Abstract
A recording apparatus includes a recording section, a convey section, and a discharge section. The invention further includes an urging device for urging a pinch roller against a recording sheet, an urging force controller for controlling an urging force of the urging device, and a detector for detecting that a trail end of the recording sheet is conveyed to a predetermined position disposed upstream of a position where the trail end of the recording sheet leaves the pinch roller. The urging force controller reduces or releases the urging force of the urging device on the basis of a detection result from the detector, thereby eliminating the force of the pinch roller acting on the trail end of the recording sheet. The apparatus prevents the conveying accuracy of the recording sheet from being adversely affected.
Claims11
A recording apparatus including a recording portion for effecting recording on a recording sheet, said recording apparatus comprising:
- convey means for conveying the recording sheet when recording is being effected on the recording sheet in said recording portion as well as for conveying the recording sheet to said recording portion by pinching the recording sheet between a pinch roller and a convey roller;
- discharge means for discharging the recording sheet, said discharge means being disposed downstream of said recording portion;
- urging means for urging said pinch roller against the recording sheet;
- urging force controlling means for controlling an urging force of said urging means;
- and
- detecting means for detecting a trailing end of the recording sheet, said detecting means being disposed upstream of said convey means,
- wherein on the basis of a detection result output from said detecting means, said urging force controlling means reduces the urging force of said urging means when the trailing end of the recording sheet, on which recording is being effected in said recording portion, passes said convey means.
