Description
Die Erfindung betrifft einen Bildwerfer zur Vorführung stehender Lichtbilder mittels Filmstreifen mit einem vor dem Objektiv in den Strahlengang eüischaltbaren und bei der Bildumstellung zum-Abfangen des Bildes sowie zur Kontrolle der Vorführungen dienenden Hilfsschirm nach Patent 618232.The invention relates to an image projector for Presentation of still photos using film strips with a in front of the lens the beam path eüischaltbaren and with the Image changeover to intercept the image as well as to control the demonstrations Auxiliary screen according to patent 618232.
Nach dem Hauptpatent ist der Hilfsschirm ■ derart angeordnet und über ein Gestänge mit einem in Richtung der optischen Achse verschiebbaren Objektivträger verbunden, daß das Objektiv zwangsläufig mit dem Ein- und Ausschalten des Hilfsschirmes verstellt wird und auf diesem zur Kontrolle "durch den Vorführenden ein Projektionsbüd in verkleinertem Maßstabe vor dem Projizieren auf den Hauptbildschirm erscheint.According to the main patent, the auxiliary screen is ■ so arranged and with a linkage one displaceable in the direction of the optical axis Lens carrier connected that the lens inevitably with the input and Switching off the auxiliary screen is adjusted and on this for control "by the demonstrator a reduced-scale projection booth before projecting onto the Main screen appears.
Die· vorliegende Erfindung dient demselben Zwecke wie die Einrichtung nach dem Hauptpatent, besitzt jedoch dieser gegenüber noch den Vorteil, daß. sie auch bei vorhandenen Bildwerfern nachträglich ohne Schwierigkel·- ,ten vorgesehen werden kann. Erfindungsgemäß sind auf einer . parallel zur optischen Achse in einer am Bildwerfer (z. B. Objektiv) befestigten Klammer drehbar sowie feststellbar gelagerten Stange der Hilfsschirm sowie eine Linse einstellbar angeordnete und in den Strahlengang des Bildwerfers durch 30' Drehen der Stange verschwenkbar.The present invention serves the same purpose Purposes such as the establishment according to the main patent, but this still has it the advantage that. they can also be retrofitted with existing projectors without difficulty - , th can be provided. According to the invention are on a. parallel to the optical Axis rotatable and lockable in a bracket attached to the projector (e.g. lens) mounted rod of the auxiliary screen and a lens adjustable and arranged can be pivoted into the beam path of the projector by turning the rod 30 '.
Auf der Zeichnung ist die Erfindung beispielsweise dargestellt.The invention is shown in the drawing, for example.
Mittels einer Klammer« wird die ganze Einrichtung an dem Bildwerfer, z. B. an dem Objektiv χ befestigt. In der Klammer α ist die mit einem Drehzapfen b versehene Stange d dreh- und festklenimbar gelagert, auf der eine Linsen sowie ein Hilfsbildschirm/ in Richtung der optischen Achse zwecks Erzielung eines scharfen Hilfsbildes verschieb- und feststellbar angeordnet sind. Durch Drehung der Stängel, wobei durch einen Stifte und einen festen Anschlag eine axiale Verschiebung der Stange d verhindert wird, wird die Linse e und der Hilfsschirm/ in den Projektionsstrahlengang gebracht.The entire device is attached to the projector, e.g. B. attached to the lens χ . In the bracket α , the rod d provided with a pivot b is rotatably and securely mounted, on which a lens and an auxiliary screen / are arranged so as to be displaceable and lockable in the direction of the optical axis in order to achieve a sharp auxiliary image. By rotating the stems, an axial displacement of the rod d being prevented by a pin and a fixed stop, the lens e and the auxiliary screen / are brought into the projection beam path.
