ABSTRACT:
Driving sources of a reversing section roller and a sheet feeding roller are made common, a drive transmission mechanism to the reversing section roller is provided with clutch means for starting and stopping synchronous rotation after a predetermined rotation, and a degree of freedom in control is enhanced by properly bringing the reversing section roller into a halted state as necessary, thereby realizing reduction in load on the driving source, reduction in noises, and reduction in the size of the apparatus and cost. The apparatus is provided with clutch means, which starts synchronous rotation of the reversing section roller with the sheet feeding roller is started in a period of time from a start of a drive of the sheet feeding roller until nipping of a recording medium by the reversing section roller, after recording is performed onto a front surface, and stops the synchronous rotation of the reversing section roller with the sheet feeding roller in a period of time from release from the reversing section roller until finishing of a sheet discharge operation, after the recording medium from a sheet reversing section is nipped by the sheet feeding roller again.
