In the control of a cutting mechanism of a sheet processing apparatus, when rear end cut region of a sheet is finely cut and divided into predetermined fine-cutting unit length, if sheet conveying direction length of rearmost end divided region is equal to or more than minimum reference length corresponding to the distance between cutting position of the cutting mechanism and nipping position of a pair of first conveying rollers and is less than maximum reference length in which predetermined fine-cutting unit length is added to minimum reference length, upper and lower blades of the cutting mechanism are held opened immediately after the downstream edge of rearmost end divided region is cut and the pair of first conveying rollers are driven at limited conveying speed lower than normal conveying speed.

Method for controlling sheet processing apparatus

In a processing machine including a processor having a processing blade and a receiver having a reception member and in which a blade edge of the processing blade and a reception portion, of the reception member, engage with each other to process a paper sheet therebetween, the processing blade is one processing blade selected from a blade group and is attached to the processor so as to be changeable to another processing blade of the blade group, reception portions of kinds corresponding to a plurality of kinds of the processing blades of the blade group are formed on the reception member, and the processing blade attached to the processor is positioned so as to be in a position where the blade edge is engageable with the reception portion of the corresponding kind.

Processing machine and paper sheet processing device

A paper processing apparatus equipped with a paper transferor for sequentially transferring paper sheets while maintaining a predetermined interval between a certain paper sheet and the next paper sheet; a paper position detector for detecting the position of a paper sheet; a plurality of processors for performing processing for the paper sheet; an information reader for reading information relating to processing to be performed for the paper sheet; and a controller for controlling operations relating to the paper transferor, the paper position detector, the plurality of processors, and the information reader, wherein upon judging that the certain paper sheet has passed through a certain processor, the controller carries out control to adjust the widthwise position of the certain processor so as to be adapted for the processing for the next paper sheet.

Paper processing apparatus

A stacker device includes a conveying belt, a longitudinal receiving guide, a paper sheet discharge detecting part, a first detecting part having a rod body, a second detecting part, and a control part for controlling the guide drive mechanism and the belt drive mechanism. The control part is formed so as to control both the mechanisms so that after the predetermined time T, which is required for the paper sheet to be stacked on the stacking surface after the paper sheet discharge detecting part detects the rear edge of the paper sheet having been conveyed to the discharging roller, passes and until the first detecting part detects the paper sheet, the longitudinal receiving guide and the conveying belt move to the upstream side of the conveyance direction at the same time, and after that, until the first detecting part does not detect the paper sheet, the longitudinal receiving guide and the conveying belt move to the downstream side of the conveyance direction at the same time. Additionally, the control part is formed so as to control the belt drive mechanism so that, when the second detecting part detects the non-standing position of the paper sheet, only the conveying belt moves to the downstream side of the conveyance direction by the predetermined distance.

Stacker device

When the sheet () is mounted onto the conveyance surface (), the alignment guide () is located at the retraction position by the alignment guide moving mechanism, and after the sheet () is mounted onto the conveyance surface (), the alignment guide () is located at the guide position by the alignment guide moving mechanism.

Cross conveying device

A paper folding mechanism includes: first and second folding rollers (); first and second conveyance rollers (); a protrusion member (); and a control part. Both the rollers () are provided so that a paper is sandwiched therebetween with its fold line located in front, and is allowed to pass therethrough in a first direction. The first folding roller () and the first conveyance roller () are provided so that the paper is sandwiched therebetween and conveyed in a second direction orthogonal to the first direction. The second folding roller () and the second conveyance roller () are provided so that the paper is sandwiched therebetween and conveyed in any one of the second direction and the direction opposite thereto. The protrusion member () is provided so that the fold line of the paper conveyed by both the rollers () is protruded in the first direction and fed between both the rollers ().

Paper folding mechanism and paper folding apparatus

A paper sheet conveying device is equipped with a conveying path () formed of conveying roller pairs and a controlling section conveying rollers. The conveying path () is composed of a first-half conveying path (A) and a last-half conveying path (B). The first-half conveying path (A) has a first-half driving mechanism for controlling the rotational speed of the lower conveying rollers and a first-half vertically moving mechanism for vertically moving the upper conveying rollers. The last-half conveying path (B) has a last-half driving mechanism for controlling the rotational speed of the lower conveying rollers and a last-half vertically moving mechanism for vertically moving the upper conveying rollers. The controlling section is configured so as to control the first-half driving mechanism, the first-half vertically moving mechanism, the last-half driving mechanism and the last-half vertically moving mechanism depending on the position of the paper sheet being conveyed.
