<p>PROBLEM TO BE SOLVED: To provide a sheet processor including a configuration capable of preventing reduction of productivity by preventing a change of a conveyance form of a sheet continuously introduced to a folding position.SOLUTION: Control of a first pattern in which first guide means G1 disposed near a second conveyance roller pair 2 positioned on an introduction side when a sheet P1 to be introduced has reached a creasing position from an introduction position is changed over to a first position (G1-1) in which flexure P2W is generated in a part of the sheet by making a conveyance path length of the sheet longer than a conveyance path length in normal time, and a second pattern in which the first guide means G1 is changed over to a second position (G1-2) in which interference in the creasing position of the preceding sheet P1 is prevented by making the same action as provision of a conveyance interval L1 with the preceding sheet P1 be able to be obtained by bending a part of the sheet without changing a conveyance speed of the second conveyance roller pair 2 is executed.</p> |
