Bei der Anordnung nach F i g. 3 sind die einzelnen Taschen 2 bei 31 zu einer buchähnlichen Kassette 32 zusammengefaßt, die als Ganzes im Magazin 3 untergebracht ist. Die Taschen 2 mit dem Schlitz 9 entsprechen im wesentlichen den Taschen bei der Anordnung nach F i g. 1 mit dem Unterschied, daß die einzelnen Taschen durch nicht dargestellte harmonikaartige Balgen miteinander verbunden sind, wodurch, wie später gezeigt wird, das Aufnehmen der abgespielten Folien erleichtert wird.In the arrangement according to FIG. 3 are the individual pockets 2 at 31 to form a book-like cassette 32 summarized, which is housed in the magazine 3 as a whole. The pockets 2 with the slot 9 correspond essentially the pockets in the arrangement according to FIG. 1 with the difference that the individual pockets are connected to one another by concertina-like bellows, not shown, whereby, as will be shown later, it makes it easier to record the slides being played.

Beim Folienwechsel bringen die Reibräder 10 und 12 die abzuspielende Folie wieder auf den Mitnehmer?, von wo sie nach dem Abspielen mittels des Reibrades 19 in eine geöffnet liegende Tasche der leeren Buchkassette 34 transportiert wird. Die balgenartige seitliche Verbindung der einzelnen Taschen sorgt dafür, daß die Folien nicht seitlich aus den Taschen herausrutschen. Sie gibt ferner der ganzen Kassette einen gewissen Halt und gestattet das Aufblättern der Kassette durch das Eigengewicht, um eine jeweils freie Tasche an die Stelle des Abtransports zu bringen.When the film is changed, the friction wheels 10 and 12 bring the film to be played back onto the driver? from where after playing by means of the friction wheel 19 in an open pocket of the empty book cassette 34 is transported. The bellows-like side connection of the individual pockets ensures that the foils do not slip out of the pockets. It also gives the entire cassette a certain hold and allows it to be opened the cassette by its own weight, in order to have a free pocket at the point of removal bring.

Um dieses Aufblättern zu ermöglichen, sind, wie Fig. 3,4 und5 deutlicher erkennen lassen, die einzelnen Taschen 2 mit beidseitig angeordneten, bei aufeinanderliegenden Taschen jeweils versetzten Lappen 35 und 36 versehen, die jeweils auf einem in den gezeichneten Pfeilrichtungen verschiebbaren Schieber 37 ruhen. Je nach der Stellung des Schiebers, der selbsttätig beim Abspielen gesteuert wird, liegt entweder der Lappen 35 mit der zugehörigen und den darüberliegenden Taschen oder entsprechend der Lappen 36 auf dem Ansatz 38 des Schiebers 37 auf. Es ergibt sich dann die Lage der Taschen, wie sie in F i g. 3 auf der linken Seite dargestellt ist. Die beiden Schieber 37 sind im Gehäuse 39 gelagert und werden im Rhythmus des Folienwechsels gesteuert.In order to enable this leafing out, as can be seen more clearly in FIGS. 3, 4 and 5, the individual elements Pockets 2 with arranged on both sides, offset in each case when the pockets lie on top of one another Flaps 35 and 36 are provided, each of which can be displaced on one in the arrow directions shown Slide 37 is at rest. Depending on the position of the slide, which is controlled automatically when playing, either the tab 35 with the associated and the overlying pockets or, correspondingly, the tabs 36 on the extension 38 of the slider 37 on. The position of the pockets then results, as shown in FIG. 3 shown on the left is. The two slides 37 are mounted in the housing 39 and are in the rhythm of the film change controlled.

An Stelle der Taschen können auch einfache an einer Seite festgelegte Zwischenlagen vorgesehen sein, was allerdings nicht ohne weiteres das selbsttätige Einlegen der abgespielten Folien ermöglicht.Instead of the pockets, simple intermediate layers fixed on one side can also be provided which, however, does not allow the automatic insertion of the played foils.

ao Es sei noch bemerkt, daß die Taschen und das Buch neutral — nicht mit einem Titel ■— beschriftet sein müssen.ao It should also be noted that the pockets and the book are neutrally labeled - not with a title ■ must be.
