The display 15 is configured by, for example, an LCD (Liquid Crystal Display), displays information associated with normal processing by the electronic device 9, and displays information representing a communication state during execution of close proximity wireless communication.

The close proximity wireless communication unit 16 performs close proximity wireless communication with other devices under the control of the CPU 10 (close proximity wireless communication control function). The proximity wireless communication by the proximity wireless communication unit 16 executes high-speed wireless communication specialized for P2P (peer-to-peer), for example.

  2A, 2 </ b> B, 2 </ b> C, and 2 </ b> D are diagrams illustrating an external configuration of the electronic device 9 in the present embodiment. 2A is a rear view of the electronic device 9, FIG. 9B is a top view of the electronic device 9, FIG. 9C is a front view of the electronic device 9, and FIG. 9D is an electronic device. Side views of the device 9 are shown respectively.

  In the configuration shown in FIGS. 2A to 2D, it is assumed that the antenna 16 a is disposed in the vicinity of the upper end on the back side in the housing of the electronic device 9. In this case, the locking member 32 is provided on the surface of the casing near the position where the antenna 16a is disposed. That is, in FIGS. 2A and 2B, the locking member 32 is provided at the upper end on the back side of the electronic device 9.

  Further, the communication target 30 is provided in accordance with the position where the antenna 16a is disposed. Since the locking member 32 is provided in the vicinity of the antenna 16a, the communication target 30 is disposed so as to include the position where the locking member 32 is provided. The communication target 30 is for indicating to the user that it is a place where close proximity wireless communication is performed (a place where the antenna 16a for transmitting and receiving wireless signals is present). The communication target 30 is represented by a rectangular shape, for example. The size of the communication target 30, that is, the length of one side of the rectangle is preferably shorter than the communicable distance (for example, 30 mm) for close proximity wireless communication, for example. By making the length of one side of the communication target 30 shorter than the communicable distance, the user can grasp the distance in which wireless communication is possible in a sensibly stable state based on the size of the communication target 30. To do.

  Further, as shown in FIG. 2C, a communication method mark 31 is provided on the surface of the electronic device 9 at a position opposite to the position where the communication target 30 is provided, that is, at the upper end on the surface side. The communication method mark 31 indicates that the electronic device 9 has a short-range wireless communication function. For example, a logo mark or a character indicating near-field wireless communication is added. In the example shown in FIG. 2C, the character string “ABC” is attached. The communication method mark 31 is represented by a rectangular shape, for example, in the same manner as the communication target 30. The size of the communication method mark 31, that is, the length of one side of the rectangle is preferably shorter than the communicable distance (for example, 30 mm) for close proximity wireless communication, for example. That is, in the same manner as the communication target 30, the user can grasp the distance at which wireless communication can be performed in a sensibly stable state based on the size of the communication target 30. The communication target 30 and the communication method mark 31 are preferably the same size and shape.

  Further, the communication method mark 31 is provided with a communication lamp 21. The communication lamp 21 is for indicating the wireless state by the proximity wireless communication, and expresses the communication state by, for example, lighting / flashing or lighting color. The communication lamp 21 is provided in the communication system mark 31, for example, on the position side where the antenna 16a is arranged. In FIG. 2C, a communication lamp 21 is provided on the upper end side. In FIG. 2C, only one communication lamp 21 is provided, but two or more communication lamps 21 may be provided to express the communication state.

  By disposing the communication method mark 31 on the surface of the electronic device 9, the user can locate the position where the antenna 16a is disposed, that is, the position of the locking member 32 provided on the back side to be locked with another device. It can be easily confirmed from the surface side. Further, the user can confirm whether the proximity wireless communication is normally performed by the communication lamp 21 and can determine that the locked state with the other device is correctly maintained.

  3A and 3B are views showing details of the locking member 32 shown in FIGS. 2A and 2B. The locking member 32 is configured by a combination of a concave portion 33 and a convex portion 34, for example. The concave portion 33 and the convex portion 34 are formed of, for example, an elliptical sphere or a part of a shape similar to an elliptical sphere (a shape obtained by crushing a hemisphere up and down). In addition, each of the concave portion 33 and the convex portion 34 is disposed so that the major axis of the elliptical sphere is parallel to the upper end of the housing of the electronic device 9. That is, by making the vertical width narrower than the horizontal width of the concave portion 33 and the convex portion 34, it can be easily disposed in a corner portion of the electronic device 9 (see FIGS. 10 and 11).

  As shown in FIGS. 3A and 3B, the concave portion 33 is recessed from the housing surface of the electronic device 9, and the convex portion 34 protrudes from the housing surface of the electronic device 9. Therefore, if the same locking member 32 (concave portion 33, convex portion 34) is provided in another device as a counterpart of the close proximity wireless communication, the electronic device 9 can be brought into contact with each other by bringing the locking member 32 into contact with each other. The convex part provided in the other device fits into the concave part 33 of the electronic device 9, and the convex part 34 of the electronic device 9 fits into the concave part provided in the other device. That is, since the locking member 32 of the electronic device 9 and the locking member provided in another device are engaged, the electronic device 9 and the other device are brought into light contact with each other. It is possible to suppress misalignment with other devices.

FIG. 4 is a view for explaining the relationship between the locking member 32 (concave portion 33, convex portion 34) and the arrangement position of the antenna 16a in the present embodiment.
As shown in FIG. 4, the concave portion 33 and the convex portion 34 are disposed in the vicinity of the position where the antenna 16a is disposed, for example, on the surface of the casing above the position where the antenna 16a is disposed. Therefore, the distance between the electronic device 9 and the antenna provided in the other device can be minimized by locking with the other device as the communication partner by the locking member 32.

  In addition, the antenna installation position can be devised using the convex part 34, and the distance between antennas can be shortened. For example, the antenna 16 a is disposed inside the convex portion 34. Since the convex part 34 protrudes from the housing | casing surface, it reaches inside from the housing | casing surface of another apparatus by fitting in the recessed part provided in the other apparatus of the communicating party. Therefore, the antennas arranged inside the convex portions of the electronic device 9 and other devices reach the inside of the counterpart housing. That is, it is possible to bring the antennas closer to each other than when the antenna is disposed below the locking member 32. Proximity wireless communication can be performed more stably by bringing the antenna closer.

  In addition, even when the housing of the electronic device 9 and another device is not in contact, the antenna 16a is disposed below the locking member 32 by disposing the antenna 16a inside the convex portion 34. The distance between the antennas will be shortened.

  In the example shown in FIG. 4, a case where the concave portion 33 and the convex portion 34 are not provided at the housing end portion is shown. Accordingly, the communication target 30 is provided so that the concave portion 33 and the convex portion 34 are disposed substantially at the center.

FIG. 5 is a diagram illustrating a state in which the locking members 32 provided in the two electronic devices 9 (portable devices 36 and 37) in the present embodiment are opposed to each other.
As shown in FIG. 5, in each of the devices 36 and 37 that perform close proximity wireless communication, the concave portions 33a and the convex portions 34a having the same arrangement and the same shape are disposed, and the concave portions 33b and the convex portions 34b are respectively disposed. The concave portion 33 a faces the convex portion 34 b of the portable device 37, and the convex portion 34 a of the portable device 36 faces the concave portion 33 b of the portable device 37. Therefore, by bringing the portable device 36 and the portable device 37 into contact with each other at the locking members (the concave portions 33a and 33b and the convex portions 34a and 34b), they can be locked to each other at the contact position and the displacement can be suppressed.

FIG. 6 is a diagram illustrating the magnetic force applied to the locking member 32 (concave portion 33, convex portion 34) in the present embodiment.
The electronic device 9 can apply a magnetic force of a predetermined magnetic pole to each of the concave portion 33 and the convex portion 34 by the fixing device 19. In the example shown in FIG. 6, an S-pole magnetic force is applied to the concave portion 33, and an N-pole magnetic force is applied to the convex portion 34. Similarly, in the locking member provided in another device, an S-pole magnetic force is applied to the concave portion 33 and an N-pole magnetic force is applied to the convex portion 34.

  Therefore, the electronic device 9 and the other devices can maintain the fixed state not only by the locking by the unevenness formed in the locking member 32 but also by the magnetic force.

  The electronic device 9 controls the fixing device 19 by the fixing device control unit 18 according to the state of the close proximity wireless communication via the antenna 16 a by the close proximity wireless communication unit 16, thereby applying a magnetic force to the concave portion 33 and the convex portion 34. Can be added.

  That is, when performing close proximity wireless communication with other devices, the CPU 10 controls close proximity wireless communication by the close proximity wireless communication unit 16 by the close proximity wireless communication control function. The CPU 10 drives the fixing device 19 through the fixing device control unit 18 by the fixing control function when the preparation for the close proximity wireless communication is completed. For example, by using an electromagnet in the fixing device 19, an S-pole magnetic force is applied to the concave portion 33 and an N-pole magnetic force is applied to the convex portion 34 as shown in FIG. 6.

  By generating the magnetic force in the locking member 32, the user can easily engage the locking member 32 of the electronic device 9 with the locking member of another device by using the magnetic force. The locked state by the locking member 32 can be more stably fixed.

  In addition, when the proximity wireless communication by the proximity wireless communication control function is completed, the CPU 10 stops the driving of the fixing device 19 by the fixed control function. That is, the magnetic force from the concave portion 33 and the convex portion 34 is erased.

  In this manner, by controlling the generation / extinction of the magnetic force in the locking member 32 according to the state of the proximity wireless communication, the proximity wireless communication can be performed for the user who is holding the electronic device 9 in his / her hand. Start / end can be recognized.

  In the above description, the fixing device 19 is described as applying magnetic forces having different polarities (N pole and S pole) to the concave portion 33 and the convex portion 34, respectively, but the concave portion 33 and the convex portion 34 are described. May be formed by a member having magnetic force, that is, a magnet. In this case, a magnetic force is always generated from the concave portion 33 and the convex portion 34. In this case, the generation / disappearance of the magnetic force in the locking member 32 makes it impossible for the user to recognize the start / end of close proximity wireless communication, but the magnetic force is applied by the fixing device 19 via the fixing device control unit 18. The structure to perform can be made unnecessary.

Next, a method for notifying the user of the state of close proximity wireless communication by control of the close proximity wireless communication control function will be described.
When the display 15 is provided in the electronic device 9, the CPU 10 displays the communication status of the close proximity wireless communication on the display 15 by the communication state display function according to the close proximity wireless communication state by the close proximity wireless communication control function. In this case, the communication status is displayed on the display 15 at a position close to the communication method mark 31 or the communication target 30.

FIGS. 7A and 7B are diagrams illustrating examples of communication status displays 40a and 40b on the display 15 in the present embodiment.
The communication status displays 40a and 40b are formed in a balloon shape as shown in FIG. 7A or shown in FIG. 7B in order to clarify the relationship with the communication method mark 31 and the communication target 30. Or shape like an arrow.

The communication status displays 40a and 40b display, for example, radio wave intensity and communication progress.
FIG. 8 shows an example of the communication status display 40a in the present embodiment. In the example shown in FIG. 8, the radio wave intensity display 40c is represented by a mark such as a circle. In addition, the progress of data communication by proximity wireless communication can be represented by the ratio of the data communication amount that has been completed to the total data communication amount, or can be displayed by the remaining data communication time (number of remaining seconds).

  By referring to the radio wave intensity display 40c, the user can adjust the position of the electronic device 9 with respect to other devices so that the proximity wireless communication can be executed in a more stable state. In addition, it is possible to know how long it will take for the communication to be completed if the communication remaining amount or the current communication speed is determined by the progress of communication.

  The communication status display may display a message for the user such as “Please touch”, “Communicating”, “Communication completed”, and the like.

  Further, the CPU 10 controls the lighting / flashing of the communication lamp 21 provided in the communication method mark 31 or the display color by the communication lamp control function according to the state of the close proximity wireless communication by the close proximity wireless communication control function. It is also possible to notify the user of the situation. For example, the CPU 10 can express the radio wave intensity by the blinking interval of the communication lamp 21 by the communication lamp control function. That is, the shorter the blinking interval is, the stronger the radio wave intensity is. When the radio wave intensity is such that stable close proximity wireless communication is possible, the communication lamp 21 is turned on. Further, the communication progress is represented by a display color. For example, the display color of the communication lamp 21 is sequentially changed in accordance with the change in communication progress. For example, the communication lamp 21 is red when the progress is 25% or less, orange when it is 50% or less, yellow when it is 75% or less, and green when it is 100% (communication completed). Lights up.

  The above-described lighting / flashing display of the communication lamp 21 is an example, and can be arbitrarily set.

  Further, the communication target 30 and the communication method mark 31 are disposed at relatively close positions on the surface of the casing of the electronic device 9. In addition, the communication lamp 21 provided in the communication method mark 31 is provided on the side where the communication target 30 is arranged.

9A and 9B show an arrangement example of the communication target 30 and the communication method mark 31 (communication lamp 21) in the present embodiment.
In the example shown in FIGS. 9A and 9B, an example is shown in which the communication target 30 and the communication method mark 31 are provided on the same casing surface. In the case of FIG. 9A, since the communication target 30 is disposed below the communication method mark 31, the communication lamp 21 is disposed below the communication method mark 31. In the case of FIG. 9B, the communication lamp 30 is disposed above the communication method mark 31 because the communication target 30 is disposed above the communication method mark 31.

  In the case of the portable electronic device 9, the communication target 30 is arranged on the back surface of the communication method mark 31 as shown in FIGS. Furthermore, in the electronic device 9 that the user holds and operates with the hand, it is preferable that the communication target 30 is disposed at a corner corresponding to the back of the upper end of the housing when the user holds the device. The communication target 30 provided at the corner is formed to bend along the casing. That is, the communication target 30 is formed so as to straddle the back and top surfaces of the housing. In this case, the antenna 16a is disposed in the vicinity of the inside of the casing at the corner where the communication target 30 is disposed.

FIG. 10 is a diagram illustrating a usage method when the communication target 30 is arranged at the corner of the back surface of the upper end of the housing of the electronic device 9 (the mobile devices 36 and 37).
As shown in FIG. 10, when the user uses the portable devices 36 and 37 while holding them, the communication targets 30 a and 30 b are arranged at the corners on the back of the upper end of the housing, respectively. The locking member 32 provided in 30b can be easily aligned. That is, it is possible to prevent the hands holding the portable devices 36 and 37 from contacting each other's devices. For this reason, it is possible to easily match the communication targets 30a and 30b with good operability.

FIG. 11 is a diagram illustrating a state in which the communication targets 30a and 30b of the mobile devices 36 and 37 are brought into contact with each other. As shown in FIG. 11, the communication targets 30 a and 30 b are arranged at the corners of the casing, so that the concave portions 33 and the convex portions 34 provided on the respective locking members 32 are locked with each other. By arranging the antenna 16a at the corner portion, as shown in FIG. 11, when the portable devices 36 and 37 are locked by the locking member, the mutual relationship is greater than when the antenna 16a is positioned at the flat portion of the housing. The distance between the antennas can be shortened.

Next, a specific example of another device that performs close proximity wireless communication with the electronic device 9 will be described.
FIGS. 12A, 12B, and 13 are diagrams illustrating an example of a fixed device 50 that is vertically installed, such as a television device. FIG. 12 is a front view of the fixed device 50, and FIG. 13 is a side view illustrating a state in the case where close proximity wireless communication is performed between the electronic device 9 and the fixed device 50.

  As shown in FIG. 12A, the fixed device 50 that performs close proximity wireless communication with the electronic device 9 is provided with a locking member that is locked with the locking member 32 provided in the electronic device 9. A target 53 is provided on the front side of the housing. The communication target 53 is provided with a locking member provided with a concave portion 54 and a convex portion 55 having the same arrangement and shape as the locking member 32 of the electronic device 9. Further, the communication target 53 is inclined upward as shown in FIG. 12B so that the locking member 32 by the electronic device 9 can be easily locked.

  Further, in the vicinity of the communication target 53, a communication method mark 52 and a communication lamp are provided in the same manner as the electronic device 9. In addition, the fixed device 50 can display the communication status display 40 on the display 51 by providing the proximity wireless communication control function and the communication state display function in the same manner as the electronic device 9 described above.

  As shown in FIG. 13, the locking member 32 (concave portion 33, convex portion 34) of the electronic device 9 is brought into contact with the locking member (concave portion 54, convex portion 55) provided in the fixed device 50. Both can be locked at the contact position. Therefore, it is possible to stabilize the positional relationship between the antennas disposed in the vicinity of the locking members of the electronic device 9 and the fixed device 50, and to execute close proximity wireless communication.

  FIGS. 14A, 14B, and 15 are diagrams showing an example of a fixed device 60 installed horizontally such as an HDD recorder. 14A shows a front view of the fixed device 60, FIG. 14B shows a top view of the fixed device 60, and FIG. 15 executes close proximity wireless communication between the electronic device 9 and the fixed device 60. It is a side view which shows the state in the case.

  As shown in FIG. 14B, the fixed device 60 that performs close proximity wireless communication with the electronic device 9 is provided with a locking member that is locked to the locking member 32 provided in the electronic device 9. A target 63 is provided on the upper surface side of the housing. The communication target 63 is provided with a locking member provided with a concave portion 64 and a convex portion 65 having the same arrangement and shape as the locking member 32 of the electronic device 9. Further, a communication method mark 62 and a communication lamp are provided in the vicinity of the communication target 63 in the same manner as the electronic device 9.

  As shown in FIG. 15, in the case of a fixed device 60 installed horizontally, the communication target 63 of the electronic device 9 is aligned with the communication target 63 of the fixed device 60 by arranging the communication target 63 on the upper surface portion. Thus, the locking member 32 (the concave portion 33 and the convex portion 34) of the electronic device 9 and the concave portion 64 and the convex portion 65 provided on the communication target 63 can be locked, respectively. By providing the communication target 63 on the upper surface of the fixed device 60, the electronic device 9 is simply placed together with the communication target 63, so that the proximity wireless communication can be executed in a stable state.

  In this manner, in the electronic device 9 according to the present embodiment, the concave portion 33 and the convex portion 34 of the locking member 32 provided on the communication target 30 are matched with the convex portion and the concave portion provided on other devices, respectively. Thus, the electronic device 9 and another device can be locked. Therefore, the positional relationship between the electronic device 9 and another device, that is, the positional relationship between the antenna 16a disposed in the vicinity of the communication target 30 and the antenna provided in the other device is stabilized without impairing operability. Can be made. Therefore, it is possible to stably execute and reproduce close proximity wireless communication with a limited communication distance.

  In the above description, the shape of the concave portion 33 and the convex portion 34 provided in the communication target 30 is described as being fixed, but may be changed according to the communication state of the proximity wireless communication. For example, the concave surface 33 and the convex portion 34 may be formed by making the flat surface uneven when the preparation for near field wireless communication is completed, and may be returned to the flat state when communication is completed. In this case, the communication target 30 is formed of a resilient member, and a mechanism unit that can change the member to a concave shape or a convex shape is mounted. By forming the concave portion 33 and the convex portion 34 according to the communication state of the close proximity wireless communication, the user can easily grasp the communication state.

  Further, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine a component suitably in different embodiment.
