Even if an elastic member is provided between the contact member 700 and the first advance member 610 and a spring is further arranged on the rotating shaft 612 (see FIG. 5) to absorb the impact in a double manner. Good.
On the other hand, as a comparative example, even when a spring is provided only on the rotating shaft 612 and the contact member 700 and the entire first advance member 610 are integrated into a contact movable portion (not shown), the contact portion advances with respect to the paper P. Although it is possible, if the contact movable part is integrated, the impact received on the side of the paper is not absorbed by the side of the paper, but is absorbed by the rotation shaft 612, which is the rotation fulcrum. Rigidity of moving parts is required. In this case, the load on the rotating shaft 612 becomes large, which is not suitable.

The support portion 300, the first advance member 610, and the contact member 700 will be further described with reference to FIG. 14 (a diagram illustrating the configuration of the contact member 700 and the like). The state shown in FIG. 14 is the same as the state shown in FIG.
As shown in FIG. 14, the advance portion 614 provided in the first advance member 610 is formed so as to extend in one direction, and has an end portion 614E on the downstream side in this one direction.

More specifically, for example, when the paper P is taken out, the paper P may be taken out in the direction indicated by the arrow 4B in FIG. 4, and at this time, the downstream portion 785 of the contact member 700 is taken out. The paper P may come into contact with the paper P.

In this case, if the wide portion 785A is provided as in the present embodiment, the contact member 700 is less likely to be damaged as compared with the case where the wide portion 785A is not provided.
More specifically, when the wide portion 785A is provided, the portion of the contact member 700 where stress is generated becomes a wider range, and the contact member 700 is less likely to be damaged.
Although FIG. 14 has described the configuration of the first advance member 610 side located on one side of the paper P, as described above, in the present embodiment, the first advance member 610 side and the second advance member 620 side are It has the same configuration, and a wide portion 785A is also provided on the second advance member 620 side.
When an excessive force is applied, the contact member may move extremely obliquely so that only the downstream portion 785 is close to the advance portion 614 of the advance member 610. However, even if it moves extremely diagonally, the downstream portion 785 extends to the downstream side of the advancing member 610B, so that the end portion of the contact member 700 does not abut on the advancing member 610B. If they hit each other, the contact member 700 may become difficult to move, and if the contact member 700 has a lower rigidity than the advance member 610, the contact member 700 may crack. By the way, in this embodiment, there are two protrusions 740 so that the contact member 700 does not move extremely diagonally with respect to the advance portion 614 of the advance member 610, and the shape of the spring is the coil spring KB1. When using it, it is difficult to move diagonally.

Since the thickness is small, the contact member 700 is easily deformed.
On the other hand, as described above, if the tapered surface TM is located in the contact member 700 where it does not come into contact with the root side coil spring KB2 and the tip side coil spring KB1, the deformation of the contact member 700 is suppressed. To.

FIG. 10 is a view when the support portion 300, the paper P, the second advance member 620, and the contact member 700 are viewed from the direction indicated by the arrow X in FIG.
In the present embodiment, the second advance member 620, which is the side that receives the paper P, is arranged above the already loaded paper PX as described above.
Further, as described above, in the present embodiment, the contact member 700 is placed on the already loaded paper PX, and the lower edge portion 709 of the contact member 700 is in contact with the already loaded paper PX.

Here, in the present embodiment, the lower edge portion 709 is arranged along the surface of the already loaded paper PX, and the lower edge portion 709 and the already loaded paper PX are in line contact with each other.
Further, in the present embodiment, when the lower edge portion 709 is in contact with the already loaded paper PX, the parallelism between the lower edge portion 709 and the already loaded paper PX is the lower edge portion of the second advance member 620. It is higher than the parallelism between the 610E and the loaded paper PX.

Here, in the present embodiment, the first advance member 610, which is the side that presses the paper P, is arranged in the state shown in FIG. 6, for example.
Further, the second advance member 620, which is the side receiving the paper P, is arranged in the state shown in FIG. 10, and the second advance member 620 is in a state along the already loaded paper PX rather than the first advance member 610. Be placed.

In addition, in the present embodiment, the wire L11 connecting the central axes C2 of the tip side coil spring KB1 and the root side coil spring KB2 provided on the first advance member 610 side and the edge portion PB of the paper P are formed. As shown in FIG. 6, the angle is the angle α.
On the other hand, the angle formed by the line L21 connecting the central axes C21 of the tip side coil spring KB1 and the root side coil spring KB2 provided on the second advance member 620 side and the edge portion PB of the paper P is shown in FIG. As shown in 10, the angle β is obtained.
In the present embodiment, the first advance member 610 and the second advance member 620 are arranged so that the angle α is larger than the angle β.

Further, in the present embodiment, on the second advance member 620 (see FIG. 10) side, the load acting on the second advance member 620 side from the newly supplied paper P (not shown in FIG. 10) is applied to the coil spring. It is received by the KB, but at this time, in the present embodiment, the load is received by the two coil springs KB1 of the tip side coil spring KB1 and the root side coil spring KB2.
On the other hand, also on the side of the first advance member 610 (see FIG. 6), the load due to the reaction from the paper P is received by the coil spring KB. At this time, in the present embodiment, this load is mainly applied. Received by the tip side coil spring KB1.

Here, on the second advance member 620 (see FIG. 10) side, which is the receiving side, the load is received by the two coil springs KB as described above, so that the load acting on the individual coil springs KB becomes smaller. In this case, the contact member 700 provided on the second advance member 620 side becomes difficult to move, and the positioning of the paper P by the contact member 700 is made more stable.
Further, if the contact member 700 is configured to be difficult to move, the already loaded paper PX located below the contact member 700 and in contact with the contact member 700 is difficult to move.

Further, in the present embodiment, when the paper P is pressed against the contact member 700 that functions as a receiving portion for receiving the paper P, the contact member 700 is centered on the lower edge portion 709 (see FIG. 9). , Easy to rotate in the direction indicated by arrow 9F.
In addition, in the present embodiment, the lower edge portion 709 of the contact member 700 comes into contact with the already loaded paper PX and receives a drag force from the paper P so that it is difficult to move. On the other hand, the portion of the contact member 700 located above the lower edge portion 709 is pressed by the new paper P and tends to fall in the direction indicated by the arrow 9F.
In this case, the already loaded paper PX located below the contact member 700 becomes difficult to move. Then, in this case, the misalignment of the already loaded paper PX due to the movement of the lower edge portion 709 of the contact member 700 is less likely to occur.

Further, in the present embodiment, as described above, the contact member 700 is provided with the tapered surface TM, which makes it easier for the contact member 700 to fall down.
In addition, in the present embodiment, the tapered surface TM is attached to the surface of the contact member 700 located on the side where the contact member 700 falls, so that the contact member 700 is more likely to fall.

On the other hand, on the first advance member 610 (see FIG. 6) side, the load caused by the reaction from the paper P is mainly received by the tip side coil spring KB1.
In this case, the amount of contraction of the tip side coil spring KB1 becomes large, and the contact member 700 moves greatly. In this case, the load acting on the paper P from the first advance member 610 side is reduced.

Here, if the load acting on the paper P is large, the paper P may be wavy and deformed, or when the load is released, the paper P may bounce and the alignment may be disturbed. Further, if the load acting on the paper P is large, the edge PB of the paper P may be broken.
On the other hand, in the present embodiment, the load acting on the paper P is reduced, and problems that occur when a large load is applied to the paper P are less likely to occur.

Here, the size of the paper P often varies, and the paper P larger than the specified value may exist.
In this case, the paper P larger than this specified value is excessively pressed by the first advance member 610 and the second advance member 620, and in this case, the paper P may be deformed or the paper P may be disturbed. ..

On the other hand, in the present embodiment, when the paper P larger than the specified value is present, the contact member 700 is retracted from the paper P.
In addition, when the paper P larger than the specified value is present, the contact member 700 moves in the direction opposite to the advancing direction of the first advancing member 610 and the second advancing member 620.
As a result, the excessive load applied to the paper P is suppressed, and the deformation of the paper P and the disorder of the paper P are suppressed.

In the present embodiment, the amount of movement of the contact member 700 provided on the advance side (the amount of retreat from the paper P) is larger than the amount of movement of the contact member 700 provided on the receiving side.
In this case, the receiving side can position the paper P more accurately, and the advancing side can release the load acting on the paper P.

In the present embodiment, as shown in FIG. 8, when both the first advance member 610 and the second advance member 620 are advanced with respect to the paper P, the movement amount of the contact member 700 is similarly increased. The amount of evacuation from the paper P) is increased, and the load acting on the paper P is reduced.
When both the first advance member 610 and the second advance member 620 are advanced to the paper P, the tip side coil spring KB1 is mainly subjected to a load due to the reaction from the paper P.
In this case, the contact member 700 moves significantly, and the load acting on the paper P from the first advance member 610 and the second advance member 620 is reduced.

Further, in the present embodiment, a storage unit for accumulating the paper P conveyed from the upstream side is provided while the paper P is being aligned using the first advance member 610 and the second advance member 620. ing.
More specifically, in the present embodiment, from the start of advancement of one or both advancement members 600 of the first advance member 610 and the second advance member 620 until the advancement member 600 returns to the original position. In addition, new paper P may be conveyed from the upstream side toward the support portion 300, and in this case, in this embodiment, the new paper P is temporarily stored in the storage portion.

Specifically, in the present embodiment, the paper accumulating unit 60 (see FIG. 2) functions as an accumulating unit, and the advancing member 600 is the original after the advancing of one or both of the above advancing members 600 is started. Before returning to the position of, a plurality of new sheets P are accumulated in the sheet stacking unit 60.
In addition, in the present embodiment, the plurality of sheets P that have reached the paper stacking unit 60 between the start of advancement of one or both advancement members 600 and the return of the advancement member 600 to the original position are formed. It is stored in the paper stacking unit 60.
Then, in the present embodiment, when the advanced advance member 600 returns to the original position, the plurality of sheets P stored in the paper accumulating unit 60 are sent to the first loading unit 43.

Here, for example, if a configuration in which a plurality of sheets of paper P are not accumulated in the paper stacking unit 60, it is necessary to temporarily stop the image forming process in the image forming apparatus 2 (see FIG. 1). ..
More specifically, while the first loading unit 43 is performing the alignment processing of the paper P, the transport of the paper P toward the first loading unit 43 is delayed. In this case, the image forming apparatus 2 is used. Under the influence of this, it becomes necessary to perform processing such as temporarily stopping the image forming process.
On the other hand, when a plurality of sheets of paper P are stored in the paper stacking unit 60 as in the present embodiment, the influence on the image forming apparatus 2 is smaller than that in the case where the sheets are not stored, and the entire image forming system 1 is performed. Processing efficiency can be improved.

In the above, both the first advance member 610 and the second advance member 620 are provided with a function of pressing the paper P and a function of receiving the paper P, but one of the advance members 600 is provided with the paper P. It is possible to give only the function of pressing and the other advancing member 600 to have only the function of receiving the paper P.
In addition, in the above, both the first advance member 610 and the second advance member 620 are provided with a function of advancing and retreating with respect to the paper P. By the way, not limited to this, only one advancing member 600 of the first advancing member 610 and the second advancing member 620 is provided with a function of advancing and retreating with respect to the paper P, and the other advancing member 600 is provided with a function of advancing and retreating. The other advancing member 600 may be provided in a fixed state without being provided.

In this case, since the advancing member 600 provided in the fixed state does not have the advancing function, it is not regarded as an advancing member, but is arranged on the downstream side of the paper P moving along the width direction. It can be regarded as an arrangement member.
In addition, the advancing member 600 provided in the fixed state can be regarded as an disposing member arranged on the downstream side in the paper moving direction with respect to the advancing member 600 pressed by the other advancing member 600 and moving. ..

In addition, in this case, the advancing member 600 located on the side that presses the paper P can be regarded as a moving means for moving the paper P supported by the support portion 300 in the width direction of the paper P. ..
Further, the advancing member 600 provided in the fixed state can be regarded as an arranging member arranged on the downstream side in the paper moving direction with respect to the paper P moved by the moving means.

Further, in this case, the arrangement member side receives the paper P moved by the moving means by using the contact member 700 provided on the arrangement member side.
Here, in this case, the contact member 700 is arranged between the paper P and the arrangement member that are moved by the moving means.
In addition, on the side receiving the paper P, a member such as the contact member 700 may not be provided, and for example, a wall portion along the vertical direction may be provided and the paper P may be abutted against the wall portion.

The process for loading the paper P will be further described.
In the present embodiment, the CPU 111 (see FIG. 12), which is an example of the processor, positions at least a part of the contact member 700 in the vertical direction based on the information about the paper P supported by the support portion 300. change.
In other words, the CPU 111 sets the rotation angle of the contact member 700 about the rotation shaft 612 (FIG. 5) based on the information about the paper P loaded on the support portion 300. Then, the CPU 111 rotates the contact member 700 so that the contact member 700 is arranged at the set rotation angle.

Here, the information about the paper P loaded on the support unit 300 is input by the user, for example, via an operation panel (not shown). The CPU 111 acquires the information about the paper P by obtaining this information input by the user.

Here, in the present embodiment, when the paper P loaded on the support portion 300 is a specific paper P such as thin paper, the CPU 111 is indicated by reference numeral 15A in FIG. 15 (a diagram showing the state of the support portion 300). As described above, the support portion 300 is lowered as compared with the case where the paper is not the specific paper P.
In other words, when the paper P loaded on the support portion 300 is a specific paper P such as thin paper, the CPU 111 increases the amount of descent of the support portion 300 as compared with the case where the paper P is not the specific paper P.

More specifically, in the present embodiment, when the sensor S shown in FIG. 15 detects the highest-ranked paper among the papers P loaded on the support portion 300, the CPU 111 lowers the support portion 300. Let me.
At this time, in the present embodiment, when the paper P loaded on the support portion 300 is a specific paper P, the amount of lowering when performing this lowering is increased.

Although the description is omitted above, in the present embodiment, as shown in FIG. 15, a sensor S for detecting the uppermost paper P among the papers P mounted on the support portion 300 is provided.
In the present embodiment, when the paper P is sequentially loaded on the support portion 300, the uppermost paper P among the paper P reaches the detection position by the sensor S. As a result, the top-level paper P among the paper P loaded on the support portion 300 is detected by the sensor S.
Then, in the present embodiment, as described above, when the top-level paper P is detected by the sensor S, the support portion 300 is lowered. At this time, in the present embodiment, when the paper P loaded on the support portion 300 is a specific paper P, the amount of lowering when the support portion 300 is lowered becomes large.

In other words, when the paper P loaded on the support unit 300 is a specific paper P, the CPU 111 increases the amount of descent of the support unit 300 at one time.
In this case, it is possible to prevent the number of sheets of paper P that can be processed per unit time from decreasing.
Here, in the present embodiment, when the paper P loaded on the support portion 300 is a specific paper P such as thin paper, the frequency with which the support portion 300 descends increases, and the paper P that can be processed per unit time. There is a risk that the number of sheets will decrease.

More specifically, when the paper P loaded on the support portion 300 is a specific paper P such as thin paper, the paper P is likely to be curled or the like. In this case, the load height of the paper P in the support portion 300 tends to be larger than that of the paper P in which curling and the like are unlikely to occur.
In other words, when the same number of sheets of paper P are loaded on the support portion 300, when a specific sheet P such as thin paper is loaded, the case where a sheet P other than the specific sheet P is loaded is compared with the case where the sheet P other than the specific sheet P is loaded. The loading height of paper P tends to be large.
In this case, the detection of the paper P by the sensor S is likely to be performed frequently, and the frequency with which the support portion 300 is lowered increases accordingly.

Here, it takes time for the support portion 300 to descend. Further, while the support portion 300 is being lowered, it is necessary to temporarily stop the processing in the image forming apparatus 2 and the processing in the paper processing apparatus 3.
In this case, the number of sheets of paper P that can be processed per unit time decreases, and the processing efficiency decreases.
On the other hand, when the amount of lowering of the support portion 300 is increased as in the present embodiment, the frequency of lowering of the support portion 300 is reduced, and the processing efficiency is lowered due to the lowering of the support portion 300. Can be suppressed.

On the other hand, if the amount of lowering of the support portion 300 is increased, the position of the paper P resting on the support portion 300 is lowered, making it difficult for the contact member 700 to come into contact with the paper P, or the contact member 700 to come into contact with the paper P. It disappears.
More specifically, when the amount of lowering of the support portion 300 is increased, the contact member 700 and the paper P are arranged in the positional relationship shown in FIG. 15, for example. In this case, the contact member 700 is less likely to come into contact with the paper P, or the contact member 700 is less likely to come into contact with the paper P.

On the other hand, as described above, if the positions of the contact member 700 and the paper P are changed in the vertical direction at least a part of the positions of the contact member 700 based on the information about the paper P, the contact member 700 and the paper P are shown in FIG. It is arranged in the state shown in (a diagram showing another positional relationship between the paper P and the contact member 700).

In other words, when the rotation angle of the contact member 700 is set based on the information about the paper P as described above, the contact member 700 and the paper P are arranged in the state shown in FIG.
In addition, if the rotation angle of the contact member 700 is set based on the information about the paper P and the rotation angle from a predetermined reference (not shown) is set, the contact member 700 and the paper P can be obtained, for example, FIG. It is arranged as shown in.

More specifically, in the present embodiment, when the information about the paper P supported by the support portion 300 is the information indicating that the paper P is a specific paper P, the tip portion 700X of the contact member 700 is further lowered. The rotation angle of the contact member 700 is set so as to be arranged.
In this case, the contact member 700 is arranged in the state shown in FIG. More specifically, the contact member 700 is arranged on the side of the specific paper P.
In this case, contact between the contact member 700 and the specific paper P is ensured.

Here, in the present embodiment, as described above, the case where the position of the contact member 700 in the vertical direction is changed based on the information about the paper P has been described. In other words, the case where the rotation angle of the contact member 700 is set based on the information about the paper P has been described.
By the way, not limited to this, the position of the contact member 700 in the vertical direction may be changed based on the information about the position of the support portion 300 in the vertical direction. In other words, the rotation angle of the contact member 700 may be set based on the information about the position of the support portion 300 in the vertical direction.

In this case, when the CPU 111 acquires information indicating that the support portion 300 is located below the normal position (predetermined position), the CPU 111 changes the position of the contact member 700 in the vertical direction and changes the position of the contact member 700. The contact member 700 is arranged so that the tip portion 700X of the 700 is arranged lower.
In other words, when the CPU 111 acquires information indicating that the support portion 300 is located below the normal position, the CPU 111 sets a new rotation angle for the rotation angle of the contact member 700, and the tip portion of the contact member 700. The 700X is placed further down.

In the example shown in FIG. 16, the state in which the paper P is pressed from both sides by using the two contact members 700 is shown. In other words, as described with reference to FIG. 8, the state in which the paper P is pressed from both sides by using the two contact members 700 is shown.
However, not limited to this, also in the loading mode with the offset shown in FIG. 9, the position of the contact member 700 in the vertical direction is similarly based on the information about the paper P and the position of the support portion 300. May be set.
In other words, even in the offset loading mode shown in FIG. 9, the rotation angle of the contact member 700 may be set based on the information about the paper P and the information about the position of the support portion 300.
In the above, when the amount of lowering of the support portion 300 is increased, the position of the paper P resting on the support portion 300 is lowered, making it difficult for the contact member 700 to come into contact with the paper P, or the contact member 700 to come into contact with the paper P. An example was shown in which the discontinuity is suppressed by setting the rotation angle of the contact member 700, but the width is widened as in the wide portion 785A, the amount of descent is increased, and the contact portion is absorbed. Alternatively, the amount of increasing the amount of descent may be suppressed so that the width of the wide portion 785A is sufficiently contained in the first place.
In addition, the quality of the paper, which requires a large amount of force to align the paper by the contact member, is such that the area in contact with the contact member is constantly increased, or the portion of the contact member that is supported by the coil spring. The amount of lowering of the support portion 300 may be controlled so that the support portion 300 comes into contact with the close portion. Specific examples of the paper quality that requires a large amount of force to align the paper by the contact member include thick paper and high-density paper.
Further, depending on the paper quality, the paper quality A, which requires a relatively small force for aligning the paper, is controlled to reduce the number of tray movements by setting the rotation angle in addition to the tray movement, and the paper quality A is smaller than the paper quality A. The paper quality B, which requires a relatively small force to align the paper quality B, may be moved only to the tray.
