Abstract
A plurality of flexible strips are included in a changeable character display device. Each strip has a series of display portions that are longitudinally arranged on a strip. A guide panel of the device includes respective pairs of apertures arranged laterally in a row. Each respective pair of apertures is associated with a respective one of the flexible strips. Each flexible strip is arranged to have a viewable display portion situated between the individual ones of the associated pair of apertures whereby the respective displayed portions of the plurality of strips form lateral rows. The non-displayed portions of the respective flexible strips extend rearwardly through the associated pair of apertures. A guide channel member includes a laterally-extending channel that receives the non-displayed portions of the flexible strips and clusters them together in a lateral direction. A further row of characters which are vertically spaced from the first row may be included in the display device while being closely spaced to the first row. Rapid and accurate changing of the characters of each flexible strip is facilitated by alignment apertures in the flexible strip situated between adjacent display portions on the strip.
