<p>PURPOSE:To transport a sheet corrected by applying rigidity to the sheet corresponding to detachement and attachement of a cover member and to normally transport a sheet without any rigidity applied to the sheet by detachably disposing the cover member having a sheet guide portion formed at a part thereof among plural pairs of transport rollers. CONSTITUTION:A part 8 of a paper discharge cover 8 detachably or rotatably disposed on an apparatus main body has a function for further guiding a sheet fed from a sheet transport path 10, and the part 8 is extended between lower paper discharge rollers 91, 91'. The above part 8 is disposed in such a manner that the uppermost portion thereof is positioned above nip portions 93, 93' between upper paper discharge rollers 92, 92' and the lower paper discharge rollers 91, 91. In this arrangement, a sheet transport path which is waveform in section and alternately rises and falls is formed so that apparent rigidity is applied to a sheet transported in the transport path to remove curling of the sheet. The paper discharge cover 8 is detached not to form the waveform of a sheet and apply rigidity to the sheet, so that the sheet is normally transported.</p> |
