A sheet handling apparatus for transporting a sheet along a transport path, the sheet handling apparatus comprising: a sheet transport mechanism which includes a pair of upper and lower endless belts (12, 13), wherein the sheet is transported one by one along the transport path in a state of being gripped between the endless belts (12, 13), and a plurality of kinds of sheet shifting mechanisms (20, 30) disposed along an extending direction of the transport path, and configured to shift a transported sheet in a width direction of the transport path, wherein the plurality of kinds of sheet shifting mechanisms (20, 30) include a first sheet shifting mechanism disposed in a sheet transporting direction, and a second sheet shifting mechanism disposed downstream of the first sheet shifting mechanism, and each of the first sheet shifting mechanism and the second sheet shifting mechanism has a different mechanism to shift the sheet in the width direction, characterized in that the first sheet shifting mechanism is configured to shift, in the width direction, the sheet which is transported in the state of being gripped between the paired upper and lower endless belts (12, 13) wherein the first sheet shifting mechanism includes skew rollers (22, 24) that are skewed relative to the extending direction of the transport path, wherein when the sheet that is transported in the state of being gripped between the paired upper and lower endless belts (12, 13) contacts with the skew rollers (22, 24), the sheet is shifted in the width direction, wherein in the plurality of skew rollers (22, 24), a direction in which each first skew roller is skewed relative to the extending direction of the transport path and a direction in which each second skew roller is skewed relative thereto, are different from each other, wherein a pair of left and right first skew rollers are disposed so as to be aligned along the width direction, and the pair of left and right second skew rollers are disposed so as to be aligned along the width direction, wherein the second skew rollers are disposed downstream of the first skew rollers in the sheet transporting direction in the transport path, wherein the first skew rollers are rotated in synchronization with each other by a first driving motor and the second skew rollers are rotated in synchronization with each other by a second driving motor, and wherein each first skew roller and each second skew roller are movable in the extending direction independently of the skew rollers oriented in the other directions. a sheet transport mechanism which includes a pair of upper and lower endless belts (12, 13), wherein the sheet is transported one by one along the transport path in a state of being gripped between the endless belts (12, 13), and a plurality of kinds of sheet shifting mechanisms (20, 30) disposed along an extending direction of the transport path, and configured to shift a transported sheet in a width direction of the transport path, wherein the plurality of kinds of sheet shifting mechanisms (20, 30) include a first sheet shifting mechanism disposed in a sheet transporting direction, and a second sheet shifting mechanism disposed downstream of the first sheet shifting mechanism, and each of the first sheet shifting mechanism and the second sheet shifting mechanism has a different mechanism to shift

direction in which each second skew roller is skewed relative thereto, are different from each other, wherein a pair of left and right first skew rollers are disposed so as to be aligned along the width direction, and the pair of left and right second skew rollers are disposed so as to be aligned along the width direction, wherein the second skew rollers are disposed downstream of the first skew rollers in the sheet transporting direction in the transport path, wherein the first skew rollers are rotated in synchronization with each other by a first driving motor and the second skew rollers are rotated in synchronization with each other by a second driving motor, and wherein each first skew roller and each second skew roller are movable in the extending direction independently of the skew rollers oriented in the other directions.
