Description
Die Erfindung betrifft eine Abänderung der in dem Patent 332946 beschriebenen Vorrichtung, und zwar soll sich die Änderung auf die Beleuchtung beziehen. Mit dem Zählwerk sind zwei eng nebeneinanderliegende Lampen bzw. eine Doppellampe verbunden, derart, daß nur diejenige Lampe oder diejenige Hälfte der Doppellampe leuchtet, vor der jedesmal das richtig durch das FiImfenster laufende Filmband sich gerade befindet, während die andere Lampe bzw. die andere Hälfte der Doppellampe erloschen ist. Die Zeichnung zeigt das Schaltungsschema hierzu. Von den Hauptleitungen 44 und 45 sind die zum Motor 4 führenden Leitungen 46 und 47 abgezweigt und von diesen wiederum die zur Lichtquelle 31 unter Einschaltung eines Widerstandes 48 führenden Leitungen 49, 50 und 59. Von den Leitungen 46 und 47 sind Leitungen 52 und 53 abgezweigt, die mit Hilfe eines Widerstandes 54 einen Schwachstromkreis bilden, der durch die beiden Zählwerke 36 hindurchgeführt ist, und zu den beiden Relais 55 und 56 für die Umsteuerung des Motors und zu den Relais 57 und 58 für die Schaltung der Lampe 31 geht, die zwei getrennte Glühkörper besitzt. An Stelle dieser Doppellampe können natürlich auch zwei Lampen benutzt werden.The invention relates to a modification of the device described in patent 332946, namely, the change should relate to the lighting. With the Counter are two lamps located close to each other or one double lamp connected, in such a way that only that lamp or that half of the double lamp lights up in front of which the correct one always shines through the window tape is currently running while the other lamp or the other half of the double lamp has gone out. The drawing shows the circuit diagram for this. From main lines 44 and 45 the lines 46 and 47 leading to the motor 4 are branched off and from these in turn those to the light source 31 are switched on lines 49, 50 and 59 carrying a resistor 48. Lines 52 and 53 are branched off from lines 46 and 47, which, with the aid of a resistor 54, form a weak current circuit that passes through the two counters 36 is, and to the two relays 55 and 56 for reversing the motor and goes to the relays 57 and 58 for switching the lamp 31, the two separate incandescent bodies owns. Instead of this double lamp, two lamps can of course also be used.
Bei der dargestellten Stellung der Teile ist angenommen, daß das Relais 55 seinen Anker so beeinflußt, daß der Motor 4 nach der einen Drehrichtung angetrieben wird und dadurch auch die Filmbänder in Bewegung gesetzt werden. Kurz vor dem Ablauf des Films gelangt das eine Zählwerk auf die eingestellte Zahl und schließt dadurch den Stromkreis des Relais 56, während das andere Zählwerk den Stromkreis des Relais 55 unterbricht. Infolgedessen wird der Motor durch Umstellen der von dem Relais beeinflußten Schalter umgesteuert und treibt nun die Filmbänder in umgekehrter Richtung an.In the illustrated position of the parts, it is assumed that the relay 55 is its armature influenced so that the motor 4 is driven in one direction of rotation and thereby the film tapes are also set in motion. Shortly before the end of the film, one counter reaches the set one Number and thereby closes the circuit of the relay 56, while the other counter the circuit of the relay 55 interrupts. As a result, the motor is influenced by switching the relay Switch is reversed and now drives the film tapes in the opposite direction.
In gleicher Weise werden durch die Zählwerke die beiden Relais 57 und 58 beeinflußt, so daß gleichzeitig mit der Umsteuerung des Filmantriebes auch die Lampen bzw. die Doppellampe, entsprechend abwechselnd leuchten oder erlöschen. Nach erneutem Ablaufe der Filmbänder wiederholt sich der Umsteuerungsvorgang im umgekehrten Sinne.The two relays 57 and 58 are influenced in the same way by the counters, so that simultaneously with the reversal of the film drive and the lamps or the Double lamp, light up or go out alternately. After another expiration of the film tapes, the reversing process is repeated in the opposite direction.
