Abstract

A sheet conveying device includes: a sheet housing unit that houses a sheet; a sheet conveying unit that conveys the sheet; a sheet detection unit that detects presence or absence of the sheet in the sheet housing unit; a sheet nipping unit that nips the sheet housed in the sheet housing unit; and a control unit. The control unit controls the sheet nipping unit to reach a nipping state to nip the sheet in the sheet housing unit upon the sheet detection unit detecting a sheet-present state, executes a power saving mode to stop supplying power to at least a part of the electric mechanisms when no drive command is input for a predetermined time, and controls the sheet nipping unit to cancel the nipping state before execution of the power saving mode.
