Abstract:
According to one embodiment, a sheet processing apparatus includes a reinforce roller to further reinforce the fold of a sheet which has been folded by a fold roller pair, a support portion to move the reinforce roller in a direction perpendicular to a sheet conveying direction, a sensor to sense a position of the support portion, a distance sensing portion to sense a distance to a first position and a distance to a second position from a stop position of the support portion, when the sensor senses an abnormal stop of the support portion, and a control unit to compare the distance to the first position and the distance to the second position sensed by the distance sensing portion and to control the support portion to move in a direction where a moving distance is shorter.
Abstract:
According to one embodiment, an image forming apparatus including an image visualizing section configured to visualize image data with a visualizing agent to obtain a visible image, an image moving section configured to move the visible image obtained by the image visualizing section to a sheet medium, a productivity setting section configured to set a number of times the image moving section moves the visible image to the sheet medium per unit time, and a sheet medium supplying section configured to supply the sheet medium from a sheet medium storing section to the image moving section at predetermined timing conforming to the number of times of the movement of the visible image set by the productivity setting section.
Abstract:
An image erasing apparatus includes: a supply unit which supplies a recording medium; a collection unit which collects the recording medium supplied by the supply unit; plural carrying roller pairs which carry the recording medium supplied by the supply unit, toward the collection unit; a detection unit which acquires information about a metallic foreign matter adhering to the recording medium; a heating unit which heats the recording medium to a color erasing temperature of a developer or higher; and a carrying control unit which decelerates a rotation speed of the plural carrying roller pairs from a first speed to a second speed when the information about the metallic foreign matter is acquired by the detection unit.
Abstract:
A sheet finisher of the invention includes a saddle stitch unit configured to stitch a center of a sheet bundle in which printed sheets are bundled, a fold unit configured to fold the center stitched by the saddle stitch unit and to form a fold line, and a fold reinforcing unit configured to reinforce the fold line formed by the fold unit, the fold reinforcing unit includes a placement table on which the sheet bundle transported from the fold unit is placed, and a roller unit that includes a reinforce roller and moves the reinforce roller along a direction of the fold line while pressing it to the fold line, and the placement table is provided with a groove-like edge clearance along an edge of the sheet bundle.
Abstract:
There is provided a device detecting curling of a sheet, the device including a first guide member carrying the sheet; a second guide member including a carriage path that is broader than the carriage path of the first guide member and accepting the curling of the sheet; and sensors with detection ranges into which a portion of the curling of the sheet enters, in the carriage path of the second guide member.
Abstract:
There is provided a decoloring device including a decoloring unit, a first sheet conveying unit, a first sheet feed unit, a thickness detecting unit, a decolorability determining unit, and a second sheet feed unit. The first sheet conveying unit conveys the sheet to the decoloring unit. The first sheet feed unit feeds the sheet to the first sheet conveying unit. The decolorability determining unit determines whether or not the sheet which is subject to thickness detecting is decolorable by the decoloring unit based on a detection result in the thickness detecting unit. A second sheet feed unit is disposed at a downstream side in relation to the thickness detecting unit and at an upstream side in relation to the decoloring unit in a sheet conveying path by the first sheet conveying unit and feeds the sheet to the first sheet conveying unit.
Abstract:
A sheet stack apparatus comprises a storage portion configured to support sheets conveyed one by one in a standing position, a receiving portion configured to receive lower ends of the sheets supported by the storage portion, an assisting member configured to move from a first position to the storage portion side and at a second position where the assisting member contacts with the sheets conveyed to the storage portion, assist stacking of the sheets on the storage portion, and a holding member configured to move in correspondence with a movement of the assisting member via an attaching portion, when the assisting member is at the second position, separate from the lower ends of the sheets, and when the assisting member is at the first position where the assisting member is separated from the sheets supported by the storage portion, contact with the lower ends of the sheets, thereby hold them on the storage portion side.
Abstract:
A sheet folding apparatus includes a sheet supporting member which has an inclined surface to support a stack of sheets, a sheet position adjuster which adjusts a position of the stack of sheets along the inclined surface, a sheet pressing unit which presses the stack of sheets from a lower side of the stack of sheets to an upper side of the stack of sheet, and a folding unit which folds the stack of sheets pressed by the sheet pressing unit.
Abstract:
According to one embodiment, a decolorizing device includes a first stacker to stack sheets to be decolorized images on the sheets, a second stacker arranged adjacent to the first stacker, wherein the sheets stacked on the first stacker is kept waiting on the second stacker in order to be decolorized the images, a pressing unit to urge the sheets stacked on the second stacker downward and keep the sheets stacked on the second stacker flat, an image decolorizing unit to decolorize the images on the sheets, and a sheet feed unit positioned on an upper surface of the pressing unit to convey the sheets pressed on the pressing unit from the second stacker to the image decolorizing unit.
Abstract:
The present invention provides an image decoloring apparatus including a plurality of, at least three, sheet load portions, each of the portions being able to be loaded with a sheet, an decoloring portion which performs decoloring an image on a sheet formed with the decolorable colorant, a first sheet transfer portion which transfers the sheet loaded in each of the plurality of sheet load portions to the decoloring portion, and a second sheet transfer portion which transfers the sheet after the decoloring is performed thereto by the decoloring portion to each of the plurality of sheet load portions.
