There is provided an improved rack for feeding photosensitive materials, which is so adapted that an operator can turn its feed rollers without soiling his hand. A vertically-extending roller driving shaft is rotatably provided outside of a rack body. A sprocket carries a bevel gear which is coaxial with the sprocket and meshes with a bevel gear fixed to the top end of the roller driving shaft. The bevel gear mounted on the sprocket has a cylindrical member. Outside of the cylindrical member is provided a knob. A spring is mounted to bias the knob away from the sprocket. The knob has a control sleeve which can be moved to a position where it surrounds the sprocket. After moving the control sleeve to this position, the knob is turned by hand to turn the roller driving shaft.
A rack fur feeding photosensitive materials comprising a rack body, a pair of rack plates secured to the rack body, rollers provided between said pair of rack plates for feeding photosensitive materials, a driving wheel provided outside of one of said rack plates, a torque transmission wheel mounted to be coaxial with and rotatable together with said driving wheel, a torque transmission means for transmitting the rotation of said torque transmission wheel to said rollers, said torque transmission wheel having a guide sleeve, a control sleeve mounted on said guide sleeve so as to be unrotatable and slidable between a first position where it surrounds said driving wheel and a second position where it is away from said driving wheel, and an engaging means for preventing axial movement of said control shaft when it is in said first position.
