Figure 1 is a front view showing an example of use Kamisho management apparatus according to the present invention, FIG. 2 is a plan view of the embodiment, FIG. 3 is an explanatory view schematically showing the operation of the sheet aligning member.

In FIG. 1, a recording apparatus (copier) body 1
Although not shown, a photoconductor drum, a charged CG, a transport belt, a cleaning, a fixing unit, a scanner, and the like are provided.

A sorter 2 to which a sheet is conveyed from a sheet discharge roller 11 of the copying machine body 1 is connected. The sorter 2 is provided with a branching claw 12, and when no post-processing is required, the sheet P discharged from the paper discharge port of the copying machine is guided upward by the branching claw 12 and directly to the discharge tray 14. Is discharged. Reference numeral 15 denotes a conveyance path, and 16 denotes a conveyance roller.

The paper feeding device 4 has bins 2 arranged in multiple stages.
The reference numerals 0 and 20 are provided so as to be inclined such that the left side is upward in FIG. When the sheet P discharged from the sheet discharge port of the copying machine main body 1 is guided downward by the branching claws 12, the sheet P is conveyed along the bin-side conveying path 13 by the conveying rollers 17, and is transferred to the bin 20 by the conveying rollers 18. Stacked. Reference numeral 21 denotes a helical spiral shaft for moving the multi-stage bin 20 to a discharge position and a staple position, and reference numeral 40 denotes a stapler for stapling the aligned paper.

The sheet bundle P discharged from the image forming apparatus and stacked on each bin 20 is rocked one by one by a sheet aligning member 30 as shown in FIG. Surface). The chuck device 50 has two pairs of upper and lower arms, which open and close simultaneously. The sheet (bundle) P has its end face sandwiched between two places by the upper and lower arms. The stapler 40 is fixed to a moving unit 51. The moving portion 51 moves parallel to the stay groove 52 in the parallel portion along the guide groove.
The inclined portion is configured to perform rotational movement by moving along the inclined portion. Further, the stay member 52 is provided in parallel with the rear end of the bin 20, whereby the moving unit 51 can move in parallel with the rear end of the stacked sheet bundle P, and near the front end face of the sheet bundle P. It is possible to perform several bindings at an arbitrary position at the rear end of the sheet bundle P by pulse control of a drive motor.

The sheet aligning member 30 is driven by a drive motor (not shown). In this embodiment, a stepping motor is used to simplify the position control. When the discharge bin for the next sheet is changed, the helical spiral shaft 21 or a drive motor (not shown) rotates forward or reverse, the discharge bin position moves to the upper or lower bin, and sorting and collating are performed.

Next, the operation of the above embodiment will be described.

The sheet discharged from the copying machine main body 1 is transported to a sorter 2. In the case of the sort stack mode, the sheet is guided to the bins 20 arranged in multiple stages, and this operation will be described first.

The paper P discharged from the copying machine main body 1 is guided to the bin-side conveyance path 13 by the branching claws 12, and is discharged and stacked by the conveyance rollers 17 and 18 onto the bin 20 at the discharge position. . The discharged paper P is aligned on the bin 20 by the paper alignment member 30. When the discharge bin 20 of the next sheet P changes, the helical spiral shaft 21 is rotated forward or backward by a drive motor (not shown), and the position of the discharge bin 20 moves to the upper or lower bin 20 position, sorting, collating. Is performed.

As shown in FIGS. 2 and 3, the paper aligning member 30 is stopped at a predetermined standby position a when the paper P is discharged. The standby position a starts the aligning operation after a predetermined time has elapsed after the discharge of the paper P that differs depending on the paper size. When the next paper to be discharged is higher than the current discharge position,
The bin 20 moves downward, and the paper alignment member 30 moves to a position b where it does not contact the aligned paper, and after a predetermined time,
Retreat to the standby position a. In other words, the aligning operation in the mode in which the bin descends repeats the reciprocating movement between the positions a and b. Here, the distance lb from the position b to the sheet end surface
Is the minimum distance that does not cause a conventional problem.
b = 3 mm.

Next, when the paper to be discharged is the same as or lower than the current discharge position, or at the end of the aligning operation cycle in the bin lowering mode, that is, when the bin 20 moves upward or does not move, alignment is performed. The paper alignment member 30 is moved to the over-feed position c in the same manner as the conventional operation in order to surely perform the operation, and after a predetermined time,
It retreats to the standby position a and repeats this. Where position c
The excess feed amount lc is an amount that can surely align papers such as curls. In the embodiment, lc = 3 mm.

Since the control is performed such that the amount of shift by the sheet aligning member 30 is changed between the times described above, the sheets P can be aligned without causing the sheet P to be displaced when descending.

According to the above embodiment, when the bin 20 descends
The paper alignment member 30 to the position before the paper width in the alignment direction.
At the time other than when the bin 20 is lowered.
0 is controlled so as to be excessively larger than the paper width in the alignment direction, so that the paper P can be aligned without causing the paper P to be displaced when descending.

According to the above-described embodiment, at the end of the discharge cycle when the bin 20 is lowered, the paper alignment member 30 is moved in the alignment direction.
Since the paper is controlled to be excessively wider than the paper width , it can be surely aligned even when the bin 20 is lowered.

According to the above embodiment, when the bin is raised, and when
Since the paper alignment control for the inactive mode is the same , bin 2
Alignment can be performed reliably even at zero stop.

[0029]

According to the first aspect of the present invention, the amount of movement of the sheet aligning member when the bin is lowered and at other times is controlled, so that the sheet does not shift when the bin is lowered. It is possible to align.

According to the second aspect of the present invention, since the paper alignment member is excessively moved beyond the paper width in the alignment direction at the end of the paper discharge cycle at the time of lowering the bin, it is ensured even when the bin is lowered. Can be aligned.
