PURPOSE: To facilitate the assembly of a rack for conveying a film.

CONSTITUTION: A bevel gear 20 is fixed to the end part of a driving shaft 16 provided at the upper part of a rack body, and bevel gears 30 are fixed to the sprocket shafts 28 of plural sprockets 29 provided vertically in the rack body. Plural bevel gears 35 meshed with the respective bevel gears 20, 30 are fixed in the in-phase state of teeth to a torque transmission shaft 34 extended vertically in the rack body. The bevel gears 20, 30, 35 and the sprockets 29 are to have the same number of teeth, and the driving shaft 16, the sprocket shafts 28 and the torque transmission shaft 34 are integrated into the rack body so that the respective bevel gears 20, 30, 35 are meshed. The teeth of plural sprockets 29 thereby face the fixed direction.
