Abstract
A recording apparatus comprising a platen for supporting a sheet at a recording area, feeding means for feeding the sheet to the platen, recording means for recording an image on the sheet at the recording area, and an urging member disposed at a downstream side of the recording area and adapted to urge the sheet against the platen. The urging member has an urging surface for urging the sheet against the platen when the recording means is recording the image on the sheet.
Claims78
A recording apparatus, comprising:
- a guide for supporting a sheet at a recording area thereof;
- a feeding rotary member for feeding the sheet to said guide;
- a recording head for recording an image on the sheet at the recording area by adhering an ink to the sheet;
- and
- an urging plate for urging the sheet against said guide, said urging plate having a water repellant surface abutted to the sheet and being disposed downstream of the recording area, and said urging plate assuming one of a first mode to urge the sheet against said guide while said recording head is adhering the ink to the sheet and a second mode not urging the sheet against said guide means while said recording head is adhering the ink to the sheet.

A recording apparatus, comprising:
- a platen for holding a sheet at a recording area thereof;
- first feeding means disposed upstream of said guide for feeding the sheet to said platen;
- recording means for recording an image on the sheet at the recording area by adhering an ink to the sheet;
- second feeding means disposed downstream of said platen for feeding the sheet on which the image is recorded by said recording means;
- a first urging plate disposed between the recording area and said first feeding means for urging the sheet against said platen;
- and
- a second urging plate disposed between the recording area and said second feeding means for urging the sheet against said platen;
- mode switching means for switching modes of said first urging plate and said second urging plate between a first mode and a second mode;
- wherein said first and second urging plates assume one of the first mode to urge the sheet against said platen while said recording head is adhering the ink to the sheet and the second mode not urging the sheet against said platen while said recording head is adhering the ink to the sheet.
