摘要： A sheet conveying device includes a blocking member having a blocking surface with which a leading end of a sheet that is being conveyed comes into contact for obliquity correction. The blocking member is rotated by being pushed by the sheet against an urging force of a positioning unit that positions the blocking member to be in the standby position. The blocking member is rotatable to be in a sheet-passage-allowing orientation in which the sheet is allowed to pass. When a trailing end of the sheet that is being conveyed has passed the blocking member, the blocking member that is in the sheet-passage-allowing orientation rotates in a same direction as a sheet conveyance direction and is positioned to be in a standby position.

摘要： When a retard roller is rotating in a sheet feeding direction, the rotation is transmitted to a pickup roller and the pickup roller rotates in a direction for conveying the sheet. When the retard roller is rotating in a direction opposite to the sheet feeding direction or is stationary, the pickup roller does not feed the sheet. Therefore, in a successive feeding operation, the sheet to be fed next is always conveyed such that the leading end thereof reaches a nip position between a feed roller and the retard roller. Therefore, the intervals between the sheets are uniform in the successive feeding operation.

摘要： A printer includes a fixing device that fixes a toner image formed on a sheet and a sheet delivery roller pair for delivering the sheet on which the toner image is fixed by the fixing device onto a sheet delivery tray placed outside of a printer main body. The printer includes a supporting member that supports an upstream edge portion of the sheet in a delivery direction delivered from the sheet delivery roller pair so that the upstream edge portion does not fall down on the sheet delivery tray. The printer includes a blower unit that blows air along a lower surface of the sheet supported by the supporting member from the upstream edge portion of the sheet in the delivery direction toward a downstream edge portion of the sheet in the delivery direction.
