Disclosed are a paper discharging mechanism and printing device having the same. The paper discharging mechanism includes: a frame provided with a paper outlet thereon; a swinging rack, configured to be swingable relative to the frame; a conveying roller assembly provided on the swinging rack; a first drive assembly, which is in a transmission connection with the conveying roller assembly and configured to drive the same to deliver a paper to the paper outlet; a first detection assembly, configured to detect a position of the swinging rack relative to the frame; the swinging rack swings in a direction away from the paper outlet when the paper outlet is blocked.

Meandering of a medium at a time of transporting is reduced. A recording apparatus which transports medium, and performs recording on the medium, the apparatus includes a recording unit; a medium clamping unit which is provided on a side further upstream than the recording unit in a transport direction, and clamps the medium therebetween; and a medium support unit which is provided on the side further upstream than the medium clamping unit in the transport direction, and supports the medium, in which the medium is slackened between the medium clamping unit and the medium support unit.

A sheet folding apparatus includes: a conveying roller conveying a sheet in a predetermined conveying direction; a folding roller pair disposed downstream of the conveying roller in the conveying direction and rotating while nipping a predetermined position of the sheet to form a fold; a conveying path for conveying the sheet in the conveying direction from the conveying roller to the folding roller pair; an abutting member moving downstream in the conveying direction and abutting against the predetermined position of the sheet to bend the sheet downstream; and a loop space where the sheet is bent between the conveying roller and folding roller pair in a direction crossing the conveying direction. The folding roller pair stops while nipping a front end of the sheet fed from to form a loop of the sheet in the loop space, and the abutting member moves to abut against the loop.

The folding roller pair stops while nipping a front end of the sheet fed from to form a loop of the sheet in the loop space, and the abutting member moves to abut against the loop.

A printing apparatus includes a stacking portion on which a print medium printed by a printing unit configured to perform printing is stacked, a discharge unit configured to convey the print medium printed by the printing unit to the stacking portion, a passage forming portion arranged above the stacking portion so as to face the stacking portion and configured to form a discharge passage of the print medium together with the stacking portion, and an outlet port located in a downstream end of the discharge passage in a conveying direction of the print medium. In the outlet port, the passage forming portion extends to the downstream side of the stacking portion in the conveying direction.

A clamping device for a feed of a printable medium comprises a clamp to clamp the printable medium; and a force transfer mechanism to press the clamp against the printable medium; wherein the clamp comprises a magnet to increase a force onto the printable medium during clamping.

Meandering of a medium at a time of transporting is reduced. A recording apparatus which transports medium and performs recording on the medium is provided. The apparatus includes a recording unit, a medium clamping unit which is provided on a side further upstream than the recording unit in a transport direction, and clamps the medium therebetween, and a medium support unit which is provided on the side further upstream than the medium clamping unit in the transport direction, and supports the medium. The medium is slackened between the medium clamping unit and the medium support unit.

In a binding discharge process, a binding process is performed on a plurality of sheets positioned at a binding position by repeating a process in which, after a conveyed sheet is conveyed in a reverse direction on a placement portion by a second conveyance portion to cause a downstream end of the sheet to abut an abutment portion, the sheet is moved in a shift direction and positioned at the binding position by a first shifting portion, and the plurality of sheets subjected to the binding process are discharged onto the stacking portion by a discharge portion. In a switchbackless shift discharge process, the conveyed sheet is shifted in the shift direction by the first shifting portion by driving a driving portion without conveying the sheet in the reverse direction by the second conveyance portion, and is discharged onto the stacking portion by the discharge portion.

An automatic document feeding device having a main body, a stopping assembly, an actuating assembly and a controller. The main body has a sheet conveying channel of a curvature shape. A sheet feeding roller assembly and a sheet conveying roller assembly are arranged on the sheet conveying channel. The stopping assembly is arranged between the sheet feeding roller assembly and the sheet conveying roller assembly. The stopping assembly is capable of being located in or out of the sheet conveying channel. A buffering channel is located between the stopping assembly and the sheet feeding roller assembly. The controller is electrically connected with the actuating assembly and the sheet feeding roller assembly. The controller controls the actuating assembly to hold the stopping assembly in the sheet conveying channel to block the sheet conveying channel in a predetermined period, and then controls the actuating assembly to stop holding the stopping assembly.

A post-processing apparatus includes a processing tray for stacking a sheet and a detection sensor for detecting the presence or absence of the sheet placed on the processing tray. The post-processing apparatus includes a pinch roller for moving towards the processing tray if the detection sensor does not detect the sheet, and a longitudinal alignment roller configured to rotate by a predetermined amount while sandwiching the sheet in the processing tray with the pinch roller to elongate the sheet. By holding a rear end of the sheet in the processing tray with a paddle section and elongating the sheet towards the downstream side with the longitudinal alignment roller, the presence or absence of the sheet is detected by the detection sensor.
