  • Recording-medium transport device
    Patent number: 6575459
    Abstract: A recording-medium transport device includes a pair of pinch rollers arranged closer to a printing head than to a subordinate roller and pinching and transporting a belt and a sheet of paper toward the printing head. The pair of pinch rollers can pinch the sheet of paper together with the belt, while maintaining the belt flat. As such, an image of high quality can be formed, e.g., printed on the recording medium. Furthermore, the recording medium does not divert from a transporting path. Thus reliable image formation can be achieved.
