A magnetic field is generated from the feeding coil 131 by sequentially flowing.

  The detection unit 150 monitors the inductance of each transmission coil 121 and each feeding coil 131. In response to the signal from the detection unit 150, the control unit 160 performs processing to identify the power supply coil 131 and the transmission coil 121 whose inductance changes significantly as a coil facing the power reception coil 231 and the reception coil 221. Then, the control unit 160 stores the identified transmission coil 121 and power feeding coil 131 in the storage unit 170 as coils used for signal transmission and power supply.

Sequentially generate a magnetic field. The detector 150 monitors the inductances of the transmission coil 121 and the feeding coil 131. When there is a corresponding coil, an induced magnetic field is generated, and the inductance detected by the detection unit 150 changes significantly. Thereby, the control unit 160 specifies the transmission coil 121 and the power supply coil 221 corresponding to the reception coil 221 and the power reception coil 231 of the electronic paper 200.
In the case of FIG. 5, the transmitting coil 121 corresponding to the receiving coil 221 is specified by the coil located at the coordinates (X16, Y9), and the feeding coil 131 corresponding to the power receiving coil 231 is specified by the coil located at the coordinates (X13, Y11). Will be.

By changing the magnitude of the inductance between the signal transmission coil (transmission coil 121 and reception coil 221) and the power supply coil (power supply coil 131 and power reception coil 231), the process of specifying the coil is performed simultaneously. It is also possible to do this. As means for changing the magnitude of the inductance, the number of turns or the diameter of the coil may be changed.
In addition, since the reception coil 221 is placed at an arbitrary relative position with respect to the transmission coil 121, it is desirable that the reception coil 221 is larger than the transmission coil 121 in order to reliably form the above-described magnetic field coupling. Similarly, the power receiving coil 231 is desirably larger than the power feeding coil 131.

  On the other hand, the wireless reception unit 195 receives a code signal read by the pen 300 via wireless communication. The control unit 160 reads out the processing operation requested by the user from the received code signal from the processing correspondence table of the storage unit 170, further reads out image data corresponding to this processing, and transmits it to the electronic paper 200 via the transmission coil 121.

Next, the identification information correspondence table 172 will be described.
FIG. 7 is a diagram showing the identification information correspondence table 172. The identification information correspondence table 172 as shown in this figure is stored in a predetermined area of the storage unit 170 in advance. In the identification information correspondence table 172, the identification information SID of all the transmission coils 121 provided in the signal transmission layer 120 and the center coordinates of each transmission coil 121 are described in association with each other. This center coordinate is represented by a two-dimensional XY coordinate determined on the placement surface 110 of the writing sheet 100. The identification information correspondence table 172 describes the transmission coil 121, but the power supply coil 131 also includes a similar correspondence table, and the description and illustration thereof are omitted.
The identification information correspondence table 172 has a field for describing the medium identification information MID. In an initial state, this field is blank, but when any of the transmission coils 121 receives a signal indicating the medium identification information MID from the reception coil 221, the control unit 160 corresponds to the identification information SID of the transmission coil 121. The received medium identification information MID is described in the field to be received.
In the example shown in the drawing, it is described that the identification information SID-288 of the transmission coil 121 corresponding to the reception coil 221 of the electronic paper 200 whose medium identification information MID is “MID-1” is the coordinate (X16, Y9). Yes.

FIG. 8 is a diagram showing the icon information correspondence table 173, and the icon information correspondence table 173 as shown in this figure is stored in a predetermined area of the storage unit 170 in advance. In this icon information correspondence table 173, icon group information AD1 to AD4 selected according to the image written on the electronic paper 200 or the overlapping state of the electronic paper 200 is stored.
For example, when the electronic paper 200 is placed alone on the placement surface 110 and the image written on the display unit 250 is one page of continuous data, an icon for specifying the next page, a return page An icon group for displaying an icon for designating, an icon for designating the first page, an icon for designating the last page, and the like are stored as icon group information. As described above, this icon information stores data for displaying a code together with a mark. For this reason, when an icon group is displayed on the display unit 250, a code is displayed together with each icon.
On the other hand, when the electronic papers 200 are overlapped, an icon group including an icon for enlarging a display image and an icon for copying an image displayed on the electronic paper 200 positioned below is added to the icon. It is stored as information.

(A-4: Structure of writing sheet and medium in communication state)
FIG. 9 is a diagram schematically illustrating a state in which the electronic paper 200 is placed on the placement surface 110 of the writing sheet 100.
As shown in the figure, the electronic paper 200 has a structure in which an insulating protective film (not shown), a signal receiving layer 220, a power receiving layer 230, a substrate 260, and a display unit 250 are laminated in order from the bottom. On the other hand, the writing sheet 100 has a structure in which an insulating protective film (not shown), a signal transmission layer 120, a switch layer 140 (140A, 140B), a power transmission layer 130, and a substrate 180 are laminated in order from the top. .
In this configuration, the signal transmission layer 120 and the signal reception layer 220 are arranged to face each other with an insulating protective film (not shown) interposed therebetween. Then, the coils provided in each of the signal transmission layer 120 and the signal reception layer 220 form magnetic field coupling to perform data communication. Furthermore, by sandwiching these two layers, the coils provided in each of the power transmission layer 130 and the power receiving layer 230 form magnetic field coupling, and wireless power transmission is performed from the power transmission layer 130 to the power receiving layer 230. Then, electric power is supplied to the electronic paper 200.

(B: Operation)
Next, the operation of the image processing system 1 will be described.
FIG. 10 is a sequence chart for explaining the operation flow of the image processing system 1.
As described above, since the electronic paper 200 has a memory property, the display state can be maintained even in a state where power is not supplied. Therefore, even after the power supply is stopped, the electronic paper 200 includes the last time the electronic paper 200 performed. The image written by the image writing process is displayed as it is.

The user places the electronic paper 200 on which the previous image is displayed on the placement surface 110 of the writing sheet 100. The control unit 160 of the writing sheet 100 detects the inductances of all the transmission coils 121 and the power supply coils 131 (step S1), and identifies the power supply coil 131 corresponding to the reception coil 221 and the power supply coil 131 corresponding to the power reception coil 231. Is performed (step S2).
Thereafter, the control unit 160 causes a current to flow through the identified transmission coil 121 to form a magnetic field coupling with the reception coil 221, and causes a current to flow through the identified power supply coil 131 to generate a magnetic field between the power reception coil 231. A bond is formed (step S3). Thus, the writing sheet 100 is ready for the writing process on the electronic paper 200.

  Next, the control unit 160 of the writing sheet 100 requests to transmit the medium identification information MID specific to the electronic paper 200 using magnetic field coupling (step S4). In response to this request, the control unit 210 of the electronic paper 200 reads the medium identification information MID from the storage unit 240 and transmits a signal corresponding to the medium identification information MID from the reception coil 221 (step S5). When the transmission coil 121 that has made the above request receives this signal, the control unit 160 describes the medium identification information MID corresponding to the received signal in the identification information correspondence table 172 in association with the transmission coil 121 (step 172). S6).

  On the other hand, the control unit 160 mathematically calculates the arrangement of the electronic paper 200 on the placement surface 110 from the identified transmission coil 121 and power feeding coil 131 and the coordinates of the four corners of the display unit 250 (step S7). . The coordinates are stored in the storage unit 170.

Next, the control unit 160 extracts an icon group from the icon information correspondence table 173 of the storage unit 170 based on the already displayed image or the arrangement state of the electronic paper 200 (step S8). At this time, the icon group designation region on the display unit 250 is also set to generate icon image data (details will be described in a specific example).
Then, the control unit 160 transmits the icon image data generated in step S8 to the electronic paper 200 via the transmission coil 121 and the reception coil 221 (step S9).

  The control unit 210 of the electronic paper 200 that has received the icon image data analyzes the image data and displays an icon group in the designated area (step S10). For example, in the case of FIG. 5, the icon group 250a as shown in FIG. 12 is displayed. In the drawing, only the mark is shown and the code display is omitted.

The user who sees the display of the icon group reads the code displayed together with the icon with the pen 300, and a reading signal representing the instructed icon is transmitted from the pen 300 to the wireless reception unit 195 of the writing sheet 100. (Step S11).
The control unit 160 of the writing sheet 100 reads processing corresponding to the icon designated by the user from the processing correspondence table, generates image data corresponding to this processing (step S12), and transmits it to the electronic paper 200. At this time, power necessary for rewriting is supplied from the power feeding coil 131 to the power receiving coil 231.
Then, the control unit 210 of the electronic paper 200 analyzes the received image data, and writes an image corresponding to the instruction of the icon on the display unit 250 (step S13).

(C: Specific example)
Next, processing until an icon is displayed on the display unit 250 of the electronic paper 200 by the image processing system according to the present embodiment will be described with a specific example.
<Specific example 1>
FIG. 5 and FIG. 11 illustrate the case where one electronic paper 200 is placed on the placement surface 110.
As shown in FIG. 5, when the electronic paper 200 is placed on the placement surface 110, the control unit 160 performs coordinates (X16) of the transmission coil 121 corresponding to the reception coil 221 of the electronic paper 200 by the coil specifying process in step S <b> 2. , Y9) and the coordinates (X13, Y11) of the power feeding coil corresponding to the power receiving coil 231, and the four corners of the display unit 250 on the placement surface 110 are represented by coordinates (X12, Y10), (X19, Y6), (X24, Y15), and (X17, Y19) are mathematically calculated.

  Next, the control unit 160 extracts an icon group from the image already displayed on the display unit 250. For example, in the case of one page portion of continuous data displayed on the display unit 250, an icon for specifying the next page, an icon for specifying the return page, an icon for specifying the first page, and the last page are displayed. Icon information for displaying a specified icon or the like is extracted from the icon information correspondence table 173. In addition, since there is no other overlapping electronic paper 200, position information having a predetermined area as a designated area is added to the icon information and generated as icon image data.

  Upon receiving the icon image data generated as described above, the electronic paper 200 displays an icon group 250a as shown in FIG. In this icon group 250a, four areas for instructing to jump to the first page, return to page, page forward or jump to the last page are displayed.

<Specific example 2>
Next, a case where two electronic papers 200A and 200B are placed on the placement surface 110 will be described with reference to FIGS.
The control unit 160 specifies the coordinates of the power supply coil corresponding to the transmission coil 121 and the power reception coil 231 corresponding to the reception coil 221 of the electronic paper 200 by the coil specification processing in step S2.
At this time, when the electronic papers 200 are sequentially placed on the placement surface 110, the specifying process is sequentially performed. Therefore, the electronic paper 200 in which the coil is specified first is positioned on the lower side, and the coil is later specified. It is determined that the electronic paper 200 in which is specified is positioned on the upper side.
On the other hand, when a plurality of electronic papers 200 are placed on the placement surface 110 at the same time, a large number of transmission coils 121 and power supply coils 131 are identified in the previous identification process. From the distance 231, the positions of the coils 221 and 231 (coils 121 and 131) in one electronic paper 200 are specified. However, in this case, it is impossible to determine whether the electronic paper 200 is up or down.

In the case of FIG. 11, the coordinates of the transmitting coil 121 corresponding to the receiving coil 221A of the electronic paper 200A are (X19, Y12), and the coordinates of the feeding coil 131 corresponding to the receiving coil 231A are (X15, Y12). The coordinates of the transmitting coil 121 corresponding to the receiving coil 221B are (X23, Y5), and the coordinates of the feeding coil 131 corresponding to the receiving coil 231B are (X20, Y5).
Further, the controller 160 determines that the coordinates of the four corners of the display unit 250 of the electronic paper 200A are (X14, Y11), (X22, Y11), (X22, Y21), (X14, Y21) by the arrangement detection process in step S7. It is mathematically calculated that the coordinates of the four corners of the display unit 250 of the electronic paper 200B are (X19, Y4), (X27, Y4), (X27, Y14), (X19, Y14).
Thereafter, the control unit 160 calculates that the coordinates of the area where the display units 250A and 250B overlap are (X19, Y11), (X22, Y11), (X22, Y14), and (X19, Y14). The area is replaced with the coordinates of the display unit 250.

  Next, when the upper and lower sides of the overlapping electronic papers 200 can be determined, the control unit 160 has an area where the display units 250A and 250B overlap. For example, the control unit 160 specifies an icon for specifying the next page and a return page. In addition to the icon for specifying the first page, the icon for specifying the first page, the icon for specifying the last page, an icon for enlarging the display image, and an icon for copying the image displayed on the electronic paper 200 positioned below. Is extracted from the icon information correspondence table 173. In addition, since the display unit 250 of the electronic paper 200 is overlapped, position information with the overlapped area as a designated area is added to the icon information and generated as icon image data.

  The control unit 160 transmits the generated icon image data to the reception coil 221A of the electronic paper 200A located on the upper side. Upon receiving the icon image data, the control unit 210 of the electronic paper 200 analyzes the icon image data, reflects the displayed icon group and the designated area on the display unit 250A, and performs a display as shown in FIG. . In this icon group 250b, four areas for instructing to jump to the first page, page back, page forward or jump to the last page, an icon for enlarging the display image, and the electronic paper 200 positioned below are displayed. Six areas of icons for copying the displayed image are displayed.

On the other hand, when it is difficult to determine whether the electronic paper 200 is up or down, such as when two electronic papers 200 are simultaneously placed on the placement surface 110, the control unit 160 applies the electronic paper 200 positioned on the lower side. The display of an icon for copying the displayed image generates icon image data deleted from the icon group. Then, the control unit 160 transmits, to each electronic paper 200, icon image data for displaying an icon group in an area where the display unit 250 overlaps.
As a result, the icon group is displayed in the overlapping area of each display unit 250. In addition, since the icon page return and page feed are set according to the image already displayed on each electronic paper 200, the function of copying the image displayed on the lower electronic paper 200 cannot be used. However, the image processing based on the already written image can be performed using icons displayed on each electronic paper 200.

(D: Effect of the embodiment)
According to the embodiment described above, power and image data are supplied from the writing sheet 100 to the electronic paper 200 no matter where the electronic paper 200 is placed on the placement surface 110 of the writing sheet 100. Thus, an image on the display unit 250 of the electronic paper 200 can be written. Therefore, the electronic paper 200 does not need to have a power source and does not need a nonvolatile storage means for storing image data.

  In addition, since the display content displayed on the electronic paper 200 is maintained even when power is not supplied, the display is maintained even if the user removes the electronic paper 200 from the writing sheet 100. Can be confirmed.

  Furthermore, since the electronic paper 200 displays a group of icons indicating processing based on the icon image data supplied from the writing sheet 100, the electronic paper 200 is provided with dedicated instruction means such as a key and a button. Therefore, it is not necessary to make the mechanism complicated, and a flexible icon arrangement can be performed according to the application. Therefore, the device configuration of the electronic paper 200 is simplified and the convenience can be improved.

  In this image processing system, an operation icon is displayed on the display unit 250 of the electronic paper 200 only by the operation of placing the electronic paper 200 on the placement surface 110 of the writing sheet 100. In addition, it is not necessary to operate the display unit 250 of the electronic paper 200 indirectly using another device, and the processing instruction such as image rewriting is performed via an icon, so that the processing instruction is intuitive. Can be done. Furthermore, in this system, since the user can instruct processing while viewing the directly displayed image, it is possible to prevent erroneous instructions and to perform processing such as image rewriting more easily and reliably.
