  By the way, it is convenient if the user of each terminal device can confirm the history of message exchange with other users. However, if the history of the partner who sent and received the message many times in the past and the history of the partner who has not yet fully exchanged are presented to the user, only the history of the partner who has interacted in the past is selectively displayed. There is a problem that it is difficult to make a confirmation and to selectively confirm only the history of a partner who has not been exchanged. Especially in the configuration that can receive a message from an unspecified partner such as SNS (Social Networking Service), since the history of the partner who has interacted in the past can be buried in the history of a large number of partners who have not interacted, The problem that selective confirmation of the history is difficult becomes serious. In view of the above circumstances, an object of the present invention is to facilitate confirmation of a history of message exchange with each other user.

<First Embodiment>
FIG. 1 is a block diagram of a communication system 100 according to the first embodiment of the present invention. The communication system 100 according to the first embodiment includes a management device 12 and a plurality of terminal devices 14. Each terminal device 14 is a communication terminal such as a mobile phone or a smartphone, and communicates with the management device 12 via a communication network 16 (for example, a mobile communication network or the Internet).

  The communication system 100 according to the first embodiment is a message exchange system in which the terminal devices 14 exchange messages with each other. Specifically, a chat system in which messages exchanged between a plurality of terminal devices 14 are sequentially displayed on each terminal device 14 in time series will be exemplified as the communication system 100 below. The management device 12 is, for example, a server device (SNS server device) that provides SNS to users of each terminal device 14, and serves as a relay device that transfers a message transmitted from each terminal device 14 to a destination terminal device 14. Function. In the following description, attention is paid to one terminal device 14 used by an arbitrary user X, and users of other terminal devices 14 that exchange messages with the terminal device 14 of the user X (that is, users) , A user who exchanges messages with user X) is referred to as “other user”. In the following, it is assumed that two terminal devices 14 exchange messages with each other, but the present invention is similarly applied to a case where three or more terminal devices 14 exchange messages with each other (group chat). Can be done.

  FIG. 2 is a block diagram of each terminal device 14. As shown in FIG. 2, the terminal device 14 is realized by a computer system including a control device 20, a storage device 22, a communication device 24, a display device 26, and an input device 28. The control device 20 is an arithmetic processing device that comprehensively controls each element of the terminal device 14. The communication device 24 communicates with other terminal devices 14 via the communication network 16 and the management device 12. The communication between the terminal device 14 and the communication network 16 is typically wireless communication. However, for example, when a stationary personal computer or the like is used as the terminal device 14, the terminal device 14 and the communication network 16 Can also be wired.

  The display device 26 (for example, a liquid crystal display panel) displays various images under the control of the control device 20. The input device 28 is a device for the user X to input an instruction to the terminal device 14 and includes, for example, a plurality of operators operated by the user X. Note that a touch panel configured integrally with the display device 26 and a microphone for inputting an instruction to the terminal device 14 by voice may be employed as the input device 28.

  The user X of the terminal device 14 can arbitrarily specify a desired message or the destination terminal device 14 by appropriately operating the input device 28. For example, the management device 12 extracts a plurality of selection candidates from members registered in advance and presents them to the terminal device 14 of the user X. The selection candidate extraction method is arbitrary. For example, a configuration in which selection candidates are randomly extracted from a plurality of members, or a member corresponding to attribute information registered in advance for the user X (for example, age, gender, preference, etc.) (Member whose attribute information matches) is selected as a selection candidate. The user X can select a message transmission destination from a plurality of selection candidates presented by the management device 12 by appropriately operating the input device 28. Therefore, there is a possibility that messages are transmitted and received between users who have not exchanged in the past.

  The storage device 22 stores programs executed by the control device 20 and various data used by the control device 20. For example, the storage device 22 stores, for each partner user, a history (hereinafter referred to as “transmission / reception history”) H of transmitting or receiving a message with the terminal device 14 of the partner user.

  FIG. 3 is a schematic diagram of a transmission / reception history H of an arbitrary partner user Y stored in the storage device 22 of the terminal device 14 of the user X. As shown in FIG. 3, the transmission / reception history H includes a plurality of unit information U corresponding to each message transmitted / received between the terminal device 14 of the user X and the terminal device 14 of the partner user Y. The That is, one unit information U in the transmission / reception history H is transmitted once from the terminal device 14 of the user X to the terminal device 14 of the partner user Y or from the terminal device 14 of the partner user Y. This corresponds to one transmission of a message to the terminal device 14 of the user X (one reception of a message by the terminal device 14 of the user X). As shown in FIG. 3, each unit information U in the transmission / reception history H includes transmission side information QS, reception side information QR, time information QT, and a message M. The message M is a code string in which a plurality of codes such as characters and symbols are arranged.

  The transmission side information QS is user information of the user on the transmission side of the message M. The user information of each user includes identification information uniquely given to the user and display information for designating a code representing the user (for example, a character string such as a name or a nickname). The identification information is fixedly set for each user, and the display information is variably set according to an instruction from the user, for example. The transmission side information QS in the unit information U corresponding to the message M transmitted from the terminal device 14 of the user X to the terminal device 14 of the partner user Y is set in the user information of the user X, and the user X's The transmission side information QS in the unit information U including the message M received by the terminal device 14 from the partner user Y's terminal device 14 is set in the user information of the partner user Y. Similarly, the receiving side information QR is user information of the user on the receiving side of the message M. Therefore, by referring to the transmission / reception history H, it is possible to specify the number of transmissions and receptions of the message M executed in the past with an arbitrary partner user Y. The time information QT designates the transmission / reception time of the message M (for example, the transmission time of the message M).

  As shown in FIG. 2, the control device 20 of each terminal device 14 executes a program stored in the storage device 22, and thereby a plurality of functions for exchanging messages M with other terminal devices 14. (Transmission / reception unit 32, information generation unit 34, display control unit 36) are realized. The program executed by the control device 20 is application software used for exchanging (chatting) the message M with other terminal devices 14, and is downloaded to the terminal device 14 in advance as native software and stored therein. 22 is stored.

  The transmission / reception unit 32 in FIG. 2 transmits and receives a message M to and from each partner user's terminal device 14. The information generation unit 34 updates each transmission / reception history H in the storage device 22 in response to transmission and reception of the message M by the transmission / reception unit 32. The display control unit 36 causes the display device 26 to display various images. For example, the display control unit 36 causes the display device 26 to sequentially display a time series of messages M exchanged between users.

  When the user X designates the message M and the other party user Y as the transmission destination by operating the input device 28, the transmission / reception unit 32 transmits the transmission side information QS that designates the user information of the user X and the other party user Y. The transmission information DS including the reception side information QR specifying the user information and the time information QT specifying the transmission time of the message M together with the message M is generated and transmitted from the communication device 24 to the management device 12 (step of FIG. 2). SA). The transmission information DS is transferred from the management device 12 to the terminal device 14 of the partner user Y designated as the transmission destination. The information generation unit 34 of the terminal device 14 of the user X transmits / receives the unit information U including the transmission side information QS, the reception side information QR, the time information QT, and the message M in the transmission information DS of this time to the other user Y. It adds to the history H (FIG. 3).

  On the other hand, transmission information DS transmitted from the terminal device 14 of the partner user Y includes transmission side information QS that specifies user information of the partner user Y and reception side information QR that specifies user information of the user X. The time information QT for designating the transmission time of the message M is included together with the message M. The transmission / reception unit 32 of the terminal device 14 of the user X receives the transmission information DS transmitted from the terminal device 14 of the partner user Y and passed through the management device 12 from the communication device 24 (step SB in FIG. 2). The information generation unit 34 obtains unit information U including the transmission side information QS, the reception side information QR, the time information QT, and the message M in the transmission information DS received from the terminal device 14 of the counterpart user Y. It adds to the transmission / reception history H.

  The display control unit 36 of the terminal device 14 of the user X causes the display device 26 to display the AC screen C of FIG. 4 in which the messages M exchanged between the user X and the partner user Y are arranged in time series. . As shown in FIG. 4, display information (for example, name) designated by the user information of the user who created the message M and the content of the message M are sequentially transmitted each time transmission information DS is transmitted or received by the transmission / reception unit 32. Is added to the AC screen C. That is, an arbitrary user X can perform a chat with a desired partner user Y.

  Further, when the user X instructs history confirmation by a predetermined operation on the input device 28, the display control unit 36 causes the display device 26 to display the history confirmation screen GA of FIG. 5 or the history confirmation screen GB of FIG. Each of the history confirmation screen GA and the history confirmation screen GB is an image that presents the user X with a history of transmission / reception of the message M between each partner user.

  The display control unit 36 determines for each partner user whether or not the transmission / reception history H stored in the storage device 22 satisfies a predetermined condition, and a plurality of partner users whose transmission / reception history H is stored in the storage device 22. The other party user whose transmission / reception history H satisfies a predetermined condition (hereinafter referred to as “default user”) YA and the other user whose transmission / reception history H does not satisfy a predetermined condition (hereinafter referred to as “new user”) YB And determine. The default user YA is a partner user who is presumed that a sufficient friendly relationship with the user X has already been formed by the exchange of the message M executed in the past, and the new user YB is the past user The message M is not exchanged sufficiently, and it is estimated that the friendship with the user X is not established.

  Specifically, the default user YA and the new user YB are determined according to whether or not the number of times of transmission / reception of the message M specified from the transmission / reception history H satisfies a predetermined condition. For example, the display control unit 36 sets the total number of times (hereinafter referred to as “the number of round trips”) K as a unit (one round) of the pair of transmission and reception of the message M (that is, round trip of the message M between users) for each partner. Calculated for each partner user from the transmission / reception history H of the user, and determines the partner user whose round trip number K is equal to or greater than the predetermined value KTH as the default user YA, while the round trip number K is below the predetermined value KTH. Is determined as a new user YB.

  Note that transmission and reception of the message M are not always performed alternately with a specific partner user. For example, when the transmission of the message M to a specific partner user is continuously performed a plurality of times (that is, without receiving the message M from the partner user between successive transmissions), There may be a case where the reception of the message M from a specific partner user is continuously executed a plurality of times. In the first embodiment, even when transmission or reception is continuously executed as described above, a pair of one transmission to a specific partner user and one reception from the partner user is used as a unit. The number of round trips K is counted. For example, when the transmission of the message M to a specific partner user is continuously executed three times and the reception of the message M from the partner user is continuously executed twice, the round-trip number K is Counted twice.

  The predetermined value KTH to be compared with the number of reciprocations K is set to 1, for example. That is, the transmission / reception unit 32 of the terminal device 14 of the user X transmits the message M one or more times, but the other user who has never received the response message M from the transmission destination and the terminal device of the user X 14, the transmitting / receiving unit 32 has received the message M one or more times, but the partner user who has not transmitted the response message M at least once from the terminal device 14 of the user X is determined as the new user YB, The transmission / reception unit 32 of the terminal device 14 of the user X has transmitted the message M one or more times and received the message M one or more times in the past (the message M is 1 between the user X and the user X). The partner user who has reciprocated more than once) is determined as the default user YA.

  The history confirmation screen GA in FIG. 5 is an image in which history information ZA is arranged for each default user YA. The new user YB is excluded from the display target in the history confirmation screen GA. As shown in FIG. 5, the history information ZA is information related to the history of transmission / reception of the message M executed in the past between the user X and the default user YA, specifically, the display information EA1 and transmission / reception. The time EA2 and the latest message EA3 are included.

  The display information EA1 is a code (for example, a name) representing the default user YA, and is specified from the user information of each unit information U in the transmission / reception history H of the default user YA. The transmission / reception time EA2 is the time when the user X and the default user YA last exchanged the message M (that is, the time specified by the time information QT of the latest unit information U). Each piece of history information ZA is arranged in time series in the order of transmission / reception time EA2. The latest message EA3 is the latest message M exchanged between the user X and the default user YA.

  The user X can select arbitrary history information ZA (for example, display information EA1) in the history confirmation screen GA by appropriately operating the input device 28. The display control unit 36 refers to the transmission / reception history H of the default user YA corresponding to the history information ZA selected by the user X, thereby arranging the messages M exchanged in the past by the user X and the default user YA. The exchange screen C (FIG. 4) is displayed, and the message M is exchanged between the user X and the default user YA. That is, the history confirmation screen GA is an image that presents a plurality of default users YA to the user X as partner candidates for transmission / reception of the message M by the transmission / reception unit 32.

  In addition to the history information ZA of each default user YA, an operator image B is arranged on the history confirmation screen GA of FIG. The operator image B is an element (command button) that receives an instruction from the user X. The user X can operate the operator image B by appropriately operating the input device 28. When the user X operates the operator image B, the display control unit 36 causes the display device 26 to display the history confirmation screen GB of FIG. 6 instead of the history confirmation screen GA of FIG.

  The history confirmation screen GB in FIG. 6 is an image in which history information ZB for each new user YB is arranged. Similar to the history information ZA, the history information ZB is information relating to the transmission / reception history of the message M between the user X and the new user YB. Specifically, the display information EB1, the transmission / reception time EB2, and the identification image And EB3. The display information EB1 is a code (for example, name) representing the new user YB, and is specified from the user information of the unit information U in the transmission / reception history H of the new user YB, for example. The transmission / reception time EB2 is a time (time specified by the time information QT of the unit information U) when the user X and the new user YB exchange the message M. The history information ZB in the history confirmation screen GB is arranged in time series in the order of the transmission / reception time EB2.

  As described above, the new user YB is the partner user whose transmission / reception unit 32 of the terminal device 14 of the user X has only transmitted the message M (the other party's usage in which the transmission / reception unit 32 has never received the message M). (Hereinafter referred to as "first user YB1"), or the other user (transmission / reception unit 32 sends the message M once) when the transmission / reception unit 32 of the terminal device 14 of the user X only receives the message M. Correspond to “the second user YB2”). The identification image EB3 is an image (image) for the user X to visually distinguish the first user YB1 and the second user YB2. Specifically, the display control unit 36 determines the new user YB as the first user YB1 and the second user YB2 according to the transmission / reception history H of each new user YB, and the first user YB1. The identification image EB3 and the identification image EB3 of the second user YB2 are displayed in different modes. In the example of FIG. 6, the identification image EB3 of the first user YB1 is a right-pointing arrow (image representing transmission from the user X), and the identification image EB3 of the second user YB2 is a left-pointing arrow (user (Image representing reception by X). Accordingly, each new user YB presented on the history confirmation screen GB is the first user YB1 who has only transmitted the message M, or the user X has only received the message M. There is an advantage that the user X can visually and intuitively recognize the second user YB2 by visually recognizing each identification image EB3.

  The user X can select arbitrary history information ZB (for example, display information EB1) in the history confirmation screen GB by appropriately operating the input device 28. The display control unit 36 refers to the transmission / reception history H of the new user YB corresponding to the history information ZB selected by the user X, so that the user X has transmitted or received in the past with the new user YB. The exchange screen C for displaying the message M is displayed, and the message M is exchanged between the user X and the new user YB. That is, the history confirmation screen GB is an image that presents a plurality of new users YB to the user X as partner candidates for transmission / reception of the message M by the transmission / reception unit 32. It should be noted that the total number of new users YB (the number of unread messages M from new users YB) that the user X does not display the message M among the plurality of new users YB is in the history confirmation screen GA of FIG. Is added to the operator image B (numerical value “4” in FIG. 5).

  As described above, in the first embodiment, the history information ZA of the default user YA whose transmission / reception history H satisfies the predetermined condition and the history information ZB of the new user YB whose transmission / reception history H does not satisfy the predetermined condition are separated. Separately, it is displayed on the display device 26. Accordingly, the history information ZA of each default user YA and the history information ZA of each new user YB are compared with the configuration in which both the history information ZA of each new user YB are arranged in time series, and the history information ZA of each default user YA is confirmed. There is an advantage that confirmation of the history information ZB of the user YB (and selection of each default user YA and selection of each new user YB) is facilitated. Particularly in the first embodiment, a history confirmation screen GA in which the history information ZA of each predetermined user YA is arranged is initially displayed on the display device 26, and a history confirmation screen GB in which the history information ZB of each new user YB is arranged. Is displayed when the user X explicitly instructs (operates the operator image B). That is, the history confirmation screen GB is not displayed unless the user gives an instruction. Accordingly, there is an advantage that the user X who does not wish to interact with the new user YB can check the history information ZA of each predetermined user YA without being aware of the existence of each new user YB.

  In the first embodiment, in particular, the other user is discriminated as the default user YA and the new user YB according to the number of times of transmission / reception of the message M between the users (specifically, the number of round trips K). The other party user (new user YB) who has not yet formed a friendly relationship with the other user (the default user YA) who has already formed a friendly relationship with the user X The advantage is that it can be properly distinguished. In general, when there is an intention to form a friendly relationship with another user, it responds to the message M from that user and is willing to form a friendly relationship with another user. If not, there is a general tendency not to respond to the message M from the user. In the first embodiment, the default user YA and the new user are newly determined depending on whether or not the round trip count K in the unit of transmission and reception of the message M (round trip of the message M between users) exceeds a predetermined value KTH. Since the user YB is distinguished, a special effect is realized in which it is possible to appropriately estimate whether or not there is an intention to establish a friendly relationship between the users.

Second Embodiment
A second embodiment of the present invention will be described below. In addition, about the element in which an effect | action and a function are equivalent to 1st Embodiment in each form illustrated below, the code | symbol referred by description of 1st Embodiment is diverted, and each detailed description is abbreviate | omitted suitably.

  The storage device 22 of the terminal device 14 of an arbitrary user X in the second embodiment stores relationship information that defines each partner user in which an AC relationship with the user X is registered. The relation information includes, for example, identification information of each partner user specified by the user X through an operation on the input device 28.

  The display control unit 36 according to the second embodiment refers to the relationship information stored in the storage device 22 to determine whether or not the AC relationship with the user X is registered (whether there is identification information in the relationship information). Is determined for each partner user. Then, the history information ZA is displayed on the history confirmation screen GA, with the partner user whose exchange relationship with the user X is registered as the default user YA together with the partner user whose transmission / reception history H satisfies the predetermined condition. In other words, the partner user whose exchange relationship with the user X is registered is determined as the default user YA regardless of whether or not the transmission / reception history H satisfies the predetermined condition. As will be understood from the above description, the partner user in which the exchange relationship between the partner user whose transmission / reception history H satisfies the predetermined condition and the user X is registered (whether or not the transmission / reception history H satisfies the predetermined condition is determined. The history information ZA of the default user YA, which is configured as “Unquestioned”, is displayed on the history confirmation screen GA, and the partner user (new usage) whose exchange relationship with the user X is not registered and whose transmission / reception history H does not satisfy the predetermined condition The history information ZB of the person YB) is displayed on the history confirmation screen GB.

  In the second embodiment, the same effect as in the first embodiment is realized. Further, in the second embodiment, the other user whose exchange relation with the user X is registered is selected as the default user YA regardless of whether or not the transmission / reception history H satisfies a predetermined condition. Therefore, even in the partner user who has registered the exchange relationship with the user X, when the transmission / reception history H does not satisfy the predetermined condition, compared with the configuration (for example, the first embodiment) determined as the new user YB, There is an advantage that the user X can easily select a partner user whose exchange relation with the user X is registered.

<Modification>
Each form illustrated above can be variously modified. Specific modifications are exemplified below. Two or more modes arbitrarily selected from the following examples can be appropriately combined within a range that does not contradict each other.

(1) In each of the above-described embodiments, the history confirmation screen GA in which the history information ZA of each default user YA is arranged and the history confirmation screen GB in which the history information ZB of each new user YB is arranged are selectively displayed on the display device 26. However, the configuration for distinguishing and displaying the history information ZA of each default user YA and the history information ZB of each new user YB is not limited to the above examples. For example, as shown in FIG. 7, a history confirmation screen G in which a region R1 in which history information ZA of each predetermined user YA is arranged and a region R2 in which history information ZB of each new user YB is arranged is defined. The configuration displayed on the display device 26, and as shown in FIG. 8, the history information ZA of each default user YA and the history information ZB of each new user YB are different from each other (for example, color, gradation, character type, etc.). A configuration may also be employed in which the history confirmation screen G arranged in a visually distinguishable manner) is displayed on the display device 26.

(2) In each of the above-described embodiments, the partner user is determined as the default user YA and the new user YB depending on whether or not the round-trip count K of the message M exceeds a predetermined value KTH. The method for discriminating between the default user YA and the new user YB is not limited to the above examples. For example, depending on whether the number of times the terminal device 14 of the user X has received the message M exceeds a predetermined value (regardless of the number of times the terminal device 14 of the user X has transmitted the message M), the default user YA A configuration for distinguishing from the new user YB, whether or not the number of times the terminal device 14 of the user X has transmitted the message M exceeds a predetermined value (the number of times the terminal device 14 of the user X has received the message M is irrelevant) ) To distinguish the default user YA from the new user YB.

  Also, a function for storing the transmission / reception history H of each partner user and a function for determining whether the transmission / reception history H of each partner user satisfies a predetermined condition (each partner user is designated as a default user YA and a new user). It is also possible to mount the function for determining YB) in the management device 12 (omitted from the terminal device 14). The display control unit 36 of the terminal device 14 acquires the discrimination result for each partner user from the management device 12 and causes the display device 26 to display the history confirmation screen GA and the history confirmation screen GB. As understood from the above description, the display control unit 36 according to the preferred embodiment of the present invention has the history information ZA and the transmission / reception history H of each partner user (default user YA) whose transmission / reception history H satisfies a predetermined condition. It is included as an element that distinguishes and displays the history information ZB of each partner user (new user YB) that does not satisfy the predetermined condition, and the specific content of the predetermined condition and the determination subject of the success or failure of the predetermined condition (the management device 12 and It is unquestioned which terminal device 14 determines).

(3) In each of the above-described forms, each new user YB is designated as the first user YB1 to which the terminal device 14 of the user X has transmitted the message M and the second user terminal 2 to which the terminal device 14 of the user X has received the message M. Although the user YB2 is discriminated, the method of discriminating each new user YB into the first user YB1 and the second user YB2 is not limited to the above examples.

  For example, in a configuration in which the predetermined value KTH is set to a numerical value of 2 or more, a partner user who has performed both transmission and reception of the message M with the user X (a partner user who has a round-trip count of one or more) However, since the user can be identified as a new user YB, the new user YB is designated as the first user YB1 and the second user YB2 according to the same standard as in the first embodiment (transmission / reception of the message M to the user X). Cannot be determined. Therefore, for example, each new user YB is discriminated as the first user YB1 and the second user YB2 according to the sender / recipient of the latest (last) message M exchanged with the user X. A configuration is adopted. For example, the display control unit 36, when the latest message M exchanged with the user X is transmitted from the user X to the new user YB (when the user X is the transmission side). The new user YB is selected as the first user YB1 and the latest message M exchanged with the user X is sent from the new user YB to the user X (user When X is the receiving side), the new user YB is selected as the second user YB2. Further, when the number of transmissions of the message M from the user X to the new user YB exceeds the number of transmissions of the message M from the new user YB to the user X (when the number of transmissions of the message M is higher for the user X). When the new user YB is selected as the first user YB1, and the number of transmissions of the message M from the new user YB to the user X exceeds the number of transmissions of the message M from the user X to the new user YB (new use) It is also possible to select the new user YB as the second user YB2 when the user YB has a larger number of transmissions of the message M).

  Also, it is possible to mount a function for discriminating each new user YB into the first user YB1 and the second user YB2 in the management device 12 (omitted from the terminal device 14). The display control unit 36 of the terminal device 14 acquires the determination result for each new user YB from the management device 12 and causes the display device 26 to display the history confirmation screen GB. As can be understood from the above description, the display control unit 36 according to the preferred embodiment of the present invention distinguishes the history information ZB between the first user YB1 and the second user YB2 determined according to the transmission / reception history H. It is included as an element to be displayed on the display device 26, and the specific determination method and determination subject (whether the management device 12 or the terminal device 14 determines) between the first user YB1 and the second user YB2 is not questioned. is there. It is also possible to omit the configuration for discriminating the new user YB into the first user YB1 and the second user YB2.

(4) In each of the above-described embodiments, the identification image (mark) EB3 that is different between the first user YB1 and the second user YB2 is displayed, but the first user YB1 and the second user YB2 are visually displayed. The method of distinguishing between is not limited to the above examples. For example, the history information ZB of the first user YB1 and the history information ZB of the second user YB2 are displayed in separate areas within one screen, or the history information ZB of the first user YB1 and the second user. A configuration in which the history information ZB of YB2 is displayed in a different form (for example, visually distinguishable properties such as color, gradation, and character type) may be employed. Further, the identification image EB3 for visually identifying the first user YB1 and the second user YB2 is not limited to a graphic image (mark). For example, for example, characters and symbols such as “transmission” and “reception” can be displayed as the identification image EB3.

(5) In each of the above-described embodiments, even when the transmission or reception of the message M with the partner user is continuously performed, the round trip is performed in units of a pair of one transmission and one reception of the message. Although the number of times K is counted, the method of counting the number of times of reciprocation K is appropriately changed. For example, it is also possible to count the number of round trips K, assuming that a plurality of consecutive transmissions are once and a plurality of consecutive receptions are one. For example, when the transmission of the message M to a specific partner user is continuously executed three times and the reception of the message M from the partner user is continuously executed twice, the round-trip number K is Counted once. The predetermined value KTH to be compared with the number of reciprocations K is appropriately selected according to the counting method of the number of reciprocations K. The first user YB1 and the transmission / reception unit 32 that the transmission / reception unit 32 executes only the transmission of the message M, regardless of whether the continuous transmission or reception over a plurality of times is counted as one time. A configuration in which the second user YB2 who has only received the message M is distinguished and displayed is preferable.

(6) In the second embodiment, the case where the relationship information is stored in each terminal device 14 is exemplified. However, a configuration in which the management device 12 stores the relationship information for each user may be employed. The display control unit 36 of the terminal device 14 of the user X inquires the management device 12 whether or not the exchange relationship with the user X is registered for each partner user, and the inquiry result transmitted from the management device 12 In response to this, the history confirmation screen GA or the history confirmation screen GB is displayed on the display device 26. Moreover, although each terminal device 14 illustrated the structure which transmits / receives the message M via the management apparatus 12 in each above-mentioned form, transmission / reception of the message M via the management apparatus 12 is not an essential requirement of this invention. In other words, the message M can be transmitted and received directly between the terminal devices 14 (that is, without going through the management device 12). Therefore, the management device 12 can be omitted.

(7) The contents of the history information ZA and the history information ZB are not limited to the above examples. For example, a configuration in which the transmission / reception time EA2 or the latest message EA3 is omitted from the history information ZA, or a configuration in which the transmission / reception time EB2 or the identification image EB3 is omitted from the history information ZB may be employed. The difference between the contents of the history information ZA and the history information ZB is not questioned. The contents of the display information EA1 of the history information ZA and the display information EB1 of the history information ZB are not limited to the name of the partner user. For example, an image of a partner user or a character (avatar) image representing the partner user is displayed as display information EA1 or display information EB1 together with the name of each partner user (or in place of the name of each partner user). It can also be used.
