A paper sheet handling device that facilitates removal of paper sheets blocked on a conveying path. The device includes a safe casing internally provided with a paper sheet storage box; a processing unit capable of being pulled out from, or stowed in, a main device; a conveying section coupled to the processing unit, and that forms a conveying path; a handover section coupled to a top plate of the safe casing to hand over the sheets between the storage box and the conveying path; and a positioning section that positions for connecting the handover section and the conveying path together when the processing unit is being stowed in the main device.

A sorting device is mounted, in an image forming apparatus, in a sheet discharge space open at its front and sheet-discharge-direction downstream side, insertably or extractably at the downstream side. The sorting device includes a base portion, a tray portion, and a flexible member. The base portion is mounted, with the tray portion, in the base portion. The base portion has, in its upstream part in sheet discharge direction, a base inclined portion inclined upward downstream. With the base portion mounted in the bottom portion, the base inclined portion faces, across a predetermined gap, a bottom inclined surface inclined upward downstream in discharge direction. The tray portion is supported on the base portion to be reciprocatable in sheet width direction orthogonal to discharge direction. The flexible member is fitted to the base inclined portion and fills the gap between the base inclined portion and the bottom inclined surface.

A sorting device includes a base portion, a tray portion, and a tray driving portion. The tray driving portion includes a motor, a supporting shaft, an input member, an output member, a link mechanism, and an urging member. The input member includes a first boss portion movably supported on the supporting shaft, and is reciprocatable up and down along the supporting shaft. The output member has a second boss portion coupled with the first boss portion via a ratchet mechanism. The link mechanism converts a rotary motion of the output member to a linear motion of the tray portion. The ratchet mechanism operates such that, when a predetermined or heavier load is applied to the output member via the tray portion, the input member is pushed down against the urging force of the urging member and engagement between the first and second ratchet teeth is released.

A printer apparatus includes a printer main body having a platen roller and a print head to print on recording paper, a cutter unit configured to cut the recording paper, and a presenter unit connected to the cutter unit, wherein the recording paper on which the print head has printed enters the presenter unit through the cutter unit, and comes out from a discharge slot of the presenter unit, wherein the presenter unit includes a first roller and a second roller configured to convey the recording paper placed therebetween, and a flapper disposed along a transportation path of the recording paper between the cutter unit and both the first roller and the second roller, and configured to be flipped open to an outside of the presenter unit to expose the transportation path, wherein an angle at which the flapper is open is selectively set to one of a plurality of different angles.

A sheet post-processing apparatus includes a sheet introducing unit, a first sheet discharge unit, a second sheet discharge unit, a sheet processing unit, a sheet conveyance unit, and a control unit. The first and the second sheet discharge unit are configured to be able to discharge a sheet to an outside. The sheet conveyance unit includes a sheet conveyance path arranged between the first sheet discharge unit and the second sheet discharge unit. The control unit controls the sheet conveyance unit to convey the sheet along the sheet conveyance path toward the first sheet discharge unit to a predetermined position at which the sheet is not discharged from the first sheet discharge unit to the outside, then convey the sheet along the sheet conveyance path in an opposite direction toward the second sheet discharge unit, and discharge the sheet from the second sheet discharge unit.

A first sheet conveying path extends from a sheet supply portion toward a sheet discharge portion. A second sheet conveying path extends, from a diverging position in the first sheet conveying path, toward a switch-to-back portion. A third sheet conveying path is a conveying path for the sheet that is reversed by the switch-to-back portion. A first movable guiding portion is rotatable between a first posture in which the sheet that has reached the diverging position is guided toward the sheet discharge portion, and a second posture in which the sheet is guided into the second conveying path. A second movable guiding portion is rotatable between a third posture and a fourth posture, in the second sheet conveying path. In the third posture, the second sheet conveying path is formed in conjunction with the first movable guiding portion. In the fourth posture, the third sheet conveying path is formed.
