PAPER CREASING DEVICE, PAPER POST-PROCESSING DEVICE, IMAGE FORMING DEVICE, AND IMAGE FORMING SYSTEM

摘要

PROBLEM TO BE SOLVED: To perform a cleaning work for a creasing blade that forms a crease by an automatic operation, thereby improving user's running cost and productivity. SOLUTION: A creasing device includes: the creasing blade 30 that performs creasing processing prior to paper folding processing; a cleaning member 51 that cleans the creasing blade 30; a motor 57 which moves the cleaning member 51 at a cleaning position of the creasing blade 30; position detecting sensors 58 and 59 which are disposed at two places within a moving range of a driving mechanism and detect a position of the cleaning member by a moving mechanism; and a controller 71 which decides a driving direction of the motor 57 based on detection conditions of the cleaning members 51 by the position sensors 58 and 59 in two places, drives the cleaning member 51 by the motor 57 to move it until the position sensor 58 on a side where the cleaning member 51 is not detected detects the cleaning member 51.
