Description
Gebrauchsmusteranmeldung "SuchergalileischerBauartfürphotographische und xinematographische Cameras Die Neuerung betrifft einen Sucher galileischer Bauart nach Patent 746 974, bei dem ein Bildbegrenzungsrahmen durch zwei zwischen den Suaherlinsen befindliche Planspiegel in die Schärfenebene des Sucherokulars gespiegelt wird.Utility model registration "SuchergalilischerBauartfürphotographic and xinematographic cameras. The innovation concerns a Galilean type viewfinder according to patent 746,974, in which an image bounding frame by two between the Suaher lenses located plane mirror is reflected in the focal plane of the viewfinder eyepiece.
Damit die Vorteile. die ein Sucher der vorerwähnten Bauart besitzt,
auch für Meßsucher nutzbar werden, müssen die optischen Seile des Suchers so mit
denen des Entfernungsmessers vereint werden, dass die Baulänge der Gesamtkombination
möglichst kurz wird, damit die GesamtanordnungauchbequemineinernormalenKleinbildkameraunterzubringen
ist.
Ein Ausführungsbeispiel der Neuerung ist zeichnerisch dargestellt.
Es zeigt : Abb. 1 einen Längsschnitt durch den Meß-Sucher, Abb. 2 das Gesichtsfeld
des Suchers bei Verwendung eines nur in der Sitte verspiegelten halbdurchlässigen
Basisreflektorsy Abb. 3 das gleiche Gesichtsfeld des Meß-Suchers wie in Abb. 2,
bei Verwendung eines in Streifenbreite in der Mitte verspiegelten halbdurohlässigen
Basisreflektors, Abb. 4 einen Schnitt A-B durch einen Glas- (Prismen-) Würfel mit
im Mittelfeld streifenförmiger
Zwischen Glaswürfel 6 und Prisma 8 ist in üblicher Weise das Entfernungsmesserobjektiv 9 vorgesehen, das die gleiche Brechkraft'Nie das Sucherobjektiv 1 besitzt.Between the glass cube 6 and the prism 8 is the range finder lens in the usual way 9 provided that the viewfinder lens 1 never has the same refractive power.
Die Wirkungsweise der Einrichtung ist derart, dass die Lichtbündel 10, 11 die beiden Entfernungsmesser-Teilbildern die in der Mitte des Meßsucher-Gesichtsfeldes (s. Abb-.. 2) in der kleinen Fläche (Entfernungsmesserbild) 12 zu sehen sind, entworfen. The operation of the device is such that the light beam 10, 11 the two rangefinder partial images in the middle of the rangefinder field of view (see Fig- .. 2) in the small area (rangefinder image) 12 are designed.
Der sich am Rande gegenüber dem Sucherbild hell abhebende Bildbegrenzungsrahmen
13 wird durch den Lichtbündel-Strahlengang 14 (s.Abb.1) erzeugt.
Deshalb hat in Abb.2 das Entfernungsmesserbild 12 zum Sucherfeld 15 eine komplementäre Färbung, während der Bildbegrenzungsrahmen 13 mit dem Sucherbild 15 die gleicheFarbehat. This is why the rangefinder image 12 in Fig. 2 faces the viewfinder field 15 a complementary coloring, while the image bounding frame 13 with the viewfinder image 15 has the same color.
Es ist verständlich, dass, damit der Bildbegrenzungsrahmen 13 sich
von dem Sucherbild farblich gut, d.h.
Da Debaucher nach dem Mischprinzip den Nachteil aufweisen, dass das
Sucherfeld relativ lichtschwach erscheint
Wenn sich das Auge des Beobachters so zentriert zum Meßsucher befindet,
dass es den Bildbegrenzungsrahmen 13 auf seinem ganzen Umfange deutlich erkennt,
dann liegt auch die fläche 16 dieses halbdurchlässigen Basisreflektors zentriert
zum Beobachterauge.
