First Embodiment A foldable mobile phone is illustrated as a first embodiment.
1A and 1B are an external perspective view of a foldable mobile phone according to the present embodiment and an external cross-sectional view of the mobile device device 1.
The foldable mobile phone 1 includes a first housing 3, a second housing 4, and a connecting portion 5. The first housing 3 and the second housing 4 are in a facing state in which the first housing 3 and the second housing 4 are illustrated by a solid line in FIG. Alternatively, it is configured to be openable and closable so as to take a separated state illustrated by a broken line in FIG.

The first housing 3 includes a first housing upper portion 3a and a first housing lower portion 3b which are separated by a first housing dividing portion 3c. The first housing upper part 3 a and the first housing lower part 3 b are combined to form a first housing 3.
The second housing 4 also has a second housing upper portion 4a and a second housing lower portion 4b which are divided by the second housing dividing portion 4c. The second housing upper portion 4a and the second housing lower portion 4b are combined to form a second housing 4 integrally.

A key input unit 10 having a numeric key switch, a function selection button, and the like is disposed on the surface of the first housing upper part 3a.
As an example of the display means of the present invention, for example, a display unit 12 such as a liquid crystal display is disposed on the second housing upper part 4a.

FIGS. 2A and 2B are diagrams showing an arrangement example of the geomagnetic sensor 170, the magnetic sensor 180, and the magnet 190 in the foldable mobile phone 1 illustrated in FIGS. 1A and 1B. .
The magnetic sensor 180 and the magnet 190 are arranged to detect the open / closed state of the first housing 3 and the second housing 4. As illustrated by the solid line in FIG. 2B, when the first housing 3 and the second housing 4 face each other, the magnetic force sensor 180 and the magnet 190 face each other. Sensitive to strong magnetism from 190.
On the other hand, as shown by the broken line in FIG. 2B, when the first housing 3 and the second housing 4 are in the open state in which they are separated from each other, the magnetic force sensor 180 does not respond to the magnetism of the magnet 190.
A case open / close detection processing unit 160 described later with reference to FIG. 3 determines the open / closed state of the first case 3 and the second case 4 according to the magnetic value detected by the magnetic force sensor 180.

  As described above, the geomagnetic sensor 170 is arranged at a position where the magnetism 190 is not affected as much as possible even when the first casing 3 and the second casing 4 face each other and the casing is closed. It is desirable that

FIG. 3 is a diagram illustrating some of the components mainly including the signal processing unit 100 in the foldable mobile phone 1 mounted (arranged) in the first housing 3 and the second housing 4.
An arrangement example of these components will be described.
The first housing lower part 3b includes a wireless communication unit 101, a GPS signal receiving unit 102, a transaction (transaction, TR) processing communication unit 103 that constitutes a part of the non-contact communication means of the present invention, an audio processing unit 104, A storage unit 109, a power switch unit 110, a battery unit 111, and a signal processing unit 150 are arranged (mounted).
In addition to the key input unit 10, a microphone 106 connected to the audio processing unit 104 is disposed in the first housing upper part 3 a. In addition, a speaker 105 connected to the sound processing unit 104 is disposed in the second housing upper portion 4a.
The wireless communication antenna 121, the GPS antenna 122, and the transaction (TR) antenna 123 that constitutes a part of the non-contact communication means of the present invention are the first housing lower portion 3b or the second housing lower portion 4b, respectively. It is arranged at an appropriate place.

The magnetic field generated by the reader / writer device 200 used in a non-contact communication system using electromagnetic waves by the non-contact IC card function, for example, FeliCa (registered trademark), Suica (registered trademark), etc. is much stronger than the geomagnetism. As a result, when non-contact communication using electromagnetic waves is performed between the mobile phone 1 and the reader / writer device 200, the geomagnetic sensor 170 that detects geomagnetism is affected by the magnetic field generated by the reader / writer device 200, and is accurate. There are cases where geomagnetism cannot be detected.
The TR antenna 123 is used, for example, by bringing the mobile phone 1 close to or in contact with a reader / writer device 200 for non-contact communication processing such as FeliCa and Suica. For example, when using Suica, the TR antenna 123 mounted on the folding cellular phone 1 is brought close to the access window of an automatic ticket gate installed at the ticket gate of a station, or the cellular phone 1 is brought into contact with the access window. To use. Inside the access window have been accommodated reader / writer apparatus 200 radiates electromagnetic waves for non-contact communication.
As a result, the geomagnetic sensor 170 mounted on the mobile phone 1 is positioned within the effective area of the electromagnetic wave radiated from the reader / writer device 200.
In such a case, it is desirable that the geomagnetic sensor 170 and the TR antenna 123 be arranged apart from each other so that the geomagnetic sensor 170 is not affected by magnetism due to electromagnetic waves from the reader / writer device 200 as much as possible.
For example, as illustrated in FIG. 1A, in a state where the azimuth information is displayed on the display unit 12, for example, the reader / writer device 200 is contacted with the reader / writer device 200 to perform contactless communication with the access portion. When performing, if the TR antenna 123 is disposed on the upper portion 4a of the second casing 4 (the front surface side of the folded foldable mobile phone 1), the TR antenna 123 approaches the reader / writer device 200. Even in this case, since the geomagnetic sensor 170 is relatively far from the effective area of the electromagnetic wave radiated from the reader / writer device 200, the geomagnetic sensor 170 is strongly based on the electromagnetic wave radiated from the reader / writer device 200. It is relatively insensitive to magnetism.
However, there is always a possibility that the geomagnetic sensor 170 detects erroneous geomagnetism when the user unconsciously or the user intends non-contact communication and brings the mobile phone 1 close to the reader / writer device 200. .

The wireless communication antenna 121 is an antenna for transmitting and receiving information to and from the wireless base station, for example, when making a call or performing mail processing using the mobile phone 1.
The wireless communication unit 101 converts the frequency of a high-frequency communication signal such as call information or mail information received via the wireless communication antenna 121 to the baseband region, and demodulates the baseband signal. The wireless communication unit 101 also modulates call information or mail information in the baseband region, converts the modulated signal into a high-frequency communication signal, and outputs it to the wireless communication antenna 121.

The GPS antenna 122 is an antenna for receiving position information from a GPS artificial satellite.
The GPS signal receiving unit 102 converts a high-frequency signal to a baseband region with respect to a signal including position information received from a GPS artificial satellite (not shown) received by the GPS antenna 122, and performs demodulation processing.

The TR antenna 123 is an antenna for performing contactless communication using electromagnetic waves with the reader / writer device 200 in a contactless communication system such as Suica and transmitting / receiving transaction information.
The TR processing communication unit 103 performs frequency conversion processing on a high frequency signal radiated as an electromagnetic wave from the reader / writer device 200 and received by the TR antenna 123 to the baseband region, and performs demodulation processing on the baseband region signal. The result is sent to a transaction (TR) processing unit 162, which will be described later, constituting a part of the non-contact communication means of the present invention. Alternatively, the TR processing communication unit 103 performs modulation processing to transmit the result processed by the TR processing unit 162 in the mobile phone 1 to the reader / writer device 200, and converts the modulated baseband frequency signal into a high frequency signal. The converted signal is applied to the TR antenna 123 and transmitted to the reader / writer device 200.

  Different frequency bands are used between the radio communication antenna 121 and the radio base station, between the GPS antenna 122 and the GPS artificial satellite, and between the TR antenna 123 and the reader / writer device 200 in order to prevent interference. Communicate with the signal.

The signal processing unit 150 is configured using, for example, a microprocessor (μP). The signal processing unit 150 is an example of the general processing unit 152, the azimuth calculation unit 154, the azimuth information notification unit 156, and the non-contact communication regulation unit of the present invention. It has a transaction (TR) processing restriction unit 158, a case opening / closing detection processing unit 160, and a TR processing unit 162.
In the present embodiment, the total processing unit 152, the direction calculation unit 154 as an example of the direction calculation unit of the present invention, the direction information notification unit 156 as an example of the direction information notification unit of the present invention, a TR processing restriction unit 158, the case opening / closing detection processing unit 160 and the TR processing unit 162 are realized by the program stored in the storage unit 109 performing the processing described below in the arithmetic processing unit (CPU) in the signal processing unit 150. .
The storage unit 109 includes, for example, a program that performs the above-described processes, state data that will be described later, a ROM that stores fixed parameters, and a RAM that is used for temporarily storing (storing) various data. .

An outline of processing contents of the signal processing unit 150 will be described.
For example, based on a user operation instruction from the key input unit 10, the general processing unit 152 performs the following processing, for example.

(1) Call processing When the user performs a dial operation through the key input unit 10 and performs a call operation, for example, the general processing unit 152 detects this, and the voice processing unit 104, the wireless communication unit 101, and the wireless Call processing is performed with the other party that is the call destination via the communication antenna 121. For example, the audio processing unit 104 processes an audio signal input from the microphone 106 and sends it to the other party via the wireless communication unit 101, and outputs the other party's audio signal via the speaker 105.
The general processing unit 152 manages the above processing, and displays information related to the call on the display unit 12 as necessary.

(2) Position Display Processing When the user performs a position display request operation via the key input unit 10, the general processing unit 152 detects it and detects the GPS artificial signal via the GPS signal receiving unit 102 and the GPS antenna 122. The position information of the mobile phone 1 is obtained from the satellite, and the result is displayed in a graphic form on the display unit 12, for example.

(3) Other Processing The general processing unit 152 performs other processing such as remaining amount management processing for the battery unit 111, for example.
Furthermore, the overall processing unit 152 cooperates with the azimuth calculation unit 154, the azimuth information notification unit 156, the TR processing restriction unit 158, the casing opening / closing detection processing unit 160, and / or the TR processing unit 162 to perform the processing described below. Do.

Opening / Closing detection between the first casing and the second casing The casing opening / closing detection processing unit 160 detects the open / closed state of the first casing 3 and the second casing 4.
As described above, the magnetic force sensor 180 disposed on the back surface or the front surface of the first housing upper portion 3a, and the magnet 190 disposed on the outer periphery of the display portion 12 on the back surface or the front surface of the second housing lower portion 4b, When the first housing 3 and the second housing 4 face each other, they are in positions that face each other.
When the first housing 3 and the second housing 4 face each other, the magnetic force sensor 180 and the magnet 190 are substantially opposed to each other, and the magnetic force sensor 180 is affected by the strong magnetic field of the magnet 190. When the magnetic field of the magnet 190 detected by the magnetic force sensor 180 exceeds a predetermined level, the housing open / close detection processing unit 160 is in a state in which the first housing 3 and the second housing 4 face each other or in a substantially face-to-face state. Detect that it is closed.
On the other hand, when the first housing 3 and the second housing 4 are separated from each other, the influence of the magnetic field of the magnet 190 on the magnetic force sensor 180 is reduced. When the magnetic field of the magnet 190 detected by the magnetic force sensor 180 falls below a predetermined level, the housing open / close detection processing unit 160 is in an open state in which the first housing 3 and the second housing 4 are separated from each other. Detect that there is.

  The geomagnetic sensor 170 is disposed substantially at the center of the first housing lower part 3b. The reason is to prevent the magnetic field of the magnet 190 from being affected as much as possible even when the first housing 3 and the second housing 4 face each other. That is, since the geomagnetic sensor 170 is sensitive to a slight magnetic field, it is for avoiding that the orientation is changed by the magnet 190.

Direction calculation and notification of direction information The direction calculation unit 154, which is an example of the direction calculation means of the present invention, calculates the direction based on the geomagnetic detection value detected by the geomagnetic sensor 170.
The azimuth information notifying unit 156, which is an example of the azimuth information notifying unit of the present invention, cooperates with the total processing unit 152 with the azimuth calculation result calculated by the azimuth calculating unit 154. The unit 12 is notified (displayed) as graphic information as exemplified in FIG. FIG. 1A shows an example in which an orientation indicating north is displayed on the display portion 12.
In addition, since the well-known thing can be used for the azimuth | direction calculation method in the azimuth | direction calculation part 154, detailed description is omitted.

Transaction Processing A simple example of performing transaction processing by exchanging information by performing communication processing by non-contact communication using electromagnetic waves radiated from the reader / writer device 200 as an example of the non-contact communication processing of the present invention will be described.
The transaction process means various transaction processes using the mobile phone 1 via the reader / writer device 200. For example, it means a billing process related to issuance of a passport when using Suica, a process related to FeliCa, and the like. Of course, for example, processing for performing deposit processing, stock processing, and the like using the reader / writer device 200 also corresponds to transaction processing.
In the present embodiment, transaction processing means various processing for performing non-contact communication using electromagnetic waves between the mobile phone 1 and the reader / writer device 200 using the non-contact IC card function. .

For example, when the mobile phone 1 is applied to a non-contact communication system such as Suica or FeliCa, the TR antenna 123 in the mobile phone 1 is brought close to the reader / writer device 200 in the non-contact communication system such as Suica or FeliCa.
When an electromagnetic wave is radiated from the reader / writer device 200 and the TR antenna 123 detects the electromagnetic wave, the signal included in the electromagnetic wave that the TR communication unit 103 performs frequency conversion, demodulation processing, and the like as described above. Is sent to the TR processing unit 162.

Hereinafter, an example of an outline of contactless communication between the reader / writer device 200 and the mobile phone 1 housed in an automatic ticket gate installed at a ticket gate of a boarding station when using the Suica function will be described. However, the communication protocol is omitted.
An automatic ticket gate equipped with a reader / writer device 200 is installed at the ticket gate at the boarding station. The electromagnetic wave radiated from the reader / writer device 200 is radiated from the access window.
The electromagnetic waves radiated from the reader / writer device 200 include, for example, data indicating Suica that performs railway passport processing, data indicating a track name, data indicating the name of a boarding station where the ticket gate is located, and the like. Yes.

  The TR processing unit 162 inputs a reception signal from the reader / writer device 200 received via the TR antenna 123 and the TR communication unit 103, and identifies the ticket gate processing for the passport using Suica from the reception signal. To do. Next, the TR processing unit 162 stores the identification number of the foldable mobile phone 1, the available period data, the chargeable amount, etc. stored in advance in the storage unit 109 via the TR communication unit 103. The electromagnetic wave is transmitted from the antenna 123 to the reader / writer device 200 as an electromagnetic wave.

  As a transaction process, the reader / writer device 200 checks the identification number, usable period data, chargeable amount, etc. sent from the cellular phone 1, and if it is a valid and usable folding cellular phone 1, The usage permission signal and the initial ride amount are radiated as electromagnetic waves.

  When the TR processing unit 162 of the mobile phone 1 receives the use permission signal and the initial boarding amount via the TR antenna 123, the data indicating the above-mentioned Suica, the data indicating the track name, and the boarding station name And the permission signal and the initial boarding amount are stored in the storage unit 109. Furthermore, the TR processing unit 162 transmits a confirmation signal indicating that the above processing has been completed to the reader / writer device 200 via the TR communication unit 103 and the TR antenna 123.

When the reader / writer device 200 receives the confirmation signal from the mobile phone 1, the reader / writer device 200 outputs a signal that enables the gate of the automatic ticket gate at the ticket gate to be opened to a ticket gate processing device (not shown). As a result, the gate of the ticket gate opens.
A user who understands that the use of the mobile phone 1 is permitted by opening the gate of the ticket gate, the access window of the reader / writer device 200 provided in the automatic ticket checker with the TR antenna 123 of the mobile phone 1 Move away from.

When the user arrives at the desired disembarkation station, the same operation as described above is performed. However, in that case, it is a getting-off process.
A reader / writer device 200 is also incorporated in an automatic ticket gate installed at the ticket gate of the exit station. The electromagnetic wave radiated from the reader / writer device 200 is radiated from the access window.
The electromagnetic wave radiated from the reader / writer device 200 in the automatic ticket gate at the exit station includes, for example, data indicating Suica that performs rail passport processing, data indicating the line name, and the name of the exit station where the ticket gate is located. Data to show is included.

  The TR processing unit 162 inputs a reception signal from the reader / writer device 200 received via the TR antenna 123 and the TR communication unit 103, and identifies the ticket gate processing for the passport using Suica from the reception signal. To do. Next, the TR processing unit 162 stores the identification number of the mobile phone 1, the available period data, the chargeable amount, and the above processing at the boarding station, which are stored in advance in the storage unit 109. The data indicating the track name, the data indicating the boarding station name, the permission signal, and the initial boarding amount stored in the reader / writer device in the automatic ticket gate at the getting-off station via the TR communication unit 103 and the TR antenna 123 are stored. 200.

  When the reader / writer device 200 in the automatic ticket gate at the getting-off station receives the data and signal from the mobile phone 1, it calculates the charge from the boarding station to the getting-off station and radiates it to the mobile phone 1 as an electromagnetic wave.

The TR processing unit 162 of the mobile phone 1 receives the transmission data from the reader / writer device 200 in the automatic ticket gate at the getting-off station, performs a charging process for the received fee, uses the date / time, route name, boarding station, getting off Store the station and fee in the storage unit 109.
Thereafter, the TR processing unit 162 sends a billing process end signal to the reader / writer device 200 in the automatic ticket gate at the disembarking station.

The reader / writer device 200 built in the automatic ticket gate at the ticket gate at the exit station that has received the billing end signal outputs a signal that allows the gate of the ticket gate to be opened to a ticket gate processing device (not shown). To do. As a result, the gate of the ticket gate opens.
When the gate of the ticket gate is opened, the user of the cellular phone 1 moves the TR antenna 123 of the cellular phone 1 away from the access window of the reader / writer device 200 in the automatic ticket gate of the ticket gate.

Transaction processing restriction processing The transaction (TR) processing restriction unit 158 as an example of the non-contact communication restriction means of the present invention includes an azimuth processing in which at least one of the azimuth calculation unit 154 and the azimuth information notification unit 156 is performed, When transaction processing by non-contact communication using electromagnetic waves radiated from the reader / writer device 200 is not performed at the same time, the respective processing is performed.
However, when the azimuth processing in which at least one of the azimuth calculation unit 154 and the azimuth information notification unit 156 operates and the transaction processing by non-contact communication are performed at the same time, the TR processing restriction unit 158, during the azimuth processing, Regulate transaction processing by contactless communication.

When the mobile phone 1 is brought close to the reader / writer device 200 for transaction processing by non-contact communication, even if the non-contact communication is restricted, the user is unconscious or the user does not contact communication. By positioning the mobile phone 1 in the electromagnetic wave region of the reader / writer device 200 with the intention of transaction processing by the geomagnetic sensor, the geomagnetic sensor 170 can detect erroneous geomagnetism due to the influence of magnetism based on the electromagnetic wave of the reader / writer device 200 There is sex.
For this reason, preferably, a predetermined measure is also taken for the azimuth processing in which one of the azimuth calculation means and the azimuth information notification means is performed.

  The details will be described below with reference to FIG. 4 and FIG.

First Example of Transaction (TR) Processing Regulation FIG. 4 is a flowchart showing a first example of TR processing regulation.
With reference to the flowchart of FIG. 4, the processing of the mobile phone 1 when the azimuth processing in which at least one of the azimuth calculation unit 154 and the azimuth information notification unit 156 operates and the transaction processing by non-contact communication are performed simultaneously will be described. .
In the following description, the case where the integrated processing unit 152 performs control of the processing unit in the signal processing unit 150 is illustrated, and when each processing unit finishes the processing, the integrated processing unit 152 is notified of that, An example is described in which the integrated processing unit 152 performs a control process of starting the processing unit to be operated next. However, for example, when the operation of the azimuth calculation unit 154 is completed, a method of directly starting the azimuth information notification unit 156 that operates next may be used.

Step 1, start of azimuth processing, TR processing regulation processing When the azimuth processing in which at least one of the azimuth calculation unit 154 and the azimuth information notification unit 156 operates is requested by the operation of the key input unit 10 by the user, the comprehensive processing unit 152 discriminates the request and activates the direction calculation unit 154. Thereby, the azimuth | direction process starts.
The total processing unit 152 further activates a TR (transaction) processing restriction unit 158. The activated TR processing restriction unit 158 sets “TR processing restriction by non-contact communication” so as not to substantially perform transaction processing by non-contact communication during the azimuth processing period. As the setting, for example, a flag indicating TR processing restriction by non-contact communication is set to “1” in the state data indicating the operation state of the mobile phone 1 and stored in the storage unit 109.
As described above, regulation of transaction processing by non-contact communication using electromagnetic waves radiated from the reader / writer device 200 is started, and transaction processing by non-contact communication is regulated during the azimuth processing period.

  Note that “substantially does not perform transaction processing by non-contact communication” means that the TR processing communication unit 103 using the TR antenna 123 is not operated and / or the TR processing unit 162 is not operated. This means that even if the TR processing unit 162 is already activated, the transaction processing is interrupted and no further transaction processing operation is performed.

Steps 2, 4, 6, transaction processing request determination The overall processing unit 152 determines whether the azimuth calculation unit 154 or the azimuth information notification unit 156 is operating during the azimuth processing in steps 2, 4, 6. The process which determines the presence or absence of the transaction processing request by contact communication is shown.
As described above, even if the transaction processing by non-contact communication is restricted, the mobile phone 1 is connected to, for example, a reader / writer device in an automatic ticket checker with the intention of transaction processing by non-contact communication unintentionally by the user. When approaching the vicinity of the access window 200, the TR antenna 123 and the TR communication unit 103 respond to the electromagnetic waves of the reader / writer device 200, and it is as if transaction processing is requested. Of course, due to the setting of the transaction processing restriction described above, the TR processing unit 162 does not substantially perform the original processing, but if the mobile phone 1 or the reader / writer device 200 is located within the effective electromagnetic wave region, the geomagnetic sensor 170 The geomagnetism detected by may not be accurate. Therefore, transaction processing by non-contact communication is performed when the mobile phone 1 is located in the electromagnetic wave region of the reader / writer device 200 even during the azimuth processing period in which either the azimuth calculation unit 154 or the azimuth information notification unit 156 is operating. This process is called a request, and the processing described with reference to steps 9 and 10 is performed.

When there is no transaction processing request by non-contact communication during the azimuth processing in the azimuth processing steps 2, 4, and 6 when there is no transaction processing, the following azimuth processing is performed.

Step 3: The geomagnetic data acquisition direction calculation unit 154 acquires the geomagnetic data detected by the geomagnetic sensor 170. The azimuth calculation unit 154 notifies the general processing unit 152 when the acquisition of geomagnetic data is completed.

Step 5, azimuth calculation processing The general processing unit 152 instructs the azimuth calculation unit 154 to continue processing, and the azimuth calculation unit 154 calculates the azimuth of the mobile phone 1 using the acquired geomagnetic data. When the azimuth calculation processing is completed, the azimuth calculation unit 154 notifies the general processing unit 152 of this.

Step 7: The direction information notifying processing unit 152 activates the direction information notifying unit 156. The activated azimuth information notifying unit 156 displays the calculated azimuth information on the display unit 12. As a result, as shown in FIG. 1A, for example, a symbol indicating the north direction is displayed on the display unit 12.
When the direction information notification unit 156 finishes notification of the direction information, the direction information notification unit 156 notifies the general processing unit 152 of the fact.

Step 8: Determination of Continuation Processing The overall processing unit 152 activates the direction calculation unit 154 after a predetermined time has elapsed after notification of the direction information by the direction information notification unit 156.
Thereafter, until the direction calculation unit 154 and the direction information notifying unit 156 are instructed to end the direction processing, the processes of steps 3, 5, and 7 are periodically repeated every predetermined time to determine the direction of the mobile phone 1. Are continuously updated on the display unit 12.

Step 9: Release of transaction processing restriction When the TR processing restriction unit 158 is notified from the general processing unit 152 that the azimuth processing by the azimuth calculation unit 154 and the azimuth information notification unit 156 has been completed, the non-contact performed in step 1 Release transaction processing restrictions by communication.
Thereafter, transaction processing by non-contact communication becomes possible.

Processing in the case where there is a transaction processing request During the above-described azimuth processing, the TR antenna 123 of the mobile phone 1 performs, for example, an automatic ticket gate for transaction processing by non-contact communication in any of steps 2, 4, and 6. When the TR processing unit 162 operates when approaching the access window of the in-flight reader / writer device 200, the TR processing unit 162, in which substantial operation by non-contact communication is restricted, is read from the reader / writer device 200. The general processing unit 152 is notified that the electromagnetic wave has been detected.
As a result, the overall processing unit 152 activates the TR processing restriction unit 158 on the assumption that there is a transaction processing request by non-contact communication. The following processing is performed in cooperation with the TR processing restriction unit 158 and the general processing unit 152.

Step 10: Notification of transaction processing restriction The TR processing restriction unit 158 restricts transaction processing by non-contact communication via the voice processing unit 104 and the speaker 105, and the mobile phone 1 is connected to the electromagnetic wave region of the reader / writer device 200. A warning sound that indicates that the user is restricted from approaching, for example, an audible sound “pipi” is output. From this audible sound, the user recognizes that it is not preferable to bring the mobile phone 1 close to the reader / writer device 200 or the like.
As a result, the user moves the mobile phone 1 away from the electromagnetic wave region of the reader / writer device 200. Thereafter, the user avoids bringing the mobile phone 1 close to the reader / writer device 200.

Step 11, Treatment for Direction Processing In the above case, it is true that the mobile phone 1 is located in the electromagnetic wave region of the reader / writer device 200 in the automatic ticket gate, for example, so that the geomagnetism detected by the geomagnetic sensor 170 is accurate. It may not be. Therefore, the case where the direction information currently displayed or displayed on the display part 12 is inaccurate is assumed.
In order to indicate this inaccurate geomagnetic notification state, the TR process restricting unit 158 performs, for example, any of the following notification processes.
(1) The direction information displayed on the display unit 12 is blinked to visually warn the user of the mobile phone 1.
(2) The azimuth information displayed on the display unit 12 is slightly darkened (decreasing brightness).
(3) Display fixed azimuth information, for example, azimuth information facing north, on the display unit 12.
In addition to the warning sound described above, the user understands that the azimuth information is not accurate because the azimuth information changes as described above.

In such a situation, the user can perform calibration for orientation processing, for example.
As the calibration, for example, the mobile phone 1 is moved away from the current position and the azimuth process is resumed.
After the above process, the general processing unit 152 restarts the process from step 2 or step 3, for example.

Strong Warning In addition, in situations where the mobile phone 1 approaches the electromagnetic wave region of the reader / writer device 200 frequently or repeatedly, the TR processing restriction unit 158 generates a warning sound stronger than the warning sound described above. Can be output.
Such a strong warning sound is, for example, an audible sound called “Pippy” with a high volume, an audible sound called “Pippy” with a higher frequency, or a “Peepy” sound with a higher volume and a higher frequency. .
“Frequently” is defined in relation to the azimuth processing by the azimuth calculation unit 154 and the azimuth information notification unit 156. For example, the mobile phone 1 is connected to the reader / writer device 200 twice or more within 10 minutes. When approaching the electromagnetic field. “Repeat” means, for example, a case where the mobile phone 1 approaches the electromagnetic wave region of the reader / writer device 200 repeatedly within one minute.

  As described above, the transaction process is restricted during the period of the azimuth process in which at least one of the azimuth calculation unit 154 and the azimuth information notification unit 156 is operating.

Forced release of transaction processing regulations (1)
The mobile phone 1 is provided with a “transaction processing request by non-contact communication” button on the side surface of the key input unit 10 or the first housing 3 or the second housing 4 of the mobile phone 1 (not shown), for example. 1) When the “transaction processing request by non-contact communication” button is pressed, transaction processing by non-contact communication is performed regardless of the azimuth processing period in which either the azimuth calculation unit 154 or the azimuth information notification unit 156 is operating. Can be forcibly performed. In that case, when the azimuth processing is restricted and the azimuth processing is temporarily stopped and the transaction processing by non-contact communication is completed, the azimuth processing by the azimuth calculation unit 154 and the azimuth information notification unit 156 is resumed.

Forced release of transaction processing regulations (2)
Since the foldable mobile phone 1 described above cannot use the key input unit 10 and the display unit 12 when the casing is closed, the direction calculating unit 154 and the direction information notifying unit 156 are usually used. No orientation processing is performed.
Therefore, when the case open / close detection processing unit 160 detects that the first case 3 and the second case 4 face each other and the case is closed, the general processing unit 152 includes the azimuth calculation unit 154 and The direction information notification unit 156 is not operated. Alternatively, when the azimuth processing is requested, when the casing opening / closing detection processing unit 160 detects that the first casing 3 and the second casing 4 face each other and the casing is closed, the azimuth processing Can be forcibly terminated.
In that case, the integrated processing unit 152 forcibly stops the azimuth calculation unit 154 and / or the azimuth information notification unit 156, for example. Thereafter, the integrated processing unit 152 causes the display unit 12 to display a standby screen, for example.
As described above, when the user closes the case of the foldable mobile phone 1 during the azimuth processing period, the azimuth processing is ended (paused) and transaction processing by non-contact communication is possible. The transaction processing restriction by non-contact communication may be forcibly released by closing the casing.

Forced release of transaction processing regulations (3)
Further, for example, in spite of the strong warning, when the user brings the folding mobile phone 1 close to the electromagnetic wave region of the reader / writer device 200 in the automatic ticket gate, for example, the user does not perform the direction processing. Presume that you want to prioritize transaction processing by contact communication. Also in this case, transaction processing by non-contact communication can be forcibly performed. In that case, the azimuth | direction process is controlled. In this case, the period during which the foldable mobile phone 1 detects the electromagnetic wave from the reader / writer device 200 is longer than a predetermined time, or the approach distance between the mobile phone 1 and the reader / writer device 200 is within a predetermined distance. The process may be performed when the is detected.

Second Example of Transaction (TR) Processing Restriction FIG. 5 is a flowchart showing a second example of transaction processing restriction.
In the process described with reference to FIG. 4, when performing the azimuth process continuously, the process of steps 10 and 11 is performed when the transaction process by non-contact communication is requested, and the process of step 2 or step 3 is performed. The case of resuming from is described.
The process illustrated in FIG. 5 illustrates an example of a period during which the azimuth process is performed only when the azimuth process is requested and / or a process with less burden on the signal processing unit 150 in the continuous azimuth process.
The processing in steps 21 to 29 is basically the same as the processing in steps 1 to 9 in FIG.

Step 21 and Activation of Direction Processing The processing is substantially the same as the processing in Step 1 in FIG.

Steps 22, 24, and 26, transaction processing request determination are substantially the same as steps 2, 4, and 6 in FIG. 4.

When there is no transaction processing by non-contact communication during the azimuth processing in the azimuth processing steps 22, 24, and 26 when there is no transaction processing request , the following azimuth processing is performed.
Acquisition of geomagnetic data in step 23, calculation of azimuth in step 25, and notification of azimuth information in step 27 are the same as the processing in steps 3, 5, 7, and 8 in FIG.

Step 30, notify transaction processing restriction status (1)
In step 22, as described with reference to FIG. 4, when the TR processing unit 162 detects the electromagnetic wave of the reader / writer device 200 in the automatic ticket gate, for example, via the TR antenna 123 and the TR communication unit 103. The TR processing unit 162, which presumes that there is a transaction processing request and whose substantial operation is restricted, notifies the general processing unit 152 that the electromagnetic wave of the reader / writer device 200 has been detected.
As a result, the overall processing unit 152 activates the TR processing restriction unit 158.
In order to notify the user that the transaction processing request is restricted during the azimuth processing period, the TR processing restriction unit 158 performs the following processing, for example, in the same manner as the processing in step 10 of FIG.
The TR processing restriction unit 158 is restricted in transaction processing via the sound processing unit 104 and the speaker 105, and it is meaningless to bring the foldable mobile phone 1 close to an electromagnetic wave region such as the reader / writer device 200. A warning sound indicating that, for example, an audible sound “Pippy” is output. From this audible sound, the user recognizes that it is not preferable that the foldable mobile phone 1 is brought close to the reader / writer device 200 or the like.
As a result, the user moves the foldable mobile phone 1 away from the electromagnetic wave region of the reader / writer device 200. Thereafter, the user avoids bringing the foldable mobile phone 1 close to the reader / writer device 200.

At this time, the azimuth calculation unit 154 has not obtained the geomagnetic data detected by the geomagnetic sensor 170. Therefore, the orientation information is not substantially affected by the electromagnetic waves from the reader / writer device 200. Therefore, the TR processing restriction unit 158 notifies the general processing unit 152 that the processing is resumed from the processing in step 23.
The general processing unit 152 activates the azimuth calculation unit 154 and instructs acquisition of geomagnetic data.

Step 31, Notify transaction processing restriction status (2)
In step 24, as described with reference to FIG. 4, when the TR processing unit 162 detects an electromagnetic wave from the reader / writer device 200, it is presumed that there is a transaction processing request by non-contact communication, and a substantial operation is performed. The TR processing unit 162 that is regulated to notify the integrated processing unit 152 that the electromagnetic wave from the reader / writer device 200 has been detected.
As a result, the overall processing unit 152 activates the TR processing restriction unit 158.
The TR process restricting unit 158 performs the same process as the process of step 30 in order to notify the user that the transaction process request is based on the regulated non-contact communication during the azimuth process period. As a result, the warning sound described above, for example, an audible sound “Pippy” is output.
At this time, the azimuth calculation unit 154 has already acquired the geomagnetic data detected by the geomagnetic sensor 170. Therefore, there is a high possibility that the obtained geomagnetic data is not affected by the electromagnetic wave from the reader / writer device 200. Therefore, the TR process restricting unit 158 notifies the general processing unit 152 that the process is resumed from the process of Step 25.
The general processing unit 152 activates the azimuth calculation unit 155 and instructs to calculate the azimuth from the geomagnetic data detected by the geomagnetic sensor 170.

Step 32, Notify transaction processing restriction status (3)
In step 26, as described with reference to FIG. 4, when the TR processing unit 162 detects an electromagnetic wave from the reader / writer device 200, it is presumed that there is a transaction processing request by non-contact communication, and a substantial operation is performed. The TR processing unit 162 that is regulated to notify the integrated processing unit 152 that the electromagnetic wave from the reader / writer device 200 has been detected.
As a result, the overall processing unit 152 activates the TR processing restriction unit 158.
The TR process restricting unit 158 performs the same process as the process of step 30 in order to notify the user that the transaction process request is based on the regulated non-contact communication during the azimuth process period. As a result, the warning sound described above, for example, an audible sound “Pippy” is output.
At this time, the direction calculation unit 154 has already obtained the direction based on the geomagnetic data detected by the geomagnetic sensor 170. Therefore, there is a high possibility that the calculated orientation is not affected by the electromagnetic wave from the reader / writer device 200. Therefore, the TR processing restriction unit 158 notifies the general processing unit 152 that the processing is resumed from the processing of step 27.
The general processing unit 152 activates the azimuth information notifying unit 156 to instruct azimuth information.

Step 28, Determination of Continuation of Direction Processing After direction notification in step 28, the overall processing unit 152 checks whether or not the direction processing is continued, and returns to the processing of step 22 or step 23 if it is continued. .
When the azimuth processing is not performed continuously, the general processing unit 152 activates the TR processing restriction unit 158. The TR processing restriction unit 158 cancels the transaction processing restriction by non-contact communication. Thereafter, the TR processing unit 162 can perform transaction processing by non-contact communication.

Forcible release of transaction processing restriction The above-described forcible release of transaction processing restriction by non-contact communication (1), (2), (3) can be applied to this embodiment.

As illustrated in FIG. 6, the display unit 12 is rotated by rotating the display unit 12 even when the first housing 3 and the second housing 4 face each other in the foldable mobile phone according to the second embodiment .
