An object of the invention is to provide a banknote storing/feeding unit which is capable of effectively utilizing winding spaces of a drum and a reel, to increase the number of banknotes to be stored. The banknote storing/feeding unit includes the drum which winds and rewinds a banknote together with a tape, and the reel which winds and rewinds the tape on and from the drum. A guide body swinging according to winding and rewinding of the tape and the banknote on and from the drum is provided between the drum and the reel. The guide body has a guide passage that guides the tape and the banknote to be wound and rewound on the drum. The guide body swings centering on a supporting point located within a region parallel to a virtual line connecting a rotational center of the drum and a rotational center of the reel.

The present disclosure provides an apparatus to support a sheet and configured to stably detect a presence of the sheet with a simple arrangement, and an image forming apparatus including such apparatus. A sheet discharging apparatus includes an apparatus body, a discharge member provided in the apparatus body and configured to discharge a sheet, a movable tray movable with respect to the apparatus body and including a sheet supporting surface configured to support the sheet discharged by the discharge member, a movable member supported by the movable tray and configured to move by being pressed by the sheet supported on the sheet supporting surface, and a detecting portion provided in the apparatus body and configured to detect a presence of the sheet supported on the sheet supporting surface in response to a position of the movable member.

An image forming apparatus, including: a sheet cassette; an image former; a fixer; a discharge tray; a conveyor configured to convey a sheet along a conveyance passage; a return conveyor configured to convey the sheet from a branch position between the fixer and the discharge tray to a merge position between the sheet cassette and the image former along a return passage which is branched from the conveyance passage at the branch position, passes below the sheet cassette, and merges with the conveyance passage at the merge position; a switchback roller disposed between the branch position and the discharge tray in the conveyance passage and configured to convey the sheet to the discharge tray when it rotates forwardly and to the return passage when it rotates backwardly; and an intermediate conveyance roller disposed in the return passage at a height level intermediate between the fixer and the sheet cassette.

Provided is a control unit of a conveying apparatus, the conveying apparatus including: a conveying unit that conveys recording paper along a conveyance path; an imaging unit that images the recording paper; and a light emitting unit arranged on an opposite side of the imaging unit across the conveyance path, wherein the control unit detects conveyance information of the recording paper based on image information of the recording paper imaged by the imaging unit in a state in which light from the light emitting unit is transmitted through the recording paper. The control unit detects the conveyance information of the recording paper based on a plurality of images of the recording paper imaged at different timings by the imaging unit.

A sheet conveying apparatus, includes: a first roller; an opening-closing member that is movable between an open position and a close position; a second roller; an urging member; a restraint member switching between a restraint state in which a rotation shaft of the second roller is restrained and a release state in which the rotation shaft is released from the restraint, by being moved, wherein, during the movement of the opening-closing member from the open position to the close position, the restraint member keeps the rotation shaft in the restraint state; and a releasing member that is moved by driving force from the drive source when the opening-closing member is in the close position and the rotation shaft is in the restraint state, the releasing member switching the rotation shaft to the release state by moving the restraint member as being engaged with the restraint member.

A printing apparatus includes a first transport roller pair configured to transport a medium while nipping the medium at a first nip portion, a second transport roller pair disposed downstream of the first transport roller pair and configured to transport the medium while nipping the medium at a second nip portion, and a device disposed between the first transport roller pair and the second transport roller pair in a transport path for the medium, and configured to nip the medium at a third nip portion, wherein a nip force in the third nip portion is weaker than a nip force in the first nip portion, and in a state where the medium is nipped at the first nip portion, a leading end of the medium is aligned with the second nip portion, and then the nipping at the first nip portion is released.
