Abstract: A display apparatus (100) includes a shelf tag attachment member (102) being fixed to a front end surface of a product shelf S, and a shelf tag (101) having a display surface (103). The shelf tag (101) is attached to the shelf tag attachment member (102) via a rotation axis A, and is rotatable in a predetermined direction in which the display surface (103) is turned upward. A lower end of the shelf tag (101) is located below a lower surface LS of the product shelf S and a lower end of the shelf tag attachment member (102) in a vertical direction.

Abstract: A shelf tag attachment apparatus (100) includes an electronic shelf tag (101), and a shelf tag holding portion (103) for holding the electronic shelf tag (101). The electronic shelf tag (101) includes, on each of an upper end and a lower end, a groove portion (105) extending in a left-right direction, and the shelf tag holding portion (103) includes a protrusion portion (115) that projects downwards and upwards, and that fits into each of the upper groove portion (105) and a lower groove portion (105). At least one combination of a combination of the upper groove portion (105) and the protrusion portion (115) that fits into the groove portion (105), and a combination of the lower groove portion (105) and the protrusion portion (115) that fits into the groove portion (105) is discretely provided.

Abstract: A shelf tag attachment apparatus (100) includes a shelf tag holding portion (103) for holding an electronic shelf tag (101), and a support member (102) that supports the shelf tag holding portion rotatably about a rotation axis P extending in a left-right direction of the electronic shelf tag (101). The shelf tag holding portion (103) includes a bearing portion for rotating about the rotation axis P relative to the support member (102). The support member (102) includes an arm portion (110) that is provided with a shaft portion (112), and that sandwiches the bearing portion from the left-right direction. The shelf tag holding portion (103) includes a stopper (130) that contacts the arm portion (110), and thereby locks in such a way that a display surface (104) of the electronic shelf tag (101) does not rotate beyond a previously determined range in a direction to face downwards.
