20080205954 | IMAGE RECORDING APPARATUS - In an image recording apparatus according to an aspect of the invention, a recording medium is allowed to be conveyed on a conveying path. An inversion guide portion connects a first portion of the conveying path positioned downstream of a recording unit to a second portion of the conveying path positioned upstream of the recording unit. A path changeover unit is disposed at the first portion of the conveying path and swingable between a recording medium discharge position and a recording medium inversion position. When the path changeover unit is positioned at the recording medium discharge position, the forward rotation of the roller pair allows the recording medium to be sent to a discharge portion. When the path changeover unit is positioned at the recording medium inversion position, the rearward rotation of the roller pair allows the recording medium to be sent to the inversion guide portion. | 08-28-2008 |
