Abstract
A support roller disposed on a side of a case main body of a facsimile apparatus is supported by a pair of right and left end holding members with associated coil springs for urging the support roller upward in an elevatable and oscillatable manner. A nose portion of a curl eliminating plate fixed to the lower surface of an upper cover member, which may be opened and closed, is disposed close to the circumferential surface of the support roller when the upper cover member is closed. When the upper cover member is closed, the support roller is inhibited from moving in either direction with respect to a feed path by restricting members projected downward from the upper cover member. The combination of the support roller and the nose portion of a curl eliminating plate define an S-shaped path through which the paper is fed to eliminate curl.
