The purpose of this print medium management system is to manage a print medium and an electronic medium in association with each other by a personal computer (hereinafter referred to as “personal computer”). A print medium is a sheet on which an image is printed. The electronic medium corresponds to paper (print medium) and is an electronic file created inside the personal computer. The contents of the electronic file are the same as the print contents of the print medium. One page of electronic medium corresponds to one electronic file. In addition, image data indicating the appearance of the paper corresponding to the electronic file (hereinafter referred to as “paper image”) is also stored.
The specific operation of the print media management system is to display a paper image corresponding to the upper one of the stacked sheets on the top of the display, or to correspond to the order in which the sheets are stacked. Is displayed on the display unit, or when separated papers are aligned, the corresponding paper images are aligned.

As shown in FIG. 1, the print medium management system 100 includes a wireless sheet 10 attached to a predetermined position of a sheet P that is a print medium, and a personal computer 20 that is a management apparatus. The method of attaching the wireless sheet 10 to the paper P may be pasting.

The ROM 30C transmits / receives radio signals to / from the wireless sheet 10 via the transceiver 21, and displays a sheet image on the display unit 24 according to the arrangement state of the sheet P. And a program for analyzing an identification ID and a measurement result from a signal transmitted from the wireless sheet 10 are stored. The RAM 30D is used as a work area when executing the program. In addition, in the storage area 30E, as shown in FIG. 2, a correspondence table TA in which the identification information of the electronic file / paper is associated with the identification ID of each sensor, the identification information of the electronic file / paper, and the measurement result of each sensor. Is stored in the sensor table TB and the like.

(1-2) Configuration of Radio Seat Next, the radio seat 10 used in the first embodiment will be described.
As shown in FIG. 3, the wireless sheet 10 attached to the paper P includes an optical sensor 101, a pressure sensor 102, and an acceleration sensor 103. There is no particular position regarding the arrangement of the sensors, but due to its characteristics, at the position where the sensor is attached to the paper P, the acceleration sensor 103 is outside the paper P where the influence of acceleration is large, and the optical sensor 101 is at the stage where the paper P overlaps. Are arranged so as to be inside the paper P which is easy to overlap.

Further, from the measurement result of the pressure sensor 102 attached to the paper P, the order of the plurality of stacked paper P can be detected. Further, from the detection result of the acceleration sensor 103 attached to the paper P, it can be detected that a plurality of papers P are aligned.
The wireless sheet 10 accommodates the sensors 101 to 103 in a sheet-like package made of a resin material or the like, and a button portion 10A is formed integrally with the package. The button unit 10 </ b> A transmits externally applied pressure to the pressure sensor 102.

Here, the correspondence table TA shown in FIG. 2A associates the identification ID of each sensor with the identification information of the electronic file / paper. Each sensor has an identification ID, and has identification IDs for three sensors for one sheet P (one wireless sheet 10). When the paper image is printed, the correspondence is stored in the correspondence table TA in association with the paper identification information, the electronic file (paper image) identification information, and the identification ID of each sensor.
Specifically, in this correspondence table TA, OID1, PID1, and AID1, which are identification IDs of the sensors, correspond to the paper P1 and the electronic file EP1, and the identification IDs of the sensors correspond to the paper P2 and the electronic file EP2. For example, OID2, PID2, and AID2 correspond.

(1-2-1) Configuration of Optical Sensor Next, the configuration and detection operation of the optical sensor 101, the pressure sensor 102, and the acceleration sensor 103 of the wireless sheet 10 will be described individually.
First, the optical sensor 101 will be described with reference to FIG.
The optical sensor 101 is formed on a substrate 1 serving as a base, a dielectric thin film 2 that is formed on the substrate 1 and propagates a surface acoustic wave (SAW), and a dielectric thin film 2. An interdigital converter (IDT) converter 3 that converts an electrical signal into a surface acoustic wave or a surface acoustic wave into an electrical signal, and an external transceiver 21 connected to one of the converters 3 Are formed on the back surface of the substrate 1 and connected to the ground 5 through a through hole (not shown). The ground electrode 6 and the dielectric thin film 2 are formed on the dielectric thin film 2 to receive the surface acoustic wave and reflect it toward the conversion unit 3. The external reflection light 7 generates an electrical signal. A light receiving element 8 (e.g., a photoelectric cell) and the light receiving element; It is provided with, an impedance converter 9 to change the reflectivity of the surface acoustic wave by receiving the electric signals of the device 8 changes the impedance of the reflecting section 7.
The frequency of the surface acoustic wave in the optical sensor 101 is set by the shape of the conversion unit 3. In general, the frequency of the surface acoustic wave generated on the dielectric thin film 2 is in the range of 200 to 2500 MHz.

LiTaO ₃ is used as the material of the dielectric thin film 2 shown in FIG.
Moreover, the conversion part 3, the antenna 4, and the ground 5 are integrally formed by the conductive pattern. As a material of this conductive pattern, metals such as Ti, Cr, Cu, W, Ni, Ta, Ga, In, Al, Pb, Pt, Au, and Ag, or Ti—Al, Al—Cu, Ti—N, An alloy such as Ni—Cr is preferably laminated in a single layer or a multilayer structure of two or more layers, and Au, Ti, W, Al, and Cu are particularly preferable as the metal. Moreover, it is preferable that the film thickness of this metal layer shall be 1 nm or more and less than 10 micrometers.

  The dielectric thin film 2 preferably has an epitaxial or unidirectional orientation from the viewpoint of the electromechanical coupling coefficient / piezoelectric coefficient in the converter 3 or the dielectric loss of the antenna 4. Further, a thin film containing a group III-V semiconductor such as GaAS or carbon such as diamond may be formed on the dielectric thin film 2. Thereby, the surface velocity, the coupling coefficient, the piezoelectric constant, etc. of the surface acoustic wave can be improved.

Next, the operation of the optical sensor 101 will be described.
The optical sensor 101 exchanges radio signals with the transmitter 21A of the transceiver 21 and with the receiver 21B. The radio wave signal transmitted from the transmitter 21A is received by the antenna 4, and the converter 3 excites the dielectric thin film 2 by this signal to generate mechanical vibration. This mechanical vibration generates a surface acoustic wave on the surface of the dielectric thin film 2. The surface acoustic wave moves from the conversion unit 3 toward the reflection unit 7 and reaches the reflection unit 7.

On the other hand, in the light receiving element 8, since the impedance of the light receiving element 8 changes according to the received light quantity, the change in impedance is transmitted to the reflecting portion 7 through the impedance converter 9. The impedance change in the reflection unit 7 changes the reflectance when the surface acoustic wave propagated from the conversion unit 3 is reflected.
Then, the surface acoustic wave that has moved from the conversion unit 3 toward the reflection unit 7 is reflected by the reflection unit 7 having a reflectance set according to the amount of light received by the light receiving element 8 and returns to the conversion unit 3. The reflected surface acoustic wave is transmitted via the converter 3 and the antenna 4. The receiving unit 21B receives a radio signal from the optical sensor 101.

  As described above, the surface acoustic wave generated on the surface of the dielectric thin film 2 changes in amplitude, phase difference, frequency, etc. (attributes) depending on the reflectance of the reflecting portion 7 corresponding to the amount of light received by the light receiving element 8. Become. The receiving unit 21 </ b> B that has received the surface acoustic wave converts the radio wave signal into an electric signal and transmits it to the control unit 30. The control unit 30 can measure the amount of light received by the light receiving unit by analyzing the electrical signal.

(1-2-2) Configuration of Pressure Sensor Next, the pressure sensor 102 will be described with reference to FIG.
The pressure sensor 102 includes a substrate 1 made of Si as a base material, and a dielectric thin film 2 formed on the substrate 1 via an oxide film 1A and through which a surface acoustic wave (SAW) propagates. A pair of interdigital transducers (IDTs) 3A and 3B that are formed on the dielectric thin film 2 and convert the electrical signal into a surface acoustic wave or a surface acoustic wave into an electrical signal; Antennas 4A and 4B, which are connected to one of the pair of comb-shaped electrodes 3A and 3B and transmit / receive radio signals to / from an external transmitter / receiver, and the other of the pair of comb-shaped electrodes 3A and 3B , Ground electrodes 6 formed on the back surface of the substrate 1 and connected to the grounds 5A and 5B through through holes (not shown), and a pressure receiving portion 102A.
The pressure receiving portion 102A has a starting end fixed to the dielectric thin film 2, a tip slightly protruding from the pressure sensor 102, and the button portion 10A comes into contact therewith. The pressure applied to the button portion 10A from the outside reaches the dielectric thin film 2 via the pressure receiving portion 102A, and the dielectric thin film 2 is distorted to change the frequency of the surface acoustic wave.

  Further, a concave portion is formed on the back surface side of the substrate 1 by forming a taper surface of 54.75 degrees by anisotropic etching, and this bottom portion becomes a fragile portion and reacts to pressure from the outside. It becomes. In FIG. 5, the oxide film 1 </ b> A is depicted as being thick for the sake of convenience.

This pressure sensor 102 uses LiTaO ₃ as the material of the dielectric thin film 2. This LiTaO ₃ crystal is made of a material whose surface acoustic wave propagation velocity hardly changes with pressure change, and its temperature coefficient is about 18.0 × 10 ⁻⁶ / ° C. The temperature coefficient of the LiNbO ₃ crystal is as small as about 1/4, and the change rate of the surface acoustic wave is about 0.005% with respect to a temperature change of 10 ° C.

Since the dielectric thin film 2 is disposed on the diaphragm 1B through the oxide film 1A, when a pressure of, for example, 2 bar is applied to the diaphragm 1B from the outside, the diaphragm 1B is deformed, and the inter-electrodes of the comb electrodes 3A and 3B are deformed. In addition, the speed of the surface acoustic wave is changed and the frequency is changed by about 0.2% with respect to the center frequency f0 (about 300 MHz). Further, when the temperature change of the measurement object is significant, it can be corrected by using it together with the temperature sensor.
As described above, the pressure sensor 102 has been detected to change in frequency by about 0.2% with respect to the center frequency f0.

The frequency of the surface acoustic wave in the pressure sensor 102 is set in the shape of the comb electrodes 3A and 3B. The shape and size of the comb-shaped electrodes 3A and 3B generate mechanical vibration of the center frequency of the radio wave transmitted from the external transmitter, so that the intensity of the radio wave received by the receiver is shifted by the change in frequency. It will be.
In this pressure sensor 102, a concave portion is formed in the substrate 1 and the bottom is the diaphragm 1B. However, the diaphragm may be formed only by the oxide film 1A, and pressure applied from the outside is directly applied to the dielectric thin film 2. Or the shape which acts indirectly may be sufficient.

(1-2-3) Configuration of Acceleration Sensor Further, the acceleration sensor 103 will be described with reference to FIG.
The acceleration sensor 103 is different from the configuration of the pressure sensor 102 shown in FIG. 5 in that the pressure receiving portion 102A and the diaphragm 1B are not provided, and a base 103A that floats the other on one of the rectangular substrates 1. Is a point provided. Therefore, the same components as those of the pressure sensor 102 shown in FIG.

By providing the pedestal 41 on one side of the substrate 1, the acceleration sensor 103 has a cantilevered structure, and a force F (F = m × α (m: mass, α: acceleration) as shown in FIG. 6B. ) Is applied to the other side of the substrate 1, the substrate 1 bends in response to the acceleration, and the bending is measured by the dielectric thin film 2.
For use as an acceleration sensor, LiTaO ₃ is used as the material of the dielectric thin film 2 shown in FIG.

When acceleration (for example, 980 m / s ² ) is applied to the other side of the substrate 1, the substrate 1 bends in response to this acceleration, and this bend is transmitted to the dielectric thin film 2, and between the electrodes of the comb electrodes 3 A and 3 B. And the velocity of the surface acoustic wave changes to change the frequency by about 0.1% with respect to the center frequency. Further, when the temperature change of the measurement object is significant, it can be corrected by using it together with the temperature sensor. As described above, the acceleration sensor 103 has been detected to change in frequency by about 0.1% with respect to the center frequency f0.

(1-2-4) Sensor Identification ID Setting Method Next, another identification ID setting method will be described. Hereinafter, the sensors are collectively referred to as “wireless sensor 0”.
Specifically, in the above-described identification ID setting method, the wireless sensor corresponding to one frequency has been described. However, if the wireless sensor can individually correspond to a different frequency, the wireless sensor 0 is set for each different frequency. Can be identified.
As shown in FIG. 7, in the wireless sensor in which the comb-shaped electrodes 3A-1, 3B-1,... 3A-4, 3B-4 having different shapes are formed, a plurality of frequencies are obtained depending on the frequency of the radio wave transmitted from the outside. Corresponding surface acoustic waves are generated on the dielectric thin film 2.

For example, the surface acoustic wave frequency set by the comb electrodes 3A-1 and 3B-1 is f1, the surface acoustic wave frequency set by the comb electrodes 3A-2 and 3B-2 is f2, and the comb electrode 3A. The frequency of the surface acoustic wave set by −3 and 3B-3 is f3, and the frequency of the surface acoustic wave set by the comb electrodes 3A-4 and 3B-4 is f4.
In FIG. 7, the illustration of the ground and the ground electrode is omitted.

  Here, when a radio wave signal having a frequency f1 is transmitted from an external transmitter, in the comb-shaped electrode 3A-1, the electrode 3A-1 corresponding to the frequency f1 generates a mechanical vibration, and this mechanical vibration causes a dielectric. A surface acoustic wave is generated on the thin film 2. This surface acoustic wave is transmitted to the electrode 3B-1. The attribute of the surface acoustic wave transmitted to the electrode 3B-1 changes under the influence of pressure. On the other hand, since the other comb-shaped electrodes 3A-2, 3B-2 to 3A-4, 3B-4 are not tuned to the frequency f1, generation of surface acoustic waves and transmission of radio signals based thereon are performed. Absent. That is, these comb-shaped electrodes 3A-2, 3B-2 to 3A-4, 3B-4 are set to be tuned to frequencies f2, f3, f4, respectively. When transmitted to the sensor, a surface acoustic wave is transmitted through a path of comb-shaped electrodes 3A-2 → 3B-2, and a radio wave signal corresponding to the surface acoustic wave is output via the antenna 4B.

Similarly, when a radio signal having a frequency f3 is transmitted to the wireless sensor, a surface acoustic wave is transmitted through the path of the comb-shaped electrodes 3A-3 → 3B-3 and output via the antenna 4B. When the radio wave signal is transmitted to the wireless sensor, the surface acoustic wave is transmitted through the path of the comb-shaped electrodes 3A-4 → 3B-4 and output via the antenna 4B.
Therefore, if radio waves are transmitted to the wireless sensor in the order of the frequencies f1, f2, f3, and f4, response signals corresponding to these can be obtained. In this case, the change band of the signal output from the comb electrodes 3B-1, 3B-2, 3B-3, 3B-4 (output side) (the width of change due to pressure) should be set so as not to overlap. For example, even if the frequencies f1 to f4 are simultaneously output to the wireless sensor, the four signals output as response signals can be separated and analyzed.

  For example, in the four wireless sheets 10, sensors having different shapes of the comb-shaped electrodes 3A and 3B are individually provided. Specifically, the first wireless sheet 10 is a wireless sensor in which the comb-shaped electrodes 3A-1 and 3B-1 shown in FIG. 7 are formed. The second wireless sheet 10 has a comb-shaped electrode. The wireless sensor formed with 3A-2 and 3B-2, the third wireless sheet 10 has a wireless sensor with the comb electrodes 3A-3 and 3B-3, and the fourth wireless sheet 10 has A wireless sensor in which comb electrodes 3A-4 and 3B-4 are formed is provided. Thereby, the frequency of the surface acoustic wave generated in the dielectric thin film by each wireless sensor is different, and the wireless sheet can be specified by the frequencies f1 to f4 of the received sensor response signals. Can be planned.

Further, in the above example, a plurality of wireless sensors are identified by differentiating the frequencies of the wireless sensors and determining the frequencies. However, the wireless sensor identification method is not limited to this, and the wireless sensor identification method is not limited thereto. Any method can be used as long as the response signal of the sensor can be identified.
For example, the separation distance d (see FIG. 6A) between the comb-shaped electrodes 3A and 3B is made different for each sensor so that each sensor can be identified from the difference in time passing between the electrodes 3A and 3B. Also good.
Furthermore, the waveform transmitted to the wireless sensor is not limited to a rectangular wave, and any waveform such as a sine wave or a triangular wave may be used as long as measurement can be performed.

(1-3) Operation of Print Medium Management System Next, the operation of the print medium management system 100 according to the first embodiment will be described with reference to FIGS.
(1-3-1) Printing Process First, the printing process will be described with reference to the flowchart of FIG. In this process, the image of the paper image stored in the storage area 30E of the personal computer 20 is printed on the paper P. A wireless sheet 10 is attached to the paper P at a predetermined position in advance.

  When starting the printing process, it is assumed that the identification ID related to the wireless sheet 10 attached to the paper P accommodated in the paper accommodation unit of the printer 22 is stored in advance in the RAM 30D of the personal computer 30. That is, the personal computer 30 stores in advance the identification ID of each sensor of the wireless sheet 10 for each paper P to be printed. Specifically, the paper and the identification ID as shown in the right thick frame of the correspondence table TA in FIG. 2A are stored.

This printing process is executed when the user operates the operation unit 23 to input a print command.
First, the CPU 30B receives a print command input from the user via the operation unit 23 (step Sa1). At this time, the print command includes identification information of the electronic file together with format data of the image to be printed on the paper P.
The CPU 30B reads the electronic file identification information from the print command (step Sa2), and associates the identification information of the paper P stored in advance with the electronic file identification information (step Sa3). Then, the correspondence table TA shown in FIG. 2A is created and stored in the storage area 30E (step Sa4). Further, the CPU 30 </ b> B transfers a print command to the printer 22, and the printer 22 prints an image on the paper P.

(1-3-2) System Operation Next, the operation of the print medium management system 100 will be described based on the sequence chart shown in FIG.
In the present embodiment, each sensor is identified by the difference in the separation distance d between the comb-shaped electrodes 3A and 3B, so that each sensor is operated by a radio wave signal having the same frequency.
The CPU 30B of the personal computer 20 transmits a sensor inquiry signal having a predetermined frequency via the transceiver 21 (step Sb1).
In the wireless sheet 10, when each sensor receives a sensor inquiry signal (step Sb2), a surface acoustic wave is generated in the dielectric thin film 2 in each sensor. Each sensor transmits a sensor response signal corresponding to a change in physical operation of light, pressure, and acceleration (step Sb3).

  For example, the pressure sensor 102 transmits a sensor response signal in which the attribute (for example, frequency) of the sensor question signal does not change unless the button unit 10A is pressed, and when the button unit 10A is pressed, as described above. Like the operation of the pressure sensor 102, a sensor response signal having a frequency changed from the center frequency is transmitted.

The CPU 30B of the personal computer 20 receives the sensor response signal via the transceiver 21 (step Sb4), and performs an analysis process on the sensor response signal (step Sb5). In this analysis process, the identification ID of each sensor is acquired based on the calculated transmission time t (step Sb6), and the measurement result of each sensor is acquired from the attribute change of the sensor response signal (step Sb7).
And CPU30B writes identification ID and the measurement result of each sensor in sensor table TB as shown, for example in FIG.2 (b), and memorize | stores it in RAM30D.
Specifically, for each paper P1 to P5, identification information of electronic files: EID1 to EID5, measurement results by optical sensor 101: OP1 to OP5, measurement results by pressure sensor 102: PR1 to PR5, measurement results by acceleration sensor: AC1 to AC5 are written in the sensor table TB.

  Next, the CPU 30B refers to the sensor table TB stored in the RAM 30D, reads out the measurement results corresponding to the light, pressure, and acceleration applied to each wireless sheet 10, and performs processing according to the measurement results, that is, the sheet P. The arrangement state is detected (step Sb8).

  Here, the process according to a sensor signal is demonstrated, referring FIG. In this example, it is assumed that this process is performed on five sheets of paper P for convenience.

  First, the CPU 30B reads out the measurement results OP1 to OP5 of the optical sensor 101 from the sensor table TB (step Sc1), obtains the identification ID of the received optical sensor 101, and extracts the paper P from the identification ID (step Sc2). ). For example, as shown in FIG. 11, the top sheet P3 is extracted from the five sheets P1 to P5.

  Further, the CPU 30B reads out the measurement results AC1 to AC5 of the acceleration sensor 103 from the sensor table TB (step Sc3). Furthermore, the CPU 30B compares the measurement results AC1 to AC5, and detects that the sheets P1 to P5 are aligned if the measurement results AC1 to AC5 are approximately the same value (step Sc4).

Further, the CPU 30B reads out the measurement results PR1 to PR5 of the pressure sensor 102 from the sensor table TB (step Sc5).
When the sheets P are stacked in the thickness direction, the value of the measurement result (pressure, that is, gravity) increases as the sheet P is located below. Therefore, the overlapping order is known from this difference in values.
Therefore, the CPU 30B compares the measurement results PR1 to PR5 and arranges them in order of increasing pressure, and extracts the paper P from the identification ID of the pressure sensor 102 in this order (step Sc6). For example, as shown in FIG. 11, when the measurement result (value) becomes PR3 <PR5 <PR2 <PR4 <PR1, it is arranged from the top in the order of P3 → P5 → P2 → P4 → P1. To detect.
Then, the CPU 30B generates an instruction signal for making the arrangement state of the paper P obtained from the measurement results of the sensors 101 to 103 correspond to the display mode of the paper image, and temporarily stores it in the RAM 30D (step Sc7).

Returning again to FIG. 9, the CPU 30B reads the instruction signal from the RAM 30D and transmits it to the display unit 24 (step Sb9). Thereafter, it is determined whether or not there is a signal for ending this process (step Sb12). If not (step Sb12; NO), the process moves to step Sb1, and the processes after step Sb1 are repeated.
The display unit 24 receives the instruction signal transmitted from the CPU 30B (step Sb10), and changes the display mode of the sheet image transferred to the display unit 24 according to the arrangement state of the sheet P according to the instruction signal.

(1-4) Effects of Print Medium Management System As described above, in the print medium management system 100 according to the first embodiment, for example, the arrangement state of each sheet P on the desk and the display mode of the sheet image displayed on the display unit 24. Can be made to correspond.
Specifically, as shown in FIG. 11A, when the user arranges paper P3 → P5 → P2 → P4 → P1 in this order from the top, as shown in FIG. 11B, the paper image EP3 → EP5 → EP2 → EP4 → EP1 also displays the paper image on the display unit 24 in this order.

  In addition, when the user aligns each sheet P with “ton-ton” on the desk, the sheet image displayed on the display unit 24 can be similarly aligned. In addition, since it is considered that the user usually performs filing after aligning the sheets P, the personal computer 20 may perform processing such as storing in a folder when detecting that the sheets P are aligned. For example, paper image classification and file management can be easily performed.

  The wireless sheet 10 of the print medium management system 100 according to the present embodiment does not require a power source such as a battery, and transmits a sensor response signal for acquiring an identification ID using the received sensor question signal. Therefore, no work such as battery replacement or charging is required, and the usability can be greatly improved.

(1-4-1) Specific Example A specific example of the print medium management system 100 according to the first embodiment will be described.
FIG. 12 shows a case where the print medium management system 100 is used for a lecture or a presentation.
A projector 25 is connected to the personal computer 20, and a screen moving from the projector 25 to the display unit 24 is displayed on the screen 26. A transmitter / receiver 21 is arranged at the end of the podium 27 away from the personal computer 20, and a speaker X is present near the podium 27.
Usually, in a lecture or the like, a lecturer X explains while looking at materials, and a screen corresponding to the contents of the explanation is displayed in a full display state. Each time the lecturer X switches the explanation, the operator switches the screen by operating the operation unit 23 of the personal computer 20.
Therefore, when the system 100 according to the present embodiment is applied, when the material that the speaker X is viewing for the purpose of replacement is replaced, the screen on the screen 26 is automatically changed to a screen corresponding to the material that the speaker X is viewing. Switch to. This eliminates the need for an operator for switching the screen. Further, by switching to the screen corresponding to the operation of the speaker X, it is not necessary to communicate with the operator, and the lecture can be performed without giving a sense of incongruity to those who listen to the lecture.

In the case of this specific example, the material used for the explanation by the speaker X and the screen displayed on the screen do not need to coincide with each other, and a correspondence relationship may be set in advance.
The wireless sheet 10 may be provided with only the optical sensor 101.

(2) Second Embodiment Next, a second embodiment according to the present invention will be described with reference to FIGS. The feature of this embodiment is that the wireless sheet 10 is attached to each page of the book. In the present embodiment, the same components as those in the first embodiment described above are denoted by the same reference numerals, and the description thereof is omitted.

(2-1) Configuration of Print Medium Management System In the print medium management system 100 according to the present embodiment, the wireless sheet 11 is attached to each page P of the book B as shown in FIG. Only the optical sensor 101 is provided on the wireless sheet 11. In the correspondence table TC stored in the storage area 30E, as shown in FIG. 14, the identification ID of the electronic page / page and the optical sensor 101 is stored in association with each other.

(2-2) Operation of Print Medium Management System Next, the operation of the print medium management system 100 will be described with reference to the sequence chart of FIG.
The personal computer 20 transmits a sensor question signal having a predetermined frequency via the transceiver 21 (step Sd1).
In the wireless sheet 10, when the optical sensor 101 receives the sensor inquiry signal (step Sd2), a surface acoustic wave is generated in the dielectric thin film 2. The optical sensor 101 transmits a sensor response signal corresponding to a change in the physical operation of light (step Sd3).

  Here, the optical sensor 101 transmits a signal indicating that light is received only from the optical sensor 101 provided on the opened page, and indicates that no light is applied to the optical sensors 101 on other pages. A signal is transmitted.

The personal computer 20 receives the sensor response signal via the transceiver 21 (step Sd4), and performs an analysis process on the sensor response signal (step Sd5). In this analysis process, the identification ID of each optical sensor 101 is acquired based on the calculated transmission time t (step Sd6).
Then, the personal computer 20 specifies a page corresponding to the photosensor 101 that is illuminated from the identification ID, the measurement result of each photosensor 101, and the correspondence table TC (step Sd7).

  Next, the personal computer 20 determines whether or not the page obtained in the previous measurement has been switched (step Sd8). If the page has not been switched (step Sd8; NO), the personal computer 20 determines whether or not there is a signal to end this processing (step Sd9), and if not, (step Sd8; NO). It moves to step Sd1 and repeats the process after step Sd1.

  On the other hand, when the page is switched (step Sd8; YES), the time of the page that has been opened so far is stored in the RAM 30D in association with the page (step Sd10). Further, the timer T provided in the control unit 30 is started (step Sd11), and the process proceeds to step Sd9.

(2-3) Effects of the print medium management system Since the print medium management system 100 can store the time during which the page of the book B is opened, it is possible to grasp which page the reader is interested in. it can.
For example, when this print medium management system 100 is adopted in a library, it is possible to statistically grasp which page of which book the user is interested in.
Furthermore, if a borrowed book and a user are matched and grasped | ascertained for every user, a user's preference can also be known statistically.

(2-4) Modified Example In the second embodiment, the wireless sheet 11 is used to detect that the page of book B is opened. However, the present invention is not limited to this, and the target page is stored in advance in a personal computer. It may be specified by the operation unit 23 of 20 and an alarm or voice may be notified if the target page is opened while the reader flips the page. Specifically, the sequence chart of FIG. 16 is obtained.

  First, the personal computer 20 reads the target page of the book B input by the reader operating the operation unit 23 (step Se1). The personal computer 20 sets the identification ID of the optical sensor 101 corresponding to the target page from the correspondence table TC of FIG. 14 (step Se2) and stores it in the RAM 30D (step Se3).

  The personal computer 20 performs the processing of steps Sd1 to Sd7 described above, and specifies the page corresponding to the light sensor 101 that is illuminated.

  Next, the personal computer 20 determines whether or not the identification ID corresponding to the target page matches the identification number of the photosensor 101 that is illuminated (Step Se4). If they do not match (step Se4; NO), the personal computer 20 moves to step Sd1, and repeats the processing after step Sd1.

On the other hand, when the identification ID corresponding to the target page matches the identification number of the light sensor 101 that is illuminated (step Se4; YES), the personal computer 20 sounds an alarm of a notifying unit (not shown). (Step Se5), notifying that the target page has been opened.
Thereby, when a reader opens a target page, it can alert | report by sounding an alarm.

Also, the number of pages before and after the target page is set as the semi-target page, and when this semi-target page is opened, the alarm sound is changed and notified. In this way, even when the page turning speed is relatively fast, the target page can be reliably detected.
Further, the acceleration sensor 103 is provided on the wireless seat 11. In this case, since it is known how many times the target page is opened, this is notified before reaching the target page in consideration of the speed at which the reader flips the page. Thereby, the response delay of a sensor can be considered and a target page can be detected reliably.

(3) Third Embodiment Next, a third embodiment according to the present invention will be described with reference to FIGS. A feature of the present embodiment is that, by attaching two wireless sheets to one sheet P, the arrangement state of the sheet P and whether or not the sheet P is discarded are managed. In the present embodiment, the same components as those in the first embodiment described above are denoted by the same reference numerals, and the description thereof is omitted.

(3-1) Configuration of Print Medium Management System In the print medium management system 100 according to the present embodiment, the wireless sheets 12A and 12B are attached on the diagonal line of the paper P as shown in FIG. Only the acceleration sensor 103 is provided on the wireless sheets 12A and 12B. Two transceivers 21-1 and 21-2 are connected to the input / output unit 30 </ b> A of the personal computer 20.
In the correspondence table TD stored in the storage area 30E, as shown in FIG. 18, identification IDs of electronic pages / pages and two acceleration sensors are stored in association with each other.

(3-2) Operation of printing medium management system (arrangement state of paper P)
Next, the operation of the print medium management system 100 will be described with reference to the sequence chart of FIG. In this embodiment, the wireless sensor used for the wireless seat not only detects a physical quantity, but also uses the characteristic that the signal intensity or phase of the sensor response signal varies with the distance to the transceiver 21.
Since the operation from the transmission of the sensor inquiry signal to the acquisition of the sensor identification number is the same as that of the second embodiment described above, the same step numbers Steps Sd1 to Sd6 are described and the description thereof is omitted.

  The personal computer 20 measures the distances from the radio signal intensity corresponding to the acquired identification IDs of the acceleration sensors 103A and 103B to the transceivers 21-1 and 21-2, and detects the positions of the wireless sheets 12A and 12B. (Step Sf1).

  As an example of this processing, it is performed as shown in FIG. On the premise that the paper P is placed on a plane such as a desk, the transceivers 21-1 and 21-2 are installed at predetermined positions on the desk. At this time, the positions of the transceivers 21-1 and 21-2 are assumed to be a transceiver 21-1 (x01, y01) and a transceiver 21-2 (x02, y02) in a two-dimensional coordinate system. Further, the positions of the wireless sheets 12A and 12B are 12A (xA, yA) and 12B (xB, yB) in the coordinate system. Furthermore, the distance from the transceiver 21-1 to the wireless seat 12A is L1, the distance from the transceiver 21-1 to the wireless seat 12B is L2, the distance from the transceiver 21-2 to the wireless seat 12A is M1, and the transceiver 21 -2 to the wireless seat 12B is M2.

Here, as shown in FIG. 20, the intersection of the circle having the radius L1 with the transmitter / receiver 21-1 as the center and the circle having the radius M1 with the transmitter / receiver 21-2 as the center intersects the wireless seat 12A. The position of the wireless seat 12B is the intersection of the circle having the radius L2 with the transmitter / receiver 21-1 as the center and the circle having the radius M2 with the transmitter / receiver 21-2 as the center.
If this circle is expressed by a mathematical expression, the positions of the wireless sheets 12A and 12B with respect to the transceivers 21-1 and 21-2 are detected.
In the personal computer 20, the positions of the wireless sheets 12 </ b> A and 12 </ b> B are calculated in the coordinate system by performing the above processing.

Referring back to FIG. 19 again, the personal computer 20 calculates the inclination, the vertical and horizontal shifts with respect to the preset reference position from the positions of the wireless sheets 12A and 12B with respect to the transceivers 21-1 and 21-2. An instruction signal is generated (step Sf2), and this instruction signal is transmitted to the display unit 24 (step Sf3).
The display unit 24 receives this instruction signal (step Sf4), and changes the display of the paper image according to this instruction signal (step Sf5). On the other hand, the personal computer 20 returns until this processing is completed.

  For example, as shown in FIG. 20, even when the sheets P, P1, and P2 are arranged separately on the desk, the wireless sheet 12A for the transceivers 21-1 and 21-2 is provided for each of the sheets P, P1, and P2. , 12B are calculated in such a manner that the arrangement of the paper on the desk and the arrangement of the paper image on the display unit 24 coincide with each other. As a result, the layout of the paper image on the display unit 24 is reflected on the actual layout state of the paper P.

(3-3) Operation of Print Medium Management System (3-3-1) Discard Detection Due to Change in Spacing Size Next, the operation of the print medium management system 100 will be described with reference to the sequence chart of FIG. In this example, whether or not the paper P is torn is detected by cutting between the wireless sheets 12A and 12B and changing the distance therebetween.
Since the operation from the transmission of the sensor inquiry signal to the acquisition of the sensor identification number is the same as that of the second embodiment described above, the same step numbers Steps Sd1 to Sd6 are described and the description thereof is omitted. Further, since the wireless sheet position detection process is the same as that in step Sf1, the process is also omitted.

  The personal computer 20 calculates the separation distance from the detected positions of the wireless sheets 12A and 12B, and determines whether or not the separation distance has changed from the predetermined separation distance (step Sg1). Here, the separation dimension changes. If not (step Sg1; NO), the process proceeds to step Sg2, and unless the signal for ending the process is input, the process returns to step Sd1 to execute this process.

On the other hand, if there is a change in the separation size between the wireless sheets (step Sg1; YES), it is considered that the sheet P is broken and the wireless sheets 12A and 12B are separated, and the sheet image corresponding to the sheet is discarded. A discard signal instructing this is generated and transmitted to the display unit 24 (step Sg3).
The display unit 24 receives the discard signal (step Sg4), and erases the display of the displayed paper image according to the discard signal (step Sg5).

  In this example, the display of the paper image corresponding to the discarded paper on the display unit 24 is eliminated, but this data may be deleted from the storage area 30E in which the data of the electronic file is stored. . Specifically, the electronic file data indicated by the icon is moved to the trash box.

(3-3-2) Discard Detection Due to Acceleration Change Next, another example of the paper P discard detection will be described.
In this example, it is determined whether or not the acceleration value detected by each acceleration sensor 103 is discarded.

  In addition, the same step number is attached | subjected to the step which becomes the same operation | movement as the sequence chart of FIG. 21 mentioned above, and the description is abbreviate | omitted.

The personal computer 20 detects the acceleration for each sensor from the received radio wave signal (step Sh1). Next, the personal computer 20 compares the acceleration values of the respective speed sensors provided on the same sheet (step Sh2).
Here, if the acceleration values match (step Sh2; NO), it is determined that cutting or the like has not been performed on the paper P, and the process proceeds to step Sh3, and this processing is executed unless a signal for ending the processing is input. Therefore, the process returns to step Sd1.

On the other hand, when the acceleration values do not match (step Sh2; YES), it is considered that the sheet P is cut and the acceleration applied at the positions of the wireless sheets 12A and 12B is different. Then, the personal computer 20 determines that the paper is torn and discarded, generates a discard signal, and transmits it to the display unit 24 (step Sh3).
Thereafter, the display unit 24 receives the discard signal (step Sg4), and eliminates the display of the paper image displayed according to the discard signal (step Sg5).

  Thus, by attaching the wireless sheets 12A and 12B including the acceleration sensor 103 to one sheet P in a separated state, the discard of the sheet P can be detected when a different acceleration is detected. .

(4) Effects of the Embodiment As described above, in the embodiment, the wireless sheet 10 having a sensor that detects the state of the sheet P as a physical operation is attached to the substantial sheet P, and the radio wave from the wireless sheet 10 is attached. Based on the operation of the paper P detected by the signal, it is stored in the storage area 30E of the personal computer 20, and the display of the paper image corresponding to the paper P and the storage of the electronic file are managed.
Thereby, the display of the display unit 24 can be changed according to the arrangement state of the paper P, or the paper image data can be discarded. In addition, when the paper P is extracted and arranged, it is possible to manage data reflected in the movement of the actual paper P, such as extracting electronic files and collecting them in a folder.
