DECOLORING DEVICE AND JAM DETECTION TIME CONTROLLING METHOD IN DECOLORING DEVICE

摘要

A decoloring device according to an embodiment includes a decoloring unit configured to decolor an image on a sheet. A scanner optically reads the sheet and generates image data corresponding to the read sheet. A storage unit stores a first jam detection time and a second jam detection time, the second jam detection time being longer than the first jam detection time. A first sensor detects a sheet being transported in a first transport area. A second sensor detects a sheet being transported in a second transport area. A jam determination unit determines occurrence of a jam in the first transport area based on a detection by the first sensor compared to the first jam detection time, and determines occurrence of a jam in the second transport area based on a duration of a detection by the second sensor compared to the second jam detection time.

1. A decoloring device comprising:
a decoloring unit configured to decolor an image on a sheet, the image being formed of a decolorable coloring agent; a scanner positioned on an upstream side of the decoloring unit in a sheet transport direction and configured to optically read the sheet and generate image data corresponding to the read sheet; a storage unit configured to store a first jam detection time which is a reference time for determining occurrence of a jam of a sheet in a first transport area of a transport path on an upstream side of an inlet of the decoloring unit in the sheet transport direction, and a second jam detection time which is a reference time for determining occurrence of a jam of a sheet in a second transport area of the transport path on a downstream side of the inlet of the decoloring unit in the sheet transport direction of the inlet of the de-coloring unit, the second jam detection time being longer than the first jam detection time; a first sensor configured to detect a sheet being transported in the first transport area; a second sensor configured to detect a sheet being transported in the second transport area; and a jam determination unit configured to determine occurrence of a jam of a sheet in the first transport area based on a duration of a detection of the sheet by the first sensor compared to the first jam detection time, and determine occurrence of a jam of a sheet in the second transport area based on a duration of a detection of the sheet by the second sensor compared to the second jam detection time.
