Description

  The present invention relates to an electronic shelf label system including a plurality of electronic shelf labels that are arranged corresponding to products and display product data relating to the corresponding products.

  Generally, in stores such as supermarkets and convenience stores, the selling prices of products in the store are managed centrally by a product master stored in a POS system or the like. On the other hand, the selling price is often transmitted to customers (consumers) using paper medium shelf labels placed at the positions of the products. When such a paper medium shelf label is adopted, the management of the shelf label must be relied upon manually, and thus human error such as a mistake in selling price tends to occur. For this reason, there is a possibility that an incorrect selling price different from the selling price at the time of settlement by the register of the POS system is transmitted to the customer.

  In order to solve such a problem, an electronic shelf label system (ESL system / Electronic Shelf Label System) has been put into practical use in recent years. In the electronic shelf label system, portable electronic shelf labels that display product data such as selling prices are arranged corresponding to each product. Then, a communication signal including a selling price based on the product master is transmitted from the distribution side device to each electronic shelf label, and the selling price is displayed on each electronic shelf label. Thus, the correct selling price that matches the selling price at the time of settlement is displayed on the electronic shelf label, and the correct selling price is transmitted to the customer (see, for example, Patent Documents 1 and 2).

Thereby, the product and the electronic shelf label 5 are associated with each other in a one-to-one relationship (linked). By using this “device code”, product data relating to a product is transmitted to the electronic shelf label 5 corresponding to the product.

<2-3. Electronic shelf label>
Next, the electronic shelf label 5 will be described. FIG. 5 is a diagram showing a configuration of the electronic shelf label 5. As shown in the figure, on the front surface of the electronic shelf label 5, a display 51 for displaying product data such as the selling price of the corresponding product, and a communication unit 54 including a receiving unit 52 and a transmitting unit 53 are arranged. Yes. The receiving unit 52 receives a radio signal such as a data signal or a remote control signal, and the transmitting unit 53 transmits a radio signal such as a confirmation signal.

  The display 51 includes a dot matrix rectangular liquid crystal screen composed of a plurality of pixels arranged in an orthogonal two-dimensional array. The display 51 displays the image data relating to the entire screen (image data consisting of a plurality of pixels having the same arrangement as the constituent pixels of the screen: hereinafter referred to as “whole image”), thereby indicating the selling price of the product. Not only numerical values but also various kinds of information such as characters, symbols and figures can be displayed.

  In addition, the electronic shelf label 5 includes a control unit 55 configured by an integrated circuit for controlling the operation of the apparatus. The control unit 55 is provided with a memory 56 for storing various information such as an entire image to be displayed on the display 51 and a device code of the own device.

  In the electronic shelf label 5 of this embodiment, the longitudinal direction of the screen of the display 51 is arranged along the horizontal direction (hereinafter referred to as “horizontal arrangement”) and the arrangement along the vertical direction (hereinafter referred to as “vertical arrangement”). ), The characters displayed on the display 51 can be arranged in a normal direction as a language. In order to perform such display, the memory 56 of the electronic shelf label 5 stores the entire image for horizontal arrangement to be displayed in the horizontal arrangement and the entire image for vertical arrangement to be displayed in the vertical arrangement. Both are memorized.

  FIG. 6 shows an example of the entire image 81 for horizontal arrangement, and FIG. 7 shows an example of the entire image 82 for vertical arrangement. As shown in these figures, in both of the whole images 81 and 82, an eye catch 8a for attracting customers, a selling price 8b, a product name 8c, and a product code (exactly its barcode) 8d are product data. Included as However, the arrangement direction of the product data in the image differs by 90 degrees between the horizontal arrangement and the vertical arrangement. More specifically, if the vertical direction when a single character is arranged in a direction that can be recognized as a language is defined as “character direction”, the “character direction” of the horizontal image 81 (FIG. 6) is the image. On the other hand, the “character direction” of the vertically arranged whole image 82 (FIG. 7) is along the longitudinal direction of the image.

  Therefore, when the entire image 81 for horizontal arrangement (FIG. 6) is displayed on the display 51 in the horizontal arrangement as shown in FIG. 8, the “character direction” is along the vertical direction, while on the other hand, as shown in FIG. When the entire image 82 for vertical arrangement (FIG. 7) is displayed on the display 51 at the time of arrangement, the “character direction” is along the vertical direction. As a result, the characters displayed on the display 51 can be arranged in a normal direction as a language in both the horizontal arrangement and the vertical arrangement.

  Whether the display 51 displays the entire image for horizontal arrangement or for horizontal arrangement is determined based on the “display mode”. The “display mode” includes “horizontal mode” and “vertical mode”. In the “horizontal mode”, the entire image 81 for horizontal arrangement is displayed, and in the “vertical mode”, the entire image 82 for vertical arrangement is displayed. Is displayed. Therefore, when the “display mode” is changed between “horizontal mode” and “vertical mode”, the entire image displayed on the display 51 is changed accordingly for horizontal arrangement and vertical arrangement, The character displayed on the display 51 is rotated 90 degrees on the screen.

<2-4. Rotating member>
Further, in the electronic shelf label system 1 of the present embodiment, the rear side (product shelf) of the electronic shelf label 5 is arranged so that the arrangement direction of the electronic shelf label 5 can be easily changed between the horizontal arrangement and the vertical arrangement. A rotating member is provided on the side attached to 60.

  10 and 11 are exploded perspective views showing the configuration of the rotating member 90. FIG. As shown in these drawings, the rotating member 90 includes a shelf label side member 91 fixed to the electronic shelf label 5 side, and a disk-shaped fixed side member 92 fixed to the product shelf 60 side. The shelf label side member 91 is a disk-shaped member, and is attached to the back side of the electronic shelf label 5 so that the disk surface is parallel to the screen of the display 51. On the other hand, the fixed side member 92 is also a disk-shaped member, and is attached to the frame 62 of the product shelf 60 so that the disk surface is along the vertical direction.

  A rotating shaft 912 is formed at the disk center 911 of the shelf label side member 91. The rotation shaft 912 is fitted into the shaft hole 922 in the disk center 921 of the fixed side member 92. Thereby, the shelf label side member 91 is rotatable with respect to the fixed side member 92 around the rotation shaft 912. That is, the screen of the display 51 of the electronic shelf label 5 can be rotated with respect to the product shelf 60 within a plane including the vertical direction (YZ plane).

  In addition, one protruding portion 913 is formed on the disk surface of the shelf label side member 91 on the side facing the fixed side member 92 (−X side). The protrusion 913 is formed at a position extending from the disc center 911 along the longitudinal direction of the screen of the display 51 (the longitudinal direction of the two arrangement directions of the constituent pixels of the screen).

  On the other hand, two holding holes 923 and 924 for fitting with the protrusions 913 are formed on the disk surface of the fixed side member 92 facing the shelf label side member 91 (+ X side). One holding hole 923 is formed at a position extending substantially horizontally (−Y side) from the disk center 921, and the other holding hole 924 is formed at a position extending substantially vertically above (+ Z side) from the disk center 921. . Therefore, when the protruding portion 913 of the shelf label side member 91 is fitted into the holding hole 923, the longitudinal direction of the screen of the display 51 is fixed along the substantially horizontal direction, and the electronic shelf label 5 is arranged horizontally (see FIG. 10). In addition, when fitted in the holding hole 924, the longitudinal direction of the screen of the display 51 is fixed along the substantially vertical direction, and the electronic shelf label 5 is arranged vertically (see FIG. 11).

  When the arrangement direction of the electronic shelf label 5 is actually changed, first, the electronic shelf label 5 is pulled out to the front side (+ X side) until the protruding portion 913 is removed from one holding hole (for example, the holding hole 923). And after rotating the electronic shelf label 5 centering on the rotating shaft 912, it pushes into the back side (-X side), and the projection part 913 is engage | inserted in the other holding hole (for example, holding hole 924). Thereby, the arrangement direction of the electronic shelf label 5 can be easily changed between the horizontal arrangement and the vertical arrangement. Such a rotating member 90 may be configured as a part of a holder for attaching the electronic shelf label 5 to the commodity shelf 60, or may be formed in a part of the housing of the electronic shelf label 5.

<3. Operation of the electronic shelf label system>
Next, the operation of the electronic shelf label system 1 will be described.

<3-1. Basic operation>
First, the basic operation of the electronic shelf label system 1 will be briefly described. The basic operation of the electronic shelf label system 1 is to transmit the data signal from the distribution side device 40 to the electronic shelf label 5 and distribute the product data to be displayed on the screen of the display 51. Distribution of such product data is performed when the system is started up, when the selling price of the product is updated, and the like. Here, when the selling price is updated, the normal price of the product master 301 is changed, or the selling price is changed to the selling price when the sale is executed.

  When the system is activated, the product data is distributed to all the electronic shelf labels 5 in the store. On the other hand, when the selling price is updated, the product data is distributed only to the electronic shelf labels 5 corresponding to the target product. . Thus, by distributing the product data as necessary, the selling price displayed on the electronic shelf label 5 and the selling price at the time of settlement by the register 32 are always matched.

  In the present embodiment, the product data is distributed by transmitting the entire image from the distribution side device 40 to the electronic shelf label 5. When distributing the product data, two types of whole images, that is, a whole image for horizontal arrangement and a whole image for vertical arrangement are transmitted at the same time.

  That is, first, the product file 101 is referred to by the CPU 11 of the ESL server 10, and the “product code”, “product name” and “sell price (normal price or special price) from the record 102 related to the electronic shelf label 5 to be distributed. Product data such as “is acquired. Then, the CPU 11 generates two whole images for horizontal arrangement and vertical arrangement based on these product data. The two generated whole images are transmitted from the transceiver 42 together with the device code related to the electronic shelf label 5 to be distributed.

  The two transmitted whole images are received by the electronic shelf label 5 to be distributed and stored in the memory 56 of the electronic shelf label 5. Then, under the control of the control unit 55 of the electronic shelf label 5, if the “display mode” is “horizontal mode”, the entire image for horizontal arrangement is displayed on the display 51, and the “display mode” is “vertical mode”. If there is, the entire image for vertical arrangement is displayed on the display 51.

<3-2. Change text direction>
Next, the operation of changing the character direction of characters displayed on the electronic shelf label 5 will be described. In the electronic shelf label 5 of the present embodiment, a radio signal transmitted from the remote controller 79 is accepted, and in response to this, the “display mode” is changed, and the character direction of the character to be displayed is rotated. .

  FIG. 12 is a diagram showing a flow of the operation of the electronic shelf label 5 according to such a change in character direction. In a normal state, the electronic shelf label 5 is in a state of waiting for a remote control signal transmitted from the remote control 79 (step S11). This remote control signal is transmitted based on the operation of the remote staff 79 of the sales staff who is the user, and specifies information indicating “display mode” (designates either “horizontal mode” or “vertical mode”). Information).

  When receiving unit 52 receives the remote control signal (Yes in step S11), the remote control signal is accepted by control unit 55 as a user instruction to rotate the character direction of the character. Then, the “display mode” designated by the remote control signal is confirmed by the control unit 55 (step S12).

  If the “display mode” specified by the remote control signal matches the current “display mode” (No in step S12), the “display mode” does not need to be changed, and the process is terminated.

  On the other hand, when the “display mode” instructed by the remote control signal is different from the current “display mode” (Yes in step S12), the control unit 55 generates a switching signal instructing the change of the “display mode”. (Step S13). In response to the switching signal, the “display mode” is changed, and the entire image corresponding to the changed “display mode” is read from the memory 56 and displayed on the display 51. In other words, if the changed “display mode” is “horizontal mode”, the entire image for horizontal arrangement is displayed. If the changed “display mode” is “vertical mode”, the entire image for vertical arrangement is displayed. (Step S14). Thereby, the whole image displayed on the display 51 is changed, and the character direction of the displayed character is rotated 90 degrees on the screen.

<4. Summary>
As described above, in the electronic shelf label system 1 of the present embodiment, the character direction of characters as product data displayed on the electronic shelf label 5 can be rotated on the screen. For this reason, even when the arrangement direction of the electronic shelf label 5 is changed between the horizontal arrangement and the vertical arrangement, by rotating the character direction of the character displayed on the electronic shelf label 5, the character becomes a normal direction as a language. Can be placed.

  Accordingly, the same electronic shelf label 5 can be used in both the horizontal and vertical arrangement directions, and the versatility of the electronic shelf label 5 can be greatly enhanced. This eliminates the need to prepare a dedicated electronic shelf label such as a vertical type only for some products in which the horizontal width of the face 61 is relatively small, and greatly reduces the cost of the electronic shelf label system 1. Can do.

  Further, even for a product in which the horizontal width of the face 61 varies depending on the number of products in stock, etc., the electronic shelf label 5 is simply arranged in a horizontal arrangement or a vertical arrangement in accordance with the horizontal width of the face 61. If it changes, it can respond and can use the same electronic shelf label 5 continuously about the goods. Therefore, work such as changing the horizontal electronic shelf label to the vertical electronic shelf label is not necessary, and the work efficiency can be improved. Further, since the rotating member 90 is provided on the back side of the electronic shelf label 5, the electronic shelf label 5 can be easily rotated and the arrangement direction can be changed very easily.

  Further, since the character direction of the characters displayed on the electronic shelf label 5 is changed based on the operation of the remote control 79 by the sales staff, the sales staff can change the character direction to the electronic shelf label 5 to be rotated as necessary. Since a user instruction can be given directly, handling is easy.

  In the electronic shelf label 5, two whole images for horizontal arrangement and for vertical arrangement are stored in the memory 56, and the character direction is rotated by changing the whole image to be displayed. For this reason, the character direction can be rotated by the single operation of the electronic shelf label 5, and the operation of the distribution side device 40 is not required. Therefore, the data processing amount of the distribution side device 40 can be reduced.

<5. Other embodiments>
Although the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment (hereinafter referred to as “first embodiment”), and various modifications are possible. Hereinafter, such other embodiments will be described.

<5-1. Second Form: Use of Attitude Sensor>
In the first embodiment, the electronic shelf label 5 changes the character direction based on a user instruction. However, the electronic shelf label 5 has a function of detecting whether the electronic shelf label 5 is vertically or horizontally disposed. The character direction may be automatically changed on the basis of this.

  FIG. 13 is a diagram showing a configuration of the electronic shelf label 5 in the second form in this case. The configuration of the electronic shelf label 5 shown in FIG. 13 is the same as that shown in FIG. 5 except that the electronic shelf label 5 includes an orientation sensor 57 that detects the orientation of the device in the vertical direction.

  As the orientation sensor 57, a sensor that utilizes the change in current caused by the movement of a conductive medium that can move according to the orientation of the electronic shelf label 5, and a sensor that detects the movement of the pendulum member according to the orientation of the electronic shelf label 5. A well-known sensor such as a semiconductor type acceleration sensor that detects triaxial acceleration can be used. The detection result obtained by the attitude sensor 57 is input as a signal to the control unit 55, so that the control unit 55 can recognize whether the arrangement direction of the apparatus is vertical or horizontal.

  FIG. 14 is a diagram showing an operation flow of the electronic shelf label 5 according to the change of the character direction in the second embodiment. In the electronic shelf label 5 of the second form, in a normal state, it is constantly monitored whether or not the posture has been changed. That is, the detection result of the attitude sensor 57 is monitored by the control unit 55, and it is detected whether or not the arrangement direction of the electronic shelf label 5 has been changed from the horizontal arrangement to the vertical arrangement or from the vertical arrangement to the horizontal arrangement (step). S21).

  When a change in posture is detected (Yes in step S21), a switching signal instructing a change in “display mode” is generated by the control unit 55 (step S22). In response to this switching signal, the “display mode” is changed. At this time, the “display mode” is changed to “vertical mode” when the arrangement direction of the electronic shelf label 5 is vertical, and conversely, the “display mode” is set to “horizontal mode” when the electronic shelf label 5 is horizontal. Changed to When the “display mode” is changed in this way, the entire image corresponding to the changed “display mode” is read from the memory 56 and displayed on the display 51 (step S23).

  Thereby, for example, when the arrangement direction of the electronic shelf label 5 is changed from the horizontal arrangement to the vertical arrangement, the entire image displayed on the display 51 is changed from the horizontal arrangement to the vertical arrangement accordingly. Conversely, when the arrangement direction of the electronic shelf label 5 is changed from the vertical arrangement to the horizontal arrangement, the entire image displayed on the display 51 is changed from the vertical arrangement to the horizontal arrangement accordingly. Become.

  Therefore, according to the second embodiment, only the arrangement direction of the electronic shelf label 5 is changed, and the character direction of the displayed character is automatically rotated on the screen. In other words, the characters can be always arranged in a normal direction as a language.

<5-2. Third Mode: User Instruction to Delivery-side Device>
In the first mode, a user instruction to rotate the text direction directly is given to the electronic shelf label 5 using the remote control 79, but the distribution side device 40 is notified using the business terminal 7 or the like. A user instruction may be given.

  FIG. 15 is a diagram showing a flow of operations of the electronic shelf label 5 and the like related to the change of the character direction in the third form in this case. In FIG. 15, the operation indicated by reference sign P7 indicates the operation of the business terminal 7, the operation indicated by reference sign P4 indicates the operation of the distribution side device 40, and the operation indicated by reference sign P5 indicates the operation of the electronic shelf label 5.

  First, the user sales staff performs a predetermined input operation necessary for rotating the character direction of the characters displayed on the electronic shelf label 5 on the business terminal 7 (step S31). In this input operation, an identification code for identifying one electronic shelf label 5 to be rotated in the character direction of the character to be displayed and mode designation information for designating the changed “display mode” are input.

  In response to this input operation, the business terminal 7 transmits a user instruction signal as a user instruction to rotate the character direction to the access point 71 via the wireless LAN. This user instruction signal includes the identification code and mode designation information of the electronic shelf label 5 input by the input operation (step S32).

  The user instruction signal is received by the access point 71 and accepted by the CPU 11 of the ESL server 10 via the LAN 21 (step S33). In response to this, the mode designation information included in the user instruction signal is referenced, and the CPU 11 of the ESL server 10 generates a switching signal as a control signal for the electronic shelf label 5 designating the “display mode”. . This switching signal is transmitted from the transceiver 42 together with the device code included in the user instruction signal. As a result, a switching signal is transmitted to the electronic shelf label 5 whose character direction should be rotated (step S34).

  The transmitted switching signal is received by the electronic shelf label 5 (step S35). In response to the switching signal, in the electronic shelf label 5, when the “display mode” specified by the switching signal is different from the current “display mode”, the “display mode” is changed by the control unit 55. Then, the entire image corresponding to the changed “display mode” is read from the memory 56 and displayed on the display 51. As a result, the entire image displayed on the display 51 is changed, and the character direction of the displayed character is rotated on the screen (step S36).

  Thus, according to the third embodiment, the distribution-side device 40 receives a user instruction to rotate the character direction, generates a switching signal, and transmits it to the electronic shelf label that should rotate the character direction. For this reason, a user instruction can be performed regardless of the position of the electronic shelf label 5 to be rotated in the character direction. That is, even at a position away from the desired electronic shelf label 5, a user instruction can be given to rotate the character direction of the characters displayed on the electronic shelf label 5. In the third embodiment, a user instruction is indirectly given to the distribution side apparatus 40 using the business terminal 7, but directly to the distribution side apparatus 40 via the input unit 16 of the ESL server 10 or the like. Alternatively, a user instruction may be given.

<5-3. Fourth form: Request of whole image to distribution side device>
In the first embodiment, two whole images for horizontal arrangement and for vertical arrangement are stored in advance in the memory 56 of the electronic shelf label 5, but when changing the character direction of the characters displayed on the electronic shelf label 5. The necessary entire image may be acquired from the distribution-side device 40.

  FIG. 16 is a diagram showing a flow of operations of the electronic shelf label 5 and the like in the fourth form in this case. The operation shown in FIG. 16 is performed in place of the operation in step S14 shown in FIG. 12, and the operations in steps S11 to S13 so far are the same as those in the first embodiment. Also in FIG. 16, the operation indicated by reference sign P4 indicates the operation of the distribution side device 40, and the operation indicated by reference sign P5 indicates the operation of the electronic shelf label 5.

  First, the “display mode” is changed in response to the switching signal, and a request signal, which is a radio signal for requesting the entire image corresponding to the changed “display mode”, is sent from the transmitter 53 of the electronic shelf label 5 to the distribution side. Sent to device 40. This request signal includes a device code for specifying the electronic shelf label 5 as a signal source, and image designation information for designating whether the required entire image is for horizontal arrangement or vertical arrangement (step). S41).

  The request signal is received by the transceiver 42 and input to the CPU 11 of the ESL server 10 (step S42). In response to this, the product file 101 is referred to by the CPU 11 of the ESL server 10, product data is acquired from the record 102 corresponding to the device code included in the request signal, and the request is made based on these product data. An entire image corresponding to the image designation information included in the signal is generated. That is, when the image designation information designates “for horizontal arrangement”, an entire image for horizontal arrangement is generated, whereas when “for vertical arrangement” is designated, an entire image for vertical arrangement is generated (step S43). The generated whole image is transmitted from the transceiver 42 together with the device code included in the request signal (step S44).

  The transmitted whole image is received by the electronic shelf label 5 that has transmitted the request signal, and is recorded in the memory 56 (step S45). At this time, the entire image stored in the memory 56 immediately before is deleted. The received whole image is displayed on the display 51 under the control of the control unit 55. Thereby, the whole image displayed on the display 51 is changed, and the character direction of the character to be displayed is rotated on the screen (step S46).

  As described above, according to the fourth embodiment, the electronic shelf label 5 is only used when the entire signal is acquired from the distribution side device 40 only when the switching signal is generated and the character direction needs to be rotated. It is sufficient to store only the entire image in the memory 56, and the amount of data to be stored in the memory 56 can be reduced.

<5-4. Fifth form: transmission of entire image from distribution side device>
The operation of the fourth embodiment shown in FIG. 16 may be employed as the operation of step S23 (see FIG. 14) of the second embodiment or as the operation of step S36 (see FIG. 15) of the third embodiment. However, when applied to the operation of the third embodiment, after the switching signal is transmitted from the distribution side device 40 to the electronic shelf label 5 (FIG. 15: step S34), the whole is based on the request signal from the electronic shelf label 5. The image is further transmitted (FIG. 16: step S44), and the number of communication between the distribution side device 40 and the electronic shelf label 5 increases. For this reason, the switching signal and the entire image may be transmitted from the distribution side device 40 to the electronic shelf label 5 at the same time.

  FIG. 17 is a diagram showing a flow of operations of the electronic shelf label 5 and the like related to the change of the character direction in the fifth form in this case. Also in FIG. 17, the operation indicated by reference sign P7 indicates the operation of the business terminal 7, the operation indicated by reference sign P4 indicates the operation of the distribution side device 40, and the operation indicated by reference sign P5 indicates the operation of the electronic shelf label 5.

  The operations from step S51 to S53 are the same as steps S31 to S33 in FIG. That is, when a predetermined input operation is performed on the business terminal 7 by the sales staff (step S51), a user instruction signal is transmitted from the business terminal 7 (step S52) and accepted by the CPU 11 of the ESL server 10 (step S51). S53).

  In this fifth embodiment, in response to this, the CPU 11 of the ESL server 10 generates a switching signal as a control signal and generates an entire image corresponding to the mode designation information (step S54). Then, the switching signal and the entire image are transmitted from the transceiver 42 together with the device code included in the user instruction signal (step S55).

  The transmitted switching signal and the entire image are received by the electronic shelf label 5 whose character direction is to be rotated (step S56). In response to these receptions, the received whole image is displayed on the display 51 under the control of the control unit 55. As a result, the entire image displayed on the display 51 is changed, and the character direction of the displayed character is rotated on the screen (step S57).

  Thus, according to the fifth embodiment, the number of communications between the distribution side device 40 and the electronic shelf label 5 can be reduced. In addition, it can be said that the operation | movement of a 4th form and a 5th form is an operation | movement which rotates a character direction by displaying the whole image delivered from the delivery side apparatus 40 with generation | occurrence | production of a switching signal.

<5-5. Sixth Form: Use of Layout Data>
In the first embodiment, the entire images for horizontal arrangement and for vertical arrangement are created by the distribution side device 40, and the electronic shelf label 5 merely displays one of the entire images. A necessary whole image may be generated on the bill 5 side.

  FIG. 18 is a diagram conceptually showing a method in which the electronic shelf label 5 of the sixth embodiment in this case creates an entire image. As shown in the drawing, in the memory 56 of the electronic shelf label 5 of the sixth embodiment, image data (hereinafter referred to as “item image”) 83a to 83 for each product data that is not an entire image but a part of the entire image. 83d is stored. More specifically, an item image 83 a indicating eye catch, an item image 83 b indicating selling price, an item image 83 c indicating product name, and an item image 83 d indicating product code are stored in the memory 56.

  Further, the memory 56 stores two layout data 84 and 85 that specify in which position in the whole image and in which direction these item images 83a to 83d are arranged. The layout data 84 and 85 may be either an ASCII format or a binary format, but in any case, the data amount is very small compared to the image data. These item images 83a to 83d and the two layout data 84 and 85 are distributed in advance from the distribution side device 40 as distribution of product data.

  In the sixth embodiment, any one of the two layout data 84 and 85 stored in the memory 56 and the item images 83a to 83d are used and the entire image is displayed by the control unit 55 of the electronic shelf label 5. Is generated, and the generated entire image is displayed on the display 51. Therefore, it can be said that the layout data 84 and 85 specify the character direction and the arrangement position on the screen of the display 51 of the character displayed as the product data.

  One of the two layout data 84 and 85 is layout data 84 for horizontal arrangement, and the other is layout data 85 for vertical arrangement. Then, as shown in the figure, when the entire image is generated using the layout data 84 for horizontal arrangement, the entire image 85 for horizontal arrangement is generated, while the entire image is generated using the layout data 85 for vertical arrangement. Then, the entire image 86 for vertical arrangement is generated. In the sixth embodiment, the direction of characters displayed on the electronic shelf label 5 is rotated by changing layout data to be used.

  FIG. 19 is a diagram showing a flow of operation of the electronic shelf label 5 in the sixth embodiment. The operation shown in FIG. 19 is performed instead of the operation in step S14 shown in FIG. 12, and the operations in steps S11 to S13 so far are the same as those in the first embodiment.

  First, the “display mode” is changed in response to the switching signal, and layout data corresponding to the changed “display mode” is read from the memory 56. That is, if the changed “display mode” is “horizontal mode”, the layout data 84 for horizontal arrangement is read, and if the “display mode” after change is “vertical mode”, the layout data for vertical arrangement is read. 85 is read. Then, the read layout data and the item images 83a to 83d are used to generate an entire image (step S61), and the generated entire image is displayed on the display 51. That is, with the change of the “display mode”, the layout data used for generating the entire image is changed for the horizontal arrangement and the vertical arrangement. Thereby, the entire image displayed on the display 51 is also changed, and the character direction of the displayed character is rotated on the screen (step S62).

  Thus, according to the sixth embodiment, the entire image to be displayed on the display 51 is generated by using the layout data and the item image for each product data. The item images 83a to 83d can be used to create both horizontal and vertical overall images, and the layout data has a very small data amount. Therefore, the memory 56 does not require a large storage capacity for storing two entire images, and a storage means having a relatively small storage capacity can be employed.

  Also in the sixth embodiment, the character direction is rotated only by changing the layout data used for generating the entire image. Therefore, the character direction can be rotated by the single operation of the electronic shelf label 5, and the operation of the distribution side device 40 is performed. Therefore, the data processing amount of the distribution side device 40 can be reduced.

  The operation shown in FIG. 19 of the sixth embodiment is applied instead of the operation of step S14 of the first embodiment, but as the operation of step S23 (see FIG. 14) of the second embodiment, or You may employ | adopt as operation | movement of step S36 (refer FIG. 15) of a 3rd form.

<5-6. Seventh embodiment: Request of layout data from distribution side device>
Further, in the fourth embodiment, a necessary whole image is acquired from the distribution side device 40. However, necessary layout data may be acquired from the distribution side device 40. In the seventh form in this case, the same item images 83a to 83d as in the sixth form and the layout data for only one of the horizontal arrangement and the vertical arrangement are used as distribution apparatus for distributing product data. 40 is distributed in advance and stored in the memory 56 of the electronic shelf label 5.

  FIG. 20 is a diagram showing a flow of operations of the electronic shelf label 5 and the like in the seventh embodiment. The operation shown in FIG. 20 is performed in place of the operation in step S14 shown in FIG. 12, and the operations in steps S11 to S13 are the same as those in the first embodiment. Also in FIG. 20, the operation indicated by reference sign P4 indicates the operation of the distribution side device 40, and the operation indicated by reference sign P5 indicates the operation of the electronic shelf label 5.

  First, the “display mode” is changed in response to the switching signal, and a request signal, which is a radio signal for requesting layout data corresponding to the changed “display mode”, is sent from the transmitter 53 of the electronic shelf label 5 to the distribution side. Sent to device 40. This request signal includes a device code for specifying the electronic shelf label 5 as a signal source and layout designation information for designating whether the required layout data is for horizontal arrangement or vertical arrangement (step). S71).

  The request signal is received by the transceiver 42 and input to the CPU 11 of the ESL server 10 (step S72). In response to this, under the control of the CPU 11 of the ESL server 10, layout data corresponding to the layout designation information included in the request signal is transmitted from the transceiver 42 together with the device code included in the request signal. That is, when the layout designation information designates “for horizontal placement”, layout data for horizontal placement is transmitted, and when “for vertical placement” is designated, layout data for vertical placement is transmitted (step S73). .

  The transmitted layout data is received by the electronic shelf label 5 that has transmitted the request signal, and is recorded in the memory 56 (step S74). At this time, the layout data stored in the memory 56 immediately before is deleted. The received layout data and the item images 83a to 83d are used to generate an entire image by the control unit 55 of the electronic shelf label 5 (step S75), and the generated entire image is displayed on the display 51. . As a result, the entire image displayed on the display 51 is changed, and the character direction of the displayed character is rotated on the screen (step S76).

  As described above, according to the seventh embodiment, when the switching signal is generated and it is necessary to rotate the character direction, the electronic shelf label 5 is used to acquire the necessary layout data from the distribution side device 40. Only the layout data need be stored in the memory 56, and the amount of data to be stored in the memory 56 can be further reduced. Further, since only the layout data is transmitted from the distribution side device 40, the amount of data to be transmitted by the distribution side device 40 can also be reduced.

  The operation shown in FIG. 20 of the seventh embodiment is applied instead of the operation of step S14 of the first embodiment, but as the operation of step S23 (see FIG. 14) of the second embodiment, or You may employ | adopt as operation | movement of step S36 (refer FIG. 15) of a 3rd form.

<5-7. Eighth mode: transmission of layout data from distribution side device>
In the fifth embodiment, the entire image is transmitted from the distribution side device 40 together with the switching signal. However, the layout data may be transmitted together with the switching signal. Also in the eighth form in this case, the same item images 83a to 83d as in the sixth form and the layout data for only one of the horizontal arrangement and the vertical arrangement are used as distribution apparatus for distributing the product data. 40 is distributed in advance and stored in the memory 56 of the electronic shelf label 5.

  FIG. 21 is a diagram illustrating an operation flow of the electronic shelf label system 1 according to the change of the character direction in the eighth embodiment. Also in FIG. 21, the operation indicated by reference sign P7 indicates the operation of the business terminal 7, the operation indicated by reference sign P4 indicates the operation of the distribution side device 40, and the operation indicated by reference sign P5 indicates the operation of the electronic shelf label 5.

  The operations from step S81 to S83 are the same as steps S31 to S33 in FIG. That is, when a predetermined input operation is performed on the business terminal 7 by the sales staff (step S81), a user instruction signal is transmitted from the business terminal 7 (step S82) and accepted by the CPU 11 of the ESL server 10 (step S82). S83).

  In the eighth mode, in response to this, the CPU 11 of the ESL server 10 generates a switching signal as a control signal. Then, the switching signal and the layout data corresponding to the user instruction signal included in the request signal are transmitted from the transceiver 42 together with the device code included in the request signal (step S84).

  The transmitted switching signal and layout data are received by the electronic shelf label 5 whose character direction is to be rotated (step S85). In response to the reception, the received layout data and the item images 83a to 83d are used to generate an entire image by the control unit 55 of the electronic shelf label 5 (step S86). An image is displayed on the display 51. Thereby, the whole image displayed on the display 51 is changed, and the character direction of the character to be displayed is rotated on the screen (step S87).

  Thus, according to the eighth embodiment, the number of communications between the distribution side device 40 and the electronic shelf label 5 can be reduced. Both the operations of the seventh and eighth embodiments rotate the character direction by displaying the entire image generated using the layout data distributed from the distribution side device 40 in response to the generation of the switching signal. It can be said that this is an action to perform.

<5-8. Other variations>
In the first embodiment, two whole images for horizontal arrangement and for vertical arrangement are stored in the memory 56. However, the arrangement directions other than the arrangement directions of the electronic shelf labels 5 corresponding thereto (for example, An entire image corresponding to 45 degrees with respect to the vertical direction or an arrangement different from the normal horizontal arrangement or vertical arrangement by 180 degrees is further stored in the memory 56, and the arrangement direction (arrangement angle) of the electronic shelf label 5 is stored. Depending on the situation, it may be changed as appropriate and displayed. Similarly, in the sixth embodiment, layout data corresponding to an arrangement direction other than the arrangement direction of the electronic shelf labels 5 corresponding to the horizontal arrangement and the vertical arrangement is further stored in the memory 56, and the arrangement of the electronic shelf labels 5 is determined. You may change the layout data used according to a direction (arrangement angle).

  In the first embodiment, a user instruction is given to the electronic shelf label 5 using the remote control 79. For example, the electronic shelf label 5 is provided with a switch as a physical mechanism unit. The switching of the contact may be a user instruction to rotate the character direction. For example, when a slide-type switch is provided and the switch is slid to one side, an instruction to set the “display mode” to “horizontal mode” is given, and when the switch is slid to the other side, the “display mode” is set. An instruction to switch to “vertical mode” may be given.

  In addition, the contact of such a switch may be switched in conjunction with the relative positional relationship between the shelf label side member 91 and the fixed side member 92 of the rotating member. According to this, when the arrangement direction of the electronic shelf label 5 is changed, the contact point of the switch is switched in conjunction with it, and the character direction of the displayed character is rotated on the screen. For this reason, the characters can be always arranged in a normal direction as a language without any special work of the sales staff.

  In the sixth to eighth embodiments, it has been described that the product data is stored in advance in the memory 56 as an item image. However, the font data is stored in advance in the memory 56, a dedicated ROM, etc. The item image may be generated from the product data in the format. That is, in this case, the entire image is generated from the ASCII product data, font data, and layout data.

  Further, when font data is used in this way, it is easy to change the size and arrangement of the characters themselves. For this reason, the characters may be displayed so that the character arrangement such as the arrangement direction and size of the character strings differs between the horizontal arrangement and the vertical arrangement of the electronic shelf label 5. For example, as shown in FIG. 22, when the arrangement direction of the electronic shelf label 5 is set to the vertical arrangement, a character string indicating the selling price may be arranged in the vertical direction so that the characters are enlarged as compared with the horizontal arrangement. It is done.

  By the way, each electronic shelf label 5 may incorporate a wireless antenna and an IC chip such as RFID, and the product data transmitted from the transceiver 42 may be stored in the IC chip.

  In this way, by holding a portable reader / writer terminal having a communication function with the IC chip over each electronic shelf label 5, product data relating to the corresponding product (product name, purchase cost, normal price) , Sale price, shelf number, number of displays, product shelf inventory theoretical value, backyard inventory, sales information (daily, weekly, monthly, etc.) can be checked instantly on the screen of a portable reader / writer terminal Can do.

  That is, without giving a user instruction to the electronic shelf label 5 by operating the remote control 79 or the like, and without switching the display content of the screen of the electronic shelf label 5, the product data relating to the corresponding product is read using the reader / writer terminal. I can confirm. For this reason, various product data can be confirmed without considering the customer even during the business hours of the store. In addition, since digital information obtained from the IC chip is input to the reader / writer terminal, it is possible to completely prevent an erroneous input.

  In this case, if an IC chip reader / writer device is provided in the product shelf 60, the reader / writer device and the IC chip built in each electronic shelf label 5 are communicated to accurately grasp the shelf position. It becomes possible to do. As a result, inventory work and shelf position change work can be easily performed. For example, when changing the shelf position, information on both the shelf positions before and after the change is transmitted via the transceiver 42 and stored in the IC chip of the electronic shelf label 5. Thus, the worker can hold the reader / writer terminal over the electronic shelf label 5 and change the shelf position while checking the screen displayed on the reader / writer terminal.

  In addition, when each product includes a product tag (IC chip) such as RFID, a reader / writer device provided in the product shelf 60 reads the data of the product tag, and further, in the IC chip of the electronic shelf label 5. If written, the product tag data can be displayed on the display 51 of the electronic shelf label 5.

  In addition, if the IC chip reader / writer device is provided in the shopping cart handled by the customer in the store and the IC chip data of the electronic shelf label 5 is read into the shopping cart reader / writer device, the customer flow line can be easily investigated. Can be done. Furthermore, it is also possible to display the special price on the display of the shopping cart by providing a display on the reader / writer device and acquiring a special price (so-called member price) for a specific customer from the IC chip of the electronic shelf label 5 It is. In this case, the reader / writer device may be made to recognize that the customer using the shopping cart is a specific customer by inserting a membership card.
