Image decoloring device
First Claim
1. An image decoloring device comprising:
- a decoloring processing unit configured to remove a color of a decolorable colorant that forms an image on a sheet by applying heat to the sheet;
a sheet carrying unit configured to convey the sheet through the decoloring processing unit; and
a processor configured to;
determine a selection of a decoloring mode of the decoloring processing unit as one of a normal mode and a power-saving mode, andcontrol the decoloring processing unit and the sheet conveying unit to perform decoloring processing in accordance with the selected decoloring mode, whereinwhen the selected decoloring mode is the normal mode, the processor performs the decoloring processing by controlling the decoloring processing unit to apply heat at a first temperature to the sheet and controlling the sheet carrying unit to convey the sheet through the decoloring processing unit at a first speed, andwhen the selected decoloring mode is the power-saving mode, the processor performs the decoloring processing by controlling the decoloring processing unit to apply heat at a second temperature lower than the first temperature to the sheet and controlling the sheet carrying unit to convey the sheet through the decoloring processing unit at a second speed slower than the first speed.

Abstract
An image decoloring device operates in a power-saving mode and in a normal mode. The image decoloring device includes a decoloring processing unit which removes a color of a decolorable colorant that forms an image on a sheet by applying heat to the sheet. A sheet carrying unit conveys the sheet through the decoloring processing unit. A processor controls the sheet carrying unit. If the image decoloring device is operating in the power-saving mode, a conveyance speed of the sheet through the decoloring processing unit is a first speed. If the image decoloring carrying unit is operating in the normal mode, the conveyance speed of the sheet through the decoloring processing unit is a second speed greater than the first speed.

5. A method of controlling an image decoloring device which performs decoloring processing in a power-saving mode and in a normal mode, the method comprising the steps of:
-
determining a decoloring mode for the decoloring processing as one of the power-saving mode and the normal mode; conveying a sheet through a decoloring processing unit, wherein when the determined decoloring mode is the normal mode, the sheet is conveyed at a first speed, and when the determined decoloring mode is the power-saving mode, the sheet is conveyed at a second speed slower than the first speed; and decoloring, with the decoloring processing unit, a color of a decolorable colorant that forms an image on the sheet by applying heat to the sheet, wherein when the determined decoloring mode is the normal mode, the decoloring processing unit applies the heat at a first temperature to the sheet, and when the determined decoloring mode is the power-saving mode, the decoloring processing unit applies the heat at a second temperature lower than the first temperature to the sheet. - View Dependent Claims (6, 7, 8)
