Display shelf and display shelf system

Abstract

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.
