An image erasing apparatus includes a scanning unit, a memory unit, an erasing unit, and a carrying unit. The scanning unit converts an image formed on a sheet into image data which is electronic data. The memory unit stores the image data converted by the scanning unit. The erasing unit erases the image formed on the sheet. The carrying unit carries the sheet to the scanning unit and the erasing unit in this order.

There is provided a decoloring device including a decoloring unit, a first sheet conveying unit, a pre-decoloring reading unit, a type determining unit, a second sheet conveying unit, a post-decoloring reading unit, a decoloring success or failure determining unit, and a determination criterion setting unit. The type determining unit determines the type of image on the sheet conveyed to the decoloring unit based on the reading result in the pre-decoloring reading unit. The post-decoloring reading unit reads an image on the sheet after the decoloring, which is conveyed by the second sheet conveying unit. The decoloring success or failure determining unit determines whether or not the decoloring in the decoloring unit is successful based on the reading result in the post-decoloring reading unit. The determination criterion setting unit sets a determination criterion in the decoloring success or failure determining unit, based on the type of image, which is determined by the type determining unit.

There is provided a decoloring device including a decoloring unit, a first sheet conveying unit, a second sheet conveying unit, a reversing and conveying unit, a manual feed tray, and a manual discharge tray. The reversing and conveying unit is disposed adjacent to an outer wall of the decoloring device in relation to the first sheet conveying unit, and conveys once again the sheet, which is temporarily brought into the second sheet conveying unit after being decolored by the decoloring unit and is switch-back conveyed, to the first sheet conveying unit. The manual feed tray is provided at an outer wall side of the decoloring device adjacent to the reversing and conveying unit. The manual discharge tray is provided at a position of the outer wall side of the decoloring device adjacent to the reversing and conveying unit.

A color erasing apparatus includes a conveyance member to convey a sheet on which an image is formed of a color erasable coloring material, a color erasing part to erase a color of the coloring material of the image formed on the sheet conveyed by the conveyance member, a control part that counts the processed number of sheets images of which are color-erased by the color erasing part and determines whether the processed number of sheets exceeds a previously set threshold, and a notification interface to output a signal for notifying that, cleaning of the color erasing part is required if the processed number of sheets exceeds the threshold.
摘要:
A sheet conveyance control method in an apparatus including a first conveying path for leading a sheet from a feeing port to a discharge port, a second sheet conveying path for leading the sheet to another conveyance destination, and a decoloring processing section configured to decolor an image formed on the sheet includes: detecting the length of the sheet further on a downstream side than the feeding port and further on an upstream side than a branching point of the first and second sheet conveying paths in a sheet conveying direction of the first sheet conveying path; and changing, if the trailing end of the sheet is not detected in a period after the leading end of the sheet is detected and before the leading end of the sheet reaches the branching point, a first flapper to a state in which the sheet is conveyed to the discharge port.
摘要:
When the presence or absence of a malfunction is respectively determined in a decoloring section or a separation device, and it is determined that either the decoloring section or the separation device is malfunctioning, only the other is executable.
摘要:
A communication unit transmits image data of a preceding sheet scanned to a management device communicating with a decoloring device and receives from a management device determination data which is produced by the management device based on the image data and indicates at least whether or not the preceding sheet is reusable and receives ability data of the management device or reception time indication data. A control unit conveys the preceding sheet to a predetermined conveyance destination based on the determination data and feeds sheets at a timing at which the leading end of a following sheet does not run into the tail end of the preceding sheet even if the preceding sheet is held until the determination data is received based on the ability data or the reception time indication data.
摘要:
According to one embodiment, an erasing apparatus including a recording medium removing apparatus includes: a thickness determining unit configured to determine whether the thickness of a recording medium is equal to or larger than a first threshold, a conveyance guide forming a conveying path for the recording medium; a conveyance guide displacing device configured to lift the conveyance guide if the thickness determining device determines that the thickness of the recording medium is equal to or larger than the first threshold, and a removing mechanism configured to remove, from a recording medium conveying path, the recording medium determined as unconveyable.
