发明名称 SCREEN DEVICE AND REAR PROJECTION TYPE IMAGE DISPLAY APPARATUS
摘要 <P>PROBLEM TO BE SOLVED: To provide a screen device that is less affected by the brightness of environment, capable of providing eye-friendly images even if an image projection device having low optical output is used, and is not obstructive when not used. <P>SOLUTION: The screen device includes: a screen 102 which transmits and diffuses image light from a rear side; a storage part 101 which rolls up and stores the screen 102; and a light-shielding member 111 which covers the screen 102 from the rear face such that a space through which image light traveling to the screen 102 passes is formed between the light-shielding member and the screen 102. The screen 102 is stretched by moving a second end portion, which faces a first end portion attached to the storage part 101, upward or downward so as to be separated from the storage part 101. On the other hand, in the light-shielding member 111, one end portion is attached to a member closer to the storage part 101 and the other end portion facing the one end portion is connected to the second end portion in the state of covering the screen 102 from behind. <P>COPYRIGHT: (C)2013,JPO&INPIT
