ι. Einrichtung zur fotografischen Vervielfältigung mittels Belichtung durch Blitzlicht, das durch Umsetzung gespeicherter elektrischer Energie in einer Gasentladungsstrcckc erzeugt wird, dadurch gekennzeichnet, daß mindestens zwei Gasentladungslampen (3) seitlich der Kamera (2) vorgesehen sind, von denen jede an mindestens zwei Speicherkondensatoren in zyklischer Vertauschung anzuschalten ist.ι. Photographic reproduction facility by means of exposure to flash light, which is generated by converting stored electrical Energy is generated in a gas discharge line, characterized in that at least two gas discharge lamps (3) are provided to the side of the camera (2), each of which is on at least two storage capacitors must be switched on cyclically.

2. Einrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Kamera (2) mit dcnElektronenblitzlampen und Reflektoren (3) auf oder über einem Arbeitstisch (1) nach oben gerichtet angeordnet ist, während unter dem Tisch die Energieversorgungsaggregate mit Spannungserzeugung, Speicherkondcusatoreu, Verteiler- und Zündschaltung untergebracht sind, und dadurch, daß in an sich bekannter Weise Kamera und Reflektoren auf eine Ebene vorzugsweise fest eingestellt sind, in der eine Glasplatte (5) angeordnet ist, auf der die Vorlagen (6) mit ihrer Fläche nach unten aufgelegt und gegen eine Kante (7) angelegt werden.2. Device according to claim 1, characterized in that that the camera (2) with electronic flash lamps and reflectors (3) on or above a work table (1) is arranged facing upwards, while under the table the Power supply units with voltage generation, storage capacitors, distribution and ignition circuit are housed, and in that in a known manner camera and reflectors are preferably permanently set on a plane in which a glass plate (5) is arranged on which the templates (6) are placed with their surface facing down and against an edge (7) can be created.

3. Einrichtung nach Anspruch 2, dadurch gekennzeichnet, daß vor die öffnungen der Reflektoren (3) abgestufte Filter zur gleichmäßigen Ausleuchtung der Vorlage (6) gesetzt werden können.3. Device according to claim 2, characterized in that in front of the openings of the reflectors (3) Graduated filters can be used to evenly illuminate the template (6) be able.

l) ie Crimean (IiIHg relates to an execution of photographic copying by means of exposure by flash that stored by conversion of electric energy is generated in a Gasentladungsstivekc, for example, with a photographic recording device for micro-Reproduktioneii. Known is the receiving box with several 1 lochleistungs- Constantly illuminating metal wire lamps, which are expensive to purchase and use electrical energy and have a short lifespan.

According to the invention, there are at least two or more gas discharge lamps on the side of the camera provided, each of which is connected to at least two storage capacitors in cyclical exchange is to be switched on. The discharge lamps can consist of one or, advantageously, of each a Kuergieversorgungsgerät, the power source, means for high voltage generation, storage capacitor and ignition device, the ignition being supplied by a main unit can be done via a line or photoelectrically. By the measure of the invention that the necessary electrical Knergie is made available in at least two storage capacitors, which alternate connected to the discharge lamp supplied by them, it is possible to control the discharge lamp supplied by them shorten the waiting time between two recordings without overdimensioning the energy supply device must and becomes heavy and expensive as a result.

An arrangement known per se in which the micro-recording device with the cellophane flash lamp or lamps and their reflectors on or above a work table is arranged cleared above. l) i <· camera and reflectors are preferably on one level fixed, in which a glass plate is arranged on which the reproductions in a Face down and placed against an edge. Books need as special The advantage of this arrangement is to be opened only at a right angle, so that the soites are effortless lie flat without overstretching the spine.

In the drawing, this last arrangement is shown in a schematic representation as an example.

With ι the table is referred to on which the camera 2 and the reflectors 3 of the gas discharge lamps are arranged facing upwards. On a template holder 4, at a distance L, which can also be adjustable, is a glass plate 5, on which, in the example of the illustration, a book 6 for reproducing a page is placed. The edge 7 forms the stop; the unused half of the book hangs down on the side of the frame. Graduated filters can be placed in front of the openings of the reflectors 3 in order to illuminate the template more evenly.
