Abstract
A mechanism to be used in 35 mm film format still cameras, which pre-winds a roll of unexposed film entirely by motor to the unexposed film chamber provided in the camera immediately after the camera back door has been closed with the unexposed film loaded inside without using any expensive electric circuits and devices like a CPU, and of which the pre-winding setting can be changed manually by hand to the winding setting (picture taking setting) for picture taking after the pre-winding has been completed, and which can be reset to the pre-winding setting of the mechanism automatically but mechanically when the camera back door is opened again after the film has been exposed, wound back into and stored in the film cartridge.
