Description

  The present invention relates to a mobile phone that can be switched between a closed state in which two housings overlap each other and an open state in which the overlapping is eliminated.

  In recent years, a so-called slide type mobile phone in which an upper housing and a lower housing are relatively movable is widely used. Here, whether the mobile phone is in the open state or the closed state is determined by a magnet built in the upper housing and a magnetic sensor built in a position facing the magnet in the closed state of the lower housing. (See Patent Document 1). In this case, when the magnetic sensor is sensitive to the magnetic force generated by the magnet, it is determined to be in a closed state, and the magnet and the magnetic sensor are spatially separated by the user's sliding operation, and the magnetic force generated by the magnet is detected. When the magnetic sensor becomes insensitive, it is determined to be open.

  By the way, in the slide type mobile phone as described above, in the case of a terminal provided with a touch panel in the lower housing, a slide operation by the user is started from the closed state, and a part of the display of the lower housing has been exposed. Sometimes, if the display remains off, the user feels stressed by misunderstanding that the display of the lower housing is broken or the display is slow to turn on. In order to avoid this, if the touch panel display is turned on and operated immediately after the start of the slide operation, the touch panel of the lower housing in which the user's finger or the like is exposed and activated during the slide operation is now displayed. May accidentally touch the screen and cause malfunction. For example, if a function to make a call to a predetermined call destination with a single touch on the touch panel is triggered by an erroneous contact with the touch panel, an unnecessary call contrary to the user's intention may be charged. Become.

  In view of the above problems, an object of the present invention is to provide a mobile phone that can reduce malfunctions when switching between a closed state and an open state.

  In order to solve the above-described problems, the present invention provides a mobile phone in which two casings are switchable between an overlapped closed state and an open state in which the overlap is eliminated. A second housing in which a first touchpad is disposed on a surface facing the first housing in a state, a first sensor that detects a closed state, a second sensor that detects an open state, When the first sensor no longer detects the closed state, the input operation of the first touch pad is kept unacceptable, and the input of the first touch pad is detected after the second sensor detects the open state. A control unit that receives an operation.

  With the above-described configuration, the mobile phone of the present invention can provide a mobile phone that can reduce malfunctions when switching between a closed state and an open state.

  In a mobile phone according to an embodiment of the present invention, a first housing and a second housing each having a touch panel are connected to each other via a swing arm (also referred to as a pivot hinge) so as to be rotatable and swingable. As a result, the second housing performs a combined movement of rotation and swing with respect to the first housing, thereby switching between a closed state where the two housings overlap and an open state where the overlapping is eliminated. Is done. The touch panel of the second housing is arranged on the surface facing the first housing in the closed state, and the touch panel of the first housing is opposite to the surface facing the surface where the second housing has the touch panel in the closed state. It is arranged on the main surface of the side. In the open state, the two casings are in a state in which their one edges are close to each other, the touch panels of both casings face the same direction, and the touch panels of both casings have a predetermined obtuse angle or more. Make an angle.

When the mobile phone detects that the user has switched from the closed state to the open state and has exited the closed state, the mobile phone turns on the exposed touch panel display of the second housing. This is because the user may misunderstand that the touch panel is out of order or the reaction speed is slow when it is not lit. When this user performs this switching operation, a part of the body such as a finger holding the second housing may come into contact with the touch panel of the second housing. In addition, one end of the first housing may be brought into contact with the touch panel of the second housing as the first housing rotates and swings with respect to the second housing. In the case where the user touches the touch panel not intended by the user, the mobile phone recognizes the unintended contact as a user instruction and performs control so as not to malfunction. Hereinafter, the mobile phone 1 according to an embodiment of the present invention will be described in detail.
1. Configuration (1) Outline FIGS. 1 and 2 are perspective views showing an appearance of a mobile phone 1.

  The mobile phone 1 is formed by connecting a first housing 2 and a second housing 3 by a pivot hinge 4 as a swing arm. When the user performs a switching operation so that the first housing 2 and the second housing 3 move relative to each other, the external appearance is four states (hereinafter referred to as “opening / closing”, a closed state, a transient state, a tilt state, and a fully open state). Transitions between "states"). 1A shows a closed state, FIG. 1B shows a transient state, FIG. 2A shows a tilt state, and FIG. 2B shows a fully open state. In the present embodiment, the tilt state and the fully open state are collectively referred to as the open state.

  The transition between the four states will be described with reference to FIG. 3 which is a side view of the mobile phone 1. 3, FIG. 3 (a) is shown in FIG. 1 (a), FIG. 3 (b) is shown in FIG. 1 (b), FIG. 3 (c) is shown in FIG. 2 (a), and FIG. This corresponds to 2 (b). Here, as shown in FIG. 3B, the pivot hinge 4 pivotally supports the second housing 3 at the base end portion 4p so as to be rotatable and swingable, and rotates the first housing 2 at the distal end portion 4q. In addition, the connecting member is pivotally supported so that the arm portion 4r is formed between the distal end portion 4q and the base end portion 4p.

  The closed state of the mobile phone 1 is a state in which the first housing 2 and the second housing 3 overlap each other as shown in FIG. Here, as shown in FIG. 1, FIG. 2 and FIG. 3, the end on the base end 4p side of the pivot hinge 4 in the second housing 3 is referred to as the upper end 3u, and from the base end 4p of the pivot hinge. The opposite end on the opposite side is referred to as the lower end 3d. Further, the end of the first housing 2 that is close to the upper end 3u in the closed state is referred to as the upper end 2u, and the end that is closer to the lower end 3d is referred to as the upper end 2u.

In this closed state, when the user biases near the lower end 3d of the first housing 2, as shown in FIG. 3 (b), the arm 4r rises due to the rotation at the base end 4p of the pivot hinge 4. The first housing 2 also rises by rotating and swinging about the rotation axis of the tip 4q of the pivot hinge 4. This state is a transient state.
When the user continues to be biased, the first housing 2 further performs a combined movement of rotation and swinging with respect to the second housing 3, and the lower end 2 d of the first housing 2 is one of the second housing 3. It moves along the main surface 3a so as to be close to the upper end 3u of the second housing 3. As shown in FIG. 3C, the lower end 2d of the first housing 2 and the upper end 3u of the second housing 3 are close to each other, and the first housing 2 is opposed to the second housing 3. It will be in the state where it inclined backward by a predetermined obtuse angle.

This state is a tilt state. Here, an obtuse angle formed by one main surface 2a of the first housing 2 and one main surface 3a of the second housing 3 is α. In this embodiment, the tilt state refers to a state where α is 140 ° or more and less than 180 °. However, the angle at which α is tilted is changed according to the design. You can do it.
In this state, the user urges the first casing 2 in the direction in which the first casing 2 further tilts backward toward the upper end 2u and the lower end 2d of the first casing 2 as shown in FIG. In addition, the surface 2a of the first housing 2 and the surface 3a of the second housing 3 are aligned on substantially the same plane. This state is called a fully opened state.

This completes the description of the transition between the four states, and then the outline of the configuration will be described.
As shown in FIG. 1A and the like, the first housing 2 includes a first touch panel 10 on the surface 2a, and incorporates a magnet 5 on the inner side by a distance L from the side surface portion 2r in the vicinity of the lower end portion 2d.
The second housing 3 includes a second touch panel 11 on the surface 3a. The second housing 3 incorporates the first magnetic sensor 12 at a position where the magnetic force generated by the magnet 5 (hereinafter referred to as “generated magnetic force”) can be sensed. As an example, the first magnetic sensor 12 is built in the second housing 3 at a distance L from the side surface portion 3r in the vicinity of the lower end portion 3d and facing the magnet 5 in the closed state.

Further, the second housing 3 is located at a position within a range where the magnetic force of the magnet 5 (shown as 5a in FIG. 2 (a) and 5b in FIG. 2 (b)) can be sensed both in the tilted state and in the fully opened state. A second magnetic sensor 13 is incorporated. As an example, the second magnetic sensor 13 is built in the second housing 3 in the vicinity of the upper end 3u by a distance L from the side surface 3r.
In the mobile phone 1, when the first magnetic sensor 12 is sensitive to the magnetic force generated by the magnet 5, it is determined to be in the closed state, and the first magnetic sensor 12 cannot sense the magnetic force generated by the magnet 5. If it is determined that the transition from the closed state to the transition state. Further, while neither the first magnetic sensor 12 nor the second magnetic sensor 13 is sensitive to the magnetic force generated by the magnet 5, it is determined to be in a transient state, and the magnetic force generated by the magnet 5 is determined to be the second magnetic sensor. When 13 is sensed, it is determined that the transition is made from the transient state to the tilt state.

The timing at which the positional relationship between the first housing 2 and the second housing 3 transitions from the tilted state to the fully opened state is due to the sensitivity of the magnetic force generated by the magnet 5 by the first magnetic sensor 12 or the second magnetic sensor 13. Although this determination cannot be made, this determination will be described later.
Note that the first magnetic sensor 12 and the second magnetic sensor 13 have directivity in the direction of the rotation axis of the pivot hinge 4 indicated by arrows 12a and 13a in FIGS. It shall have. In this case, the magnetic force (magnetic force 5a, 5b, etc.) generated by the magnet 5 is adjusted by appropriately adjusting the distance L described above (for example, about 1 cm. This value varies depending on the size of the magnet). In either the tilted state or the fully open state, the second magnetic sensor 13 can be made to respond in a manner that does not leak outside the first housing 2 and the second housing 3. The same applies to the closed state.

If the first magnetic sensor 12 and the second magnetic sensor 13 have directivity related to magnetic force sensitivity in a direction perpendicular to the main surface 3a of the second housing 3, the magnetic force is applied to the second magnetic sensor 13. Therefore, the magnetic force must be generated in the vertical direction with respect to the main surface 3a, and the magnetic force must reach the outside of the housing. The magnetic force generated with respect to the outside of the housing can adversely affect other nearby devices such as malfunction.
(2) Internal Configuration Next, the internal configuration of the mobile phone 1 will be described.

FIG. 4 is a block diagram showing an internal configuration of the mobile phone according to the embodiment of the present invention.
The mobile phone 1 includes a magnet 5, a first touch panel 10, a second touch panel 11, a first magnetic sensor 12, a second magnetic sensor 13, a timer 14, an antenna 15, a wireless communication unit 16, a signal processing unit 17, a microphone 18, and a receiver. 19, the control part 20 and the display control part 21 are comprised.

  Specifically, the cellular phone 1 is a computer system including a microprocessor, a ROM, a RAM, a display unit, a keypad, a wireless communication unit, and an antenna. A computer program is stored in the RAM. The cellular phone 1 achieves its functions by the microprocessor operating according to the computer program.

The first magnetic sensor 12 and the second magnetic sensor 13 sense the magnetic force generated by the magnet 5 (hereinafter referred to as “generated magnetic force”), and control that it has sensed or no longer senses the sensitive magnetic force. This is a magnetic sensor that notifies the unit 20. As an example, the first magnetic sensor 12 and the second magnetic sensor 13 notify the control unit 20 using an interrupt.
Here, the strength of the magnetic force by the magnet 5 is such that the first magnetic sensor 12 is sensitive in the closed state and the second magnetic sensor 13 is sensitive in the tilted state. The first magnetic sensor 12 and the second magnetic sensor are used. Both of them are adjusted so as not to sense the magnetic force at the same time.

The timer 14 measures time, and holds a timer waiting time when a predetermined timer waiting time is set by the control unit 20. Then, when the timer waiting time elapses from when the control unit 20 sets the timer waiting time, the control unit 20 is notified thereof. This notification uses an interrupt as an example.
The wireless communication unit 16 performs wireless communication with a base station (not shown) via the antenna 15, demodulates the received signal, and transmits it to the signal processing unit 17. The radio communication unit 16 modulates the signal received from the signal processing unit 17 and transmits the modulated signal to the base station via the antenna 15.

  The signal processing unit 17 demodulates a baseband signal indicating sound from the signal received from the wireless communication unit 16, converts the baseband signal as a demodulation result into a sound signal, and outputs the sound signal to the receiver 19. Further, the signal processing unit 17 receives a call signal from the microphone 18, converts the call signal into a baseband signal, modulates it, and transmits it to the wireless communication unit 16. The signal processing unit 17 also performs other processing related to audio signals such as outputting a ringtone to a speaker (not shown).

The microphone 18 collects the voice uttered by the user during a call and converts it into a call signal that is an electrical signal, and transmits the call signal to the signal processing unit 17.
The receiver 19 receives the audio signal generated by the signal processing unit 17, converts the received audio signal into audio, and amplifies the sound.
The first touch panel 10 includes a first display 31 and a first touch pad 32. The first display 31 performs image display and the like according to control by the display control unit 21. The first touch pad 32 acquires a user instruction made by the user touching the surface and notifies the control unit 20 of the user instruction. When the first display 31 is lit, the first touch panel 10 is also lit, and when the input operation is performed on the first touch pad 32, the input operation is also performed on the first touch panel 10. The first touch panel 10 corresponds to the second touch panel in the claims, and the first display 31 and the first touch pad 32 correspond to the second display and the second touch pad in the claims, respectively. .

  The second touch panel 11 includes a second display 33 and a second touch pad 34. The second display 33 performs image display and the like according to control by the display control unit 21. The second touch pad 34 acquires a user instruction made by the user touching the surface and notifies the control unit 20 of the user instruction. Note that when the second display 33 is turned on, the second touch panel 11 is also turned on, and when an input operation is performed on the second touch pad 34, an input operation is also performed on the second touch panel 11. The second touch panel 11 corresponds to the first touch panel in the claims, and the second display 33 and the second touch pad 34 correspond to the first display and the first touch pad in the claims, respectively. .

  The display control unit 21 generates videos, images, and the like to be displayed on the first display 31 and the second display 32 and displays them on the first display 31 and the second display 32, respectively. In addition, the display control unit 21 receives instructions from the control unit 20, controls on / off of the first display 31 and the second display 32, and displays images to be displayed on the first display 31 and the second display 32 during lighting. Generation and display control, adjustment of luminance used for image display, and the like are performed.

The control unit 20 controls the overall operation of the mobile phone 1.

2. Operation Hereinafter, the operation related to the state transition of the mobile phone 1 will be described focusing on the control processing by the control unit 20.

The control unit 20 manages the state transition between the above-described four states in the mobile phone 1 using the state information. The state information is information indicating which of the four states the open / close state of the mobile phone 1 is, and is any one of “closed state”, “transient state”, “tilt state”, and “fully open state”. Indicates.
FIG. 5 is a state transition diagram for the open / closed state managed by the control unit 20.

(A) Closed state The control unit 20 determines that the open / closed state is the closed state when only the first magnetic sensor 12 is sensitive to the generated magnetic force and the second magnetic sensor 13 is not sensitive to the generated magnetic force. When determining that the open / close state has transitioned to the closed state, the control unit 20 rewrites the state information to the closed state.
When the control unit 20 determines that the open / closed state has transitioned to the closed state, the control unit 20 turns off the second display 33. When the open / close state is the closed state, the first casing 2 and the second casing 3 are overlapped, and the second touch panel 11 of the second casing 3 is not exposed, so the second display 33 is turned off. This is to reduce power consumption. In the closed state, the control unit 20 does not accept user input using the second touchpad 34. This is because the user cannot touch the second touch pad 34.

When the state information indicates the closed state, the control unit 20 determines that the transition to the transient state occurs when the interrupt notification indicating that the generated magnetic force is no longer sensed is received from the first magnetic sensor 12.
(B) Transient state The control unit 20 determines that the open / close state is a transient state when neither the first magnetic sensor 12 nor the second magnetic sensor 13 is sensitive to the generated magnetic force. When the control unit 20 determines that the open / close state has transitioned to the transient state, the control unit 20 rewrites the state information to the transient state.

  When the control unit 20 determines that the open / close state has transitioned to the transient state, the control unit 20 lights the second display 33 to display an image. This is because when the open / closed state transitions from the closed state to the transitional state, the second touch panel 11 is exposed unlike the closed state. At this time, if the second display 33 remains off, This is because the user may misunderstand that the second display 33 has failed, which may be stressful for the user.

  In addition, the control unit 20 does not accept user input using the second touch pad 34 in a transient state. That is, the second touch pad 34 is turned off. This is because, in a transient state, the lower end 2d of the first housing 2 may come into contact with the second touch pad 34 of the second housing 3, and this contact is regarded as an input to the second touch pad 34. This is because the mobile phone 1 will perform an operation contrary to the user's intention. In the present embodiment, it is assumed that the user does not intend to perform an operation using the second touch pad 34 in a transient state.

When the state information indicates a transient state, the control unit 20 determines that the first magnetic sensor 12 transitions to the closed state when receiving an interrupt notification indicating that the generated magnetic force is sensitive. In addition, when the state information indicates a transient state, the control unit 20 determines that the state transitions to the tilt state when the second magnetic sensor 13 receives an interrupt notification indicating that the generated magnetic force has been sensed.
(C) Tilt State When the second magnetic sensor 13 is sensitive to the generated magnetic force and the first magnetic sensor 12 is not sensitive to the generated magnetic force, the control unit 20 determines that the open / close state is the tilt state. When the control unit 20 determines that the open / close state has shifted to the tilt state, the control unit 20 rewrites the state information to the tilt state.

  When the open / close state is the tilt state, the control unit 20 lights the second display 33 and does not accept a user input using the second touch pad 34. This is because when the user urges the first housing 2 and the second housing 3 to change the open / close state of the mobile phone 1 from the tilted state to the fully opened state, the finger or the like is accidentally moved to the second housing 3. This is because the mobile phone 1 may operate against the user's intention when it is determined that the touch is an input to the second touch pad 34. In the control in the present embodiment, the user basically has little intention to perform an operation using the second touch pad 34 in the tilted state, and the user uses the second touch pad 34 in the fully opened state. It is assumed that there are many intentions to do.

  In the case where the open / close state indicates the tilt state, the control unit 20 determines that the fully open state transitions when the fully open operation time has elapsed since the open / close state transitioned to the tilt state. Here, the transition to the fully open state after the transition to the tilt state is determined because the user grips and moves the first casing 2 of the mobile phone 1 to change to the fully open state. This is because it is assumed that the first casing 2 is further energized after the tilting state is changed to the fully opened state after the fully opened operation time has elapsed. In the present embodiment, the fully open operation time is about 0.5 seconds as an example, but is not limited to this, and may be an appropriate time required from the tilt state to the fully open state.

  Regarding the measurement of the full-open operation time, the control unit 20 sets the full-open operation time as a timer waiting time in the timer 14 when transitioning to the tilt state, and accepts an interrupt from the timer 14 after the full-open operation time has elapsed. When receiving this interrupt, the control unit 20 changes the state information from the “tilt state” to the “fully open state”. Further, when the state information indicates the tilt state, the control unit 20 determines that the transition to the transient state occurs when the second magnetic sensor 13 receives an interrupt notification indicating that the generated magnetic force is no longer sensitive.

(D) Fully open state The control unit 20 is fully open after the second magnetic sensor 13 is sensitive to the generated magnetic force, the first magnetic sensor 12 is not sensitive to the generated magnetic force, and the open / closed state transitions to the tilt state. When it is determined that the time has elapsed, it is determined that the open / close state is the fully open state.
When the control unit 20 determines that the open / close state has transitioned to the fully open state, the control unit 20 turns on the second display 33 and accepts a user input using the second touch pad 34.

  Regardless of whether the tilting state continues for about the fully open operation time and then the user actually urges the first housing 2 and the second housing 3 to change the open / close state to the fully open state. , Make the state information fully open. That is, the control unit 20 rewrites the state information to the fully open state even though the actual open / close state of the mobile phone 1 is the tilt state. Then, the state information indicates the fully open state, and the user's input using the second touch pad 34 is accepted. Therefore, the actual open / close state is not desired to be fully opened, and the tilt state is used. It is possible to perform an action that matches the user's wishes that are considered desired.

When the state information indicates the fully open state and the second magnetic sensor 13 receives an interrupt notification indicating that the generated magnetic force is no longer sensitive, the control unit 20 determines that the state transitions to the transient state.
Next, a startup state determination process for determining in which state the open / close state when the power of the mobile phone 1 is switched from the off state to the on state in the control unit 20 will be described.

FIG. 6 is a flowchart showing the startup state determination process.
First, the control unit 20 of the mobile phone 1 determines whether or not the second magnetic sensor 13 is sensitive to the generated magnetic force (S01). If it is sensitive (S01 = YES), the open / close state is the fully open state. The state information is rewritten to the fully open state. When it is determined that the second magnetic sensor 13 is not sensitive to the generated magnetic force (S01 = NO), it is further determined whether the first magnetic sensor 12 is sensitive to the generated magnetic force (S02).

When it is determined that the first magnetic sensor 12 is sensitive to the generated magnetic force (S02 = YES), the control unit 20 determines that the open / close state is the closed state, and rewrites the state information to the closed state (S03).
When it is determined that the first magnetic sensor 12 is not sensitive to the generated magnetic force (S02 = NO), the control unit 20 determines that the open / close state is a transient state, and rewrites the state information to the transient state (S04).

After the startup state determination process, the control unit 20 manages the state transition according to the state transition diagram shown in FIG.

As described above, according to the above embodiment, when the second touch panel 11 is exposed when the second touch panel 11 is exposed from the closed state, the second touch panel 11 (second display 33) is already lit. There is no misunderstanding that the performance of the mobile phone 1 itself is bad because the second touch panel 11 of the housing 3 is broken or the second touch panel 11 is turned on slowly, and the user feels unnecessary stress. Can be avoided. In addition, even if the user's finger or the like comes into contact with the second touch panel 11 (second touch pad 34) in accordance with the switching operation until the user exits from the closed state to the open state, the user misunderstands the input operation and malfunctions. Can be avoided.

  Further, when the second magnetic sensor 13 no longer detects the open state, the control unit 20 stops accepting an input operation for the second touch panel 11 (second touch pad 34), and then the first magnetic sensor 12 is detected. The second touch panel 11 (second display 33) is kept on until the closed state is detected, and the second touch panel 11 (second display 33) is turned on when the first magnetic sensor 12 detects the closed state. Turns off.

  With this configuration, when the user performs a switching operation from the open state to the closed state, the second touch panel 11 (second display 33) is turned off despite the exposure, and the user instantaneously Since there is no misunderstanding that the second touch panel 11 (second display 33) of the body 3 has failed, the user can avoid feeling unnecessary stress. Further, even when the user's finger or the like comes into contact with the second touch panel 11 (second touch pad 34) during the switching operation from the open state to the closed state, it is avoided that the input operation is misunderstood and erroneously operated. be able to.

  In addition, the first housing 2 has a first touch panel 10 (first touch panel 10) on the main surface opposite to the surface in which the second housing 3 has the second touch panel 11 (second touch pad 34) in the closed state. 1 touch pad 32), and the first housing 2 and the second housing 3 are connected to each other via a swing arm so as to be rotatable and swingable. The casing 3 is configured to be able to switch between a closed state and an open state by performing a combined movement of rotation and swing, and in the open state, the two casings are in a state in which one edge of each other is close to each other. In addition, the second touch panel 11 (second touch pad 34) and the first touch panel 10 (first touch pad 32) are in the same direction, and the second touch panel 11 (second touch pad 34) and the first touch panel 11 are also in the same direction. Touch panel 10 (first touch pad Angle of 2) is maintained at a predetermined obtuse angle.

With this configuration, it is possible to limit the input operation to the second touch panel 11 (second touch pad 34) after the first touch panel 10 and the second touch panel 11 are completely exposed.
The first magnetic sensor 12 and the second magnetic sensor 13 are magnetic sensors, and the end of the first housing 2 that is close to the edge of the second housing 3 when the two housings are in the closed state. A magnet is arranged in the vicinity of the edge, and the first magnetic sensor 12 is provided in the vicinity of the edge of the second housing 3 in an area where the magnet can be sensitive to the magnetic force of the magnet, while the two housings are in an open state. In some cases, the second magnetic sensor 13 is provided in the vicinity of a different edge of the second housing 3 in an area where the magnetic force of the magnet 5 can be sensed.

With this configuration, the first magnetic sensor 12 and the second magnetic sensor 13 can be sensitive to the magnetic force generated by the magnet 5 within the area, so that the magnet 5 or the first magnetic sensor can be compared with a simple mechanical switch or the like. The arrangement of the 12 and the second magnetic sensor 13 can be made flexible, and the device design becomes easy.
Moreover, the control part 20 starts reception of input operation of the 2nd touch panel 11 (2nd touchpad 34), when the open state is detected for a predetermined period after the 2nd magnetic sensor 13 detects an open state.

With this configuration, when the user has an intention to use the touch panel (touch pad) in both cases when the angle between the touch panels in both cases is maintained at a predetermined obtuse angle, the angle formed by the touch panels (touch pads) in both cases is equal to or greater than the predetermined angle. In particular, it can operate in any case where it has an intention to use it in the same plane.
Moreover, the 1st magnetic sensor 12 and the 2nd magnetic sensor 13 are good also as having the directivity of the rotating shaft direction of the 1st housing | casing 2 and the 2nd housing | casing 3 as a directivity for detecting magnetic force.

With this configuration, the magnet 5, the first magnetic sensor 12, and the second magnetic sensor 13 can be arranged so that the magnetic force generated by the magnet 5 does not reach the outside of the mobile phone.
Further, the control unit 20 turns on the second touch panel 11 (second display 33) after the first magnetic sensor 12 no longer detects the closed state until the second magnetic sensor 13 detects the open state. At the same time, the second touch panel 11 (second display 33) may be turned on with lower brightness than in the open state.

With this configuration, it is possible to reduce power consumption while avoiding misunderstandings such as failure and slow reaction by the user.
3. Modifications The embodiment of the mobile phone according to the present invention has been described above. However, the illustrated mobile phone can be modified as follows, and the present invention is applied to the mobile phone as shown in the above-described embodiment. Of course, it is not limited.

For example, an optical sensor may be used instead of the magnetic sensor. In this case, as an example, the first optical sensor is arranged at a position where light is not detected when the open / close state is closed, and the second optical sensor is opened in the open state. Sometimes it is placed in a position to detect light.

A mechanical switch may be used instead of the magnetic sensor. In this case, as an example, the first mechanical switch is arranged at a position that is turned on when the open / close state is closed, and the second mechanical switch is opened in the open state. At the position where it is turned on.
(2) Although the brightness of the second display 33 is not particularly described in the above-described embodiment, the brightness may be lower in the transient state than in the open state. Thereby, power consumption can be reduced. In the transient state, it is considered that the user does not accept the input of the instruction to the second touch pad 34, the user will not stare at the second display 33, and the second display 33 is even lit. This is because it is considered that there is no misunderstanding such as failure or dull reaction in the user.

  (3) Although not particularly described in the above-described embodiment, the magnet can be obtained by appropriately selecting the magnets constituting the magnet 5 or the sensors constituting the first magnetic sensor 12 and the second magnetic sensor 13. The distance between the magnet and the magnetic sensor until the magnetic sensor senses the generated magnetic force can be adjusted. Thereby, for example, it is determined that the magnet 5 and the first magnetic sensor 12 have left the closed state when they are separated by 0.5 centimeters, and it is determined that they have left the closed state when they are separated by 1 centimeter. Etc. can be adjusted, and flexible device design becomes possible. Similarly, in the open state, it is determined that the tilt state is reached when the distance between the magnet 5 and the second magnetic sensor 13 approaches 0.5 centimeters, or the tilt state is reached when it approaches 1 centimeters. This makes it possible to make adjustments, and flexible device design becomes possible.

(4) In the above embodiment, the second touch pad is turned off in the transient state (FIG. 5), but the touch pad is not turned off, for example, data input from the touch pad is invalidated. The process may be as follows.
(5) A cellular phone processor that performs processing for controlling the state transition shown in the embodiment, state determination processing at start-up, and the like, and a program code in a machine language or high-level language that is executed by various circuits connected to the processor It is also possible to record a control program consisting of the above in a recording medium, or to distribute and distribute it via various communication paths. Such a recording medium includes an IC card, a hard disk, an optical disk, a flexible disk, a ROM, a flash memory, and the like. The distributed and distributed control program is used by being stored in a memory or the like that can be read by the processor, and the processor executes the control program to realize each function as shown in each embodiment. Will come to be. In addition to directly executing the control program, the processor may be compiled and executed or executed by an interpreter.

  (6) Each functional component shown in the above embodiment may be realized as a circuit that executes the function, or may be realized by executing a program by one or a plurality of processors. Moreover, it is good also as what is comprised as a package of IC, LSI, and other integrated circuits. This package is incorporated into various devices for use, whereby the various devices realize the functions as shown in the embodiments.

(7) In the above-described embodiment, the example using the pivot hinge has been described. However, the present invention is not limited to this, and may be realized as a mobile phone such as a system using a hinge of another shape or a slide type.
(8) Although the above embodiment has been described with an example of a mobile phone, the present invention can also be realized as a portable information device terminal having the same configuration and function.
(9) The above-described embodiments and modifications may be partially combined.

  The mobile phone of the present invention is a mobile phone having two screens, each of which is a touch panel, and is particularly suitable for executing an application with a large image display.
