Description

Einrichtung zum gleichzeitigen Kopieren der Farbauszüge eines Linsenrasterfilms Das Hauptpatent betrifft eine Einrichtung zum gleichzeitigen Kopieren der Farbauszüge eines dreistreifigen Linsenrasterfilms mit mehreren voneinander unabhängig in ihrer Intensität regelbaren Lichtquellen. Gemäß dem Hauptpatent sind bei einer solchen Einrichtung zwei hintereinanderliegende Lichtquellen vorgesehen, welche in der Weise drei in ihrem Querschnitt je einer Farbstreifenzone entsprechende Beleuchtungsröhren speisen, d.aß das Licht der einen Lichtquelle. über spiegelnde Flächen in zwei Lichtströme gleicher Intensität aufgespalten in die beiden äußeren Beleuchtungsröhren gelangt, während das Licht der von der ersten Lichtquelle abgeschirmten zweiten Lichtquelle ungeteilt in die mittlere Beleuchtungsröhre eintritt.Device for simultaneous copying of the color separations of a lenticular film The main patent relates to a device for simultaneous copying of the color separations a three-striped lenticular lens film with several independent of each other in their Adjustable light sources. According to the main patent, such Device two light sources one behind the other provided, which in the way three lighting tubes each corresponding in their cross-section to a colored strip zone dine, that is, the light of one source of light. Via reflective surfaces into two luminous fluxes split into the two outer lighting tubes with the same intensity, while the light of the second light source shielded by the first light source Enters undivided into the central lighting tube.

Gegenstand der Erfindung ist eine Weiterbildung dieser Kopiereinrichtung zum Kopieren des Frontfilms von Linsenrasterbipackfilmen. Zum Kopieren des z. B. den Blau-und Grünauszug enthaltenden Linsenrasterfrontfihns wird bekanntlich ein symmetrisches Streifenfilter verwendet, dessen beide äußere Farbstreifen gleiche Farbe haben. Da also die beiden äußeren Filterstreifen dem gleichen Farbauszug zugeordnet sind, ist erfindungsgemäß das zur Ausleuchtung dieser beiden äußeren Streifen des Kopierfilters dienende Licht vor der Strahlenteilung durch eine einzige Blende in seiner Intensität regelbar. Dadurch wird die Gewähr gegeben, daß die Ausleuchtung dieser Streifen stets gleichmäßig .erfolgt. Die Zeichnung gibt ein Ausführungsbeispiel des Erfindungsgegenstandes wieder.The subject of the invention is a further development of this copier for copying the front film of lenticular bi-pack films. To copy the z. B. As is known, a lenticular lens front film containing the blue and green separation is used symmetrical strip filter is used, the two outer color strips of which are the same Have color. Since the two outer filter strips are assigned to the same color separation are, according to the invention, is to illuminate these two outer strips of the Copying filter serving light in front of the beam splitting by a single diaphragm its intensity adjustable. This ensures that the illumination this stripe always takes place evenly. The drawing gives an embodiment of the subject matter of the invention again.

Das Licht der zum Kopieren des Blauauszuges dienenden Lichtquelle 16 wird von dem optischen System 13 durch die Lichtröhre 2o auf die Mattscheibe 21 geworfen und beleuchtet den mittleren Filterstreifen 22. Die Regelung der Lichtstärke erfolgt durch die Blende 18. Das Licht der zum Kopieren des Grünauszuges dienenden Lichtquelle i wird durch das optische System 8 auf die Spiegel 2 und 3 oder einen entsprechenden Strahlenteiler geworfen und gelangt von dort auf die Spiegel 4. und 5, die die Lichtstrahlen durch die Lichtröhren i o und i i auf die Mattscheiben 12 und 13 werfen und die grünfarbigen Filterstreifen 14 und 15 ausleuchten. D:e Intensität der Ausleuchtung dieser beiden Filterstreifen wird nun gemeinsam durch die Blende 6, die sich hinter dem optischen System 8 befindet, vor der Strahlenteilung geregelt, so daß auf die Streifen 14 und 15 in jedem Falle die gleiche Lichtmenge auftrifft.The light from the light source used to copy the blue extract 16 is from the optical system 13 through the light tube 2o onto the ground glass 21 thrown and illuminates the middle filter strip 22. The regulation of the light intensity takes place through the aperture 18. The light of the used for copying the green extract Light source i is through the optical system 8 on the mirrors 2 and 3 or one corresponding beam splitter and from there it reaches the mirrors 4. and 5, the rays of light through the light tubes i o and i i onto the focusing screens Throw 12 and 13 and illuminate the green colored filter strips 14 and 15. D: e The intensity of the illumination of these two filter strips is now through jointly the diaphragm 6, which is located behind the optical system 8, in front of the beam splitting regulated so that on the strips 14 and 15 in each case the same amount of light hits.
