Abstract
There is provided a photographic printer for transporting a photosensitive material in a reverse direction thereby improving the processing performance without wasting the photosensitive material, and a photographic printer exposure method. During automatic loading of the photographic paper (,) from the paper magazine (,) and during the paper replenishment, the gear train (,) is interrupted by an electromagnetic clutch (,) so that the second pair of transporting rollers (,) are freely rotatable. The first pair of transporting rollers (,) feeds the photographic paper from the paper magazine towards the exposure sections (,) and (,) by the driving force of motor (,). The freely rotatable second pair of transporting rollers, disposed between the first pair of transporting rollers and the exposure sections and guide the photographic paper. When a reverse transporting operation for rewinding the photographic paper is needed, the clutch and the solenoid of the electromagnetic clutch are simultaneously switched over, so that the driving force of motor (,) is transmitted to the second pair of transporting rollers via the second gear (,) and the gear train (,). As a result, the second pair of transporting rollers are rotated by motor (,) while the roller (,A) is rotated by motor (,), so that the photographic paper is transported toward the first pair of transporting rollers (,).
