ABSTRACT:
A sheet conveyer includes a feed roller, a pressure roller, a first guide and a second guide. The guides define a traveling passage between them for a sheet of paper to be sent to the nip between the rollers. The guides are positioned in such a manner that the passage narrows toward the nip. Even if a sheet of paper is wavy widthwise, it is flattened when sent to the nip. At least a front end portion of the second guide is made of material which can elastically deform toward the nip. The front end portion extends to a position very near to the nip. Even if the direction in which a sheet of paper is conveyed changes at a sharp angle just before the sheet reaches the nip, the elastic portion makes the sheet turn or bend gently, preventing it from turning or bending sharply.
