Abstract

PURPOSE:To keep height of a paper sheets receiving space constant all the time, by installing a paper sheets keep plate, which is slidden according to a stacking quantity of paper sheets taken in on the stacking block in consecutive order, in a temporary store part. CONSTITUTION:When bills are projected, these bills are fed to a temporary store part 1 passing through a classifying part C. The number of receipt sheets are counted by this classifying part C, and stored in a memory 27. And, since these bills (A) are stacked on a stacking block 2 in front of a bill keep plate 3 in consecutive order, this bill keep plate 3 moves backward according to the stacked quantity, and the moving quantity is readout of a magnetic scale 11 by a magnetic sensor 10. This reading value is also stored in the memory 27. A main central processing unit 26 calculates apparent thickness of a sheet of the bill from information of two kinds aforesaid. When these bills (A) are fed to a final store part 12 from the temporary store part 1, a driving signal equivalent to the said apparent width is fed to a pulse motor each time these bills (A) passes through the classifying part C in the process, whereby a paper supporting plate 14 inside a cartridge 13 is lowered as far as a portion for a sheet of the bill, and this operation is repeated.

Description

Detailed Description of the Invention (a) Field of the Invention The present invention relates to a paper Ti type processing device for processing deposited and withdrawn banknotes, such as an automatic teller machine used in banking business, and particularly to a paper Ti type processing device for processing deposited and withdrawn banknotes. Concerning the accumulation control method for stable storage.

(b) Day before the invention Conventionally, a structure as shown in FIG. 4 has been used as the automatic deposit payment method of the above-mentioned example. In this process, the deposited banknotes inserted into the input slot are passed through the depositing route shown by the thick line B, passed through the banknote discrimination part C, and accumulated in the temporary storage part, and then fed out and collected as shown by the broken line E. The banknotes are sent through the route to the final store section F, and the banknotes are separated into car 1-ridge sections f, f', f' according to the denominations discriminated by the banknote discriminating section C.
When there is a withdrawal command thereafter, the banknotes are discharged from the final storage section F to the input slot A according to the withdrawal amount. In addition, in order to stably receive banknotes stacked flat in G and L final store sections F in this type of automatic teller machine, it is necessary to secure a banknote receiving space in each cartridge section, so the number of banknotes to be deposited is The height of the banknote receiving and supporting plate G in the department is controlled.

However, the stacking thickness per sheet varies depending on the quality and degree of deformation of the deposited banknotes, and there are many types of paper sheets that handle paper sheets other than banknotes and have uneven paper thickness. For the items we handle, it simply depends on the number of bills etc. that are inserted.
If the banknote receiving space in the cartridge section is controlled, the height of the banknote receiving space gradually becomes distorted, and stable banknote reception becomes impossible.

For example, when the bill receiving/supporting plate is lowered in accordance with the number of bills collected, the bill receiving space becomes larger if the bill is a new bill, and becomes smaller if the bill is an old bill with many wrinkles.

(c) Purpose of the Invention This invention does not read the number of paper sheets input, but calculates the apparent thickness of each paper sheet in the temporary storage section, and based on this calculates the height of the paper sheet receiving space. It is an object of the present invention to provide a paper sheet accumulation control method for a paper sheet processing device, in which the height is always kept constant by controlling the height.

(D) Summary of the Invention This invention provides a paper sheet presser plate in a temporary storage section that slides in accordance with the accumulation T of paper sheets sequentially carried onto the stacking table, and this paper sheet presser plate. A paper sheet accumulation control method for a paper sheet processing apparatus that detects the amount of movement of the paper sheet receiving space in a final storage section and keeps the height of the sheet receiving space constant.

(E) Effects of the Invention According to the present invention, the paper sheet pressing plate moves according to the accumulated amount of paper sheets sequentially carried into the temporary storage section! Since the paper sheet acceptance height of the final storage section is derived from lIm, the above-mentioned movement R will change depending on the thickness of the paper sheets even if the number of sheets is the same, and the paper sheets that are controlled based on the amount of movement will change depending on the thickness of the paper sheets. The height of the paper sheet receiving space can be kept constant, contributing to stable collection of paper sheets.

(Example of the invention) An embodiment of the present invention will be described in detail based on the drawings.

The drawings show an embodiment in which the present invention is applied to an automatic teller machine. FIG. A sliding bill pressing plate 3 is provided. At the front end of the stacking table 2, a carry-in guide row 55 with a pressure roller 4 is provided at the top, and a feed-out guide roller 7 with a pressure roller 6 is provided at the bottom. The banknotes A are carried in and stacked on the stacking table 2 on the front side, and the stacked banknotes A are fed out one by one from the stacking table 2 by the feeding guide roller 7.

The banknote holding plate 3 has a tension spring 9 interposed between its base frame 3a and a fixed frame 8 below the stacking table 2, so that the banknote holding plate 3 is always pulled and biased toward the front end of the stacking table 2. Ru.

Further, a magnetic sensor 10 is attached to the above-mentioned base frame 3a, and a magnetic scale 11 is arranged parallel to the stacking table 2 in correspondence with the magnetic sensor 10, so that when the banknote holding plate 3 moves, The amount of movement is detected by a magnetic scale 11.

FIG. 2 shows the final store section 12, and its cartridge 1
3, a banknote banknote 14 is installed to be moved up and down by the force of a pulse motor 15 (1 shown in FIG. 3). Further, at the entrance of the cartridge 13, a carry-in guide roller 17 with a pressure roller 16 and a feed-out guide roller 19 with a pressure roller 18 are provided.

Then, the carried banknotes are dropped onto the banknote receiving support plate 14 and stacked one on top of the other, and a predetermined banknote receiving space 20 is formed between the stacked layer and the cartridge entrance.

Figure 3 is a block diagram of the control system, and the discrimination section C shown in Figure 4.
There is a banknote identification sensor 21 and an I10 interface 22.
, a CPU 23, and a transmission interface 24 are provided. Other main CPU 26 , memory 27 , I10 interface 28 , magnetic sensor 10 , and pulse motor 15 are connected to discrimination section C via transmission interface 25 .

Now, when a banknote is inserted, the banknote passes through the validation section C and is fed into the temporary storage section 1. The number of deposited coins is counted by the discrimination section C and stored in the memory 27. Moreover, since the banknotes A are sequentially accumulated on the stacking table 2 in front of the banknote presser plate 3, the banknote presser plate 3 moves backward according to the amount of accumulation, and the amount of movement is measured by the magnetic sensor 10/+(1
Read from Qi scale 11. This reading G is also memory 27
is memorized. The main CPU 26 calculates the apparent thickness of one banknote from the above-mentioned two types of information stored in the memory 27 based on the pressing plate retraction amount/the number of stacked banknotes.

Therefore, even if the number of stacked bills is the same, if the thickness of each banknote differs, the amount of movement of the suppression plate will change in magnitude, and of course the apparent thickness of a single banknote will also change.

On the other hand, in the final store section 12, the height of the banknote receiving/supporting plate 14 is initially adjusted by the pulse motor 15, and a constant height of the banknote receiving space is set.

Next, when the banknote A is sent out from the primary store section 1 toward the final store section 12, a drive signal corresponding to the above-mentioned apparent width is sent to the pulse motor 15 every time the banknote A passes through the discrimination section C in the process. When the banknote receiving and supporting plate 14 in the cartridge 13 is lowered by one banknote, and this is repeated, for example, if the number of banknotes reaching the final storage section 12 is three, the banknote support plate 14 in the cartridge 13 is lowered by one banknote.
The banknotes A are dropped one after another and accumulated on the banknote support plate 14 after reaching the final storage section 12.

In this way, the present invention determines the apparent width of a banknote and uses this as the downward movement of a single banknote, so it is possible to detect a falling banknote without being affected by variations in the width of the banknote. It can be kept constant, and there is no need to reset the descent level of each bill receiving/supporting plate each time the type of paper sheet to be used is changed.

Note that although banknotes have been described in the above-mentioned embodiments, the paper sheets according to the present invention are not limited to the above-mentioned embodiments.
