Patent ID: 7798652

Claim:
A display shelf comprising: a plurality of placing tables for placing articles; a plurality of transmission-type screens which are positioned at front areas of the placing tables, and which transmit and project projector image luminous fluxes that are projected from back sides of the screens; an inner circumference defining a space including an image projecting space which leads the projector image luminous fluxes projected from the back sides of the screens to back surfaces of the screens without obstruction; a projector placing part on which a projector is placeable, wherein the projector is configured to project the projector image luminous fluxes; a plurality of reflecting mirrors which are placed in the image projecting space corresponding to the plurality of screens, and which reflect and lead the respective projector image luminous fluxes from the projector to the corresponding screens, wherein the projector placing part is arranged such that the projector image luminous fluxes to be projected are focused on the corresponding screens, and wherein each of the plurality of transmission-type screens is placed to have an optical distance from a standard surface of the projector such that the plural screens are placed at a projecting image surface in a reflecting and focusing system of the projector image luminous fluxes projectable from the projector; and a plurality of ceiling panels which are provided corresponding to the plurality of screens, and which are placed under corresponding horizontal image projecting areas so as to prevent the articles from entering into the corresponding horizontal image projecting areas.
