Description
Die Erfindung betrifft eine Vorrichtung zur Projektion undurchsichtiger Gegenstände) Abbildungen u. dgl. Bisher sind derartige Vorrichtungen bekannt geworden zur Projektion nach einer Seite. Nach der Erfindung soll das Projizieren eines undurchsichtigen Gegenstandes gleichzeitig von und nach zwei Seiten erreicht werden, und zwar dadurch, daß die Lichtstrahlen der Lichtquelle aufThe invention relates to a device for projecting opaque objects) Images and the like. So far, such devices have become known for projection to one side. According to the invention, the projecting of an opaque Object can be reached simultaneously from and to two sides, namely by that the light rays of the light source on
ίο Spiegelpaare treffen, die zur linken und zur rechten Seite der Lichtquelle angeordnet sind und die Strahlen auf zwei gegenüberliegende Seiten des undurchsichtigen Gegenstandes werfen. Jeder dieser Seiten des zu projizierenden Gegenstandes ist ein Objektiv zugeordnet. Die Erfindung ist in der Zeichnung in einer Ausführungsform beispielsweise schematisch veranschaulicht.ίο meet pairs of mirrors to the left and to the right side of the light source are arranged and the rays on two opposite Throw sides of the opaque object. Each of these sides of the projected A lens is assigned to the object. The invention is shown in the drawing in one embodiment, for example illustrated schematically.
Die Lichtquellen hat zu beiden Seiten dieThe light sources has the on both sides
ao Spiegelt,δ' und c, c' und die Objektivere', d, d! ist ein undurchsichtiges mit Bildern oder Schriftstreifen beiderseitig versehenes Film- oder Projektionsband. Dieses Band kann auch aus einzelnen Bildern bestehen, welche durch Scharniere miteinander verbunden sind.ao mirrors, δ 'and c, c' and the more objective ', d, d! is an opaque film or projection tape with pictures or stripes on both sides. This band can also consist of individual images, which are connected to one another by hinges.
Von der elektrischen Lampe« fallen die Lichtstrahlen seitlich auf die Spiegel δ und δ' und gleichzeitig auf die Spiegele und c', welche so eingestellt sind, daß die Strahlen von den Spiegeln b und c auf die Seite d und die Strahlen von den Spiegeln 6'undc' •auf die Seited! des undurchsichtigen Bildes geworfen werden. Von hier gelangen die Lichtstrahlen durch die Objektivem und e' auf die Projektionsfläche.The light rays from the electric lamp “fall laterally on the mirrors δ and δ 'and at the same time on the mirrors and c', which are adjusted so that the rays from the mirrors b and c on the side d and the rays from the mirrors 6 'undc' • on side d! of the opaque image. From here the light rays pass through the objectives and e ' onto the projection surface.
Die Bilder können auch so eingerichtet sein, daß jedes einzelne Bild leicht entfernt und durch ein anderes ersetzt werden kann.The images can also be arranged so that each individual image is easily removed and can be replaced by another.
Anstatt einer Lampe können auch zwei Lampen in Anwendung kommen. Das Filmband oder der Projektionsstreifen kann auch aus wärmebeständigem Material angefertigt werden.Instead of one lamp, two lamps can also be used. The film tape or the projection strip can also made of heat-resistant material.
