Embodiment 1 of the present invention will be described below with reference to the drawings.
[Embodiment 1]
In the first embodiment, for example, an image formed with an image forming material having hydrophilicity and / or a recording medium having a predetermined pattern is removed and the recording medium is recorded by various recording methods. Applicable to playback.

  In addition, the first embodiment is suitable for removing the image forming material and reproducing the recording medium, for example, on the recording medium having an image and / or a predetermined pattern by the ink jet recording method. Therefore, the first embodiment will be described below by taking an inkjet recording system as an example of the recording system. First, the configuration of the recording medium 1 will be described.

<Recording medium>
FIG. 1 is a cross-sectional view showing an example of a recording medium 1 in the first embodiment. In the recording medium 1 shown in FIG. 1, an intermediate layer 20 is provided on one surface of a substrate (support) 10 having water resistance, and an image is formed on a surface of the intermediate layer 20 different from the surface on the substrate 10 side. A receiving layer 30 for receiving the forming material 40 is provided. The image forming material 40 has hydrophilicity.

(Substrate)
The substrate (support) 10 in the first embodiment is preferably water-resistant so that it does not change in quality due to the supply of a later-described image forming material removal solution (hereinafter also simply referred to as a removal solution). The substrate 10 includes a storage medium 50. The storage medium 50 is a wireless IC chip such as an RFID (Radio Frequency IDentification) tag. Hereinafter, the storage medium 50 will be described using an RFID tag as an example.

  When the RFID tag 50 is embedded in the substrate 10, the substrate 10 that does not impair the performance of the RFID tag 50 even when the removal liquid is supplied is preferable.

  As the substrate 10, high-grade printing paper, electrophotographic recording paper, thermal recording paper, and the like can be used. In particular, many reversible thermosensitive recording papers have a cured resin layer on the surface so that the recording layer can withstand repeated image formation and image erasure by a thermal head. Such reversible thermosensitive recording paper is preferably used as the substrate 10. be able to.

  As the substrate 10, either a transparent support or an opaque support can be used. The substrate 10 may have other layers such as an undercoat layer as desired.

  Although the thickness of the substrate 10 varies depending on the purpose of use, it is preferably 30 μm to 1000 μm, and more preferably 60 μm to 800 μm. The thickness varies depending on the usage, sheet size, material, and the like. For example, when the RFID tag 50 is embedded in the substrate 10, the thickness is normally relatively 600 μm to 800 μm.

  As described above, the substrate 10 may be a thermal recording medium, a thermal transfer recording medium, or the like, and the reversible thermosensitive recording medium as a typical example of this type of substrate 10 is the same as Japanese Patent Application No. 2010-. See 197395.

(Middle layer)
In the case of the recording medium 1 for inkjet, if the intermediate layer 20 is provided on the substrate 10, for example, a hydrophilic polymer material called latex or an aqueous emulsion coating solution of an inherently hydrophobic polymer material has been used. As a large amount of a strong emulsifier, there is a forced emulsion of an inherently water-insoluble resin due to surface activity.

  Thereby, strong adhesiveness with both the substrate 10 surface and the receiving layer 30 can be obtained, and prevention of beading and bleeding by the printed ink can be achieved. On the other hand, the harmful effects of using a large amount of strong emulsifier are already known. When a water-soluble resin coating solution is rarely used, it has been subjected to a crosslinking reaction treatment with a crosslinking agent having a functional group capable of chemically bonding with the constituent resin. In the prior art, it is natural that the appearance of strong adhesiveness is mainly taken into consideration, and it is not intended to delete the intermediate layer by applying water or an aqueous liquid.

  On the other hand, the intermediate layer 20 in Embodiment 1 contains as a main component an uncured water-soluble polymer material that dissolves or swells when the removal liquid is supplied. Here, “main component” means 60% or more by dry weight. The intermediate layer 20 of the recording medium 1 in Embodiment 1 is desired to have various subcomponents such as inorganic fine particles, organic fine particles, a small amount of a surfactant, an antioxidant, a leveling agent, etc., as long as the object of the present invention is not impaired. Can be contained.

  The water-soluble polymer material used for the intermediate layer 20 of the recording medium 1 in Embodiment 1 itself has a film-forming property and is excellent in the adhesion between the substrate 10 and the receiving layer 30, but is dissolved by supplying the removal liquid. Or it swells and reduces adhesiveness with the substrate 10. Adhesion with the receiving layer 30 is also significantly reduced, but this is not essential in the present invention. For the water-soluble resin used for the mid layer 20, refer to Japanese Patent Application No. 2010-197395 of the same applicant.

  Further, the intermediate layer 20 may receive ink (image forming material) that the receiving layer 30 could not accommodate. Therefore, the intermediate layer 20 is made of inorganic fine particles such as silica, titanium oxide, alumina, zinc oxide, calcium carbonate, acrylic, styrene, etc. in order to prevent further image dust and bleeding, and to maintain film hardness during drying. The resin fine particles may be added. When such inorganic fine particles are added, 1 to 50 parts by weight, preferably 1 to 20 parts by weight can be added to 100 parts by weight of the water-soluble resin.

  Further, the intermediate layer 20 may be subjected to an antistatic treatment such as a cationic surfactant as necessary in order to increase water permeability. The antistatic agent may be added to the material forming the receiving layer 30, or after forming the receiving layer 30, a solution dissolved and dispersed in an appropriate solvent may be applied. Furthermore, in order to prevent the intermediate layer 20 from being deteriorated, an ultraviolet absorber or an acid value inhibitor may be contained. The amount of the ultraviolet absorber or acid value inhibitor added is preferably 5% by weight or less.

(Receptive layer)
The receiving layer 30 in the first embodiment is for receiving ink droplets sent from the ink jet recording head suitably without forming a beading or bleeding and for forming an image. In this respect, there is essentially no difference from the ink receiving layer of glossy recording paper in ordinary ink jet. However, conventionally, a coating liquid containing a large amount of inorganic fine particles and organic fine particles that absorb the ink colorant and a small amount of binder resin for fixing them is applied and dried.

  On the other hand, the receiving layer 30 in the first embodiment also has sufficient water permeability (passability) to the intermediate layer 20 which is the lower layer in the process of removing the image forming material described later. The image forming material is, for example, a colorant for inkjet ink. In addition, the receptor layer 30 is disintegrated or relaxed in an adhesive state with the intermediate layer 20 by dissolution or swelling with the removal liquid of the intermediate layer 20.

  Also, the amount of inorganic fine particles and organic fine particles added is zero or very small compared to the case of the ink receiving layer of glossy recording paper in ordinary ink jet, and most of the material is preferably a resin. The technical idea is different from that of the ink receiving layer.

  The addition amount of the fine particles having a relatively large BET surface area for ink absorption is preferably conservative, and the layer thickness may be slightly thick accordingly. The amount added is, for example, 50 parts or less, preferably 30 parts or less, more preferably 25 parts or less per 100 parts of the binder resin.

  In the case of the first embodiment, the lower intermediate layer 20 receives the ink liquid that has penetrated into the receiving layer 30 and leaked from the receiving layer 30.

  The receiving layer 30 in the first embodiment includes a resin material that may include fine particles for absorbing and receiving an ink liquid for ink jet recording including a colorant. Further, it comprises an aqueous solution or an aqueous emulsion containing various auxiliary agents such as a stabilizer, a dispersant, a thickener, an antifoaming agent, an antioxidant, a wetting agent, an ultraviolet absorber, and a water-resistant agent, if desired. The receiving layer 30 may be formed as a coating layer of the coating agent. For detailed components of the receiving layer 30, refer to Japanese Patent Application No. 2010-197395 filed by the same applicant.

  The thickness of the receiving layer 30 is about 1 to 120 μm, preferably about 2 to 60 μm so that the ink absorbing action by the receiving layer 30 is sufficient and the forming operation of the receiving layer 30 can be performed satisfactorily. If the thickness is less than 1 μm, the effect of improving the environmental resistance such as water resistance, scratch resistance, weather resistance, etc. when formed into a film may be insufficient.

<Image forming material>
The image forming material 40 in Embodiment 1 contains a coloring agent and other auxiliary materials added as desired in the hydrophilic liquid medium. The colorant is, for example, various dyes and pigments included in a normal inkjet ink. For the ink composition used, see Japanese Patent Application No. 2010-197395 of the same applicant.

<Data input system>
Hereinafter, a case where the above-described recording medium 1 is used for a data input system will be described. FIG. 2 is a diagram illustrating an example of the recording medium 1 according to the first embodiment. In the recording medium 1 shown in FIG. 2, an image 70 and a predetermined pattern 60 are formed by the image forming material 40. The image 70 shows the process name “A-1”. In the image, a production model, a factory name, an assembly check sheet, and the like are also formed. The process name “A-1” 70 will be described as an example.

  In the example of the recording medium 1 shown in FIG. 2, the RFID tag 50 is embedded in the recording medium 1. The RFID tag 50 is configured to record and erase data. The RFID tag 50 stores predetermined data.

  A predetermined pattern 60 is formed on the recording medium 1 shown in FIG. The predetermined pattern is a pattern capable of recognizing writing data, and is, for example, a dot pattern (Anoto pattern) manufactured by Anoto. The handwritten data is handwritten characters or images, and is also called handwriting data.

  FIG. 3 is a diagram illustrating an example of the dot pattern 60 according to the first embodiment. The dot pattern 60 is, for example, a special dot pattern (so-called anoto pattern) in which dots are arranged at intervals of 0.3 mm in length and width. As shown in FIG. 3, the dot pattern 60 is composed of a combination of a total of 36 dots, 6 × 6 dots in length and width, arranged on a grid pattern with a spacing of 0.3 mm.

  FIG. 4 is a diagram showing the deviation of the dot pattern 60. As shown in FIG. 4, each dot is very slightly displaced from the perpendicular point in either the upper, lower, left, or right direction. Since each of the 36 dots has 4 positions, a huge number of patterns of 4 to the 36th power can be created.

  In order to form the dot pattern 60, it is necessary to form the dot pattern 60 with a high-resolution printer, but the recording medium 1 described above can be printed with a high-resolution printer. Therefore, the recording medium 1 can be formed even with the predetermined pattern 60 that requires high resolution. The predetermined pattern 60 is not limited to the Anoto pattern, and may be any pattern that can recognize the writing data.

<System configuration>
FIG. 5 is a diagram showing an example of a system for inputting data using the recording medium 1 of FIG. In the example shown in FIG. 5, the data input system includes a recording medium 1 and a writing device 300. It is also possible to construct an information management system using this data input system.

  The information management system includes an information processing apparatus (for example, a host computer) 100, a printer (for example, an ink jet printer) 200, a recording medium 1, a writing apparatus 300, and an RFID reader / writer 400. The RFID reader / writer 400 is installed at a work site. The RFID reader / writer 400 has an RFID antenna.

  The information processing apparatus 100, the printer 200, the writing apparatus 300, and the RFID reader / writer 400 can transmit and receive data via a network, respectively. The printer 200 includes an RFID reader / writer 201 that can write and read data to and from the RFID tag. The RFID reader / writer 201 has an RFID antenna.

  In the data input system in the first embodiment shown in FIG. 5, the recording medium 1 is used for process management of process “A-1” of the model “GX3300”. Hereinafter, the case where the person who performs this process “A-1” is “XXX” will be described.

  The RFID tag 50 stores information relating to the recording medium 1 or the storage medium 50, for example, “a” that is unique identification information (hereinafter also referred to as a unique ID). This data is sent from the information processing apparatus 100 to the printer 200, and the printer 200 writes the data to the RFID tag 50 of the recording medium 1 using the RFID reader / writer 201. Further, this data may already be stored at the time of factory shipment.

  When the printer 200 acquires data to be printed on the recording medium 1 from the information processing apparatus 100, the printer 200 prints images such as characters and photographs representing work processes, as shown in FIG. The image may be a barcode or the like. The printer 200 ejects ink (image forming material) from the recording head to print a predetermined pattern 60 on a part of the surface of the recording medium 1.

(Work contents)
Here, the work content will be described. When Mr. “XXX” performs the process “A-1” of the model “GX3300”, the recording medium 1 is held over the RFID reader / writer 400. The RFID reader / writer 400 reads the unique ID “a” stored in the RFID tag 50 of the recording medium 1.

  The read data is transmitted to the information processing apparatus 100, and the information processing apparatus 100 displays a work instruction corresponding to the process “A-1” corresponding to the unique ID “a” on the display screen. As will be described later, the information processing apparatus 100 manages the unique ID “a” and the work process “A-1” in association with each other. The work process “A-1” may be associated with a corresponding work instruction.

  Further, a display unit may be installed in the vicinity of the RFID reader / writer 400, and the display unit may display data read by the RFID reader / writer 400, the above-described work instructions, and the like.

  “XXX” assembles according to the work instructions displayed on the display screen, and when the work is finished, confirms the work according to the check sheet on the recording medium 1. When the confirmation of the check sheet is completed, Mr. “XXX” writes the worker name by handwriting in the column of the worker signature on which the predetermined pattern 60 is printed. In this case, the writing data is, for example, “XXX”. When the writing of the operator name is finished, the work standard is to press the transfer switch of the writing device 300.

  For this reason, when Mr. “XXX” finishes the work, the writing device 300 writes the worker name in the column of the worker signature on which the predetermined pattern 60 on the recording medium 1 is printed. The writing apparatus 300 can recognize writing data as image data. The writing device 300 can read data of the RFID tag 50. Next, the writing apparatus 300 will be described.

<Writing device>
FIG. 6 is a block diagram showing an example of the configuration of the writing apparatus 300 according to the first embodiment. A writing apparatus 300 illustrated in FIG. 6 is a pen type, and includes a reading unit 301, an RFID reader / writer 302, a pen-down detection unit 303, a data recording unit 304, a data transfer unit 305, a transfer switch 306, a clear switch 307, and a data processing unit 308. The writing unit 310 is provided.

The data transfer unit 305 is connected to the information processing apparatus 100 via a wireless or wired line.

  The reading unit 301 is provided at the tip of the writing apparatus 300, optically reads a predetermined pattern 60 on the recording medium 1, and accurately measures the trajectory to obtain writing data as image data. For example, the reading unit 301 uses the pen-down detection unit 303 to perform reading processing when the pen tip is in contact with the recording medium 1.

  The reading unit 301 is, for example, a small camera, and when writing a character, for example, a dot pattern 60 in a range of 1.8 mm square (6 × 6 dots in length and width = 36 dots in total as described above), for example, 75 sheets per second. Perform high-speed shooting. The reading unit 301 captures the position information (read data) on the dot pattern 60 that the writing apparatus 300 has passed through to reproduce the writing data as image data that has been scanned.

  The RFID reader / writer 302 includes an RFID antenna and reads data from the RFID tag 50 built in the recording medium 1. For example, the RFID reader / writer 302 reads the unique ID “a” from the RFID tag 50. The RFID reader / writer 302 functions as a writing unit that writes data to the RFID tag 50 and a reading unit that reads data from the RFID tag 50.

  The RFID reader / writer 302 writes the electronic data recorded in the data recording unit 304 into the RFID tag 50. In this case, the electronic data is stored in association with the unique ID of the RFID tag 50. The electronic data recorded in the data recording unit 304 is, for example, image data indicating a worker name, but is not limited thereto, and may be character data of a worker name subjected to OCR (Optical Character Recognition) processing.

  Thus, the electronic data of the writing data and the unique ID of the RFID tag 50 can be associated with each other and stored in the RFID tag 50. Therefore, the electronic data digitized by the writing apparatus 300 can be read from the recording medium 1 without accessing the information processing apparatus 100.

  The writing process of the RFID reader / writer 302 may be instructed by the transfer switch 306 or may be automatically performed after the reading process by the reading unit 301 is completed.

  The pen-down detection unit 303 detects whether or not the pen tip of the writing apparatus 300 is in contact with the recording medium 1. The pen-down detection unit 303 is, for example, a writing pressure sensor, and detects the presence or absence of contact between the pen tip and the recording medium 1 by measuring the writing pressure at the pen tip.

  Since the pen-down detection unit 303 only needs to detect contact between the pen tip and the recording medium 1, the pen tip may have a slight stroke in the direction along the pen axis, and a micro switch may be provided at the end thereof. realizable.

  The data recording unit 304 records electronic data of handwritten data generated by the reading unit 301. The electronic data is, for example, image data, but may be character data as long as OCR processing is possible in the writing apparatus 300.

  The data recording unit 304 is a memory having a predetermined capacity sufficient to record electronic data. The data recording unit 304 can also erase the recorded data. The trigger for erasing is when the clear switch 307 is turned on and a signal for erasing is acquired.

  The data transfer unit 305 is a communication unit that can transmit and receive data via a network. The data transfer unit 305 receives electronic data of handwritten data recorded in the data recording unit 304 and a unique ID “a” read from the RFID tag 50. Then, the information is transferred (transmitted) to the information processing apparatus 100. The trigger for transfer is when a transmission switch (not shown) is turned on and a signal for transfer is acquired.

  The transfer switch 306 is a switch that controls ON / OFF. When the transfer switch 306 is turned on, the data processing unit 308 outputs a signal for writing to the RFID reader / writer 302.

  The clear switch 307 is a switch that controls ON / OFF. When the clear switch 307 is turned on, the data processing unit 308 outputs a signal for erasing to the data recording unit 304.

  The transfer switch 306 and the clear switch 307 are provided in the writing apparatus 300 so as to be pressed, and are switched ON / OFF by the user. The data processing unit 308 controls the above units.

  The writing device 300 is housed in a cylindrical casing having a pen tip that enables writing on the recording medium 1 like a ballpoint pen or a magic, and operates with electric power supplied from a power source (not shown).

  The writing unit 310 is a unit for visualizing writing data, and is, for example, a pencil lead or a ballpoint pen. The tip of the writing unit 310 is the above-described pen tip. The user visualizes predetermined writing data on the predetermined pattern 60 using the writing unit 310.

  Here, as a specific example of the writing apparatus 300, there is Anotopen manufactured by Anoto. Anotopen realizes digitization of handwritten information, and can also record the writing order, writing speed, writing pressure, pen tilt, writing date and time.

  Note that the information processing apparatus 100 executes various document processing or document management using image data of writing data recorded in the writing apparatus 300. Next, the information processing apparatus 100 will be described in detail.

Further, the communication unit 111 receives the unique ID of the storage medium and / or electronic data of writing data from the RFID reader / writer 400, and transmits the unique ID of the storage medium and the print contents to the printer 200.

  The character recognition unit 112 can execute, for example, OCR processing. When the electronic data is image data, the character recognition unit 112 performs character recognition processing on the image data. The character recognition unit 112 performs character recognition processing on, for example, image data “XXX” and converts “XXX” into character data. When the character recognition process ends, the character recognition unit 112 outputs character data “XXX” to the mail creation unit 114.

  The management unit 113 manages the unique ID of the storage medium 50. One or a plurality of unique IDs are managed by the management unit 113. Here, the management unit 113 manages, for example, the unique ID, the work process, and the signed electronic data in association with each other. The management unit 113 may manage, for example, signed image data or character recognized character data as electronic data.

  When the management unit 113 acquires the character data “a” indicating the unique ID and the electronic data from the communication unit 111, first, the management unit 113 performs a collation process to check whether the character string “a” has already been managed. When the management unit 113 has already managed the character string “a”, the electronic data “XXX” is managed in association with the character string “a”. When the association of the electronic data “XXX” is completed, the management unit 113 notifies the mail creation unit 114 to that effect.

  When the character string “a” is not managed, the management unit 113 performs error processing. The error process is, for example, a process of notifying the writing apparatus 300 of an error, and the writing apparatus 300 is a process of notifying the user by turning on or blinking an LED (Light Emitting Diode) or the like when the error is notified.

  Thereby, when the management means 113 manages the signed electronic data, the process can indicate that the work has been completed, and can also manage who has done the work.

  The storage unit 115 stores address information that associates the user name with the mail address. For example, in the address information, a mail address of “XXX@yyy.com” is associated with the user name “XXX”. The address information holds one or more combinations of user names and mail addresses.

  When the management unit 113 receives a notification that the association of electronic data has ended, the mail creation unit 114 stores the character string “XXX” acquired from the management unit 113 or the character recognition unit 112 and the storage unit 115. It is checked against the user name in the address information.

  When the matching user name is found in the address information, the mail creating unit 114 creates a mail with the mail address corresponding to the user name as the destination. The mail text describes, for example, that the signature association has been completed. The mail creation unit 114 outputs a mail to the communication unit 111. The communication unit 111 transmits the mail created by the mail creation unit 114 to the destination.

  If there is no matching user name, the mail creating unit 114 performs error processing. The error process is, for example, a process of notifying the writing device 300 that the mail could not be transmitted, and activating the vibration function of the writing device 300 or turning on or blinking the LED.

  It should be noted that the error process when the electronic data cannot be associated may be different from the error process when the mail cannot be transmitted. For example, the LED may be turned on when electronic data is not yet stored, and the LED may be blinked when mail is not transmitted.

  As a result, the user can grasp which error processing is performed, and can easily take subsequent measures.

<Data example>
Next, various data will be described with reference to FIG. FIG. 9 is a diagram illustrating an example of each data in the first embodiment. FIG. 9A shows an example of data stored in the RFID tag 50. As shown in FIG. 9A, the RFID tag 50 stores a unique ID “a” for identifying the RFID tag when shipped from the factory.

  Next, when electronic data is written from the RFID reader / writer 302 of the writing apparatus 300, electronic data “XXX” is stored in the RFID tag 50 in association with the unique ID.

  FIG. 9B shows an example of data stored in the data recording unit 304 of the writing apparatus 300. As shown in FIG. 9B, the data recording unit 304 stores electronic data read by the reading unit 301.

  The unique ID of the RFID tag 50 may be read by the RFID reader / writer 302 and stored in the data recording unit 304. In this case, the data recording unit 304 stores the unique ID of the RFID tag 50 and electronic data representing the worker name.

  FIG. 9C illustrates an example of data managed by the management unit 113 of the information processing apparatus 100. Before the data transfer from the writing device 300, the unique ID and the process manage the data. When there is data transfer from the writing device 300 or another device (for example, the RFID reader / writer 400), the electronic data of the worker name “XXX” corresponding to the unique ID “a” is managed. The process data is not always necessary.

<Erase image>
The recording medium 1 described above can be initialized. When the recording medium 1 is initialized, it is necessary to erase an image printed on the recording medium 1, a predetermined pattern 60, writing data, and the like. Further, the data written in the RFID data 50 may be erased once and initialized.

  Next, an image erasing apparatus suitable for erasing the image of the recording medium 1, the predetermined pattern 60, and the data of the RFID tag 50 in the first embodiment will be described. FIG. 10 is a diagram illustrating an example of the configuration of the image erasing apparatus 500.

  The image erasing method of the recording medium 1 in Embodiment 1 includes a removing liquid supply process for supplying a removing liquid (removing liquid for an image forming material) having water or an aqueous liquid to the image holding surface of the recording medium 1, It includes a wiping process for wiping the image holding surface of the recording medium 1. These processes may proceed simultaneously, but are sequentially performed in the image erasing apparatus 500 shown in FIG.

  In the image erasing apparatus 500 shown in FIG. 10, the recording medium 1 is transported into the apparatus by a pair of transport rollers 501, and the removal liquid in the image material removal liquid tank 502 is pressurized at the location where the removal liquid is applied, and the liquid is ejected. Jetted from the nozzle 503 onto the surface of the recording medium 1.

  The liquid ejection nozzle 503 may be a nozzle array including a plurality of nozzle heads, or may be a slit type ejection head. The removing liquid is applied to the surface of the receiving layer 30 having the image forming material, and the intermediate layer 20 is swollen.

  Next, the recording medium 1 is guided to the rubbing process and brushed by the brush roller 508 while being held by the holding roller pair 506 and the holding roller pair 507. Thereby, the swelled intermediate layer 20 is removed.

  However, in the first embodiment, wiping with a woven cloth or the like may be used instead of brushing. A brush cleaning belt 509 shown in FIG. 10 removes paste-like debris attached to the brush roller 508.

  After that, in the example shown in FIG. 10, the recording medium 1 has the scraping material 511 with the help of the backup roller 510 to remove the remaining intermediate layer 20 material more completely. It is scraped off. Thereafter, the recording medium 1 is discharged onto the tray 513, but such a surface cleaning blade 511 is not necessarily required in the first embodiment.

  Further, the image erasing apparatus 500 includes an RFID reader / writer 512 that can write data to the RFID tag 50.

  The RFID reader / writer 512 erases the data of the RFID tag in the recording medium 1 from which the image or the predetermined pattern has been erased by the image erasing apparatus 500. In this case, the recording medium 1 is ejected to the tray 6513 in a state where there is no image or data of the predetermined pattern 60 and the RFID tag 50. As described above, the recording medium 1 after the image removal processing is only the substrate 10. The substrate 10 incorporates an RFID tag 50 as necessary.

<Reproduction of recording medium>
Next, reproduction of the recording medium 1 will be described. FIG. 11 is a diagram illustrating an example of the configuration of the regenerative coating apparatus 600. The reproduction coating apparatus 600 can reproduce the recording medium 1.

  As shown in FIG. 11, in the recording medium 1 having only the substrate 10 by the image erasing process, the intermediate layer 20 is coated on the substrate 10 having water resistance by the reproduction coating apparatus 600, and the intermediate layer 20 is dried. The

  After the intermediate layer 20 is dried, the reproduction coating apparatus 600 coats the receiving layer 30 for the image forming material 40 on the surface opposite to the substrate 10 side of the intermediate layer 20 and dries it. Thereby, the reproduction of the recording medium 1 is completed.

<Specific example>
Here, a specific example of a series of operations of image formation, image erasure, and reproduction of the recording medium 1 will be described. Depending on the model to be produced and each process, images such as characters, bar codes, photographs, etc. representing the work process are replaced, and the recording medium 1 is rewritten.

  Also, since the workers are different, it is necessary to erase written data written with a ballpoint pen or magic in the column of worker signatures. Further, since the layout printed on the recording medium 1 is also changed depending on the model and each process, the position and size of the predetermined pattern 60 are also changed as necessary.

  FIG. 12 is a diagram illustrating a specific example of a series of operations of image formation, image erasure, and reproduction. As shown in FIG. 12, the recording medium 1 changes to the states (1) to (6). Each state will be described using the surface of the recording medium 1 and the cross section of the recording medium 1.

  The state (1) indicates a state at the time of factory shipment, for example. The recording medium 1 in the state (1) has a substrate 10, an intermediate layer 20 on the substrate 10, and a receiving layer 30 on the intermediate layer 20. The RFID tag 50 at this time stores, for example, unique identification information (unique ID) of the RFID tag.

  The state (2) indicates a state in which an image (including the image 70) and a predetermined pattern 60 are formed by the image forming material 40 by the printer 200. For example, the image 70, the predetermined pattern 60, and the like are printed on the recording medium 1 by inkjet ink. At this time, the RFID reader / writer 201 of the printer 200 transmits data for recognizing the model to be assembled and data for recognizing the working process “A-1” corresponding to the unique ID of the RFID tag 50 at the time of printing. The tag 50 may be written. On the recording medium 1 of (2), the image 70 and the predetermined pattern 60 in the case of the process “A-1” are printed.

  The state of (3) indicates a state in which the work of the process “A-1” is completed and the name of the worker is written on the predetermined pattern 60 by the worker. Here, the name of the worker is “XXX”. At this time, the worker writes his / her name using the writing apparatus 300 described above.

  Thereafter, for example, the writing apparatus 300 writes the generated electronic data “XXX” in the RFID tag 50. As a result, the RFID tag 50 is associated with the unique ID and the electronic data.

  The state (4) indicates a state after the image erasing process is performed on the recording medium 1 in the state (3). When the work is completed on the recording medium 1 in the state (3) and the use is finished, image erasing for reusing the recording medium 1 is performed. The recording medium 1 is subjected to an image erasing process by the image erasing device 500 to erase the image 70, the predetermined pattern 60, and the like.

  Further, for example, data other than the unique ID is deleted by the RFID reader / writer 512 from the RFID tag 50 in the recording medium 1. Note that the unique ID may be deleted as necessary. At this time, the recording medium 1 is only the substrate 10.

  The state (5) indicates a state where the reproduction coating process is performed after the image is erased. In the recording medium 1 in the state (5), the intermediate layer 20 and the receiving layer 30 are reproduced on the substrate 10 by the reproduction coating process. As a result, the recording medium 1 returns to the state (1), is initialized for reproduction, and is reused.

  The state (6) shows a state where an image different from the state (2) and a predetermined pattern are printed. On the recording medium 1 of (6), the image 70 and the predetermined pattern 60 in the case of the process “A-2” are printed. The recording medium 1 of (6) is different from the recording medium 1 in the state of (2) in the size and position of the predetermined pattern 60 and the position of the image 70. Further, if the unique ID of the RFID tag 50 can be rewritten, it may be rewritten. As a result, the recording medium 1 can change the formed image, change the position and size of the predetermined pattern to be formed, and rewrite the unique ID according to the model and process contents. .

  In the recording medium 1 of (6), after the unique ID “b” is stored in the RFID tag 50, the operator name “YYY” is written on the predetermined pattern 60 by the writing device 300. Then, the same processing as the processing of “XXX” described above is performed. That is, the generated electronic data “YYY” is written to the RFID tag 50.

(Example of work)
Next, an application example of data input using the data input system according to the first embodiment will be described. FIG. 13 is a diagram illustrating an example of a work process. Here, an example is shown in which a container carrying a product goes through each process. RFID reader / writers 400 and 401 are installed for each process.

  For example, the worker “XXX” performs the work in the process “A-1”, and when the work is completed, signs the recording medium 1 using the writing apparatus 300 and moves the container to the next process.

  The worker “YYY” performs the work in the process “A-2”. When the work is completed, the worker “YYY” signs the other recording medium 1 using the writing apparatus 300 and moves the container to the next process. In this case, if each RFID reader / writer reads the RFID tag of the recording medium, it is possible to quickly grasp who is in charge of which work.

  For example, when an error inspection machine indicates that an operation in a predetermined process is an error when starting each operation, the RFID reader / writer transmits electronic data associated with the unique ID of the RFID tag corresponding to that process. read. The read electronic data is displayed on the display unit or output by voice so that the operator who has performed the error work can be easily identified without having to check the title column of the recording medium. Will be able to.

<Operation>
Next, the operation of the information management system in the first embodiment will be described. Hereinafter, an example of RFID preparation processing, an example of processing of a writing device, an example of data management processing of an information processing device, and an example of mail processing of an information processing device will be described in order.

(RFID tag preparation process)
FIG. 14 is a flowchart illustrating an example of RFID tag preparation processing according to the first embodiment. In step S101 shown in FIG. 14, the RFID tag 50 is numbered with a unique number and stores the number as a unique ID.

  In step S102, the information processing apparatus 100 manages the unique ID set (stored) in the RFID tag 50 in association with a work process or the like.

  Thereby, the information processing apparatus 100 can manage the unique ID of the RFID tag 50 included in the recording medium 1.

(Processing of writing device)
FIG. 15 is a flowchart illustrating an example of processing of the writing apparatus 300 according to the first embodiment. In step S <b> 201 illustrated in FIG. 15, the reading unit 301 determines whether or not writing data written on the predetermined pattern 60 is detected. When the reading unit 301 detects writing data, the reading unit 301 acquires image data of the writing data. If the reading unit 301 does not detect writing data, the process returns to step S201. When the reading unit 301 acquires the image data of the writing data, the reading unit 301 proceeds to step S202.

  In step S <b> 202, the data recording unit 304 stores electronic data of writing data generated by the reading unit 301.

  In step S203, the data processing unit 308 determines whether or not the clear switch 307 is turned on. The data processing unit 308 can determine that the clear switch 307 has been turned on when the push signal is acquired from the clear switch 307. If the clear switch 307 is ON (step S203—YES), the process returns to step S201. If the clear switch 307 is OFF (step S203—NO), the process proceeds to step S204.

  In step S204, the data processing unit 308 determines whether or not the transfer switch 306 is turned on. The data processing unit 308 can determine that the transfer switch 306 has been turned ON when the pressing signal is acquired from the transfer switch 306. If the transfer switch 306 is OFF, the process returns to step S203, and it is determined whether the clear switch has been turned ON during that time. If the transfer switch is turned on (YES in step S204), the process proceeds to step S205.

  In step S <b> 205, the RFID reader / writer 302 writes electronic data to the RFID tag 50.

  Thus, the writing apparatus 300 can associate the unique ID of the RFID tag 50 with the electronic data of the writing data (handwritten signature) using the RFID tag 50.

(Information management processing of information processing device)
FIG. 16 is a flowchart illustrating an example of information management processing of the information processing apparatus 100. In step S <b> 301 shown in FIG. 16, the communication unit 111 determines whether electronic data has been received from the writing apparatus 300. If electronic data is received (step S301-YES), it will progress to step S302, and if electronic data is not received (step S301-NO), it will return to step S301.

  In step S302, the management unit 113 reads the number of bytes determined from the top of the electronic data.

  In step S303, the management unit 113 searches the unique ID managed by itself for a match with the received character data of the unique ID.

  In step S304, the management unit 113 determines whether there is a matching unique ID. If there is a matched unique ID (step S304—YES), the process proceeds to step S305, and if there is no matched unique ID (step S304—NO), the process proceeds to step S306.

  In step S305, the management unit 113 stores electronic data (for example, image data) of the worker name in association with the matched unique ID.

  In step S306, the management unit 113 performs error processing. In the error process, an error notification is transmitted to the writing apparatus 300, and the writing apparatus 300 is a process of notifying the user of an error, for example, by turning on or blinking an LED or vibrating the LED.

  Thus, the information processing apparatus 100 manages the completion of the work by managing the electronic data of the worker name, and can also manage the worker name.

(Information processing device mail processing)
FIG. 17 is a flowchart illustrating an example of mail processing of the information processing apparatus 100. The process shown in FIG. 17 is a process performed after electronic data is associated (after step S305 shown in FIG. 16).

  In step S401 shown in FIG. 17, the character recognition unit 112 performs character recognition processing (OCR processing) on the received electronic data (image data) and converts it into character data. Here, the operator name is obtained as character data. If the electronic data is character data, step S401 is omitted.

  In step S <b> 402, the mail creation unit 114 searches the address information stored in the storage unit 115 for a user name that matches the worker name that has been character-recognized.

  In step S403, the mail creation unit 114 determines whether there is a matching user name. If there is a matching user name (step S403-YES), the process proceeds to step S404, and if there is no matching user name (step S403-NO), the process proceeds to step S406.

  In step S404, the mail creation unit 114 acquires a mail address corresponding to the matching user name from the address information, and creates a mail using the mail address as a destination. The mail text is, for example, a text notifying that the association of the image data has been completed.

  In step S405, the communication unit 111 transmits the mail created by the mail creation unit 114. As a result, the worker can know that the image data of his / her signature has been successfully managed by the information processing apparatus 100.

  In step S406, the mail creation unit 114 performs error processing. In the error process, for example, the writing apparatus 300 is notified that mail could not be transmitted. When the writing device 300 is notified that mail transmission is impossible, the writing device 300 lights or blinks the LED, or activates the vibration function. Note that this error processing may be different from the error processing associated with image data. Thereby, the worker can know that the mail could not be transmitted, and can know that the mail address should be registered in the information processing apparatus 100.

  As described above, according to the first embodiment, information relating to a recording medium and electronic data of information written on the recording medium can be associated with other than the host computer. Thereby, the electronic data of the information written on the recording medium associated with the information on the recording medium can be quickly confirmed. For example, electronic data can be confirmed from the recording medium 1 by storing the electronic data in association with the unique ID in the storage medium in the recording medium 1.

  In addition, when information written using a rewritable recording medium is rewritten, the electronic data of the written data stored in the RFID tag is updated using the writing device without accessing the host computer. It becomes possible to do.

  Further, according to the first embodiment, it is possible to re-form a predetermined pattern by forming a predetermined pattern capable of recognizing writing data on a recording medium capable of printing at a high resolution. Can do. The predetermined pattern can be formed in a predetermined size at a predetermined position on the recording medium.

  Further, even if the recording medium in the first embodiment is handwritten on a predetermined pattern, the written data can be erased. Further, the recording medium in the first embodiment can be printed by an ink jet printer capable of high resolution, and for example, minute dots such as an Anoto pattern can be formed.

In addition, the recording medium in the first embodiment includes a storage medium such as a wireless IC chip, thereby associating image data of data written on a predetermined pattern with information stored in the storage medium. become able to.
[Embodiment 2]
Next, the information management system in Embodiment 2 is demonstrated. In the information management system according to the second embodiment, the history identification information for identifying the history is provided so that the history of the data written in the storage medium (for example, RFID tag) of the recording medium can be understood. Image data is managed by giving history identification information to each data. The history identification information is also information representing the history of electronic data stored in the storage medium, such as a history number or alphabet.

  In the second embodiment, using the same reference numerals as those described in the first embodiment, the history identification number processing method of the writing apparatus 300, the data management method of the recording medium 1, and the data management of the information processing apparatus 100 are performed. How to do is explained. In the second embodiment, since the configuration and processing other than those described below are the same as those in the first embodiment, the description thereof is omitted.

<Writing device>
FIG. 18 is a block diagram illustrating an example of a configuration of the writing apparatus 300 according to the second embodiment. The writing apparatus 300 according to the second embodiment has the same configuration as that of the first embodiment except for the RFIF reader / writer 302, the data recording unit 304, the data transfer unit 305, and the changing unit 320.

  The data recording unit 304 has a storage area for storing history identification information for identifying the history of electronic data of handwritten data. The history identification information may be set in advance, or may be set by reading from the storage medium 50.

  The change unit 320 changes the history identification information held by the data recording unit 304 in order to distinguish electronic data of writing data stored in the storage medium 50 (for example, an RFID tag). For example, the changing unit 320 changes the value of the history identification information stored in the data recording unit 304 to a value different from this value.

  The changing unit 320 performs the changing process at any timing when writing data is read by the reading unit 301, electronic data of writing data is written to the RFID tag, or data is transferred by the data transfer unit 305. Do.

  The change unit 320 counts up the history number when the history identification information is a history number. For example, the changing unit 320 counts up the history number “00” to “01”. This change process is a process for giving history identification information indicating another value to the handwritten data read next.

  The RFID reader / writer 302 writes the electronic data and history identification information recorded in the data recording unit 304 into the RFID tag 50. In this case, the electronic data and the history identification information are stored in association with the unique ID of the RFID tag 50.

  The data transfer unit 305 transfers (transmits) the electronic data and history identification information of the writing data recorded in the data recording unit 304 and the unique ID read from the RFID tag 50 to the information processing apparatus 100.

  Note that the storage medium 50 (for example, an RFID tag) has a tag field through which communication can be received, and holds history identification information separately from an area where electronic data is recorded from the data recording unit 304.

<Information processing device>
The hardware and functions of the information processing apparatus 100 according to the second embodiment are basically the same as those according to the first embodiment, and therefore will be described using the same reference numerals. The second embodiment is different in that the information processing apparatus 100 manages history identification information.

  The information processing apparatus 100 acquires the history identification information together with the electronic data of the writing data and the unique ID of the storage medium 50 from the writing apparatus 300, and manages the unique ID, the electronic data, and the history identification information in association with each other. Thus, when electronic data related to the same unique ID is acquired a plurality of times, history identification information can be associated with each electronic data and left as history data.

<Data example>
Next, various data will be described with reference to FIG. FIG. 19 is a diagram illustrating an example of each data in the second embodiment. FIG. 19A shows an example of stored data stored in the RFID tag 50. As shown in FIG. 19A, the RFID tag 50 has a unique ID “a” for identifying the RFID tag and history identification information “00” (00) that indicates the history of written data at the time of factory shipment. (Initial value) is stored. Hereinafter, the history identification information will be described as a history number.

  Next, when the electronic data “XXX” and the history number “01” are written from the RFID reader / writer 302 of the writing device 300, the electronic data “XXX” and the history number “01” are associated with the unique ID in the RFID tag 50. Remembered. In this case, the history number stored in the data recording unit 304 is changed from “00” to “01” by the changing unit 320 of the writing apparatus 300.

  FIG. 19B shows an example of data stored in the data recording unit 304 of the writing apparatus 300. As shown in FIG. 19B, the data recording unit 304 stores electronic data read by the reading unit 301 and a history number changed at the time of reading.

  The RFID reader / writer 302 may read the unique ID of the RFID tag 50 and store it in the data recording unit 304. In this case, the data recording unit 304 stores the unique ID of the RFID tag 50 and the work. Electronic data representing the name of the person and a history number are stored.

  FIG. 19C illustrates an example of data managed by the management unit 113 of the information processing apparatus 100. The example illustrated in FIG. 19C illustrates data management when the second image data corresponding to the unique ID “a” is transmitted from the writing apparatus 300.

  In the example shown in FIG. 19C, the process, history (history identification information), and electronic data corresponding to the unique ID “a” and the unique ID “b” are managed. The history is, for example, a history number indicating the order when the same unique ID is transmitted. Here, it is assumed that the unique ID “a” and the electronic data “XXX” are transmitted from the writing apparatus 300 to the information processing apparatus 100 again.

  In the example shown in FIG. 19C, a history number is assigned to the electronic data corresponding to the unique ID “a” and managed. This is because the unique ID “a” has been transmitted twice from the writing device 300, the history numbers “01” and “02” are given, and the two electronic data transmitted together with the unique ID “a” are distinguished. Is done.

  Therefore, when the management unit 113 acquires electronic data of writing data corresponding to one unique ID a plurality of times, the management unit 113 associates history identification information (for example, a history number) with each electronic data of the writing data, and electronic data of the writing data. Manage your history.

<Operation>
Next, the operation of the information management system in the second embodiment will be described. Since the processing of the information processing apparatus 100 is the same as that of the first embodiment except that the history number is also managed, the description thereof is omitted.

(RFID tag preparation process)
FIG. 20 is a flowchart illustrating an example of RFID tag preparation processing according to the second embodiment. In step 501 shown in FIG. 20, the RFID tag 50 is numbered with a unique number, and the number is stored as a unique ID.

  In step S502, the RFID tag 50 prepares an area for storing history identification information separately from an area for storing a unique ID.

  In step S503, the information processing apparatus 100 can manage the unique ID set (stored) in the RFID tag 50 and the history identification information.

(Processing of writing device)
FIG. 21 is a flowchart illustrating an example of processing of the writing apparatus 300 according to the second embodiment. The processes in steps S601 to S604 shown in FIG. 21 are the same as the processes in steps S201 to S204 shown in FIG.

  In step S <b> 605, the RFID reader / writer 302 writes the electronic data and the history number recorded in the data recording unit 304 into the data processing unit 308 and also writes into the RFID tag 50.

  In step S <b> 606, the data processing unit 308 transmits the electronic data of the writing data, the history number, and the unique ID read by the RFID reader / writer 302 to the information processing apparatus 100 via the data transfer unit 305.

  In step S607, the changing unit 320 changes the history number stored in the data recording unit 304. For example, the changing unit 320 counts up the history number to the next number.

In addition, the history number is incremented, for example, by moving the history number stored in the data recording unit 304 to the history number of the next address.

  As described above, according to the second embodiment, when image data is transmitted a plurality of times for one unique ID, the information processing apparatus 100 can assign a history number and store each image data. it can. Also, the electronic data can be managed together with the history number on the RFID tag 50 side.

[Embodiment 3]
Next, the information management system in Embodiment 2 is demonstrated. In the information management system according to the second embodiment, the writing device is configured to be divided into writing means and position information acquisition means having a function as a reading unit.

<Example of data entry>
In the third embodiment, the method of data input is different from the above embodiment. FIG. 22 is a diagram illustrating an example of data input in the third embodiment. FIG. 22 is an enlarged view of the vicinity of the recording medium 1 shown in FIG.

  As shown in FIG. 22, the writing apparatus 700 is divided into writing means 710 and position information acquisition means 720. The writing means 710 is a pen, for example, and the position information acquisition means 720 is installed near the writing location of the writing means 710.

  In the example shown in FIG. 22, writing is performed on the dot pattern 60, but writing is not necessarily performed on the dot pattern 60. That is, in Embodiment 3, the dot pattern 60 may not be formed on the recording medium 1.

  In the example illustrated in FIG. 22, the position information acquisition unit 720 acquires infrared rays and ultrasonic waves generated from the writing unit 710. The position information acquisition means 720 reads written data using the acquired infrared rays and ultrasonic waves.

<Writing device>
FIG. 23 is a block diagram illustrating an example of a configuration of the writing apparatus 700 according to the third embodiment. The writing apparatus 700 according to the third embodiment includes writing means 710 and position information acquisition means 720. Note that in the writing apparatus 700, the same components as those in the above-described embodiments are denoted by the same reference numerals. In the following, differences from the above embodiment will be mainly described.

(Writing means)
The writing unit 710 includes a writing unit 310, a pen-down detection unit 303, a control unit 711, an ultrasonic generation circuit 712, and an infrared generation circuit 713. The writing means 710 has a function for visualizing writing data by the writing unit 310.

  When the pen-down detection unit 303 detects that the pen tip of the writing unit 710 is in contact with the recording medium 1 and is pressed, the pen-down detection unit 303 notifies the control unit 711 of an ON signal. The ON signal is notified to the control unit 711 while pen-down is detected.

  Upon receiving an ON signal from the pen-down detection unit 303, the control unit 711 applies a power supply voltage to the ultrasonic generation circuit 712 and the infrared generation circuit 713, and periodically generates an ultrasonic signal and an infrared signal. The ultrasonic signal and the infrared signal are generated while the ON signal is notified.

  On the other hand, when there is no notification of the ON signal from the pen-down detection unit 303, the control unit 711 stops supplying the power supply voltage to the ultrasonic generation circuit 712 and the infrared generation circuit 713, and stops generating the ultrasonic signal and the infrared signal. Let However, the generation start and stop timings of the ultrasonic signal and the infrared signal are not necessarily synchronized with the presence or absence of the ON signal.

  As a result, the writing means 710 generates an ultrasonic signal and an infrared signal while being written by the user using the writing means 710.

(Position information acquisition means)
The position information acquisition unit 720 includes a reading unit 721, an RFID reader / writer 302, a data recording unit 304, a data transfer unit 305, a transfer switch 306, a clear switch 307, and a data processing unit 308.

  The reading unit 721 includes an infrared light receiving unit 722, an ultrasonic wave receiving unit 723, an infrared ultrasonic wave measuring unit 724, and a coordinate calculation unit 725. As will be described later, the reading unit 721 receives a signal or light generated from the writing unit 710 during writing, and generates electronic data representing predetermined writing data based on a change in the received signal or light.

  The infrared light receiving unit 722 is an infrared sensor including, for example, an IrDA (Infrared Data Association) standard module. The infrared light receiving unit 722 receives the infrared signal generated from the infrared generation circuit 713, and generates a signal when the infrared signal is received. The infrared light receiving unit 722 can receive the received infrared signal without being blocked by providing an opening in the position information acquisition unit 720 or the like.

  The ultrasonic receiving unit 723 is an ultrasonic sensor using, for example, PVDF (Polyvinylidene Fluoride). Two ultrasonic receiving units 723 are provided at the left and right ends of the position information acquisition unit 723 in the longitudinal direction.

  The ultrasonic reception unit 723 receives the ultrasonic signal generated from the ultrasonic generation circuit 712, and generates a signal when the ultrasonic signal is received. The ultrasonic receiving unit 723 can receive an ultrasonic signal without being blocked by providing an opening in the position information acquisition unit 720.

  The infrared ultrasonic measurement unit 724 measures the time difference between the signal output from the infrared light reception unit 722 and the signal output from the ultrasonic reception unit 723. That is, the infrared ultrasonic measurement unit 724 measures each arrival time difference from the reception of the infrared signal to the reception of the ultrasonic signal.

The infrared signal flies at a speed of light of about 3 × 10 ⁸ m / s, while the ultrasonic signal flies at a speed of sound of about 3.5 × 10 ² m / s. Therefore, the arrival time from the writing means 710 for the infrared signal to the infrared light receiving section 722 is negligibly small with respect to the arrival time from the writing means 710 for the ultrasonic signal to the ultrasonic receiving section 723. Therefore, the infrared ultrasonic measurement unit 724 can use the measured arrival time difference as the flight time of the ultrasonic signal from the writing unit 710 to the ultrasonic reception unit 724.

  The coordinate calculation unit 725 calculates the position of the writing means 710 (pen) from the time difference measured by the infrared ultrasonic measurement unit 724 and reads the writing data. For example, the coordinate calculation unit 725 converts the flight time of the ultrasonic signal measured by the infrared ultrasonic measurement unit 724 into a flight distance, and the known distance between the flight distance and the two ultrasonic reception units 723. Is used to calculate the position coordinate data of the writing means 710 by the three-side survey method. The calculated position coordinate data (read data) may be recorded in the data recording unit 304 in association with the unique ID of the recording medium 1.

  The unique ID can be acquired using the RFID reader / writer 302 as described above.

  The data processing unit 308 may function as an image data generation unit, generate image data from the read data, and record the image data in the data recording unit 304. In this case, the image data recorded in the data recording unit 304 is transmitted by the data transfer unit 305, or the image data is written in the RFID tag 50 by the RFID reader / writer 302.

<Operation>
Next, the operation of the information management system in the third embodiment will be described. Processing different from the above embodiments will be described.

FIG. 24 is a flowchart illustrating an example of processing of the writing apparatus 700 according to the third embodiment. In step S701 illustrated in FIG. 24, the reading unit 721 determines whether or not writing data has been detected. For example, when the reading unit 721 receives an infrared signal or an ultrasonic signal, the reading unit 721 determines that the writing data is detected.

  If handwritten data is detected (step S701-YES), it progresses to S702, and if handwritten data is not detected (step S701-NO), it returns to step S701. In step S702, the data recording unit 304 records read data of handwritten data.

  In step S703, the data processing unit 308 determines whether the transfer switch 306 is turned on. The data processing unit 308 can determine that the transfer switch 306 has been turned ON when the pressing signal is acquired from the transfer switch 306. If the transfer switch 306 is OFF, the process returns to step S703. If the transfer switch is ON (step S703-YES), the process proceeds to step S704.

  In step S <b> 704, the RFID reader / writer 302 writes the read data to the RFID tag 50. Thereby, the reading data of handwritten data can be acquired using an ultrasonic signal or an infrared signal, and the unique ID of the RFID tag 50 can be associated with the reading data.

  In the operation of the third embodiment, numerical data such as position coordinate data is written to the RFID tag 50 as read data. However, the image data may be generated by the writing device 700 in the third embodiment and written to the RFID tag 50 as in the processing of the writing device 300 in the first and second embodiments. In the first and second embodiments, read data before image data generation may be written to the RFID tag 50 as in the third embodiment.

  Further, the position information acquisition unit 720 may transmit the read data stored in the data recording unit 304 and the unique ID read from the RFID reader / writer 302 to the information processing apparatus 100.

FIG. 25 is a flowchart illustrating an example of information management processing of the information processing apparatus 100 according to the third embodiment. In step S801 illustrated in FIG. 25, the communication unit 111 determines whether read data has been received from the writing apparatus 700. If read data is received (step S801—YES), the process proceeds to step S802. If read data is not received (step S801—NO), the process returns to step S801.

  In step S802, the management unit 113 has a function as an image data generation unit, and generates image data based on the position coordinate data of the read data. Note that the image data may be generated by another information processing apparatus having an image data generation unit.

  In step S803, the management unit 113 reads the number of bytes determined from the top of the received data. The head portion includes a unique ID.

  In step S804, the management unit 113 searches the unique ID managed by itself for a match with the character data of the received unique ID.

  In step S805, the management unit 113 determines whether there is a matching unique ID. If there is a matched unique ID (step S805-YES), the process proceeds to step S806, and if there is no matched unique ID (step S805-NO), the process proceeds to step S807.

  In step S806, the management unit 113 stores electronic data (for example, image data) of the worker name, for example, in association with the matched unique ID.

  In step S807, the management unit 113 performs error processing. In the error process, an error notification is transmitted to the writing apparatus 700, and the writing apparatus 700 is a process of notifying the user of an error by, for example, lighting or blinking an LED or vibrating the LED.

  In the operation of the third embodiment, the information processing apparatus 100 receives read data such as position coordinate data from the writing apparatus 700. However, as in the first and second embodiments, an image is stored in the writing apparatus 700. Data may be generated and the information processing apparatus 100 may receive the image data.

  In the first and second embodiments, as in the third embodiment, the information processing apparatus 100 receives read data before image data generation, and the management unit 113 has a function as an image data generation unit. Good.

  Thus, the information processing apparatus 100 manages the completion of the work by managing the electronic data of the worker name, and can also manage the worker name.

  As described above, according to the third embodiment, even if the writing device is divided into the writing means such as a pen and the position information acquiring means having the function of the reading unit, the same effect as the above-described embodiment can be obtained. Can do.
