Description
Durchblicksucher für photographische Kameras Die Erfindung betrifft
einen Durchblicksucher an photographischen
Die bisher verwendeten Sucher aller Konstruktionen an photographischen Kameras weisen durch ihre Anordnung im oder am Kameragehäuse für Brillenträger oder für Kamerabenutzer,die nicht über normale Sehschärfe verfügen, den wesentlichen Nachteil auf, daß trotz Heranführung des Auges oder der Brille an den Suchereinblick das im Sucher wiedergegebene Bild unscharf, doppelkontuiig oder verschwommen wahrgenommen wird.The previously used viewfinders of all constructions on photographic Cameras have due to their arrangement in or on the camera housing for glasses wearers or for camera users who do not have normal visual acuity, the essential one Disadvantage that despite bringing the eye or the glasses to the viewfinder the image displayed in the viewfinder is perceived as blurred, double-contoured or blurred will.
Um Nachteile dieser Art, die in gleicher Weise bei Prismenfeldstechern und Monokularen aller Konstruktionen auftreten, zu beheben,gehört es zum Stand der Technik bei den genannten optischen Geräten Okulare zu verwenden, die entsprechend der Sehschärfe verstellbar sind und eine Dioptrieneichung aufweisen, um ein sofortiges Einstellen entsprechend der jeweiligen Sehschärfe zu ermöglichen.To disadvantages of this kind, the same with prism binoculars and monoculars of all constructions occur to fix, it belongs to the state of the art Technique for the mentioned optical devices to use eyepieces accordingly visual acuity are adjustable and have a diopter calibration for an instant To allow adjustment according to the respective visual acuity.
Die Erfindung soll den oben aufgezeigten Mangel an Suchern für photographische Kameras beseitigen und schafft einen suchereinblick, der in gleicher Weise für Kamerabenutzer mit norm maler oder verminderter Schschärfe verwendbar ist. Zu diesem Zweck ist der Suchereinblich an Kameras in Form eines an sich bekannten, nach Dioptrien verstellbaren Okulars ausgebildet, das mit einer Dioptrieneichung oder-skala versehen ist.The invention is intended to address the above identified deficiency in viewfinders for photographic use Eliminate cameras and creates a viewfinder insight that is equally common to camera users Can be used with standard painter or reduced sharpness. To that end is the viewfinder on cameras in the form of a known per se, adjustable according to dioptres Formed eyepiece, which is provided with a diopter calibration or scale.
Das fest am Kameragehäuse angeordnete, als Suchereinblick ausgebildete Okular kann mittels eines Schneckenganges verstellbar ausgebildet sein, jedoch schliesst das Wesen der Erfindung andere Lösungen, wie beispielsweise die Verstellbarkeit mittels eines in einem schraubenlinienförmigen Schlitz geführten Stiftes oder eines federbelasteten Stecktubus, der in einer Hülse verschieblich geführt ist, nicht aus. Auch in der zuletzt aufgeführten Ausführungsform ist eine Dioptrieneichung am Tubus vorgesehen, und zwar an dessen Aussenwandung.The fixed to the camera housing, designed as a viewfinder The eyepiece can be designed to be adjustable by means of a worm gear, but it closes the essence of the invention other solutions, such as adjustability by means of a pin guided in a helical slot or a spring-loaded plug-in tube, which is guided displaceably in a sleeve, not the end. A diopter calibration is also used in the last-mentioned embodiment provided on the tube, namely on its outer wall.
Der als Okular ausgebildete Suchereinblick ist nach der Erfindung so dimensioniert, dass sein äusserer Rand das Kameragehäuse oder den Priamenaufsatz nicht überragt.The viewfinder eyepiece designed as an eyepiece is according to the invention dimensioned so that its outer edge the camera housing or the preamble attachment not towered over.
Eine Verwendungsmöglichkeit für das erfindungsgemässe Suchereinblickokular ist auch in Verbindung mit Fernrohr- (Newton-)-Suchern, Brilliant- oder Spiegelsuchern durchaus gegeben.A possible use for the viewfinder eyepiece according to the invention is also in connection with telescope (Newton) finders, brilliant or mirror finders absolutely given.
Ein weiterer Vorteil des verstellbaren Suchereinblickokulars besteht ferner darin, dann auch die im Sucher sichtbaren Nachführzeiger für eingebaute Belichtungsmesser, Blenden-und Verschlusszeitenangaben sowie e-Messwerte, die eingespiegelten Sueherausschnitte für verschiedene Wechseloptiken etc. durch die Verstellbarkeit zusammen oder unabhängig vom Sucherbild eingestellt und abgelesen werden können.Another advantage of the adjustable viewfinder eyepiece is also in it, then also the tracking pointer for built-in exposure meters, visible in the viewfinder, Aperture and shutter speed information as well as e-measured values, the mirrored viewer details for different interchangeable optics etc. due to the adjustability together or independently can be set and read from the viewfinder image.
Die Zeichnung stellt den Erfindungsgegenstand dar. Es zeigen : Fig. 1 das als Suchereinblick ausgebildete Okular, beispielsweise in Verbindung mit einem Pentaprismensueher, hierbei Verstellbarkeit durch Schneckengang, Fig. 2 die Verytellbarkeit des Okulars mittels eines in einem Xchraubenschlitz geführten Stiftes.The drawing represents the subject matter of the invention. It shows: Fig. 1 designed as a viewfinder eyepiece, for example in connection with a Pentaprism sensor, here adjustability by worm gear, Fig. 2 the adjustability of the eyepiece by means of a pin guided in a screw slot.
In der Kameragehäusewand 1 ist die Okularfassung 2 mit der Linso 3 mittels eines Schneckenganges 4 drehverstellbar gehaltert, und zwar vor dem Pentaprisma 5. In der zweiten Ausführungsform entsprechend Figur 2 ist die Okularfassung 2 mit anschliessendem Tubus 6 in der Hülse 9 geführt, derart, dass hier beispielsweise die Hülse 9 einen schraubenlinienförmigen Schlitz 7 aufweist, in welchem der Tubus 6 mittels des an ihm befestigten Stiftes 8 drehverstellbar geführt ist.The eyepiece mount 2 with the Linso 3 is in the camera housing wall 1 supported rotatably by means of a worm gear 4, in front of the pentaprism 5. In the second embodiment according to FIG. 2, the eyepiece mount 2 is with subsequent tube 6 guided in the sleeve 9, such that here, for example the sleeve 9 has a helical slot 7 in which the tube 6 is guided rotatably adjustable by means of the pin 8 attached to it.
