The display unit 2 displays a still image or a moving image based on a control signal from the control unit 5.
When the screen on the display unit 2 is pressed, the operation unit 3 generates a press signal and outputs it to the control unit 5.
The antenna 41 and the antenna 42 transmit radio waves to the RF tag, and receive the reflected waves when the transmitted radio waves are reflected from the RF tag. In addition, the antenna 41 and the antenna 42 acquire the received reflected wave as “radio wave intensity”, and output the acquired radio wave intensity to the control unit 5.
Here, the antenna 41 and the antenna 42 are used as antennas for RFID, but the present invention is not limited thereto. For example, the antennas 41 and 42 may be used as antennas for LAN (Local Area Network) or WAN (Wide Area Network).

  In the description of the present invention, the “RF tag” refers to a card shape in which the structure of an electronic element such as an IC chip and an antenna is embedded, as being capable of exchanging information by performing short-range wireless communication using RFID technology. It is described as a generic term for non-contact IC cards and RFID tags. In each description, the shape of the RF tag is described by taking a card type as an example. However, the shape is not limited to this, and various shapes such as a coin type, a stick type, a label type, and a wristwatch or a mobile phone are embedded. It is good also as a thing. The same applies to the second and subsequent embodiments.

The control unit 5 includes a CPU, a RAM, a ROM, and the like. The CPU expands various programs stored in the ROM and the storage unit 6 in the RAM, and cooperates with the expanded various programs in the portable terminal 1. Control the overall operation.
For example, the control unit 5 executes an application stored in the storage unit 6 to perform short-range wireless communication with the RF tag, and performs display processing (see FIG. 3) at that time.

The storage unit 6 is a volatile memory or a non-volatile memory such as a ROM, RAM, HDD, or flash memory. The storage unit 6 stores various programs executed by the control unit 5, and stores various information obtained by executing the various programs.
For example, the storage unit 6 stores RFID application software, an RF tag authentication table, an identification code, a management tool, and the like, and stores various information acquired by short-range wireless communication.

  The power supply unit 7 is a secondary battery called a battery, and supplies power to each unit (2 to 6) of the mobile terminal 1. In FIG. 2, the power supply line is not shown. The power supply unit 7 supplies power to each unit so as to save power based on the control of the control unit 5.

With reference to FIG. 3, the display process of the portable terminal 1 at the time of short-distance wireless communication is demonstrated.
With this process, when the RF tag is held over the portable terminal 1, various guidance can be displayed in the display area not covered with the RF tag, so that the convenience of the user can be improved.

As a premise, it is assumed that an application for performing short-range wireless communication with the RF tag is started in the mobile terminal 1 and an initial screen is displayed on the display unit 2. As the initial screen, for example, a guidance “Please hold the card” is displayed in the center of the display area of the display unit 2.
In the following description, it is assumed that this process is performed when reading information written in the RF tag, but this process is also performed in the same manner when writing.

The control unit 5 starts scanning with the antenna 41 and the antenna 42 (step S1).
The control unit 5 determines whether or not the identification code of the RF tag is detected from the antenna 41 or the antenna 42 (step S2).

When the identification code is not detected (step S2; N), the control unit 5 scans until it is detected.
When the identification code is detected (step S2; Y), the control unit 5 acquires the radio wave intensity from the antenna 41 and the antenna 42 (step S3).

  The control unit 5 compares the radio wave intensity from the antenna 41 (hereinafter expressed as “41e”) with the radio wave intensity from the antenna 42 (hereinafter expressed as “42e”) (step S4).

When 41e <42e (step S4; 41e <42e), that is, when the radio wave intensity from the antenna 41 is smaller, the control unit 5 calculates the ratio of the display area not covered by the RF tag (step S5). .
For example, the control unit 5 calculates the ratio of the display area not covered with the RF tag by 41e / (41e + 42e).

  The controller 5 determines whether or not the calculated ratio is greater than 10% (step S6). Here, 10% is adopted as the determination reference value, but it is not necessarily limited thereto, and may be, for example, 20% or 30%.

When the calculated ratio is not larger than 10% (step S6; N), that is, when most of the display area of the display unit 2 is covered with the RF tag, the control unit 5 notifies an error (step S7). .
For example, the error notification is not limited to a buzzer sound from a speaker (not shown) but may be a voice notification “Please shift the card to the end”, or the backlight of the display unit 2 or an LED (not shown) blinks or lights. Etc. may be notified. At the same time, guidance for the user may be displayed on the display unit 2 that is covered with the RF tag and cannot be seen. Furthermore, notification by vibrating the casing or the like of the mobile terminal 1 by a vibration device (not shown) may be used.
After notifying the error, the control unit 5 proceeds to step S2.

When the calculated ratio is larger than 10% (step S6; Y), that is, when the display area of the display unit 2 is secured more than a certain area, the control unit 5 covers the installation area of the antenna 41 with the RF tag. It is detected as a display area that has not been displayed, and various types of guidance are displayed in the detected display area (step S8).
Examples of various guidance displayed include a reading instruction “Please hold again”, a reading result “Reading OK!”, A reading status “Reading now”, and the like.

The control unit 5 reads the information written in the RF tag with the antenna 42 having a high radio wave intensity (step S9).
At this time, the user can observe the guidance such as the reading status displayed in the display area of the display unit 2 while holding the RF tag, so that the convenience can be improved.

The control unit 5 determines whether the reading has been completed (step S10).
When the reading cannot be completed (step S10; N), the control unit 5 proceeds to step S3.
When the reading is completed (step S10; Y), the control unit 5 stops the power supply to the antenna 41 and the antenna 42, ends the scanning (step S11), and ends the short-range wireless communication by the mobile terminal 1. .

Returning to step S4, the control unit 5 compares the radio field intensity and if 41e ≧ 42e (step S4; 41e ≧ 42e), that is, the radio field intensity from the antenna 42 is smaller, or the antenna 41 and the antenna 42 If the radio field intensity is the same, the ratio of the display area not covered with the RF tag is calculated (step S12).
For example, the control unit 5 calculates the ratio of the display area not covered with the RF tag by 42e / (41e + 42e).

  The control unit 5 determines whether or not the calculated display area ratio is greater than 10% (step S13). Here, 10% is adopted as a criterion for determination, however, it is not necessarily limited to this. For example, 20% or 30% may be used.

When the ratio of the display area is not larger than 10% (step S13; N), the control unit 5 notifies an error by light or sound (step S14), and proceeds to step S2.
The content of the error notification by light or sound is the same as that of the error notification in step S7, and the description thereof is omitted here.

When the ratio of the display area is larger than 10% (step S13; Y), the control unit 5 displays various guidance in the installation area of the antenna 42 (step S15).
Since the content of the displayed guidance is the same as the guidance displayed in step S8, description thereof is omitted here.

The control unit 5 reads information written in the RF tag by the antenna 41 (step S16).
Thereafter, the control unit 5 proceeds to step S10 or S11 described above, and ends the short-range wireless communication by the portable terminal 1.

In the display process during the short-range wireless communication, the control unit 5 may simplify the process by omitting steps S5 to S7 and steps S12 to S14. Specifically, the control unit 5 compares the radio field intensity (step S4), and displays the guidance such as the reading status in the installation area of the antenna (41 or 42) having the lower radio field intensity (step S8 or Step S15) may be used.
In this case, since the ratio of the display area not covered with the RF tag is not calculated, the processing speed can be improved.

FIG. 4 shows a state before the RF tag is held over the portable terminal 1.
FIG. 5 shows a state after the RF tag is held over the portable terminal 1.
As shown in FIG. 4 and FIG. 5, when the RF tag is held in accordance with a reading instruction “Please hold the card.”, According to the present embodiment, the display area that is not covered by the RF tag is Reading status guidance such as “Reading” can be displayed. Since the guidance can be observed regardless of the position where the RF tag is held, the convenience of the user can be improved.

  As described above, according to the first embodiment, when the RF tag is held over the portable terminal 1 including the display unit 2, the display area not covered with the RF tag can be detected and detected. Guidance such as reading instructions can be displayed in the display area. Since the user can observe the guidance while holding the RF tag, convenience can be achieved.

  Further, among the radio field intensities acquired from the antenna 41 and the antenna 42, the installation area of the antenna having the smaller radio field intensity can be detected as a display area not covered with the RF tag, and is covered with the RF tag. Guidance can be displayed in no display area.

  Moreover, the information written in the RF tag can be read by the antenna having the higher radio wave intensity among the radio wave intensity acquired from the antenna 41 and the antenna 42.

  In addition, the radio wave intensity acquired from the antenna 41 and the antenna 42 is added, and the ratio of the radio wave intensity acquired from the antenna 41 (or the radio wave intensity acquired from the antenna 42) in the added radio wave intensity is determined in advance. When the value is larger than the specified value, the guidance is displayed, and when the value is smaller, the error can be notified by sound, light, vibration, character display, or the like.

  In addition, when the display area of the display unit 2 is divided into two when the antenna 41 and the antenna 42 are divided, the antenna 41 and the antenna 42 are installed so as to surround the divided area, so that the portable terminal has a sufficient display area. Can be miniaturized.

  Guidance displayed so as to be observable while holding the RF tag includes a reading instruction, a reading state, a reading result, and the like, and the user can observe them, so that convenience can be achieved.

Each is installed. Note that when a loop antenna made of a transparent conductive material is used, it may be installed on the surface of the display unit 2.

In FIG. 7, the external view of the portable terminal 12 is shown.
In addition, about the structure similar to the portable terminal 11, the same code | symbol is attached | subjected and description is abbreviate | omitted.
The mobile terminal 12 is different from the mobile terminal 11 in the antenna installation position, and the other configurations are the same. The mobile terminal 12 is configured to include four antennas 41 to 44 outside the display area of the display unit 2 and in the vicinity of the display area, and the four antennas 41 to 44 are respectively installed along the four sides of the display unit 2. Is done.

FIG. 8 shows a functional block diagram of the mobile terminal 11.
The portable terminal 11 includes a display unit 2, an operation unit 3, antennas 41 to 44, a control unit 5, a storage unit 6, a power supply unit 7, and the like.

The portable terminal 11 is different from the portable terminal 1 in that it includes four antennas 41 to 44, and the other functional configurations are the same, and thus the description thereof is omitted here.
Moreover, since the portable terminal 12 is the same structure as the portable terminal 11, description here is abbreviate | omitted.

With reference to FIG. 9, the display process of the portable terminal 11 at the time of short-distance wireless communication is demonstrated.
With this process, when the RF tag is held over the mobile terminal 11, the display area not covered by the RF tag can be accurately detected, and various guidance can be displayed in the display area not covered by the RF tag. Therefore, user convenience can be improved.

  As a premise, it is assumed that an application for performing short-range wireless communication with the RF tag is started in the mobile terminal 11 and an initial screen is displayed on the display unit 2. As the initial screen, for example, a guidance “Please hold the card” is displayed in the center of the display area of the display unit 2.

The control unit 5 starts scanning with the antennas 41 to 44 (step S21).
The control unit 5 determines whether or not the RF tag identification code is detected by any of the antennas 41 to 44 (step S22).

When the identification code is not detected (step S22; N), the control unit 5 scans until it is detected.
When the identification code is detected (step S22; Y), the control unit 5 acquires the radio wave intensity from the antennas 41 to 44 (step S23).

  The control unit 5 refers to a table stored in advance in the storage unit 6 and detects a display area that is not covered by the RF tag based on the acquired radio wave intensity and the table (step S24).

FIG. 10 shows the table T1.
In the table T1, the radio field intensity for each of the antennas 41 to 44 is associated with the display area predicted to be covered with the RF tag, and the display area predicted not to be covered with the RF tag is further displayed. It is associated.

  The radio wave intensity for each of the antennas 41 to 44 is obtained by distributing the radio wave intensity from 1 to 4 for each of the antennas 41 to 44. Here, the radio wave intensity is described as 1 = minimum, 2 = small, 3 = medium, and 4 = maximum. To do. It can be said that the antenna having a higher radio wave intensity receives a larger number of reflected waves from the RF tag, and thus is closer to the RF tag. The shaded portion has the highest radio wave intensity among the radio wave strengths 1 to 4 assigned to the antennas 41 to 44, and the antenna corresponding to the shaded portion serves as an antenna for reading information written on the RF tag. Adopted. In the case where there are a plurality of antennas having the highest radio field intensity, this table T1 is indicated by shading for the sake of convenience in adopting the antenna with the smaller antenna number for capturing information. It is an example and the present invention is not limited to this.

  The display area predicted to be covered with the RF tag is an area predicted based on the allocation state of the radio wave intensity for each of the antennas 41 to 44 and the installation positions of the antennas 41 to 44, and the RF tag is held over the display area. The position is predicted. For example, when the assignment state of the radio wave intensity is 4-4-1-1 in the order of the antennas 41 to 44 (table T1: first row), the radio wave intensity of the antennas 41 and 42 is the maximum. Are placed on the upper left and upper right in the display area, the RF tag is expected to be held over the display area where the antennas 41 and 42 are placed.

  The display area that is predicted not to be covered with the RF tag is a display area other than the display area that is predicted to be covered with the RF tag, and is an area that is not covered with the RF tag. When the radio wave intensity allocation state is, for example, 4-4-1-1 in the order of the antennas 41 to 44 (table T1: first row), the RF tag is held over the display area where the antennas 41 and 42 are installed. Therefore, the display area not covered by the RF tag is predicted to be the lower side.

  After acquiring the radio field intensity from the antennas 41 to 44, the control unit 5 determines whether the acquired radio field intensity is the radio field intensity 1 to 4, and based on the determination result and the table T1, covers it with the RF tag. An undisplayed display area is detected (step S24).

The control unit 5 displays various types of guidance in the detected display area (step S25).
Various guidances include, for example, a reading instruction “Please hold again”, a reading result “Reading OK!”, A reading status “Reading now”, and the like.

The control unit 5 reads the information written in the RF tag with an antenna having a high radio field intensity (step S26).
For example, the control unit 5 reads the information written in the RF tag by the antenna corresponding to the shaded portion in the table T1.

  At this time, the user can observe the guidance such as the reading status displayed in the display area of the display unit 2 while holding the RF tag, so that the convenience can be improved.

The controller 5 determines whether or not the reading has been completed (step S27).
When the reading cannot be completed (step S27; N), the control unit 5 proceeds to step S23.
When the reading is completed (step S27; Y), the control unit 5 stops the power supply to the antennas 41 to 44 and ends the scanning (step S28), and ends the short-range wireless communication by the mobile terminal 11.

  In addition, about the display process of the portable terminal 12, since the content of table T1 in said process differs, and others are the same, description here is abbreviate | omitted.

  As described above, according to the second embodiment, when the RF tag is held over the mobile terminal 11 or the mobile terminal 12 including the display unit 2, the display area not covered with the RF tag is accurately detected. And a guidance such as a reading instruction can be displayed in the detected display area. Since the user can observe the guidance while holding the RF tag, convenience can be achieved.
