Abstract
An image processing system includes an image forming unit, an image decoloring unit, a first sheet stacking unit, a second sheet stacking unit, a first detector for the first sheet stacking unit, a second detector for the second sheet stacking unit, and a control unit. The control unit controls a transport path of a sheet discharged from one of the image forming unit and the image decoloring unit.
Claims18
An image processing system comprising:
- an image forming unit;
- an image decoloring unit;
- first and second sheet stacking units;
- a first sheet detector for the first sheet stacking unit;
- a second sheet detector for the second sheet stacking unit;
- and
- a control unit configured to:
- control a transport path of a sheet discharged from one of the image forming unit and the image decoloring unit, so that:
- the sheet is transported to first stacking unit when:
- (i) the first sheet detector does not detect a sheet in the first stacking unit, (ii) the second sheet detector detects a sheet in the second stacking unit, and (iii) the sheet in the second stacking unit is a sheet discharged from the other one of the image forming unit and the image decoloring unit, and
- the sheet is transported to second stacking unit when:
- (i) the first sheet detector detects a sheet in the first stacking unit, (ii) the second sheet detector does not detect a sheet in the second stacking unit, and (iii) the sheet in the first stacking unit is a sheet discharged from the other one of the image forming unit and the image decoloring unit;
- and
- determine whether or not the sheet detected in the first or second stacking unit is a sheet discharged from the other one of the image forming unit and the image decoloring unit by comparing a current job with a previous job.

A sheet transport method comprising:
- detecting presence or absence of a sheet on a first sheet stacking unit;
- detecting presence or absence of a sheet on a second sheet stacking unit;
- controlling a transport path of a sheet discharged from one of an image forming unit and an image decoloring unit, so that
- the sheet is transported to the first stacking unit when:
- (i) the first sheet detector does not detect a sheet in the first stacking unit, (ii) the second sheet detector detects a sheet in the second stacking unit, and (iii) the sheet in the second stacking unit is a sheet discharged from the other one of the image forming unit and the image decoloring unit, and
- the sheet is transported to the second stacking unit when:
- (i) the first sheet detector detects a sheet in the first stacking unit, (ii) the second sheet detector does not detect a sheet in the second stacking unit, and (iii) the sheet in the first stacking unit is a sheet discharged from the other one of the image forming unit and the image decoloring unit;
- and
- determining whether or not the sheet detected in the first or second stacking unit is a sheet discharged from other one of the image forming unit and the image decoloring unit by comparing a current job with a previous job.
