PURPOSE: To surely and orderly take up a microfilm as a longsized material without damaging the film by winding the film on a take-up reel with stable rotation.

CONSTITUTION: The film guide surface of a guide arm 2 for guiding the film F to a take-up reel 3 is formed asymmetrical with the central plane Z-Z of the inside walls of a pair of side plates 12, 12 of the take-up reel 3. Even if the transported film f is nabbed at both ends in the transverse direction C thereof by claw parts 12a, 12a, which are projecting parts of the take-up reel 3, the film F is twisted by being pressed to the asymmetric guide surfaces of the guide arm 2 and both ends of the film F are retreated from the claw parts 12a, 12a to restore the normal taking-up state. The film F is thus surely and orderly taken up on the reel 3.
