ABSTRACT:
A lockable storage cart for an overhead projector and a calculator viewscreen for a graphics calculator viewscreen for a graphics calculator has a flat top surface with an opening to permit entry of the projector and viewscreen which rest on a flat bottom surface. The vertical arm and reflector of the overhead projector extend above the top surface to project an image from the calculator viewscreen and/or overhead projector onto a projection screen. A cover closely fits the opening in the top surface and is lockable, so as to prevent unauthorized removal of the contents of the cart. The sides of the cart are made of wire mesh to allow free flow of cooling air and the cart is provided with legs and casters to allow ready movement. Alternatively, the legs and casters may be removed and the cart permanently installed by straddling spaced-apart desks or tables.
