First Embodiment Referring to FIG. 1, mobile communication terminal 10 of the first embodiment includes a key input device 26. When a call operation is performed by the key input device 26, the CPU 22 controls the radio communication circuit 14 corresponding to the CDMA system and outputs a call signal. The output call signal is emitted from the antenna 12 and transmitted to the telephone of the other party via a mobile communication network including a base station. When the other party performs an incoming call operation, a call ready state is established.

  When a call end operation is performed by the key input device 26 after the transition to the call ready state, the CPU 22 controls the wireless communication circuit 14 to transmit a call end signal to the other party. After transmitting the call end signal, the CPU 22 ends the call process. Also when the call end signal is received from the call partner first, the CPU 22 ends the call process. Also, the CPU 22 ends the call process when a call end signal is received from the mobile communication network regardless of the call partner.

  When a call signal from a call partner is captured by the antenna 12 while the entire system is activated, the wireless communication circuit 14 notifies the CPU 22 of an incoming call. The CPU 22 outputs the caller information described in the incoming call notification from the main LCD monitor 32, and outputs a ring tone from an incoming call notification speaker (not shown). When an incoming call operation is performed by the key input device 26, a call ready state is established.

  In the call ready state, the following processing is executed. The modulated audio signal (high frequency signal) sent from the other party is captured by the antenna 12. The captured modulated audio signal is subjected to demodulation processing and decoding processing by the wireless communication circuit 14. The received voice signal thus obtained is output from the speaker 18.

  The transmitted voice signal captured by the microphone 16 is subjected to encoding processing and modulation processing by the wireless communication circuit 14. The modulated audio signal generated thereby is transmitted to the other party using the antenna 12 as described above.

  The Felica circuit 24 is a short-range wireless communication circuit configured based on a non-contact IC card technology called “FeliCa” (registered trademark), and includes an antenna 24a for performing short-range wireless communication. Near field communication is performed by bringing the antenna 24a and a reader / writer (not shown) close to each other while the Felica mode is selected by the key input device 26.

  The magnetic sensor 28 detects the magnetism of the magnetic force 30 and outputs a value of 0 to 255 depending on the detected magnetic intensity.

  2A to 2C, portable communication terminal 10 has cases C1 and C2 each formed in a plate shape. The thickness of case C1 and case C2 is substantially the same. The Felica circuit 24 is built in the case C2 so that the antenna 24a has good reception sensitivity on the lower surface of the case C2. The key input device 26 is attached to the case C1 and the case C2 so that the operation key group is exposed on the upper surface of the case C1 and the upper surface of the case C2. The magnetic sensor 28 is built in the case C2. The magnet 30 is built in the case C1 so as to be closest to the magnetic sensor 28 in the state of FIG. The main LCD monitor 32 is attached to the case C1 so that the monitor screen is exposed on the upper surface of the case C1.

  That is, the main LCD monitor 32 is attached to the upper surface of the case C1, and the magnet 30 is built in the case C1. The magnetic sensor 28 is built in the case C2, and the Felica circuit 24 is built in the case C2. The key input device 26 has an operation key group attached to the upper surfaces of the case C1 and the case C2.

  The slide mechanisms SL are provided at both ends in the width direction of the lower surface of the case C1 and at both ends in the width direction of the upper surface of the case C2. That is, the case C1 can slide in the length direction of the case C2 while being stacked on the case C2. The slide mechanism SL includes a slide assist mechanism (not shown) that assists the slide with a spring mechanism.

The magnetic sensor 28 outputs 255 as the maximum value in the state shown in FIG. 2A, and outputs 0 as the minimum value in the states shown in FIGS. 2B and 2C. When the output value of the magnetic sensor 28 slides from FIG. 2A to FIG. 2B and FIG. 2C, the output value decreases according to the slide amount. That is, in the closed state shown in FIG. 2A, the magnetic sensor 28 outputs the maximum value, and FIG.
In the open state shown in B) and FIG. 2C, the magnetic sensor 28 outputs a minimum value.

  The CPU 22 performs switching processing between the open state and the closed state by comparing the output value of the magnetic force sensor 28 with a threshold value. The threshold value is an output value of the magnetic force sensor 28 when the antenna 24a is slid to a limit position where the position of the antenna 24a falls within the display range of the main LCD monitor 32. For example, when the threshold value is 128, the output value of the magnetic sensor 28 is closed from 255 to 128, which is the maximum value, and the output value of the magnetic sensor 28 is open from 127 to 0, which is the minimum value. .

  As described above, the Felica circuit 24 is built in the case C2 so that the antenna 24a has good reception sensitivity on the lower surface of the case C2. Accordingly, short-range wireless communication using the Felica circuit 24 is performed by bringing the lower surface of the case C2 close to the reader / writer. However, the user cannot recognize the position of the antenna 24a when the lower surface of the case C2 is brought close to the reader / writer.

  Therefore, when short-range wireless communication using the Felica circuit 24 is performed, the position of the antenna 24a built in the case C2 is displayed on the main LCD 32 attached to the upper surface of the case C1.

  Specifically, referring to FIGS. 2 (A) to 2 (C) and FIGS. 3 (A) to 3 (C), assist mark 36 is positioned on antenna 24a with respect to main LCD monitor 32, or Felica. The position of the antenna 24a with respect to the case C2 in which the circuit 24 is built is shown. FIG. 38 schematically shows an operation key group of the key input device 26 attached to the upper surface of the case C2.

In the closed state shown in FIG. 2A, the back side of the lower surface of the case C2 in which the reception sensitivity of the antenna 24a is ensured is regarded as the upper surface of the case C1 to which the main LCD monitor 32 is attached. Therefore, the display range of the main LCD monitor 32 includes the position of the antenna 24a. Therefore, the main LCD monitor 32 displays the assist mark 36 at the position of the antenna 24 a with respect to the display range of the main LCD monitor 32. Here, a display example displayed on the main LCD monitor 32 in the closed state is shown in FIG.

  That is, the antenna 24 a is present behind the assist mark 36 displayed on the main LCD monitor 32. Then, the user touches the surface where the reception sensitivity of the antenna 24a is satisfactorily secured, for example, the lower surface of the case C2, so that the position of the assist mark 36 displayed on the main LCD monitor 32 and the reader / writer overlap. What is necessary is just to make it close to a reader / writer.

  In the open state shown in FIGS. 2B and 2C, the back side surface of the lower surface of the case C2 in which the reception sensitivity of the antenna 24a is ensured is the upper surface of the case C2. Therefore, the display range of the main LCD monitor 32 does not include the position of the antenna 24a. Therefore, the main LCD monitor 32 displays a schematic diagram 38 of the upper surface of the case C2, and further displays the assist mark 36 at the position of the antenna 24a with respect to the upper surface of the case C2. Here, a display example displayed on the main LCD monitor 32 in the open state is shown in FIG.

  That is, the antenna 24a is present on the back side of the upper surface of the case C2 corresponding to the schematic diagram 38 displayed on the main LCD monitor 32. The user has good reception sensitivity of the antenna 24a so that the position indicated by the assist mark 36 and the reader / writer overlap each other on the upper surface of the case C2 corresponding to the schematic diagram 38 displayed on the main LCD monitor 32. The secured surface, for example, the lower surface of the case C2 may be brought close to the reader / writer.

  Further, the CPU 22 detects a change in the position of the antenna 24a relative to the main LCD monitor 32 from the output value of the magnetic sensor 28 when the output value of the magnetic sensor 28 changes in the closed state, and the assist mark 36 is based on the detection result. Move. For example, when the value of the magnetic sensor 28 continuously changes, the position of the antenna 24a with respect to the main LCD monitor 32 changes in the same manner, so that the assist mark 36 is displayed on the main LCD monitor 32 as an animation.

  That is, when the CPU 22 slides from the state of FIG. 2 (A) to the state of FIG. 2 (C), the closed state is drawn with a dotted line as in the display example shown in FIG. 3 (C). The position is moved stepwise from the position of the assist mark 36 to the position of the assist mark 36 drawn with a solid line. Then, the user can adjust the reception sensitivity of the antenna 24a so that the position of the assist mark 36 displayed on the main LCD monitor 32 overlaps the reader / writer corresponding to the position of the assist mark 36 moved in stages. A well secured surface such as the lower surface of the case C2 may be brought close to the reader / writer.

The CPU 22 executes a plurality of tasks including the Felica mode control task shown in FIG. 4 and the assist control task shown in FIG. 5 in parallel. The control program corresponding to these tasks is stored in the flash memory 20, and the assist mark 36 and the image data in the schematic diagram 38 shown in FIGS. 3A to 3C are stored in the flash memory 20. The data is read from the flash memory 20 in accordance with the assist control task process.

First, the Felica mode control task will be described. Referring to FIG. 4, in step S <b> 1, it is determined whether or not a Felica mode activation operation has been performed on key input device 26. If “YES” here, in order to make the Felica circuit 24 in a state capable of being turned on, the process proceeds to a step S3 to activate an assist control task. If “NO” here, the process returns to the step S 1, and the process of the step S 1 is repeated until the Felica mode starting operation is performed on the key input device 26. Subsequently, in step S5, the Felica circuit 24 is turned on so that near field communication using the Felica circuit 24 can be performed. Subsequently, in step S7, it is determined whether or not a Felica mode stop operation has been performed on the key input device 26. If “NO” here, the process of step S 7 is repeated until the Felica mode stop operation is performed on the key input device 26. If "YES" here, the process proceeds to step S9 to end the short-range wireless communication using the Felica circuit 24, and the Felica circuit 24 is turned off. Subsequently, in step S11, since the short-range wireless communication using the Felica circuit 24 has been completed, the assist control task is terminated, and the process returns to step S1.

Next, the assist control task will be described.
Referring to FIG. 5, in step S13, it is determined whether or not the output value of magnetic sensor 28 is equal to or greater than a threshold value. If “NO” here, the output value of the magnetic sensor 28 is equal to or smaller than the threshold value, so that the open state shown in FIGS. 2B and 2C is obtained. In step S15, the main LCD monitor 32 displays a schematic diagram 38 of the upper surface of the case C2, and displays the assist mark 36 at the position of the antenna 24a with respect to the upper surface of the case C2. Subsequently, in step S17, it is determined whether or not the output value of the magnetic sensor 28 has changed. If “YES” here, the process returns to the step S13 in order to determine again whether or not the output of the magnetic sensor 28 is equal to or greater than the threshold value. If “NO” here, the process returns to the step S15 to display the schematic diagram 38 on the upper surface of the case C2 on the main LCD monitor 32 and continue to display the assist mark 36 at the position of the antenna 24a with respect to the upper surface of the case C2.

  If YES in step S13, the output value of the magnetic sensor 28 is equal to or greater than the threshold value, and the closed state shown in FIG. In step S 19, the position of the Felica circuit 24 relative to the main LCD monitor 32 is specified from the output value of the magnetic sensor 28. Subsequently, in step S21, the assist mark 36 is displayed on the main LCD monitor 32 at the position of the Felica circuit 24 specified in step S19.

  Subsequently, in step S23, it is determined whether or not the output value of the magnetic sensor 28 has changed. If “YES” here, the process returns to the step S13 in order to determine again whether or not the output of the magnetic sensor 28 is equal to or greater than the threshold value. If “NO” here, the process returns to the step S19 to repeat the processes of the steps S19 to S21, so that the assist mark 36 is continuously displayed at the position of the Felica circuit 24 specified in the step S19.

  Further, when the case C1 slides with respect to the case C2 in the closed state, the processes of step S13 and steps S19 to S23 are repeated. Therefore, the position of the antenna 24a with respect to the main LCD monitor 32 changes in the same manner, so that the assist mark 36 is displayed on the main LCD monitor 32 as an animation.

  As can be seen from the above description, each of the case C1 and the case C2 is formed in a plate shape. The main LCD monitor 32 is attached to the upper surface of the case C1. The Felica circuit 24 and the antenna 24a are built in the case C2. The slide mechanism SL connects the case C1 and the case C2 so that the state of the case C1 with respect to the case C2 can be changed. The magnetic sensor 28 detects the state of the case C1 with respect to the case C2. The process of step S13 determines whether or not the antenna 24a is included in the display range of the main LCD monitor 32. If the determination in step S13 is YES, the process in step S15 causes the main LCD monitor 32 to display an assist mark 36 indicating the position of the antenna 24a with respect to the main LCD monitor 32. If the determination in step S13 is NO, the process in step S21 causes the main LCD monitor 32 to display a schematic diagram 38 on the upper surface of the case C2, and further displays the assist mark 36 at the position of the antenna 24a with respect to the upper surface of the case C2. Display. Therefore, when the Felica circuit 24 performs short-range wireless communication with the reader / writer, the position of the antenna can be clearly recognized.

  In the first embodiment, the slide mechanism SL is adopted. However, as the second embodiment, the rotation mechanism K shown in FIGS. 6A to 6D is adopted instead of the slide mechanism SL. May be. Further, as a third embodiment, instead of the slide mechanism SL, FIGS. 8A to 8C, FIGS. 9A to 9C, FIG. 10 and FIGS. 12A to 12 are used. The hinge mechanism H1 or the hinge mechanism H2 shown in (B) may be adopted. Furthermore, as a fourth embodiment, instead of the slide mechanism SL, the rotation mechanism K and the hinge mechanism H2 shown in FIGS. 15A to 15C may be simultaneously employed to assist. And as a 5th Example, you may process an assist control task with the straight type portable communication terminal of only the case C1 shown to FIG. 19 (A)-FIG. 19 (C).

Next, the second embodiment, the third embodiment, the fourth embodiment, and the fifth embodiment will be described.
Second Embodiment In the second embodiment, the rotation mechanism K has the configuration shown in FIG. 1 and is employed instead of the slide mechanism SL. In the second embodiment, the configuration of the mobile communication terminal 10 in FIG. 1 and the processing of the Felica mode control task in FIG. 4 used in the description of the first embodiment are the same. The figure and its description are omitted.

Referring to FIGS. 6A to 6D, the Felica circuit 24 is built in the case C2 so that the antenna 24a can ensure good reception sensitivity on the lower surface of the case C2. The key input device 26 is attached to the case C2 such that the operation key group is exposed on the upper surface of the case C2. The magnetic sensor 28 is built in the case C2. The magnet 30 is built in the case C1 so as to be closest to the magnetic sensor 28 in the state of FIGS. 6 (A) and 6 (B).
The main LCD monitor 32 is attached to the case C1 so that the monitor screen is exposed on the upper surface of the case C1.

  The rotation mechanism K is formed as a rotation mechanism on one side in the length direction of the outer surface of the case C2. The case C1 is coupled to the rotation mechanism K on the lower surface near one side in the length direction. The rotation mechanism K rotates the case C1 in the range of 0 to 360 degrees with the axis AX1 perpendicular to the upper surface of the case C2 as a reference in a state where the case C1 is stacked on the case C2. Therefore, the case C1 can take the posture shown in FIGS. 6A to 6D with respect to the case C2.

  The magnetic sensor 28 outputs a maximum value 255 in the state shown in FIGS. 6A and 6B, and outputs a minimum value 0 in the state shown in FIG. 6D. In the state shown in FIG. 6C, the magnetic sensor 28 does not output a minimum value but is regarded as an open state. Then, when the output value of the magnetic sensor 28 is rotated from FIG. 6 (A) and FIG. 6 (B) to FIG. 6 (D), the output value is decreased according to the rotation amount. That is, in the closed state shown in FIGS. 6A and 6B, the magnetic sensor 28 outputs a maximum value, and in the open state shown in FIG. 6D, the magnetic sensor 28 outputs a minimum value.

  In the second embodiment, the threshold value in the switching process between the open state and the closed state of the CPU 22 is the output value of the magnetic sensor 28 when the CPU 24 is rotated to the limit position where the position of the antenna 24a is within the display range of the main LCD monitor 32. And

  Referring to FIGS. 6A to 6D and FIGS. 3A to 3B, in the second embodiment, the schematic diagram 38 shows the key input device 26 attached to the upper surface of the case C2. The operation key group is schematically represented.

  In the closed state shown in FIGS. 6A and 6B, the rear side surface of the lower surface of the case C2 in which the antenna 24a is built is regarded as the upper surface of the case C1 to which the main LCD monitor 32 is attached. Therefore, the display range of the main LCD monitor 32 includes the position of the antenna 24a. Therefore, as in the first embodiment, the main LCD monitor 32 displays the assist mark 36 at the position of the antenna 24a with respect to the display range of the main LCD monitor 32.

That is, the antenna 24 a is present behind the assist mark 36 displayed on the main LCD monitor 32. Then, the user touches the surface where the reception sensitivity of the antenna 24a is satisfactorily secured, for example, the lower surface of the case C2, so that the position of the assist mark 36 displayed on the main LCD monitor 32 and the reader / writer overlap. What is necessary is just to make it close to a reader / writer.

  In the open state shown in FIGS. 6C and 6D, the back side surface of the lower surface of the case C2 in which the reception sensitivity of the antenna 24a is ensured is the upper surface of the case C2. Therefore, the display range of the main LCD monitor 32 does not include the position of the antenna 24a. Therefore, as in the first embodiment, the main LCD monitor 32 displays a schematic diagram 38 of the upper surface of the case C2, and displays the assist mark 36 at the position of the antenna 24a with respect to the upper surface of the case C2.

  That is, the antenna 24a is present on the back side of the upper surface of the case C2 corresponding to the schematic diagram 38 displayed on the main LCD monitor 32. The user has good reception sensitivity of the antenna 24a so that the position indicated by the assist mark 36 and the reader / writer overlap each other on the upper surface of the case C2 corresponding to the schematic diagram 38 displayed on the main LCD monitor 32. The secured surface, for example, the lower surface of the case C2 may be brought close to the reader / writer.

  Further, the CPU 22 detects a change in the position of the antenna 24a relative to the main LCD monitor 32 from the output value of the magnetic sensor 28 when the output value of the magnetic sensor 28 changes in the closed state, and the assist mark 36 is based on the detection result. Move. For example, when the value of the magnetic sensor 28 continuously changes, the position of the antenna 24a with respect to the main LCD monitor 32 changes in the same manner, so that the assist mark 36 is displayed on the main LCD monitor 32 as an animation.

  That is, when the CPU 22 rotates from the state shown in FIGS. 6A and 6B to the state shown in FIGS. 6C and 6D, the position of the assist mark 36 is set in the closed state. Move in stages. Then, the user can adjust the reception sensitivity of the antenna 24a so that the position of the assist mark 36 displayed on the main LCD monitor 32 overlaps the reader / writer corresponding to the position of the assist mark 36 moved in stages. A well secured surface such as the lower surface of the case C2 may be brought close to the reader / writer.

Similar to the first embodiment, the CPU 22 executes a plurality of tasks including the Felica mode control task shown in FIG. 4 and the assist control task shown in FIG. 5 in parallel. As in the first embodiment, control programs corresponding to these tasks are stored in the flash memory 20, and the assist mark 36 and the image data shown in the schematic diagram 38 shown in FIGS. Is stored in the flash memory 20 and read from the flash memory 20 in accordance with the assist control task process.

  Since the processing of the Felica mode control task of the second embodiment is the same as that of the first embodiment, a description thereof will be omitted. An assist control task according to the second embodiment will be described. Referring to FIG. 5, in step S13, it is determined whether or not the output value of magnetic sensor 28 is equal to or greater than a threshold value. If “NO” here, the output value of the magnetic sensor 28 is equal to or less than the threshold value, so that the open state shown in FIGS. 6C and 6D is obtained. In step S15, the main LCD monitor 32 displays a schematic diagram 38 of the upper surface of the case C2, and displays the assist mark 36 at the position of the antenna 24a with respect to the upper surface of the case C2. Subsequently, in step S17, it is determined whether or not the output value of the magnetic sensor 28 has changed. If “YES” here, the process returns to the step S13 in order to determine again whether or not the output of the magnetic sensor 28 is equal to or greater than the threshold value. If “NO” here, the process returns to the step S15 to display the schematic diagram 38 on the upper surface of the case C2 on the main LCD monitor 32 and continue to display the assist mark 36 at the position of the antenna 24a with respect to the upper surface of the case C2.

If YES in step S13, the output value of the magnetic sensor 28 is equal to or greater than the threshold value, and the closed state shown in FIGS. 6 (A) and 6 (B) is obtained. In step S 19, the position of the Felica circuit 24 relative to the main LCD monitor 32 is specified from the output value of the magnetic sensor 28. Subsequently, in step S21, the assist mark 36 is displayed on the main LCD monitor 32 at the position of the Felica circuit 24 specified in step S19.

  Subsequently, in step S23, it is determined whether or not the output value of the magnetic sensor 28 has changed. If “YES” here, the process returns to the step S13 in order to determine again whether or not the output of the magnetic sensor 28 is equal to or greater than the threshold value. If “NO” here, the process returns to the step S19 to repeat the processes of the steps S19 to S21, so that the assist mark 36 is continuously displayed at the position of the Felica circuit 24 specified in the step S19.

Further, when the case C1 rotates with respect to the case C2 in the closed state, the processes of step S13 and steps S19 to S23 are repeated. Therefore, the position of the antenna 24a with respect to the main LCD monitor 32 changes in the same manner, so that the assist mark 36 is displayed on the main LCD monitor 32 as an animation.
<Third Embodiment> In the third embodiment, the hinge mechanism H1 or the hinge mechanism H2 is employed in place of the slide mechanism SL in the configuration shown in FIG. Further, in the third embodiment, the processing of the Felica mode control task of FIG. 4 used in the description of the first embodiment is the same, so the description of FIG. 4 is omitted in the description of the third embodiment.

  Referring to FIG. 7, the mobile communication terminal 10 of the third embodiment further includes a sub LCD monitor 34 with respect to the mobile communication terminal 10 of the first embodiment.

The key input device 26 is attached to the case C2 such that the operation key group is exposed on the inner surface of the case C2. The magnetic sensor 28 is built in the case C2. The magnet 30 is built in the case C1 so as to be in a state closest to the magnetic sensor 28 in the state of FIGS. 8 (A) to 8 (C) and FIGS. 9 (A) to 9 (C). Is done. The main LCD monitor 32 is attached to the case C1 so that the monitor screen is exposed on the inner surface of the case C2. The sub LCD monitor 34 is attached to the case C1 such that the monitor screen is exposed on the outer side opposite to the inner side where the main LCD monitor 32 of the case C1 is attached. 8A and 9A, the sub LCD monitor 34 is not attached to the case C1.

  The hinge mechanism H1 is formed as a hinge mechanism on one side in the length direction of the inner side surface of the case C2. The case C1 is coupled to the hinge mechanism H1 on the side surface at one end in the length direction. Further, the hinge mechanism H1 moves the case C1 with reference to an axis AX2 parallel to the short side of the inner side surface of the case C2 in a state where the case C1 is stacked on the case C2. That is, the case C1 and the case C2 are opened and closed by rotation with the axis AX2 as a reference. Therefore, the case C1 can take the posture shown in FIGS. 8A to 8C, FIGS. 9A to 9C, and FIG. 10 with respect to the case C2.

  The magnetic sensor 28 outputs 255 which is the maximum value in the state shown in FIGS. 8A to 8C and 9A to 9C, and the minimum value in the state shown in FIG. A certain 0 is output. That is, in the closed state shown in FIGS. 8A to 8C and FIGS. 9A to 9C, the magnetic sensor 28 outputs a maximum value, and in the open state shown in FIG. The sensor 28 outputs a minimum value.

The switching process between the open state and the closed state of the CPU 22 is determined based on whether or not the output of the magnetic sensor 28 is the maximum value, not the threshold value employed in the first and second embodiments.

  The sub LCD monitor 34 can display an assist mark 36, a schematic diagram 38, and a character string.

  Referring to FIGS. 8A to 8C, FIGS. 9A to 9C, FIG. 10, and FIGS. 3A to 3B, the third embodiment is a schematic diagram. Reference numeral 38 schematically represents an operation key group of the key input device 26 attached to the inner surface of the case C2. 8A and 9A, the sub LCD monitor 34 is not attached to the case C1.

  In the closed state shown in FIGS. 8A to 8C, the rear side surface of the outer side surface of the case C1 in which the reception sensitivity of the antenna 24a is satisfactorily secured is the inner side of the case C1 to which the main LCD monitor 32 is attached. It becomes the side. Therefore, the display range of the main LCD monitor 32 includes the position of the antenna 24a. However, the main LCD monitor 32 cannot be displayed in the closed state. Therefore, the sub LCD monitor 34 is attached to the outer surface of the case 1. The attachment position of the sub LCD monitor 34 is shown in FIG. The sub LCD monitor 34 displays a character string that prompts the main LCD monitor 32 to be confirmed. Here, a display example of a character string prompting the main LCD monitor 32 to confirm is shown in FIG. That is, the user may check the main LCD monitor 32 in the open state shown in FIG. 10 according to the character string displayed on the sub LCD monitor 34.

  In the closed state shown in FIGS. 9A to 9C, the rear side surface of the outer surface of the case C2 in which the reception sensitivity of the antenna 24a is satisfactorily secured is outside the case C1 to which the sub LCD monitor 34 is attached. Consider side. Therefore, the display range of the sub LCD monitor 34 includes the position of the antenna 24a. Accordingly, the sub LCD monitor 34 is attached to the outer surface of the case 1 in the same manner as in FIG. The attachment position of the sub LCD monitor 34 is shown in FIG. The sub LCD monitor 34 displays the assist mark 36 at the position of the antenna 24 a with respect to the display range of the sub LCD monitor 34.

  That is, the antenna 24 a is present behind the assist mark 36 displayed on the sub LCD monitor 34. Then, the user can ensure that the reception sensitivity of the antenna 24a is ensured so that the position of the assist mark 36 displayed on the sub LCD monitor 34 and the reader / writer overlap, for example, the outer surface of the case C2. May be brought close to the reader / writer.

  In the open state shown in FIG. 10, the display content of the main LCD monitor 32 differs depending on the surface on which the reception sensitivity of the antenna 24a is satisfactorily ensured.

  When the surface on which the reception sensitivity of the antenna 24a is satisfactorily secured is the outer surface of the case C1, the rear side surface of the case C1 on which the reception sensitivity of the antenna 24a is satisfactorily secured is the main LCD monitor 32. Is the inner surface of the case C1 to which is attached. Therefore, the display range of the main LCD monitor 32 includes the position of the antenna 24a. Therefore, as in the first embodiment, the main LCD monitor 32 displays the assist mark 36 at the position of the antenna 24a with respect to the display range of the main LCD monitor 32.

  That is, the antenna 24 a is present behind the assist mark 36 displayed on the main LCD monitor 32.

May be brought close to the reader / writer.

  When the surface on which the reception sensitivity of the antenna 24a is satisfactorily secured is the outer surface of the case C2, the rear side surface of the case C2 on which the reception sensitivity of the antenna 24a is favorably secured is the inner side of the case C2. It becomes the side. Therefore, the display range of the main LCD monitor 32 does not include the position of the antenna 24a. Therefore, the main LCD monitor 32 displays a schematic diagram 38 of the inner surface of the case C2, and further displays the assist mark 36 at the position of the antenna 24a with respect to the inner surface of the case C2.

  Furthermore, when the sub LCD monitor 34 is attached to the outer surface of the case C1 in the open state shown in FIG. 10, the sub LCD monitor 34 displays a character string that prompts the user to check the main LCD monitor 32.

The case C1 is rotated with reference to the axis AX3 parallel to the side surface. That is, the direction of the surface of the case C1 is reversed by rotation with the axis AX3 as a reference. Therefore, the case C1 can further take the state shown in FIGS. 12A and 12B with respect to the case C2.

  When the hinge mechanism H2 is employed, the magnetic sensor 28 has a maximum value in the states shown in FIGS. 8 (A) to 8 (C), FIGS. 9 (A) to 9 (C), and FIG. 12 (B).

The back side surface of the outer side surface of C2 is the inner side surface of case C2. Therefore, the position of the antenna 24 a is not included in the display range of the sub LCD monitor 34. Therefore, the sub LCD monitor 34 displays a schematic diagram 38 of the inner surface of the case C2, and further displays the assist mark 36 at the position of the antenna 24a with respect to the inner surface of the case C2. Further, the main LCD monitor 32 displays a character string that prompts the sub LCD monitor 34 to confirm.

Therefore, the display range of the main LCD monitor 32 includes the position of the antenna 24a. Therefore, the main LCD monitor 32 displays the assist mark 36 at the position of the antenna 24a with respect to the display range of the main LCD monitor 32.

The CPU 22 executes a plurality of tasks including the Felica mode control task shown in FIG. 4 and the assist control task shown in FIGS. 13 and 14 in parallel. The control programs corresponding to these tasks are stored in the flash memory 20, and the assist mark 36 and the image data of the schematic diagram 38 shown in FIGS. 3A to 3C and the character string shown in FIG.

In the state shown in FIG. 12B, the assist mark 36 is displayed on the main LCD monitor 32 at the position of the antenna 24 a with respect to the main LCD monitor 32.

  If “NO” in the step S45, the process proceeds to a step S51 because of the open state shown in FIG. 10 and FIG. Then, in the state shown in FIG. 10, the main LCD monitor 32 displays a schematic diagram 38 of the inner surface of the case C2, and further displays the assist mark 36 at the position of the antenna 24a with respect to the inner surface of the case C2.

In the state shown in FIG. 12A, a character string that prompts the user to confirm the sub LCD monitor 34 is displayed on the main LCD monitor 32.

  Further, when the process of step S49 or step S53 is completed, the process returns to step S45 in order to determine again whether or not the output of the magnetic sensor 28 is the maximum value.

  If NO in step S43, the process proceeds to step S55 to determine whether or not the output value of the magnetic sensor 28 is the maximum value. If “YES” here, the process proceeds to a step S57 because of the closed state shown in FIG. Then, it is determined that the assist mark 36 cannot be displayed on the main LCD monitor 32 in the closed state.
