ことにある。Therefore, it is very convenient to combine the paper sheet dispensing means and use it in a paper sheet stacking and dispensing mechanism of an automatic cash handling device or the like. FIG. 5 shows a side sectional view of an example of a sheet stacking and feeding mechanism using a conventional stacking mechanism. However, in this type of mechanism, when switching from the sheet stacking operation to the feeding operation, it is necessary to raise the sheet group 1' in the storage section 2 by a moving mechanism and bring it into contact with the pickup roller 51, which is the feeding means. be. The rear end of the sheet group 1 that rises during this switching pushes up the endless belt 5, so the increased pressing force between the endless belt 5 and the sheet group 1 at this time causes the sheet group 1' to move as shown by the broken line in FIG. There is a problem that the pickup is pulled into the pickup and becomes an obstacle to the next feeding operation if the alignment position is uneven.To solve this problem, a pickup as described in the above-mentioned prior art Japanese Patent Application Laid-Open No. 59-45745 is proposed. A paper sheet stacking and feeding mechanism is provided with a contact means that can change the rotational position of the endless belt as the roller moves, and has a structure in which the rotational position of the endless belt is retracted by the contact means when paper sheets are fed out. be. However, this mechanism has the problem that since the fixing member comes into contact with the endless belt, the endless belt must have wear resistance to withstand this, making it difficult to extend the service life. The object of the present invention is to solve the above-mentioned drawbacks and realize a stacking and dispensing mechanism capable of stably stacking and dispensing paper sheets.

This can be achieved by creating a structure in which the protruding position of the endless belt is moved.

動作が安定する。When changing the sheet stacking operation to the feeding operation, the protruding position of the endless belt can be retracted by moving the position of the guide means, so that the rear ends of the sheets are not drawn into the endless belt and are aligned. Keep it in good condition and leave it as it is
Switching from operation to feeding operation is possible υ, and feeding operation is stabilized.

〔実施例〕
以下、本発明の一実施例を図面により説明する。(9) In the present invention, since the endless belt can be retracted without contacting the fixing member, unnecessary wear of the endless belt does not occur, and it is possible to switch from the stacking operation to the feeding operation without stopping the rotation of the endless belt. Therefore, there is no need to control the drive of the endless belt. [Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

く、順次安定した堆積動作が進行する。In the high-quality paper sheet stacking and feeding device configured as described above,
First, during the stacking operation, as shown in FIG.
At the same time, the link 29 is pulled to move the protrusion of the endless belt 5 toward the storage section 2. The paper sheet 1 is held between a rotating feed roller 3 and an opposing roller 4, and is pushed by an endless belt 5, which also rotates, and is sent to the storage section 2 while being deformed into a corrugated plate shape as shown in 1 in FIG. 9 is thrown in. By deforming the paper sheet 1 into a corrugated plate shape, even if there are folds, wrinkles, etc., the paper sheet 1 has high rigidity in the feeding direction and is stable without bending in the middle, so that it is stable in the order of Fig. 4 (α) → (hl). , the diameter of the hole that has come loose from the grip between the feed roller 3 and the opposing roller 4,
Furthermore, the endless belt 5 is fed until the leading end contacts the leading edge guide 21. At that time, the endless belt 5 is moved by the frictional force generated by the contact pressure with the sheet 1 as shown in FIG. 4(C).
As shown in Figure 4 (di), the side of the arrow α becomes the tension side, and the side of the arrow becomes the slack side, and the sheet rides on the rear end of the sheet 1, and as shown in Fig. 4 (di), the sheet 1 is knocked down onto the sheet group 1. As a result, the paper sheets 111- are stacked in good alignment on the paper sheet group 1', and the stacking operation progresses in a stable manner one after another without the subsequently fed filter paper sheets 1 colliding with each other.

As shown in the figure, the sheet group 1' is retracted from above, and the carrier 23 is moved upward to bring the sheet group 1 into pressure contact with the pickup roller 51. Next, the pickup roller 51,
When the feed roller 32 is rotated to the right in the figure by a power source N (not shown), the sheet group 1' is sent out at regular intervals, and the feed roller 52 rotates like the pickup roller 51 and the gate roller 55 does not rotate. The sheets are separated one by one and fed to the next stage.

The endless belt 5 can be stacked stably and well-aligned, and when switching between the stacking operation and the feeding operation, the endless belt 5 is
Since the retracting movement can be performed by a movement of 6 hours, the endless belt 5 is not pushed up when the carrier 25 rises, and the sheet group 1 is not drawn into the endless belt 5 and becomes misaligned. is maintained and stable, allowing for the next operation. In addition, the operation can be switched even while the endless belt 5 is rotating, so there is no need to control the drive of the endless belt 5, and since the endless belt 5 does not come into contact with fixed objects when it is retracted, there is no wear on the endless belt 5. .
