Description
Belichtungsmesser für photographische Zwecke Die Neuerung betrifft das Gehäuse zur Unterbringung des Belichtungsmesser-Messwerks.Light meter for photographic purposes The innovation concerns the housing to accommodate the light meter measuring mechanism.
Es ist bekannt, das Messwerk für lichtelektrische Belichtungsmesser in einem staub-und feuchtigkeitsdichten Gehäuse unterzubringen, dessen Deckplatte wenigstens teilsweise aus durchsichtigem Material gefertigt ist. Dies ergibt die Möglichkeit, den Zeigerausschlag und die Skala im geschlossenen Gehäuse betrachten zu können. Bei Messinstrumenten, welche zum Zwecke der Berücksichtigung von Aufnahmefaktoren drehverstellbar sind, ist es bekannt, das Gehäuse mit dem Antrieb für das drehverstellbare System abdichtend zu durchdringen.It is known the measuring mechanism for photoelectric exposure meters to be accommodated in a dust- and moisture-proof housing, its cover plate is at least partially made of transparent material. This gives the Possibility of viewing the pointer deflection and the scale in the closed case to be able to. In the case of measuring instruments which are used for the purpose of taking into account absorption factors are rotatable, it is known that the housing with the drive for the rotatable To penetrate the system in a sealing manner.
Der Mangel dieser Vorrichtung wird darin gesehen, dass ein in sich geschlossenes Gehäuse lediglich für den Antrieb an einer oder mehreren Stellen durchbrochen wird und damit den staub-und feuchtigkeitsdichten Abschluss in Frage stellt.The shortcoming of this device is seen in the fact that a closed housing only perforated for the drive in one or more places and thus calls into question the dust- and moisture-proof closure.
Die Beseitigung dieses Mangels ist die Aufgabe der Neuerung.The task of innovation is to remedy this deficiency.
Bei dem Messwerk eines photoelektrischen Belichtungsmessers, welches in einem Gehäuse untergebracht ist, wird diese neuerungsgemäss dadurch gelöst, dass zum Zwecke der Einstellung bzw. Berücksichtigung von Aufnahmefaktoren wie Filmempfindlichkeit, Blende, Belichtungszeit oder dergleichen, insbesondere durch Zeigernachführung, das Gehäuse einschliesslich Messwerk gedreht oder geschwenkt werden kann. Die Mittel zur Lagerung, zur Steuerung bzw. zum Antrieb des Gehäuses, sind vorzugsweise an diesem angeordnet und/oder werden von ihm selbst gebildet.In the case of the measuring mechanism of a photoelectric light meter, which is housed in a housing, this is achieved according to the innovation in that for the purpose of setting or taking into account recording factors such as film speed, Aperture, exposure time or the like, in particular through pointer tracking, the housing including the measuring mechanism can be rotated or swiveled. The means for storage, for control or for driving the housing, are preferably on this arranged and / or are formed by himself.
Weitere Einzelheiten der Neuerung sind der Beschreibung eines Ausführungsbeispiels, ohne sich jedoch darauf zu beschränken, sowie den Schutzansprüchen zu entnehmen.Further details of the innovation are the description of an exemplary embodiment, however, without being limited to this, as well as being inferred from the claims for protection.
Die zeichnerische Darstellung zeigt in der Abb. l einen Schnitt durch die Seitenansicht des Gehäuses mit dem darin gelagerten Messwerk, Abb. 2 die perspektivische Ansicht des Messwerkgehäuses.The graphic representation shows in Fig. 1 a section through the side view of the housing with the measuring mechanism mounted in it, Fig. 2 the perspective View of the measuring mechanism housing.
