When a film is loaded and the film advance lever is wound up, the
counter roller (6- 93) is turned to the arrow direction by the film.
o
As the counter roller (6- 93) turns the counter dial (3- 51) is advanced.
o
The film advance lever can be wound up successively until the 1st
frame is indicated by the exposure counter.
o
When the film is wound up to the 1st frame, the edge of the counter
dial disengages with the rising portion (A) of the lever (3- 121),
allowing the lever (3- 121) to turn to the arrow direction.
o
When the disc (3- 85) turns and the groove is coincided with the lever
(3- 121), the lever drops into the groove, and the lever (6- 64) engages
with the ratchet wheel (6- 72).
o
When the ratchet wheel (6- 72) stops, the film taking- up force acts
as a friction, causing the film taking- up (advance) to stop.
The film advance lever can be wound up continuously until the
swing lever (3- 78) disengages with the ratchet even after the film stops.
