Description
fine Vorsaizeinriclitung 7 zur Projektion von Dias gefestigt, die eine Linse 8 und ein Objektiv 9 aufweist, zwischen denen sich ein Dia-Schieber 10 (genauer gezeigt in Fig. 2) befindet, der durch einen Filmstreifenhalter Il (vgl. Fig. 3) ersetzt werden lean:1., nachdem der Dia-Schieber 10 herausgezogen ist.fine Vorsaizeinriclitung 7 for the projection of slides, which has a lens 8 and an objective 9, between which there is a slide slide 10 (shown in more detail in Fig. 2), which is replaced by a film strip holder II (see. Fig. 3) become lean: 1. after the slide slide 10 has been pulled out.
Das das Objektiv 9 verlassende Licht gelangt auf tine nicht abgebildete Projektionsleinwand.The light leaving the lens 9 reaches a projection screen, not shown.
Aus F i g. 2, die die erfindungsgemäße Vorsatztinrichtung 7 mit dem Dia-Schieber 10 in perspektivischer Ansicht zeigt, ist ein an der Oberkante der Vorsatzeinrichtung 7 angebrachter Einhiingesiifi 12 (vßl auch Fig. 1) ersichtlich, der m eine (nicht gezeigte) öffnung des Objektivgehäuses eingreift, woKm die Vorsatzeinrichtung 7 auf der zum Einliangestiii P entgegengesetzten Kante durch eine Rändelschraube 13 (vgl. Fig. 1) oder Rastfeder (nicht abgebildet) am Objektivgehäuse gesichert wird.From Fig. 2, the attachment device according to the invention 7 shows a perspective view with the slide slider 10, is a at the top of FIG Attachment device 7 attached mounting frame 12 (Vßl also Fig. 1) can be seen, the ma (not shown) opening of the lens housing engages, woKm the attachment 7 on the to Einliangestiii P opposite edge by means of a knurled screw 13 (see Fig. 1) or detent spring (not shown) secured to the lens housing.
Durch die erfindungsgemäße Vorsatzeinrichtung 7 zur Projektion von Dias und Filmstreifen können also Schreibprojektoren schnell von normalem Betrieb auf die Projektion von Dias oder Filmstreifen umgerüstet werden und umgekehrt.The front-end device 7 according to the invention for projecting slides and film strips can therefore Writing projectors quickly converted from normal operation to projecting slides or film strips and vice versa.
