FEED RACK FOR FEEDING PHOTOSENSITIVE MATERIALS

摘要

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.
