Description

  The present invention relates to a foldable mobile terminal device that includes two rotation shafts and that can be opened and closed in a longitudinal direction and a short side direction, and particularly relates to a foldable mobile phone that can be opened and closed in a longitudinal direction and a short side direction.

  In a foldable mobile phone that can fold and store two cases, you can hold the first case with an operation unit such as a numeric keypad in your hand and look at the display on the second case. It is common. Therefore, the display unit is often used by extending in the longitudinal direction.

  Recently, however, mobile phones that receive and display television broadcasts have been put into practical use and are beginning to spread. In order to view a horizontally long television broadcast screen, it is easier to see the display unit rotated 90 degrees in the short direction. For this reason, a structure has been proposed in which the direction of the display unit is switched from the longitudinal direction to the transversal direction by mechanically rotating the second housing having the display unit (see, for example, Patent Document 1).

  An example of a conventional folding cellular phone is shown in FIGS. 16 to 18. A cellular phone 60 in FIG. 16 includes a first casing 61 having an operation unit 71, a second casing 62 having a display unit 72, and a hinge unit 63. And the hinge part 63 is supported by the 1st rotation axis | shaft 61a provided in the 1st housing | casing 61 so that rotation in the arrow A direction is possible, and the 2nd rotation axis | shaft 63a provided in the upper end of the hinge part 63 is surrounded. The second housing 62 having the display unit 72 is rotatably supported. For this reason, the mobile phone 60 is configured so that the second housing 62 is placed on the second rotating shaft of the hinge portion 63 in a state where the hinge portion 63 stands vertically with respect to the first housing 61 as shown in FIG. It can rotate in the direction of arrow B around 63a. In this state, when the second housing 62 is tilted together with the hinge portion 63 in the direction of arrow C, the mobile phone 60 opens the display portion 72 of the second housing 62 in the short direction as shown in FIG. Can be used.

  As described above, in the conventional mobile phone 60, in order to change the display unit 72 from the longitudinal direction to the short side state, as shown in FIGS. A three-stage rotation operation, that is, a rotation operation and a rotation operation of an arrow C, is performed. And the mechanical movement of the housing | casing by rotation operation is detected, and the display direction of the image displayed is switched in conjunction with the motion of a housing | casing.

  Here, as a modification of the conventional mobile phone 60, as shown in FIG. 19, if the second casing 62 is opened in the direction of the arrow D from the state of being overlaid on the first casing 61, It is convenient that the display unit 72 can be set in the short-side direction by the above operation. In this case, when the second casing 62 is opened from the folded state, it is properly determined whether the second casing 62 is opened in the longitudinal direction or the short direction, and the display direction of the display unit is correctly determined. It will be necessary.

  Also, some foldable mobile phones have a line connection control function that automatically connects the line when the case is opened when an incoming call is received and automatically disconnects the line when the case closes after the line is connected. The installed one has been put into practical use. According to this mobile phone, it is convenient because a phone call can be made immediately without pressing the call start button by simply opening the housing. Also, it is convenient because it can be ended simply by closing the case without pressing the call end button.

  When the mobile phone 60 is equipped with a line connection control function for automatically connecting or disconnecting a line according to the opening and closing of the casing, whether the second casing 62 is opened in the longitudinal direction or in the short direction It is important to correctly identify whether it has been opened. That is, when the line connection control function is installed in the conventional mobile phone 60, as shown in FIG. 16, if the mobile phone 60 is detected to be opened in the longitudinal direction and the line is connected, a call can be made without any problem.

However, as shown in FIG. 19, if the line is connected with the cellular phone 60 opened in the short direction, the microphone and speaker positions do not match the positional relationship between the human mouth and ears, so that a call can be made. Can not. When the second casing 62 is temporarily closed in the direction opposite to the arrow D in FIG. 19 and then reopened in the longitudinal direction as shown in FIG. 16, the second casing 62 is closed once. The line is disconnected. Therefore, when the second casing 62 is reopened in the longitudinal direction, it is no longer possible to talk.

To detect. For this reason, if it is the longitudinal opening / closing detection means that first detects that the second casing has been opened, it can be determined that the second casing has been opened in the longitudinal direction.

  According to the present invention, in the portable terminal device described above, wireless telephone communication means is further provided so that the line is connected when the longitudinal opening / closing detection means first detects that the second housing is opened at the time of incoming call. I have to. This makes it possible to connect the line when the second casing is first opened in the longitudinal direction at the time of an incoming call, but not to connect the line when it is first opened in the short direction.

  In addition, in the present invention, as the longitudinal direction opening / closing detection means and the short direction opening / closing detection means, a set of opening / closing detection means is configured with a magnet and a magnetic force detection means for detecting magnetic force such as a Hall element, the magnitude of the magnetic force, Depending on the sensitivity of the open / close detection means, the open / close state of the second casing is detected by the longitudinal open / close detection means and the short open / close detection means. Thereby, not only the positional relationship between the longitudinal direction opening / closing detection means and the short direction opening / closing detection means, but also the accuracy of opening / closing detection can be improved by utilizing the magnitude of the magnetic force of the magnet and the sensitivity of the opening / closing detection means.

(Embodiment 1)
In the first embodiment of the present invention, the arrangement of the longitudinal opening / closing detection means and the short direction opening / closing detection means for detecting that the second casing is opened with respect to the first casing is set to a predetermined condition, that is, When the second casing is opened, only one open / close detection means corresponding to the opening direction of the second casing detects that the second casing is opened, and the second casing is opened. The other open / close detection means that does not correspond to the other direction solves the problem on the condition that the second casing is not detected to be opened.

  FIG. 1 is a perspective view showing a state in which the second casing 2 of the foldable mobile phone 100 according to Embodiment 1 of the present invention is opened in the longitudinal direction. The first housing 1 with the operation unit 51 supports the first rotation shaft 9 with bearings 1a and 1b, and the hinge unit 3 rotates around the first rotation shaft 9 with the bearings 3a and 3b. It is attached movably. A second rotation shaft 10 indicated by a broken line is provided at one corner of the hinge portion 3 so as to be orthogonal to the first rotation shaft 9, and the second casing 2 is rotated on the second rotation shaft 10. It is attached freely.

  A display unit 52 is provided in the second housing 2. A magnet 4 and a magnet 6 a are embedded in the first housing 1. Further, the second casing 2 has the Hall element 5 at the position corresponding to the magnet 4 when it is folded on the first casing, and the Hall element is positioned at the position corresponding to the magnet 6a. 7 is embedded as a short direction opening / closing detection means.

  The Hall element 5 detects that the second casing 2 is opened in the longitudinal direction due to the loss of the magnetic force of the magnet 4 when the second casing 2 is opened and the magnet 4 is separated. Then, the second housing 2 closes and approaches the magnet 4, and when the magnetic force of the magnet 4 is detected, it is detected that the second housing 2 is closed in the longitudinal direction. As shown in FIG. 1, the Hall element 7 is located near the first rotating shaft 9, detects the magnetic force of the magnet 6a even when the second housing 2 is opened, and When the body 2 is closed, the magnet 6a is further approached and the magnetic force is continuously detected.

  Thus, in the foldable mobile phone 100, when the second casing 2 is opened and closed with respect to the first casing 1 in the longitudinal direction, only the Hall element 5 opens and closes in the longitudinal direction of the second casing 2. However, the Hall element 7 does not detect the opening / closing of the second casing 2 in the longitudinal direction.

  FIG. 2 is a perspective view showing a state in which the second casing 2 of the foldable mobile phone 100 according to Embodiment 1 of the present invention is opened in the lateral direction. The arrangement of each part is the same as that in FIG. 1, but the second casing 2 rotates around the second rotation shaft 10 from the closed state, so that the second casing 2 is the first casing. Open to the body 1 in the short direction.

  The Hall element 7 detects that the second casing 2 is opened in the short direction due to the loss of the magnetic force of the magnet 6a when the second casing 2 is opened and the magnet 6a is separated. Then, the second casing 2 closes and approaches the magnet 6a, and when the magnetic force of the magnet 6a is detected, it is detected that the second casing 2 is closed in the short direction. The Hall element 5 is located near the central axis of the second rotation shaft 10 and detects the magnetic force of the magnet 4 even when the second housing 2 is opened. When closed, the magnet 4 is further approached and the magnetic force is continuously detected.

  Thus, in the foldable mobile phone 100, when the second housing 2 is opened and closed with respect to the first housing 1 in the short direction, only the Hall element 7 is in the short direction of the second housing 2. However, the Hall element 5 does not detect the opening and closing of the second casing 2 in the short direction.

  FIG. 3 shows a side view when the second casing 2 of the foldable mobile phone 100 according to Embodiment 1 of the present invention is opened in the longitudinal direction. In the drawing, “R” schematically represents the distance that the magnetic force of the magnet 4 and the magnet 6a reaches, and the two-dot chain line circle schematically illustrates the range that the magnetic force of the magnet 4 and the magnet 6a extends.

  FIG. 3A shows a state where the second housing 2 is slightly opened in the longitudinal direction. At this point, the Hall element 5 detects that the second casing 2 has opened in the longitudinal direction due to the opening of the second casing 2 and the loss of the magnetic force of the magnet 4. On the other hand, the Hall element 7 is located near the first rotation shaft 9 and detects the magnetic force of the magnet 6a. FIG. 3B shows a state in which the second housing 2 is greatly opened in the longitudinal direction. In the state of FIG. 3B, the magnetic force of the magnet 4 does not reach the Hall element 5, and it is still detected that the second casing 2 is opened in the longitudinal direction. On the other hand, the Hall element 7 continues to detect the magnetic force of the magnet 6a.

  FIG. 4 shows a front view when the second casing 2 of the foldable mobile phone 100 according to Embodiment 1 of the present invention is opened in the lateral direction. As in FIG. 3, “R” in the figure indicates the distance covered by the magnet 4 and the magnet 6 a, and the two-dot chain circle indicates the range covered by the magnet 4 and the magnet 6 a.

  FIG. 4A shows a state in which the second housing 2 is closed. FIG. 4B shows a state where the second housing 2 is slightly opened in the short direction. At this point, the Hall element 7 detects that the second casing 2 is opened in the short direction due to the opening of the second casing 2 and the loss of the magnetic force of the magnet 6a. On the other hand, the Hall element 5 is located near the second rotation shaft 10 and detects the magnetic force of the magnet 4. In FIG. 4C, the magnetic force of the magnet 6a does not reach the Hall element 7, and it is still detected that the second housing 2 is opened in the short direction. On the other hand, the Hall element 5 continues to detect the magnetic force of the magnet 4.

  Thus, in the foldable mobile phone 100, when the second housing 2 is opened and closed with respect to the first housing 1 in the short direction, only the Hall element 7 is in the short direction of the second housing 2. However, the Hall element 5 does not detect the opening and closing of the second casing 2 in the short direction. When the second casing 2 is opened and closed with respect to the first casing 1 in the longitudinal direction, only the Hall element 5 detects the opening and closing of the second casing 2 in the longitudinal direction. The opening / closing of the second casing 2 in the longitudinal direction is not detected.

  Therefore, according to the present invention, in the foldable portable terminal device including two foldable shafts such as a foldable mobile phone and configured to be openable and closable in the longitudinal direction and the short direction, the second casing is folded. When opened from the normal state, it is possible to determine the display direction of the display unit by appropriately determining whether it is opened in the longitudinal direction or in the short direction.

  In the present embodiment, the Hall element is described as the magnetic force detection means. However, any element that detects magnetism may be used, and an MR element or the like may be used.

(Embodiment 2)
Next, as a second embodiment of the present invention, a wireless telephone communication means is further provided, and a line is automatically connected when the case is opened when an incoming call is received, and the line is disconnected when the case is closed after the line is connected. A foldable mobile phone equipped with is described.

  FIG. 5 is a block diagram showing main functional blocks of a foldable mobile phone 200 according to Embodiment 2 of the present invention. The foldable mobile phone 200 includes a transmission / reception unit 11 that transmits and receives radio waves from the mobile phone line through an antenna 11a. The transmission / reception unit 11 is connected to the line control unit 12. The line control unit 12 uses the line connection block 12a and the line disconnection block 12b to connect or disconnect the cellular phone line. The line control unit 12 is connected to the overall control unit 13 and is controlled by the overall control unit 13 to function as a mobile phone.

  An open / close detection control unit 14 is connected to the overall control unit 13. Further, the open / close detection control unit 14 is connected to the longitudinal direction detection unit already described as the Hall element 5 and the short direction detection unit described as the Hall element 7 in FIGS. 1 and 2. The open / close detection control unit 14 detects the folding state of the foldable mobile phone 200 using the longitudinal direction detection unit and the short direction detection unit. In addition, a speaker 15 and a microphone 16 are connected to the overall control unit 13, and the voice received from the transmission / reception unit 11 is output, or the voice is input and transmitted from the transmission / reception unit 11 to another mobile phone via the base station. Like to do.

  FIG. 6 shows a flowchart for explaining the operation of the folding cellular phone 200 according to Embodiment 2 of the present invention. The foldable mobile phone 200 of the present invention is characterized in that a line is not connected unless the second casing is opened in the longitudinal direction.

  In the foldable mobile phone 200, in the incoming call waiting state (step S1), when there is an incoming call (YES in step S2), it is checked whether or not the second casing 2 opens in the longitudinal direction. When the second casing 2 is opened in the longitudinal direction (YES in step S3), the line is connected and a call is started (step S4). If the second housing 2 is closed after the call (YES in step S5), the call is terminated and the line is disconnected (step S6).

  According to the present invention, in a foldable mobile phone having two rotation shafts that can be opened and closed in the longitudinal direction and the short direction, when the second casing is opened from the folded state, it opens in the longitudinal direction. It is determined alternatively whether it has been opened in the short direction. For this reason, the line is connected when it is opened in the longitudinal direction, but it is not detected that it has been opened in the longitudinal direction even though it was accidentally opened in the short direction, and the line is not connected when it is opened in the short direction. There is. FIG. 7 is a perspective view showing a state in which the second housing 2 is closed. FIG. 8 is a perspective view showing a state where the second housing 2 is slightly opened in the longitudinal direction. At this point, it is detected that the second casing 2 is opened in the longitudinal direction, and the line is connected. FIG. 9 is a perspective view showing a state when the second housing 2 is slightly opened in the short direction. Even if it opens in the short direction, the second casing 2 is not detected as being opened in the longitudinal direction, and the line is not connected.

(Embodiment 3)
In Embodiment 1 and Embodiment 2 of the present invention, in a foldable mobile phone that is provided with two rotating shafts and that can be opened and closed in the longitudinal direction and the lateral direction, the second casing is opened from the folded state. It was configured to be able to alternatively determine whether it was opened in the longitudinal direction or in the short direction. In Embodiment 3 of the present invention, when the second casing is opened in the longitudinal direction from the folded state, the second casing is opened before the longitudinal direction detecting means is opened by the longitudinal opening / closing detecting means. When the folded state is opened in the short direction, the short direction opening / closing detecting means detects that the second casing is opened before the long direction detecting means.

  FIG. 10 shows a front view of a foldable mobile phone 300 according to Embodiment 3 of the present invention. FIG. 10A shows a state where the second housing 2 is closed. A hinge portion 3 that can be opened and closed with respect to a first rotation shaft (not shown) is provided on the first housing 1 having the operation portion, and is connected to the second coaxial 10 of the hinge portion 3 so as to be freely opened and closed. There is a housing 2. The first casing 1 has a magnet 4, and the second casing 2 is provided with a longitudinal direction detection unit 5 facing it. The magnet 6 b is on the end surface of the hinge portion 3, and the short direction detection unit 7 is provided at a position facing the magnet 6 b of the second housing 2.

  FIG. 10B shows a state in which the second housing 2 is slightly opened in the short direction with respect to the second rotation shaft 10. At this time, the short direction detection unit 7 detects the magnetic force of the magnet 6 b, and the long direction detection unit 5 also detects the magnetic force of the magnet 4. When the second casing 2 is further opened and the opening angle of FIG. 11A is opened to Θ1, the short direction detection unit 7 does not detect the magnetic force of the magnet 6b, and the second casing 2 Is detected to open in the short direction. At this time, the longitudinal direction detection unit 5 detects the magnetic force of the magnet 4. When the second casing 2 is further opened and the opening angle in FIG. 11B is opened to Θ2, the longitudinal direction detection unit 5 does not detect the magnetic force of the magnet 4.

  Regarding the variation in the magnetic force and the sensitivity of the Hall element during mass production, the positional relationship between the short direction detection unit and the magnet and the longitudinal direction detection unit and the magnet is determined in consideration of the range of variation. Thus, the longitudinal direction detection unit can detect first when it opens in the longitudinal direction, and the short direction detection unit can detect first when it opens in the lateral direction.

  FIG. 12 illustrates a case where the magnetic force of the magnet 4 is smaller than the reference by ΔR. In FIG. 12, since the magnetic force of the magnet 4 is small, the longitudinal direction detection unit 5 does not detect the magnetic force of the magnet 4 when the opening angle of the second casing 2 is an angle Θ3 smaller than Θ2. However, when the opening angle of the second housing 2 reaches Θ3 in FIG. 12, it is after the short direction detection unit 7 has already detected that the second housing 2 has opened in the short direction. . FIG. 13 shows the relationship between the opening angles Θ1, Θ2, and Θ3. The detection angle Θ1 at which the short direction detection unit 7 detects that the second housing 2 is opened is based on the detection angles Θ2 and Θ3 at which the longitudinal direction detection unit 5 detects that the second housing 2 is opened. Small is enough. In this way, even if the magnetic force and the sensitivity of the Hall element vary during mass production, the short direction detection unit detects first when opening in the short direction by taking a margin and keeping it within the allowable range of variation. You can keep the relationship.

  In addition, the foldable mobile phone 300 according to the third embodiment of the present invention has a function of automatically connecting a line when a case is opened when an incoming call is received, and disconnecting the line when the case is closed after the line is connected. When the incoming call is received (step S1) and the incoming call is received (YES in step S2), whether or not the second casing 2 opens in the longitudinal direction as shown in the flowchart of FIG. Watching. When it is first opened in the longitudinal direction (YES in step S7), a line is connected and a call is started (step S4). If the second housing 2 is closed after the call (YES in step S5), the call is terminated and the line is disconnected (step S6).

  In the configuration of the third embodiment, the magnet 6b is provided on the end surface of the hinge part 3, and the short direction detection part 7 is provided in the second casing 2 at a position facing the magnet 6b, and opens in the longitudinal direction. In some cases, the longitudinal direction detection unit 5 indicates that the second casing 2 is opened, but the magnet 4 and the magnet 6a are provided in the first casing 1 of the first embodiment described above. Even in such a case, when opening in the longitudinal direction, the longitudinal direction detection unit 5 can be configured to detect that the second casing 2 has been opened first. That is, the detection angle at which the longitudinal direction detection unit 5 detects that the second casing 2 is opened is set smaller than the detection angle at which the short direction detection unit 7 detects that the second casing 2 is opened. In this case, the longitudinal direction detection unit 5 first detects that the second casing 2 is opened.

(Embodiment 4)
In the fourth embodiment of the present invention, the sensitivity of the longitudinal opening / closing detection means and the sensitivity of the short direction opening / closing detection means when the second casing is opened / closed with the central axis of the rotation axis as a reference are different. When the second casing is opened from the folded state, it can be alternatively determined whether the second casing is opened in the longitudinal direction or the short side. In the foldable mobile phone 400 according to the fourth embodiment of the present invention, as in the first to third embodiments, the longitudinal opening / closing detection means and the short direction with respect to the central axis of the rotation shaft This is effective when the positional relationship of the open / close detection means cannot be taken.

  FIG. 15 shows a front view of a foldable mobile phone 400 according to Embodiment 4 of the present invention. FIG. 15A shows a state in which the second housing 2 is slightly opened in the short direction. A hinge portion 3 that can be opened and closed with respect to a first rotation shaft (not shown) is provided on the first housing 1 having the operation portion, and is connected to the second coaxial 10 of the hinge portion 3 so as to be freely opened and closed. There is a housing 2. The first casing 1 includes a magnet 4 and a magnet 6c, and the second casing 2 is provided with a longitudinal direction detection unit 5 and a lateral direction detection unit 7 facing each other. When the second coaxial 10 is used as a reference, the short direction detection unit 7 is near and the long direction detection unit 5 is far from the short direction detection unit 7. This positional relationship is opposite to that in the first to third embodiments. However, the magnetic force of the magnet 4 is large, and the magnetic force of the magnet 6c is small. Therefore, as shown in FIG. 15 (a), the second casing 2 is opened in the short direction, and the short direction detection unit 7 does not detect the magnetic force of the magnet 6c and opens in the short direction. When this is detected, the longitudinal direction detection unit 5 is still detecting the magnetic force of the magnet 4.

  FIG. 15B shows a left side view when the folding cellular phone 400 is opened in the longitudinal direction. As shown in FIG. 15B, the magnetic force of the magnet 4 is large, but when it is opened in the longitudinal direction, the tip end portion of the second casing is greatly opened. For this reason, when the longitudinal direction detection unit 5 stops detecting the magnetic force of the magnet 4 and detects that the magnet 4 is opened in the longitudinal direction, the short direction detection unit 7 still detects the magnetic force of the magnet 6c.

  As described above, in the foldable mobile phone 400 according to the fourth embodiment of the present invention, it is opened in the longitudinal direction by making a difference between the sensitivity of the longitudinal opening / closing detection means and the sensitivity of the short direction opening / closing detection means. It is configured so that it can be determined alternatively whether it is opened in the short direction.

  As a method for making a difference between the sensitivity of the longitudinal opening / closing detection means and the sensitivity of the short direction opening / closing detection means, in addition to providing a difference in the magnetic force of the magnets 4 and 6c as described above, the method of making the difference between the longitudinal opening / closing detection means and short A difference may be made in the sensitivity of the Hall element used as the hand direction open / close detection means.

  In the above description, it has been shown that it is alternatively determined whether it is opened in the longitudinal direction or the lateral direction, but it is determined whether the longitudinal direction or the lateral direction is detected first. You may do it.

(Embodiment 5)
Embodiment 5 of the present invention will be described by omitting illustration. In the fifth embodiment of the present invention, each of the longitudinal opening / closing detection means and the short-side opening / closing detection means of the second casing is a set of protrusions and a mechanical switch that comes into contact with the contacts when pressed by the protrusions. Opening / closing detection means is configured. When the protrusion is provided on the first casing, the mechanical switch is disposed on the second casing. When the protrusion is provided on the second casing, the mechanical switch is disposed on the first casing. ing.

  When the mechanical switch is pushed by the protrusion, it is determined that the second casing is closed, and when the mechanical switch is not pressed by the protrusion, it is determined that the second casing is opened. Then, with respect to the arrangement of the longitudinal opening / closing detection means and the short direction opening / closing detection means, the longitudinal direction opening / closing detection means is arranged close to the center axis of the second rotation axis, and the short direction opening / closing detection means is arranged in the longitudinal direction It is arranged farther than the open / close detection means. Thus, when the second casing is opened in the short direction, it can be detected that the short direction opening / closing detection means is opened first.

  In addition, the short direction opening / closing detection means is disposed close to the central axis of the first rotation axis, the long direction opening / closing detection means is disposed farther than the short direction opening / closing detection means, and the second casing Is opened in the longitudinal direction, the longitudinal opening / closing detection means detects that the second casing has been opened first. As a result, it is possible to alternatively determine whether it has been opened in the longitudinal direction or in the lateral direction, so that the folding type has two rotation shafts and can be opened and closed in the longitudinal direction and the lateral direction. In a mobile phone, when the second casing is opened from the folded state, the display direction of the display unit is determined by appropriately determining whether the second casing is opened in the longitudinal direction or the lateral direction.

Embodiment 6 of the present invention will also be described with illustration omitted. In Embodiment 6 of the present invention, the longitudinal opening / closing detection means and the short-side opening / closing detection means of the second casing each constitute a set of opening / closing detection means with a light shielding member and an optical sensor. When the light sensor is shielded by the light shielding member, it is determined that the second housing is closed, and when the light sensor is not shielded by the light shielding member, it is determined that the second housing is open. Then, with respect to the arrangement of the longitudinal opening / closing detection means and the short direction opening / closing detection means, the longitudinal direction opening / closing detection means is arranged close to the center axis of the second rotation axis, and the short direction opening / closing detection means is arranged in the longitudinal direction. It is arranged farther than the open / close detection means.

  Thus, when the second casing is opened in the short direction, it can be detected that the short direction opening / closing detection means is opened first.

  In addition, the short direction opening / closing detection means is disposed close to the central axis of the first rotation axis, the long direction opening / closing detection means is disposed farther than the short direction opening / closing detection means, and the second casing Is opened in the longitudinal direction, the longitudinal opening / closing detection means detects that the second casing has been opened first. As a result, it is possible to alternatively determine whether it has been opened in the longitudinal direction or in the lateral direction, so that the folding type has two rotation shafts and can be opened and closed in the longitudinal direction and the lateral direction. In a mobile phone, when the second casing is opened from the folded state, the display direction of the display unit is determined by appropriately determining whether the second casing is opened in the longitudinal direction or the lateral direction. Can do.

  The present invention is not limited to a foldable mobile phone, and has two rotating shafts in a longitudinal direction and a lateral direction, such as a game machine that uses a display screen that is switched between portrait and landscape, and a PDA that has a television reception function. The present invention can be applied to a foldable portable terminal device that can be opened and closed.
