Abstract
An ink jet recording apparatus includes a transporting roller for transporting a recording sheet to a recording section of the apparatus; a pre-biasing roller disposed upstream of the transporting roller relative to the direction of transportation of the recording sheet and arranged to impart to the recording sheet such a tendency that both lateral end portions of the recording sheet are curled away from a recording head; and a platen having a guide surface for guiding and supporting the recording sheet. An aperture is formed in the platen so as to oppose the recording head and so as to extend in the width direction of the recording sheet. The aperture has a predetermined width and a sloping surface so as to extend downward in the direction of transportation of the recording sheet.
Claims30
A recording apparatus having recording means for effecting recording on a recording medium at a recording zone, said recording apparatus comprising:
- a transporting roller for transporting the recording medium to the recording zone;
- a pre-biasing roller disposed upstream of said transporting roller and arranged to impart to the recording medium a curling tendency enabling recording to be performed;
- and
- a guide member disposed to face said pre-biasing roller and interacting with said pre-biasing roller to impart the curling tendency to the recording medium.
A recording apparatus having recording means for effecting recording on a recording medium at a recording zone, said recording apparatus comprising:
- a transporting roller for transporting the recording medium to the recording zone;
- a pre-biasing roller disposed upstream of said transporting roller relative to the transporting direction of the recording medium and arranged to provide the recording medium with a tendency such that left and right end portions of the recording medium are biased away from the recording means;
- and
- a guide member disposed to face said pre-biasing roller and interacting with said pre-biasing roller to impart the curling tendency to the recording medium.
