Abstract

PURPOSE:To efficiently perform the discriminating work by providing a specific foreign sheet detecting function to eliminate a need to prepare special discrimination reference data at each time of the discriminating work of sheets. CONSTITUTION:A vacuum pressure is caused to act on the inside of a suction shaft 5 to turn over and count banknotes 5 on a holder 1 one by one, and simultaneously, banknotes S are discriminated. When it is discriminated that a sheet is on the top of banknotes S loaded on the holder 1, detection data of this first sheet is stored as discrimination reference data, and it is discriminated whether foreign sheets are mixed in following banknotes or not based on this discrimination reference data. Thus, it is unnecessary to prepare special discrimination reference data at each time of discriminating work, and the discriminating work is performed without paying attention to the distinction between sheets and banknotes.

Description

Detailed Description of the Invention "Industrial Field of Application" The present invention relates to banknote counting machines, and in particular, to countering banknotes such as banknotes such as 1,000, 5,000, and 10,000 banknotes, or paper sheet bundles such as lottery tickets. The ends of the banknotes are turned over one by one by a suction shaft on a rotary cylinder, and the banknotes are counted, and the denominations, etc. of the banknote bundles are determined to detect whether banknotes of different denominations are mixed in the banknote bundle. The present invention also relates to a discrimination device for a banknote counting machine that is capable of detecting whether a bundle of paper sheets is made of the same paper sheets or not.

``Prior art'' Conventionally, this type of banknote counting machine was developed in Japanese Patent Application Laid-Open No. 63271.
The one shown in Japanese Patent No. 687 is known.

That is, the end portion of a banknote bundle is turned over one by one by a suction shaft on a rotary cylinder and counted, and each time the banknote is turned over, the detection data of the banknote read by an area sensor is stored in advance. The denomination, etc. is determined by comparing it with the discrimination standard data that was used, and thereby it is possible to detect whether different denominations of banknotes are mixed in the banknote bundle. If it is impossible to determine (
If the detection data of the first bill does not match the pre-stored discrimination standard data, the holder will
It was determined that paper sheets other than banknotes were loaded and was controlled to perform only normal counting operations.

``Problem to be solved by the invention'' However, in financial institutions where this type of banknote counting machine is installed, it is not possible to count specific types of paper sheets, such as lottery tickets, in addition to banknotes. Therefore, when counting these paper sheets, it is a problem that different types of paper sheets are mixed in.

Then, in order to detect the different types of paper sheets, the detection data of the read paper sheets may be compared with pre-stored discrimination reference data, similar to the detection of different denominations of banknotes. However, since there are an unspecified number of types of paper sheets, it is not possible to prepare a large number of discrimination criteria data one by one in advance, and it is practically impossible to distinguish and eliminate such different types of paper sheets. It was impossible.

The present invention has been made in view of the above circumstances, and includes:
Without preparing in advance discrimination standard data for paper sheets other than banknotes,
Regarding paper sheets other than banknotes, it is possible to determine whether or not different types of paper sheets are mixed in, and the detection angle of the area sensor for obtaining detection data is the 1st sheet and N sheets of the count value. It is an object of the present invention to provide a discrimination device for a banknote counting machine that can eliminate the effects of noticeable changes.

[Means for Solving the Problem] In order to achieve the above object, in the first invention, the ends of the banknotes loaded in the holder are turned over one by one while being attracted to the suction shaft, and the banknotes are turned over one by one. In a banknote counting machine that detects whether or not banknotes of different denominations are mixed in banknotes based on detection data that is sequentially output in response to turning over of the banknotes, the first banknote Discrimination means for discriminating whether the first sheet is a banknote, banknote, or paper leaf, and when the first sheet is determined to be a paper sheet, the detection data of the first sheet is used as determination reference data. the paper sheet data storage means for storing the paper sheet data as a banknote data storage means, the discriminating means compares the discrimination reference data stored in the banknote data storage means with the detection data for the second and subsequent sheets, A different kind of paper sheet detection function is provided to detect whether or not different kinds of paper sheets are mixed in after the first one.

In the second invention, the determination means determines that the detection data of the Nth paper sheet (where N≧2) matches the determination reference data stored in the paper sheet data storage means. A storage update control means is provided for outputting an update signal for updating and storing the detected data in the paper sheet data storage means as new discrimination reference data.

"Operation" According to the first invention, when the first bill among the bills loaded in the holder is determined to be "paper sheets", the first bill Detection data of paper sheets is stored as discrimination standard data, and furthermore, based on this discrimination standard data, it is compared and determined whether or not a different type of paper sheet is mixed in from the second sheet onward. When discriminating paper sheets, there is no need to prepare special discrimination standard data each time the discrimination work is performed, and thereby the discrimination work can be performed without being conscious of whether it is a banknote or a paper sheet.

According to the second invention, the detection data of the second paper sheet and the discrimination reference data, which is the detection data of the first paper sheet stored in the paper sheet data storage means, are different from each other. When the discrimination means determines that they match, the detection data of the second paper sheet is updated and stored in the paper sheet data storage means as new discrimination reference data, and thereafter, in the same manner,
The detection data of the Nth sheet is compared with the detection data of the (N-1)th sheet, and if it is determined that they match, the next (N+1)th sheet is detected. The information can be updated and stored in the paper sheet data storage means as new discrimination reference data for comparison and discrimination with the paper sheet detection data.

The light receiver 24 includes an area sensor 25 that generates an electric signal according to the pattern on the surface of the banknotes, and a condenser lens 26 that collects reflected light from the banknotes sb onto the area sensor 25. There is. The area sensor 25 is a two-dimensional sensor in which a large number of line-shaped image sensors are arranged in a direction perpendicular to the line, and the bills are turned over one by one by the suction shafts 5. Each time a banknote is taken, it scans area E, converts the amount of reflected light at a specific position (line or coordinate) in area E into an electrical signal, and outputs a signal with a waveform corresponding to the surface pattern of the banknote. It has become. The detection data as the surface pattern of the banknotes read by the area sensor 25 is stored in a ROM (banknote data storage means) when the banknotes are banknotes such as 1,000-note, 10,000-note, etc. Compared with the discrimination standard data, banknotes sb

Note that the different denomination banknotes refer to the second and subsequent banknotes that do not match the denomination of the first banknote when the first banknote to be counted and determined is a banknote. (including cases that are not banknotes), and the above-mentioned different types of paper sheets refers to the first sheet of banknotes to be counted and determined, for example, when the first sheet of banknotes is a paper sheet such as a lottery ticket.

First, the detection means 100, the detection data storage means 101, the discrimination means 102, the selection means 103, and the banknote data storage means 104 will be explained separately for items (i) to (iii). (i) The detection means 100 is , irradiates light onto the surface of the end of the banknotes that are about to be attracted by the suction shafts 5, 5, etc., detects the reflected light by the area sensor 25, and collects detection data (i.e., the surface pattern of the banknotes). b) is output.

(ii) The detection data storage means 101 is the detection means 1

At the same time, outputting the detected data (a) to the determining means 102; (d) temporarily storing the detected data (a); and storing the detected data (a) on condition that an update signal RN, which will be described later, is input The detected data (a) is stored in paper sheet data storage means 1.
06 (described later). Thereafter, every time the update signal RN is input, the stored detection data (a) is output to the sheet data storage means 106.

(iii) The determining means 102 counts the removed banknotes and determines whether the banknote is the first banknote or paper sheet. If the first sheet is a banknote, then it is determined whether a different denomination is mixed in the second or subsequent banknotes.The first sheet is a paper sheet. It has the function of determining whether or not a different type of paper sheet is mixed in after the second banknote when the banknote is of the same type as the banknote. When the detection data (a) is input, this detection data (a) is stored in the banknote data storage means 104 via the selection means 103 (described later).
It is compared with all the discrimination reference data (b) taken in from the detection data (b), and it is determined whether any of these discrimination reference data (b) matches the detection data (a). Then, if some of these discrimination standard data (b) match the detection data (a), the first banknote is
If there is no matching banknote, the first banknote is determined to be a "paper leaf."

Note that the banknote data storage means 104 stores in advance discrimination standard data indicating surface patterns of front and back sides of denominations such as 1000-note, 5000-note, 10000-note, etc. The first detection data (
When (a) is input, all the discrimination reference data (b) are selected by the selection means 103 and supplied to the discrimination means 102.

(iv) When it is determined that the first banknote is a "paper sheet" such as a lottery ticket, an abnormality signal NGI is output to the timing control means 107 (described later). Further, if some of the discrimination standard data (b) matches the detection data (a) and the first banknote is therefore determined to be a "banknote", the timing control means 107 (
(described later), and outputs a denomination signal (c) indicating the denomination of the first banknote to the selection means 103.

Note that when the selection means 103 determines that the first bill is a "banknote" and further attempts to determine the second and subsequent bills based on the determination result, the above-mentioned denomination signal ( Based on c), the first
The discriminating means 102 selects discrimination standard data regarding the front and back sides of the denomination of the banknote, and
We are trying to supply it to

(3) When the first banknote loaded in the holder 1 is determined to be a "banknote", the selection means 103 supplies the detection data (a) sequentially supplied from the second banknote onwards. Discrimination standard data for the obverse and reverse sides of specific denominations (
b)゛ As a result, if one of these discrimination reference data (b)° matches the detection data (a), it continues to output a confirmation signal GD1 to the timing control means 1゛7. , and when there is a mismatch (that is, when the banknotes are of different denominations), an abnormality signal NG2 is output.

(4) When the first bill loaded in the holder 1 is determined to be a "paper leaf", the second and subsequent bills are determined based on the first paper bill. The paper sheets are sequentially compared and it is determined whether or not they match (details will be explained below).

Hereinafter, the configuration related to (4) control of the discriminating means 102,
That is, the configurations of the memory update control means 105, paper sheet data storage means 106, and timing control means 107 and their signal flows will be explained.

When determining the first banknote, the memory update control means 105 sets the first condition to be that an abnormal signal NGI indicating that the first banknote is a "paper sheet" is output. , and confirmation indicating that the Nth sheet matches the (N-1)th sheet when determining the Nth sheet (however, N≧2). The second signal indicates that the signal GD2 is output.
Based on the trigger signal (d) output from the timing control means 107 (see explanation of the timing control means 107 described later) under the conditions of The update signal RN is output after each paper sheet is discriminated, and the following controls (-) to (3) are performed. In other words, the trigger when the (-) abnormal signal NG1 is output is based on the signal (d),
Detection data storage means lot and paper sheet data storage means 1
The update signal RN is outputted to the paper sheet data storage means 106 to output the detection data (a) of the first sheet stored in the detection data storage means 101 to the sheet data storage means 106 and store it.

(d) A switching signal CG is output to the selection means 103 to stop the acquisition of the discrimination reference data (b) from the banknote data storage means 104, and each time paper sheets are counted,
The discrimination reference data (e) stored in the sheet data storage means 106 is outputted to the discrimination means 102.

Then, in the discriminating means 102, the second sheet detection data (a) is determined as the discriminating reference data (e) inputted from the sheet data storage means 106 via the selecting means 103.
(In this case, it is the detection data of the first sheet).

(3) Second detection data (a) and discrimination standard data (
Based on the trigger signal (d) when it is determined that the values match e) and the confirmation signal CD2 is output, an update signal RN is output to the detected data storage means 101 and the paper sheet data storage means 106, The detection data (a) of the second sheet stored in the detection data storage means 101 is outputted to the sheet data storage means 106 and stored therein.

To put this into perspective, as the paper sheet discrimination progresses, the discrimination standard data serving as the reference is sequentially updated and stored while the discrimination operation is performed. That is, the discrimination of the Nth image by the discriminator 102 is performed using the (N-1)th image detection data (A) as the discrimination reference take.

As a result of the comparative discrimination, the Nth sheet detected data (a) does not match the (N-1)th sheet discrimination standard data (e), and thus it is determined that the paper sheet is of a different type. In this case, an abnormality signal NG3 is output. Furthermore, if it is determined that the Nth piece of detection data (A) matches the (N-1)th piece of discrimination reference data (E), a confirmation signal GD2 is output that causes the counting discrimination to continue as is. .

Next, the timing control means 107 will be explained. (-) It outputs timing signals (H) to (H) to the detection means 100, the detected data storage means LO, and the discrimination means 102, respectively. This timing signal is output in synchronization with the detection of the actuating piece 14A by the magnetic sensor 14, that is, in response to the turning over of banknotes by the suction shafts 5, etc., and is output by the detection means 100. The surface pattern of the banknote is read by the area sensor 25, and the detected data (
A) is stored and outputted, and the detection data (A) and discrimination reference data (B) and (B) are provided to the discriminating means 102.
・Have students make comparisons and judgments with (e).

(d) The first condition is that the abnormal signal NGI indicating that the first banknote is a "paper sheet" is input from the discrimination means 102, and the Nth banknote (however, When determining paper sheets with N≧2), the Nth paper sheet is the (N-1)th sheet.
The memory update control means 105 sets the second condition that the confirmation signal GD2 indicating that the sheet matches the sheet corresponds to the second sheet.
The bird outputs a signal (d).

(3) On the condition that an abnormality signal NG2/3 indicating that a different denomination banknote or a different type of paper sheet is input from the second or subsequent banknotes is input from the discriminating means 102, the pump NG to stop the motor 12 and notify that an abnormality has occurred
Output a signal.

As explained above, according to the banknote counting machine shown in this embodiment, when the determining means 102 determines that the banknote is the first banknote or "banknote", the denomination signal (C) is sent. Then, the second and subsequent banknotes are discriminated based on the discrimination standard data (b) corresponding to the denomination of the first banknote, thereby determining whether a different denomination is mixed in the banknote. It is now possible to detect whether or not it is.

Further, when the first banknote is determined to be paper sheet j by the determination means 102, the determination means 102 outputs an abnormal signal N G 1, the timing control means 107 outputs a trigger signal (d), By outputting the update signal RN and the switching signal CG from the memory update control means 105, it is possible to determine whether the detection data storage means 101
The detection data (a) of the first sheet stored in the paper sheet data storage means 106 was stored as discrimination reference data (e).

■ When the detection data (a) of the second sheet is output from the detection means 100 and stored in the detection data storage means 101, this second sheet detection data (a) and the paper sheet data storage means 106 Discrimination standard data (e) stored in (first
The detection data (a) of the first sheet is outputted to the discriminating means 102.

As a result, the discrimination means 102 compares and discriminates the detection data of the second sheet (A) with the detection data of the first sheet (A) as discrimination reference data, and if they do not match, it is determined that the paper sheet is of a different type. If so, an abnormal signal NG3 was output.

Further, if the comparison results in a match, the paper sheet is recognized as the same type, and a confirmation signal GD2 is output, and the detected data storage means 1 outputs a confirmation signal GD2.
The detection data (A) of the second sheet stored in 01 was stored in the sheet data storage means 106 as new discrimination reference data (E).

■ Furthermore, the process of updating the discrimination standard data (e)
Since the determination is made every time the confirmation signal GD2 is continuously outputted from the determination means 102, the determination of the Nth sheet is performed using the detection data (a) of the (N-1)th sheet as determination reference data. As a result, the discrimination standard data is
The count is sequentially updated one by one for every 0.

As a result, the counting of banknotes progresses and the distance between the banknotes located in the uncounted area and the area sensor 25 changes, and the detection angle of the area sensor to obtain the detection data (A) changes between the 1st banknote and the It is possible to eliminate the influence of changes in

In addition, in the above embodiment, for the comparison and discrimination of the Nth sheet,
(N-1) Detection data of counted paper sheets (a)
is used as the discrimination reference data, but is not limited to this, for example, the area sensor 25 may be used so that the detection angle between the area sensor 25 and the surface of the banknote is always constant.
The orientation of the paper sheet is adjusted according to the count, and as a result, the detection data (a) of the first paper sheet can be detected without updating the discrimination reference data stored in the paper sheet data storage means 106. It is also possible to perform the process of discriminating different types of paper sheets by using only the above-described method. In addition, if the structure is not influenced by the detection angle of the banknote counting machine or the area sensor 25, the detection data of the first paper sheet (a)
It is also possible to perform the process of discriminating different types of paper sheets by using only the above-described method.

Furthermore, each means described in the claims of the present invention is
It does not necessarily indicate physical means, and these functions may be realized by software. For example, when the function of one means described in the claims is realized by two physical means, Alternatively, the present invention also covers a case where the functions of two means described in the claims are realized by one physical means.

"Effects of the Invention" As explained in detail above, according to the first invention, when distinguishing paper sheets, there is no need to prepare special discrimination standard data every time a discrimination operation is performed, and this makes it possible to The discrimination work can be performed without being conscious of whether it is a banknote or a paper sheet, and the discrimination work can be performed efficiently.

According to the second invention, the detection data of the (N-1)th sheet can be compared and discriminated using the Nth sheet detection data as its discrimination reference data, so that the detection data of the (N-1)th sheet can be compared and discriminated. It is possible to eliminate the influence of the detection angle of the area sensor changing between the first image and the Nth image.
