The invention concerns a display device by unwinding a data medium screen (300), wherein the screen (300) is wound and unwound around two powered and synchronised rolls (100, 200) such that the screen (300) is maintained fully stretched out while it is being unwound. The invention is characterised in that: the upper end (310) of the screen (300) is mounted detachable on a fixing module (110) integral with the upper roll (100); the fixing module (110) is connected to the upper roll (100) by an unwinding mechanism (400) for moving the fixing module (110) near the lower roll, for mounting and dismounting the upper end (310) of the screen (300); it comprises means (500, 501, 340) for maintaining the screen fully stretched out.

Several image-holding panels, having running rollers at their upper corners, rest with the rollers upon parallel running tracks that are inclined from an input end to an output end. A transfer device, which may be a chain, collects the panel which arrives in turn by gravity to the output end of the magazine and transfers it to the input end of the same or of another magazine.
