Abstract
An overhead projector includes an opening in its bottom to accommodate a pivoting mirror. This opening is closed by two doors which pivot to support the projector in use. The projector includes latches which retain the doors in the closed position and gravity cams which retain the doors in the open position, but which automatically release the doors when the projector is placed on its side.
