Abstract
According to embodiments, the image decolorizing device has a first heating conveying unit, a second heating conveying unit, and a guide. The first heating conveying unit has a first heating member that heats a first surface of the sheet and a first pressure member that presses the sheet to the first heating member. The second heating conveying unit has a second heating member that heats the second surface of the sheet and a second pressure member that presses the sheet to the second heating member. The guide is provided between the first heating conveying unit and the second heating conveying unit and that guides the sheet that is conveyed through the first heating conveying unit, to the second heating member of the second heating conveying unit.
Claims20
An image decolorizing device comprising:
- a first heating conveying unit that has a first heating member that heats a sheet to decolorize a color of a color material formed on a first surface of the sheet and a first pressure member that presses the sheet to the first heating member;
- a second heating conveying unit that has a second heating member that heats the sheet to decolorize a color of a color material formed on a second surface of the sheet and a second pressure member that presses a sheet to be passed therethrough against the second heating member;
- and
- a guide that is provided between the first heating conveying unit and the second heating conveying unit and positioned to guide a sheet to be conveyed through the first heating conveying unit, to the second heating member of the second heating conveying unit such that the sheet contacts the second heating member before contacting the second pressure member.
A method for decolorizing a color of a color material formed on a sheet comprising:
- decolorizing the color of the color material formed on a first surface of the sheet by heating the sheet by a first heating member while the sheet is pressed to the first heating member by a first pressure member;
- decolorizing the color of the color material formed on a second surface of the sheet by heating the sheet by a second heating member while the sheet is pressed to the second heating member by a second pressure member;
- and
- guiding the sheet, the first surface of which is decolorized by the first heating member, to the second heating member such that the sheet contacts the second heating member before contacting the second pressure member.
An image decolorizing device comprising:
- a first heating conveying unit that has a first heating member that heats a sheet to decolorize a color of a color material formed on a first surface of the sheet and a first pressure member that presses the sheet to the first heating member;
- a second heating conveying unit that has a second heating member that heats the sheet to decolorize a color of a color material formed on a second surface of the sheet and a second pressure member that presses the sheet to the second heating member;
- and
- a guide that is provided between the first heating conveying unit and the second heating conveying unit and that guides the sheet that is conveyed through the first heating conveying unit to, either the second heating member or the second pressure member that has lower surface-friction.
