Abstract
Abstract The invention permits a draftsman or student to carry needed materials conveniently for work at various locations and it also can be used to enable such a person to work at one location without investing the money and the space for a bulky drafting table. There is provided a case which encloses the above-mentioned needed materials and also contains a lid-support mechanism which locks at various positions. One exterior surface of the case is a drawing surface, and the lid-support mechanism permits it to be retained, when in use, at a desired angle with respect to the horizontal.
