According to the present invention, based on electronic data input from the outside such as a personal computer, the output device registers the document electronic data in the management server in response to processing to display and hold the document image on the display recording medium. In addition, since the storage location information of the electronic data is held in the display recording medium, the display recording medium that displays and holds the document image can be associated with the stored electronic data of the document.
According to the present invention, the electronic data of the document displayed and held on the display recording medium can be accessed using the display recording medium holding the storage location information as a key, and the document registered in the management server Electronic data can be easily reused.

The present invention will be specifically described based on an example.
First, an example of a display recording medium used in the present invention will be described with reference to FIGS.
The display recording medium shown in the drawing is a medium called electronic paper, and is roughly divided according to the document image recording method, and is classified into an optical writing type shown in FIGS. 6 to 9 and a self-writing type shown in FIGS. There is a thin device like paper so that it can be called so-called electronic paper.

6A shows the optical writable electronic paper EP as viewed from the front, and FIG. 6B shows the optical writable electronic paper EP as viewed from the side. The electronic paper EP shown in the figure has a display unit 2 for displaying and holding a document image and a processing unit 3 for managing electronic data. In FIG. The functional part is also shown.
The optical writable electronic paper EP is a flexible thin thin film, for example, as large as A4 size paper, and the processing section 3 is provided on one piece of the display section 2 that occupies most of the area. In addition, the magnitude | size of the display part 2 is arbitrary, can also be used as a tag or a card | curd, and shall be the magnitude | size according to a use.

As will be described later, the processing unit 3 includes an electrode 4 for applying a voltage for driving the display unit 2, a wireless unit 5 for wireless communication with the outside, a memory 6 for holding electronic data in a readable and writable manner, and a wireless unit 5. A battery 7 for supplying driving power for the memory 6 is also provided.
The optical writable electronic paper EP stores document data by wirelessly communicating with a device having an external wireless communication function (an output device for registration, which will be described later, an output device for displaying a screen or holding a display) by the wireless unit 5. Electronic data such as location information can be transmitted and received, and these electronic data can be held in the memory 6.

For example, as shown in FIG. 7, the optical writable electronic paper EP displays a document image on the liquid crystal panel 25 based on the electronic document data, and applies voltage from an external power source to the electrode 4 while applying the voltage from the external power source. By irradiating light on the liquid crystal panel 25, the document image displayed on the liquid crystal panel 25 can be transferred to the display unit 2 and displayed and held.
That is, the optical writable electronic paper EP transfers the projected image information to the display unit 2 by applying a voltage to the electrode 4, and holds the image information in a display state even after the voltage applied to the electrode 4 is removed. It has the function to continue.

  The optical writable electronic paper EP includes an organic photoconductive material layer (organic photoconductive layer) 20 and a liquid crystal display material layer used in a copying machine, as shown in FIG. (Microencapsulated cholesteric liquid crystal layer) 21 is combined, these layers are sandwiched between a pair of front and back transparent electrodes 22, and this laminate is sandwiched between a pair of front and back transparent substrate films 23. In this configuration, the white display in which the cholesteric liquid crystal layer 21 reflects light and the light is transmitted through the liquid crystal layer 21 and absorbed by the black layer 24 provided between the cholesteric liquid crystal layer 21 and the organic photoconductive layer 20. 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, color display can be realized with a simple structure by forming the cholesteric liquid crystal layer 21 by laminating liquid crystals having different helical pitches. It is also possible.

  The optical writing type electronic paper EP displays an image to be transferred to, for example, a light control element panel (light emitting panel) 25 for image writing and displays the display unit 2 as shown in FIG. When the voltage is applied to the electrode 4, the intensity of light is instantaneously converted to the reflection density and the projection image is held. The image information held in the display unit 2 can be erased by applying an erasing voltage to the electrode 4, and the optical writable electronic paper EP can be reused many times by repeating writing and erasing. Note that the optical writing type electronic paper EP does not perform such an erasing process, but applies the voltage to the electrode 4 as described above to project a new image, whereby the image information held in the display unit 2 is stored. Can be overwritten and can be reused again and again by such overwriting.

Therefore, the optical writing type electronic paper EP has the property of holding the image information transferred by projecting the image without power in addition to the property of being thin and flexible like paper, so that it is used for a printer or a copying machine. It is a display recording medium that can be used like paper and can be reused repeatedly. Furthermore, since the optically writable electronic paper EP of this example has a wireless communication function and a memory function, as will be described later, electronic data (such as document data storage location information) recorded in the memory 6 is contactless. Can be sent and received.
Note that the output device for registration and the output device for screen display and display holding, which will be described later, apply a voltage to the electrode 4 as described above when using the optically writable electronic paper EP as a display recording medium. Thus, it has a function of projecting a document image on the display unit 2, a function of transmitting and receiving storage location information stored in the memory 6, and the like.

Electronic data such as document data can be transmitted and received, and the electronic data can be held in the memory 16.

Further, the self-writing type electronic paper EP is different from the optical writing type electronic paper EP, and the driver 14 displays a document image on the display unit 12 based on the electronic document data held in the memory 16, and the operation unit 18. The document image to be displayed can be switched and changed in accordance with the operation input from, and the display unit 12 has a function to keep the document image in the display state even if the driving power of the driver 14 is removed.
The self-writing type electronic paper EP is a fine colored particle (white particles 31 and black particles 32 in the illustrated example) used as toner in a copying machine, as shown in FIG. Is sealed between a pair of front and back electrodes 33 whose surface side is transparent, and is sandwiched between a pair of front and back film substrates 34 whose surface side is transparent. An air layer is formed between the electrode layers 33 so that the colored particles 31 and 32 can freely move, and the matrix-like electrode layer 33 is provided with an insulating layer 35 that prevents contact with the colored particles 31 and 32. It has been. Note that a color display can be realized with a simple structure by using a color filter.

 The self-writing type electronic paper EP is in a state in which no voltage is applied to the electrode 33 as shown in FIG. 11 showing the operation principle of the display unit 12 (however, the electrode 33 is charged to the polarity at the previous driving). ), The negatively charged white particles 31 accumulate on the back side, while the positively charged black particles 32 accumulate on the front side. When the display unit 12 is viewed from the front side, the display unit 12 is observed. Becomes a black state. Then, when the electrode polarity of the required portion of the matrix corresponding to the image information displayed by the operation of the driver 14 based on the document data is inverted, the positional relationship between the white particles 31 and the black particles 32 is switched, and the display unit 12 is switched. A document image based on the contrast between the white particles 31 and the black particles 32 is displayed. By operating the driver 14 based on different document data, the document image displayed on the display unit 12 can be switched depending on the contrast between the white particles 31 and the black particles 32, and can be reused many times. .

Accordingly, the self-writing type electronic paper EP has the property of holding the image information displayed on the display unit 12 with no power supply in addition to the property of being thin and flexible like paper, so that the display can be used like paper. It is a recording medium. Further, since the self-writing type electronic paper EP of this example has a wireless communication function and a memory function, as will be described later, electronic data (such as storage location information of document data) recorded in the memory 16 is contactless. Can be sent and received.
Note that the output device for registration and the output device for screen display and display holding, which will be described later, display and hold on the display unit 12 as described above when the self-writing type electronic paper EP is used as the display recording medium.

Here, regardless of the optical writing type or the self writing type, the wireless communication function such as the wireless unit 5 (15) and the memory 6 (16) and the memory function unit are displayed on the electronic paper as shown in FIG. The wireless IC tag (RFID) 41 may be configured separately from the unit 2 (12), and the RFID tag 41 may be attached to the electronic paper EP so as to have the same configuration as described above. In the case of a wireless IC tag, the battery may be a capacitor that holds an electromotive force from the tag reader.
In addition, since the recording unit of the display recording medium according to the present invention mainly stores the storage location information of the document data displayed and held on the display unit 2 (12), the RFID 41 A barcode 42 in which the storage location information is two-dimensionally encoded is printed or pasted on an electronic paper EP by a registration output device described later, and the barcode 42 is imaged by a screen display or display holding output device described later. You may make it read.

In addition, the present invention can be applied to electronic papers other than formats such as self-writing type electronic paper and optical writing type electronic paper. For example, the electronic paper can be loaded into an external rewriting device and the display unit can be self-writing type. The document image may be written electronically. That is, the self-writing electronic paper is an example of an electronic paper that does not require an external image writing device, and the optical writing electronic paper is an example of an electronic paper that requires an external image writing device. .
In addition, as the display unit 2 (12) of the electronic paper EP, a liquid crystal having a memory property typified by a ferroelectric liquid crystal, an electrophoretic method in which a charged particle is moved to switch a display, and a charged particle is rotated. Alternatively, a particle rotation method for switching the display, a magnetophoresis method for switching the display by moving particles by magnetism, a thin battery-driven thin liquid crystal or an EL element may be used.

  In addition to the electronic paper as described above, the present invention can also be applied to a paper P that is a paper medium. When the paper P is used as a document image display recording medium, a registration output device described later is used. The display holding output device may have a function of printing a document image on the paper P based on electronic data, such as a known printer or copying machine. For example, as shown in FIG. 14, the registration output device may store the RFID tag 41 that holds the storage location information as described above. The dimension code 42 may be pasted or printed on the paper P, and the storage location information may be read from the RFID tag 41 or the two-dimensional code 42 in the display holding output device.

And a function of transmitting storage location information data or adding a storage location information code to the electronic paper EP.

The management server 60 includes storage information providing means 61, registration means 62, and a database memory 63 configured by executing a program with a dedicated functional device or computer resource.
The management server 60 starts the registration process when the document electronic data is acquired from the registration output device 50, but the registration unit 62 stores the acquired document data in the database memory 63 to register it, and the storage location of the document data The storage information providing means 61 provides the registration output device 50 with a URL as information indicating (that is, the storage location).

That is, as shown in FIG. 2, the database memory 63 identifies and manages each registered document data by assigning a document ID (URL in this example), and uses the URL (that is, storage location information). Each registered document data can be specified.
In this example, in addition to document data in the original format acquired from the registration output device 50, document data and thumbnail image data in a general format generated by converting the original data are also registered. For this reason, the registration means 62 has a conversion means 64, which converts the document data in the original format into a general-purpose document data with low application dependency and a reduced version of the document image. Generate thumbnail image data.

In this example, the document data entity is recorded in the database 63. However, the registration unit 62 stores the document data entity in another data server on the network, and the management server 60 database stores the document data ID and ID. The address of the data server that stores the document data entity may be recorded.

And a function of transmitting storage location information data or adding a storage location information code to the electronic paper EP ′.

  Here, when document data in general-purpose format or thumbnail format is registered in addition to the original format as in this example, the management server 60 provides it to the display holding output device 70 in response to the data acquisition request. The document data may be a data set of any one of these formats or a plurality of these formats. For example, if the general-purpose document data is set to be provided in response to the data acquisition request, the document data provided even when the display holding output device 70 does not have an application corresponding to the original data. Based on the above, it is possible to perform processing for displaying and holding the document image on the electronic paper EP ′. Further, for example, if the thumbnail image data is set to be provided in response to the data acquisition request, the display holding output device 70 is based on the provided thumbnail image data even when the document data includes a plurality of pages. Thus, it is possible to perform processing for displaying and holding document images for a plurality of pages in a thumbnail list on the display unit of the electronic paper EP ′.

  In this example, document data in a format suitable for the output device 70 may be provided by using the conversion means 64 provided in the management server 60. That is, the output device 70 manages the data format that can be processed by itself, the data acquisition unit 72 transmits a data acquisition request including specific information of the processable data format to the management server 60, and the conversion unit 64 The original format document data is converted into the requested format and provided to the output device 70. As a result, when there are a large number of output devices 70, a clear document image can be displayed and output in an optimum format regardless of which output device is used.

  By displaying and holding the document image on the electronic paper EP ′ as described above, it becomes easy to browse the document based on the electronic data by copying, but the storage location information of the document data is also newly output. Since (URL) is held so as to be externally readable, it is possible to display and hold a document image on another display recording medium based on document data using the electronic paper EP ′ as described above. That is, a document image can be displayed and output by accessing document electronic data using the electronic paper as a key, and any output device that can access the management server 60 can use the same document.
