A sheet conveying device such as a feed mechanism includes a pick-up roller and a cover member. The pick-up roller feeds, into an apparatus, a sheet such as a document on a placing table such as a document placing table on which the sheet is placed. The cover member such as a pick-up cover covers the pick-up roller. The cover member is supported at both ends thereof on a shaft of the pick-up roller or on shaft bearings that receive the shaft of the pick-up roller.

Sheet conveying device, image reading device, and image forming apparatus

A document conveying device includes a document table on which a stack of document sheets is placed; a rotating shaft member detachably provided on a main body of the document conveying device; a feeding member configured to contact and feed a topmost sheet of the stack of document sheets, the feeding member being attached to the rotating shaft member via a driving force transmitting member; a separating unit configured to separate the topmost sheet from one or more sheets that are fed together with the topmost sheet, rotating members rotatably attached to the rotating shaft member; a holding member configured to hold the feeding member and the driving force transmitting member; and a rotating member position restricting unit configured to restrict a position of the rotating members other than the holding member to a given predetermined position with reference to a position of the holding member.

Document conveying device, image reading device, and image forming apparatus

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.
