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 reversing roller pair is controlled such that, when an abnormality occurs during the conveying of a sheet, the sheet is conveyed in a forward direction by the reversing roller pair, and is controlled to continue conveying until a state where the final sheet among the sheets conveyed in the forward direction is detected by a first detection portion, and subsequently to stop in a state where the final sheet is nipped by the reversing roller pair.

A sheet feeding device includes a driving roller, a driven roller rotated by the rotation of the driving roller, a non-conductive feeding guide, a conductive frame, a conductive bearing and an urging member to urge the driven roller toward the driving roller. The feeding guide includes a supporting portion to displaceably support the rotation shaft in an urging direction. The frame includes a positioning portion to position the driven roller in the urging direction by contact with the rotation shaft in a state in which the driving roller is urged by the driven roller.

An image forming apparatus includes an apparatus body, an image forming device to form an image on a recording medium, a casing to accommodate the image forming device, a sheet discharging port through which the recording medium having the image is discharged from the casing, a sheet stacker to stack the recording medium output through the sheet discharging port and opening on one side of the apparatus body and surrounded by outer walls including an outer wall having the sheet discharging port, an air guide opening disposed within a sheet passing range in a width direction of the recording medium in a sheet conveying path through which the recording medium having the image passes from the image forming device to the sheet discharging port, and an air suction fan to discharge air passing through the air guide opening to an outside of the casing.

An objective of the present disclosure is to prevent paper sheets from being folded or damaged when the paper sheets are stacked. A paper sheet stacking mechanism (banknote stacking mechanism 50) includes stacking wheels 52, rotary rollers 54, a transport mechanism 70 configured to insert a paper sheet between vanes 52b of the stacking wheels, and a guide (center guide 55) having a guide surface 551 configured to guide the paper sheet. The guide surface has a curved shape having a diameter about a rotary shaft, and the diameter gradually increases from an upstream side toward a downstream side in a rotation direction of the stacking wheels.

A paper sheet conveyance device for generating an airstream in a conveyance duct and for conveying a paper sheet inserted into the conveyance duct by being pushed from behind by a conveyance subsidiary body moving in the conveyance duct by receiving the airstream. The paper sheet conveyance device includes an air volume adjustment unit that adjusts a strength of the airstream according to a position of the conveyance subsidiary body moving in the conveyance path.
