Abstract
A discharging unit has multiple discharging rollers for transporting sheets downstream from a recording head in the direction of transporting, arrayed in the direction of transporting. Of the multiple discharging rollers, a second discharging roller disposed farthest downstream in the sheet transporting direction is formed with higher precision than a first discharging roller disposed further upstream.
Claims12
A recording apparatus for recording on recording sheets by recording means, said recording apparatus comprising:
- a transporting roller for transporting the recording sheets, said transporting roller being positioned upstream of the recording means relative to the transporting direction;
- a proximal discharging roller for transporting the recording sheets, said proximal discharging roller being positioned downstream of the recording means relative to the transporting direction and having deviations from a nominal circumference within a first range;
- and
- a distal discharging roller disposed downstream of said proximal discharging roller relative to the transporting direction, said distal discharging roller having deviations from a nominal circumference within a second range and being of higher precision than said proximal discharging roller in that the second range is less than the first range.
A method of manufacturing a recording apparatus for recording on recording sheets by recording means, said method comprising the steps of:
- forming a transporting roller for transporting the recording sheets, and positioning the transporting roller upstream of the recording means relative to the transporting direction;
- forming a proximal discharging roller for transporting the recording sheets, and positioning the proximal discharging roller downstream of the recording means relative to the transporting direction;
- and
- forming a distal discharging roller in a process of higher precision than that of a process for forming the proximal discharge roller, and positioning the distal discharging roller downstream of the proximal discharging roller relative to the transporting direction.
