Abstract
A document reader includes a reading unit that reads an image of a document medium, a second driving roller pair that nips and transports the document medium downstream of a read-enabling position of the reading unit, and a control unit that controls rotation of the second driving roller pair. The control unit stops the rotation of the second driving roller pair in a state in which the document medium is not positioned in the read-enabling position and in a state in which the document medium is nipped by the second driving roller pair.
Claims8
A document reader reading an image of a document medium being transported and outputting image data, the document reader comprising:
- a reading unit configured to read the image of the document medium;
- a first roller pair configured to nip and transport the document medium downstream of a read-enabling position of the reading unit on a transport path along which the document medium is transported;
- and
- a control unit configured to control a rotation of the first roller pair, wherein
- the control unit stops, as a document medium holding operation, the rotation of the first roller pair in a state in which the document medium is not positioned in the read-enabling position of the reading unit and in a state in which the document medium is nipped by the first roller pair.
A control method of a document reader including a reading unit configured to read an image of a document medium being transported, a printing function unit configured to print an image onto a print medium being transported, and a first roller pair configured to nip and transport the document medium downstream of the reading unit on a transport path along which the document medium is transported,
- the control method comprising;
- performing a document medium holding operation that stops rotation of the first roller pair in a state in which the document medium is not positioned in a read-enabling position of the reading portion and in a state in which the document medium is nipped by the first roller pair;
- and
- starting, after performing the document medium holding operation, printing onto the print medium by the printing function unit, when determination is made that the document medium is removed.
