Description
Gebrauchsmusteranmeldung "Bildführung für Diapositive an Projektions-oder
Betrachtungsgeräten"
Es ist bekannt, Projektionsgeräte mit Fenster oder Klappen zu versehen, die einen Teil des Lichtes austreten lassen, um die Grundplatte, auf der das Gerät steht, zu beleuchten, damit der Vorführende die Möglichkeit hat, sich vor dem Einführen des Diapositivs in den Bildschieber bzw. Bildführung über das Motiv zu informieren oder den dazu passenden Text zu lesen. Trotzdem kommt es immer wieder vor, daß kopfstehend oder seitenverkehrt eingelegte Bilder in den Projektionsstrahlengang gelangen. Diesen Übelstand zu beseitigen ist der Zweck vorliegender Neuerung. It is known to provide projection devices with windows or flaps, which let some of the light escape to the base plate on which the device to illuminate so that the demonstrator has the opportunity to introduce himself of the slide in the slide or image guide to inform about the motif or to read the appropriate text. Nevertheless it happens again and again that standing upside down or reversed inserted images get into the projection beam path. This one The purpose of the present innovation is to eliminate the problem.
Nach der Neuerung ist zur Bildführung eines Projektion-oder Betrachtungsgerätes, und zwar im bzw. zum Fallschacht, Bildschieber oder dergleichen im Bereich des nachfolgend zu projizierende Bildes ein Beobachtungsfenster angeordnet, in welchem das Diapositiv vor seiner Projektion zur Betrachtung des Motivs und zur Kontrolle seiner Einlegestellung sichtbar gemacht wird. Durch Vorschalten eines oder mehrerer Spiegel vor das Betrachtungsfenster läßt sich die Beobachtungstelle für den Vorführenden beliebig verlegen. According to the innovation, for image guidance of a projection or viewing device, namely in or to the chute, picture slide or the like in the area of the following To be projected image arranged an observation window in which the slide before its projection to view the motif and to check its placement is made visible. By placing one or more mirrors in front of the viewing window can be the observation point for the Relocate the presenter as desired.
Gleichzeitig kann die vom Beobachtungsfenster ausgehende Wärmestrahlung dazu ausgenutzt werden, die Diapositive vorzuwärmen, um eventuell Feuchtigkeitsrückstände zu beseitigen. At the same time, the heat radiation emanating from the observation window can be used to preheat the slides to remove any moisture residues to eliminate.
Ein Ausführungsbeispiel der Neuerung zeigt eine Bildführung mit Beobachtungsfenster an einem Projektionsgerät. Es zeigen : Abb. 1 eine Ansicht der Bildführung Abb. 2 einen teilweisen Schnitt durch die Seitenansicht der Bildführung des Projektorgehäuses und des Unterteils des Projektorgehäuses. One embodiment of the innovation shows an image guide with an observation window on a projection device. They show: Fig. 1 a view of the image guide Fig. 2 shows a partial section through the side view of the image guide of the projector housing and the bottom of the projector housing.
Die am Projektorgehäuse 1 befestigte Bildführung besteht aus demhLnteren,
lampenseitigen Teil 2 und dem Vorderteil 3, die mittels der Schrauben 4 miteinander
verbunden sind.
