Abstract
A sheet carrying apparatus comprises a job executing portion that includes a sheet carrying portion for carrying a sheet, a power supply portion that performs usual power supply to the job executing portion in a usual mode and stops the power supply to the job executing portion in a power saving mode that restricts the power supply more than the usual mode; an ejecting portion into which the sheet carried by the sheet carrying portion is ejected, and an ejected sheet detecting portion that detects presence of the sheet ejected in the ejecting portion, and when there is no sheet in the ejecting portion after a job including ejecting of the sheet into the ejecting portion ends, the power supply portion shifts from the usual mode to the power saving mode.
Claims4
A sheet carrying apparatus comprising:
- a job executing portion that includes a sheet carrying portion for carrying a sheet;
- a power supply portion that performs usual power supply to the job executing portion in a usual mode and stops the power supply to the job executing portion in a power saving mode that restricts the power supply more than the usual mode;
- an ejecting portion into which the sheet carried by the sheet carrying portion is ejected;
- an ejected sheet detecting portion that detects presence of the sheet ejected in the ejecting portion;
- and
- an imparting portion;
- wherein
- when a not-used period during which the apparatus is not used exceeds a predetermined threshold period, the power supply portion is configured to shift from the usual mode to the power saving mode;
- when the ejected sheet detecting portion detects that there is no sheet in the ejecting portion before a predetermined period elapses after the job including the ejecting of the sheet into the ejecting portion ends, the power supply portion shifts from the usual mode to the power saving mode irrespective of whether the not-used period exceeds the threshold period or not;
- and
- after the job including the ejecting of the sheet into the ejecting portion ends, when the predetermined period elapses with presence of the sheet in the ejecting portion detected by the ejected sheet detecting portion, the power supply portion does not shift from the usual mode to the power saving mode, and the imparting portion imparts that there is the sheet left in the ejecting portion, thereafter, when the ejected sheet detecting portion detects that there is no sheet in the ejecting portion, the power supply portion shifts from the usual mode to the power saving mode.
