The control unit 11 of the display terminal 10 implements functions corresponding to the information acquisition unit 111, the image acquisition unit 112, the specifying unit 113, and the display control unit 114 by executing the stamp application 151.
The information acquisition unit 111 acquires the device identifier MID from the electronic stamp device 20 by performing Bluetooth communication using the first proximity communication unit 131.

  The image acquisition unit 112 performs network communication with the image server 30 through the network communication unit 133 and acquires stamp image data corresponding to the device identifier MID acquired by the information acquisition unit 111. When acquiring the stamp image data from the image server 30, the image acquisition unit 112 stores the stamp image data in the storage unit 15. At this time, the image acquisition unit 112 stores each of these stamp image data by a method capable of identifying the device identifier MID corresponding to each stamp image data stored in the storage unit 15.

  The specifying unit 113 specifies the device identifier MID of the electronic stamp device 20 that has moved within the distance range in which the second proximity communication unit 132 can communicate. Here, the specifying unit 113 indicates the electronic stamp device 20 that has moved the device identifier MID acquired by performing the NFC communication by the second proximity communication unit 132 within a distance range in which the second proximity communication unit 132 can communicate. As specified.

  The display control unit 114 reads stamp image data corresponding to the device identifier MID specified by the specifying unit 113 from the storage unit 15 and causes the display unit 14 to display the stamp image. At this time, the display control unit 114 determines the display position of the stamp image based on the operation data supplied from the touch screen unit 12. Here, the display control unit 114 sets the position where the touch operation is detected by the touch screen unit 12 as the display position of the stamp image.

  The control unit 31 of the image server 30 realizes a function corresponding to the stamp image management unit 311. The stamp image management unit 311 performs management related to the stamp image distributed to the display terminal 10. Here, the stamp image management unit 311 acquires stamp image data associated with the device identifier MID acquired by the image acquisition unit 112 of the display terminal 10 from the stamp image DB 331. The stamp image management unit 311 performs network communication with the network communication unit 32 and transmits stamp image data to the display terminal 10.

  FIG. 7 is a sequence diagram showing the flow of the stamp image display process in the image display system 1. FIG. 8 is a diagram for explaining a temporal change in the positional relationship between the display terminal 10 and the electronic stamp device 20. As shown in FIG. 8, the range in which the first proximity communication unit 131 can perform Bluetooth communication is referred to as “communication range R1”, and the range in which the second proximity communication unit 132 can perform NFC communication is referred to as “communication”. This is referred to as “possible range R2”. Hereinafter, the operation of the image display system 1 when a stamping operation using the electronic stamp device 20 of another user is about to be performed on the display terminal 10a will be described.

  The display terminal 10a reads the stamp application 151 from the storage unit 15 according to the user's operation, and executes the stamp application 151. Next, the display terminal 10a searches for Bluetooth compatible devices in the vicinity of the terminal itself (step S1). As shown in FIG. 8A, when the electronic stamp devices 20b and 20c are outside the communicable range R1, the display terminal 10a cannot search for the electronic stamp devices 20b and 20c in the process of step S1. However, as shown in FIG. 8B, when the electronic stamp devices 20b and 20c are moved into the communicable range R1, the display terminal 10a searches for the electronic stamp devices 20b and 20c in the process of step S1. To succeed.

The electronic stamp devices 20b and 20c within the communicable range R1 perform Bluetooth communication and transmit the device identifier MID stored in the storage unit 23 to the display terminal 10a (step S2). The electronic stamp device 20b transmits “M0002” as the device identifier MID. The electronic stamp device 20c transmits “M0003” as the device identifier MID.
When the display terminal 10a receives and acquires the device identifier MID, the display terminal 10a sends a request for transmitting a stamp image designating the acquired device identifier MID (hereinafter referred to as “image transmission request”) to the image server 30 through network communication. Transmit (step S3). Here, the display terminal 10a transmits an image transmission request designating “M0002” and “M0003” as the device identifier MID.

  When receiving the image transmission request, the image server 30 acquires, from the stamp image DB 331, stamp image data associated with the device identifier MID specified in the received image transmission request. Then, the image server 30 transmits the acquired stamp image data to the display terminal 10a through network communication (step S4). Here, the image server 30 acquires “img0002” and “img0003” as stamp image data from the stamp image DB 331, and transmits them to the display terminal 10a.

When receiving the stamp image data from the image server 30 and acquiring it, the display terminal 10a stores the acquired stamp image data in the storage unit 15 (step S5). Here, the display terminal 10a stores the stamp image data “img0002” and “img0003” in the storage unit 15 (see FIG. 8B). At this time, the display terminal 10a stores the stamp image data and the device identifier MID in the storage unit 15 in association with each other so that the device identifier MID corresponding to each stamp image data can be identified.
In the process of step S5, the display terminal 10a temporarily stores the stamp image data, for example, by creating a temporary file. For this reason, the display terminal 10a deletes the stamp image data temporarily stored in the storage unit 15 at a predetermined timing such as when the execution of the stamp application 151 ends or when a timeout occurs. The display terminal 10a stores the stamp image data in the storage unit 15 in the process of step S5, but does not display the stamp image represented by the stamp image data at this time.

Next, it is assumed that the user of the electronic stamp device 20b tries to perform a stamping operation on the display terminal 10a using the electronic stamp device 20b. In this case, prior to the stamping operation, the positional relationship between the electronic stamp device 20b and the display terminal 10a is as shown in FIG. That is, the electronic stamp device 20b is moved within the communicable range R2. On the other hand, the electronic stamp device 20c is outside the communicable range R2.
When moved to the communicable range R2, the electronic stamp device 20b transmits the device identifier MID stored in the storage unit 23 to the display terminal 10a by NFC communication (step S6). The device identifier MID is the same as that transmitted in the process of step S2, and is “M0002” here. On the other hand, since the electronic stamp device 20c is outside the communicable range R2, it does not transmit the device identifier MID.

  When the display terminal 10a receives and acquires the device identifier MID transmitted in the process of step S6, the display terminal 10a specifies the received device identifier MID as indicating the electronic stamp device 20 that has moved within the communicable range R2. Then, the display terminal 10a reads stamp image data corresponding to the specified device identifier MID (step S7). Here, the display terminal 10a reads “img0002” as stamp image data corresponding to the device identifier MID “M0002”. This read destination is, for example, the RAM of the control unit 11.

Then, when the touch operation on the display surface 141 is detected by the touch screen unit 12, the display terminal 10a displays a stamp image on the display unit 14 based on the stamp image data read out in the process of step S7 (step S8). . The position where the display terminal 10a detects the contact operation can be estimated as the position where the electronic stamp device 20b is brought into contact. For this reason, the display terminal 10a determines the position where the stamping operation is performed by the electronic stamp device 20b as the display position of the stamp image.
The display terminal 10a then reads the stamp image data read out in step S7, the device identifier MID corresponding to the stamp image data, and the position information indicating the display position of the stamp image (for example, indicating the position on the display surface 141). The possessed stamp information 152 is updated (step S9).

FIG. 9 is a diagram illustrating a display example of a stamp image displayed in the process of step S8. FIG. 9A is a diagram showing the electronic stamp book N in a state where no stamp image is displayed. As shown in FIG. 9A, the electronic stamp book N includes areas for stamping four stamps, namely, stamp areas T1 to T4.
For example, as shown in the upper part of FIG. 9B, it is assumed that the tip of the electronic stamp device 20b is brought into contact with the position P1 on the display surface 141 by the user's stamping operation. In this case, as shown in the lower part of FIG. 9B, the display terminal 10a displays the stamp image I1 in the stamp area T1. At this time, the display terminal 10a makes the center of the stamp image I1 coincide with the position P1. On the other hand, as shown in the upper part of FIG. 9C, it is assumed that the tip of the electronic stamp device 20b is brought into contact with the position P2 on the display surface 141 by the user's stamping operation. In this case, as shown in the lower part of FIG. 9C, the display terminal 10a displays the stamp image I1 in the stamp area T3. At this time, the display terminal 10a makes the center of the stamp image I1 coincide with the position P2. In this case, since the tip of the electronic stamp device 20b is brought into contact with a position near the end of the stamp area T3, a part of the stamp image I1 protrudes from the stamp area T3.
Even when the tip of the electronic stamp device 20b is brought into contact with another position, the display terminal 10a determines the display position of the stamp image based on the contact position.

  Thereafter, the display terminal 10a can display the electronic stamp book including the stamp image held by the terminal at any time by referring to the possessed stamp information 152. In the image display system 1, the processing described with reference to FIG. 7 is repeatedly executed while the display terminal 10 is executing the stamp application 151.

In the image display system 1 of the first embodiment described above, the display terminal 10 specifies the electronic stamp device 20 that may be subjected to the stamping operation by the electronic stamp device 20 within the communicable range R1, Stamp image data is acquired from the image server 30 in advance. Then, the display terminal 10 specifies the electronic stamp device 20 on which the actual stamping operation has been performed by the electronic stamp device 20 within the communicable range R2, and the stamp image data acquired in advance from the image server 30. A stamp image is displayed based on.
If the display terminal 10 acquires stamp image data from the image server 30 using the detection of the stamping operation as a trigger, the time lag between the stamping operation and the display of the stamp image is caused by a processing delay including a communication delay of network communication. May occur. However, in the image display system 1, since the display terminal 10 acquires the stamp image data from the image server 30 at the time when the stamping operation may be performed, this time lag can be reduced. Therefore, according to the image display system 1, when the stamp image is electronically displayed, it is possible to give the user a feeling of use that is similar to a case where an actual stamp using ink or vermilion is pressed.

  Furthermore, the display terminal 10 determines the display position of the stamp image at a position on the display surface 141 with which the electronic stamp device 20 is brought into contact. That is, when the electronic stamp device 20 is brought into contact with a position in the stamp area of the electronic stamp book, the display position of the stamp image also changes depending on where the contact position is in the stamp area. Therefore, according to the image display system 1, even when the position where the user actually performs the stamping operation becomes the display position of the stamp image, the user can have a feeling of use close to that when he / she presses the actual stamp. Can do.

(1) In the image display system 1 according to the first embodiment described above, the electronic stamp device 20 that may perform a stamping operation when the display terminal 10 and the electronic stamp device 20 perform Bluetooth communication and NFC communication. The electronic stamp device 20 on which the stamping operation was actually performed was specified. Instead, in the image display system 1 of this modification, the electronic stamp device 20 that may be subjected to the stamping operation only by Bluetooth communication and the electronic stamp device 20 that is actually subjected to the stamping operation are respectively provided. Identify.

  In this modification, the display terminal 10 detects the intensity of the radio wave emitted from the electronic stamp device 20 (that is, the first proximity communication unit 221) when the Bluetooth communication with the electronic stamp device 20 is performed. When the display terminal 10 acquires the device identifier MID from the electronic stamp device 20 whose radio wave intensity is equal to or higher than the first threshold, the display terminal 10 acquires stamp image data corresponding to the device identifier MID from the stamp image DB 331. And stored in the storage unit 15. When the display terminal 10 acquires the device identifier MID from the electronic stamp device 20 whose radio field intensity is less than the second threshold value which is smaller than the first threshold value, the display terminal 10 stores stamp image data corresponding to the device identifier MID in the storage unit 15. To display a stamp image.

  As described above, when the display terminal 10 can estimate the distance to the electronic stamp device 20 from the strength of the radio wave used for the proximity communication with the electronic stamp device 20, the stamping operation is performed based on the strength of the radio wave. It is possible to identify the electronic stamp device 20 that may be detected and the electronic stamp device 20 on which the stamping operation has actually been performed. If the display terminal 10 can identify (estimate) the distance between the two from the intensity of the radio wave used for wireless communication with the electronic stamp device 20, in this modification, a communication method other than Bluetooth communication may be adopted. Good.

(2) In the image display system 1 of the first embodiment described above, the device identifier MID transmitted from the electronic stamp device 20 by Bluetooth communication in the process of step S2 and the electronic stamp device 20 from NFC communication in the process of step S6. The transmitted device identifier MID was the same. Instead, in the image display system 1, in the process of step S <b> 2, the electronic stamp apparatus 20 transmits the device identifier MID, while in the process of step S <b> 6, the electronic stamp apparatus 20 transmits to the second proximity communication unit 222. Alternatively, a uniquely assigned identifier may be transmitted. This identifier is, for example, a unique ID that is recorded on the IC chip of the second proximity communication unit 222 and cannot be rewritten (hereinafter referred to as “NFCID”).

  In this case, in the stamp image DB 331 of the image server 30, it is only necessary to register the MAC address, NFCID, and stamp image data of Bluetooth communication in association with each electronic stamp device 20. The operation of the image display system 1 will be described. In the process of step S4, the image server 30 uses the NFCID of the electronic stamp device 20 together with the stamp image data corresponding to the electronic stamp device 20 within the communicable range R1. Transmit to the terminal 10. In the process of step S5, the user terminal 10 stores the stamp image data received from the image server 30 in the storage unit 15 by a method capable of identifying the NFCID received together with the stamp image data. When the user terminal 10 receives the NFCID transmitted in step S6, the user terminal 10 reads the stamp image data corresponding to the received NFCID from the storage unit 15 and displays the stamp image. In this way, the display terminal 10 uses the NFCID that is different from the device identifier MID received from the electronic stamp device 20 within the communicable range R1, and uses the device of the electronic stamp device 20 within the communicable range R2. The identifier MID can be specified.

  The device identifier MID used in the first embodiment described above may be an identifier other than the MAC address as long as it is an identifier that uniquely identifies the electronic stamp device 20. For example, the device identifier MID may be a service-specific identifier (service ID) for displaying a stamp image in the image display system 1. Also, the above-described NFCID can be replaced with another identifier different from the device identifier MID. For example, a service ID dedicated to a service can be used.

The proximity communication unit 223 is an interface for performing wireless communication without going through the network 100. Here, like the first proximity communication unit 221 of the first embodiment described above, the proximity communication unit 223 is an interface for performing Bluetooth communication. is there. The stamping operation detection unit 24 detects a stamping operation performed by the user using the electronic stamp device 20.

The stamping operation detection unit 24 supplies data indicating the pressing force detected by the pressure sensor to the control unit 21.

Although the illustration of the hardware configuration of the display terminal 10 is omitted, the first embodiment described above is provided in that a proximity communication unit 134 (see FIG. 11) is provided instead of the first proximity communication unit 131 and the second proximity communication unit 132.

Here, like the first proximity communication unit 131 of the first embodiment described above, the proximity communication unit 134 is an interface for performing Bluetooth communication. is there.
The hardware configuration of the image server 30 is the same as that of the first embodiment described above.

FIG. 11 is a functional block diagram showing a functional configuration of the image display system 1. Hereinafter, a functional configuration different from the above-described first embodiment will be described.
The control unit 21 of the electronic stamp device 20 realizes functions corresponding to the first communication control unit 211 and the second communication control unit 212.
The first communication control unit 211 performs Bluetooth communication using the proximity communication unit 223 and transmits the device identifier MID to the display terminal 10. The second communication control unit 212 performs Bluetooth communication by the second proximity communication unit 222 and transmits the device identifier MID and the seal information to the display terminal 10. The stamp information is information indicating that a stamping operation has been performed by the electronic stamp device 20, in other words, contact information indicating that the electronic stamp device 20 has touched the display surface 141. The second communication control unit 212 determines that the stamping operation has been performed based on the pressing force detected by the stamping operation detection unit 24. For example, the second communication control unit 212 determines that the stamping operation has been performed when the pressing force is equal to or greater than a threshold value.

The control unit 11 of the display terminal 10 implements functions corresponding to the information acquisition unit 111, the image acquisition unit 112, the specifying unit 113, and the display control unit 114 by executing the stamp application 151.
The information acquisition unit 111 performs Bluetooth communication with the electronic stamp device 20 by the proximity communication unit 134 and acquires the device identifier MID transmitted by the first communication control unit 211.
The image acquisition unit 112 performs network communication with the image server 30 through the network communication unit 133 and acquires stamp image data corresponding to the device identifier MID acquired by the information acquisition unit 111.
When the proximity communication unit 134 performs Bluetooth communication with the electronic stamp device 20 and acquires the device identifier MID and the seal information transmitted by the second communication control unit 212, the specifying unit 113 displays the device identifier ID on the display surface. The electronic stamp device 20 in contact with 141 is identified as being shown.
When the specifying unit 113 acquires the device identifier MID and the seal information, the display control unit 114 displays a stamp image on the display unit 14 based on the stamp image data stored in the storage unit 15 corresponding to the device identifier MID. Is displayed.
The functional configuration of the image server 30 is the same as that of the first embodiment described above.

FIG. 12 is a sequence diagram showing the flow of the stamp image display process in the image display system 1. FIG. 13 is a diagram for explaining a temporal change in the positional relationship between the display terminal 10 and the electronic stamp device 20. Hereinafter, the operation of the image display system 1 when a stamping operation using the electronic stamp device 20 of another user is about to be performed on the display terminal 10a will be described.
First, the display terminal 10a searches for Bluetooth-compatible devices in the vicinity of the terminal (step S1). Here, as shown in FIG. 13A, consider a case where the electronic stamp device 20b is within the communicable range R in which the proximity communication unit 134 can communicate. In this case, the electronic stamp device 20b within the communicable range R transmits the device identifier MID stored in the storage unit 23 to the display terminal 10a by Bluetooth communication (step S2).
When the display terminal 10a receives and acquires the device identifier MID, the display terminal 10a transmits an image transmission request to the image server 30 based on the acquired device identifier MID (step S3). The image server 30 transmits the stamp image data acquired from the stamp image DB 331 according to the image transmission request to the display terminal 10a (step S4). When the display terminal 10a receives the stamp image data from the image server 30 and obtains it, the display terminal 10a stores the stamp image data in the storage unit 15 (step S5).

Thereafter, it is assumed that a stamping operation for bringing the electronic stamp device 20b into contact with the display surface 141 of the display terminal 10a is performed. In this case, the positional relationship between the electronic stamp device 20b and the display terminal 10a is in the state shown in FIG. That is, the tip of the electronic stamp device 20b is brought into contact with the display surface 141 of the display terminal 10a.
The electronic stamp device 20b detects the stamping operation when it is brought into contact with the display surface 141 of the display terminal 10a and the pressing force detected by the stamping operation detection unit 24 is equal to or greater than a threshold value (step S10). When detecting the stamping operation, the electronic stamp device 20b transmits the device identifier MID and the stamping information to the display terminal 10a by Bluetooth communication (step S11).

  When the display terminal 10a receives and acquires the device identifier MID and the stamp information transmitted in the process of step S11, the display terminal 10a reads stamp image data corresponding to the device identifier MID from the storage unit 15 (step S7). Then, the display terminal 10a displays a stamp image based on the read stamp image data (step S8). Then, the display terminal 10a updates the retained stamp information 152 (Step S9). The processes in steps S7 to S9 are the same as those in the first embodiment described above.

In the image display system 1 of the second embodiment described above, the display terminal 10 obtains in advance stamp image data of the electronic stamp device 20 that may be subjected to a stamping operation, and detects the stamping operation. The stamp image data is read from the storage unit 15 and the stamp image is displayed. Thereby, according to the image display system 1, it is possible to display a stamp image as soon as a stamping operation is detected, and to give the user a feeling of use that is similar to when an actual stamp is pressed.
In the image display system 1 according to the second embodiment, the display terminal 10 and the electronic stamp device 20 only need to support near field communication using at least one communication method.

<Modification of Second Embodiment>
In the second embodiment described above, the stamping operation detection unit 24 has a pressure sensor that detects the pressing force applied to the tip of the electronic stamp device 20, but the stamping operation detection unit 24 has a configuration other than this. Also good.
For example, the stamping operation detection unit 24 may include an acceleration sensor and supply data indicating the detected acceleration to the control unit 21. When the stamping operation is performed by the electronic stamp device 20, it is estimated that, for example, the acceleration in the direction including the vertical downward component of the electronic stamp device 20 is increased. That is, the temporal change in acceleration applied to the electronic stamp device 20 when the stamping operation is performed should show a characteristic temporal change during the stamping operation. Therefore, the electronic stamp device 20 performs the process of step S10 when the temporal change in the acceleration applied to the terminal matches the predetermined temporal change during the stamping operation based on the data indicating the acceleration. A stamp operation is detected, and the device identifier MID and the stamp information are transmitted to the display terminal 10 in the process of step S11. At this time, it is desirable that the electronic stamp device 20 transmits the stamp information on the condition that the device identifier MID is transmitted in the process of step S2.
Further, the stamping operation detection unit 24 may detect that a predetermined operator (operation button) is operated by the user as a stamping operation. If the user is determined to operate the operator when performing the stamping operation by the electronic stamp device 20, the electronic stamp device 20 may detect the stamping operation when the operator is operated. .
As described above, the stamping operation detection unit 24 provided for the electronic stamp device 20 to detect the stamping operation can be variously modified.

The access point 40 transmits the area identifier by wireless communication every predetermined period within the communication area R3 formed by the own device. Here, when the electronic stamp device 20b and the display terminal 10a are within the communication area R3 of the access point 40, as shown in FIG. 19, the access point 40 has an area for the electronic stamp device 20b and the display terminal 10a. An identifier is transmitted (steps S12 and S13). The electronic stamp device 20b transmits the acquired area identifier and device identifier MID to the image server 30 by wireless communication via the access point 40 (step S14). The image server 30 associates the area identifier acquired from the electronic stamp device 20b with the device identifier MID, and writes it in a management table (not shown) stored in the storage unit 33. Based on this management table, the image server 30 identifies in which communication area each electronic stamp device 20 is currently located.

Then, the image server 30 generates combined stamp image data obtained by combining the stamp image data acquired from the stamp image DB 331 and the second stamp image DB 332, and transmits the combined stamp image data together with the device identifier in the process of step S16.
Thereafter, the stamp image is displayed by executing the processes of steps S5 to S9 in the image display system 1.

FIG. 21 is a diagram showing a display example of the electronic stamp book N when a stamping operation using the electronic stamp device 20b is performed in the communication area R3 of the access point 40.

[Fourth Embodiment]
The image display system 1 according to the first to third embodiments described above has a configuration in which the display terminal 10 adds and displays a stamp image each time a stamping operation is performed by the electronic stamp device 20. For example, when the present invention is used like a stamp card used in a store, it may be desired to limit the number of times stamp images are allowed to be stamped according to the purchase amount (settlement amount) of the user's shopping. That is, it may be desirable that the display terminal 10 does not additionally display the stamp image even if the stamping operation is performed exceeding the limit number.
Hereinafter, the case where the electronic stamp device 20 that is actually subjected to the stamping operation is detected by the method of the second embodiment will be described as an example. In the following description, the same components and processing steps as those of the image display system 1 of the second embodiment described above are denoted by the same reference numerals, and description thereof is omitted.

  FIG. 22 is a diagram showing the overall configuration of the image display system 1 according to the fourth embodiment of the present invention. As shown in FIG. 22, the image display system 1 includes a display terminal 10, an electronic stamp device 20, an image server 30, and a store terminal 50. The electronic stamp device 20 is a stamp device used in a store, and has the same configuration as that of the second embodiment described above.

A computer device provided. Here, the store terminal 50 communicates with the electronic stamp device 20 by NFC communication. For this reason, it is assumed that the proximity communication unit 223 of the electronic stamp device 20 is an interface for performing NFC communication. When the store terminal 50 calculates the price of the product and completes the settlement, the store terminal 50 indicates the number-of-times information indicating the number of times that the stamp image can be stamped according to the settlement amount (hereinafter referred to as “the number of times the stamp can be stamped”). To the electronic stamp device 20. Typically, the higher the settlement amount, the greater the number of possible stamps. This number information can be said to be information (upper limit information) indicating the upper limit value of the additional display number of stamp images.

FIG. 23 is a sequence diagram showing the flow of the stamp image display process in the image display system 1. In FIG. 23, the description about the image server 30 and the description of steps S1 to S6 are omitted, but the same processing as in the second embodiment described above is executed. FIG. 24 is a diagram showing a display example of the electronic stamp book N.
When the payment processing is completed, the shop terminal 50 transmits the number-of-times information corresponding to the payment amount to the electronic stamp device 20 by NFC communication (step S18). When receiving the number information, the electronic stamp device 20 stores it in the RAM of the control unit 21 or the storage unit 23. Here, it is assumed that the frequency information is information indicating “twice” as the possible number of times of stamping.

  Thereafter, as shown in the upper part of FIG. 24A, when the electronic stamp device 20 detects a stamping operation to the stamping area T1 (step S10a), the device identifier MID and the stamping information are transmitted to the display terminal 10 ( Step S11a). The electronic stamp device 20 performs the process of step S11a because the number of transmissions of the device identifier MID and the stamp information is still less than or equal to the possible number of stamps indicated by the number of times information. When the display terminal 10 receives and acquires the device identifier MID and the stamp information transmitted in the process of step S11a, the display terminal 10 reads the stamp image data corresponding to the device identifier MID from the storage unit 15 and displays the stamp image. And the like are performed (steps S7a to S9a). The process of each process step of step S7a-S9a may be the same as each process of step S7-S9. Thus, the first stamp image is displayed, and the stamp image I2 is displayed in the stamp area T1 of the electronic stamp book N as shown in the lower part of FIG.

  Next, as shown in the upper part of FIG. 24B, when the electronic stamp device 20 detects a stamping operation to the stamping area T2 (step S10b), the device identifier MID, the stamping information, and the display terminal are transmitted to 10. (Step S11b). The electronic stamp device 20 performs the process of step S11b because the number of transmissions of the device identifier MID and the stamp information is still less than or equal to the number of stampable times indicated by the number of times information. When the display terminal 10 receives and acquires the device identifier MID and the stamp information transmitted in the process of step S11b, the display terminal 10 reads the stamp image data corresponding to the device identifier MID from the storage unit 15 and displays the stamp image. The process etc. which perform are performed (step S7b-S9b). The process of each process step of step S7b-S9b may be the same as each process of step S7a-S9a. As a result, the second stamp image is displayed, and the stamp image I2 is displayed in the stamp area T2 of the electronic stamp book N as shown in the lower part of FIG.
