Abstract
A video rear-screen projection apparatus includes a housing accommodating a fixedly arranged cathode-ray tube unit which is provided with a projection lens and which is secured to a frame. The apparatus also includes a first mirror pivotally connected to the housing so that the mirror can be located entirely inside the housing or can be extended with its reflecting surface facing the projection lens. The apparatus further includes a transparent screen which extends in the direction of width of the housing and is pivotally associated with a pivot on the frame, and also includes a second mirror pivotally associated with the housing. The screen and the two mirrors are arranged such that they can be extended so that the light rays from the cathode-ray tube strike the transparent screen or can be folded so that they are located inside the housing.
