Description

Bildwerfer und -betrachter, bei denen die Bildplatten o. dgl. in einem unter Federdruck stehenden Stapel oberhalb des Bildfensters oder der Betrachtungsstelle so angeordnet sind, daß jeweils nur die erste unmittelbar über dem Bildfenster ο. dgl. befindliche Platte nach unten in dieses gelangen kann, sind bekannt. Der Bildwechsel erfolgt bei diesem Bekannten durch eine Vorrichtung, die die jeweils erste Platte des Stapels von diesem weg vor das Bildfenster zieht. Unter der Wirkung des Stapeldruckes verschrammen hierbei aber die Platten o. dgl. leicht. Dies und eine besondere Abziehvorrichtung überhaupt wird gemäß der vorliegenden Erfindung in einfacher Weise dadurch vermieden, daß ζ. Β. durch einen Hebelschalter der Spanndruck des Bilderstapels sich so weit aufheben läßt, daß die erste unmittelbar über dem. Bildfenster befindliche Platte o. dgl. des Stapels selbsttätig in die Projektions- bzw. Betrachtungsstellung gleitet. Image projector and viewer, in which the image plates o. The like. In one under spring pressure standing stack above the image window or the viewing point so arranged are that only the first one immediately above the image window ο. Like. Located plate can get down into this are known. The picture change takes place with this Known by a device that moves the first plate of the stack away from it in front of the image window. Scratched under the effect of the stack pressure but the plates or the like easily. This and a special pulling device in general is avoided according to the present invention in a simple manner that ζ. Β. the clamping pressure of the stack of images can be released by means of a lever switch, that the first immediately above the. Image window located plate or the like of the stack automatically slides into the projection or viewing position.

In der Zeichnung ist schematisch der neue Apparat dargestellt.In the drawing, the new apparatus is shown schematically.

Der Kolben b, der durch die Feder c ständig in Richtung der vorderen Stirnwand d eines Lagerraumes e gezogen wird, spannt zwischen sich und dieser Stirnwand den Plattenstapel ein. Wird der Kolben b durch Betätigen des Hebels α entgegen der Wirkung der Federe zurückgezogen, so gleitet die jeweils vorderste Platte, da der Einspanndruck aufgehoben ist, unter der Wirkung ihres Gewichtes ab und wird von dem bekannten, nach Art eines Uhrenankers arbeitenden Sperrhebel h bzw. den darauf schon ruhenden Platten abgefangen. Der Sperrhebel h wird durch einen besonderen Handhebel j betätigt, er kann aber auch mit dem Hebel ο des Einspannkolbens b gekuppelt sein, so daß beim Plattenwechsel gleichzeitig der Ankersperrhebel h umgelegt wird, der auch die Freigabe der projizierten bzw. unmittelbar betrachteten Bilder zur Ablegestelle I regelt.The piston b, which is constantly pulled by the spring c in the direction of the front end wall d of a storage space e , clamps the plate stack between itself and this end wall. If the piston b is pulled back against the action of the spring by actuating the lever α , the foremost plate in each case slides under the action of its weight, since the clamping pressure has been released, and is locked by the known locking lever h resp. intercepted the plates already resting on it. The lock lever h j is actuated by a special hand lever, but it can also be connected to the lever ο be coupled b of Einspannkolbens, so that at the same time the armature blocking lever is folded h during plate changing, the I and the release of the projected or directly viewed images to the pier regulates.

Zur Beleuchtung der Bilder sind eine oder mehrere Lichtquellen i vorgesehen. Die Projektionsoptik läßt sich durch einen Stereobetrachter ersetzen. Durch Einschieben farbiger Platten in den Beleuchtungsstrahlengang läßt sich ein mehrfarbiges oder buntfarbiges 5a Bild erzielen.One or more light sources i are provided to illuminate the images. The projection optics can be replaced by a stereo viewer. By inserting colored plates into the illumination beam path, a multicolored or multicolored 5a image can be achieved.

Außerdem können die Diapositive mit einem Deckglas versehen sein.In addition, the slides can be provided with a cover glass.
