BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a media processing device for accumulating conveyed media, and more particularly to a media processing device built into an automatic transaction device installed in a financial institution such as a bank, and at the same time a media. The present invention relates to a medium processing device for separating and feeding out or storing a medium.

[0002]

2. Description of the Related Art Conventionally, as a medium processing device, for example, in a banknote stacking device incorporated in a banknote depositing / dispensing device of an automatic transaction device, a banknote is conveyed to a stacking part by a roller and provided at an end of the stacking part. The bills collected by the stopper were collected by receiving them. The stacking section is provided with side guides on both sides of the banknote in the longitudinal direction,
With this side guide, the conveyed bills are brought to the center of the stacking unit.

After the stacking of the banknotes, the banknotes are stored in the storage unit or fed again to the transport path. For this reason, the banknotes are placed on a stage that can be raised and lowered in the stacking unit, and when the banknotes are to be stored, the banknotes are pressed from above by a pressing member, and in that state the stage is lowered to the storage unit. When it is fed again to the transport path, the stage is raised until the bill is pressed against the feeding roller arranged at the upper part of the stacking unit, and when the bill is pressed, the feeding roller is rotated to move one sheet from the uppermost bill. I was trying to feed each one.

[0004]

Some banknotes stacked in the stacking section have curled edges in the longitudinal direction.
Some of the curled bills are stacked in contact with the side guides, as shown in FIG. In FIG. 12, the bill 1 is placed on the stage 2, and a side guide 62 is provided on the side portion of the stage 2. When the banknote 1 is pressed from above by a pressing member in this state, the end portion 1a of the banknote 1 enters the groove of the side guide 62 as shown by the dotted line. This groove is a groove for the pressing member to enter and move up and down. When the stage 1 is lowered for storage while the end 1a of the bill 1 is in the groove of the side guide 62, the bill 1 may be caught by the side guide 62 and cause a malfunction of the stage 2. Further, the end portion 1a of the bill 1 is the side guide 6
If you try to pay out banknote 1 while it is in the groove of 2,
In some cases, the end portion 1a of the bill 1 was caught by the side guide 62 and could not be fed out, or the bill 1 was skewed.

[0005]

In order to solve the above-mentioned problems, the present invention relates to a medium processing apparatus for accumulating conveyed mediums one by one on a stage, and a medium accumulating section on the end side of the stage. It has a protrusion guide part that protrudes to the side,
It is characterized in that a lower part of the projection guide portion is provided with a guide member having a shape approximated to a development locus of a curled end portion of the medium.

According to the present invention, when the end portions of the banknotes to be stacked are curled, the tip of the curled portion comes into contact with the projection guide portion of the guide member. Since the lower portion of the protrusion guide portion is shaped to approximate the development trajectory of the curled end portion of the medium in the longitudinal direction, when the curled portion of the bill is extended, the tip of the bill extends along the above shape. Therefore, the end of the bill does not enter the groove of the side guide.

Is installed.

Next, a bill stacking operation in this embodiment will be described. When the banknotes 1 are stacked in the stacking unit 5, first, the tension roller 22 and the tongue piece 23 are lifted until the tension roller 22 comes into pressure contact with the feed roller unit 19, as shown in FIG. In this state, the shaft 15 is rotated in the direction of arrow a shown in FIG. 1 by a motor (not shown). The idle gears 13 and 14 are rotated by the rotation of the shaft 15.
The shaft 10 also rotates in the same direction via, and the picker rollers 8 and 9 also rotate in the same direction.

The banknote 1 fed from a not-shown transport path has a feed roller portion 19 and a tension roller 22.
Between the roller portion 20 and the reverse roller 2
It passes through the space between 1 and is fed to the stacking unit 5. The bill 1 that has passed through the reverse roller 21 has a bill stopper 6,
7 is collided, the conveyance is stopped, and the tongue piece 23 knocks the sheet downward to stack the sheets on the stacking section 5.

As shown in FIG. 10, the conveyance path of the banknotes 1 when the banknotes 1 are sent to the stacking section 5 is located at a position where the banknotes 1 pass through the inclined portion 34 of the support guide 4 of the side guide 3 in the height direction. There is. FIG. 10 is an explanatory diagram showing the positional relationship between the banknote transport path and the side guides. Therefore, when the longitudinal end portion of the banknote 1 hits the inclined portion 34 of the support guide 4, the banknote 1 is brought closer to the central portion side of the stacking section 5 in the banknote longitudinal direction. When the edge 1a of the banknote 1 is curled, the side edge of the banknote 1 abuts against the upper part of the inclined portion 34 of the support guide 33, so that the banknote 1 is gathered further inward than the uncurled banknote 1 and is stacked. .

The conveyance path of the bill 1 is not always constant, and it may pass below the position where it passes through the inclined portion 34 of the support guide 4 in the height direction. That is, banknote 1
The end portion 1a of the side guide 4 may abut the sloped portion 33a of the side guide 4, but in this case, the sloped portion 3 of the side guide 4
Since 3a acts so as to move the banknotes 1 inward, the banknotes 1 are also moved inward and stacked in this case.

When the banknotes 1 are collected, the motor (not shown) is stopped, the shaft 15 is stopped, and all the roller parts are stopped. Then, the tension roller 22 and the tongue piece 23 descend to the original position (the position shown in FIG. 2).

FIG. 1 shows a state in which the banknotes 1 having curled edges 1a in the longitudinal direction are stacked on the stage 2 so as to be closest to the side guide 3a side. At this time, the end portion 1 a is in contact with the inclined portion 34 of the support guide 4. In this state, when the banknote 1 is pressed from above by the banknote pressing member 61 as shown in FIG. 11, the curled edge 1a of the banknote draws a locus (expansion locus) as indicated by a dotted arrow and becomes horizontal. It grows straight. However, at this time, the end portion 1a is the side guide 3
It does not enter the groove 31 of a and is deposited in a state of being extended inside the side guide 3a.

The accumulated banknotes 1 are then stored in a storage unit (not shown) located below the stage 2. Banknote 1
When storing the bills, the stage 2 and the bill holding member 61 are lowered together with the bill 1 held from above by the bill holding member 61. At this time, since the end 1a of the bill 1 does not enter the groove 31 of the side guide 3, the end 1a of the bill 1 does not get caught on the side guide 3 or other members when the stage 2 descends. The storage operation can be performed.

When the banknotes 1 stacked in the stacking section 5 are separated and fed out, the stage 2 on which the banknotes 1 are placed is moved to the banknote 1
Are raised until they are pressed against the picker rollers 8 and 9. In this case, if the end 1a of the uppermost banknote 1 is curled, the end 1a may be lifted from the horizontal state, but when it is extended horizontally, the side guide 3 will surely move. Since it is on the inner side, even if the picker rollers 8 and 9 are rotated in this state to start separating and feeding, the end portion 1a does not get caught in the side guide 3 or the like and cause a skew or the like.

In the above embodiment, the stage 2 is moved up and down.
An example in which the support guide 4 is provided so as to be retractable in order to retract from the banknote holding member or from the bill holding member has been shown, but if the stage 2 and the bill holding member do not come into contact with the support guide 4, or If there is no member that contacts the support guide 4, the support guide may be formed integrally with the side guide. In this case, the side guide and the support guide can be manufactured as one component, so that the effect of cost reduction can be expected. Alternatively, the support guide may be provided not on the side guide but on another member, for example, the side frame.

In the above embodiment, the bill stacking device built into the bill depositing / dispensing device has been described, but the present invention is a device for stacking a plurality of paper-like media, for example, another device such as a ticket issuing device. It is also applicable to.

In the above embodiment, the apparatus for conveying and accumulating the bills in the direction orthogonal to the longitudinal direction has been described as an example, but in the apparatus for conveying and accumulating the bills in the longitudinal direction of the medium, The present invention can be applied even when the ends are curled. Further, in an apparatus for transporting and accumulating in the longitudinal direction of the medium, the present invention can be applied even when the end portion of the medium in the lateral direction (direction orthogonal to the transport direction) is curled. In short, the present invention is applicable regardless of in which direction the medium is conveyed and whether the curled end of the medium is in the longitudinal direction or the lateral direction.

[0032]

As described above in detail, according to the present invention, the guide member is provided with the protrusion guide portion, and the lower portion of the protrusion guide portion is shaped so as to approximate the development locus of the curled end portion of the medium. Therefore, when the curled portion of the bill is extended, the tip of the bill extends along the above shape. As a result, the banknotes are stacked so that their ends are inside the guide member, so that malfunctions will not occur in the subsequent storage operation and separation / feeding.
