Bei anderen   solchen bekannten Verschlüssen kommt wohl ein Rastenrad zur   Verwendung,   dieses wird aber nicht durch ein Laufwerk bewegt. sondern vom Photographen selbst. Ausserdem ermöglichen die Zähne dieses   bekannten Rastt'nrades infolge, ihrer verschiedenen Breite   nur ein Ändern der Expositionszeiten.

   Release of the lock can be set separately. In other such known closures a ratchet wheel is used, but this is not moved by a drive. but by the photographer himself. In addition, the teeth of this well-known ratchet wheel only allow the exposure times to be changed due to their different widths. The photographer can, because the ratchet wheel does not turn automatically. Do not leave the machine to take photos of yourself. But this should be done with the
