A sheet passage changing apparatus includes a plurality of swingable changing devices for changing a sheet transporting direction; common drivers for swinging the plurality of changing devices; a controller for actuating the drivers, before a sheet reaches an upstream one of the changing devices, to actuate the upstream one of the changing devices, thus changing the sheet transporting direction and for actuating the drivers, after the sheet passing through the upstream changing device and before the sheet reaches a downstream one of the changing device, to actuate the downstream changing device, thus changing the sheet transporting direction.
