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.
Claims20
A recording-medium transport device having a plurality of rollers with an endless transport belt engaged therearound for transporting a recording medium, said endless transport belt having a span disposed between a distal roller and a proximal roller, said span having a transporting side for bearing and transporting thereon a recording medium on which image formation means forms an image and a back side, said recording-medium transport device comprising:
- a pair of pinch rollers separate from said plurality of rollers to pinch the recording medium together with said endless transport belt and thus transport the recording medium toward the image formation means, wherein said pair of pinch rollers includes an outer pinch roller and an inner pinch roller, wherein said outer pinch roller contacts the upper surface of the transporting side of the span of the endless transport belt and said inner pinch roller contacts the back side of the span of said endless transport belt.
An image recording system for recording an image on a recording medium, wherein the image recording system comprises:
- a recording-medium transporting device;
- and
- an image formation means,
- wherein said recording-medium transport device, having a plurality of rollers with an endless transport belt engaged therearound for transporting a recording medium, said endless transport belt having a span disposed between a distal roller and a proximal roller, said span having a transporting side for bearing and transporting thereon a recording medium on which image formation means forms an image and a back side, comprises:
- a pair of pinch rollers separate from said plurality of rollers to pinch the recording medium together with said endless transport belt and thus transport the recording medium toward the image formation means, wherein said pair of pinch rollers includes an outer pinch roller and an inner pinch roller, wherein said outer pinch roller contacts the upper surface of the transporting side of the span of the endless transport belt and said inner pinch roller contacts the back side of the span of said endless transport belt.
