Abstract
A paper correction apparatus B corrects a curl of a sheet S by passing the sheet S through curved paper conveying routes CCP1 and CCP2 whose curving amounts can be changed. The paper correction apparatus B is provided with a control unit B3 which sets the curving amounts of the curved paper conveying routes CCP1 and CCP2, and changes a sheet interval in accordance with the curving amounts which are set. By this configuration, it is possible to inhibit the productivity from being reduced due to paper correction during performing post-printing processes in a finisher which is located in the downstream side of the paper correction apparatus B.
Claims17
A paper correction apparatus which corrects a curl of a sheet by passing the sheet through a curved paper conveying route whose curving amount is variable, comprising:
- a paper correction mechanism comprising an endless belt for conveying the sheet, a plurality of rollers, and a shaft, wherein the endless belt provides the curved paper conveying route and the shaft is configured to provide the curving amount of the curved paper conveying route;
- a plurality of roller pairs configured to convey the sheet;
- and
- a controller which sets the curving amount of the curved paper conveying route and increases or decreases a sheet interval in accordance with the set curving amount;
- wherein the sheet interval is changed by controlling the plurality of roller pairs to change a conveying speed of the sheet;
- and
- the plurality of roller pairs is provided upstream of the paper correction mechanism or downstream of the paper correction mechanism.
A non-transitory computer readable medium on which is recorded a program which corrects a curl of a sheet by passing the sheet through a curved paper conveying route whose curving amount is variable, and makes a paper correction apparatus perform:
- a first step comprising setting a curving amount of the curved paper conveying route;
- and
- a second step comprising increasing or decreasing a sheet interval in accordance with the set curving amount,
- wherein the paper correction apparatus comprises a paper correction mechanism comprising an endless belt for conveying the sheet through the paper correction mechanism and a cylindrical shaft, wherein the endless belt provides the curved paper conveying route and the cylindrical shaft is configured to provide the curving amount of the curved paper conveying route;
- a plurality of roller pairs configured to convey the sheet;
- wherein the sheet interval is changed by controlling the plurality of roller pairs to change the conveying speed of the sheet;
- and
- the plurality of roller pairs is provided upstream of the paper correction mechanism or downstream of the paper correction mechanism.
