Abstract:
1. A sheet reversing controller comprising: a first conveying path to convey a plurality of sheets in a first direction with a specified gap; a reversing portion arranged at the downstream in the first direction of the first conveying path, the reversing portion comprising a reversing roller capable of normal and reverse rotations to take and reverse the sheets from the first conveying path and a pinch roller arranged opposing to the reversing roller; a second conveying path to take and convey the sheets fed in a second direction differing from the first direction of the first conveying path by the reversing portion; and a controller to control a tangential velocity of an outer surface of the reversing roller so that the reversing roller takes the sheets from the first conveying path at a tangential velocity that is the same as a conveying velocity of the first conveying path and supplies the sheets taken therein to the second conveying path at another tangential velocity, in the reverse rotation, that is higher than the conveying velocity of the first conveying path, such that a conveying gap between a first sheet and a second adjacent succeeding sheet that are conveyed on the second conveying path becomes equal to the specified gap when conveyed on the first conveying path regardless of lengths of the sheets, wherein the controller sets a protruding amount of the sheets protruding between the reversing portion and the second conveying path when the sheets are stopped for reversing the conveying direction of the sheets to a fixed length regardless of the lengths of the sheets.
