Claim 1
Independent Claim
145 words
A module for presenting alpha-numeric information comprising a frame, a plurality of shutter elements mounted on said frame and arranged in rows and columns to define an alpha-numeric module, a plurality of said modules being arranged in horizontal side-by-side relation with the shutters thereof positioned on the front of each module, illuminating means positioned behind the module arrangement, and means associated with each element for pivoting the shutter thereof to provide a part of a preselected piece of information, said means including an electromagnet, a permanent magnet on each shutter and actuating means remote from said module for actuating said electromagnet, each electromagnet being mounted on the front of said frame adjacent its associated shutter and equipped with pole-pieces arranged in close proximity to the permanent magnet of said associated shutter to oppose the magnetic field of said permanent magnet and pivot said associated shutter.
