Description
Betrachtungsgerät für Diapositive Gegenstand vorliegender Erfindung ist ein Be trachtungsgerät für Diapositive, umfassend einen Projektor und eine Transparentplatte. Derartige Geräte werden neuerdings vielfach als Reklamege räte oder Blickfang in Schaufenstern von Verkaufs geschäften verwendet, wo aber vielfach der zur Er zielung einer genügenden Bildvergrösserung notwen dige Raum zwischen dem Projektor und der Trans parentplatte nicht verfügbar ist, so dass der Projektor irgendwo im Geschäftsraum und die davon getrennte Transparentplatte im Schaufenster plaziert werden muss.
Die Erfindung setzt sich die Schaffung eines eine bauliche Einheit von verhältnismässig geringen Dimensionen darstellenden Gerätes, das tagsüber im Schaufenster stehen kann oder als Ganzes leicht transportierbar ist.
Erfindungsgemäss ist darum vorgesehen, dass der Strahlengang zwischen der Austrittslinse des Pro- jektors und der Transparentplatte durch Planreflek toren mehrfach gefaltet ist.
Ein Ausführungsbeispiel eines solchen Gerätes ist in der Zeichnung im Aufriss dargestellt.
In einem Gehäuse 1 ist auf einer Bodenplatte 11 ein Projektor 2 handelsüblicher Bauart nach vor- und rückwärts und seitwärts justierbar, beispiels weise mittels Langlöcher oder Schlitze der Boden- platte 1 durchsetzenden Schrauben 20 befestigt.
An einem Frontende des Projektorsockels gelenkig und feststellbar montierten Träger ist ebenfalls gelenkig und feststellbar ein Planspiegel 31 befestigt. Über diesem ist an einer Seitenwand des Gehäuses 1 ein zweiter grösserer Planspiegel 32 in 90 -Orientierung zum ersten befestigt, der die empfangene Strahlung zu der in der Gehäusefrontwand 10 eingesetzten Transparentplatte bzw. Mattscheibe 4 umlenkt, die als Bildschirm des Betrachtungsgerätes dient.
Viewing device for slides The present invention is a viewing device for slides, comprising a projector and a transparent plate. Such devices are recently often used as advertising devices or eye-catchers in shop windows, but where often the necessary space between the projector and the trans parent plate to achieve sufficient image enlargement is not available, so that the projector somewhere in the shop and the a separate transparent plate must be placed in the shop window.
The invention aims to create a device which represents a structural unit of relatively small dimensions and which can be placed in the shop window during the day or which can be easily transported as a whole.
According to the invention, it is therefore provided that the beam path between the exit lens of the projector and the transparent plate is folded several times by plane reflectors.
An embodiment of such a device is shown in the drawing in elevation.
In a housing 1, a projector 2 of commercially available design is adjustable forwards, backwards and sideways on a base plate 11, for example fastened by means of screws 20 penetrating the base plate 1 by means of elongated holes or slots.
At a front end of the projector base articulated and lockable mounted carrier is also articulated and lockable a plane mirror 31 is attached. Above this, on a side wall of the housing 1, a second larger plane mirror 32 is attached in 90 -orientation to the first, which deflects the received radiation to the transparent plate or ground glass 4 inserted in the housing front wall 10, which serves as the screen of the viewing device.
