Embodiments of the present invention will be described below with reference to the drawings. Figure 1 is a front view of the use Kamisho management apparatus, Figure 2 is an enlarged front view of the sorting unit, Fig. 3 is a top view thereof. In the figure,
The sheet P conveyed from the copying machine main body F passes through a pair of conveying rollers 1 and a curved guide plate 2, is conveyed upward through a vertical conveying path by a plurality of conveying rollers 3 arranged in a vertical direction, and is sent to a bin 4. . The guiding of the paper P to the bins 4 arranged in multiple stages in the vertical direction is performed by switching the deflection claws 5 arranged at the entrances of the bins.

Reference numeral 6 denotes a jogger bar (sheet aligning means) which is provided upright so as to penetrate all the bins 4 and is movable in the notches 4a of the bins 4 shown in FIG. 5 and FIG. 6 show a plan view and a front view of the drive mechanism, respectively.
Drive force is transmitted through the belt 8 and the drive shaft 9.
To be driven.

When the paper P is discharged onto the bin 4, the jogger bar 6 moves in the direction of arrow A, pushes the paper P in the width direction, and stops at the end of the bin 4 opposite to the jog bar 6. Hit 10 After that, the yoga bar 6
Moves in the direction of arrow B, and is returned to the home position, whereby one sheet P aligning operation is performed. This operation is performed every time the sheet P is discharged onto the bin 4. The movement distance of the jogger bar 6 is naturally changed according to the size of the paper P. However, the change of the movement distance is performed by controlling the stepping motor 7 by the number of pulses corresponding to the paper size according to the received paper size signal. It is controlled by driving.

After the paper has been discharged and aligned for all the bins 4, the stopper 10 moves to the side of the bins 4, and the vertically movable chuck unit 11 shown in FIG. Retreat to a position where it does not interfere with Thereafter, the chuck unit 11 moves in the sheet bundle direction to grip the sheet bundle, and returns to the original position, whereby the sheet bundle is pulled out to the front. This bundle of sheets is stored in the check unit 11.
At the same time, the staple is stapled by a stapler (stapling means) 12 which can move up and down the sides of the bin 4 and then returned to the aligned position of the bin 4 by the check unit 11, at which point the stopper 10 also returns. This operation is repeated for all bins 4, and the sheet bundle on all bins 4 is stapled.

A paper pushing member (paper pushing means) 14 is provided on the bin end fluence 13, and this paper pushing member 14 is locked to one end of a lever 15 which rotates around a shaft 16 as a fulcrum. Normally, it is pressed against the bin end fence 13 by the torsion spring 17 in conjunction with the lever 15, and is housed in the recess of the bin end fence 13. After the stapling process is completed, the jog bar 6 is moved in the direction of the arrow B, thereby causing the lever 1 to move.
The other end of 5 also rotates in the direction B, and the sheet pushing member 14 having one end thereof pushes the stapled sheet bundle in the same direction as the transport direction. At this time, the stopper 10 is again brought into contact with the end face of the sheet bundle to guide the sheet at the time of pushing out, so that it is possible to always help to push out the sheet bundle straight.

As described above, the extrusion amount can be changed according to the paper size by controlling the pulse of the stepping motor 7, so that when the small-size paper is used, the extrusion amount is insufficient and it is difficult to take out the paper. There is no problem that the paper is pushed too much and dropped from the bin 4 in the case of large-size paper.

Reference numeral 18 denotes a paper sensor provided at the paper pushing position of the bin 4. When the paper sensor 18 detects the pushing of the bundle of paper, a lamp of a display unit (not shown) is turned on based on the detection signal. Then, the end of the job can be visually recognized more clearly.

FIG. 4 is a vertical sectional view of four rows of bins.
Has a bottom surface 4a on the base side and a bottom surface 4b on the tip side with the step 4c interposed therebetween.
