PURPOSE: To take a normal size picture and a wide screen picture with one camera by constituting a film so as to make the second longitudinal direction of an aperture coincident with the direction of a film path, when the film passes through the aperture.

CONSTITUTION: The film 28 is separated from a sprocket 68 and then passes through a sprocket 82 having 24 teeth on the upstream side. But after that, the film 28 guided by a film holding member 86 at this time passes through a straight path from the outer periphery of the sprocket 82, and then, an aperture plate assembly 92 away from an aperture 91 by about 0.006-0.008 inch and is fed to a sprocket 94 having 16 teeth on the downstream side. The film 28 is guided around the sprocket 94 by film holding members 98 and 100. After that, the film 28 is fed to a sprocket 104 having 16 teeth and held at the position of the sprocket 104 by film holding members 108 and 110.
