Abstract
A passing movement analyzer is responsive to a pulse signal from a data reader to calculate the time of passing movement of a negative film. The passing of one frame of the negative film is considered detected when two identification codes of the film are read. When the two identification codes are detected by the passing movement analyzer, a drive signal of a driver contains a number of pulses which differs from that of a standard number, and a correction calculator determines that a transfer error exists and adjusts the pulse setting of the drive.
