Description

Gegenstand des Patents 72o 9o2 ist eine Zeigevorrichtung zum räumlichen Abtasten stereoskopischer Projektionsbilder mit dem Kennzeichen, daß die Vorrichtung auf dem Projektionsschirm zwei Lichtmarken erzeugt, die zueinander waagerecht verschiebbar sind und durch die gleichen Mittel wie die stereoskopischen Teilbilder den Augen zugeordnet werden. Die im Patent 72o 9o2 angegebene Ausführung der Lichtmarke in Form eines Pfeiles gibt zu Störungen Anlaß, wenn die Zeigevorrichtung als Handprojektionsgerät ausgebildet ist und der Lichtpfeil in die Ebene des Projektionsschirmes fällt. In diesem Fall hat der das Handprojektionsgerät Bedienende vielfach den Wunsch, den interessierenden Gegenstand des betreffenden Bildes von verschiedenen Seiten her anzuzeigen, d. h. also nicht nur von unten, sondern auch von oben, rechts oder links her. Zu diesem Zweck müßte das Projektionsgerät um seine Längsachse gedreht werden, wodurch bei im Projektionsgerät fest angeordneten Marken Höhenparallaxen der projizierten Einzelmarken auftreten.The subject of patent 72o 9o2 is a pointing device for spatial Scanning stereoscopic projection images identified as having the device Generated two light marks on the projection screen, which can be moved horizontally to each other are and by the same means as the stereoscopic partial images the eyes be assigned. The design of the light mark in The shape of an arrow gives rise to interference when the pointing device is used as a handheld projection device is formed and the light arrow falls in the plane of the projection screen. In In this case, the operator of the hand-held projection device often has the desire, the object of interest of the picture in question from different angles to display, d. H. so not only from below, but also from above, right or left here. For this purpose, the projection device would have to be rotated around its longitudinal axis, whereby in the case of marks fixedly arranged in the projection device, height parallaxes of the projected ones Single brands occur.

Zur Vermeidung dieses Nachteils ist im Patent 720 go2 bereits vorgeschlagen worden, die als Pfeil ausgebildeten Marken des Handprojektionsgerätes in einer Fassung drehbar anzuordnen bei solcher Schwerpunktslage des drehbaren Teiles, daß bei Verdrehung des Projektionsgerätes die Pfeile immer in derselben Lage bleiben.To avoid this disadvantage, it has already been proposed in patent 720 go2 to arrange the marks of the hand-held projection device in the form of arrows in a rotatable manner with the center of gravity of the rotatable part in such a way that the arrows always remain in the same position when the projection device is rotated.

Die Erfindung-geht einen anderen Weg zur Vermeidung des genannten Nachteils. Die Erfindung besteht darin, daß die Originallichtmarke bzw. die Marken je in einer von Hand aus drehbaren Fassung gelagert sind.The invention takes a different approach to avoiding the above Disadvantage. The invention consists in that the original light mark or marks are each stored in a rotatable version by hand.

Durch die drehbare Lagerung der Originalmarke bzw. Marken ergibt sich die Möglichkeit, den Lichtmarken jede gewünschte Richtung zu erteilen, d. h.,den interessierenden Gegenstand des betreffenden Bildes von verschiedenen Seiten her anzeigen zu können, nämlich von oben oder unten, rechts oder links, ohne daß Höhenparallaxen auftreten. Bei Vorhandensein zweier Originalmarken werden diese zweckmäßig durch einen gemeinsamen Antrieb gleichsinnig gedreht.The rotatable mounting of the original brand or brands results the possibility of giving the light marks any desired direction, d. h., the object of interest of the picture in question from different angles to be able to display, namely from above or below, right or left, without height parallax appear. If there are two original brands, these are expediently through a common drive rotated in the same direction.

Ein Ausführungsbeispiel unter Verwendung zweier Originalmarken ist in den Abbildungen dargestellt. In der in der Hand zu haltenden Zeigevorrichtung sind im Gehäuse i die Lichtquelle 2 und ein Kondensor 3, die Lichtmarken q., q.' und die Optik 6, 6' sowie Polarisationsfilter 7, 7' angeordnet. Die Originalmarken q., q.' können z. B. dadurch gleichsinnig verdreht werden, daß sie mit Zahnrädern versehen sind und über ein Zwischenrad 5 miteinander in Verbindung stehen. Dabei ragen die Zahnräder q, und q.' über das Gehäuse i heraus, so daß die beiden Marken durch Betätigung der Zahnräder direkt angetrieben werden können.An embodiment using two original brands is shown in the pictures. In the hand-held pointing device are in the housing i the light source 2 and a condenser 3, the light marks q., q. ' and the optics 6, 6 'and polarization filters 7, 7' are arranged. The original brands q., q. ' can e.g. B. be rotated in the same direction that they are with gears are provided and are connected to one another via an intermediate gear 5. Included the gears q and q protrude. ' over the housing i out so that the two marks can be driven directly by operating the gears.
