According to one embodiment, a post-processing apparatus includes a first sensor, a second sensor, and a control unit. The first sensor detects an object in a predetermined area in which a predetermined post-process is performed on a sheet conveyed from an image forming apparatus. The second sensor detects an object at a position closer to an opening in the area than the position of the first sensor with respect to the opening through which the sheet passes when the post-processed sheet is discharged from the area. When the second sensor detects an object before the first sensor detects the object, the control unit performs a predetermined process for preventing the occurrence of a failure.

A decoloring unit decolors the image on a sheet using heating. A control unit controls, based on a number of sheets decolored by the decoloring unit in a processing job immediately prior to the current processing job, an intensity of the light emitted from the light emitting unit for performing a current processing job.

Image processing apparatus

An image processing apparatus includes a light emitting unit that emits light, a document reading unit, an image forming unit, a decoloring unit, and a control unit. The document reading unit generates image data from an original document that is irradiated with light from the light emitting unit. The image forming unit forms an image on a sheet based on the image data generated by the document reading unit, wherein the image is formed of a decolorable material that is decolored when heated to a predetermined temperature or higher. The decoloring unit decolors the image on the sheet using heating. The control unit controls a light intensity of the light emitted from the light emitting unit based on a temperature of the decoloring unit.

An erasing apparatus of an embodiment includes a reading unit, a printing unit, a transport unit, and a control unit. The reading unit reads an image formed on a sheet. The printing unit includes a plurality of nozzles that output colorants, and prints any one of a mark that is defined in advance or a code image of a machine-readable format on the sheet. The transport unit transports the sheet in order of the reading unit and the printing unit. The control unit detects an amount of deviation of the sheet generated on a transport path based on the image on the sheet which is read by the reading unit, selects which nozzle in the printing unit to output the colorant based on the amount of deviation, and controls the printing unit so as to perform printing from the selected nozzle.

A shading device includes: a shading member to pass a conveying path for conveying a recoding medium to plural image reading sections and reach the plural image reading sections; and a moving member to move the shading member between the plural image reading sections and a retracted position on the outside of the conveying path.

Flexible shading member for performing shading correction and movable relative to first and second image reading sections

According to an embodiment, a first discharging unit and a second discharging unit discharge a sheet. A first conveying path extends from a scanning unit to the first discharging unit. A second conveying path branches off from the first conveying path at a branch point of the first conveying path and extends to the second discharging unit. A conveying member discharges the sheet to the first discharging unit when a discharging destination of the sheet is the first discharging unit, and the conveying member makes part of the sheet project from the first conveying path to the first discharging unit, locates an upstream tip end of the sheet in a sheet conveying direction, at a position downstream in the sheet conveying direction from the branch point, and conveys the sheet to switchback to the second conveying path, when the discharging destination of the sheet is the second discharging unit.

Sheet sorting device and sheet sorting method

A sheet discharging device includes a first conveying path that guides a sheet to be conveyed. A second conveying path branches from the first conveying path. A sorting section sorts a sheet being conveyed on the first conveying path into either a downstream side of the branch point or the second conveying path. A first discharge tray is placed at a position downstream of the first conveying path and receives a sheet discharged from the first conveying path at a first sheet loading surface. A second discharge tray is placed at a position downstream of the second conveying path and below the first discharge tray, and receives a sheet discharged from the second conveying path at a second sheet loading surface whose distance to the first sheet loading surface increases toward a downstream side thereof in a sheet discharging direction.

Sheet discharging device and erasing device

A sheet feed apparatus which includes a sheet feed tray in which a plurality of sheets is loaded in piles; a sheet feed roller which is provided at a forward position of the sheet feed tray in a sheet feed direction, and sends the loaded sheets inside thereof; and a lift detection sensor which detects, by using a movable lever, a lift of a sheet bundle which occurs when the sheet bundle, of which a rear or a side in a sheet feed direction is bound, is sent by the sheet feed roller therein, the lift detection sensor being provided at a side position of the sheet bundle in a width direction and at a backward position with respect to the center of the sheet bundle in the sheet feed direction.
