Abstract

<P>PROBLEM TO BE SOLVED: To solve a problem that in a conventional sheet bundle aligning device, the conveying direction of a sheet bundle and the direction crossing the conveying direction are aligned at the same time, and either of the directions is not fully aligned, which causes non-alignment of sheet bundles. <P>SOLUTION: After a plurality of sheets having been conveyed are aligned in the direction crossing the sheet conveying direction, driving is controlled so that the sheets are aligned in the sheet aligning direction. <P>COPYRIGHT: (C)2004,JPO

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a sheet bundle aligning device in an image forming apparatus such as a printer, a facsimile, and a composite device thereof.
[0002]
[Prior art]
FIG. 4 is a schematic configuration showing a conventional sheet bundle aligning apparatus, and FIG. 5 is a schematic configuration diagram showing an operation of aligning a sheet bundle.
[0003]
In FIG. 4, the reference matching member 1 is driven by a driving means 1a such as a motor or a belt, the shifting alignment member 2 facing the reference matching member 1 is driven by a driving means 2a such as a motor or a belt, and the shifting matching member 3 is driven by a driving means. 3a, each of which is located at a selected reference position. Further, one or a plurality of sheet bundles 4 on which an image is formed by an image forming apparatus (not shown) are conveyed to a sheet stacking member 5. The reference alignment member 6 is fixed at a position facing the alignment member 3.
5, when the sheet bundle 4 is aligned, after the sheet bundle 4 is conveyed to the sheet stacking member 5, the shift aligning member 2 is driven by the driving unit 2a, and the shift alignment member 3 is shifted by the driving unit 3a. Move to a predetermined position where alignment should be performed. At this time, the sheet bundle 4 is sandwiched by the reference alignment member 1 and the shift alignment member 2 so that the sheet bundle 4 is aligned in a direction intersecting the conveying direction, and at the same time, the sheet bundle 4 is fixed at the illustrated position. The sheet bundle 4 is nipped by the alignment member 6 and the alignment member 3 to align the sheet bundle 4 in the transport direction. Thereafter, the alignment members 2 and 3 are moved to the selected reference position shown in FIG. 4 in preparation for aligning the next conveyed sheet bundle (not shown).
[0004]
[Problems to be solved by the invention]
Since the sheet bundle aligning device simultaneously performs the alignment of the sheet bundle in the transport direction and the direction intersecting the transport direction, alignment in any direction is not sufficiently performed, and the alignment of the sheet bundle is disturbed. was there.
[0005]
[Means for Solving the Problems]
The present invention has a configuration in which one or a plurality of conveyed sheets are aligned in a direction crossing the sheet conveyance direction, and then drive control is performed to align the sheets in the sheet conveyance direction. This solves the above problem.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described with reference to the accompanying drawings. FIG. 1 is a configuration diagram showing a configuration of a sheet bundle aligning apparatus according to the present invention, and FIGS. 2 and 3 are schematic configuration diagrams showing an operation of aligning a sheet bundle.
[0007]
In FIG. 1, the reference matching member 1 is driven by a driving means 1a such as a motor or a belt, the shifting alignment member 2 facing the reference matching member 1 is driven by a driving means 2a such as a motor or a belt, and the shifting matching member 3 is driven by a driving means. 3a, each of which is located at a selected reference position. One or more sheet bundles 4 on which an image is formed by an image forming apparatus (not shown) are conveyed to a sheet bundle stacking member 5. The reference alignment member 6 is fixed at a position facing the alignment member 3.
In FIG. 2, after the sheet bundle 4 is conveyed to the sheet bundle stacking member 5, the alignment member 2 is moved by the driving unit 2a to a predetermined position where the sheet bundle 4 is to be aligned. At this time, the sheet bundle 4 is sandwiched by the reference alignment member 1 and the shift alignment member 2, and the alignment in the direction intersecting the transport direction of the sheet bundle 4 is reliably performed.
[0008]
In FIG. 3, the alignment member 3 is moved by the driving means 3a to a predetermined position where the alignment of the sheet bundle 4 is to be performed. At this time, the sheet bundle 4 is sandwiched by the reference alignment member 6 and the alignment member 3 fixed at the positions shown in the drawing, and the alignment of the sheet bundle 4 in the transport direction is reliably performed. Thereafter, the shift alignment members 2 and 3 move to the selected reference position shown in FIG. 1 in preparation for aligning the next conveyed sheet bundle (not shown).
[0009]
【The invention's effect】
As described above, the sheet bundle aligning apparatus of the present invention can align both the sheet conveying direction to be aligned and the direction intersecting the sheet conveying direction, so that the sheet bundle can be surely aligned. Can be done.
