Description
Photographischer O#bjektivverschluß mit elektronischer Steuerung Zusatz zum Patent 1094 090 Die Erfindung betrifft einen photographischen Verschluß, dessen den Lichteinfall freigebende Teile mittels zweier aus Spannstellung ablaufender Antriebsglieder betätigt werden, wobei jedes der Antriebsglieder durch ein Haltemagnetsystem in der Spannstellung gehalten wird und elektronische - Mittel vorgesehen sind, welche nach Auslöung die Haltemagnetsysteme mit der zur Belichtung nötigen Zeitverzögerung steuern, entsprechend dem Patent 1094 090. Ihr Zweck ist die weitere Ausbildung der in dem Hauptpatent niedergelegten Erfindung. Diesem Zweck dient die Maßnahme, die zur Steuerung der Haltemagnetsysteme vorgesehenen elektronischen Mittel, welche zu in sich geschlossenen Baueinheiten zusammengefaßt sind, innerhalb des die mechanischen Teile des Verschlusses aufnehmenden Gehäuses unterzubringen.Photographic O # bjektivverschluß with electronic control additive patent 1094090 The invention relates to a photographic shutter, the light incidence releasing parts are operated by means of two expiring from the clamping position drive members, each of said drive members is held by a holding magnet system in the clamping position and electronic - means are provided which, after triggering, control the holding magnet systems with the time delay necessary for exposure, according to patent 1 094 090. Their purpose is the further development of the invention laid down in the main patent. This purpose is served by the measure of accommodating the electronic means provided for controlling the holding magnet systems, which are combined into self-contained structural units, within the housing that accommodates the mechanical parts of the lock.
Durch die erfindungsgemäße Maßnahme ist erreicht, daß die Montage eines gemäß dem Hauptpatent ausgebildeten Verschlusses wesentlich vereinfacht ist und daß die elektrischen Baueinheiten als fertige Zulieferteile bezogen werden können.By the measure according to the invention it is achieved that the assembly a closure designed according to the main patent is significantly simplified and that the electrical components can be obtained as finished parts from suppliers.
Schließlich ergibt sich ein besonders einfacher Zusammenbau einer mit einer Stromquelle ausgestatteten Kamera und dem erfindungsgemäßen Verschluß, wenn in weiterer Ausgestaltung der Zusatzerfindung zum Anschluß einer außerhalb des Verschlußgehäuses befindlichen Stromquelle an die innerhalb des Verschlußgehäuses befindlichen, die elektronische Steuerschaltung enthaltenden Baueinheiten ein Stecker am Verschlußgehäuse vorgesehen ist.Finally, there is a particularly simple assembly of a camera equipped with a power source and the shutter according to the invention, if in a further embodiment of the additional invention to connect an outside of the lock housing to the power source within the lock housing located, the electronic control circuit containing structural units a plug is provided on the lock housing.
Die aus der Beschreibung von Patent 1094 090 übemommenen Teile der Zeichnung zeigen in vereinfachter Darstellung in Fig. 1 einen photographischen Verschluß, zur Hälfte in Aufsicht, zur Hälfte axial geschnitten, Fig. 2 den Verschluß gemäß Fig. 1, von vorn ge-,sehen (Frontplatte und Belichtungszeitsteller sind entfernt).The übemommenen from the description of Patent 1,094,090 parts of the drawing showing in a simplified representation in Fig. 1, a photographic shutter, axially cut in half in plan view in half, Fig. 2 shows the closure according to FIG. 1, Ge from the front, see (front panel and exposure timer are removed).
In Fig. 1 ist, teilweise im Schnitt, der Stecker 82 mit den Polen 82 a und 82 b zu erkennen, über den die gesamte, im Verschlußgehäuse 10 befindliche elektrische Einrichtung an eine, vorzugsweise im Kameragehäuse untergebrachte Stromquelle angeschlossen ist. Schließlich ist durch die Ziffern 80 und 108 in Fig. 2 angedeutet, daß es zweckmäßig sein kann, die Elemente der beiden Verzögerungseinrichtungen, wie im Elektrogerätebau üblich, zu Baueinheiten zusammenzufassen.In Fig. 1 , partially in section, the plug 82 with the poles 82 a and 82 b can be seen, via which the entire electrical device located in the lock housing 10 is connected to a power source, preferably housed in the camera housing. Finally, the numbers 80 and 108 in FIG. 2 indicate that it can be expedient to combine the elements of the two delay devices into structural units, as is customary in electrical appliance construction.
