Abstract
An original reading and conveying apparatus comprises a transparent plate arranged in a reading area of a conveying passage for conveying an original, and a pressure conveying roller arranged to confront the transparent plate and be pushed toward the transparent plate. At least a circumferential surface of a roller portion the pressure conveying roller is covered with a synthetic resin layer. An original conveying roller is arranged at the downstream side, as viewed in the original conveying direction, of the pressure conveying roller and is rotationally driven by a driving force coming from the pressure conveying roller.

An original reading and conveying apparatus comprising:
- a transparent plate arranged in a reading area of a conveying passage for conveying an original and a pressure conveying roller arranged to confront the transparent plate and be pushed toward the transparent plate,
- at least a circumferential surface of a roller portion of the pressure conveying roller being covered with a synthetic resin layer,
- an original conveying roller for conveying the original arranged at a downstream side, as viewed in an original conveying direction, of the pressure conveying roller, which original conveying roller is rotationally driven by a driving force coming from the pressure conveying roller;
- the roller portion of the original conveying roller being axially shorter than the axial extent of the roller portion of the pressure conveying roller;
- and
- a part of the roller portion of the pressure conveying roller being provided with a small diameter portion having a smaller external diameter than that of the remaining part, and a driving force transmission mechanism for transmitting the driving force to the original conveying roller being interposed between the small diameter portion and the original conveying roller.
An original reading and conveying apparatus comprising:
- a transparent plate arranged in a reading area of a conveying passage for conveying an original and a pressure conveying roller arranged to confront the transparent plate and be pushed toward the transparent plate,
- wherein at least a circumferential surface of a roller portion of the pressure conveying roller is covered with a synthetic resin layer, and
- wherein an original conveying roller for conveying the original is arranged at a downstream side, as viewed in an original conveying direction, of the pressure conveying roller, which original conveying roller is rotationally driven by a driving force coming from the pressure conveying roller.
