In der F-Lgur 1 -ist tritt 1 das Gehäuse etnes Projektors bezeichnet, tei dessen Inneren steh in an sicL benannter Weise eine Lampe 2 und eine KandensarZinse 3 befindet. In einen Schacht 4 ist ein ein Diapositiv 5 hatte ruder Rahmen 6 verschiebZich so einbriii.9bar, daß das Diapositiv &ngr;&sgr;&tgr;&eegr; Licht der Lampe 2 durchleuchtet wird. In einem mit einem Gewinde versehenem Tubus 7 befindet sich das Objektiv de&ogr; Projetitars, dessen optische Achse & mit der der Kondensor- tinse 3 zusammen^ätZt und au teil die Mitte des Dtaposttives 5 verÄäujyt, wenn dieses in den cchacht 4 eingebracht ist. Durch Drehen des Tubus 7 kann die Scharbe des au^ die in der Figur nicht dargestellten Bildt^Zäche projtzierten Bildes eingestellt werden. In the figure 1, 1 is the housing of a projector, inside of which there is a lamp 2 and a condenser lens 3 in the manner described above. A slide 5 can be slidably inserted into a shaft 4 via a frame 6 so that the slide is illuminated by the light of the lamp 2. The projector lens is located in a threaded tube 7 , the optical axis of which coincides with that of the condenser lens 3 and partially covers the center of the projector lens 5 when the latter is inserted into the shaft 4. By rotating the tube 7, the size of the image projected onto the image surface not shown in the figure can be adjusted.
Im oberen Teil, des Projektors 1 ist dei Antrieb ^Ur eine trapezförmige Lochbtenden 9 in regelmäßigem Abstand aufweisende Scheibe IO angeordnet, welche mittels einer Nabe 11 au4i cM.e um <^e Achse 12 rotierende Antriebswelle J 3 aufsteckbar und damit leicht austauschbar ist. Der Antrieb ijiir die rotierende Scheibe 10 besteht vorzugsweise in einem Elektromotor, welcher über ein Getriebe mit der (uelle 13 gekupptlt ist, so daß verhältnismäßig kleine Drehzahlen 4yür die Scheibe 10 realisierbar sind. In the upper part of the projector 1, the drive is arranged for a trapezoidal disk 10 with perforated ends 9 at regular intervals, which can be attached to a drive shaft J3 rotating about an axis 12 by means of a hub 11 and is thus easily exchangeable. The drive for the rotating disk 10 preferably consists of an electric motor which is coupled to the shaft 13 via a gear, so that relatively low speeds for the disk 10 can be achieved.

Um bet de<\ Antmatton des Musters des Dlapaottlvs, nämltch bei meinst Szüiegung Übe &igr; alt älid^läche, eine Veränderung der originalen Struktur zu vermelden, sollten die benachbarten, unterschiedliche Helligkeiten aufweisenden Tell^lächen de y Husters deckungsgleich ausgebildet sein. Bezüglich Stel^enraster zeigt Figur 2 eine Aus^dhrungs■darm, welche In Ver bindung mit der In Figur J dargestellten Art de &igr; Lachblenden einen besonders guten Animationse^ekt ergibt. Das Dia positiv 5 weist ein Raster au^, bei dem In Gebrauchsteilung die Grenzlinien zwischen seinen hellen und dunklen Flächen auf) die Drehachse der Antriebswelle 13 ^Ur die Lochblendenschelbe 10 ausgerichtet sind. The brick dimensions/muds and the like to be used in accordance with the invention are suitable for all types of design, including stem, mile, gill or dot patterns . In order to indicate a change in the original structure when applying the pattern of the lapaottlv, namely when applying it to the old surface, the neighbouring surfaces of the y Huster, which have different brightnesses, should be designed to be congruent. With regard to the grid of the columns, Figure 2 shows a design which, in conjunction with the type of screen shown in Figure J, produces a particularly good animation effect. The positive slide 5 has a grid in which the boundary lines between its light and dark areas are aligned with the axis of rotation of the drive shaft 13 and the pinhole diaphragm plate 10.

Es Ist eine mittels eine &igr; Rändelschelbe 15 bewegbare Gewlndewetle 16 vorgesehen, welcher an Ihren beiden Enden jeweils ein Im Gehäuse des Projektars 1 bezw. 1' befestigter, drehbeweglicher Bolzen 17 mit einem Muttergewinde zugeordnet Ist, Mit dieser Verstelleinrichtung laßt sich cu^ einfache Uiel4>e der Winkel zwischen den optischen Achsen S und 8' justieren, das heißt, dem jeweiligen Abstand zwischen den Projektaren und der Bildfläche anpassen. Bei der Anordnung gemäß Figur 3 können entweder wie dargestellt beide Projektoren mit Lrchblendenschelben 10 bezw. 10' versehen sein, wodurch sich ein doppelter Animationsefäekt ergibt, oder Figure 3 shows two projectors 1 and 1' which are linked together by means of pivot plates 14. Their optical axes S and S ' are inclined towards one another and intersect on the image surface shown below. A threaded disk 16 which can be moved by means of a knurled disk 15 is provided, to which a rotatable bolt 17 with a nut thread is attached at each of its ends and is fastened in the housing of the projector 1 or 1'. This adjustment device can be used to easily adjust the angle between the optical axes S and S', that is to say to adapt it to the respective distance between the projectors and the image surface. In the arrangement according to Figure 3, both projectors can either be fitted with aperture plates 10 or 11 as shown. 10', which results in a double animation effect, or
