| 摘要 |
The invention concerns a multipurpose advertisement device, with a carrier frame (1) comprising one or more border parts (2, 2') with an information carrying outer surface (2c) and with a primary information carrying means (4) for the displaying of characters and/or figures and/or other symbols for attracting attention. The primary information carrying means (4) have magnetic first connecting means (4a). Within the device there is a movable, rotating second connecting means (5b), with an attracting magnetic force between the first and second connecting means (4a, 5b). The primary information carrying means (4) is movably positioned on the outer surface (2a) of the device, and the second connecting means (5b) is positioned within the device in the proximity of the first connecting means (4a). The magnetic force is great enough for the primary information carrying means (4) to be attached to the surface of the information carrying outer surface (2c) of the carrier frame (1) and to be kept in place only by the attracting magnetic force acting between the first connecting means (4) and the second connecting means (5b) and by the frictional forces arising from said magnetic force.
