## 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.

## Claims

### Claim 1

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; and
an ejected sheet detecting portion that detects presence of the sheet ejected in the ejecting portion; wherein
when the ejected sheet detecting portion detects that 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.

### Claim 2 (depends on 1)

The sheet carrying apparatus according to claim 1, wherein
when a not-used period during which the apparatus is not used exceeds a predetermined threshold period, the power supply portion shifts from the usual mode to the power saving mode; and
when the ejected sheet detecting portion detects that there is no sheet in the ejecting portion 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.

### Claim 3 (depends on 1)

The sheet carrying apparatus according to claim 1, comprising
an imparting portion which imparts that the sheet remains in the ejecting portion when a predetermined period during which the ejected sheet detecting portion detects that there is the sheet in the ejecting portion elapses after the job including the ejecting of the sheet into the ejecting portion ends.

### Claim 4 (depends on 3)

The sheet carrying apparatus according to claim 3, wherein
the imparting portion includes a warning sound generating circuit and imparts that the sheet remains in the ejecting portion by generating a warning sound from the warning sound generating circuit.

### Claim 5 (depends on 3)

The sheet carrying apparatus according to claim 3, wherein
the imparting portion includes a light emitter and imparts that the sheet remains in the ejecting portion by turning on and off the light emitter.

### Claim 6 (depends on 1)

An image forming apparatus comprising the sheet carrying apparatus according to claim 1.
