

  Hereinafter, the fourth embodiment configured as above will be described. Here, FIG. 8 is a diagram for explaining the fourth embodiment. FIG. 9A is a diagram illustrating a state in which the display main body 110 is rotated 45 degrees counterclockwise with respect to the connecting member 130 and the operation main body 120 is rotated clockwise with respect to the connecting member 130. FIG. 9B is a diagram for explaining a state in which the display main body 110 and the operation main body 120 are rotated side by side from the state of FIG. 9A. FIG. 10A is a diagram for explaining a state in which the display main body 110 is rotated 45 degrees clockwise with respect to the connecting member 130 and the operation main body 120 is rotated 45 degrees counterclockwise with respect to the connecting member 130. FIG. 10B is a diagram for explaining a state in which the display main body 110 and the operation main body 120 are further rotated side by side from the state of FIG. 10A.

  The mobile phone 100 is also composed of a display main body 110, an operation main body 120, and a connecting member 130. The cellular phone 100 differs from the cellular phone 100 of each of the embodiments described above in that the range of rotation of the display body 110 relative to the coupling member 130 (display-side mounting portion 131) and the coupling member 130 (operation of the operation body 120) It is in a rotatable range with respect to the side attachment portion 132). That is, there is a significant difference in configuration in that each rotatable range is approximately 180 degrees.

  Accordingly, the display surface 112 of the display main body 110 has a shape in which a rectangle and a semicircle are combined. For this reason, the side of the display main body 110 has a curved surface 119 on the connecting member 130 side. In addition, a first long side facing plane 117b (corresponding to a first display side facing plane) is formed on one side of the curved surface 119, and a second long side is formed on the other side of the curved surface 119. A side facing plane 117c (corresponding to a second display side facing plane) is formed. Furthermore, a short side plane 116 and a curved surface 118 are provided between the end of the first long side facing plane 127a and the end of the second long side facing plane 127a, which are opposite to the curved surface 119. It has been. The first long side facing plane 117b and the second long side facing plane 117c intersect with the display surface 112 of the display main body 110, respectively. Further, the first long side facing plane 117b and the second long side facing plane 117c are provided in parallel to each other.

  Similarly, with respect to the operation main body 120, the operation surface 122 has a shape in which a rectangle and a semicircle are combined. For this reason, the side surface of the operation main body 120 includes a curved surface 129 corresponding to the portion on the connecting member 130 side, and a first long side facing plane 127b (first operating side facing) formed on one side of the curved surface 129. The second long side facing plane 127c (corresponding to the second operation side facing plane) formed on the other side of the curved surface 128, and the curved surface 129 on the opposite side. The short side plane 126 and the curved surface 128 are formed. The first long side facing plane 127b and the second long side facing plane 127c intersect with the display surface 112 of the display main body 110, respectively. Further, the first long side facing plane 127b and the second long side facing plane 127c are provided in parallel to each other.

  In the cellular phone 100, as described above, the rotatable range of the display main body 110 with respect to the display side mounting portion 131 is approximately 180 degrees, and the rotatable range of the operation main body 120 with respect to the operation side mounting portion 132 is also approximately 180 degrees. . In other words, the rotatable range with respect to each attachment portion of the display main body 110 and the operation main body 120 is set to a range that does not exceed the imaginary line L1 passing through the folding center of the connecting member 130. Also in this cellular phone 100, the display main body 110 and the operation main body 120 can be changed to different specifications by rotating with respect to the connecting member 130. For example, when the display main body 110 is rotated counterclockwise and the operation main body 120 is rotated clockwise from the vertically aligned state illustrated in FIG. 8, the horizontal aligned state illustrated in FIG. 9B is obtained via the inverted L-shaped state illustrated in FIG. 9A. . 9B, the first long-side facing plane 117b of the display body 110 and the first long-side facing plane 127b of the operation body 120 face each other, and the operation body 120 is positioned on the right side of the display body 110. Is positioned. For this reason, it becomes a specification suitable for right-handed operation. On the other hand, when the display main body 110 is rotated clockwise and the operation main body 120 is rotated counterclockwise from the vertically aligned state shown in FIG. 8, the horizontal L side state shown in FIG. . In the side-by-side state shown in FIG. 10B, the second long side facing plane 117 c of the display body 110 and the second long side facing plane 127 c of the operation body 120 face each other, and the operation body 120 is placed on the left side of the display body 110. Is positioned. For this reason, it becomes a specification suitable for left-handed operation.

  9B is compared with the state of FIG. 10B, in the state of FIG. 9B, the display surface 112 of the display main body 110 and the operation surface 122 of the operation main body 120 are along the horizontal direction (short side direction). They are arranged in the order of left and right. On the other hand, in the state of FIG. 10B, the display surface 112 of the display main body 110 and the operation surface 122 of the operation main body 120 are arranged in the reverse order of FIG. 9B. That is, the operation surface 122 of the operation main body 120 and the display surface 112 of the display main body 110 are arranged in the order of the left side and the right side along the horizontal direction. By adopting such a configuration, the specification of the mobile phone 100 can be changed by a rotation operation with respect to the attachment portion of the display main body 110 or the operation main body 120. As a result, the usability can be further improved.

  Further, even in this embodiment, when the display main body 110 and the operation main body 120 are rotated to the end of the rotatable range, corresponding opposing side surfaces are configured to face each other. For example, in the state of FIG. 9B, the first long-side facing plane 117b of the display body 110 and the first long-side facing plane 127b of the operation body 120 face each other. On the other hand, in the state of FIG. 10B, the second long side facing plane 117c of the display body 110 and the second long side facing plane 127c of the operation body 120 face each other. For this reason, rotation operation of the display main body 110 and the operation main body 120 can be made easy. That is, the display main body 110 and the operation main body 120 can be positioned in a desired relationship by rotating to the end of the rotatable range. As a result, usability can be improved.
