摘要： PROBLEM TO BE SOLVED: To provide a sheet processing device which maintains a high productivity, can suppress the slippage of the sheet processing device position in the direction orthogonal to the sheet conveying direction at the minimum limit, and can carry out a high quality of process. SOLUTION: When a punching operation is selected, a sheet end part detecting sensor 93 is moved to a specific position (a sheet end part detection waiting position) fitting to the size of the sheet (S5). When the front end of the sheet is detected by a sheet detecting sensor 31, a punch slide drive start waiting time is calculated from the sheet conveying length (S7). When the time reaches to the punch slide drive start waiting time, a punch slide motor is driven, and the sheet end part detecting sensor 93 starts to move to a holing part 90 and the sheet width direction of the sheet end part detecting sensor 93, in order to detect the end part of the sheet (S10). When the sheet end part is detected by the sheet end part detecting sensor 93, the punch slide motor is stopped, and the movement of the holing part 90 and the sheet end part detecting sensor 93 is stopped (S30).

摘要： PROBLEM TO BE SOLVED: To provide an image forming system which can precisely associate the opening and closing state of a cover of an inserter with the operation, and improve the operability related to the operation including the insert mode by the association. SOLUTION: When an insert mode is set (S1003), it is determined whether an inserter cover is opened or not according to an output signal of a detecting sensor (S1004). Since the inserter mode is set when the inserter cover is opened, the effect (message, LED and the like) to that the inserter cover is opened is displayed (S1005).

摘要： PROBLEM TO BE SOLVED: To provide an image forming device capable of enhancing the operating easiness when transcribing material and special sheets of paper are put together and bound into a book without impairing the grade of printing workmanship on each special sheet of paper and the durability in transporting the transcribing material. SOLUTION: A special sheet of paper from an inserter 900 is inserted into sheets on which images are formed, and these sheets with special one(s) inserted are folded into two and bound into a book in such an arrangement that it is possible to spread and turn over page by page. When this book-making process is to be executed, composition of images to be formed on the sheets and rearrangement are performed so that the sheets to be bound lie in the correct sequence of pages. Insertion of the special sheet(s) into the ordinary is made so that the direction of the images formed on the sheets is identical to the direction of the image(s) on the special sheet using a finisher 500, and a post- processing (folding into two, binding, etc.) is applied to the sheets in the condition that special sheet(s) are inserted.

摘要： PROBLEM TO BE SOLVED: To prevent a needle from being caught into a groove part of an anvil after binding to cause a sheet conveying failure. SOLUTION: A sheet handling device for binding a plurality of sheets by a binding means and folding the sheets in two to discharge them, has a sheet conveying means having a rotatory-driving driving roller 68 and a pickup roller 69 displaceable between a pressing position of being drivenly rotated while pressing the sheet to a driving rotor, and a spaced position spaced from the driving roller 68; and a binding means having a forming part and an anvil 61d opposed to the forming part with a sheet path placed in between. After driving the forming part to the sheets to bind the sheet, the pickup roller 69 is displaced into the pressing position so that a binding needle 61f slips out of a groove part 61d2 of the anvil 61d.

摘要： PROBLEM TO BE SOLVED: To improve processing efficiency, and while to maintain the quality of a book-bound sheet bundle by providing a switch-back control means for controlling the sheet feeding speed and the sheet drawing speed in relation to a sheet folding means, which folds sheets discharged from an image forming device, so as to be different from each other. SOLUTION: A folding motor is fully turned on, and after a projecting plate 25a is drawn from a projecting plate home position sensor 82a, when the projecting plate 25a is projected so as to achieve a plate tip detecting sensor 82b, a folding clutch 74a is turned off till a discharge sensor 29 is turned on. When the discharge sensor 29 is turned on, movement of the folding motor in the normal rotating direction is stopped, and a folding timer is set, and this folding timer is reset after the set time is passed, and the folding motor is turned on at 50% of duty in the reverse rotating direction for example. Sheet or sheet bundle drawing speed in relation to folding rollers 26, 27 is controlled so as to be smaller than the feeding speed.
