A SHEET PROCESSING APPARATUS

In the control of a cutting mechanism of a sheet processing apparatus, when rear end cut region (Sr) of a sheet is finely cut and divided into predetermined fine-cutting unit length (Lr0), if sheet conveying direction length (Lr1) of rearmost end divided region (Sr1) is equal to or more than minimum...

Summary:In the control of a cutting mechanism of a sheet processing apparatus, when rear end cut region (Sr) of a sheet is finely cut and divided into predetermined fine-cutting unit length (Lr0), if sheet conveying direction length (Lr1) of rearmost end divided region (Sr1) is equal to or more than minimum reference length (D1) corresponding to the distance between cutting position (P1) of the cutting mechanism (22) and nipping position (P2) of a pair of first conveying rollers (12) and is less than maximum reference length (D2) in which predetermined fine-cutting unit length (Lr0) is added to minimum reference length (D1), upper and lower blades (22A, 22B) of the cutting mechanism (22) are held opened immediately after the downstream edge of rearmost end divided region (Sr1) is cut and the pair of first conveying rollers (12) are driven at limited conveying speed (V2) lower than normal conveying speed (V1).
