CROSS REFERENCE TO RELATED APPLICATIONS 
     This application is based upon and claims the benefit of priority from Japanese patent application No. 2021-182082, filed on Nov. 8, 2021, the disclosure of which is incorporated herein in its entirety by reference. 
     BACKGROUND 
     The present disclosure relates to an article management system, an article management method, and an article management program. 
     Japanese Unexamined Patent Application Publication No. 2016-45665 discloses a system for automatically delivering articles to storage lockers partitioned into a plurality of storage spaces. 
     SUMMARY 
     It should be noted that, in the case where the sender of an article to be delivered sends information about the use of the article together with the article itself to a user of the article, the timing at which, for example, the article itself is delivered to the user is not necessarily appropriate as the timing at which the information is shown to the user. Since the information presented to the user is the information about the use of the delivered article, it is desirable if the information is presented to the user at the same timing as the timing at which the user uses the article. 
     In view of the above-described circumstances, an object of the present disclosure is to provide an article management system capable of presenting information about the use of a delivered article to a user of the article at the same timing as the timing at which the user uses the article. 
     A first exemplary aspect is an article management system configured to manage a delivered article by using a computer, the article management system being further configured to: 
     store identification information identifying an article to be delivered to a user thereof and use information about use of the article attached by a sender of the article while associating them with each other; and 
     read, when the user uses the article, the identification information attached to the article, and extract and output the use information associated with the identification information. 
     Further, another exemplary aspect is an article management method for managing a delivered article by using a computer, the article management method including: 
     storing identification information identifying an article to be delivered to a user thereof and use information about use of the article attached by a sender of the article while associating them with each other; and 
     reading, when the user uses the article, the identification information attached to the article, and extracting and outputting the use information associated with the identification information. 
     Further, another exemplary aspect is an article management program for managing a delivered article, the article management program being configured to cause a computer to perform: 
     storing identification information identifying an article to be delivered to a user thereof and use information about use of the article attached by a sender of the article while associating them with each other; and 
     reading, when the user uses the article, the identification information attached to the article, and extracting and outputting the use information associated with the identification information. 
     As described above, according to an aspect of the present disclosure, identification information identifying the article to be delivered to the user thereof and use information about the use of the article attached by the sender of the article are associated with each other and stored. Further, when the user uses the article, the identification information attached to the article is read, and the use information associated with the identification information is extracted and output. Therefore, it is possible to show the use information about the use of the delivered article to the user thereof at the same timing as the timing at which the user, who is the recipient of the article, uses the article. 
     An indoor robot capable of taking out an article stored indoors may store the identification information and the use information while associating them with each other, and when the user uses the article, the indoor robot may take out the stored article, deliver the article to the user, and extract and output the use information associated with the identification information. By the above-described configuration, it is possible to present the use information to the user when the indoor robot delivers the article to the user. 
     When the indoor robot takes out the stored article, the indoor robot may read the identification information attached to the article and extract the use information associated with the identification information. By the above-described configuration, it is possible to immediately extract the use information when the indoor robot takes out the article. 
     The indoor robot may erase the stored use information after taking out the stored article and outputting the use information. By the above-described configuration, the storage capacity can be saved. 
     According to the present disclosure, it is possible to provide an article management system capable of presenting information about the use of a delivered article to a user at the same timing as the timing at which the user uses the article. 
     The above and other objects, features and advantages of the present disclosure will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus are not to be considered as limiting the present disclosure.

     DESCRIPTION OF EMBODIMENTS 
     Specific embodiments will be described hereinafter in detail with reference to the drawings. The same or corresponding elements are denoted by the same reference numerals or symbols throughout the drawings, and redundant descriptions thereof are omitted as appropriate for clarifying the descriptions. 
     First Embodiment 
     Firstly, an article management system and an article management method according to a first embodiment will be described with reference to  FIG.  1   .  FIG.  1    is a block diagram of the article management system according to the first embodiment. The article management system according to the first embodiment is an article management system that manages delivered articles by using a computer. As shown in  FIG.  1   , the article management system according to this embodiment includes a user terminal  11 , a management server  20 , an EC (Electronic Commerce) server  30 , and a delivery terminal  40 . 
     In this embodiment, a user purchases an article from an EC site on the Internet managed by an EC vendor, and the article is delivered from the EC vendor, who is the sender, to the user, who is the recipient, by a deliverer (i.e., a person, a robot, or the like who delivers the article). 
     Each of the user terminal  11 , the management server  20 , the EC server  30 , and the delivery terminal  40  includes an arithmetic unit such as a CPU (Central Processing Unit), and a storage unit such as a RAM (Random Access Memory) and a ROM (Read Only Memory) in which various control programs and data are stored. That is, each of the user terminal  11 , the management server  20 , the EC server  30 , and the delivery terminal  40  has functions as a computer, and performs the below-described processes based on the various control programs and the like. 
     As shown in  FIG.  1   , the user terminal  11  is a communication terminal that is connected to the management server  20  through a cable or wirelessly so that the user terminal  11  can communicate with the management server  20 . The user terminal  11  is not limited to any particular terminal as long as it can communicate with the management server  20 . For example, the user terminal  11  may be a mobile communication terminal such as a smartphone or a tablet-type terminal, or a PC (Personal Computer) installed indoors. 
     Note that although the user terminal  11  is located in a living space (e.g., a living room) of a house in  FIG.  1   , the user terminal  11  may be located outside the living space in the house, or outside the house. Further, in this specification, the meaning of the term “living space” includes an office space. 
     As shown in  FIG.  1   , a user inputs order information oi to the user terminal  11 . The order information oi is transmitted from the user terminal  11  to the management server  20 . The order information oi is information about an article to be delivered, and includes, for example, information about a commodity name, a quantity, a desired delivery date, a delivery destination, and the like 
     Further, the user terminal  11  receives article identification information id and use information ui issued by the EC server  30  from the management server  20 , and stores the received article identification information id and the use information ui while associating them with each other. 
     Further, when the user uses the article, the user terminal  11  receives the article identification information id read by a reader  13 . Then, the user terminal  11  extracts and outputs the use information ui associated with the article identification information id. 
     The management server  20  is a server that manages the article management system. As shown in  FIG.  1   , the management server  20  is connected to the user terminal  11 , the EC server  30 , and the delivery terminal  40  so that the management server  20  can communicate with these apparatuses. The management server  20  is, for example, a cloud server. The management server  20  transmits order information oi received from the user terminal  11  to the EC server  30 . 
     Further, the management server  20  receives article identification information id and use information ui issued by the EC server  30 , and transmits them to the user terminal  11 . 
     Further, the management server  20  also transmits the article identification information id to the delivery terminal  40 . The article identification information id is information identifying the article to be delivered, and is, for example, an order number. 
     The EC server  30  is, for example, a server constituting an EC site on the Internet managed by an EC vendor. As shown in  FIG.  1   , the EC server  30 , which is connected to the management server  20  so as to be able to communicate with the management server  20 , issues article identification information id and use information ui according to the order information of received from the management server  20 , and transmits them to the management server  20 . 
     The use information ui is information about the use of the article, which the sender of the article sends to the user together with the article. The use information ui is information which the user, who is the recipient, should refer to when he/she uses the article. The use information ui is not limited to any particular information as long as it is information about the use of the delivered article. The use information ui includes, for example, a document(s) for the use of the article attached thereto and/or a manual(s) therefor. In the case where the delivered article is food, the use information ui includes, for example, information about a cooking method, a best-before date, an eat-by date, and the like of the article. 
     The delivery terminal  40  is, for example, a terminal carried by a deliverer, and is a communication terminal capable of reading the article identification information id attached to the article. As shown in  FIG.  1   , the delivery terminal  40  is connected to the management server  20  so as to be able to communicate with the management server  20 . The delivery terminal  40  receives the article identification information id from the management server  20 . By reading the article identification information id attached to the article by using the delivery terminal  40 , the deliverer can identify the article to be delivered. 
     Note that the delivery terminal  40  may be a delivery robot, and in such a case, the delivery robot may deliver the article on behalf of the deliverer. 
     The article identification information id is, for example, text (i.e., letters), a symbol, a bar code, a 2D (two-dimensional) code, a RFID (Radio Frequency IDentifier), or the like, and is directly or indirectly attached to the article to be delivered. More specifically, the article identification information id is directly stuck on the article or embedded in the article. Alternatively, the article identification information id may be indirectly attached to the article, such as being stuck on or embedded in the package of the article. Note that the package is not limited to any particular packages, and may be, for example, a box, a bag, or a sheet made of paper or vinyl. The package may be a disposable type, or may be a reusable type such as a returnable box. 
     Note that as shown in  FIG.  1   , the article with the article identification information id attached thereto is delivered from the EC vendor to the user by the deliverer. 
     Note that when the delivery of the article is completed, the user does not necessarily have to receive the article. That is, it is sufficient if the article arrives at the house. For example, the article may be placed in a predetermined place (e.g., a delivery box or the like) in the house. Alternatively, a robot may receive the article which will be described later in detail. 
     In the example shown in  FIG.  1   , the delivered article is stored in a storage place by the user. In the example shown in  FIG.  1   , a reader  13  for reading the article identification information id is provided in the storage place. The reader  13  is connected to the user terminal  11  so as to be able to communicate with the user terminal  11 . When the delivered article is stored in the storage place, the article identification information id attached to the article is read by using the reader  13  and transmitted to the user terminal  11 . Therefore, by the user terminal  11 , the user can check whether the article is stored in the storage place. 
     Further, when the user takes out the delivered article from the storage place, the article identification information id attached to the article is read by using the reader  13  and transmitted to the user terminal  11 . Then, by the user terminal  11 , the use information ui associated with this article identification information id is extracted and output for the user. 
     Note that the reader  13  may or may not be fixed to the storage location. 
     As described above, in the article management system according to this embodiment, the user terminal  11  stores the article identification information id for identifying the article to be delivered to the user and the use information ui about the use of the article while associating them with each other. When the user takes out the article from the storage place and uses the article, the article identification information id attached to the article is read by the reader  13 , and the article identification information id is transmitted from the reader  13  to the user terminal  11 . 
     Then, by the user terminal  11 , the use information ui associated with this article identification information id is extracted and output for the user. For example, the use information ui is output in the form of text (i.e., letters), still images, moving images, or the like on the monitor of the user terminal  11 . Alternatively, the use information ui is output as voice (e.g., speech) from the speaker of the user terminal  11 . Needless to say, the use information ui may be simultaneously output on the monitor and from the speaker as text or the like and as voice, respectively. 
     As described above, in the article management system according to this embodiment, it is possible to present the information about the use of the delivered article to the user at the same timing as the timing at which the user uses the article. 
     Note that, in this embodiment, the management server  20 , instead of the user terminal  11 , may store the article identification information id and the use information ui while associating them with each other. When the user takes out the article from the storage place and uses the article, for example, the user terminal  11  transmits the article identification information id received from the reader  13  to the management server  20 . Upon receiving the article identification information id, the management server  20  extracts the use information ui associated with the article identification information id and transmits the extracted use information ui to the user terminal  11 . Then, the user terminal  11  may output the use information ui received from the management server  20  for the user. 
     Second Embodiment 
     Next, an article management system and an article management method according to a second embodiment will be described with reference to  FIG.  2   .  FIG.  2    is a block diagram of the article management system according to the second embodiment. 
     As shown in  FIG.  2   , the article management system according to this embodiment includes an indoor robot  12  in addition to the user terminal  11 , the management server  20 , the EC server  30 , and the delivery terminal  40  shown in  FIG.  1   . 
     In the article management system according to the first embodiment shown in  FIG.  1   , the management server  20  receives article identification information id and use information ui issued by the EC server  30 , and transmits them to the user terminal  11 . In contrast to this, in the article management system according to the second embodiment shown in  FIG.  2   , the management server  20  receives article identification information id and use information ui that are issued by the EC server  30  according to order information oi, and transmits them to the indoor robot  12  instead of transmitting to the user terminal  11 . 
     The indoor robot  12  is connected to the management server  20  so as to be able to communicate with the management server  20 , and stores the use information ui and the article identification information id received from the management server  20  while associating them with each other. The indoor robot  12  also includes, for example, an arithmetic unit and a storage unit in which various control programs, data, and the like are stored, has functions as a computer, and performs the below-described processes based on the various control programs. 
     Note that the indoor robot  12  is a robot that can move indoors. The indoor robot  12 , which includes, for example, an arm(s) for grasping an article, receives the delivered article from the deliverer and stores the received article in a predetermined storage place. Further, the indoor robot  12  takes out an article stored in the storage place and delivers the article to the user. 
     As shown in  FIG.  2   , when the user uses the article, the indoor robot  12  takes out the article from the storage place and delivers the article to the user. When doing so, the indoor robot  12  reads the article identification information id attached to the article, extracts the use information ui associated with the article identification information id, and outputs the extracted use information ui for the user. That is, the indoor robot  12  has the function of the reader  13  shown in  FIG.  1   . 
     As described above, in the article management system according to this embodiment, it is also possible to present the information about the use of the delivered article to the user at the same timing as the timing at which the user uses the article. 
     Note that the indoor robot  12  may not have the function of the reader, and instead, for example, a reader  13  for reading article identification information id may be separately provided in the storage place as shown in  FIG.  1   . 
     Further, the indoor robot  12  may erase the stored use information ui after taking out the article from the storage place and outputting the use information ui. This makes it possible to save the storage capacity. 
     The rest of the configuration is similar to that of the first embodiment, and therefore the description thereof is omitted.

     As shown in  FIG.  6   , when the user uses the article, the indoor robot  12  takes out the article from the storage place and delivers the article to the user. When doing so, the indoor robot  12  reads the article identification information id attached to the article, extracts the use information ui associated with the article identification information id, and outputs the extracted use information ui for the user. That is, the indoor robot  12  has the function of the reader  13  shown in  FIG.  1   . 
     As described above, in the article management system according to this embodiment, it is also possible to present the information about the use of the delivered article to the user at the same timing as the timing at which the user uses the article. 
     Note that the indoor robot  12  may not have the function of the reader, and instead, for example, a reader  13  for reading article identification information id may be separately provided in the storage place as shown in  FIG.  1   . 
     Further, in  FIG.  6   , the management server  20 , instead of the indoor robot  12 , may store the article identification information id and the use information ui while associating them with each other. When the user takes out the article from the storage place and uses the article, for example, the indoor robot  12  transmits the article identification information id, which is read by the indoor robot  12 , to the management server  20 . Upon receiving the article identification information id, the management server  20  extracts the use information ui associated with the article identification information id and transmits the extracted use information ui to the indoor robot  12 . Then, the indoor robot  12  may output the use information ui received from the management server  20  for the user. 
     Further, the first embodiment and this embodiment can be combined with each other. In such a case, instead of the indoor robot  12 , the user terminal  11  may store the use information ui and the article identification information id received from the management server  20  while associating them with each other. 
     The rest of the configuration is similar to that of the third embodiment shown in  FIG.  5   , and therefore the description thereof is omitted.

     In the article management system according to the fourth embodiment shown in  FIG.  6   , the management server  20  transmits the article identification information id and the use information ui to the indoor robot  12 . In contrast to this, in the article management system according to the first modified example shown in  FIG.  7   , the management server  20  transmits the article identification information id and the use information ui to the user terminal  11  instead of transmitting to the indoor robot  12 . The user terminal  11  stores the article identification information id and the use information ui received from the management server  20  while associating them with each other. Note that only the article identification information id is transmitted from the management server  20  to the indoor robot  12 . 
     As shown in  FIG.  7   , when the user uses the article, the indoor robot  12  takes out the article from the storage place and delivers the article to the user. When doing so, the indoor robot  12  reads the article identification information id attached to the article and transmits the article identification information id to the user terminal  11 . That is, the indoor robot  12  has the function of the reader  13  shown in  FIG.  1   . Then, the user terminal  11  extracts the use information ui associated with the article identification information id and outputs the extracted use information ui for the user. 
     As described above, in the article management system according to the first modified example, it is also possible to present the information about the use of the delivered article to the user at the same timing as the timing at which the user uses the article. 
     Note that the indoor robot  12  may not have the function of the reader, and instead, for example, a reader  13  for reading article identification information id may be separately provided in the storage place as shown in  FIG.  1   . 
     The rest of the configuration is similar to that of the fourth embodiment shown in  FIG.  6   , and therefore the description thereof is omitted.
