KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung bezieht sich auf eine Vorrichtung zum Fortschalten und Belichten eines Bildbandes für die Aufnahme, Wiedergabe oder Vervielfältigung von Photoreihenbildern. Die bekannten, dem gleichen Zweck dienenden Vorrichtungen arbeiten mit einem komplizierten Mechanismus getrennt voneinander. Zur Vereinfachung hat man schon vorgeschlagen, den Verschluß und den zur Bandschaltung dienenden Schläger zu einem Stück zu verbinden.The invention relates to a device for switching and exposing a Photo book for the recording, reproduction or duplication of photo series images. The known devices serving the same purpose work with a complicated one Mechanism separate from each other. To simplify matters, it has already been suggested to connect the clasp and the racket used for band switching into one piece.
Von dieser Anordnung unterscheidet sich die Erfindung dadurch, daß die absatzweise Fortschaltung des Bildbandes durch Stifte, welche am Umfang der Trommel eines Verschlußzylinders angeordnet sind, bewerkstelligt wird, so daß der Transport des Bildbandes und die Absperrung des Lichtweges leicht und geräuschlos vonstatten gehen und eine ungleichmäßige Arbeitsweise ausgeschlossen ist. Verschlußzylinder, die nicht gleichzeitig Fortschaltorgane sind, haben bei Kinematographen schon Anwendung gefunden.From this arrangement, the invention differs in that the intermittent Continuation of the illustrated book by pins, which are on the circumference of the drum of a lock cylinder are arranged, is accomplished so that the transport of the picture tape and the blocking of the light path easily and proceed noiselessly and an uneven working method is excluded. Lock cylinders, which are not at the same time indexing organs, have in cinematographs already found application.
Die Erfindung soll an Hand der Fig. ι bis 3 näher beschrieben werden.The invention will be described in more detail with reference to FIGS.
Fig. ι zeigt die Schnittansicht einer Trommel mit einer Transport- und Abblendevorrichtung mit geöffnetem Verschlußzylinder, während Fig. 2 die gleiche Trommel bei Beginn des Transportes mit gesperrtem Verschlußzylinder darstellt.Fig. Ι shows the sectional view of a drum with a transport and masking device with the lock cylinder open, while Fig. 2 shows the same drum at the beginning of the Represents transport with locked lock cylinder.
Fig. 3 veranschaulicht die bildliche Ansicht der Vorrichtung von der Objektivseite.3 illustrates the pictorial view of the device from the objective side.
Durch die Mitte eines trommelartigen Gehäuses α führen die Lichtöffnungen b und b1, welche sich im Mittelpunkt der Trommel a rechtwinklig schneiden und je nach der Lage der Trommel den Lichtweg vom Objektiv d zum Bildband oder Platte e sperren oder freigeben. Am Umfang der Trommel befinden sich die Stifte c, welche für die absatzweise Fortschaltung des Bildbandes e bestimmt sind.The light openings b and b 1 lead through the center of a drum-like housing α , which intersect at right angles in the center of the drum a and, depending on the position of the drum, block or release the light path from the lens d to the photo book or plate e. On the circumference of the drum are the pins c, which are intended for the intermittent progression of the illustrated book e .
Die Vorrichtung kann mit mehr als zwei Lichtkanälen je nach Größe der Trommel versehen werden.The device can be provided with more than two light channels depending on the size of the drum will.
