Abstract

A rear illuminated device for displaying prices of articles is of the type that includes a housing, a light source in the rear of the housing, a front frame mounted on the housing which has a plurality of horizontal rows of windows, each of said windows being adapted to display one rear illuminated numeral of the price of an article, a film strip carrier in closely spaced cooperating relationship with each window, and each said carrier cooperating with the front frame to define a guide slot in which a section of a film strip is held effectively flat in the window, and a film strip supported on each carrier for endwise movement through a guide slot, each section of a film strip being adapted to display one of the numerals from 1 through 0 in the window. Each film strip is a continuous loop which loosely encircles the film strip carrier and is positioned entirely forward of the light source in the housing, and adjacent film strip loops are in side abutting relationship so as to be mutually confining. Each film strip carrier has a transverse slot centered between the lateral sides of a window immediately adjacent and parallel to a transverse margin of the window, and indexing holes in each film strip are aligned with a slot and so associated with the film strip sections that when a hole is moved from one end of a slot to the other it moves the film strip by one section and centers a section in the window.
