Abstract
Abstract In a price display board self-coiling plastic tapes having a sequence of numerals imprinted on them are translatable past rows of windows. Tape holders behind the windows have platens for supporting the tapes from their rear faces. The platens have one edge molded integrally with the holders and three free edges so they can act as preflexed flat springs for pressing the tapes against tape guide flanges which extend along the sides of the windows.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
160 words
A device for displaying characters to compose descriptions such as prices including self-coiling plastic tapes on which the characters are imprinted in sequences extending longitudinally of the respective tapes, said device comprising: means providing a pair of longitudinally spaced apart edges and a pair of laterally spaced apart edges cooperating to define a window past which a tape may be translated to expose its characters for visualization from the front surface of the tape, a flange extending along each of the edges of at least one pair of window edges for the front surface of said tape to react against, a tape support composed of plastic located behind the window and a platen element located behind said window, said platen element being joined integrally with said support and extending in cantilever fashion across a major portion of the window and having an inherent tendency to flex toward the front of said window to thereby press said tape against said flanges.
