ABSTRACT:
A writing device is disclosed wherein a clear overlay is pivotally attached to an underlying enclosure. A support surface is formed on the enclosure beneath the clear overlay. Paper forms may be placed on the support surface such that one may write on the clear overlay, using the written guide to trace. In another feature, the support surface is provided by a secondary writing surface that may be selectively positioned on the overlay. The secondary writing surface upon removal is dimensioned to be accepted within a well-like enclosure formed by the frame for the clear overlay. The secondary writing surface is erasable, may be formed of a porcelainized wallboard, and additionally may be magnetized. Alternatively, a chalkboard may be utilized for the secondary writing surface. The overlay is preferably formed of a non-porous coated plexiglass to make it being easily erasable. In addition, the overlay may be attached to the enclosure through a removable hinge such that it may be removed for cleaning. In additional features, a protective storage cover is placed over the overlay by a hook and loop-type fastener. Also, a drawer may be formed in the enclosure.
