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.

Description

technical field [0001] The present invention relates to a sheet conveying device and an image forming apparatus including the sheet conveying device. Background technique [0002] Demands for power saving of image forming apparatuses have increased in recent years. Therefore, there have been proposed image forming apparatuses equipped with a power saving mode in which power supply is limited compared to the normal mode. [0003] In an image forming apparatus equipped with a power saving mode, generally, the image forming apparatus shifts from the normal mode to the power saving mode when a predetermined threshold time elapses without being used. After shifting to the power saving mode, the power supply to each part (job execution part) of the image forming apparatus that executes a job is cut off, thereby reducing power consumption. [0004] In the structure of judging whether to shift to the power saving mode based on the non-use time of the image forming apparatus, if th...
