Abstract
If failure occurs in a part of reading units during a document reading operation, a user restarts an image reading apparatus to allow resuming the reading operation from the image of the document next to the image of the already read document. An image reading apparatus determines whether reading operation for reading the document can be resumed by using a first reading unit or a second reading unit if failure occurs in at least one of the first reading unit and the second reading unit during the reading operation, and causes a nonvolatile memory to store an image of a document already read by the reading operation and the image reading apparatus to restart if the reading operation can be resumed.
Claims18
An image reading apparatus comprising:
- a reading unit configured to execute a reading operation in which a first side of a document conveyed by an automatic document feeder is read by using a first reading unit and a second side of the document is read by using a second reading unit;
- a determining unit configured to determine whether the reading operation can be resumed by using the first reading unit or the second reading unit by restarting the image reading apparatus if failure occurs in at least one of the first reading unit and the second reading unit during the reading operation;
- and
- a control unit configured to cause a nonvolatile memory to store an image of the read document and the image reading apparatus to restart if reading operation can be resumed.
A control method for controlling an image reading apparatus, the control method comprising:
- executing a reading operation in which a first side of a document conveyed by an automatic document feeder is read by using a first reading unit and a second side of the document is read by using a second reading unit;
- determining whether the reading operation can be resumed by using the first reading unit or the second reading unit by restarting the image reading apparatus if failure occurs in at least one of the first reading unit and the second reading unit during the reading operation;
- selecting whether the image of the read document is stored in the nonvolatile memory and the image reading apparatus is restarted, or the image is not stored in the nonvolatile memory and the apparatus is restarted if it is determined that the reading operation can be resumed;
- and
- causing the image reading apparatus to restart according to a selection result.
A computer readable recording medium for storing a computer program for controlling an image reading apparatus, the computer readable recording medium comprising:
- a code to execute a reading operation in which a first side of a document conveyed by an automatic document feeder is read by using a first reading unit and a second side of the document is read by using a second reading unit;
- a code to determine whether the reading operation can be resumed by using the first reading unit or the second reading unit by restarting the image reading apparatus if failure occurs in at least one of the first reading unit and the second reading unit during the reading operation;
- a code to select whether the image of the read document is stored in the nonvolatile memory and the image reading apparatus is restarted, or the image is not stored in the nonvolatile memory and the image reading apparatus is restarted if the reading operation can be resumed;
- and
- a code to cause the image reading apparatus to restart according to a selection result.
