Abstract
A binder, such as a three ring binder, is provided with a magnetizable panel on the front cover of the binder and with a stylus and a permanent magnet erasing device mounted onto the binder. The magnetizable panel may be inset into the cover of the binder, or it may constitute substantially the entire front cover of the binder, or it may be inserted into a transparent pocket on the front cover of the binder. The eraser may be of a broad area permanent magnet type which may be brought into engagement with the entire magnetizable panel; or a smaller linear permanently magnetized eraser may be employed.
Claims21
A binder assembly with a magnetizable write/erase cover comprising:
- a binder with front and rear covers and an intermediate spine;
- said covers being pivotally mounted with respect to one-another;
- a paper retention construction for releasably holding sheets of paper within said binder, mounted at said spine;
- at least one of said covers having a substantially flat magnetizable write/erase panel mounted thereon;
- said write/erase panel having inner and outer sheets, viscous material between said sheets, and particulate magnetic material dispersed in said viscous material;
- said outer sheet being translucent,
- a magnetic stylus for applying a magnetic force to said outer sheet to draw said particulate magnetic material to said translucent outer sheet to create an image;
- a magnetic eraser for application to said write/erase panel to erase any image appearing on said outer surface;
- said binder having retaining arrangements for mounting said magnetic stylus and said magnetic eraser onto said binder;
- and
- said magnetic stylus and said particulate material cooperating to produce line images on said panel following the path of said stylus on said magetizable panel, to permit the user to write messages and draw images on said magnetizable panel.
