Abstract
An image input-output apparatus includes a housing which is internally provided with a common transfer path. Further, the housing internally incorporates a transfer mechanism for selectively transferring a document and a recording paper along the common transfer path, a combination of an image reading light source and an image sensor for optically reading an image of the document moving along the common transfer path, and a printing unit for printing an image on the recording paper moving along the common transfer path. The width of the recording paper may be detected by a combination of a width detecting light source and the image sensor.
Claims17
An image input-output apparatus comprising:
- a common transfer path;
- a transfer mechanism for selectively transferring a document and a recording paper along the common transfer path;
- a reading unit for optically reading an image of the document moving along the common transfer path, the reading unit including an image reading light source and an image sensor;
- a printing unit for printing an image on the recording paper moving along the common transfer path;
- and
- a paper width detector provided upstream from the printing unit for detecting a width of the recording paper,
- wherein the paper width detector includes a combination of the image sensor and a width detecting light source arranged in opposed relationship to the image sensor, and
- wherein the image reading light source and the image sensor are arranged on an image reading side of the common transfer path, the width detecting light source being arranged on an opposite side of the common transfer path.
An image input-output apparatus comprising:
- a common transfer path;
- a transfer mechanism for selectively transferring a document and a recording paper along the common transfer path;
- an image reader for optically reading an image of the document moving along the common transfer path, the image reader including an image reading light source and an image sensor;
- a document width detector for detecting a width of the document before the document is transferred to the image reader;
- a printing unit provided downstream from the image reader for printing an image on the recording paper moving along the common transfer path;
- and
- a paper width detector provided upstream from the printing unit for detecting a width of the recording paper,
- wherein the paper width detector includes a combination of the image sensor and a width detecting light source arranged in opposed relation to the image sensor, and
- wherein the image reading light source and the image sensor are arranged on an image reading side of the common transfer path, the width detecting light source being arranged on an opposite side of the common transfer path.

- a document width detector for detecting a width of the document before the document is transferred to the image reader;
- a printing unit provided downstream from the image reader for printing an image on the recording paper moving along the common transfer path;
- a paper width detector provide d upstream from the printing unit for detecting a width of the recording paper, the paper width detector including a combination of the image sensor and a width detecting light source arranged in opposed relation to the image sensor;
- and
- light source switching means for selectively turning on or off the image reading light source and the width detecting light source,
- wherein the light source switching means turns on the image reading light source while turning off the width detecting light source when the document is transferred along the common transfer path, and
- wherein the light source switching means turns on the width detecting light source while turning off the image reading light source when the recording paper is transferred along the common transfer path.
