Abstract
A screen unit includes a flexible screen, a pantograph mechanism which expands and stores the screen, a motor which shifts one end of the pantograph mechanism to stretch and contract the pantograph mechanism, and a wire. The screen unit further includes a housing which accommodates these components, and a cover which opens and closes at the time of expansion and storage of the screen. One end of the wire is held by the electric motor, and the other end of the wire is held by the cover, so that the cover can be closed in accordance with the contraction of the pantograph mechanism effected by the motor.
