ABSTRACT:
A publication viewer for viewing sequential pages of a bound publication, printed on pages attached to a flexible strip of material. The pages include printed text pages and groups of animated pages of drawings or photographs. Indexing notches on the pages are either tagged or untagged so that printed text pages can be viewed for an extended period of time, while the groups of animated pages are viewed in quick succession. The viewer itself is a rectangular box including a rectangular opening with an open view portion for sequentially displaying pages of the publication, and a release button for continuing the advancement of the pages. The back of the box has a rectangular opening through which the publication is loaded into the viewer. A drive mechanism in the form of an AC or DC electrical motor, or a spring wound motor, is operatively connected to a first, bottom shaft. The first, bottom shaft and a second, top shaft are covered by a continuous loop of web material with hooks for engaging the flexible strip of material. As the shafts turn, the hooks in the web pull the drive bar, causing the pages to flip by the viewing window one at a time. An indexing system engages tagged pages so that printed text pages can be viewed long enough to read. The indexing system does not engage untagged pages thereby allowing high-speed sequential viewing of animated pages.
