Abstract:
A sheet processing apparatus to perform stapling includes a sheet stacking portion receiving a sheet for a sheet bundle and a positioning member against which an end of the sheet is abutted to position the sheet bundle. The positioning member is movable to adjust a stapling position on the sheet bundle where a staple processing portion performs a stapling process. After the stapling process is performed, a fold processing portion folds the sheet bundle in two. One of two surfaces of the folded sheet bundle slides on a conveyance guide member while a conveyance guide member guides the folded sheet bundle. The stapling process is performed while the stapling position is previously moved, by a predetermined distance, to an opposite area side of the sheet bundle opposite to an area that becomes the one of two surfaces of the folded sheet bundle when the sheet bundle is folded in two.
Abstract:
The present invention relates to a sheet stacking device comprising a discharging portion, a moving portion that holds a downstream end portion of the sheet, a stacking portion and a control portion that controls the discharging portion and the moving portion. The control portion controls at least one of the discharging portion and a moving portion so that the movement velocity of the moving portion is higher than the sheet discharge velocity of the discharging portion, and separates the sheet from the moving portion by using a velocity difference between the movement velocity and the sheet discharge velocity.
Abstract:
A sheet processor includes a holding unit for holding a folded batch of sheets, a pressing member for pressing against a folded portion of the batch of sheets, a nipping member for nipping portions of the batch adjacent to the folded portion so as to nip the batch of sheets from opposite directions, and a casing for supporting the pressing member and the nipping member.
Abstract:
A sheet bundle spine folded portion flattening apparatus is provided with a conveying portion which conveys the folded sheet bundle with the spine folded portion of the folded sheet bundle at a head, a sheet bundle moving device for moving it in a direction along the spine folded portion of the sheet bundle, and a pressing device for pressing the spine folded portion of the sheet bundle being moved by the sheet bundle moving device, and is adapted to press and flatten the spine folded portion of the sheet bundle being moved by the sheet bundle moving device, by the pressing device and therefore, can flatten the spine folded portion almost without stopping the movement of the sheet bundle, as compared with the conventional art, and the sheet bundle treating efficiency is enhanced.
Abstract:
An inspection device having a reading portion for reading an image on a sheet having an image formed thereon, a storage portion for storing therein image data read by the reading portion, and a selecting portion for selecting one of a first mode for storing the image data read by the reading portion in the storage portion, and a second mode for judging whether the image data read by the reading portion is similar to the image data stored in the storage portion.
Abstract:
A folded back portion flattening device includes a gripper and a presser. The gripper grips a sheet bundle formed into a booklet with the folded back portion protruding from the gripper. The presser presses the folded back portion of the sheet bundle gripped by the gripper, and includes pressing rollers which have pressing rotational surfaces and which are disposed along the folded back portion. The pressing rotational surfaces press the folded back portion. The pressing rollers are disposed so that the rotational pressing surface of a second pressing roller, which presses the folded back portion after the rotational pressing surface of a first pressing roller has pressed the folded back portion, presses deeper into an edge of the sheet bundle than the rotational pressing surface of the first pressing roller. At least one of the gripper and presser is movable in a direction parallel to the folded back portion.
Abstract:
An adsorption standby unit is provided upstream in the sheet conveying direction of a sheet stacking portion, which stacks sheets to be processed thereon. During processing of sheets on the sheet stacking portion, the next sheet to be processed is adsorbed and put in a standby state by the adsorption standby unit, so that the sheet can be retained and put in a standby state without switching the sheet back.
Abstract:
A sheet processor includes a holding unit for holding a folded batch of sheets, a pressing member for pressing against a folded portion of the batch of sheets, a nipping member for nipping portions of the batch adjacent to the folded portion so as to nip the batch of sheets from opposite directions, and a casing for supporting the pressing member and the nipping member.
Abstract:
The proposed apparatus is designed for being capable of recovering even when the overlapped transport of insert sheets has occurred without stopping the apparatus, thereby providing an improved utility to the users. The apparatus includes a first sheet feeder for sequentially separating blank sheets into individual sheet, an image forming device for forming images on the blank sheets, a transport device for waiting the blank sheet to be supplied to the image forming apparatus at predetermined time, a second sheet feeder for sequentially separating the insert sheets into individual sheet, an overlapped transport detecting device for determining whether or not the insert sheets have been transported in overlapped condition, and a controller for discharging all the insert sheets of a set involved in the overlapped transport onto a predetermined place, finding the first insert sheet of a next set of insert sheets, and discontinuing the drive of the transport device.
Abstract:
An image forming apparatus has an abnormality detecting device for detecting the abnormality of the sheet, an abnormal sheet containing portion for containing therein the sheet of which the abnormality has been detected, a normal sheet containing portion for temporarily containing therein a normal sheet of which the abnormality has not been detected, and a controlling portion for controlling the image forming portion so that the abnormal sheet is contained in the abnormal sheet containing portion, and that an image formed on the abnormal sheet may be formed on a predetermined subsequent sheet subsequent to the abnormal sheet. The normal sheet between the abnormal sheet and the predetermined subsequent sheet is contained in the normal sheet containing portion after the abnormal sheet is contained in the abnormal sheet containing portion, and the normal sheet contained in the normal sheet containing portion is delivered after the predetermined subsequent sheet has been delivered.
