Abstract
A sheet feeding device includes: a sheet housing unit that is mounted on a body of an apparatus such that the sheet housing unit can be pulled out of the body of the apparatus; a blowing unit that blows air toward a sheet housed in the sheet housing unit; a heating unit that heats the air blown by the blowing unit; and a control unit that controls the blowing unit and the heating unit. In the sheet feeding device, the control unit is configured to drive the blowing unit and the heating unit during a sheet feeding operation of feeding the sheet from the sheet housing unit, and continuously drive the blowing unit and stop the heating unit when the sheet housing unit is pulled out of the body of the apparatus during the sheet feeding operation.
Claims8
A sheet feeding device, comprising:
- a sheet housing unit that is mounted on a body of an apparatus such that the sheet housing unit can be pulled out of the body of the apparatus;
- a blowing unit that blows air toward a sheet housed in the sheet housing unit;
- a heating unit that heats the air blown by the blowing unit;
- and
- a control unit that controls the blowing unit and the heating unit, wherein
- the control unit is configured to:
- drive the blowing unit and the heating unit during a sheet feeding operation of feeding the sheet from the sheet housing unit;
- continuously drive the blowing unit and stop the heating unit when the sheet housing unit is pulled out of the body of the apparatus during the sheet feeding operation;
- and
- reduce an airflow rate of the blowing unit from a reference airflow rate to an airflow rate lower than the reference airflow rate when the sheet housing unit is pulled out of the body of the apparatus during the sheet feeding operation.

- and
- change, in accordance with a drive time of the heating unit until the sheet housing unit is pulled out of the body of the apparatus, an airflow rate of the blowing unit after the heating unit is stopped.
An image forming apparatus, comprising:
- a sheet feeding device comprising:
- a sheet housing unit that is mounted on a body of the image forming apparatus such that the sheet housing unit can be pulled out of the body of the image forming apparatus;
- a blowing unit that blows air toward a sheet housed in the sheet housing unit;
- a heating unit that heats the air blown by the blowing unit;
- and
- a control unit that controls the blowing unit and the heating unit;
- and
- an image forming unit that forms an image on the sheet fed by the sheet feeding device, wherein
- the control unit is configured to:
- drive the blowing unit and the heating unit during a sheet feeding operation of feeding the sheet from the sheet housing unit;
- continuously drive the blowing unit and stop the heating unit when the sheet housing unit is pulled out of the body of the apparatus during the sheet feeding operation;
- and
- reduce an airflow rate of the blowing unit from a reference airflow rate to an airflow rate lower than the reference airflow rate when the sheet housing unit is pulled out of the body of the apparatus during the sheet feeding operation.
