PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung bezieht sich auf eine Anlage, welche gestattet, Vergrößerungen photographischer Panoramaansichten, die einen Umkreis von bis 360 ° umfassen können, zu erhalten, die weder Unterbrechungs- noch Verbindungsstellen aufweisen. Sie beruht auf der Anwendung eines an sich bekannten, Objektiv, Sammellinse und Lichtquelle aufweisenden, sich um eine die horizontale Objektivachse kreuzende Vertikalachse drehenden Projektionsapparates, welcher das Bild eines feststehenden, eine Panoramaansicht aufweisenden photographischen Bildträgers auf einen konzentrisch zur vertikalen Drehachse des Projek-The present invention relates to a system which allows photographic enlargements Panoramic views that can encompass a radius of up to 360 ° are obtained, which have neither interruptions nor connection points exhibit. It is based on the application of a known lens, converging lens and light source, a projection apparatus rotating around a vertical axis that crosses the horizontal lens axis, which the image of a fixed, a panoramic view exhibiting photographic image carrier on a concentric to the vertical axis of rotation of the project

Während bei dem bekannten Projektionsapparat die vertikale Drehachse durch die Lichtquelle gelegt ist, geht bei der neuen Anlage die vertikale Drehachse durch das Objektiv, so daß Ablenkungsprismen und Spiegel, die bisher notwendigerweise zwischen Lichtquelle und Sammellinse eingeschaltet werden mußten, in Fortfall kommen.! 5 projection apparatus arranged screen is projected. While in the known projection apparatus, the vertical axis of rotation through the light source is placed, the vertical axis of rotation goes through the lens in the new system, so that deflection prisms and mirrors, previously necessarily between light source and the converging lens had to be switched on, in failure.
Ein Ausführungsbeispiel der Anlage ist in Fig. ι schematisch im Horizontalschnitt und in Fig. 2 in vergrößertem Vertikalschnitt teilweise zur Darstellung gebracht. In dieser Zeichnung ist die Vorrichtung zum Bewegen des Projektionsapparates nicht zur Darstellung gebracht, da die Bewegung desselben auf verschiedene Weisen erhältlich ist.An embodiment of the system is shown in Fig. Ι schematically in horizontal section and in Fig. 2 partially shown in an enlarged vertical section. In this Drawing is the device for moving the projection apparatus not for illustration brought because its movement is available in different ways.
Auf einem Träger α befindet sich eine runde Platte b, die um ihre Achse gedreht werden kann, und zwar z. B. mittels einer Handkurbel, eines Uhrwerks o. dgl. Auf dieser Platte befindet sich ein Objektiv c, eine Sammellinse d, eine Lichtquelle e und ein Reflektor f. Das zu vergrößernde Filmnegativ ist auf einem feststehenden Träger g befestigt, der konzentrisch zum Objektiv zwischen diesem letzteren und der Sammellinse d angeordnet ist. Die lichtempfindliche Fläche, welche das vergrößerte Bild aufnehmen soll, befindet sich auf dem konzentrisch zur Platte b angeordneten, feststehenden Träger h. On a carrier α there is a round plate b, which can be rotated about its axis, namely z. B. by means of a hand crank, a clockwork o. The like. On this plate there is a lens c, a collecting lens d, a light source e and a reflector f. The film negative to be enlarged is mounted on a fixed support g , which is concentric to the lens between this latter and the converging lens d is arranged. The photosensitive surface, which is to receive the enlarged image, is located on the stationary support h which is arranged concentrically to the plate b.
Während die Platte b eine Teilumdrehung vollzieht, wird das auf dem Träger g angebrachte Bild vergrößert auf die lichtempfindliche Fläche von h geworfen.While the plate b completes a partial revolution, the image attached to the carrier g is projected enlarged onto the photosensitive surface of h .
