Document Type and Number:
Japanese Patent JP5785524
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a color erasing apparatus that thermally treats a sheet by using a planar heater at a uniform temperature, thus allowing for uniform color erasing treatment.SOLUTION: The color erasing apparatus includes: a paper conveyance unit that conveys a sheet having an image formed by using a color material, which is erasable at a color-erasable temperature; a first heating unit that has a first planar heat source having a heating pattern part so that a heating temperature distribution becomes lower in the center than both sides in a sheet width direction orthogonal to a conveyance direction of the conveyed sheet, and heats the image formed on the sheet to become not lower than the color-erasable temperature by contacting a first surface of the conveyed sheet; a color erasing unit having a first pressing part to form a nip part through which the sheet passes together with the first heating unit, and to contact with a second surface of the sheet; a control unit that heats the first heating unit to not lower than the color-erasable temperature; and a stacking unit that is heated to not lower than the color-erasable temperature and on which the sheet subjected to the color erasing treatment is stacked.
