Abstract

An image reading device reads an image of an original document and includes a conveyance roller, an image reading section, a first determination section, a second determination section, and a conveyance stopping section. The conveyance roller conveys the original document. The image reading section reads the image of the original document. The first determination section determines whether or not the original document has a punched hole based on the image read by the image reading section. The second determination section determines, upon determination that the original document has the punched hole, whether or not the punched hole is to travel on an edge of the conveyance roller. The conveyance stopping section stops conveyance of the original document upon determination that the punched hole is to travel on the edge of the conveyance roller.

Claims

1. An image reading device for reading an image of an original document, comprising:

a conveyance roller configured to convey the original document;

an image reading section configured to read the image of the original document;

a first determination section configured to determine whether or not the original document has a hole based on the image read by the image reading section;

a second determination section configured to determine, upon determination that the original document has the hole, whether or not the hole is to travel on an edge of the conveyance roller, and

a conveyance stopping section configured to stop conveyance of the original document upon determination that the hole is to travel on the edge of the conveyance roller.

2. The image reading device according to claim 1, further comprising:

a conveyance guide configured to guide conveyance of the original document, the conveyance guide having a projection; and

a third determination section configured to determine, upon determination that the original document has the hole, whether or not the hole is to travel on the projection of the conveyance guide, wherein

the conveyance stopping section stops conveyance of the original document upon determination that the hole is to travel on the projection of the conveyance guide.

3. The image reading device according to claim 1, further comprising

a notification section configured to externally notify that the original document has the hole, and therefore conveyance of the original document has been stopped, in response to the conveyance stopping section stopping conveyance of the original document.

4. The image reading device according to claim 1, wherein

the original document includes a sheet whose opposite sides have images formed thereon,

the image reading section is preset to perform image reading on both the sides of the sheet of the original document, and

the image reading device further comprises a setting changing section configured to change, upon determination that the original document has the hole, settings such that image reading is performed on one of the sides of the sheet of the original document.

5. The image reading device according to claim 4, wherein

the original document includes a plurality of the sheets,

the image reading section is preset to perform image reading consecutively on the sheets of the original document, and

the setting changing section changes, upon determination that the original document has the hole, settings such that image reading is performed on the sheets of the original document on a sheet-by-sheet basis.

6. The image reading device according to claim 1, wherein

the hole is a punched hole, and

the first determination section determines whether or not the original document has the punched hole based on whether or not the image of the original document includes a black circular image.

7. The image reading device according to claim 1, wherein

the conveyance roller includes a plurality of narrow rollers, and

the second determination section determines whether or not the hole is to travel on an edge of at least one of the narrow rollers.

8. The image reading device according to claim 2, wherein

the conveyance guide has a plurality of the projections, and

the second determination section determines whether or not the hole is to travel on at least one of the projections.

9. The image reading device according to claim 4, further comprising

a notification section configured to externally notify that the settings have been changed such that image reading is performed on one of the sides of the sheet of the original document upon the setting changing section changing the settings such that image reading is performed on one of the sides of the sheet of the original document.

10. The image reading device according to claim 5, further comprising

a notification section configured to externally notify that the settings have been changed such that image reading is performed on the sheets of the original document on a sheet-by-sheet basis upon the setting changing section changing the settings such that image reading is performed on the sheets of the original document on a sheet-by-sheet basis.

11. An image forming apparatus comprising:

an image forming section configured to form an image on a recording medium; and

the image reading device according to claim 1.
