POST-PROCESSING DEVICE AND IMAGE FORMATION APPARATUS

Japanese Patent JP2014177344

A

PROBLEM TO BE SOLVED: To provide a post-processing device configured to prevent a following form from getting jammed by continuing a post-processing operation on condition that the post-processing operation can be performed when a driving source used for the post-processing operation is returned to its home position owing to some abrupt factor.SOLUTION: There is provided a post-processing device which performs a binding process on a plurality of stacked forms by pressing and deforming a part of the form bundle into an uneven shape using a reversible driving source. The post-processing device includes a timer which detects the time of the binding process time by reverse driving of the driving source, and a control part which has an operation part for inputting at least the number and thickness of bound forms connected to its input side and also has the driving source and a shift movement driving part for the forms connected to its output side. The control part reverses the driving source when abnormality of the driving source is detected during the binding process, and normally rotates the driving source again to retry the binding process when the reversing process is completed normally.
