Abstract
An image reading apparatus includes a stacking unit on which a document to be fed is stacked, a sensor configured to output a signal indicating that the document has been stacked on the stacking unit, a discharging unit to which the document is to be discharged, wherein the discharging unit includes a lamp, and a control unit configured to turn on the lamp in response to the signal indicating that the document has been stacked on the stacking unit output from the sensor.
Claims22
An image reading apparatus comprising:
- a stacking unit on which a document to be fed is stacked;
- a sensor configured to output a signal indicating that the document has been stacked on the stacking unit;
- a feeding unit configured to feed the document stacked on the stacking unit;
- an image reading unit configured to read the document fed by the feeding unit;
- a discharging unit onto which a document which has been read by the image reading unit is discharged;
- an illuminating unit configured to illuminate the discharging unit;
- and
- a control unit configured to turn on the illuminating unit in response to the signal, output by the sensor, indicating that the document has been stacked on the stacking unit before the feeding unit feeds the document.

An image reading apparatus comprising:
- a stacking unit on which a document to be fed is stacked;
- a first sensor configured to output a signal indicating that the document has been stacked on the stacking unit;
- a feeding unit configured to feed the document stacked on the stacking unit;
- an image reading unit configured to read the document fed by the feeding unit;
- a discharging unit onto which a document which has been read by the image reading unit is discharged;
- a second sensor configured to output a signal indicating that the document has been discharged on the discharging unit;
- an illuminating unit configured to illuminate the discharging unit;
- and
- a control unit configured to turn on the illuminating unit if the second sensor outputs the signal indicating that the document has been discharged on the discharging unit and the first sensor outputs the signal indicating that the document has been stacked on the stacking unit, and not to turn on the illuminating unit if the second sensor does not output the signal indicating that the document has been discharged on the discharging unit and the first sensor outputs the signal indicating that the document has been stacked on the stacking unit, and to turn on the illuminating unit according to a feed start signal.
