SHEET PROCESSING DEVICE AND IMAGE FORMING DEVICE PROVIDED WITH THE SAME

摘要

A sheet processing device includes: an adhesive-binding unit that applies an adhesive onto sheets stored in a stacker section one by one and adhesive-binds the sheets; a staple-binding unit that staple-binds sheets accumulated in the stacker section by means of staples; and a folding mechanism section having a folding roller that folds the adhesive-bound or staple-bound sheet bundle in two at a binding position of the adhesive-binding unit or staple-binding unit and a folding blade that pushes the bound sheet bundle into the folding roller. A folding speed of the folding mechanism section for the sheet bundle bound by the adhesive-binding unit is lower than a folding speed for the sheet bundle bound by the staple-binding unit; thereby, productivity of the folding processing is improved and occurrence of the peeling-off or break during the folding processing is reduced.

主权项

1. A sheet processing device that binds sheets and then folds a resultant sheet bundle, comprising:
a stacker section that stores sheets conveyed along a conveying path; an adhesive-binding unit that applies an adhesive onto the sheets stored in the stacker section to adhesive-bind the sheets; a staple-binding unit that binds the sheets stored in the stacker section by means of staples; a folding mechanism section that includes a folding roller that folds a sheet bundle in two at a binding position of the sheet bundle by the adhesive-binding unit or a binding position thereof by the staple-binding unit and a folding blade that pushes the sheet bundle into the folding roller; and a controller that controls the folding mechanism section, wherein the controller controls a folding speed of the folding mechanism section such that a folding speed for the sheet bundle bound by the adhesive-binding unit is lower than a folding speed for the sheet bundle bound by the staple-binding unit.
