   Anwendungsgebiet sind scheibenförmige Bildträger zur Betrachtung gerahmter Diapositive. Soweit solche Bildträger bekannt sind, ist an deren Schaltzeit keine besondere Bedingung geknüpft. Zur Erreichung gleichmässiger, praktisch nahtloser Bildübergänge, ist eine besonders kurze Schaltzeit erforderlich, die erfindungsgemäss, mit Hilfe von Magnetfeldern, indem je ein permanenter Pol im Bildträger für jede Bildstelle, ein polwechselbarer Magnet, der die Aufgabe hat, mit dem nächstbefindlichen Permanentpol ein Magnetfeld zu bilden, das den Bildträger lagefixiert, sowie für jede Drehrichtung einen weiteren polwechselbaren Magnet, flankierend zum ersten, mit diesem wahlweise zu einem an sich bekannten Schaltfolgeprogramm gepaart, den Bildträger um eine Bildstelle verdrehen, vorgesehen sind.

   Ein Ausführungsbeispiel des Erfindungsgegenstandes in in der Zeichnung dargestellt, und zeigt : 
 EMI1.1 
 aufgebaut, dreht sich der Bildträger im Uhrzeigersinn eine halbe Bildstelle weiter. Wird dieses Feld   von--S--     nach --3-- verlagert,   wandert der Bildträger nochmal eine halbe Bildstelle weiter und verharrt so lange, als das Feld von   Magnet --3-- aufrechterhalten   wird. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

   Field of application are disc-shaped image carriers for viewing framed slides. As far as such image carriers are known, no special condition is attached to their switching time. In order to achieve even, practically seamless image transitions, a particularly short switching time is required, which according to the invention, with the help of magnetic fields, by adding a permanent pole in the image carrier for each image area, a pole-changeable magnet, which has the task of creating a magnetic field with the next permanent pole form, which fixes the image carrier in position, and for each direction of rotation a further pole-changeable magnet, flanking the first, paired with this optionally to a known switching sequence program, rotating the image carrier by one image point, are provided.

   An embodiment of the subject matter of the invention is shown in the drawing and shows:
 EMI1.1
 assembled, the image carrier rotates clockwise half an image area. If this field is shifted from - S-- to --3--, the image carrier moves another half image area further and remains as long as the field of magnet --3-- is maintained.

** WARNING ** End of DESC field may overlap beginning of CLMS **.
