表示システム及び物品情報表示方法  Display system and article information display method
技術分野  Technical field
[0001] 本発明は、所定の位置に配置される商品や閲覧物などの物品情報を、所定の位置 に対応して配置された表示装置で表示する表示システム及び物品情報表示方法に 関する。  [0001] The present invention relates to a display system and an article information display method for displaying article information such as products and browsed articles arranged at a predetermined position on a display device arranged corresponding to the predetermined position.
背景技術  Background art
[0002] スーパーマーケットなどでは、商品が陳列棚に陳列されるが、商品名や価格などを 表示する必要があり、陳列した商品の近くに、商品名や価格などを記載した札を配置 している。この札は、従来は紙に記載したものが一般的であった力 近年小型で簡単 な表示のみを行う液晶表示装置などを利用することが行われている。  [0002] In supermarkets, etc., products are displayed on display shelves, but it is necessary to display product names, prices, etc., and tags with product names, prices, etc. are placed near the displayed products. . In the past, this tag was generally printed on paper. In recent years, a small liquid crystal display device that performs only simple display has been used.
[0003] また、図書館などでも、雑誌などの一部の書籍については雑誌棚に置かれ、雑誌 棚に雑誌名や月号などを表示することが行われている。  [0003] Also, in libraries and the like, some books such as magazines are placed on magazine shelves, and magazine names and month names are displayed on the magazine shelves.
[0004] 紙製の札は、表示スペースが限られており、頻繁に書き換える必要があるため、商 品の場合には商品名と価格などしか表示せず、書籍の場合には書籍名や作者など が表示されるだけであった。  [0004] Since paper tags have limited display space and need to be rewritten frequently, only the product name and price are displayed in the case of a product, and the book name and author in the case of a book. Etc. were only displayed.
[0005] 特許文献 1は、商品の陳列情報を表示する電子ペーパーを陳列棚に対応させて配 置し、商品の改廃や価格の変更に伴う表示情報の変更を無線通信により各電子べ 一パーに送信して、棚札表示の内容を容易に短時間で変更可能にしたシステムを記 載している。  [0005] In Patent Document 1, electronic paper that displays product display information is arranged in correspondence with display shelves, and changes in display information associated with product abolition or price changes are communicated to each electronic device by wireless communication. This is a system that can easily change the contents of the shelf label display in a short time.
[0006] また、特許文献 2は、商品の値札情報ではな 、が、表示情報を受信可能である非 接触 IC (電子)ダグを表示装置に設けて、表示装置の表示内容をリアルタイムに書き 換える電子表示媒体を記載して!/ヽる。  [0006] In addition, Patent Document 2 provides a non-contact IC (electronic) doug that can receive display information, but not product price tag information, and rewrites display contents of the display device in real time. Describe electronic display media! / Speak.
[0007] 特許文献 1 :特開 2004— 334415  [0007] Patent Document 1: JP-A-2004-334415
特許文献 2:特開 2004— 29259  Patent Document 2: JP-A-2004-29259
発明の開示  Disclosure of the invention
発明が解決しょうとする課題 [0008] 客は、陳列棚に陳列された商品を手にとって見て、購入しない場合には元の位置 に商品を戻すが、商品の陳列位置に対応して配置された札は商品名と価格が表示 されているだけであり、付近に類似の商品が存在する場合、どこの位置に戻すべきか 分力もなくなる場合がある。特に、取り上げた商品が最後の一個である場合、同じ商 品を探してその位置に戻すということも行えない。そのため、商品の陳列状態が混乱 して、札と商品の対応が取れなくなり、後の客が商品名や価格を誤って認識するとい う問題が生じる。 Problems to be solved by the invention [0008] The customer looks at the merchandise displayed on the display shelf and returns the merchandise to the original position if he / she does not purchase, but the tag placed in accordance with the merchandise display position has the merchandise name and price. If there is a similar product in the vicinity, there may be no power to determine where to return. In particular, if the product is the last one, it is not possible to search for the same product and return it to that position. For this reason, the display state of the product is confused, and the correspondence between the tag and the product cannot be obtained, and the problem arises that the customer later recognizes the product name and price incorrectly.
[0009] また、これまで商品が陳列されているか、すなわち商品が品切れになっていないか については、特に検出などは行われておらず、商品が陳列されている場合も、品切 れで商品が陳列されて!、な 、場合も、商品名と価格を表示した札はそのままであり、 電気的に書き換え可能な表示装置が使用される場合も、表示が変更されることはな かった。そのため、客は、品切れで陳列されていない商品については、品切れである か分力もず、たとえ品切れであることが分力つても価格以外の情報を得ることができ ず、その商品に対してそれ以上の関心を持たせるのが難しいために、販売の機会が 損なわれると!/、う問題が生じる。  [0009] Further, whether or not the product has been displayed so far, that is, whether or not the product is out of stock, is not particularly detected, and even when the product is displayed, the product is out of stock. In this case, the tag displaying the product name and price remains the same, and even when an electrically rewritable display device is used, the display was not changed. For this reason, the customer is out of stock or has no power for a product that is out of stock and cannot obtain information other than the price even if the product is out of stock. If it is difficult to raise the above interests, it will cause problems if sales opportunities are impaired.
[0010] 上記のような問題は、図書館の雑誌棚や本棚についても同様に生じ、表示が見に くいため閲覧した書籍を誤った位置に戻し、書籍の配列が混乱するという問題や、書 籍が雑誌棚や本棚にない理由が分力 ず、いつ所定の位置に書籍が戻る予定力も 容易には把握できないために閲覧をあきらめるため、実質的な利用効率が低下する という問題が生じる。  [0010] The above problems also occur in library magazine shelves and bookshelves, and it is difficult to see the display, so the book that was viewed is returned to the wrong position, and the book arrangement is confused. However, the reason why the book is not in the magazine shelf or the bookshelf is not enough, and the ability to return the book to the predetermined position cannot be easily grasped.
[0011] 陳列されている商品に関する情報を得るために、商品に付された QRコードやバー コードをカメラ付携帯電話などで読み取り、読み取ったコードに対応する商品情報を 携帯電話のディスプレイに表示することも提案されているが、カメラ付携帯電話が必 要な上、商品情報を送信するシステムが大規模になるので容易に実現できない。ま た、 QRコードやバーコードの代わりにステガノグラフィー(電子すかし)を利用すること も提案されているが、同様の問題がある。  [0011] In order to obtain information about the displayed product, the QR code or bar code attached to the product is read with a mobile phone with a camera, etc., and the product information corresponding to the read code is displayed on the mobile phone display. Although it has been proposed, a camera-equipped mobile phone is required, and the system for transmitting product information becomes large and cannot be easily realized. It has also been proposed to use steganography (electronic watermark) instead of QR codes and barcodes, but there are similar problems.
[0012] 近年、 RFIDなどの微小な電子 (IC)タグを商品に付けて、会計処理や盗難防止に 使用することが行われており、タグリーダ (RFIDリーダ)により読み取ったタグ情報を 表示することも行われている。しかし、商品が陳列されている力 、ないか、すなわち商 品が品切れになって!/、な!/、かにつ 、ては、特に検出などは行われて!/、なかった。 [0012] In recent years, RFID and other small electronic (IC) tags have been attached to products and used for accounting and theft prevention. Tag information read by a tag reader (RFID reader) is used. Displaying is also done. However, there was no power to display the merchandise, that is, the merchandise was out of stock! /, Na! /, And in particular, no detection was done! /.
[0013] 本発明は、物品に関する情報を適切に表示する新しい表示システム及び表示方法 の実現を目的とする。 [0013] An object of the present invention is to realize a new display system and display method for appropriately displaying information on articles.
課題を解決するための手段  Means for solving the problem
[0014] 上記目的を実現するため、本発明の表示システム及び物品表示方法は、物品に電 子タグを付け、物品が配置される所定位置に対応付けて電子タグの情報を読み取る タグリーダ及び物品の情報を表示する表示装置を設け、タグリーダが電子タグの情 報を検出する力しないか、すなわち所定の物品があるかないかに応じて、表示装置 の表示を変化させることを特徴とする。  [0014] In order to achieve the above object, the display system and the article display method of the present invention attach an electronic tag to an article and read information on the electronic tag in association with a predetermined position where the article is placed. A display device for displaying information is provided, and the display on the display device is changed according to whether the tag reader does not have the power to detect information on the electronic tag, that is, whether there is a predetermined article.
[0015] 本発明によれば、タグリーダ及び表示装置が物品の配置位置と対応付けて配置さ れるため、物品の有無が検出可能であり、物品の有無に応じた表示が可能になる。  [0015] According to the present invention, since the tag reader and the display device are arranged in association with the arrangement position of the article, it is possible to detect the presence / absence of the article and display according to the presence / absence of the article.
[0016] 物品がある場合には、物品の実物が存在するので物品の画像などを表示する必要 はなぐ物品の情報などの物品有り状態用表示が行われる。物品が無い場合には、 物品の画像、商品の在庫状況や次回の入荷予定日時、書籍の貸し出し状況などの 物品が所定の位置に配置される状態になることに関係する情報、及び物品の情報な どの物品無し状態用表示が行われる。これにより、物品が無い場合にもどのような物 品で、何時になれば物品が実際に手にできるかが分力るようになる。  [0016] When there is an article, since there is an actual article, an article presence state display such as article information that does not need to be displayed is performed. If there is no article, information related to the article being placed at a predetermined position, such as the image of the article, the inventory status of the product, the next scheduled arrival date and time, the book lending status, etc. A display for the state of no article is performed. As a result, it is possible to divide what kind of goods when there are no goods and what time the goods can actually be obtained.
[0017] 所定の位置に配置される物品は 1個とは限らず、複数種類の物品が複数個配置さ れる場合も対応できることが望ましい。電子タグリーダは、異なる情報を出力する複数 種類の電子タグを識別することが可能であり、表示装置は、複数種類の物品のそれ ぞれの有無状態に応じて、物品有り状態用表示または物品無し状態用表示を行う。 また、同一の情報を出力する複数個の同一種類の物品については、 1つでも電子タ グ情報を検出する時、すなわち 1つでも物品を検出する時には物品有り状態用表示 を行い、電子タグ情報を 1つも検出しない時には、物品無し状態用表示を行う。  [0017] The number of articles arranged at a predetermined position is not limited to one, and it is desirable that a plurality of types of articles can be arranged. The electronic tag reader can identify multiple types of electronic tags that output different information, and the display device can display the presence of an article or no article depending on the presence / absence state of each of multiple types of articles. Display for status. In addition, for a plurality of articles of the same type that output the same information, when at least one electronic tag information is detected, that is, when at least one article is detected, an article presence state display is performed, and the electronic tag information is displayed. When no item is detected, a display for the no article state is performed.
[0018] 客が商品を購入したかは、会計カウンタのレジスタのデータを管理する POSデータ システム力も得ることができるので、そのような情報を商品情報として表示するようにし ても良い。また、購入はしないが、客が商品を手にとる回数が多い場合には、商品の 注目度が高いと判断される。客が商品を手にとった後所定位置に戻す場合、タグリー ダは電子タグの情報を検出する状態と電子タグの情報を検出しない状態との間で変 ィ匕すること〖こなる。そこで、この変化を計数するカウンタを設けて、その計数値力ゝら物 品の注目度を算出し、注目度を表示するようにしてもよい。複数種類および Zまたは 複数個の電子タグが対象の場合には、各種類の電子タグについてタグリーダが検出 する電子タグの個数の変化を計数する。 [0018] Whether a customer has purchased a product can also be obtained as a POS data system that manages the data in the register of the accounting counter. Therefore, such information may be displayed as product information. Also, if you do not make purchases but customers often pick up products, It is judged that the degree of attention is high. When a customer picks up a product and returns it to a predetermined position, the tag reader changes between a state in which information on the electronic tag is detected and a state in which information on the electronic tag is not detected. Therefore, a counter for counting this change may be provided to calculate the attention level of the product, such as the count value force, and display the attention level. When multiple types and Z or multiple electronic tags are targeted, the change in the number of electronic tags detected by the tag reader is counted for each type of electronic tag.
[0019] 表示装置及びタグリーダは、物品が配置される位置に対応して設ける必要がある。  [0019] The display device and the tag reader need to be provided corresponding to the position where the article is arranged.
例えば、表示装置及びタグリーダの上に透明な載置台を設け、その上に物品を配置 するようにしてもよい。この場合、表示装置の表示面を大きくできるので、物品無し状 態用表示で物品の画像を大きく表示することも可能であり、その位置にどのような物 品があつたの力を明瞭に表示できる。これにより、物品を戻す位置を誤る頻度が低減 され、物品がない場合にもどのような物品力認識できる。なお、物品がある場合には 表示装置の表示面が見えないため、物品有り状態用表示は何も表示しないか、物品 がある部分は避けて表示を行う。  For example, a transparent mounting table may be provided on the display device and the tag reader, and the article may be placed thereon. In this case, since the display surface of the display device can be enlarged, it is also possible to display a large image of the article on the display for the article-free state, and clearly display what power the product has at that position. it can. As a result, the frequency with which the position to return the article is erroneous is reduced, and any article force can be recognized even when there is no article. If there is an article, the display surface of the display device cannot be seen. Therefore, the display for the article presence state displays nothing or avoids the part with the article.
[0020] 更に、載置台を複数の領域に分割し、各領域にタグリーダを設ければ、どの領域に 物品が配置され、どの領域に物品が配置されていないかを検出可能になる。この場 合、いずれかのタグリーダが検出した電子タグの情報に対応する物品情報を表示す る場合、電子タグの情報を検出したタグリーダの設けられた領域に隣接する領域に 空き領域があるかを検出し、表示装置の空き領域に対応する部分に物品の情報を表 示する。  [0020] Furthermore, if the mounting table is divided into a plurality of areas and a tag reader is provided in each area, it is possible to detect in which area the article is placed and in which area the article is not placed. In this case, when displaying article information corresponding to the information of the electronic tag detected by one of the tag readers, it is determined whether there is an empty area in the area adjacent to the area where the tag reader that detected the information of the electronic tag is provided. Detect and display article information in the part corresponding to the empty area of the display device.
[0021] 上記のような表示を行う表示装置は、低コストで、占有空間が小さぐ低消費電力で あることが要求されるので、電子ペーパーを使用することが望ま U、。  [0021] Since a display device that performs display as described above is required to be low-cost, low-power consumption with a small occupied space, it is desirable to use electronic paper.

Further, when the recognition / display unit and the server unit are provided as a common device at the same position, the transmission units 15 and 27 and the reception units 16 and 21 can be omitted. In this case, a communication path is required for exchanging information with the device that stores the POSDB23 and the attention ranking DB24.
[0027] 図 2は、実施形態の物品情報表示システムの基本動作を示すフローチャートである 。ステップ 101では、タグリーダ 11が RFIDタグ 2の信号を受信しているかいないかを 、タグ解析部 12が確認し、ノ ッファ 13、送信部 15及び受信部 21を介して制御部 22 に送る。 RFIDタグ 2の信号を受信した時には物品が所定の場所に置かれていること を意味し、 RFIDタグ 2の信号を受信しない時には物品が所定の場所に置かれてい ないことを意味する。 FIG. 2 is a flowchart showing the basic operation of the article information display system of the embodiment. In step 101, the tag analysis unit 12 confirms whether or not the tag reader 11 has received the signal of the RFID tag 2, and sends the signal to the control unit 22 via the notch 13, the transmission unit 15, and the reception unit 21. When the signal of the RFID tag 2 is received, it means that the article is placed in a predetermined place. When the signal of the RFID tag 2 is not received, it means that the article is not placed in a predetermined place.
[0028] ステップ 101で RFIDタグ 2の信号を受信した場合にはステップ 102に進み、タグ解 析部 12が受信したタグ信号を解析してタグ情報を分離し、カウンタ 14がタグ信号の 変化を計数し、タグ情報及び計数値をバッファ 13、送信部 15及び受信部 21を介し て制御部 22に送る。  [0028] When the signal of the RFID tag 2 is received in step 101, the process proceeds to step 102, where the tag analysis unit 12 analyzes the tag signal received to separate the tag information, and the counter 14 detects the change of the tag signal. Counting is performed, and tag information and a count value are sent to the control unit 22 via the buffer 13, the transmission unit 15, and the reception unit 21.
[0029] ステップ 103では、制御部 22が、計数値に応じて注目度ランキング DB24を更新す ると共に、 POSDB23、注目度ランキング DB24及び物品情報 DB25からタグ情報に 対応する情報を読み出し、表示制御部 26が所定の場所に置かれた物品のタグ情報 に対応する表示情報を生成する。  [0029] In step 103, the control unit 22 updates the attention level ranking DB 24 according to the count value, and reads information corresponding to the tag information from the POSDB 23, the attention level ranking DB 24, and the article information DB 25 to display the display control unit. 26 generates display information corresponding to tag information of articles placed in a predetermined place.
[0030] ステップ 104では、表示制御部 26が、生成した表示情報を送信部 27及び受信部 1 6を介して表示装置 17に送り、表示装置 17が表示情報を表示する。  [0030] In step 104, the display control unit 26 sends the generated display information to the display device 17 via the transmission unit 27 and the reception unit 16, and the display device 17 displays the display information.
[0031] 一方、ステップ 101で RFIDタグ 2の信号を受信しない場合にはステップ 105に進 み、制御部 22は、その時点でタグリーダ 11による信号の有無を判定している認識- 表示部がどの位置に配置されたものであるかを示す位置情報を確認する。もし認識' 表示部とサーバー部が 1対 1に対応するように設けられて 、る場合には、このステップ 105は不要である。 [0031] On the other hand, if the RFID tag 2 signal is not received in step 101, the process proceeds to step 105. Therefore, the control unit 22 confirms position information indicating where the recognition-display unit that determines the presence or absence of a signal from the tag reader 11 at that time is located. If the recognition display unit and the server unit have a one-to-one correspondence, this step 105 is not necessary.
[0032] ステップ 106では、制御部 22力 POSDB23、注目度ランキング DB24及び物品 情報 DB25から位置情報に対応する情報を読み出し、表示制御部 26がその場所に 置かれる物品に関する表示情報を生成する。  In step 106, information corresponding to the position information is read from the control unit 22 force POSDB 23, the attention ranking DB 24, and the item information DB 25, and the display control unit 26 generates display information about the item placed at the place.
[0033] ステップ 107では、表示制御部 26が、生成した表示情報を送信部 27及び受信部 1 6を介して表示装置 17に送り、表示装置 17が表示情報を表示する。  In step 107, the display control unit 26 sends the generated display information to the display device 17 via the transmission unit 27 and the reception unit 16, and the display device 17 displays the display information.
[0034] 実施形態の物品情報表示システムの基本構成及び動作を説明したが、各種の応 用にこの基本構成を適用することが可能であり、以下実施例を説明する。  [0034] The basic configuration and operation of the article information display system of the embodiment have been described, but the basic configuration can be applied to various applications, and examples will be described below.
[0035] 図 3は、本発明を適用した第 1実施例のスーパーマーケットなどの商品棚の外観を 示す図である。第 1実施例の表示システムでは、区切られた商品棚 32A— 32Eに対 応して設けられており、図 1に示した認識'表示部 10Aが商品棚 32A— 32Eのそれ ぞれに対応して設けられている。図 3では、表示装置 31A— 31E力 商品棚 32A— 32Eの上部に設けられている。表示装置 31A—31Eは、グラフィック表示が行えれば どのようなものでもよいが、表示を頻繁に変更する必要はないので電子ペーパーを 使用する。電子ペーパーは、低コストで、占有空間が小さぐ低消費電力ので、実施 例の表示装置として有利である。また、図示していないが、商品に付けられた RFID タグ 2の信号を検出するタグリーダ 11が商品棚 32A—32Eに対応して、例えば、商 品棚 32A— 32Eの下部に設けられており、商品棚 32A— 32Eのそれぞれに置かれ た商品に付された RFIDタグの信号を読み取るように構成されている。  FIG. 3 is a diagram showing the appearance of a product shelf such as a supermarket of the first embodiment to which the present invention is applied. In the display system of the first embodiment, the product shelves 32A-32E separated are provided, and the recognition display 10A shown in FIG. 1 corresponds to each of the product shelves 32A-32E. Is provided. In FIG. 3, the display devices 31A-31E are provided on the top of the product shelves 32A-32E. The display devices 31A-31E may be anything as long as they can perform graphic display, but electronic paper is used because it is not necessary to change the display frequently. Electronic paper is advantageous as a display device of the embodiment because it is low-cost and has low space consumption and low power consumption. Although not shown, a tag reader 11 for detecting the signal of the RFID tag 2 attached to the product is provided corresponding to the product shelf 32A-32E, for example, below the product shelf 32A-32E. It is configured to read RFID tag signals attached to the products placed on each of the product shelves 32A-32E.
[0036] 第 1実施例の表示システムでは、商品棚 32A—32Eに対応して設けられた 5個の 認識 ·表示部は、 1個のサーバー部 20に通信経路で接続されている。なお、他の商 品棚に対応して設けられた複数の認識 ·表示部が更にこのサーバー部 20に通信経 路で接続に接続されるように構成することも可能である。サーバー部 20は、店舗全体 を制御するシステムと通信経路で接続されており、各商品についての販売データや 仕入れデータなどを得て、 POSDB23に記憶するように構成されている。また、物品 情報 DB25には、商品種別番号に対応して商品情報が記憶されている。なお、 POS DB23、注目度ランキング DB24、物品情報 DB25をサーバー部 20に設けずに、通 信経路を介して随時店舗全体の管理システムカゝら得るようにしてもよい。 In the display system of the first embodiment, the five recognition / display units provided corresponding to the product shelves 32A-32E are connected to one server unit 20 via a communication path. A plurality of recognition / display units provided corresponding to other product shelves can be further connected to the server unit 20 via a communication path. The server unit 20 is connected to a system that controls the entire store via a communication path, and is configured to obtain sales data and purchase data for each product and store them in the POSDB 23. Also goods The information DB 25 stores product information corresponding to the product type number. The POS DB 23, the attention ranking DB 24, and the article information DB 25 may be obtained from the management system for the entire store at any time via the communication path without providing the server unit 20 with the POS DB 23.
[0037] 各商品棚には位置番号が付され、所定の商品が置かれ、商品棚の位置番号と商 品種別番号の関係がサーバー部 20に記憶されている。第 1実施例では、 1つの商品 棚には 1種類の商品が複数個置かれる。  Each product shelf is assigned a position number, a predetermined product is placed, and the relationship between the position number of the product shelf and the number for each product type is stored in the server unit 20. In the first embodiment, a plurality of one type of products are placed on one product shelf.
[0038] 図 4は、第 1実施例のシステムの動作を示すフローチャートである。上記のように、 1 つのサーバー部で複数の商品棚の表示装置 31A— 31Eを制御するので、制御は複 数の認識'表示部をスキャンしながら時分割で行われる。そこで、ステップ 201では、 対象となる商品棚の位置番号を確認する。  FIG. 4 is a flowchart showing the operation of the system of the first embodiment. As described above, since a plurality of product shelf display devices 31A-31E are controlled by one server unit, the control is performed in a time-sharing manner while scanning a plurality of recognition 'display units. Therefore, in step 201, the position number of the target product shelf is confirmed.
[0039] ステップ 202では、タグリーダ 11がタグ信号を検出して 、るかを判定する。タグ信号 が検出されている時には、対応する商品棚に 1個以上の商品が置かれていることを 意味し、タグ信号が検出されていない時には、対応する商品棚に商品が置かれてい ないことを意味する。 RFIDタグ 2の信号が検出された場合にはステップ 203に進み、 RFIDタグ 2の信号が検出されない場合にはステップ 206に進む。  In step 202, it is determined whether the tag reader 11 detects a tag signal. When a tag signal is detected, it means that one or more products are placed on the corresponding product shelf. When no tag signal is detected, no product is placed on the corresponding product shelf. Means. When the signal of the RFID tag 2 is detected, the process proceeds to step 203, and when the signal of the RFID tag 2 is not detected, the process proceeds to step 206.
[0040] ステップ 203では、検出したタグ信号を解析して商品種別番号、固体識別番号など のタグ情報を得て、それに対応する商品情報をデータベース力も読み取る。  [0040] In step 203, the detected tag signal is analyzed to obtain tag information such as a product type number and a solid identification number, and the product information corresponding to the tag information is also read.
[0041] ステップ 204では、読み取った商品情報に基づいて商品有り状態用表示を生成し 、ステップ 205で表示装置に商品有り状態用表示を表示する。  [0041] In step 204, a product presence state display is generated based on the read product information, and in step 205, the product presence state display is displayed on the display device.
[0042] 図 5の (A)は、商品有り状態用表示の例であり、表示面 41に、商品名、価格、商品 説明、売れ筋ランキングなどを表示する。第 1実施例では、更に商品の画像 (イメージ )が表示される。これにより、商品を手にとって見た後商品棚に戻す時に、誤った商品 棚に戻すことがなくなる。また、イメージを表示することにより、客に表示内容がどの商 品に対応する力を明瞭に示すこともできる。  FIG. 5A is an example of a display for a product presence state, and the product name, price, product description, best seller ranking, etc. are displayed on the display surface 41. In the first embodiment, a product image is also displayed. This prevents the product from being returned to the wrong product shelf when the product is viewed by hand and then returned to the product shelf. In addition, by displaying an image, it is possible to clearly show the customer the ability of the displayed content to correspond to which product.
[0043] 売れ筋ランキングは、店舗全体を制御するシステム力も得て、 POSDB23に記憶し たデータ力 生成される。  [0043] The selling power ranking is also generated by the data power stored in the POSDB 23 by obtaining the system power to control the entire store.
[0044] 一方、ステップ 206では、タイマーを動作させて所定時間、例えば、数分が経過す るまで待機し、ステップ 207で再びタグ信号が検出されるかを判定する。タグ信号が 検出される場合にはステップ 203に進み、タグ信号が検出されない場合にはステップ 208に進む。これにより、客が最後の 1個の商品を手にとって再び商品棚に戻す場合 、商品あり状態用表示が維持される。 On the other hand, in step 206, the timer is operated to wait until a predetermined time, for example, several minutes elapses, and in step 207, it is determined whether the tag signal is detected again. Tag signal If detected, the process proceeds to step 203, and if no tag signal is detected, the process proceeds to step 208. As a result, when the customer picks up the last product and returns it to the product shelf again, the product status display is maintained.
[0045] ステップ 208では、タグ信号が検出されない状態になって力 所定時間が経過する ので、商品棚には商品が置かれていないと考えられるので、ステップ 201で確認した 位置番号の棚に置かれる商品の在庫、在庫が無い場合には入荷予定、商品情報な どを、データベースから読み取る。  [0045] In step 208, since the tag signal is not detected and a predetermined time elapses, it is considered that no product is placed on the product shelf, so the product is placed on the shelf of the position number confirmed in step 201. The inventory of the product to be used, and when there is no inventory, the arrival schedule, product information, etc. are read from the database.
[0046] ステップ 209では、読み取った在庫、入荷予定、商品情報に基づ 、て商品無し状 態用表示を生成し、ステップ 210で表示装置に商品無し状態用表示を表示する。  In step 209, based on the read inventory, arrival schedule, and product information, a product no-goods state display is generated. In step 210, the product no-goods state display is displayed on the display device.
[0047] 図 5の(B)は、商品無し状態用表示の例であり、表示面 41に、商品名、価格、商品 説明、売れ筋ランキング、商品の画像 (イメージ) 42などと共に、「品切れ中」及び入 荷予定日を表示する。これにより、客は品切れ中の商品が何時入荷し、どのような商 品であるかを明瞭に把握できるので、入荷するまで待って購入するかどうかを容易に 判断できる。  [0047] (B) in FIG. 5 is an example of the display for the state of no product. The display screen 41 is displayed with a product name, price, product description, hot selling ranking, product image (image) 42, etc. "And the estimated date of arrival. As a result, the customer can clearly understand when the out-of-stock item is received and what kind of product it is, so it is easy to determine whether to wait for the item to arrive before purchasing.
[0048] 以下、制御対象の商品棚を変更して上記処理を繰り返し、すべての商品棚につい て上記の処理を行う。  [0048] Hereinafter, the above processing is repeated by changing the control target product shelf, and the above processing is performed for all product shelves.
[0049] 第 1実施例では、 1つの商品棚には 1種類の商品が置かれるという制限が設けられ ていたが、第 2実施例では 1つの商品棚に複数種類の商品が置かれる場合に対応 する。第 2実施例の表示システムは、第 1実施例と同様の構成を有し、タグリーダ 11 は、異なるタグ信号を出力する RFIDタグの信号を検出することが可能であり、タグ解 析部 12は、タグリーダが検出した信号を解析して、複数種類の商品の異なるタグ情 報信号を分離して抽出する点のみが異なる。  [0049] In the first embodiment, there is a restriction that one kind of product can be placed on one commodity shelf, but in the second embodiment, when a plurality of kinds of goods are placed on one commodity shelf. Correspond. The display system of the second embodiment has the same configuration as that of the first embodiment, the tag reader 11 can detect the signal of the RFID tag that outputs a different tag signal, and the tag analyzer 12 The only difference is that the signal detected by the tag reader is analyzed to separate and extract different tag information signals for multiple types of products.
[0050] 図 6は、第 2実施例のシステムの動作を示すフローチャートである。ステップ 301で は、対象となる商品棚の位置番号を確認する。  FIG. 6 is a flowchart showing the operation of the system of the second embodiment. In step 301, the position number of the target product shelf is confirmed.
[0051] ステップ 302では、タグリーダ 11が何種類の商品のタグ信号を検出しているかを判 定する。その商品棚に置かれる商品が N種類であるとすると、 N種類のタグ信号を検 出する場合にはステップ 302に進み、 1種類から N— 1種類のタグ信号を検出する場 合にはステップ 306に進み、 1つもタグ信号を検出しない場合には、ステップ 310に 進む。 [0051] In step 302, it is determined how many types of product tag signals are detected by the tag reader 11. Assuming that there are N types of products placed on the product shelf, if N types of tag signals are detected, go to step 302. If N types of tag signals are detected from one type, step 1 is required. Proceed to 306, and if no tag signal is detected, go to step 310. move on.
[0052] ステップ 303では、検出した複数種類の商品のタグ信号を解析して商品種別番号、 固体識別番号などのそれぞれのタグ情報を得て、それに対応する複数の商品情報 をデータベースから読み取る。  [0052] In step 303, tag signals of a plurality of types of detected products are analyzed to obtain respective tag information such as a product type number and a solid identification number, and a plurality of corresponding product information is read from the database.
[0053] ステップ 304では、読み取った複数の商品情報に基づいて複数商品の有り状態用 表示を生成し、ステップ 305で表示装置に複数商品の有り状態用表示を表示する。 [0053] In step 304, a display for the presence of multiple products is generated based on the read product information, and in step 305, a display for the presence of multiple products is displayed on the display device.
[0054] ステップ 306では、存在するタグ信号を解析して商品種別番号、固体識別番号など のそれぞれのタグ情報を得て、それに対応する複数の商品情報をデータベースから 読み取る。  In step 306, the existing tag signal is analyzed to obtain each tag information such as a product type number and a solid identification number, and a plurality of product information corresponding to the tag information is read from the database.

[0056] ステップ 308では、商品棚にある商品についての商品有り状態用表示と、商品棚に ない商品についての商品無し状態用表示を生成し、ステップ 309で表示装置に商品 有り状態用表示及び商品無し状態用表示を表示する。  [0056] In step 308, a product presence state display for the product in the product shelf and a product absence state display for the product not in the product shelf are generated. In step 309, the product presence state display and the product are displayed on the display device. Displays the display for the absence state.
[0057] 図 7は、ステップ 309で表示される商品有り状態用表示及び商品無し状態用表示 の例であり、表示面 51に、各商品の商品名、価格、商品説明、売れ筋ランキング、商 品の画像 (イメージ) 52、 53、 54などを表示し、商品棚にない商品については「品切 れ中」及び入荷予定日を表示する。図 7では、 B商品が品切れであり、 B商品のィメー ジ 53は、「品切れ中」であることが分力るように、 A商品及び B商品のイメージ 42、 54 と区別して表示されることが望ま 、。  [0057] FIG. 7 is an example of the product presence state display and the product absence state display displayed in step 309. On the display surface 51, the product name, price, product description, best seller ranking, and product of each product are displayed. Images 52, 53, 54, etc. are displayed. For products not on the product shelf, “out of stock” and the expected arrival date are displayed. In Figure 7, product B is out of stock, and image 53 of product B is displayed separately from images 42 and 54 of product A and product B so that it can be divided into “out of stock”. Is desired.
[0058] ステップ 310では、ステップ 301で確認した位置番号の商品棚に置かれるすべての 商品の在庫、在庫が無い場合には入荷予定、商品情報などを、データベース力 読 み取る。  [0058] In step 310, the database is read for the stock of all the products placed on the product shelf of the position number confirmed in step 301, the arrival schedule when there is no stock, product information, and the like.
[0059] ステップ 311では、読み取った在庫、入荷予定、商品情報に基づいてすべての商 品についての商品無し状態用表示を生成し、ステップ 312で表示装置に商品無し状 態用表示を表示する。  In step 311, a display for no product status is generated for all products based on the read inventory, arrival schedule, and product information. In step 312, a display for no product status is displayed on the display device.
[0060] なお、第 2実施例においても、第 1実施例と同様に、各種類について最後の 1個の 商品が手にとられて再び商品棚に戻された場合にも商品有り状態用表示を維持する ために、タイマー処理を行うようにすることが望ま 、。 [0060] In the second embodiment, as in the first embodiment, the last one for each type is used. It is desirable to perform timer processing in order to maintain the display for the product presence state even when the product is picked up and returned to the product shelf.
[0061] 本発明の第 3実施例の表示システムは、本発明を図書館などの書架、特に雑誌棚 における表示に適用した例である。図 8は、本発明を適用した第 3実施例の図書館の 書架 (雑誌棚)の外観を示す図である。第 3実施例の表示システムの基本的な構成は 、前述の基本構成及び第 1実施例の構成と同じであるが、第 3実施例では、図 8の (A )に示すように、棚 61 A— 61Dのそれぞれの書籍が置かれる部分に電子ペーパーに よる表示装置 62A— 62Dが設けられている。従って書籍 63を棚 61に置くと、図 8の( B)のようになり、表示装置 62A—62Dの上側の分は見える力 下側の部分は書籍に より見えなくなる。 RFIDタグは各書籍に付けられており、タグリーダは電子ペーパー の下に配置されている。  [0061] The display system according to the third embodiment of the present invention is an example in which the present invention is applied to display in a bookshelf such as a library, especially a magazine shelf. FIG. 8 is a view showing the appearance of a library shelf (magazine shelf) of the third embodiment to which the present invention is applied. The basic configuration of the display system of the third embodiment is the same as the basic configuration described above and the configuration of the first embodiment. However, in the third embodiment, as shown in FIG. A display device 62A-62D by electronic paper is provided in the part where each book of A-61D is placed. Therefore, when the book 63 is placed on the shelf 61, it becomes as shown in FIG. 8B, and the upper part of the display devices 62A-62D is visible. The lower part is not visible by the book. An RFID tag is attached to each book, and a tag reader is placed under the electronic paper.
[0062] 図 9は、第 3実施例のシステムの動作を示すフローチャートである。第 3実施例でも 、複数の棚が 1つのサーバー部で時分割制御されるので、ステップ 401では、処理の 対象となる棚の位置番号を確認する。  FIG. 9 is a flowchart showing the operation of the system of the third embodiment. Also in the third embodiment, since a plurality of shelves are time-division controlled by one server unit, in step 401, the position numbers of the shelves to be processed are confirmed.
[0063] ステップ 402では、タグリーダがタグ信号を検出しているかを判定する。タグ信号が 検出されている時には、対応する棚に書籍が置かれていることを意味し、タグ信号が 検出されていない時には、対応する棚に書籍が置かれていないことを意味する。タグ 信号が検出された場合にはステップ 403に進み、タグ信号が検出されない場合には ステップ 406に進む。  [0063] In step 402, it is determined whether the tag reader detects a tag signal. When the tag signal is detected, it means that the book is placed on the corresponding shelf, and when the tag signal is not detected, it means that the book is not placed on the corresponding shelf. If the tag signal is detected, the process proceeds to step 403. If the tag signal is not detected, the process proceeds to step 406.
[0064] ステップ 403では、検出したタグ信号を解析して書籍番号、固体識別番号などのタ グ情報を得て、その棚に置かれる書籍の書籍番号と一致するかを判定する。番号の 不一致は、棚に置かれる書籍と異なる書籍が棚に置かれることを意味する。番号が 一致する場合にはステップ 404に進み、番号が一致しない時にはステップ 409に進 む。  [0064] In step 403, the detected tag signal is analyzed to obtain tag information such as a book number and a solid identification number, and it is determined whether or not it matches the book number of the book placed on the shelf. A number mismatch means that a book that is different from the book placed on the shelf is placed on the shelf. If the numbers match, go to step 404. If the numbers do not match, go to step 409.
[0065] ステップ 404では、タグ情報に対応する書籍情報を読み取り、ステップ 405で書籍 情報を表示する。図 10の (A)は、書籍情報の表示例である。図 10に示すように、棚 61の表示装置(電子ペーパー) 61の部分には書籍 63が置かれるので、表示装置 6 1の上側の部分しか見ることはできないので、この部分に書籍の解説などを表示する [0066] ステップ 406では、制御対象の棚に書籍が置かれていないので、棚の位置番号に 対応する書籍、すなわち棚に置かれる書籍の状況及び書籍情報を読み取る。書籍 の状況は、書籍が貸し出しされている力、貸し出しされている場合返却予定日はいつ 力などの情報である。 In step 404, the book information corresponding to the tag information is read, and in step 405, the book information is displayed. (A) in FIG. 10 is a display example of book information. As shown in Fig. 10, since the book 63 is placed on the display device (electronic paper) 61 of the shelf 61, only the upper part of the display device 61 can be seen. Display [0066] In step 406, since no book is placed on the shelf to be controlled, the book corresponding to the position number of the shelf, that is, the status of the book placed on the shelf and the book information are read. The status of a book is information such as the power at which the book is lent and the power when the book is rented.
[0067] ステップ 407では、書籍の状況及び書籍情報に基づ 、て書籍が無 、状態に対応 する無し状態用表示を生成し、ステップ 408で表示する。  [0067] In step 407, based on the status of the book and the book information, there is no book and a no-status display corresponding to the status is generated and displayed in step 408.
[0068] 図 10の(B)は、無し状態用表示の表示例である。図示のように、表示装置 62の画 面はすべて見える状態であり、書籍が貸し出し中であれば、「貸し出し中」及び返却 予定日を表示し、更に書籍の解説や書籍のイメージ 65を表示する。また、棚に書籍 はないが、貸し出し中でもない場合には、閲覧されていると考えられるので、「貸し出 し中」の代わりに「閲覧中」を表示する。イメージ 65が表示されるので、閲覧後書籍を 棚に戻す場合にも戻す棚を間違えることが無くなる。  FIG. 10B shows a display example of the display for the absence state. As shown in the figure, all the screens of the display device 62 are visible, and if the book is being lent out, “Lending” and the scheduled return date are displayed, and further, a description of the book and an image 65 of the book are displayed. . If there is no book on the shelf but it is not rented, it is considered that it is being browsed, so “browsing” is displayed instead of “lending”. Since the image 65 is displayed, the shelf to be returned is not mistaken when returning the book to the shelf after browsing.
[0069] ステップ 403で番号が一致しない場合には、ステップ 409に進んで、不一致の警告 を表示装置に表示する。ステップ 403及び 409の処理は、書籍が棚に近づいた状態 で迅速に行うことが望ましぐ警告を表示することにより、利用者が誤って書籍を置こう としたことに気付くので、置く棚を確認する動作を促すことになる。警告は、書籍が置 かれても見える部分に表示し、表示を点滅させるなどしてより注意を引くようにするこ とが望ましい。  [0069] If the numbers do not match in step 403, the process proceeds to step 409 to display a mismatch warning on the display device. The processing in steps 403 and 409 shows that the user has mistakenly attempted to place a book by displaying a warning that is desired to be done quickly with the book approaching the shelf. You will be prompted to confirm. It is desirable to display the warning in a visible part even if the book is placed and draw more attention by blinking the display.
[0070] ステップ 409の後には、ステップ 402に戻る。  [0070] After step 409, the process returns to step 402.
[0071] 図 11は、本発明を適用した第 4実施例の商品棚の外観を示す図である。第 4実施 例の表示システムの基本的な構成は、前述の基本構成及び第 1実施例の構成と同じ であるが、第 4実施例では、商品棚 70の下の全面に亘つて電子ペーパーを設ける。 商品棚 70は、複数の領域 71A、 71B、…に分割され、電子ペーパーは各領域ごと に表示を行うことが可能で、電子ペーパーの下には各領域ごとにタグリーダが設けら れており、商品棚に置かれた商品 72のタグ情報が検出できると共に、商品 72がどの 領域内に置かれて 、るかが検出できるようになって!/、る。  FIG. 11 is a view showing the appearance of the product shelf of the fourth embodiment to which the present invention is applied. The basic configuration of the display system of the fourth embodiment is the same as the basic configuration described above and the configuration of the first embodiment, but in the fourth embodiment, electronic paper is placed over the entire surface under the product shelf 70. Provide. The product shelf 70 is divided into a plurality of areas 71A, 71B,..., Electronic paper can be displayed for each area, and a tag reader is provided for each area under the electronic paper. The tag information of the product 72 placed on the product shelf can be detected, and the region in which the product 72 is placed can be detected! /.
[0072] 図 12は、第 4実施例のシステムの動作を示すフローチャートである。各領域に対応 して設けられたタグリーダの検出状態が変化したかを検出する。状態変化の検出に ついては、後述する。検出状態が変化するまで、状態変化の検出を繰り返すが、検 出は所定時間間隔で行えばよい。検出状態が変化したらステップ 502に進み、変化 した領域を特定する。 FIG. 12 is a flowchart showing the operation of the system of the fourth embodiment. Corresponding to each area Then, it is detected whether the detection state of the tag reader provided is changed. The detection of the state change will be described later. The detection of the state change is repeated until the detection state changes, but the detection may be performed at predetermined time intervals. If the detection state changes, the process proceeds to step 502 to identify the changed area.
[0073] ステップ 503では、変化した領域のタグリーダがタグ信号を検出して 、るかを判定し 、タグ信号を検出している時にはステップ 504に進み、タグ信号を検出していない時 にはステップ 507に進む。  [0073] In step 503, it is determined whether the tag reader in the changed area detects the tag signal. If the tag signal is detected, the process proceeds to step 504. If the tag signal is not detected, step 503 is performed. Proceed to 507.
[0074] タグ信号を検出する場合には、商品棚のその領域に商品が置かれており、表示装 置のその領域に表示を行っても上に置かれた商品で表示が見えないので、ステップ 504で、その領域の隣接領域に商品の置かれていない、すなわちタグ信号が検出さ れない領域 (空き領域)があるかを判定する。空き領域が無い場合には、ステップ 50 1に戻る。  [0074] When a tag signal is detected, the product is placed in that area of the product shelf, and even if the display is made in that area of the display device, the display cannot be seen with the product placed above. In step 504, it is determined whether or not there is an area (free area) in which no product is placed, that is, a tag signal is not detected in an adjacent area. If there is no free space, return to Step 501.
[0075] 空き領域がある場合には、ステップ 505に進み、前記の領域に置かれている商品の タグ情報に対応する商品情報を読み取り、ステップ 506で、図 11の (A)に示すように 、商品 72の情報を隣接する電子ペーパーの空き領域の部分 73に表示する。  [0075] If there is an empty area, the process proceeds to step 505, where the product information corresponding to the tag information of the product placed in the area is read, and in step 506, as shown in FIG. The information of the product 72 is displayed in the empty area portion 73 of the adjacent electronic paper.
[0076] 一方、ステップ 507では、タグ信号が検出されないので、商品棚のその領域には商 品が無いと判断して、図 11の(B)に示すように、その領域に置かれるべき商品の情 報、例えば、商品名、価格、イメージなどを表示する。更に、「品切れ中」の表示や入 荷予定日を表示してもよい。もちろん、タグ信号が検出されない場合でも、すでに空 き領域として表示に使用されている時には、このような表示は行わない。隣接した領 域に置かれた商品の商品情報を表示する力、置かれて!/、な 、がその領域に置かれ るべき商品の商品情報を表示するかは、優先度を設定して適宜選択できるようにする  On the other hand, in step 507, since no tag signal is detected, it is determined that there is no product in that area of the product shelf, and as shown in FIG. 11B, the product to be placed in that area. Information, such as product name, price, and image. Furthermore, “out of stock” display or scheduled arrival date may be displayed. Of course, even when the tag signal is not detected, such display is not performed when the tag signal is already used for display as an empty area. The power to display the product information of the product placed in the adjacent area, whether to display the product information of the product that should be placed in that area, is set according to the priority. Allow selection
[0077] 第 4実施例では、各領域内に配置されるタグリーダは、各領域内に配置される RFI Dタグのタグ信号を検出すると共に、商品棚力もある高さまでの RFIDタグのタグ信号 も検出する。従って、客が商品を手にとって商品棚力も持ち上げるとタグ信号は検出 されなくなる。購入するためにそのまま商品をレジに持っていった場合には、販売さ れたことが全体を管理するシステムにより検出され、 PODDBが更新される。しかし、 客が手にとった商品を購入せずに再び商品棚に戻す場合もあり、この場合にはタグリ ーダが再びタグ信号を検出することになる。 [0077] In the fourth embodiment, the tag reader arranged in each area detects the tag signal of the RFI D tag arranged in each area, and also has the tag signal of the RFID tag up to a certain height with the product shelf power. To detect. Therefore, if the customer picks up the product and raises the product shelf power, the tag signal is not detected. If the product is taken directly to the cash register for purchase, it is detected by the system that manages the whole and the PODDB is updated. But, The customer may return the product to the product shelf again without purchasing it, and in this case, the tag reader will detect the tag signal again.
[0078] 客が手にとる回数が多い商品はそれだけ注目されていると考えられる。これまでレ ジにおいて実際に販売された商品については管理され、その販売情報は在庫状態 や仕入れに利用されていた。しかし、購入には至らないが客が興味を示した商品に 関する情報は何ら考慮されていな力つた。第 4実施例では、上記のようなタグ信号の 状態変化の回数を計数にて、客が注目して興味を示した商品に関する情報を注目 度として収集する。  [0078] It is considered that a product that has been frequently picked up by customers is attracting much attention. Until now, the products actually sold in the region were managed, and the sales information was used for inventory status and purchase. However, the information about the products that the customer showed interests that did not result in purchase was not taken into consideration. In the fourth embodiment, the number of changes in the state of the tag signal as described above is counted, and information relating to products that the customer has shown an interest in is collected as the degree of attention.
[0079] 図 13は、ステップ 501の状態変化の検出の詳細を示すフローチャートである。ステ ップ 601では、タグ信号を読み取り、ステップ 602でタグ信号の有無を判定し、タグ信 号があればステップ 603でフラグ Fを 1に設定し、タグ信号がなければステップ 604で フラグ Fを 0に設定する。以上の処理は初期化である。必要であれば、計数値 (カウン ト値)のレジスタもリセットする。  FIG. 13 is a flowchart showing details of the state change detection in step 501. In step 601, the tag signal is read. In step 602, the presence or absence of the tag signal is determined. If there is a tag signal, flag F is set to 1 in step 603, and if there is no tag signal, flag F is set in step 604. Set to 0. The above processing is initialization. If necessary, reset the count (count) register.
[0080] ステップ 605では、タグ信号を読み取り、ステップ 606でタグ信号の有無を判定し、 タグ信号があればステップ 607で一時フラグ Fiを 1に設定し、タグ信号がなければス テツプ 608で一時フラグ Fiを 0に設定する。そして、ステップ 609で、フラグ Fと一時フ ラグ Fiを比較し、一致すれば変化していないので、ステップ 605に戻る。一致しない 時にはステップ 610に進んで、フラグ Fに一時フラグ Fiの値を代入した後、ステップ 6 11でカウント値を増加させる。このカウント値は、客が商品を手にとってそのままレジ で購入した時には 1だけ増加するが、客が商品を手にとって戻した場合には 2変化す る。購入されたことはレジの情報を収集する POSシステムにより判明するので、その 分を差し引けば、客が商品を手にとって戻した回数を求めることができる。  [0080] In step 605, the tag signal is read. In step 606, the presence or absence of the tag signal is determined. If there is a tag signal, the temporary flag Fi is set to 1 in step 607, and if there is no tag signal, temporary processing is performed in step 608. Set the flag Fi to 0. Then, in step 609, the flag F and the temporary flag Fi are compared. If they match, there is no change, and the process returns to step 605. If they do not match, the routine proceeds to step 610, the value of the temporary flag Fi is substituted for the flag F, and then the count value is increased at step 611. This count increases by 1 when the customer purchases the product as it is, and changes by 2 when the customer returns the product. The purchase is determined by the POS system that collects cash register information, and by subtracting that amount, the number of times the customer has returned the product can be obtained.
[0081] 図 13のようにして求めた回数を注目度ランキングとして、売れ筋ランキングと一緒に 表示する。このような注目度ランキングの表示は、第 4実施例だけでなぐ第 1から第 3 実施例でも同様に行える。特に図書館の場合、貸し出しされない書籍でも、よく手に とられた、すなわちよく読まれた書籍を特定することが可能になる。  [0081] The number of times obtained in the manner shown in Fig. 13 is displayed together with the hot selling ranking as the attention ranking. Such attention ranking display can be performed in the same manner in the first to third embodiments as well as in the fourth embodiment. In particular, in the case of libraries, even books that are not lent out can be identified as books that are often picked up, that is, read well.
[0082] 第 4実施例では、商品棚を領域分けして、各領域に対応させてタグリーダを設けた [0082] In the fourth embodiment, the product shelf is divided into regions, and tag readers are provided corresponding to the regions.
1S 対象となる物品が棚から取り上げられたことが検出できれば、注目度を検出する ことが可能である。また、タグリーダがタグ信号の個数を検出できる場合には、棚に複 数の商品がある場合でも、検出するタグ信号の個数の変化を検出することにより、注 目度を検出することが可能である。 1S If it can be detected that the target item has been picked up from the shelf, the attention level is detected. It is possible. Also, if the tag reader can detect the number of tag signals, even if there are multiple products on the shelf, it is possible to detect the degree of attention by detecting the change in the number of tag signals to be detected. is there.
[0083] 本発明の第 5実施例の表示システムは、本発明を銀行や役所などにある記帳台に おける表示に適用した例である。図 14は、本発明を適用した第 5実施例の銀行の記 帳台の外観を示す図である。第 5実施例の表示システムの基本的な構成は、前述の 基本構成及び第 3実施例の構成と同じであるが、第 5実施例では、図 14の (A)に示 すように、記帳台 80の記帳を行う部分に電子ペーパーによる表示装置 82が設けら れている。参照番号 81は、振込み用紙、税金'公共領域の支払い用紙、新規講座開 設用紙などの各種の用紙が置かれる部分である。従って用紙を記帳台に置くと、電 子ペーパー 82の一部が見えなくなる。 RFIDタグは各用紙に付けられている。タグリ ーダは、電子ペーパー 82の下に、複数個配置されており、電子ペーパーのどの部 分に用紙が置かれたかが検出できる。  [0083] The display system according to the fifth embodiment of the present invention is an example in which the present invention is applied to a display on a book stand in a bank or a government office. FIG. 14 is a diagram showing the appearance of a bank book table of the fifth embodiment to which the present invention is applied. The basic configuration of the display system of the fifth embodiment is the same as the basic configuration described above and the configuration of the third embodiment, but in the fifth embodiment, as shown in FIG. A display device 82 using electronic paper is provided in the part where the table 80 is to be booked. Reference numeral 81 is a portion where various papers such as a transfer paper, a tax 'public area payment paper, and a new course opening paper are placed. Therefore, when the paper is placed on the bookkeeping board, a part of the electronic paper 82 becomes invisible. An RFID tag is attached to each sheet. A plurality of tag readers are arranged under the electronic paper 82, and it is possible to detect to which part of the electronic paper the paper is placed.
[0084] 図 15は、第 5実施例のシステムの動作を示すフローチャートである。  FIG. 15 is a flowchart showing the operation of the system of the fifth embodiment.
[0085] ステップ 701では、タグリーダがタグ信号を検出しているかを判定する。タグ信号が 検出されていない時には、ステップ 702に進み、図 16の(C)に示すような記帳に関 する一般的な案内を表示する。参照番号 85は税金'公共領域の支払い用紙の記入 例を、参照番号 86は新規講座開設用紙の記入例を示す。  In step 701, it is determined whether the tag reader detects a tag signal. When the tag signal is not detected, the process proceeds to Step 702, and general guidance about the book entry as shown in FIG. 16 (C) is displayed. Reference number 85 is an example of a tax payment form for public areas, and reference number 86 is an example of a new course opening form.
[0086] ステップ 701でタグ信号が検出されている時には、ステップ 703に進み、タグ情報を 解析して、タグ情報で示される用紙に対応する表示を行う。図 16の (A)は、その場合 の表示例であり、電子ペーパー 82の一部に用紙 83が置かれるので、それ以外の部 分にその用紙 83に対応した記入例 84を表示する。  When a tag signal is detected in step 701, the process proceeds to step 703, where the tag information is analyzed and a display corresponding to the paper indicated by the tag information is performed. FIG. 16A shows a display example in that case. Since the paper 83 is placed on a part of the electronic paper 82, an entry example 84 corresponding to the paper 83 is displayed on the other part.
[0087] ステップ 703でタイマーをセットして、ステップ 705で再びタグ信号が検出されてい るかを判定する。タグ信号が検出されない時には、記帳が終了して用紙を記帳台か ら持ち上げたと考えられるので、ステップ 707に進み、図 16の(B)に示すような記帳 後に行うべき処理を案内する表示を行う。図 16の(B)で、参照番号 83'は、記帳台 から持ち上げられた用紙を示す。図 16の (B)の表示は、用紙を記帳台から持ち上げ た直後に行う必要があるので、タグリーダは、用紙が記帳台から少し持ち上げられる とタグ信号を検出しな 、ように設定することが望ま 、。 [0087] In step 703, a timer is set, and in step 705, it is determined whether a tag signal is detected again. When the tag signal is not detected, it is considered that the book has been finished and the paper has been lifted from the book stand. Therefore, the process proceeds to step 707, and a display for guiding the processing to be performed after the book entry as shown in FIG. . In FIG. 16B, reference numeral 83 ′ indicates the paper lifted from the book table. The display in (B) of Fig. 16 must be performed immediately after the paper is lifted from the bookkeeping board, so the tag reader can lift the paper slightly from the bookkeeping board. It is desirable to set so that no tag signal is detected.
[0088] ステップ 705でタグ信号が検出されていると判定された時には、ステップ 706に進 み、タイマーでセットされた時間が経過したかを判定し、経過するまでステップ 705と 706を繰り返す。そしてセットした時間が経過すると、用紙が記帳台の上に放置され た状態になっていると考えられるので、ステップ 702に進んで一般的な案内を表示す るようにする。 If it is determined in step 705 that the tag signal has been detected, the process proceeds to step 706, where it is determined whether the time set by the timer has elapsed, and steps 705 and 706 are repeated until it has elapsed. When the set time has elapsed, it is considered that the paper has been left on the bookkeeping table, so the routine proceeds to step 702 to display general guidance.
