Abstract

PURPOSE:To prevent bending of film by spraying air to the film. CONSTITUTION:Compressed air 2 is sprayed from a compressor 3 to a film F which is conveyed by a conveying roller R from the lower part. thus the film F is pressed to a film holding plate A, and accordingly, bending of the film is prevented. As a result, a high-contrast picture is obtained with no out-of-focus phenomenon and without impairing the film surface in case an exposure is carried out by an exposure device C.
