PURPOSE: A 4-way-hanging portable screen device having a folder member is provided to improve portability by varying a volume of a screen device to a miniature, and to improve usability by developing four ways at the same time. CONSTITUTION: A 4-way-hanging portable screen device (1) having a folder member comprises a screen-film (10), a pair of fixed frames (20), an upper folding member (30), and a lower folding member (40). The screen-film is folded or developed in order to vary a plane of incidence, and an image projected on one side is projected onto. A pair of fixed frames is connected to both sides of the screen-film, and develops horizontally. A pair of fixed frames comprises an upper connecting piece (21) and a lower connecting piece (22) in an upper part and a lower part of an inner side. The upper folding member is connected by multiple hinges in order to be folded horizontally by connecting to the upper connecting piece. The upper folding member comprises an upper folding arm (31) and multiple upper vertical arms (32). The lower folding member is connected by multiple hinges in order to be folded horizontally by connecting to the lower connecting piece. The lower folding member comprises a lower folding arm (41) and multiple lower vertical arms (42). |
