A reading machine for bubble chamber photographs has a horizontal film table across which film is lengthwise advanced, frame by frame, from a supply reel at one side of the table to a takeup reel at the other side thereof, and to which the film is flatwise clamped for horizontal movement with the table. Carriers for the reels, extending below the table at opposite sides thereof, are mounted for motion transverse to film length and are driven in such motion in unison with the table to avoid twisting the film. |
