Description

Klappkamera mit besonderem Sucherobjektiv Zusatz zum Patent 645 078 Die Erfindung betrifft die weitere Ausgestaltung der Kamera nach dem H#auptpa:tent zum Zwecke, einen Ausgleich der Parallaxe zu erzielen. Gemäß der Erfindung wird zum Ausgleich der Parallaxe eine am Kameradeckel, dem Träger der Einstellebene, angelenkte Platte verwendet. Dieselbe wird von dem Objektivträger durch Anschlag oder gelenkige Verbindung mitbewegt. An dieser Platte greift ein Rahmen ein, welch-er die Bildbegrenzung oder Mattscheibe trägt und von ihr mitbewegt wird, und zwiar je weniger, je näher der Eingriff des Rahmens am Gelenkpunkt der Platte liegt. Dadurch wird zum Ausgleich der Parnllaxe eine von der Einstellbewegung verschiedene Bewegung der Bildbegrenzung erreicht.Folding camera with a special viewfinder lens Addition to patent 645 078 The invention relates to the further configuration of the camera according to the main patent for the purpose of compensating for the parallax. According to the invention, a plate hinged to the camera cover, the carrier of the adjustment plane, is used to compensate for the parallax. The same is moved along with the lens carrier by means of a stop or an articulated connection. A frame engages on this plate, which carries the picture border or ground glass and is moved along with it, and the less the closer the engagement of the frame is to the hinge point of the plate. As a result, a movement of the image boundary that differs from the adjustment movement is achieved to compensate for the paralysis.

Auf der Zeichnung sind einige Ausführungsbeispiele dargestellt: Die Abbildung zeigt die Plattep am Kameradeckelk angelenkt, welche durch eine nicht gezeichnete Feder aufgestellt wird bis zum Eingriff des Rahmensr, welcher die Bildbegrenzung oder die Mattscheibe trägt oder Abdeckungsleisten bewegt. Der Objektivträgert nimmt vermittels der Plattep den Ra,1-imeiir mit. Der Balgenb reicht von der'Aufnahinekammer bis zur Einstellebene -und hat eine Zwischenwandz. Außerhalb des Kameragehä.:uses ist er nach oben um un-,e%hr den Abstand des Kameradeckels vom Objektivträgerende verlängert. Er ist oben offen -und kann vorn geschlossen sein, mit den entsprechendenÖffnungen für die Objektive. o ist das Sucherobjektiv, o' das Aufnahmeobjektiv, /t das Kameragehäuse.Some exemplary embodiments are shown in the drawing: The illustration shows the plate hinged to the camera cover, which by a not drawn spring is set up until the engagement of the frame, which the picture border or wearing the ground glass or moving cover strips. The lens carrier takes by means of the plate the Ra, 1-imeiir with. The bellows extends from the receiving chamber up to the setting level -and has a partition wall. Outside the camera case: uses if it is upwards by approx. e% hr the distance between the camera cover and the end of the lens mount extended. It is open at the top - and can be closed at the front, with the corresponding openings for the lenses. o is the viewfinder lens, o 'the taking lens, / t the camera housing.
