Patent number: 7114867Abstract: In a recording apparatus including an inversion unit for inverting a recording sheet recorded on a side in a recording unit by conveying along a predetermined path and returning the recording sheet to the recording unit, the possibility of peeling of recording material from the recorded surface or re-deposition of the recording material onto the recording sheet can be reduced. The recording sheet subjected to recording on a side in the recording unit having a recording head is conveyed to the inversion unit, which includes, at a recorded side of the recording sheet, two both-side rollers which are driven and are formed of an elastic material, and, at a non-recorded side, two both-side pinch rollers which are formed of a non-elastic material. The inversion unit conveys the recording sheet along a turnaround path with the recorded side inside, thereby inverting and returning the recording sheet to the recording unit.Type: GrantFiled: April 13, 2004Date of Patent: October 3, 2006Assignee: Canon Kabushiki KaishaInventors: Tetsuyo Ohashi, Koya Iwakura
