Description

  The present invention relates to a mobile device, and more particularly, to a technology that supports alignment with a counter device.

  Currently, mobile phones are becoming an indispensable tool in daily life from the viewpoint of information exchange and information collection. When mobile phones first appeared in the world, most of them had only a calling function. However, in recent years, like ordinary personal computers, it has become possible to send e-mails and connect to the Internet.

  In such a mobile phone market, smartphones are rapidly spreading in recent years. Smartphones do not have a keypad, but have a touchpad that detects contact on the display screen. When contact is detected on the touchpad, the same location on the display screen as the detected position can be selected and operated. It becomes. Portable devices having such a touchpad are not limited to smartphones but are also used in tablet terminals, digital cameras, portable game machines, and the like, and devices that can be charged in a non-contact state are also considered.

  In portable devices that can be charged in a non-contact state, the power generated in the charger is charged by receiving the built-in coil, so that the charger and the built-in coil face each other. It is necessary to align with the charger. However, when the charger has a sufficiently large area, the positioning of the portable device and the charger is easy, but when the portable device has a large area like a tablet terminal, the charger is on the back of the portable device. It may be difficult to align because it is hidden by the side. Moreover, in the thing with a large area like a tablet terminal, the location in which the coil was incorporated is difficult to understand. Although there is a standard for non-contact charging called “Qi”, since the charger and its corresponding devices are compatible with this standard, it has a tablet terminal with a large area and a charging smaller than that. It is thought that scenes using vessels will also come out.

  Here, it is an electronic device that can be charged in a non-contact state, and detects and informs the relative position to the charger by detecting the current flowing through the built-in coil and the magnetic flux density at a predetermined position. Technology has been considered (see, for example, Patent Documents 1 and 2). By using such a technique, it becomes possible to perform alignment between the charger and the portable device charged in a non-contact manner by the charger.

JP 2010-206866 A JP 2010-206865 A

  However, in the above-described technology, the relative position between the charger and the portable device is such that a certain amount of current flows through the coil in the portable device due to the electric power generated in the charger, or the magnetic flux Since the area for detecting the density needs to face the charger, if the charger and portable device are not in such relative positions, they can be aligned. It will disappear. That is, if the relative position between the charger and the portable device is not within a certain range, it is not possible to perform the alignment. Therefore, for example, in the case where the mobile device has a large area like a tablet terminal as described above, the charger is hidden behind the mobile device, so the relative position between the charger and the mobile device is charged. There is a problem that it becomes difficult to make the charger and the coil face each other, and it becomes impossible to align the charger and the portable device.

  The present invention has been made in view of the problems of the above-described technology, and when positioning the mobile device and the counter device, the counter device is hidden behind the back side of the mobile device. It is another object of the present invention to provide a portable device that can be easily aligned.

  Below, the algorithm of the control method of the portable apparatus comprised as mentioned above is demonstrated.

  FIG. 2 is a flowchart for explaining an algorithm of the portable device control method shown in FIG.

  In the mobile device 1 shown in FIG. 1, when the detection unit 2 comes into contact with the opposing device 5 facing the back surface of the mobile device 1, the position of the opposing device 5 is detected by the contact of the opposing device 5 (step 1).

  Next, the control part 3 produces | generates the relative position information of the opposing apparatus 5 and the predetermined location of the portable apparatus 1 based on the position of the opposing apparatus 5 which the detection part 2 detected (step 2).

  Then, the alerting | reporting part 4 alert | reports the relative position information which the control part 3 produced | generated (step 3).

  Below, a specific example is given and demonstrated about the portable apparatus 1 mentioned above.

  3A and 3B are diagrams illustrating a configuration example of a tablet terminal that is an embodiment of the mobile device 1 illustrated in FIG. 1, in which FIG. 3A is an external view viewed from the front side, and FIG. The external view seen, (c) is a configuration block diagram.

  As shown in FIG. 3A, the tablet terminal of this embodiment is provided with the touch panel 10 on the front surface of the housing 60, and on the back surface of the housing 60, the back touch pad 20 serving as the detection unit 2 shown in FIG. Is provided. The touch panel 10 is configured by superimposing a touch pad 11 on a display unit 12. The touch panel 10 is not limited to the touch pad 11 superimposed on the display unit 12, but may be an on-cell type or an in-cell type in which the touch pad 11 and the display unit 12 are integrated. Due to such a configuration, the touch panel 10 and the back touch pad 20 are opposed to each other via the housing 60 and have substantially the same shape as each other, so that the contact position of a finger or an object on the back touch pad 20 Can be displayed on the display unit 12 so as to be seen through the housing 60.

  The housing 60 is configured, for example, by fitting a front cover and a rear cover around it.

  The touch pad 11 and the back touch pad 20 have a conductive film (not shown) on the surface thereof, and a contact position where the finger or the object is in contact is determined by a change in capacitance between the conductive film and the finger or the object. To detect. Also, if the contact position where the finger or the object is in contact is detected, the resistance when the two conductive films are pressed by the finger or the object and in contact with each other is used in addition to the one using the capacitance described above. It may be based on a resistance film system that detects the position by detecting the value.

  The display unit 12 is composed of a liquid crystal, an organic EL, or the like, and performs display for performing an input operation by touching the touch panel 10. Further, the display unit 12 is configured such that, during the charging operation of the tablet terminal 100, an object that contacts the back touch pad 20 and a coil that is a predetermined location of the tablet terminal 100 based on the contact position detected by the back touch pad 20. The relative position information with respect to the part having the built-in 50 is displayed and output.

  Inside the housing 60, a CPU 30 serving as the control unit 3 shown in FIG. 1, a rechargeable battery 40, and a coil 50 serving as a power receiving unit are incorporated.

  The CPU 30 recognizes the contact position detected by the touch pad 11 or the back touch pad 20, and recognizes an input operation by contact with the touch pad 11 or the back touch pad 20 based on the recognized contact position trajectory. In addition, during the charging operation of the rechargeable battery 40, an object that contacts the back touch pad 20 and a coil 50 that is a predetermined location of the tablet terminal 100 are built in based on the contact position detected by the back touch pad 20. Generate relative position information with the part.

  The rechargeable battery 40 serves as a power source for the tablet terminal 100.

  The coil 50 receives electric power from an external coil by electromagnetic induction, and charges the rechargeable battery 40 by supplying current to the rechargeable battery 40.

  In addition to the above, the tablet terminal 100 is provided with a communication unit that controls communication, a voice input unit, and the like. However, these are not directly related to the present invention, and thus description thereof is omitted.

  Below, the operation | movement at the time of charge of the tablet terminal 100 comprised as mentioned above is demonstrated.

  4A and 4B are diagrams illustrating a state when the tablet terminal 100 illustrated in FIG. 3 is charged, in which FIG. 4A is an external perspective view, and FIG. 4B is a diagram illustrating a charging principle.

  When charging the tablet terminal 100 shown in FIG. 3, as shown in FIG. 4A, the tablet terminal 100 is placed on the charger 200 that is the opposite device 5 shown in FIG. 1. . Thereby, the back surface touchpad 20 of the tablet terminal 100 comes into contact with the charger 200.

  At this time, as shown in FIG. 4B, when the coil 250 built in the charger 200 and the coil 50 in the tablet terminal 100 face each other, the current flowing through the coil 250 causes the current between the two coils 50 and 250. As a result, electromagnetic induction occurs, a current flows through the coil 50, and this current is supplied to the rechargeable battery 40, whereby the rechargeable battery 40 is charged. Therefore, it is preferable to place the tablet terminal 100 on the charger 200 so that the coil 50 in the tablet terminal 100 faces the charger 200.

  In this embodiment, the tablet terminal 100 is placed on the charger 200 so that the coil 50 in the tablet terminal 100 faces the charger 200.

  FIG. 5 is a flowchart for explaining an example of an operation during charging of the tablet terminal 100 shown in FIG.

  When the tablet terminal 100 shown in FIG. 3 is placed on the charger 200 as shown in FIG. 4 and the back touch pad 20 of the tablet terminal 100 contacts the charger 200, the back touch pad 20 is charged. 200 contact positions are detected (step 11). The detected contact position is notified to the CPU 30, and the CPU 30 recognizes the contact position of the charger 200.

  The CPU 30 waits for detection of charging of the rechargeable battery 40 triggered by the detection of the contact of the charger 200 with the back touch pad 20 (step 12).

  Thereafter, when the CPU 30 detects charging of the rechargeable battery 40 by detecting the current flowing through the coil 50 or by detecting the current supplied to the rechargeable battery 40 (step 13), the CPU 30 displays the back touch pad. Based on the contact position of the charger 200 with respect to 20, the touch position information that is the relative position information between the rechargeable battery 40 and the part in which the coil 50 of the tablet terminal 100 is built is generated (step 14).

  The CPU 30 causes the display unit 12 to display and output the generated touch position information (step 15).

  FIG. 6 is a diagram showing a display state on the touch panel 10 during charging in the tablet terminal 100 shown in FIG. 3.

  First, as shown in FIG. 6A, the CPU 30 displays the coil position mark 13 indicating the position of the coil 50 as guidance information on the part of the tablet terminal 100 on the touch panel 10 in which the coil 50 is built.

  Further, as shown in FIG. 6B, the charger position mark 14 indicating the position where the charger 200 is in contact with the back touch pad 20 is displayed on the touch panel 10 as touch position information. Note that the touch panel 10 and the back touch pad 20 have substantially the same shape as described above, so that the charger position mark 14 indicating the position where the charger 200 is in contact with the back touch pad 20 is displayed on the housing. It is possible to display on the touch panel 10 while maintaining the relative position with respect to the outer shape of 60.

  When charging the rechargeable battery 40, the tablet terminal 100 is preferably placed on the charger 200 so that the coil 50 in the tablet terminal 100 faces the charger 200. Therefore, the tablet terminal 100 is shifted on the charger 200 so that the coil position mark 13 and the charger position mark 14 overlap each other. Then, as shown in FIG. 6C, when the coil position mark 13 and the charger position mark 14 overlap each other, the coil 50 in the tablet terminal 100 faces the charger 200.

  As described above, in the present embodiment, when the tablet terminal 100 is placed on the charger 200, the relative position between the rechargeable battery 40 and the part in which the coil 50 of the tablet terminal 100 is built-in is displayed on the touch panel 10. Therefore, the coil 50 in the tablet terminal 100 can be made to oppose the charger 200 only by shifting the tablet terminal 100 on the charger 200 based on this display.

  As an operation at the time of charging of the tablet terminal 100 shown in FIG. 3, it can be considered that the detection of charging is used as a trigger.

  FIG. 7 is a flowchart for explaining another example of the operation during charging of the tablet terminal 100 shown in FIG.

  When the tablet terminal 100 shown in FIG. 3 approaches the charger 200, electromagnetic induction occurs between the coils 50 and 250, and a current flows through the coil 50. When the CPU 30 detects this current (step 21), the CPU 30 Is triggered to detect charging of the rechargeable battery 40, and waits for detection of contact with the rear touch pad 20 (step 22).

  Thereafter, when the back touch pad 20 comes into contact with the charger 200 and the back touch pad 20 detects the contact position of the charger 200, the CPU 30 recognizes the contact position of the charger 200 (step 23). Based on the contact position of the charger 200 with respect to the back touch pad 20, the touch position information that is the relative position information between the rechargeable battery 40 and the part in which the coil 50 of the tablet terminal 100 is built is generated (step 24).

  The CPU 30 causes the display unit 12 to display and output the generated touch position information (step 25).

  In the above-described embodiment, the relative position information between the coil 50 of the tablet terminal 100 and the charger 200 is generated after the charging of the rechargeable battery 40 by the charger 200 is detected. Since the relative position information of the contact position of the charger 200 with respect to the back touchpad 20 and the coil 50 of the tablet terminal 100 is displayed on the touch panel 10, the charging of the rechargeable battery 40 by the charger 200 is detected. The relative position information may be generated regardless of the above. In that case, the charging mode for the rechargeable battery 40 may be designated by another input operation.

  Moreover, in embodiment mentioned above, although the relative position of the position of the coil 50 of the tablet terminal 100 and the contact position of the charger 200 with respect to the back surface touchpad 20 is displayed on the display unit 12, these relative positions are displayed. May be reported by sound such as voice or alarm, or vibration. When informing by voice, the tablet terminal 100 is connected to the charger 200 as “right”, “left” or the like so that the contact position of the charger 200 with respect to the back touchpad 20 overlaps the position of the coil 50 as guidance information. It is conceivable to indicate the direction of shifting upward. When reporting by alarm or vibration, it is conceivable to reduce the magnitude of the alarm or vibration as guidance information as the contact position of the charger 200 with respect to the back touchpad 20 approaches the position of the coil 50. Further, in the case of vibration, the period interval of vibration may be varied according to the distance between the contact position of the charger 200 and the position of the coil 50 as the guidance information.

  Moreover, in embodiment mentioned above, when charging the tablet terminal 100 using the charger 200, what controls so that the relative position of the tablet terminal 100 and the charger 200 may become a predetermined position is used. Although described as an example, the present invention is not limited to such non-contact charging, but performs non-contact communication between these recording media and a reader / writer, such as Felica and NFC. Also, the present invention can be applied to the alignment between the recording medium and the reader / writer.

  The constituent elements of the present invention are not limited to functions separated as shown in the above-described block diagram, and may be appropriately separated for each function.

  In addition, in the present invention, the processing in the portable device is recorded on a computer-readable recording medium that is a portable device in addition to the above-described dedicated hardware. The program recorded on the recording medium may be read by a portable device and executed. A recording medium that can be read by a portable device is an IC card, a memory card, or a removable recording medium such as a floppy disk (registered trademark), a magneto-optical disk, a DVD, or a CD, or a built-in processing device. Refers to HDD. The program recorded on this recording medium is read by a control block, for example, and the same processing as described above is performed under the control of the control block.
