Frame Counter

The frame counter is an additive type

which counts one frame every time the film
advance lever winds the film. When the
camera's back cover is opened, the frame
counter automatically resets itself to the "S"


While rewinding film, the frame counter

counts back the frame numbers. The starting

position "S", 0, and the even numbers 2 to 38

are displayed by the counter. Numbers 20 and

36 are marked in orange to call your attention

to the end of film cartridges such as are today

commercially available. The frame counter

cannot count higher than 38.
