CA 2167435

A photographic processing apparatus includes a main drive roller mechanism for transporting a photosensitive material in forward and reverse transport directions along a transport passage. The apparatus also includes forward and reverse drive roller mechanisms for assisting the main drive roller mechanism. The forward and reverse drive roller mechanisms are disposed upstream of the main drive roller mechanism relative to the forward transport direction. At least the forward and reverse drive roller mechanisms are supplied with power by a common drive source. The forward drive roller mechanism includes a first one-way clutch mechanism for restricting the rotational force supplied from the drive source when the photosensitive material is transported reversely. The reverse drive roller mechanism includes a second one-way clutch mechanism for restricting the rotational force supplied from the drive source when the photosensitive material is transported forwardly.
