First, a display holding medium (so-called electronic paper) that can be used in the present invention will be described.
Electronic paper is a medium in which an image is formed so that it can be rewritten in accordance with the external writing force and the formed image is displayed and retained even after the external writing force is removed. The device is connected in a chain, such as driving the device by directly applying external force, such as driving the device by changing the voltage accompanying light irradiation, or changing the coloration state by changing the pH of the liquid accompanying voltage application. Some use the display principle of driving.

As an example of electronic paper, electronic paper for rewriting an image by light irradiation (hereinafter referred to as optical rewritable electronic paper) will be specifically described.
The optical rewritable electronic paper includes an organic photoconductive material layer (organic photoconductive layer) 60 used in a copying machine, as shown in FIG. 11 showing a cross-sectional structure of the display unit 11 occupying most of the medium. Combined with a liquid crystal display material layer (microencapsulated cholesteric liquid crystal layer) 61, these layers are sandwiched between a pair of front and back transparent electrodes 62, and this laminate is sandwiched between a pair of front and back transparent substrate films 63. ing. In this configuration, the cholesteric liquid crystal layer 61 reflects white light, and the light is transmitted through the liquid crystal layer 61 and absorbed by the black layer 64 provided between the cholesteric liquid crystal layer 61 and the organic photoconductive layer 60. Black display monochrome image display is possible. Furthermore, since the cholesteric liquid crystal has a characteristic of interference-reflecting color light according to the helical pitch, the cholesteric liquid crystal layer 61 is configured by laminating liquid crystals with different helical pitches to realize color display with a simple structure. It is also possible.

  Then, the optical rewritable electronic paper displays an image to be transferred to, for example, a dimming element panel (light emitting panel) for image writing and projects it on the display unit 11 as shown in FIG. When a voltage is applied to the writing electrode provided on the display unit 11, the display unit 11 instantaneously converts the intensity of light into a reflection density and holds the projection image. The image information held in the display unit 11 can be erased by applying an erasing voltage to the electrodes, and the optical rewritable electronic paper can be reused many times by repeating writing and erasing. The optical rewritable electronic paper overwrites the image information held in the display unit 11 by applying a voltage to the electrodes and projecting a new image as described above without performing such an erasing process. It can be reused again and again by such overwriting.

As another example of electronic paper, electronic paper that rewrites an image by direct application of electricity (hereinafter referred to as “electric rewritable electronic paper”) will be specifically described.
As shown in FIG. 13 showing the cross-sectional structure of the display unit 11 occupying most of the medium, the electric rewritable electronic paper has fine colored charged particles (in the example shown, white particles 71 and black particles 72) at least on the surface. The electrode 73 is sealed between a pair of front and back electrodes 73 whose side is transparent, and is sandwiched between a pair of front and back film substrates 74 whose front side is transparent. An air layer is formed between the electrode layers 73 so that the colored particles 71 and 72 can freely move, and an insulating layer 75 for preventing contact with the colored particles 71 and 72 is provided on the matrix electrode layer 73. It has been. Note that a color display can be realized with a simple structure by using a color filter.

  The electric rewritable electronic paper is in a state in which no voltage is applied to the electrode 73 as shown in FIG. 14 showing the operating principle of the display unit 11 (however, the electrode 73 is charged to the polarity at the previous driving). The negatively charged white particles 71 accumulate on the back side, while the positively charged black particles 72 accumulate on the front side. When the display unit 11 is viewed from the front side, the display unit 11 is It becomes a black state. Then, when the driver connected to the electric rewritable electronic paper is operated based on the image data and the electrode polarity of the required part of the matrix of the display unit 11 corresponding to the image displayed by the function of the driver is reversed, the white particles The positional relationship between 71 and the black particles 72 is switched, and an image based on the contrast between the white particles 71 and the black particles 72 is displayed on the display unit 11. By operating the driver based on different image data, the image displayed on the display unit 11 can be switched depending on the contrast between the white particles 71 and the black particles 72 and can be reused many times.

FIG. 1 shows an outline of a document association system according to an embodiment of the present invention.
The document association system of this example includes a plurality of electronic paper (display holding medium) EP having an RFID tag, a reading device R having a pair of sandwiching units having an RFID reader / writer function, and a server (management) for managing document information Device) S.
Images of different electronic documents (documents 1 to 3) are displayed on the respective electronic papers EP1 to EP3, and information for specifying the actual data of the electronic document is stored in the RFID tag 13 of each electronic paper EP1 to EP3. It is recorded. Then, the information is acquired from each of the electronic papers EP1 to EP3 by overlapping them and sandwiched by the reading device R, and the actual data of the corresponding electronic documents are associated with each other by the server S.
In this example, the document association system is constructed using electric rewritable electronic paper. However, electronic paper based on other operating principles, such as optical rewritable electronic paper, may be used.

FIG. 2 shows a functional configuration of the document association system according to this example.
The electronic paper EP corresponds to a display unit 11 that displays and holds an image, a control unit 12 that controls the operation of the electronic paper EP, a memory 13 that stores a medium ID for identifying the electronic paper EP, and a sandwiching unit of the reading device R. Sensor 14 for detecting pressure applied to the medium portion to be used, power supply 15 for supplying power for operating the electronic paper EP, transmitter / receiver 16 for performing wireless communication processing with the reading device R, and used for the wireless communication processing An antenna 17 is provided.

  The reading device R includes a communication unit 21 that communicates with the server S, a control unit 22 that controls the operation of the reading device R, a power supply 23 that supplies power for operating the reading device R, and an electronic paper EP. A transmission / reception unit 24 that performs wireless communication processing and an antenna 25 used for the wireless communication processing are provided. In this example, the reading device R is configured as a dedicated device having the above-described functional units. However, for example, the reading device R may be configured by providing the functional units in an existing foldable mobile phone. Good.

  The server S holds a communication unit 31 that communicates with the reading device R, a control unit 32 that controls the operation of the server S, holds actual data of an electronic document, and holds related information that associates a plurality of actual data with each other. A document database 33; and a correspondence table 34 in which a medium ID of the electronic paper EP is associated with a document ID for identifying actual data of the electronic document (currently displayed electronic document) written in the electronic paper EP. ing.

  That is, in this example, since the actual data of the electronic document displayed on the electronic paper EP can be specified by referring to the correspondence table 34 based on the medium ID of the electronic paper EP, the medium ID is set to the electronic paper EP. Is stored in the electronic paper EP as specific information for specifying the actual data of the electronic document related to the display, and is used for the association processing of the actual data of the electronic document described later. For example, when an image of an electronic document is written in the electronic paper EP, a document ID for identifying the actual data of the electronic document is written and held in the electronic paper EP as specific information, and the association of the actual data of the electronic document is performed. It may be used for processing.

Next, actual data association processing of an electronic document will be described separately for processing on the electronic paper EP side and processing on the reading device R and server S side.
In this example, a flag indicating whether or not the electronic paper EP is sandwiched by the sandwiching portion of the reading device R is included in a part (for example, the end) of the medium ID stored in the memory 13 of the electronic paper EP. (Status information) is set, and, as will be described later, the state of the electronic paper EP at the time of acquisition is determined based on the flag of the medium ID acquired from each electronic paper EP. The medium ID that has been read from the electronic paper EP) that is not sandwiched is not used in the association process.

FIG. 3 shows a flow of rewriting processing of a flag (status information) in the electronic paper EP when the electronic paper EP is sandwiched by the reading device R.
Under the control of the control unit 12, the electronic paper EP determines whether or not the electronic paper EP is in a sandwiched state by the reading device R based on the pressure applied to the sensor 14 (steps S11 and S12). Then, in response to detecting the pressure exceeding the predetermined threshold value, the flag portion of the medium ID stored in the memory 13 is rewritten to a value indicating that the self is in the sandwiched state (step S13). After that, it is determined that the pinch is in a state of being detected during the detection of the pressure exceeding the threshold value, and the rewritten content is maintained (step S14), and the reading device R determines that the detected pressure falls below the threshold value. It is determined that the medium ID is released, and the flag portion of the medium ID is rewritten to a value indicating that the medium ID is not sandwiched (step S15).

FIG. 4 shows a flow of a reading process of a medium ID (specific information) in the reading device R when the reading device R sandwiches the electronic paper EP.
The reading device R obtains memory information (medium ID) of each electronic paper EP under the control of the control unit 12 in response to the plurality of electronic paper EPs being stacked and sandwiched by the sandwiching unit (step S21) (step S21). S22). Specifically, when a user presses a button provided on the reading device R with the electronic paper EP sandwiched therebetween, a request signal for the medium ID is transmitted by the transmission / reception unit 24 and the antenna 25, and each signal received is received. A medium ID returned from the electronic paper EP is received by the transmitting / receiving unit 16 and the antenna 17. In addition, for example, the request signal may be transmitted according to the pressure applied from the user to the sandwiching portion of the reading device R.

Thereafter, the reading device R refers to the flag portion of each acquired medium ID, and determines whether or not a plurality of medium IDs set with a flag indicating the pinched state are acquired (step S23). When a plurality of medium IDs to be acquired are acquired, they are collectively transmitted to the server S by the communication unit 21 (step S24).
When the server S receives a plurality of medium IDs from the reading device R, the server S specifies the actual data of the electronic document corresponding to each medium ID with reference to the correspondence table 34 under the control of the control unit 32, and specifies each specified Association processing for generating association information for associating actual data of electronic documents and storing them in the document database 33 is performed.
For example, all the acquired medium IDs may be transmitted to the server S without the flag determination by the reading device R, and the server S may perform flag determination and select the medium ID used for the association process.

FIG. 5 shows an example of related information data stored in the document database 33.
According to the figure, it can be seen that the actual data of the three electronic documents with document IDs “a12345”, “b34567”, and “c56789” are associated with each other with the date and time “2006/08/30 15:00”.

FIG. 6 is a diagram illustrating a display example of a result of searching for a related document related to a certain electronic document.
In the figure, the document ID “b34567” is specified as a search keyword to perform a search instruction, and the electronic documents “a12345” and “c56789” associated with the date and time “2006/08/30 15:00”, The electronic document “d00003” associated with the date “2005/10/15 18:00” is searched.

FIG. 7 shows another display example of the search result.
In FIG. 9A, a representation image representing each electronic document (in this example, an icon image) is displayed as a document group by superimposing it in units of related information, and one electronic document in the document group is a user. In response to the selection, other related information related to the electronic document is searched, and the representation image of the electronic document in the document group related to the other related information is displayed in a manner distinguished from the other. . Accordingly, as shown in FIG. 5B, information indicating which document group the selected electronic document belongs to is displayed.

Note that the reading device R of the present example has a function of erasing the display image of the electronic paper EP in response to the acquisition of the medium ID from the plurality of sandwiched electronic paper EPs. That is, since the user determines the association target after grasping the information displayed on each electronic paper EP, the information is no longer necessary for the user to browse at the time of association. The display is erased from the viewpoint of prevention. In addition, for example, an erasure button is provided in the reading device R, or whether or not to erase is switched according to the magnitude of the pinching pressure applied by the user so that the user can determine whether to erase or not. May be equal.
For example, as shown in FIG. 8, the reduced images of each erased image may be written and displayed in a list format on the uppermost electronic paper EP so that the associated contents can be confirmed on the spot.

  Here, in the electronic paper EP of this example, each function (mainly the function of the control unit 12) of the detection unit and the rewrite unit according to the present invention is configured by software. Further, in the reading device R of this example, each function (mainly the function of the control unit 22) of the acquisition unit and the transmission unit according to the present invention is configured by software. Further, the server S of the present example is configured by software with the function of the management means according to the present invention (mainly the function of the control unit 32).

  That is, each of the above functions is performed by each computer of electronic paper EP, reading device R, and server S having hardware resources such as a calculation unit such as a CPU (Central Processing Unit) and a storage unit such as a RAM (Random Access Memory). This is realized by executing the program according to the invention. Specifically, the program according to the present invention is stored in advance in a ROM (Read Only Memory) of the computer, the program is read out, expanded in the storage unit, and executed by the arithmetic unit. Each of the functional means is configured.

For example, the computer of the server S is provided with a medium connection portion such as a slot for loading an external storage medium such as a CD-ROM (Compact Disc Read Only Memory) or a memory cartridge so that the program according to the present invention can be read by the computer. The program may be read from the external storage medium stored and held by the medium connection unit and executed. Further, for example, a communication unit that performs communication with a program transmission device having a function of transmitting a program according to the present invention via a network is provided in the computer of the server S, and the program is received from the program transmission device by the communication unit. May be executed. Further, the program according to the present invention acquired from the outside as described above may be stored in a HDD (Hard Disk Drive) of the computer of the server S, and the program may be read from the HDD and executed.
Note that the electronic paper EP, the reading device R, and the server S may be configured with each functional unit according to the present invention by a dedicated hardware circuit instead of the software configuration as described above.

  In this example, the server S itself manages the actual data of the electronic document. For example, the server S does not manage the actual data of the electronic document, but is managed by another device connected to the network. Actual data of electronic documents (including Web documents) may be associated. Further, the actual data of the electronic document to be associated may be a unit of a partial element such as a page, an image, a figure, a sentence, etc. included in the electronic document, and the parts actually displayed on each electronic paper EP are associated with each other. Can do.

FIG. 9 shows an electronic paper EP and reading device R according to another embodiment of the present invention.
The electronic paper EP of this example does not have the power supply 15 and is supplied with operating power from the reading device R. That is, as shown in FIG. 5B, the sandwiching portion of the reading device R is provided with electrodes 26 for supplying operating power to each sandwiched electronic paper EP on each sandwiching surface. As shown in FIG. 1A, an electrode 18 configured to connect the medium front surface and the back surface of the electronic paper EP is provided at a portion corresponding to the position of the electrode 26 in the sandwiched portion of each electronic paper EP.
Accordingly, when a plurality of electronic paper EPs are stacked and sandwiched by the reading device R, operating power is supplied from the reading device R to each electronic paper EP.
This eliminates the need for the power source 15 from the electronic paper EP and simplifies the configuration. Also, since no power is supplied to the electronic paper EP that is not sandwiched, no specific information is transmitted from the irrelevant electronic paper EP. Can be prevented.

FIG. 10 shows an electronic paper EP according to still another embodiment of the present invention.
That is, the electronic paper EP of this example is obtained by the button 19 serving as a detecting means for detecting the pressure applied to the medium portion corresponding to the sandwiched portion of the reading device R, and the reading device R while detecting the pressure. And a switching element as connection means for connecting circuit wiring so as to form a circuit that enables acquisition of specific information.
Accordingly, since a plurality of electronic paper EPs are stacked and sandwiched between the reading devices R, the circuits of the respective electronic paper EPs are connected and acquisition of specific information becomes possible. Therefore, specific information is acquired from irrelevant electronic paper EPs. Is less likely to end up.
Further, by configuring the casing of the reading device R using a radio wave shielding article, the possibility of acquiring specific information from irrelevant electronic paper EP may be reduced.
