ABSTRACT:
As a negative film having a multiplicity of perforations provided therein at equal intervals is being transferred, its perforations are detected to produce a corresponding pulse signal. The pulse signal is then fed to a controller which in turn calculates the number of clock pulses for each forty pulses of the pulse signal and determines a transfer distance per clock pulse. Meanwhile, the reference transfer distance is obtained from an interval between the perforations multiplied by forty. A difference between the actual transfer distance and the reference transfer distance is calculated and used for controlling the rotating movement of drive rollers.
