[0071] The printed circuit board (720) is electrically connected to the display device (710) so as to drive the display device (710).

[0072] For example, a display device (710) is provided on the front of a printed circuit board (720), and the printed circuit board (720) and the display device (710) can be electrically connected to each other through a flexible connection structure (20).

[0073] One or more electronic components for driving the electronic shelf label (70) may be mounted on the front or rear of the printed circuit board (720). The printed circuit board (720) may have a plate shape. The printed circuit board (720) may receive power from a battery provided in the first storage groove (101) of the rail body part (100).

[0074] Meanwhile, referring to FIG. 5, the printed circuit board (720) may include at least one conductive pin (p1, p2, p3, p4) that receives power from an external source.

[0075] For example, a first pin (p1), a second pin (p2), a third pin (p3), and a fourth pin (p4) may be provided on the back of the printed circuit board (720).

[0076] The first pin (p1), the second pin (p2), the third pin (p3), and the fourth pin (p4) may have different heights from each other. For example, each of at least one pin (p1, p2, p3, p4) may include a horizontal portion (21) extending from the rear surface of the printed circuit board (720), a vertical portion (22) extending from one end of the horizontal portion (21), and a fastening portion (23) provided at one end of the vertical portion (22) and formed to have a hook shape.

[0077] In this case, as the height of each of the vertical portions (22) of at least one pin (p1, p2, p3, p4) is designed to be different from each other, the heights of at least one pin (p1, p2, p3, p4) may be different from each other.

[0078] In addition, as the length of each horizontal portion (21) of at least one pin (p1, p2, p3, p4) is designed to be the same, the lengths of at least one pin (p1, p2, p3, p4) extended from the rear surface of the printed circuit board (720) may be equal to each other.

[0079] The mounting portion (730) may include a mounting main body portion (731), a mounting portion horizontal extension portion (732) extending from the rear of the mounting main body portion (731), and a mounting portion vertical extension portion (733) extending from the upper surface of the mounting portion horizontal extension portion (732).

[0080] The mounting body (731) may have a predetermined plate shape. In this case, the mounting body (731) may include a housing shape that provides an internal space where a printed circuit board (720) can be provided.

[0081] The front of the mounting body (731) can be connected to the rear of the display device (710). For example, the front of the mounting body (731) and the rear of the display device (710) can be connected to each other by bonding the outermost perimeter of the front of the mounting body (731) and the outermost perimeter of the rear of the display device (710).

[0082] Additionally, the mounting body (731) may include a plurality of first protrusions (734) provided on the upper surface. The plurality of first protrusions (734) may be provided on the upper surface of the mounting body (731) at regular intervals. In this case, the plurality of first protrusions (734) may form a predetermined gear shape.

[0083] Furthermore, the mounting body (731) may include at least one first hole (h1, h2, h3, h4) into which at least one pin (p1, p2, p3, p4) of the printed circuit board (720) is inserted. For example, at least one first hole (h1, h2, h3, h4) into which at least one pin (p1, p2, p3, p4) is inserted may be provided in a part of the mounting body (731), formed to penetrate the front and rear surfaces of the mounting body (731). At least one pin (p1, p2, p3, p4) can penetrate the mounting body (731) by being inserted into at least one first hole (h1, h2, h3, h4).

[0084] For example, referring to FIGS. 5 and 6, first-1 to first-4 holes (h1, h2, h3, h4) corresponding to first to fourth pins (p1, p2, p3, p4) of a printed circuit board (720) may be formed in a part of the mounting body (731). The first pin (p1) may be inserted into the first-1 hole (h1), the second pin (p2) may be inserted into the first-2 hole (h2), the third pin (p3) may be inserted into the first-3 hole (h3), and the fourth pin (p4) may be inserted into the first-4 hole (h4). In this case, the heights of the 1-1 to 1-4 holes (h1, h2, h3, h4) can be designed to be equal in height sufficiently large to allow the 1st pin (p1), which has the largest height among the 1st to 4th pins (p1, p2, p3, p4), to be inserted.

[0085] The horizontal extension portion (732) of the mounting portion can be formed by extending outwardly by a predetermined length vertically from one edge area of ​​the rear of the mounting main body portion (731) to the rear of the mounting main body portion (731).

[0086] The vertical extension portion (733) of the mounting portion can be formed by extending upward for a predetermined length from the end of the upper surface of the horizontal extension portion (722) of the mounting portion. Accordingly, the rear surface of the mounting main body portion (731) and the vertical extension portion (733) of the mounting portion can be spaced apart by a predetermined distance.

[0087] The vertical extension portion (733) of the mounting portion may include at least one hook (hk1, hk2, hk3, hk4) to which at least one pin (p1, p2, p3, p4) of the printed circuit board (720) is fastened.

[0088] For example, the vertical extension portion (733) of the mounting portion may include first to fourth hooks (hk1, hk2, hk3, hk4) corresponding to first to fourth pins (p1, p2, p3, p4). In this case, the first to fourth hooks (hk1, hk2, hk3, hk4) may be formed to have a shape that engages with the fastening portion (23) of the first to fourth pins (p1, p2, p3, p4).

[0089] The first to fourth hooks (hk1, hk2, hk3, hk4) can be designed to have different heights from each other, and accordingly, can correspond to the first to fourth pins (p1, p2, p3, p4) having different heights.

[0090] Additionally, the vertical extension portion (733) of the mounting portion may include a front plate (741) formed extending from the upper surface of the horizontal extension portion (732) of the mounting portion, a connecting portion (742) formed extending from the rear surface of the front plate (741), and a rear plate (743) formed extending from the lower surface of the connecting portion (742). The front plate (741), the connecting portion (742), and the rear plate (743) may be formed to surround a predetermined empty space, and accordingly, the front plate (741) and the rear plate (743) may be spaced apart at a predetermined distance in the front-rear direction. The front plate (741), the connecting portion (742), and the rear plate (743) may be formed integrally and may have a predetermined elasticity.

[0091] In this case, the vertical extension portion (733) of the mounting portion may include a pressure portion (736, 737) that extends from the lower part of the rear plate (743) and transmits external pressure to the rear plate (743). For example, a first pressure portion (736) and a second pressure portion (737) may be formed extending downward in the direction of the rear plate (743) at the lower part of the rear plate (743). The first pressure portion (736) and the second pressure portion (737) may be formed to be separated by a predetermined space between them in the center. However, this is not limited thereto, and the first pressure portion (736) and the second pressure portion (737) may be connected and formed as an integral unit.

[0092] External pressure directed from the rear to the front may be applied by the user to the first pressure part (736) and the second pressure part (737), and this external pressure is transmitted to the rear plate (743), thereby narrowing the distance between the rear plate (743) and the front plate (741).

[0093] Additionally, at least one hook (hk1, hk2, hk3, hk4) may be formed on the rear plate (743). For example, the first to fourth hooks (hk1, hk2, hk3, hk4) may be arranged side by side in an area of ​​the rear plate (743) to correspond to the first to fourth holes (h1, h2, h3, h4) of the mounting body part (731).

[0094] For example, a portion of at least one hook (hk1, hk2, hk3, hk4) may be formed integrally with the rear plate (743), and the end of at least one hook (hk1, hk2, hk3, hk4) may be formed to extend from the rear plate (743) in the front direction. Accordingly, the end of at least one pin (p1, p2, p3, p4) passing through at least one first hole (h1, h2, h3, h4) of the mounting body part (731) may face the end of at least one hook (hk1, hk2, hk3, hk4).

[0095] In this case, if pressure is applied in the rearward direction to at least one pin (p1, p2, p3, p4), the end of at least one pin (p1, p2, p3, p4) and the end of at least one hook (hk1, hk2, hk3, hk4) can be engaged and fastened together. For example, a user can use a plate-shaped jig to simultaneously apply pressure to the first-1 to first-4 pins (p1, p2, p3, p4) so ​​that the first-1 to first-4 pins (p1, p2, p3, p4) and the first-4 hooks (hk1, hk2, hk3, hk4) are fastened together.

[0096] For example, referring to FIG. 8, a pin fastening device (50) for connecting at least one pin (p1, p2, p3, p4) of a printed circuit board (720) to at least one hook (hk1, hk2, hk3, hk4) formed on the rear plate (743) of a mounting part (730) can be designed separately from the electronic shelf label (70).

[0097] For example, the pin fastening device (50) may include a plate-shaped jig (51) for mounting an electronic shelf label (70), a body part (52) on which the jig (51) is provided, a plurality of pressure devices (53) for applying pressure to the jig (51), a pressure device support part (54) for supporting the plurality of pressure devices (53), and a plurality of electronic shelf label support parts (S1, S2, S3, S4) provided on the body part (52) to support the plurality of electronic shelf labels (70).

[0098] A plurality of electronic shelf label support members (S1, S2, S3, S4) may be arranged side by side at regular intervals in a portion of the upper surface of the body part (52). Each of the plurality of electronic shelf label support members (S1, S2, S3, S4) may be arranged to support the front surface of a plurality of electronic shelf labels (70).

[0099] The jig (51) is a member having a plate shape and can be arranged to face in the vertical direction a plurality of electronic shelf label support members (S1, S2, S3, S4) arranged side by side. At this time, the jig (51) and the plurality of electronic shelf label support members (S1, S2, S3, S4) can be spaced apart in the vertical direction at a predetermined equal interval.

[0100] For example, the first region of the jig (51) may face the first electronic shelf label support (S1) at a predetermined distance, the second region of the jig (51) may face the second electronic shelf label support (S2) at a predetermined distance, the third region of the jig (51) may face the third electronic shelf label support (S3) at a predetermined distance, and the fourth region of the jig (51) may face the fourth electronic shelf label support (S4) at a predetermined distance.

[0101] Each of the plurality of electronic shelf labels (70) can be placed in the space between the jig (51) and each of the plurality of electronic shelf label support parts (S1, S2, S3, S4). For example, the mounting body part (710) of the plurality of electronic shelf labels (70) can be fitted into the space between the jig (51) and each of the plurality of electronic shelf label support parts (S1, S2, S3, S4), and the mounting vertical extension part (733) of the plurality of electronic shelf labels (70) can be placed on the upper surface of the jig (51).

[0102] A plurality of pressure devices (53) may be supported by a pressure device support portion (54) formed to protrude upward from the upper surface of the body portion (52). A plurality of pressure devices (53) may be formed to move in an up-and-down direction to apply pressure to the jig (51). A plurality of pressure devices (53) may include a contact portion that contacts the jig (51) and a motor portion that provides driving force to move the contact portion in an up-and-down direction.

[0103] In this case, each of the plurality of pressure devices (53) may be arranged to face the mounting vertical extension (733) of the plurality of electronic shelf labels (70) placed on the jig (51).

[0104] As the contact portion of the plurality of pressure devices (53) moves downward, it comes into contact with the mounting vertical extension portion (733) of the plurality of electronic shelf labels (70) placed on the jig (51), and subsequently, as the contact portion of the plurality of pressure devices (53) moves further downward, pressure is applied to the mounting vertical extension portion (733) of the plurality of electronic shelf labels (70), so that at least one hook (hk1, hk2, hk3, hk4) included in the rear plate (743) of the mounting vertical extension portion (733) and at least one pin (p1, p2, p3, p4) facing it can be fastened together.

[0105] In this manner, with a plurality of electronic shelf labels (70) mounted on a plurality of electronic shelf label supports (S1, S2, S3, S4), a plurality of pressure devices (53) can be operated to move downward in a batch, thereby allowing at least one pin (p1, p2, p3, p4) and at least one hook (hk1, hk2, hk3, hk4) of the plurality of electronic shelf labels (70) to be connected simultaneously.

[0106] The rear plate (743) may include at least one second hole (h5, h6, h7, h8) that exposes at least one hook (hk1, hk2, hk3, hk4) to the outside. For example, the rear plate (743) may include 2-1 to 2-4 holes (h5, h6, h7, h8) that expose first to fourth hooks (hk1, hk2, hk3, hk4) to the outside, formed so that their ends extend from the rear plate (743) toward the front.

[0107] In this case, the 2-1 to 2-4 holes (h5, h6, h7, h8) may be formed to expose the ends of the 1 to 4 hooks (hk1, hk2, hk3, hk4). The heights of the 1 to 4 hooks (hk1, hk2, hk3, hk4) may differ from each other, and accordingly, the coordinates in the vertical direction on the rear plate (743) of the 2-1 to 2-4 holes (h5, h6, h7, h8) may differ from each other.

[0108] For example, referring to (A) of FIG. 7, the end of the first hook (hk1) facing the first pin (p1) is exposed through the second-1 hole (h5); referring to (B) of FIG. 7, the end of the second hook (hk2) facing the second pin (p2) is exposed through the second-2 hole (h6); referring to (C) of FIG. 7, the end of the third hook (hk3) facing the third pin (p3) is exposed through the second-3 hole (h7); and referring to (D) of FIG. 7, the end of the fourth hook (hk4) facing the fourth pin (p4) is exposed through the second-4 hole (h8).

[0109] Additionally, the rear plate (743) may include at least one array insertion protrusion (735) formed to be inserted into the array hole (320) of the array section (300) described later. The array insertion protrusion (735) may be formed to protrude rearward from the rear of the rear plate (743).

[0110] For example, the rear plate (743) may be provided with a plurality of array insertion protrusions (735) spaced apart at a predetermined distance in the left and right directions at a certain height.

[0111] In this case, the first region (751) and the second region (753), which are provided with a plurality of array insertion protrusions (735) of the rear plate (743), may be partially separated through a third region (752) and a predetermined third hole (h9), which are provided with a plurality of second holes (h5, h6, h7, h8) of the rear plate (743).

[0112] In this case, the first pressure part (736) may extend from the lower part of the first region (751) of the rear plate (743), and the second pressure part (737) may extend from the lower part of the second region (753) of the rear plate (743). Accordingly, the first and second regions (751, 753) of the rear plate (743) may move in the front direction due to the pressure applied to the first and second pressure parts (736, 737), and the third region (753) may not move.

[0113] In this way, as the first and second regions (751, 753) of the rear plate (743) move in the front direction due to the pressure applied to the first and second pressure parts (736, 737), the plurality of array insertion protrusions (735) provided in the first and second regions (751, 753) can be separated from the array hole (320), and the connection between the electronic shelf label (70) and the array part (300) can be released, thereby allowing the electronic shelf label (70) to be detached from the power rail (10).

[0114] Meanwhile, the mounting body (731) of the electronic shelf label (70) is not limited to what is illustrated and can be configured in various forms depending on the type of electronic shelf label (70). For example, various devices such as ESLs as tags of various sizes, Cam tags, and Solar tags may be installed. In addition, the display device (710) of the electronic shelf label (70) may vary in size. Furthermore, the electronic shelf label (70) may include various additional devices. For example, the electronic shelf label (70) may include a camera device and a driving device for changing the shooting angle of the camera. In various embodiments, a connector may be installed in the rail body (100), and the electronic shelf label (70) may be attached to the rail body (100) through the connector, and various items may be attached to the connector.

[0115] The rail body (100) may be composed of a front surface (110) corresponding to the rear surface of the electronic shelf label (70), a rear surface (120) corresponding to the shelf (90), an upper surface (130), and a lower surface (140). Additionally, a first storage groove (101) may be formed on the inner side of the rail body (100) surrounded by the front surface (110), the rear surface (120), the upper surface (130), and the lower surface (140).

[0116] The rail body (100) may include an upper plate (131), a lower plate (141), a front plate (111), and a rear plate (121). The upper plate (131), lower plate (141), front plate (111), and rear plate (121) may be formed integrally with each other. The upper plate (131), lower plate (141), front plate (111), and rear plate (121) constitute a part of the rail body (100), and a first storage groove (101) is formed by the inner space surrounded by the upper plate (131), lower plate (141), front plate (111), and rear plate (121). A space with four closed sides like this can be used to store a controller and a battery, and the appearance can be simple and durability can be increased.

[0117] On the rear side of the upper plate (131), a rear protrusion (132) of the upper plate is formed that protrudes in the rearward direction parallel to the upper surface of the upper plate (131), and on the front side of the upper plate (131), a front protrusion (134) of the upper plate is formed that protrudes in the frontward direction parallel to the upper surface of the upper plate (131).

[0118] A first fastening latch portion (133) extending downward from the end of the upper plate (131) may be formed on the upper plate (131). A predetermined space may be formed between the first fastening latch portion (133) and the end of the rear plate (121).

[0119] A second fastening latch portion (135) may be formed on the front protrusion (134) of the upper plate. The second fastening latch portion (135) may be formed as a latch type by extending a predetermined distance downward from the end of the front protrusion (134) of the upper plate and then extending a predetermined distance in the rearward direction.

[0120] When the rail body part (100) is connected to the shelf connection part (91) to be described later, the rear protrusion (132) of the upper plate covers the connection point between the rail body part (100) and the shelf connection part (91). Thus, the connection area between the rail body part (100) and the shelf connection part (91) is finished. Additionally, when the rail body part (100) is connected to the electronic shelf label (70) to be described later, the front protrusion (134) of the upper plate covers the connection point between the rail body part (100) and the electronic shelf label (70). Thus, the connection area between the rail body part (100) and the electronic shelf label (70) is finished.

[0121] A first and second extension portion (150, 160) may be formed on the lower plate (141) constituting the lower surface (140) of the rail body part (100). That is, a first and second extension portion (150, 160) may be formed extending downward from one area of ​​the lower surface (140). That is, the first extension portion (150) may be formed extending perpendicularly from the edge area of ​​the lower surface (140) to the lower surface (140), and the second extension portion (160) may be formed extending perpendicularly from one area of ​​the lower surface (140) to the lower surface (140) and spaced apart from the first extension portion (150) by a predetermined distance, and the first and second extension portions (150, 160) may be positioned parallel to each other.

[0122] The front surface of the first extension part (150) may form a part of the front surface (110) of the rail body part (100). That is, the first extension part (150) may be integrally formed with the front plate (111) to form a single plate. In addition, the front surface of the first extension part (150) and the front surface (110) of the rail body part (100) may form the same plane. At the end of the first extension part (150), a first extension protrusion (151) may be formed so as to extend toward the second extension part (160) for a predetermined length and then protrude upward for a predetermined length to form a latch, and at the end of the second extension part (160), a second extension protrusion (161) may be formed so as to extend toward the first extension part (150) for a predetermined length and then protrude upward for a predetermined length to form a latch.

[0123] The first extension protrusion (151) may be extended from the first extension (150) in a direction perpendicular to the length direction of the first extension (150) and then extended upward in a direction parallel to the length direction of the first extension (150), and the second extension protrusion (161) may be extended from the second extension (160) in a direction perpendicular to the length direction of the second extension (160) and then extended parallel to the length direction of the second extension (160). In addition, the ends of the first and second extension protrusions (151, 161) may be spaced apart by a first distance. In addition, the vertical distance between the first extension (150) and the second extension (160) may be spaced apart by a second distance that is longer than the first distance. In addition, a second storage groove (102) may be formed inside by the first extension part (150), the second extension part (160), and the first and second extension protrusion parts (151, 161). The second storage groove (102) may be located below the first storage groove (101).

[0124] A protective portion (162) may be formed on the second extension portion (160) and extended at a predetermined angle in the rearward and upward directions from the end of the second extension portion (160). The protective portion (162) may be formed extending from the end of the second extension portion (160) with a predetermined slope. When the rail main body portion (100) and the shelf fastening portion (91) are fastened together, the protective portion (162) covers the fastening point on the lower part of them to provide a finishing finish. Additionally, due to the protective film structure of the protective portion (162), the product on the shelf is not caught, and the power rail (10) can be firmly fastened to the shelf while covering the fastening structure between the rail main body portion (100) and the shelf fastening portion (91).

[0125] Additionally, a fastening protrusion (163) may be formed that protrudes downward from a point on the lower plate (141) and extends backward. That is, an 'L'-shaped fastening protrusion (163) may be formed that protrudes downward from a region of the lower surface of the lower plate (141). A first space (103) surrounded by the fastening protrusion (163) and a part of the lower plate (141) may be defined.

[0126] Additionally, first and second inner protrusions (142, 143) protruding downward from the lower surface of the lower plate (141) may be formed. The first and second inner protrusions (142, 143) may be formed within the second storage groove (102). The first and second inner protrusions (142, 143) may be positioned spaced apart from each other.

[0127] The power rail (10) may be equipped with an electrode structure and an array hole structure capable of attaching an electronic shelf label (70) and various sensors.

[0128] The electrode portion (200) and the array portion (300) are stored in the second storage groove (102) and can be fastened to the first and second extension portions (150, 160).

[0129] The electrode portion (200) may include an electrode body portion (210), an elastic adhesive portion (220) attached to the front surface of the electrode body portion (210), and a rail electrode (230) installed on the rear surface of the electrode body portion (210).

[0130] The elastic adhesive portion (220) may be formed along the longitudinal direction of the electrode body portion (210), and the rail electrode (230) may be formed along the longitudinal direction of the electrode body portion (210). The rail electrode (230) may include at least one of a ground electrode, a power supply electrode, and a data transmission electrode.

[0131] The rail electrode (230) may include first to fourth rail electrodes, which may be spaced apart from each other in the vertical direction at regular intervals and positioned parallel to each other. For example, the rail electrode (230) may include first to fourth rail electrode thin plate flat electrodes. In this way, by applying a high-precision thin plate flat electrode structure to the power rail (10), productivity can be greatly improved.

[0132] When the electrode portion (200) is inserted into the second storage groove (102), the rear surface of the elastic adhesive portion (220) is attached to the front surface of the electrode body portion (210), and the front surface of the elastic adhesive portion (220) can be attached to the rear surface of the first extension portion (150). In addition, the upper surface of the electrode body portion (210) corresponds to the first inner protrusion (142), and the lower surface of the electrode body portion (210) corresponds to the first extension protrusion (151).

[0133] Additionally, the array section (300) may include an array main body section (310). An array hole (320) may be formed in the array main body section (310). The array hole (320) may be formed to penetrate the center of the array main body section (310) and may be configured as a hole extending along the longitudinal direction of the array main body section (310). The array hole (320) may be formed as a hole penetrating the front and rear of the array main body section (310).

[0134] In this case, the array main body (310) may include two plate shapes spaced apart from each other with the array hole (320) in between. However, it is not limited thereto, and the array main body (310) may be formed to include a 'C' shape in which the two plate shapes are connected at one end.

[0135] Array protrusions (331, 332) may be formed on the array main body (310). The array protrusions (331, 332) may include a first array protrusion (331) protruding along the length direction of the array main body (310) in a portion of the upper surface of the array main body (310), and a second array protrusion (332) protruding along the length direction of the array main body (310) in a portion of the lower surface of the array main body (310).

[0136] When the array portion (300) is inserted into the second storage groove (102), the rear surface of the array main body portion (310) faces the front surface of the second extension portion (160), and they can come into contact with each other. Then, the first array protrusion (331) is fitted into the space between the second inner protrusion (143) and the second extension portion (160), and the second array protrusion (332) is fitted into the space between the second extension protrusion (161) and the second extension portion (160), so that the array portion (300) can be fastened onto the second storage groove (102).

[0137] Meanwhile, the array section (300) may be formed integrally with the power rail (10) while inserted into the second storage groove (102). In this case, the array section (300) may be designed so that it is not detached from the second storage groove (102) and is formed integrally during the process of forming the power rail (10).

[0138] Additionally, referring to FIG. 14, when the mounting body (731) is connected to the power rail (10), a plurality of first protrusions (734) provided on the upper surface of the mounting body (731) can be engaged with a plurality of second protrusions (136) provided on the lower surface of the second connecting latch (135) of the rail body (100).

[0139] For example, any one of the multiple second protrusions (136) may be located in the space between any two of the multiple first protrusions (734). In this way, the first gear rail formed by the multiple first protrusions (734) and the second gear rail formed by the multiple second protrusions (136) interlock with each other, so that the electronic shelf label (70) can be stably fixed to the power rail (10).

[0140] Furthermore, referring to FIG. 15, when the mounting body (731) is connected to the power rail (10), the electronic shelf label (70) can be configured to move in the left and right directions relative to the second connecting latch (135) of the power rail (10) by means of a connecting gear structure provided inside the mounting body (731).

[0141] For example, inside the mounting body (731), a rotating gear (60) that is partially exposed to the upper surface of the mounting body (731), a rail gear (61) configured to move left and right while engaged with the rotating gear (60), and a driving motor (62) that provides driving force for the rail gear (61) to move left and right may be provided.

[0142] A portion of the rotating gear (60) is exposed to the outside through a hole provided on the upper surface of the mounting body (731) and can engage with the second protrusion (136) of the second fastening latch (135).

[0143] The driving motor (62) can be operated by a control signal from an external server or user terminal to transmit driving force to the rail gear (61) and the rotating gear (60), and accordingly, the position of the electronic shelf label (70) can be changed by the rotating gear (60) moving relative to the second protrusion (136).

[0144] In this way, the left and right movement of the electronic shelf label (70) on the power rail (10) can be controlled by controlling the fastening gear structure provided inside the electronic shelf label (70), and accordingly, the position of the electronic shelf label (70) on the power rail (10) can be easily changed through central control.

[0145] Additionally, referring to FIGS. 16 and 17, distance sensors (71, 72) may be provided on the left and right sides of the electronic shelf label (70), and when the electronic shelf label (70) moves to the left or right side on the power rail (10), the electronic shelf label (70) may be controlled to maintain a predetermined distance from the adjacent electronic shelf label (70) based on distance information to the adjacent electronic shelf label (70) obtained by the distance sensors (71, 72).

[0146] When the electronic shelf label (70) and the power rail (10) for the electronic shelf label are connected to each other, the first extension part (150) of the rail body part (100) can be inserted into the space between the mounting body part (731) and the mounting part vertical extension part (733). On the front of the mounting part vertical extension part (733), at least one terminal pin (p1, p2, p3, p4) can be exposed through at least one second hole (h5, h6, h7, h8).

[0147] When the vertical extension part (733) of the mounting part is inserted into the second storage groove (102), the rail electrode (230) of the electrode part (200) and the first to fourth pins (p1, p2, p3, p4) can be electrically connected to each other. At this time, the first to fourth pins (p1, p2, p3, p4) may have different heights, and the first to fourth rail electrodes and the first to fourth pins (p1, p2, p3, p4) may be connected to each other in a 1:1 ratio.

[0148] The electronic lathe label (70) can be attached at any position on the front of the rail body (100). The electronic lathe label (70) can move left and right along the length direction of the rail body (100). Additionally, since a plurality of rail electrodes (230) are mounted in the electrode section (200) and extend along the length direction of the rail body (100), at least one pin (p1, p2, p3, p4) of the electronic lathe label (70) can be electrically connected to the electrode section (200) at any position on the rail body (100). The electronic lathe label (70) can be electrically connected to the electrode section (200) to receive power from the battery of the auxiliary device and drive, and can display information and update the displayed information under the control of the controller.

[0149] Additionally, when the electronic shelf label (70) is fastened onto the power rail (10), the array insertion protrusion (735) provided on the rear of the mounting vertical extension (733) can be inserted into the array hole (320). As the array insertion protrusion (735) is inserted into the array hole (320), the electronic shelf label (70) can be fixedly fastened onto the power rail (10).

[0150] The shelf fastening part (91) can be fastened to the power rail (10) for electronic shelf labels. The shelf fastening part (91) can be part of the shelf (90) of FIG. 2 and can be configured to be installed on the shelf (90) independently of the shelf (90).

[0151] The shelf fastening part (91) may include a shelf plate (910). When the power rail (10) is fastened to the shelf fastening part (91), a portion of the front surface of the shelf plate (910) may come into contact with the rear surface of the rear plate (121). A first shelf hook (920) may be formed in the upper end area of ​​the front surface of the shelf plate (910), protruding a predetermined distance in the forward direction from the shelf plate (910) and then protruding a predetermined distance in the upward direction. Additionally, a second shelf hook (930) may be formed in the lower area of ​​the bottom surface of the shelf plate (910), protruding a predetermined distance in the forward direction from the shelf plate (910).

[0152] When the power rail (10) is connected to the shelf connection part (91), the first shelf hook (920) is connected to the first connection latch part (133), and the second shelf hook (930) can be connected to the connection protrusion (163) while being inserted into the first space (103).

[0153] Meanwhile, a battery insertion opening (131h) may be formed in a portion of the upper plate (131) of the rail body (100). Through the battery insertion opening (131h), the battery can be inserted into the first storage groove (101). This battery provides power to the power rail (10), and the power rail (10) can provide driving power to the electronic shelf label (70) through the electrode portion (200). Thus, if necessary, an additional power supply device can be easily installed on the power rail (10).
