Abstract (en)
[origin: WO2013160573A1] The invention relates to a screen device (10) having a casing (11), a projection screen (12) and a setting (13) associated with displacement means (20) for modifying the visible content of the casing. It is characterized in that the projection screen (12) and the setting (13) are combined on a unitary support sheet (14) and said displacement means (20) comprise two parallel winding rollers (21, 22), about which said support sheet (14) is wound, one of these rollers being a motorized driving roller. It furthermore comprises stiffening means (50) associated with the two free edges (14a) of said support sheet (14) in order to stiffen them in the winding direction of said sheet and to confer perfect flatness on said sheet over its entire surface area, and also guide means (60) for said free edges (14a) of the support sheet (14), which are associated with the stiffening means (50).
