PURPOSE:To easily watch images in a free posture by providing a light source and an original image device on a frame which can be set to reset from a bed and opposing them to a movable screen. CONSTITUTION:When a patient 3 lying on a bed 2 in a sickroom wants to watch desirable images of a television, he operates a screw 8 with a single hand in a lying posture so as to specifically incline the frame 9 of an image display device 12 in a vertical surface and rotate it up and down with respect to a pole 6. By operating the dial 11, etc., of the projecting device 12 with a single hand, a halogen lamp 20 is lighted and a driving device 26 switches a channel to desirable one, then the original image of the television can be formed on a color liquid crystal panel 25. Light from the halogen lamp 20 is transmitted through a heat ray absorption filter 22 and a polarization panel 23, stopped down a by Fresnel lens 24, passes through the original image on the liquid crystal panel 25, and is projected by a projecting lens 27, so that a high definition color image which is enlarged on a stereoscopic screen 13 can be projected. Thus, the patient can be watch the images of the television in a desirable state. |
