Description

  The present invention relates to a portable terminal device.

  In recent years, mobile terminal devices such as mobile phones and PDAs (Personal Digital Assistants) have been proposed that have one or more communication functions. (For example, refer to Patent Document 1). Among them, there has been proposed a foldable or slide-type mobile terminal device that controls ON and OFF of a display unit according to an open / close state. Hereinafter, an example of a data transmission / reception operation by a foldable portable terminal device having an RFID (Radio Frequency IDentification) communication function will be described with reference to FIGS. The RFID communication is data transmission / reception by electromagnetic induction of electromagnetic waves.

4 and 5 are a side sectional view and a plan view showing an example of a foldable portable terminal phone in which an RFID antenna portion is provided in the upper housing. The mobile phone 100 includes an upper housing 110 and a lower housing 120 each having a substantially rectangular parallelepiped shape, and a hinge 130 that connects them.
Hereinafter, when the mobile phone 100 is folded by moving the upper housing 110 and the lower housing 120 close to each other by moving the hinge 130 as a rotation axis, the upper housing 110 and the lower housing 120 are moved. The surfaces facing each other are referred to as the front surface, and the surface opposite to the surface is referred to as the back surface.

  The upper casing 110 is provided with a display unit 111 made of LCD (Liquid Crystal Display), organic EL (Electro Luminescence), or the like on the surface. In addition, an RFID antenna unit 112 is provided inside the upper housing 110 on the back side. An antenna center mark 112 a is provided at a substantially central portion of the surface of the RFID antenna portion 112. Further, in the central portion inside the upper housing 110, a substrate 115 on which an RFID control unit 113 for controlling the RFID antenna unit 112 and a magnetic sensor 114 such as a Hall IC or MR sensor are mounted, and the substrate 115 and the RFID antenna. An RFID connection unit 116 that connects the unit 112 is provided. Here, the magnetic sensor 114 is provided on the side of the other side opposite to the one side connected to the hinge 130 of the upper housing 110.

  On the other hand, the lower casing 120 is provided with an operation input unit 121 including numeric keys, numeric keys, jog shuttle, and the like on the surface. Further, inside the lower housing 120, a magnet 122 is provided on the surface side in the vicinity of the other side opposite to the one side connected to the hinge 130 of the lower housing 120, and the speaker 123 on the back side. Is provided.

  In such a cellular phone 100, the open / close state is detected by the magnetic sensor 114 and the magnet 122 functioning as an environment detection sensor (see, for example, Patent Document 2). That is, in the closed state in which the upper housing 110 and the lower housing 120 of the mobile phone 100 are close to each other, the magnetic sensor 14 detects the magnetic force from the surrounding environment because it is close to the magnet 122. In such a case, the magnetic sensor 114 determines that the mobile phone 100 is in a closed state.

  6 and 7 are a cross-sectional view and a plan view schematically showing an example of a foldable mobile phone in which an RFID antenna portion is provided in the lower housing. The cellular phone 200 includes an upper casing 210 and a lower casing 220 each having a substantially rectangular parallelepiped shape, and a hinge 230 that connects them.

  The upper casing 210 is provided with a display unit 211 made of an LCD, an organic EL, or the like on the surface side. Further, the lower housing 220 is provided with an operation input unit 221 on the front surface side and a speaker 222 and an RFID antenna unit 223 on the back surface side. An antenna center mark 223a is provided at a substantially central portion of the surface of the RFID antenna portion 223. In addition, a substrate 225 on which an RFID control unit 224 that controls the RFID antenna unit 223 is mounted and an RFID connection unit 226 that connects the substrate 225 to the RFID antenna unit 223 are provided inside the lower housing 220. ing.

  When performing RFID communication between the mobile phone 100 and the mobile phone 200 as described above, as shown in FIG. 8, the RFID antenna portions 112 and 223 are brought close to each other so that the antenna center marks 112a and 223a are aligned. . At this time, it is desirable to bring them closer to each other (for example, about 10 mm or less). Thereby, data can be transmitted and received stably.

However, when the mobile terminal devices are brought close to each other, one mobile terminal device includes an environment detection sensor such as a foldable mobile phone 100 as described above, and the other mobile terminal device generates a magnetic force. If the generated member is provided, the environment detection sensor may detect the magnetic force of the member depending on the arrangement of the members.
Since the magnetic sensor used as an environment detection sensor is composed of a circuit device using the Hall effect, it reacts not only to the magnetic force emitted from the opening / closing detection magnet but also to the magnetic force emitted from a speaker or the like. May end up. Therefore, as shown in FIG. 5, when the RFID antenna unit 112 of the mobile phone 100 and the RFID antenna unit 223 of the mobile phone 200 are brought close to each other, the magnetic sensor 114 of the mobile phone 100 and the speaker 222 of the mobile phone 200 are also brought close to each other. Therefore, the magnetic sensor 114 may detect the magnetic force output from the speaker 222.

  When the environment detection sensor detects the magnetic force from the surrounding environment, the device itself erroneously recognizes that it is in the closed state even if it is in the open state. Usually, in a folding portable terminal device, the display unit is turned off when the device is in the closed state. If the device itself is mistakenly considered to be in the closed state, the display unit may be turned off even during communication. In such a case, the communicating user determines whether or not the data transmission has been completed based on the message displayed on the front surface, and therefore confirms whether or not the communication has been completed when the display is turned off. In some cases, communication itself was interrupted.

  Accordingly, an object of the present invention is to provide a mobile terminal device, a control method for the mobile terminal device, and a control program for the mobile terminal device that are not affected by the environment around the device during communication.

  In order to solve the above-described problems, a mobile terminal device according to the present invention is based on a communication unit that communicates with another device, a sensor that detects an environment in which the device is placed, and an output of the sensor. And a control unit that controls the state of the own device, and the control unit maintains the state of the own device regardless of the output of the sensor when the communication unit is communicating. .

A control method of a portable terminal device including a control unit for controlling, wherein the state of the own device is maintained regardless of the output of the sensor when the communication unit is communicating.

  In addition, the control program for the portable terminal device according to the present invention includes a communication unit that communicates with other devices, a sensor that detects an environment in which the device is placed, and the state of the device based on the output of the sensor.

<Configuration of mobile phone>
As shown in FIG. 2, the mobile phone 2 according to the present embodiment includes a foldable mobile phone, and includes an RFID control unit 21, a speaker unit 22, an open / close determination unit 23, and a radio unit 24. A storage unit 25, an operation input unit 26, a display unit 27, and a control unit 28.

  The RFID control unit 21 includes a circuit device that controls RFID communication, and performs RFID communication with other devices based on instructions from the control unit 28. Such an RFID control unit 21 is connected to the RFID antenna 21a via the RFID connection unit 21b.

  The speaker unit 22 includes a known speaker device, and outputs sound based on an instruction from the control unit 28.

  The open / close determination unit 23 includes a circuit device that determines the open / close state of the mobile phone 2 based on the detection result of the connected magnetic sensor 23a. The magnetic sensor 23a functioning as an environment detection sensor is, for example, one of the two casings each having one side connected by a hinge, such as the mobile phone 100 shown in FIGS. It is arrange | positioned in the other side vicinity. On the other hand, the magnet paired with the magnetic sensor 23a is disposed near the other side of the other casing. Thereby, when the mobile phone 2 is in the closed state, the magnetic sensor 23a detects the magnetic force from the surrounding environment in order to approach the magnet. When the magnetic force is detected from the environment around the mobile phone 2 in this way, the open / close determination unit 23 determines that the mobile phone 2 is in the closed state. The open / close determination unit 23 determines that the mobile phone 2 is in the open state regardless of the detection result from the magnetic sensor 23a when the RFID control unit 21 performs RFID communication. Such a determination result is output to the control unit 28.

  The radio unit 24 is a circuit device that implements voice communication and data communication by exchanging various signals with the base station via the antenna 24 a based on an instruction from the control unit 28.

  The storage unit 25 includes a known storage device such as a volatile memory or a nonvolatile memory. The storage unit 25 stores data necessary for the operation of the mobile phone 2 including the operation program of the control unit 28, and these data are exchanged with the control unit 28.

  The operation input unit 26 includes a known input device such as a numeric keypad, a jog shuttle, or a keyboard. The input from the user detected by the operation input unit 26 is sent to the control unit 28.

  The display unit 27 includes a known display device such as an LCD (Liquid Crystal Display), an organic EL (Electro Luminescence), or an FED (Field Emission Display). Such a display unit 27 performs various displays based on instructions from the control unit 28. Further, the display unit 27 is turned off by an instruction from the control unit 28 when the mobile terminal device 2 is in the closed state.

  The control unit 28 includes a microprocessor such as a CPU and its peripheral circuits, and reads and executes a control program stored in the storage unit 25. As a result, the hardware and its control program cooperate to implement each function of the mobile phone 2 such as a call process, a data communication process, an RFID communication process, and an open / close detection process. In the present embodiment, a signal (hereinafter referred to as a communication signal) is output to the open / close determination unit 23 during RFID communication.

<RFID communication processing operation>
Next, an RFID communication processing operation by the mobile phone 2 according to the present embodiment will be described with reference to FIG.

  When performing RFID communication with another device, the user first opens the mobile phone 2. Then, since the magnetic sensor 23a is separated from the paired magnets, it does not detect the magnetic force. Thereby, the open / close determination unit 23 determines that the mobile phone 2 is in the open state (step S1). This determination result is output to the control unit 28.

  When the mobile phone 2 is in the open state, the user inputs that the RFID communication is performed via the operation input unit 26. When the operation input unit 26 detects this operation input (step S2: YES), the control unit 28 causes the RFID control unit 21 to output a carrier wave from the RFID antenna 21a (step S3). At this time, the control unit 28 may cause the display unit 27 to display a message requesting that the RFID antenna 21a be brought close to the RFID antenna of the counterpart device.

  When the carrier wave is output, the control unit 28 transmits a communication signal indicating that RFID communication is being performed to the open / close determination unit 23. Then, the open / close determination unit 23 forcibly determines that the mobile phone 2 is in the open state regardless of the detection result from the magnetic sensor 23a (step S3), and a signal (hereinafter, referred to as the open state). An open signal is sent to the control unit 28 (step S5).

  Further, when outputting the carrier wave, the RFID control unit 21 confirms whether or not mutual authentication with the partner apparatus that performs RFID communication is possible (step S6).

  When mutual authentication has failed (step S6: NO), the control unit 28 returns to the process of step S5. At this time, the control unit 18 causes the display unit 27 to display a message requesting that the RFID antenna 21a be brought closer to the RFID antenna of the counterpart device, or to connect the RFID antenna 21a from the speaker unit 22 to the RFID antenna of the counterpart device. Further, an alarm sound requesting close proximity may be output.

  If mutual authentication is successful (step S5: YES), the RFID control unit 21 starts RFID communication with the counterpart device (step S6).

  During such RFID communication, when the magnetic sensor detects a magnetic force from, for example, a communication partner microphone or a magnet for open / close detection, the open / close determination unit 23 receives a communication signal from the control unit 28. Regardless of the detection result from the magnetic sensor 23a, the mobile phone 2 is determined to be in the open state, and the open signal is continuously output to the control unit 28. Then, the control unit 28 maintains the current state of the own device. Thereby, the display state of the display unit 27 and the communication state by the RFID control unit 21 are maintained, and the display unit 27 can be turned off or RFID communication can be stopped. For this reason, since the user can confirm the message regarding whether or not the RFID communication displayed on the display unit 27 is completed, the RFID communication can be reliably performed.

  When the RFID communication ends (step S8: YES), the control unit 28 sends a signal indicating that the RFID communication is ended (hereinafter referred to as a communication end signal) to the open / close determination unit 23. When receiving the communication end signal, the open / close determining unit 23 cancels the forced output of the open signal (step S9), and thereafter determines the open / closed state of the mobile phone 2 based on the detection result of the magnetic sensor 23a. .

  As described above, according to the present embodiment, during RFID communication, the communication state of RFID communication and the display state of the display unit 27 are maintained regardless of the output of the magnetic sensor 23a. Can be prevented from being influenced by the surrounding environment.

  In the present embodiment, the case where the open / close determining unit 23 is configured by a circuit device made up of hardware resources has been described as an example. However, the open / closed state 23 is obtained when the control unit 28 reads the operation program to And a function unit realized by cooperation of software and software.

  In this embodiment, the case where the present invention is applied to a foldable mobile phone as an example of a mobile terminal device has been described. However, the present invention is not limited to a mobile phone as long as it is a foldable terminal device. It can be applied to various portable terminal devices such as portable music players.

  In this embodiment, the case where the present invention is applied to a foldable portable terminal device has been described as an example. However, it goes without saying that the present invention can also be applied to a slide-type or cover-type portable terminal device.

  In this embodiment, the case of communicating with another device by RFID communication has been described as an example. However, the communication is not limited to RFID communication, and may be applied to, for example, various communication such as IR communication. Can do.

  In this embodiment, magnetic force has been described as an example of an environment that affects communication. However, for example, various states may be used if the communication state or display state of mobile phone 2 is affected, such as an incoming call or mail reception. Can be applied.

  In the present embodiment, the display unit 27 is not turned off when the magnetic sensor 23a detects a magnetic force. However, communication itself such as RFID communication may not be turned off. Thereby, even if the display unit 27 is turned off, the communication state can be maintained, so that the communication can be reliably performed.

  The present invention can be applied to a portable terminal device having an RFID communication function, such as a mobile phone, a PDA, a PC (Personal Computer), and a portable music player.
