Abstract
PURPOSE:To enable watching and listening from the area of wide range by providing the screen of a transmission type to the side surfaces more than two and driving a CRT device to correspond to the respective screens according to a video signal processed by a common television signal processing circuit and projecting an image. CONSTITUTION:A ray projected from one the CRT device 11 is magnified through a magnifying lens 14, reflected by one surface 13a of a both surfaces mirror 13 and deflected in the direction of one side surface 10a of a device main body 10. A ray projected from the other side CRT device 12 is magnified through a magnifying lens 15, reflected by the other surface 13b of the both surfaces mirror 13 and deflected in the direction of a side surface 10b parallel to the side surface 10a. To the both side surfaces 10a and 10b respectively placed in parallel, screens 16a and 16b of transmission type are respectively arranged and through them, an image is projected. Thus, the area to be able to be watched and listened to can be greatly increased.
