Abstract
Sheets conveyed to a loading tray are stacked on the loading tray while they are sequentially aligned with an aligning unit, then, when pressing processing is performed with respect to a bundle of the stacked sheets, a presser is moved downward in a state where ends of the sheet bundle are abutting-held with the aligning unit. The sheet bundle is aligned by performing the pressing with a presser member gradually from a first reference fence side, to gradually discharge air staying in the sheet bundle from a first elastic body fence side.
Claims9
A paper jogging apparatus comprising:
- a loading tray that receives sheets and loads the sheets as a bundle of sheets;
- an aligning unit aligning side ends of the bundle of sheets loaded on the loading tray, and including a first elastic body fence having a first sheet abutting side and a first elastic body formed on the first sheet abutting side to align one side end of the bundle of sheets, and a first reference fence facing the first elastic body fence to align another side end of the bundle of sheets and having no elastic body;
- a pressing unit pressing the bundle of sheets from one surface thereof, and having a presser main body extending in a direction from the first elastic body fence toward the first reference fence and a presser member having one end swingably attached to a lower surface of the presser main body adjacent to the first elastic body fence and extending from one end of the presser main body toward another end thereof while passing under the lower surface of the presser main body;
- a support unit situated under the pressing member to form an interval therebetween and supporting another surface of the bundle of sheets;
- and
- a controller that performs pressing with respect to the bundle of sheets by moving the pressing unit in a direction narrowing the interval between the pressing unit and the support unit in a state where the aligning unit abutting-holds the bundle of sheets,
- wherein when the presser member does not press the bundle of sheets, the presser member is inclined such that the one end of the presser member adjacent to the first elastic body fence is positioned away from a position of pressing the bundle of sheets more than another end of the presser member adjacent to the first reference fence, and when the presser member presses the bundle of sheets, the another end of the presser member gradually moves upwardly to completely abut on an upper surface of the bundle of sheets, thereby pressing the bundle of sheets.

A paper jogging apparatus comprising:
- a loading tray receiving sheets and loading the sheets as a bundle of sheets;
- an aligning unit aligning ends of the bundle of sheets loaded on the loading tray, and including an elastic body fence having a sheet abutting side and a plurality of elastic bodies formed on the sheet abutting side to align one end of the bundle of sheets, the plurality of elastic bodies vertically extending to be spaced from the sheet abutting side to form a step part and being spaced from each other in a direction parallel to the one end of the bundle of sheets, and a reference fence facing the elastic body fence to align another end of the bundle of sheets and having no elastic body;
- a pressing unit provided along an aligning direction of the aligning unit and having a presser member to press the bundle of sheets from one surface thereof;
- a support unit situated under the pressing member to form an interval therebetween and supporting another surface of the bundle of sheets;
- and
- a controller that performs pressing with respect to the bundle of sheets by moving the pressing unit in a direction narrowing the interval between the pressing unit and the support unit in a state where the aligning unit abutting-holds the bundle of sheets,
- wherein when the presser member does not press the bundle of sheets, the presser member is inclined such that one end of the presser member adjacent to the elastic body fence is positioned away from a position of pressing the bundle of sheets more than another end of the presser member, and when the presser member presses the bundle of sheets, the another end of the presser member gradually moves upwardly to completely abut on an upper surface of the bundle of sheets, thereby pressing the bundle of sheets to release air between the sheets pushed with the presser member through the step part.
