Abstract

PURPOSE: To prevent film from being wound in telescopic form and linear form by making the outside diameter of one end part of a film winding member larger than the outside diameter of the other portion.
CONSTITUTION: The film housed in a patrone chamber is unrolled by every fixed length by a sprocket and the leading end small-width part A of the film is wound to a winding member 9 by way of the rubber roller 29 of the 2nd pressure member 11 and the roller 24 of the 1st pressure member 10. Here, the member 9 consists of an inside barrel having a flange 12a and an outside barrel 13 of high friction elastic material making close contact therewith. The outside diameter of the end part 13a closer to the flange 12a is made slightly larger than the outside diameter of the other part 13b. Because of this large-diameter part 13a, the friction force of the film differs and the downward thrust force acts upon the leading end small-width part A, thus the winding is started in the state that it is held pressed to the flange 12a. Thereby, the film is advanced in the linear track and is prevented from being wound in telescopic form or linear form.
