(57) The invention relates to a publicity board generally having trilateral prisms which are situated with their edges against each other, which position is repeated after each rotation over 120°. To prevent friction and shocking, due to play between the moving parts, the driving member has a coupling member (18), which let the driven member rotate around his axis (3) bringing the driven member in engagement with a segment (17) of the drive member, such that almost no slip between said parts occurs and that a very smooth operation is obtained. By this a self-driving alternating-current motor can be used.
