<Embodiment 1>
A first embodiment of the present invention will be described with reference to FIGS.
According to the present invention, when performing facsimile communication, the transmission side independently issues a transmission certificate that proves the fact that the transmission action has been performed. In the present embodiment, as one form of facsimile communication, a store such as a convenience store for business uses a facsimile apparatus installed in the store (hereinafter referred to as “Fax apparatus 50”) to provide the public with a facsimile communication service. An example is provided that provides

  FIG. 1 is a block diagram showing a configuration of a communication system S constructed in a store, and reference numeral 20 in the figure denotes a server device. A controller 30 is communicably connected to the server device 20 via a LAN (local area network). A fax device 50 and a card reader 40 are connected to the controller 30 via signal lines such as USB. Reference numeral 60 denotes a destination fax machine. The fax device 50 and the controller 30 correspond to an example of a transmission terminal of the present invention, and the fax device 60 corresponds to an example of a reception terminal of the present invention.

  The fax machine 50 is a multifunction machine having a scanner function and a printer function in addition to a facsimile function, and includes a communication unit 55 responsible for the facsimile function, a reading unit (corresponding to the reading means of the present invention) 53 responsible for the scanner function, and a printer function. The printing unit (an example of the proof issuing unit of the present invention) 51 serving, the mode switching unit 57, the memory 59, and the like. The mode switching unit 57 selects either the normal mode or the transmission certificate issuance mode when executing facsimile communication.

  Note that the normal mode is a mode in which no transmission certificate is issued. When the mode is selected, normal facsimile communication is performed, and hence the description of the normal mode will be omitted.

  The server device 20 stores and manages various types of software, and is configured to supply software to the controller 30.

  The controller 30 is responsible for at least a part of the function as the certificate issuing means of the present invention. The controller 30 controls operation permission / prohibition of the operation of the fax device 50, and when the communication processing is started, Based on the notified status (processing state), it is determined whether or not the transmission process is confirmed. When the transmission process is confirmed, the fax apparatus 50 is instructed to issue a transmission certificate (see FIG. 2).

FIG. 3 is a sequence diagram showing communication processing of the communication system S.
The communication system S employs credit settlement, and a client using the service first needs to perform a procedure for settlement at a store. That is, when a credit card is slotted into the card reader 40, information (card number or the like) written on the IC chip of the card is read and sent to the controller 30. Then, the controller 30 performs processing for transferring the sent information to the server device 20. The server device 20 performs processing for transferring the received information such as a card number to a card company and making an inquiry.

  When the credit card inquiry by the server device 20 is completed, the controller 30 gives an operation permission to the fax device 50 (step 10 in FIG. 2). Only then is the fax device 50 ready for use. In addition, after giving the operation permission to the fax apparatus 50, the controller 30 waits for a status notification from the fax apparatus 50 (step 20 in FIG. 2).

  When the fax apparatus 50 is ready for use, the client selects a mode (in this case, the transmission certificate issuance mode is selected), and thereafter, a series of input operations for transmitting a document is performed by the client. It is done by. That is, a manuscript (here, all three pages) is set on the fax apparatus 50, a transmission destination dial number is key-inputted, and then a transmission instruction is performed by operating a start key (not shown). .

  As a result, the selected mode, dial information, and the like are received by the fax apparatus 50, and then the process of reading the document is executed by the fax apparatus 50. In the present embodiment, an example of transmitting a document using so-called memory transmission is illustrated, and all pages of the document are temporarily stored in the memory 59 in the fax apparatus 50.

  When the reading of the image data for all pages of the document is completed, the telephone line with the transmission destination is closed, and then negotiation with the transmission destination Fax device 60 (when the two devices establish communication). The communication setting is determined while exchanging information such as the communication speed).

  Then, the sender's fax device 50 notifies the controller 30 of the status in the course of executing the above-described processing. That is, as shown in FIG. 3, when a transmission destination dial number is inputted, dial information is notified, when reading of a document is started, that fact is notified, and then when reading of the document is completed, This is notified. In addition, the fax device 50 notifies the controller 30 about the closing of the line, the start of the negotiation, and the completion of the negotiation each time.

Then, every time there is a status notification, the controller 30 performs a process of determining whether or not the transmission process is confirmed (step 30 in FIG. 2). More specifically, the controller 30 determines that the transmission process has been confirmed when both of the following two statuses are notified from the fax machine 50.
a. Completion of document reading b. Completion of negotiation

  As a result, the controller 30 determines that the transmission process has been confirmed at the timing (3) in FIG. When the transmission process is confirmed, the controller 30 performs a process of generating an ID number (an example of a unique identification number of the present invention) based on the store number, the date on which the service is performed, and the like (step 40 in FIG. 2). When the generation of the ID number is completed, the controller 30 notifies the fax device 50 to instruct to issue a transmission certificate (step 50 in FIG. 2).

  It should be noted that “the image data to be transmitted is specified (reading of the original document is completed) and communication with the receiving terminal (fax device 60) as the transmission destination is established according to the present invention by the processing of steps 30 and 50 by the controller 30 described above. “Issuing a transmission certificate on the condition that (negotiation is completed)” is realized.

  On the other hand, in the fax machine 50 that has received a transmission certification instruction from the controller 30, processing for issuing a transmission certification is performed. Specifically, at least a part of the image data of the original is read from the memory 59, and then, for example, specific image data such as a certification stamp is synthesized with the data, and this is printed on a sheet by the printing unit 51. Print. Note that this is an example of information indicating that specific image data such as a certification stamp is a transmission certification of the present invention.

  In this embodiment, as shown in FIG. 4, a transmission certificate is issued for each page individually. In addition, the character string “XXX” shown in the upper right part of the proof stamp in the figure is an ID number generated by the controller 30. In addition, the present embodiment is configured such that a transmission report in which items of transmission (transmission time, transmission source, and transmission destination are listed) is printed out together with the transmission proof of each page.

  As described above, since the transmission report and the transmission proof are issued on the condition that the transmission process is confirmed, the client can transmit the transmission report without waiting for the completion of the transmission process for the destination Fax device 60. Alternatively, a transmission certificate can be received, and the store can be left at this timing.

  Subsequent to the above-described processing for issuing a transmission certificate, processing for transmitting a document from the fax device 50 serving as a transmission source to the fax device 60 serving as a transmission destination is performed. That is, first, image data is read from the memory 59 for the first page of the document, and this is transmitted to the fax apparatus 60 as a transmission destination via a telephone line. When the transmission of the first page of the original is completed, the image data is read from the memory 59 for the second page of the original, and this is transmitted to the fax apparatus 60 as the transmission destination via the telephone line. Then, in the same manner, the image data is transmitted for the third page of the document, and the line is opened when the transmission of all the image data is completed.

  Further, even during the transmission process described above, each status is notified from the fax machine 50 to the controller 30. That is, every time image data is transmitted for each page, a notification to that effect is transmitted to the controller 30, and when the line is released, a notification to that effect is transmitted to the controller 30.

On the other hand, when the controller 30 performs the process of instructing the printing of the transmission certificate in step 50, the controller 30 again waits for the status notification (step 60). When the status notification is received, the line is released. A process of determining whether or not has been performed is performed (step 70).
Note that the process in which the controller 30 issues a print instruction to the fax machine 50 in step 50 realizes “the certificate issuing unit issues the transmission certificate by printing on a recording medium” in the present invention.

  When a notification indicating the completion of line opening is received, a Yes determination is made at Step 70 and the routine proceeds to Step 80. In step 80, the controller 30 performs processing for notifying the fax device 50 of an operation prohibition command. As a result, the fax apparatus 50 is in the original use-prohibited state.

  As described above, since the transmission certificate is issued when the facsimile communication service is provided, it is possible to easily prove the fact that the transmission action was performed after the fact, and the added value of the communication system S is increased. In addition, if a predetermined condition is satisfied, a transmission certificate is issued even before the image data is received by the destination fax device 60. With such a configuration, since there is no need to wait for a notification regarding reception completion from the receiving terminal as in the prior art, a transmission certificate can be issued at an early stage, and convenience is enhanced.

  In addition, a transmission certificate is issued on condition that reading of image data to be transmitted is completed and negotiation with a transmission destination is completed. If such a condition is satisfied, it is unlikely that the facsimile transmission will end abnormally, which is suitable as a timing for instructing the issuance of a transmission certificate. In other words, after the negotiation is completed, a transmission error due to a negotiation failure does not occur. If the image data to be transmitted has been read, even if an error occurs for some reason during the transmission, the image data to be transmitted has already been read. Is possible.

  In addition, in the present embodiment, although it is necessary to complete the negotiation, the transmission source fax device 50 issues a transmission certificate regardless of the reception status of the transmission destination fax device 60. There is no need to provide any dedicated device for the fax device 60, and a general-purpose device can be used as the destination fax device 60.

  In addition, according to the present embodiment, the transmission certificate includes at least a part of image data for each document to be transmitted. With such a configuration, it is possible to grasp whether or not all the documents have been transmitted by referring to the transmission certificate. For example, when double feeding or the like has occurred, image data is not included in the transmission certificate for the overlapping originals. Therefore, it can be understood that a document whose image data is not included in the transmission certificate is not transmitted.

<Embodiment 2>
In the first embodiment, whether or not the transmission process is confirmed is determined based on the following two conditions.
a. Completion of document reading b. Completion of negotiation

On the other hand, the second embodiment is common in that two conditions are imposed on the determination, but the contents of the conditions are different from those of the first embodiment and are set as follows.
a. Start key reception (corresponding to the instruction of transmission of the present invention)
b. Completion of document reading (corresponding to identification of image data of the present invention)

  As a result, it is determined that the transmission process is confirmed at the timing (1) in FIG. Therefore, it is possible to issue a transmission certificate earlier than in the first embodiment. Other configurations are the same as those in the first embodiment.

<Embodiment 3>
In the first embodiment, whether or not the transmission process has been determined is determined based on the following two conditions.
a. Completion of document reading b. Completion of negotiation

On the other hand, in the third embodiment, the contents of the determination conditions are set different from those in the first embodiment as follows.
a. At least part of the image data has been sent

  As a result, it is determined that the transmission process is confirmed at the timing (4) in FIG. Accordingly, the transmission certificate issuance timing is delayed as compared with the case of the first embodiment. However, when the transmission certificate is issued, transmission of some image data has already been completed. It is very unlikely that it will end, increasing the reliability of the transmission certificate.

<Embodiment 4>
Next, a fourth embodiment of the present invention will be described with reference to FIGS.
In the fourth embodiment, the status is notified from the controller 30 to the server device 20 when the transmission process is finalized and the issuance of the transmission certificate is instructed and when the transmission process is completed (see FIG. 5). ). And based on these both notifications, the server apparatus 20 decided to output according to a transmission condition.
In FIG. 5, the step (timing) according to the first embodiment is applied as the step for instructing the issuance of the transmission certificate. However, the step (timing) according to the second or third embodiment is applied as this step. May be.

  Specifically, referring to the flowchart shown in FIG. 6, when the facsimile communication process is started, the server device 20 enters a standby state waiting for a status notification (step 100). Then, when there is a status notification from the controller 30, the process proceeds to step 110 to perform a process for determining the notified status.

  If the status notified from the controller 30 indicates the issuance of a transmission certificate, a Yes determination is made at step 110 and the routine proceeds to step 120. In step 120, processing for accepting the status is performed. Specifically, together with the ID number, a transmission certificate issuance history is stored by the server device 20.

  When the process of step 120 is completed, the process proceeds to step 130 and enters a standby state waiting for status notification. Then, when there is a status notification from the controller 30, the process proceeds to step 140, and processing for determining the notified status is performed. In this step 140, Yes is determined when the notified status indicates that the transmission process is completed, and No is determined when the notified status is other than that indicating that the transmission process is completed.

  The process in the case where the determination is No will be described first. Thereafter, the process proceeds to step 150, and a determination is made as to whether or not the predetermined time To has elapsed. If the predetermined time To has not elapsed, the determination at step 150 is No, and the process proceeds to step 130 again.

  As a result, the server apparatus 20 determines whether the predetermined time To has elapsed and the determination in step 150 is Yes, or until the notification indicating the completion of the transmission process is given and the determination in step 140 is Yes. The determination No) and step 150 (determination No) are repeated. As shown in FIG. 5, the fixed time To is set to a time sufficiently longer than the time required for the fax device 60 on the other side to complete the transmission of the document after notification of the transmission certificate is issued. ing.

  From the above, normally, before the fixed time To expires, the controller 30 notifies the server device 20 of the completion of the transmission process, and a Yes determination is made in step 140. Then, if a Yes determination is made at step 140, the process proceeds to step 170, and processing for accepting the status is performed. Specifically, the server apparatus 20 stores the transmission processing completion history together with the ID number. Then, when the process of step 170 is completed, the process proceeds to step 180, and an output corresponding to the acceptance process is performed. Specifically, the server device 20 notifies a client registered in advance (for example, a client registered mail transmission destination (mail address)) that the transmission is completed.

On the other hand, if a transmission error occurs for some reason, the controller 30 does not notify the server device 20 that the transmission process has been completed, and the time is up after a certain time To has elapsed. As a result, a Yes determination is made at step 150, and then the process proceeds to step 160. In step 160, a transmission error is output. In other words, the server device 20 notifies a pre-registered client contact information (for example, a pre-registered client mail transmission destination (mail address)) that a transmission error has occurred.
It should be noted that the processing of steps 140 to 160 executed by the server device is performed when the completion notification of the transmission process is not transmitted even after a predetermined time has elapsed after receiving the transmission certificate issuance notification. The function fulfilled by the “output means for outputting a transmission error” is realized.

  As described above, in the fourth embodiment, when a transmission completion notification is not received even after a predetermined time To has elapsed after the transmission certificate is issued, a notification that a transmission error has occurred is performed. did. With such a configuration, even if the transmission finally ends up being unsuccessful, it is possible to notify the client of this, so that the reliability of the system is improved.

<Embodiment 5 (corresponding to claim 6)>
Next, Embodiment 5 of the present invention will be described with reference to FIG.
In the fifth embodiment, a function of notifying the transmission destination that the image data transmitted to the first embodiment is a transmission certificate is added.

  More specifically, as shown in FIG. 7, the fax apparatus 50 is provided with a content certification notification unit (corresponding to a transmission certification notification unit of the present invention) 81. The content certification notifying unit 81 performs processing for superimposing specific image data (a character string of content certification Fax in the example of FIG. 7) on the image data transmitted to the counterpart Fax device 60. As a result of the weighted image data being transmitted through the communication unit 55, the destination fax device 60 receives the image data in which the character string of the content proof fax is embedded.

  With such a configuration, it is possible to make a user who receives a document recognize that the transmitted document is an important subject of transmission certification.

  In addition, as shown in FIG. 7, a character string “xxxx” is written in the upper right portion of the character string “content proof Fax”, which is generated by the controller 30 when the transmission certificate is issued. ID number.

  In this way, it is possible to improve the reliability of the content certification by causing the ID number to be written in addition to the display showing the content certification on the transmitted document. For example, if the transmitted document does not have an ID number or if it has a different number, it can be determined that the document has been forged.

<Embodiment 6 (corresponding to claim 11)>
In the first embodiment, the transmission certificate is printed on a recording medium and printed out. In the sixth embodiment, the transmission certificate is stored as electronic data. As shown in FIG. 8, a dedicated data storage unit (corresponding to storage means of the present invention) 21 is provided in the server device 20 in order to store electronic data of transmission certifications collectively.

  The specific processing will be briefly described. As shown in FIG. 9, the controller 30 determines the transmission processing (in the first to third embodiments, different examples are shown as the transmission processing determination timing. The ID number is generated). Thereafter, the fax device 50 is instructed to transfer the transmission certificate. Then, the fax device 50 that has received the transfer instruction generates image data of a transmission certificate, and the controller 30 transfers the image data to the server device 20.

  The transferred image data of the transmission certificate is stored in the data storage unit 21 of the server device 20. On the other hand, the fax device 50 issues only a transmission report instead of issuing a transmission certificate. With such a configuration, when the communication service is used, the client can receive only the transmission report and refer to the server device 20 later to refer to the transmission certificate. Thus, if the transmission certificate is stored as electronic data, it contributes to paperlessness, and the management man-hours can be reduced by collectively managing the transmission certificate.

<Other embodiments>
The present invention is not limited to the embodiments described with reference to the above description and drawings. For example, the following embodiments are also included in the technical scope of the present invention, and further, within the scope not departing from the gist of the invention other than the following. Various modifications can be made.

  (1) In the first to sixth embodiments, the controller 30 is provided separately from the transmission source Fax device 50. However, it is only necessary to provide a function of determining transmission confirmation and issuing a transmission certificate based on the determination. The function of the controller 30 may be built in the fax machine 50 of the transmission source.

  (2) In each of the first to sixth embodiments, memory reading in which the read original is temporarily stored in the memory, sequentially read out, and transmitted to the other party is exemplified. However, the transmission method is limited to this. The present invention is not limited to this, but can also be applied to an apparatus that transmits image data of a document to the other party each time the document is read.

  (3) In the first to fifth embodiments, the transmission certificate is printed on a recording medium and printed out after the transmission process is confirmed. In addition, the transmission is completed after the transmission process is completed. A certificate may be issued (see FIG. 10).

  (4) In the first to fifth embodiments, a transmission certificate is issued for each page. Specifically, when the document is all three pages, three transmission certificates are issued (see FIG. 4). The transmission certificate only needs to include at least a part of the image data of each document. For example, as shown in FIG. 11, the transmission certificate may be integrated on a single sheet.

  (5) In the first embodiment, the completion of the negotiation is cited as one of the conditions for determining that the transmission process is final. However, the condition may be immediately after the start of the negotiation. Because, after negotiation is started, if negotiation is completed for items that are important for communication, there is a high possibility that transmission can be performed even if negotiation is not completed. For example, the transmission process can be determined at the timing (2) in FIG.
