Abstract

Bei einer fotografischen Kamera mit einem aus dem Kameragehaeuse ragenden Einstellknopf, welcher im Abstand von der Gehaeusewand und etwa parallel dazu eine Skala traegt, sowie einem zum Durchfuehren einer weiteren Kamerafunktion axial eindrueckbaren Betaetigungsstoessel, welcher aus einer aus der Gehaeusewand hervorstehenden Grundstellung in eine eingedrueckte Betaetigungsstellung bewegt werden kann, ist der Betaetigungsstoessel (5) nahe dem Umfang des Einstellknopfes (3) gelagert und auf der Stirnflaeche des Betaetigungsstoessels (5) ein Index (6) fuer die Skala (4) angeordnet.In a photographic camera with a protruding from the camera body adjustment knob, which at a distance from the Gehaeusewand and approximately parallel to a scale, as well as an axially performable for performing a further camera function Betetigungsstoessel which moves from a protruding from the Gehaeusewand basic position in a pressed Betetigungsstellung can be, the Betetigungsstoessel (5) is mounted near the circumference of the adjusting knob (3) and arranged on the end face of the Betetigungsstoessels (5) an index (6) for the scale (4).

Description

Die Anordnung hat die Wirkung, daß die Skala 4 und der Index 6 während der Grundstellung des Betätigungsstößels 5 zumindest annähernd in einer Ebene liegen und dort vom Fotografierenden betrachtet werden können. Eine nachteilig wirkende Parallaxe durch erhebliche Höhenunterschiede zwischen der Skala 4 und dem Index 6 tritt nicht auf, so daß dadurch bedingte Ungenauigkeiten beim Einstellen ausscheiden. Ein solcher Höhenunterschied zwischen Index 6 und Skala 4 tritt lediglich auf, wenn der Betätigungsstößel 5 zum Einleiten eines Rückspulvorganges niedergedrückt wird. Während des Rückspulens werden jedoch ohnehin keine Aufnahmen durchgeführt, die ein Bedienen des Einstellknopfes 3 erfordern. Mit dem Betätigen des Schnellspannhebels 2 kehrt der Betätigungsstößel 5 dann wieder in seine Grundstellung zurück, in welcher die Stirnfläche des Betätigungsstößels 5 wieder nahe der Ebene der Skala 4 liegt. Das Anbringen einer ausgesprochenen Indexmarke auf dem Betätigungsstößel 5 läßt sich vermeiden, wenn der Betätigungsstößel 5 zumindest im aus der Kamerawand 1 a ragenden Umfang farbig abweichend auf der Kamerawand 1 a ausgebildet ist.The arrangement has the effect that the scale 4 and the index 6 are at least approximately in one plane during the initial position of the actuating plunger 5 and can be viewed there by the photographer. A detrimental parallax by significant differences in height between the scale 4 and the index 6 does not occur, so that thereby excrete conditional inaccuracies in adjusting. Such a height difference between index 6 and scale 4 occurs only when the actuating rod 5 is depressed to initiate a rewinding operation. During rewinding, however, no recordings are made anyway, which require an operation of the adjusting knob 3. With the actuation of the quick release lever 2, the actuating plunger 5 then returns to its normal position, in which the end face of the actuating plunger 5 is again close to the level of the scale 4. The attachment of a pronounced index mark on the actuating plunger 5 can be avoided if the actuating plunger 5 at least in the out of the camera wall 1 a projecting circumference color differently on the camera wall 1 a is formed.

Claims

1. Photographic camera with a protruding from the camera housing knob, which carries at a distance from the housing wall and approximately parallel to a scale, as well as with an axially performable for performing another camera function actuating plunger, which consists of a protruding from the housing wall basic position in a depressed operating position is movable, characterized in that the actuating plunger (5) is mounted near the periphery of the adjusting knob (3) and on the end face of the actuating plunger (5) an index (6) for the scale (4) is arranged.

2. Photographic camera according to claim 1, characterized in that the actuating plunger (5) protrudes in its basic position to approximately in the plane of the scale (4) from the housing wall 1 a.

3. Photographic camera according to claim 1 or 2, characterized in that the index is designed as a mark (6).

4. Photographic camera according to claim 1 or 2, characterized in that the actuating plunger (5) is different in color from the housing wall (1 a) is formed.

Field of application of the invention

The invention relates to a photographic camera with a protruding from the camera housing knob, which carries at a distance from the housing wall and approximately parallel to a scale, as well as with an axially depressable for performing another camera function actuating plunger, which consists of a protruding from the housing wall basic position in a pressed-in actuating position is movable.

Characteristic of the known technical solutions

Known cameras of this type have adjusting knobs, the haptic condition quite far from the camera wall protrude, which ensures ease of use is guaranteed. In a known arrangement (DE-OS 2453955) is arranged on the parallel to the camera wall end face of such an adjustment knob required for the defined setting scale. However, when setting the scale over a fixed index index, there will be some parallax between the scale and the index due to the large distance, which may result in inaccurate adjustments.

Purpose of the invention

The invention aims to improve the setting accuracy.

Essence of the invention

The object of the invention is an adjustment device with the purpose of corresponding novel arrangement of scale and associated index. According to the invention this is achieved in that the actuating plunger is mounted near the periphery of the adjusting knob and an index for the scale is arranged on the end face of the actuating plunger. Preferably, the actuating plunger protrudes in its basic position to approximately in the plane of the scale of the housing wall. The index is expediently designed as a trademark. According to a special arrangement, the actuating plunger is differently colored from the housing wall.

Embodiment of the invention

The invention is explained with reference to an illustrated and described embodiment. Show it

1: the overall view of a camera,

Fig. 2: the front view in the region of the adjusting knob and

3: the top view in the region of the adjustment knob.

On the camera body 1, in addition to the so-called quick release lever 2, the adjusting knob 3 is rotatably arranged for selecting different exposure times. The knob 3 carries on its upper face a scale 4 with values for different exposure times and automatic and flash recording. Because of the good grip of the knob 3 is tight, so that the scale, 4 has a relatively large distance from the upper camera wall 1 a. Near the periphery of the adjusting knob 3, the actuating plunger 5 is arranged axially pressed into the camera housing 1, which must be moved in the case of rewinding the exposed film. On the end face of the actuating plunger 5, the index 6 is provided, according to which the values of the scale 4 are adjustable. The end face of the actuating plunger 5 protrudes as far as possible to the level of the scale 4 zoom.
