Description

Bildwerfer zur Vorführung von plattenförmigen Einzelbildern mit einer Drehscheibe Die Erfindung geht aus von einem Bildwerfer zur Vorführung von plattenförmigen Einzelbildern mit einer die Bilder fördernden Drehscheibe.Projector for the presentation of plate-shaped individual images with a Turntable The invention is based on a projector for demonstrating plate-shaped Individual images with a turntable promoting the images.

Bei einem bekannten Bildwerfer dieser Art waren die Bilder in die Drehscheibe einzusetzen und wurden unter absatzweiser Drehung dieser Scheibe nacheinander durch den Bildwurfstrahlengang hindurchgetfiihrt. Deingegenüber kommt gemäß der Erfindung als Drehscheibe lediglich eitle Scheibe mit einem den Strahlengang zur Projektion jeweils freigebenden, sektorförmi`en Blendenausschnitt und einem das jeweils iin Bildfenster stehende Bild nach der Projektion beiseite schiebenden Mitnehmerstift zur Anwendung. Die Drehscheibe ist also nicht unmittelbarer Bilderträger, sondern Bewirkt den Bildwechsel unter Abdeckung des Bildwurfstrahlenganges nur mittelbar als Schieber, wie dies an sich unter Anwendung von geradlinig hin und her zu hwegenden Schiebern bekannt ist. Gegen-Über solchen Bilüwecliseleinriclitutigen zeichnet sich die erfiiidung<gemäße durch F-,infachieit aus. Sie bietet ferner auch dabei ohne weitere Schwierigkeiten die Möglichkeit zu motorischem Antrieb der Bildwechseleinrichtung. Ein weiterer Vorteil besteht darin, daß das Einlegen und das Herausnehmen ,der Dias sowie die Betätigung der Scheibe von einer Seite des Bildwerfers aus vorgenommen wer--Ien können.With a known projector of this type, the images were in the Insert turntable and were successively rotating this disc one at a time guided through the image beam path. On the other hand, according to the Invention as a turntable only vain disc with a beam path to Projection, in each case releasing, sector-shaped aperture cutout and a das Pushing the driver pin aside after the projection in each picture standing in the picture window to use. The turntable is not the direct carrier of images, but rather Only causes the image change indirectly while covering the image beam path as a slide, like this in and of itself, using straight lines to move back and forth Is known to slide. Opposite such Bilüwecliseleinriclitutigen stands out the fulfillment is defined by F-, simplicity. It also offers without further difficulties the possibility of motorized drive of the picture changing device. Another advantage is that the insertion and removal of slides as well as the actuation of the disc made from one side of the projector who - Ien can.

Ein Ausführungsbeispiel des Erfindungsgegenstandes ist auf der Zeichnung dargestellt, und zwar zeigt Abb. i die Bildwechseleinrichtung im Schnitt, Abb.2 in Ansicht und Abb.3 die Anordnung des Mitnehmerstiftes in größerem Maßstab.An embodiment of the subject matter of the invention is shown in the drawing shown, namely Fig. i shows the image changing device in section, Fig.2 in view and Fig. 3 the arrangement of the driving pin on a larger scale.

Am Ende eines an sich bekannten Fallschachten i ist die umlaufende Scheibe 2 mit eitlem sektorförmigen Ausschnitt vorgesehen. Die Scheibe ist raumsparend über dem Bildfenster 3 angeordnet und trägt einen Kurbellrrift d, der den in seiner Längsachse federnden Stift 5 enthält. Dreht man am Griff q. die Scheibe in Pfeilrichtung um die Achse 6, so geht die Kante 7 des Ausschnitts der Blenden-;Cheibe durch den Abbildungsstrahlengang und deckt diesen ab. Die vollständige Verdunklung ist erreicht, wenn der Griff q. an der Stelle 8 angekommen ist. Bei 8 ist die Führungsschiene y des Fallschachtes mit einer in Richtung auf das Dia abfallenden ,;cliiefen Ebene versehen, auf der der Stift 5 in die Ebene des Dias gleitet und dieses beim Weiterdrehen aus dem Bildfenster schiebt.At the end of a known chute i is the circumferential one Disc 2 provided with a vain sector-shaped cutout. The disc is space-saving Arranged over the image window 3 and carries a crank drift d, which is in his Contains longitudinal axis resilient pin 5. If you turn the handle q. the disc in the direction of the arrow around the axis 6, the edge 7 of the cutout of the diaphragm; Cheibe goes through the Imaging beam path and covers it. The complete blackout is achieved, when the handle q. has arrived at point 8. At 8 is the guide rail y of the chute with a sloping plane in the direction of the slide provided, on which the pin 5 slides into the plane of the slide and this when turning further out of the image window.

Ist das Dia aus dem Fallschacht herausgeschoben, fällt das folgende von dem im Fallschacht steckenden Dias in -den Abbi Idungsstrahlengang. Beim Weiterdrehen gleitet der Stift 5 auf einer zweiten schiefen Ebene bei io wieder aus der Ebene des Fallnchachtes auf die Höhe dessen Deckplatte und wird hier über den Fallschacht geführt. Nach vollzogenem Bildwechsel geht die Kante i i der Blende durch den Abbildungsstrahlengang und gibt ihn wiederfrei.If the slide is pushed out of the chute, the next one falls of the slide stuck in the chute in the illustration beam path. As you continue to turn the pin 5 slides out of the plane again on a second inclined plane at io of the chute to the level of its cover plate and is here over the chute guided. After the image change has been completed, the edge i i of the diaphragm goes through the imaging beam path and releases it again.
