[Constitution]
FIG. 1 is an explanatory view showing an embodiment of a portable terminal according to the present invention.
A portable terminal 100 as a paired portable terminal shown in FIG. 1 has a rectangular casing 11 mainly having a size that can be carried by a user (for example, B5 size to A4 size), and one main casing 11. Display unit 12 arranged almost on the whole surface except for the outer peripheral part of the surface (surface shown in the figure), touch panel 13 arranged on display unit 12, both left and right sides as the outer peripheral part in housing 11, both upper and lower sides Or detecting means (14a to 14d, 15a to 15d) for detecting the positions of other portable terminals that are arranged on the respective sides of the top, bottom, left and right.

Of the detection means (14a to 14d, 15a to 15d), 14a to 14d are magnets, and 15a to 15d are MR (Magnetic Resistance) sensors.
The magnet 14a is arranged on the lower side of the left side of the casing 11, the MR sensor 15a is arranged on the upper side of the left side of the casing 11, the magnet 14b is arranged on the upper side of the right side of the casing 11, and the MR sensor 15b is Arranged in a row on the lower side of the right side of the housing 11.

  The magnet 14c is arranged on the left side of the upper side of the casing 11, the MR sensor 15c is arranged on the right side of the upper side of the casing 11, the magnet 14d is arranged on the right side of the lower side of the casing 11, and the MR sensor 15d Arranged in a row on the left side of the lower side of the housing 11.

  The MR sensors 15a to 15d have a function of detecting when a magnet approaches within a predetermined distance (for example, 10 mm to 15 mm), and in this embodiment, the mobile terminals are arranged adjacent to each other (in a state of being in close contact with each other). It is set so that it can be detected.

  For this reason, when another mobile terminal is arranged adjacent to any one of the upper, lower, left, and right positions of one mobile terminal, the MR sensor that opposes the magnets 14a to 14d built in both adjacent sides of the two mobile terminals. By detecting 15a to 15d, it is possible to detect whether one mobile terminal is adjacent to the top, bottom, left, or right side of the other mobile terminal.

  In other words, the detection means (14a to 14d, 15a to 15d) is configured so that when any other mobile terminal is adjacently disposed at any of the top, bottom, left, and right positions of one mobile terminal, any of the magnets 14a to 14d The MR sensors 15a to 15d face each other at a position closest to the MR sensors 15a to 15d, so that one MR sensor is arranged so that it can detect accurately without detecting a magnet of the same distance.

  For example, when another mobile terminal is arranged adjacent to the right side of one mobile terminal, the MR sensor 14b of one mobile terminal detects the magnet 15a of the other mobile terminal, so that one mobile terminal is moved to the right side. It is determined that another mobile terminal is arranged adjacent to each other, and a signal for displaying the page on the right side of the one mobile terminal is transmitted to the display unit of the other mobile terminal.

Further, when an IC tag and an IC tag reader are used instead of the detection means (14a to 14d, 15a to 15d), information indicating the portable terminal is stored in the IC tag of each of the main terminal and the sub terminal. Since the IC tag reader of the partner mobile terminal is on both the left and right sides, it can be seen that the other mobile terminal is approaching either side.
That is, if the left and right IC tag readers detect the approach of another mobile terminal, it can be determined that the other mobile terminal approaches, for example, the left side. Since the mobile terminals can be understood from each other, the mobile terminal approaches the IC tag reader on the right side when viewed from other mobile terminals, so that it can be determined that the mobile terminal is approaching on the right side.
Since the information indicating the portable terminal is stored in the IC tag, the left terminal sends the information of the portable terminal approaching the right side to the right terminal by wireless communication, and the right terminal of the portable terminal approaching the left side If the information is sent to the left terminal and it is finally checked whether or not matching is performed, the positional relationship is determined. In the present embodiment, the case where the mobile terminals are arranged close to the left and right has been described. However, the present invention is not limited to this, and may be a case where the mobile terminals are arranged close to each other in the vertical direction.

  The display unit 12 is a device for displaying images and icons such as books and maps, and examples thereof include a liquid crystal display element and an electronic paper display element. The icons indicate “use main terminal”, “select application software”, “execute”, “end”, and the like. Among these, when the icon is touched by pressing the “set as the main terminal” icon, one mobile terminal (for example, the mobile terminal 100-1) whose icon is pressed functions as the main terminal, and the mobile terminal Data indicating that the mobile terminal is set as the sub-terminal is sent from 100 to the other mobile terminal, and is set as the sub-terminal.

  The touch panel 13 is a device for detecting gesture operations such as touching, dragging, and dropping icons by a user. Any of a touch panel analog resistance film method, a capacitance method, an infrared method, and an ultrasonic method may be used.

FIG. 2 is an example of a block diagram showing an electrical connection relationship of the mobile terminal 100 shown in FIG.

FIG. 3A is an explanatory diagram showing a state in which the two mobile terminals shown in FIG. 1 are arranged in the left-right direction (lateral direction), and FIG. 3B shows a state in which one mobile terminal is reversed upside down. FIG. 3C is an explanatory diagram for explaining a state when one mobile terminal is displaced in the vertical direction.
The mobile terminal 100 shown in FIG. 1 can display images of one page of books, magazines, maps, charts, etc. by itself. For example, an image of the Nth page (N is a natural number) can be displayed on the mobile terminal 100-1, and an image of the (N + 1) th page can be displayed in conjunction with the mobile terminal 100-2.

  In FIG. 3A, when the activated portable terminal 100-2 is arranged adjacent to the right side of the activated portable terminal 100-1, the magnet 14b-1 of the portable terminal 100-1 is connected to the portable terminal 100-2. The distance that can be detected by the MR sensor 15a-2 and the magnet 14a-2 of the mobile terminal 100-2 become a distance that can be detected by the MR sensor 15b-1 of the mobile terminal 100-1. As a result, the CPU 17 of the mobile terminal 100-1 determines that the mobile terminal 100-2 is adjacently disposed on the right side of the mobile terminal 100-1, and the CPU of the mobile terminal 100-2 determines that the mobile terminal 100-2 has the mobile terminal 100-2. It is determined that the mobile terminal 100-1 is disposed adjacent to the left side of the screen.

  Here, the user needs to set one of the mobile terminals 100-1 and 100-2 as the main terminal. For example, when the mobile terminal 100-1 is set as the main terminal, the mobile terminal 100-1 The mobile terminal 100-1 is set as the main terminal by touching an icon “notify as main terminal” or performing a gesture operation from among icons not shown.

When the mobile terminal 100-1 is set as the main terminal, the CPU 17 of the mobile terminal 100-1 sets the mobile terminal 100-1 as the main terminal from the wireless communication unit 22-1 to the wireless communication unit 22-2. Instruction data indicating that 100-2 is set as the sub-terminal is sent. The portable terminal 100-2 sends confirmation data indicating that the mobile terminal 100-2 has been set as the sub-terminal from the wireless communication unit 22-2 to the wireless communication unit 22-1.
Thereby, the portable terminal system which makes the portable terminal 100-1 a main terminal and uses the portable terminal 100-2 as a subterminal is comprised.

  That is, by touching or gesturing an icon (not shown) on the touch panel 13-1 of the mobile terminal 100-1 as the main terminal, the display unit 12- of the mobile terminal 100-1 is connected to the mobile terminal 100-2 as the sub terminal. The instruction data for displaying the next page of the page displayed in 1 is sent, and the image of the next page is displayed on the display unit 12-2 of the portable terminal 100-2.

  As shown in FIG. 3B, even if one of the pair of portable terminals is reversed upside down, the MR sensor and the magnet are in a positional relationship so as to operate effectively. Further, as shown in FIG. 3 (c), even if one of the paired mobile terminals is shifted in the vertical direction and approaches, the MR sensor and the magnet do not approach, so no problem occurs.

In each of the terminals 1 and 2, the main subject of operation is a built-in CPU.
In the flowchart on the terminal 1 side, when the terminal 1 is activated (step S1), an application (application) is activated and the MR sensor starts detecting a magnet (step S2).
When the MR sensor does not detect the magnet (step S3 / No), the terminal 1 performs the normal operation of the application (step S4). When the MR sensor detects the magnet (step S3 / Yes), the display unit displays “Start cooperation”. Is displayed? (Step S5), and a standby state is entered (step S6).
As a wireless communication means, the terminal 1 searches for a terminal in a cooperative standby state by communication using, for example, WiFi (registered trademark) (step S7).
The terminal 1 waits until it finds a terminal in the cooperation standby state (step S8 / No), and if it finds a terminal in the cooperation standby state (step S8 / Yes), it selects whether it becomes the main terminal or the sub terminal. .

Here, when the terminal 1 is selected as the main terminal (step S9), the terminal 1 performs position alignment (step S10), starts sub-terminal screen data transmission to the terminal 2 as the sub-terminal (step S11), and the terminal 1 A screen display is performed (step S12).
The terminal 1 returns to step S11 when continuing the operation (step S13 / No), and ends when ending (step S13 / Yes).
The terminal 1 confirms the presence / absence of an application termination instruction from the user, and terminates if there is an termination instruction (step S13 / Yes). If there is no end instruction, the process returns to step S11 (step S13 / No).

On the other hand, in the flowchart on the terminal 2 side, when the terminal 2 is activated (step S21), the application is activated and the MR sensor starts detecting the magnet (step S22).
When the MR sensor does not detect the magnet (step S23 / No), the terminal 2 performs the normal operation of the application (step S24). When the MR sensor detects the magnet (step S23 / Yes), the terminal 2 displays “ "Do you want to start cooperation?" Is displayed (step S25), and a cooperation standby state is entered (step S26).

The terminal 2 searches for a terminal in a cooperation standby state through communication using WiFi (registered trademark) as a wireless communication unit via the network (step S27).
The terminal 2 waits until it finds a terminal in the cooperation standby state (step S28 / No), and if it finds a terminal in the cooperation standby state (step S28 / Yes), it selects whether to become the main terminal or the sub terminal. .
However, in the present embodiment, since the terminal 1 is selected as the main terminal, the terminal 2 is automatically set as the sub terminal (step S29).

The terminal 2 starts receiving the sub terminal screen data from the terminal 1 as the main terminal (step S30), and displays the received data on the sub terminal screen (step S31).
Similarly to the terminal 1, the terminal 2 confirms the presence / absence of an application termination instruction from the user, and terminates if there is an termination instruction (step S32 / Yes). When there is no end instruction, the process returns to step S30 (step S32 / No).

  Here, the end can be realized by touching an end icon (not shown) on the touch panels of both terminals 1 and 2 or by performing an end gesture on the touch panel.

Note that the steps S2 and S3 of the terminal 1 and the steps S22 and S23 of the terminal 2 mean steps for detecting a proximity device by the detecting means.
Steps S7 and S8 of the terminal 1 and steps S27 and S28 of the terminal 2 mean steps for determining the neighboring devices on the network.
Step S11 of terminal 1 and steps S30 and S31 of terminal 2 mean screen transmission steps.

  In the above, when the paired mobile terminals 200-1 and 200-2 are arranged adjacent to each other in the vertical and horizontal directions, by setting one as the main terminal, the pair of mobile terminals 200-1 and 200-2 can be used as magazines or books.

[Operation]
FIG. 12 is an example of a flowchart for explaining the operation in the case where four mobile terminals shown in FIG. 9 are arranged vertically and horizontally.
In the same figure, the flowchart of the terminal 1 as the portable terminal 200-1 and the flowchart of the terminals 2-4 as the portable terminals 200-2 to 200-4 are shown.

In each of the terminals 1, 2 to 4, the main subject of the operation is a built-in CPU, but the main subject that selects whether to be the main terminal or the secondary terminal is the user.
In the flowchart on the terminal 1 side, when the terminal 1 is activated (step S41), the application is activated and IC tag detection is started (step S42).
When the detection unit does not detect the IC tag (step S43 / No), the terminal 1 performs the normal operation of the application (step S44). When the detection unit detects the IC tag (step S43 / Yes), the mobile device that is the detection device The terminal UID is obtained (step S45).
The terminal 1 displays “Do you want to start cooperation?” On the display unit (step S46), and enters the cooperation standby state (step S47).
The terminal 1 searches for a terminal in a cooperative standby state by communication using WiFi (registered trademark) as a wireless communication means (step S48).
The terminal 1 waits until it finds a terminal in the cooperation standby state (step S49 / No), and if it finds a terminal in the cooperation standby state (step S49 / Yes), it collects neighboring neighboring device information and obtains terminal location relationship information. Create (step S50).
The terminal 1 is selected by the user as a main terminal or a sub terminal (step S51).

  Here, when the user selects the terminal 1 as the main terminal and the CPU collects the terminal positional relationship information of the terminals 2 to 4 and creates the entire map (step S52), the terminal 1 displays the instruction data of the image to be displayed, Alternatively, transmission of secondary terminal screen image data is started (step S53). As a result, the terminals 2 to 4 as the sub terminals display an image adjacent to the image displayed on the display unit of the terminal 1 (step S54).

In addition, when a terminal (device) is newly arranged in the terminals 1 to 4, the following operation is added.
That is, the terminal 1 searches for a terminal in a cooperation standby state by communication using WiFi (registered trademark) as a wireless communication unit (step S55).
If the terminal 1 does not find a terminal in the cooperation standby state (step S56 / No), the terminal 1 determines whether or not to end the application, and ends if the application is not continued (step S58 / Yes).
When the terminal 1 finds a terminal in the cooperation standby state (step S56 / Yes), the terminal 1 collects terminal positional relationship information, creates an entire map (step S57), and returns to step S53.
The terminal 1 starts transmitting the instruction data of the image to be displayed on the sub-terminal screen or the sub-terminal screen image data (step S58) and displays the screen (step S59).
If the terminal 1 continues the application (step S58 / No), the terminal 1 returns to step S53.

  The terminal 1 confirms the presence / absence of an application termination instruction from the user, and terminates when there is an termination instruction (step S58 / Yes). If not, the process returns to S53 (step S58 / No).

On the other hand, in the flowchart on the side of the terminals 2 to 4, when the terminals 2 to 4 are activated (step S61), the application is activated and IC tag detection is started (step S62).
When the detection unit does not detect the IC tag (step S63 / No), the terminals 2 to 4 perform the normal application operation (step S64). When the detection unit detects the IC tag (step S63 / Yes), the detection device A UID of a certain mobile terminal is obtained (step S65).
The terminals 2 to 4 display "Do you want to start cooperation?" On the display unit (step S66), and enter a cooperation standby state (step S67).
The terminals 2 to 4 search for a terminal in a cooperative standby state by communication using WiFi (registered trademark) as a wireless communication unit (step S68).
The terminals 2 to 4 stand by until they find a terminal in the cooperation standby state (step S69 / No), and when they find a terminal in the cooperation standby state (step S69 / Yes), collect neighboring neighboring device information and collect the terminal positional relationship Information is created (step S70).
The terminals 2 to 4 are selected by the user as the main terminal or the sub-terminal (step S71).

Here, since the terminal 1 is set as a main terminal by the user, the terminals 2 to 4 are automatically set as sub-terminals.
The terminals 2 to 4 transmit the terminal location relationship information to the terminal 1 (step S72), receive the sub terminal screen data (step S73), display the received data on the sub terminal screen (step S74), and The presence / absence of an application end instruction is confirmed, and if there is an end instruction, the process ends (step S75 / Yes). If not, the process returns to S73 (step S75 / No).

  Here, the termination instruction can be realized by touching a termination icon (not shown) on the touch panel of the terminal or by performing a termination gesture on the touch panel.

Steps S42 to S43 of the terminal 1 and steps S62 to S63 of the terminals 2 to 4 mean steps for detecting a proximity device by the detection means.
Steps S48 to S50 of the terminal 1 and steps S68 to S70 of the terminals 2 to 4 mean steps for determining a neighboring device on the network.
Steps S55 to S57 of the terminal 1 and step S75 of the terminals 2 to 4 mean steps for searching for device addition.

  In the above, when the group mobile terminals 200-1 to 20-4 are arranged adjacent to each other vertically and horizontally, one of them is set as the main terminal, so that the image displayed on the sub-terminal is linked to the image displayed on the main terminal. Can be displayed.
