According to one embodiment, a commodity information browsing system includes a shelf label apparatus including a first storing section and a first transmitting section, a portable terminal including a first receiving section, a notifying section, a second receiving section, and a display section, and a server apparatus including a second storing section and a second transmitting section. The first transmitting section transmits, by radio, one shelf label code among a plurality of shelf label codes. The notifying section notifies the server apparatus of the shelf label code. The second storing section stores association information representing a relation between the shelf label codes and commodity information. The second transmitting section determines, on the basis of the association information, the commodity information associated with the notified shelf label code and transmits the relevant commodity information to the portable terminal. The display section displays an image based on the commodity information.

A wireless communication system, comprises a tower-shaped antenna includes a leaky coaxial cable that leaks a radio wave and a reflective member that reflect the radio wave leaked from the leaky coaxial cable in the direction perpendicular to an axial direction of the leaky coaxial cable.

Wireless communication system

According to one embodiment, an antenna apparatus includes a leaky coaxial cable and a power supply apparatus. The power supply apparatus that provides a voltage for operating a mobile terminal receiving a radio wave radiated from the leaky coaxial cable when a high-frequency signal is provided.

Antenna apparatus and wireless communication apparatus

A display shelf system includes a display shelf, which includes a plurality of placing tables which are adapted to have an article placed thereon. A plurality of transmission-type screens are arranged with the placing tables, respectively. A projector projects a projector image, and a light guide of the display shelf leads the projector image onto the rear sides of the transmission-type screens. The transmission-type screens have curved surfaces which are inclined to face toward a lateral direction with respect to a front of the display shelf, so that the transmission-type screens are easily viewable by viewers who are in the lateral directions of the display shelf.

Screens are positioned at front areas of respective placing tables which form placing spaces for placing an article. Each of the screens is a transmission-type screen capable of transmitting projection image light projected on a back side of the screen. A first optical system and a second optical system are arranged inside the display shelf. The first optical system leads first partial image light, which is included in projection image light projected from a projector in the display shelf, to the back sides of the screens. And the second optical system leads second partial image light, which is included in the projection image light, to at least one of the placing spaces.

When obtaining an ID code from a user who holds out an arm to a corresponding merchandise in a noncontact manner, respective information terminal devices accept a registration input of the corresponding merchandise. When accepting the registration input of the corresponding merchandise, registration merchandise information including obtained user identification information and merchandise identification information for identifying the merchandise corresponding to the information terminal device is transmitted to a server device. The server device stores and manages merchandise sales information for the respective ID codes from the registration merchandise information received from the respective information terminal devices. When the ID code is input from a settlement device, the merchandise sales information corresponding to the ID code is transmitted to the settlement device. The settlement device performs the settlement processing based on the merchandise sales information received from the server device.

Merchandise registration processing system

An image display controller for a display shelf generates image data for a projector image which is projected by a projector arranged in the display shelf to be displayed on a transmission-type screen of the display shelf. The image display controller includes a monitor, an input device, a data communicator, a memory, and a controller. The controller obtains an editing background image from the memory and displays the editing background image on the monitor, and generates contents of a display image. Moreover, the controller sets a position of the generated display image in a desired position of a display area of the editing background image in response to an instruction inputted via the input device, and generates the projector image by combining the generated display image into the editing background image at the set position.

Image display controller for display shelf

Transmission-type screens are placed corresponding to a display board at a front area of the display board, on which an article is placed. Each of the screens transmits and projects a projector image luminous flux projected from a backside of the screens to a front side of the screens. When the projector image luminous flux is projected from the backside of the screens, each of inner circumferences which defines a space including an image projecting space for leading the projector image luminous flux to the backside of the screens without obstruction. A display shelf might have a projector and a computer. The projector projects the projector image luminous flux. The display shelf might have a reflecting mirror which lead the projector image flux to the screens.
