Abstract
A device for displaying the names of items and their prices uses a generally planar panel that has pairs of parallel tracks on its rear side and parallel guide channels on its front side. There is an elongated aperture in the panel between each pair of tracks and guide channels. Strips bearing printed item names and other information are inserted in the channels. The strips have variable numbers of either apertured or transparent windows aligned with the aperture. A tape carrier for tapes bearing indicia such as numerals for composing prices that are displayed through the windows is engageable with the rear tracks by means of its inherent flexure property. Divider members engage the carrier with a snap action and they create channels in conjunction with the carrier surface for guiding and restraining the edges of the tapes against all but longitudinal movements.
