Abstract
An image reading apparatus includes a transport section that can transport original documents along a transport path, a reading section configured to read images of the original documents transported by the transport section, an output controller configured to output data of the original documents read by the reading section, a multi-sheet feed detection sensor configured to detect a multi-sheet feed of the original documents transported by the transport section, and an instruction section configured to issue an instruction to disable multi-sheet feed detection by the multi-sheet feed detection section.
Claims20
An image reading apparatus comprising:
- a transport section including a roller configured to transport original documents along a transport path;
- a reading section including a sensor configured to read images of the original documents transported by the transport section;
- an output controller configured to output data of the original documents read by the reading section;
- a multi-sheet feed detection sensor configured to detect a multi-sheet feed of the original documents transported by the transport section;
- an instruction section including a switch configured to issue an instruction to disable multi-sheet feed detection by the multi-sheet feed detection sensor;
- and
- a transport detection sensor configured to detect the original documents transported by the transport section,
- wherein, after a job for sequentially transporting a plurality of original documents to perform a reading operation to read images is interrupted by multi-sheet feed detection performed by the multi-sheet feed detection sensor, the output controller determines whether a disabling mode in which the multi-sheet detection is disabled in accordance with an instruction from the instruction section has been set or not,
- when the disabling mode has not been set, the output controller stands by until the disabling mode is set, and when the job is restarted with the disabling mode having been set, the output controller merges first data that is read in the reading operation before the interruption and second data that is read in the reading operation after the restart into a single file and outputs the file,
- the disabling mode includes an original document unit disabling mode for disabling the multi-sheet feed detection by the multi-sheet feed detection sensor until the trailing edges of the original documents pass through the multi-sheet feed detection sensor, and
- if the original document unit disabling mode is instructed by the instruction section, in response to detection of the passage of the trailing edges of the original documents through the multi-sheet feed detection sensor based on a detection signal detected by the transport detection sensor, the multi-sheet feed detection performed by the multi-sheet feed detection sensor is enabled.

An image reading apparatus comprising:
- a transport section configured to transport original documents along a transport path;
- a reading section configured to read images of the original documents transported by the transport section;
- a multi-sheet feed detection section configured to detect a multi-sheet feed of the original documents transported by the transport section;
- an instruction section configured to issue an instruction to disable multi-sheet feed detection by the multi-sheet feed detection section based on an operation of the instruction section by a user;
- and
- a transport detection section configured to detect the original documents transported by the transport section,
- an output controller configured to output data of the original documents read by the reading section, the output controller determines whether a disabling mode in which the multi-sheet feed detection is disabled in accordance with the instruction from the instruction section has been set or not, after a job for sequentially transporting a plurality of original documents to perform a reading operation to read images is interrupted by multi-sheet feed detection performed by the multi-sheet feed detection section,
- the output controller outputs first data that is read in the reading operation before the interruption and second data that is read in the reading operation after the interruption such that the first data and the second data can be saved as a single file,
- wherein, the disabling mode includes an original document unit disabling mode for disabling the multi-sheet feed detection by the multi-sheet feed detection section until trailing edges of the original documents pass through the multi-sheet feed detection section, and
- if the original document unit disabling mode is instructed by the instruction section, the multi-sheet feed detection performed by the multi-sheet feed detection section is configured to change from being disabled to being enabled after detecting that the trailing edges of the original documents pass through the multi-sheet feed detection section based on a detection signal detected by the transport detection section.
