This paper sheet counting machine counts paper sheets (paper bills or paper sheets such as certificates) loaded in a holder by sucking them one by one with a suction shaft of a rotating cylinder and turning them. The light reflected on the surface of the sheet is read by the image sensor, and the image data read by the image sensor is compared with all the reference patterns stored in advance to discriminate the sheet. It is the one. Further, in this paper sheet counter, the image data of the first paper sheet is compared with all the reference patterns stored in advance to determine the type of the paper sheet, and 2 based on the discrimination result of the first sheet
It is determined whether or not the paper sheets after the first sheet are the same as those of the first sheet.

[0003]

By the way, in the paper sheet counter configured as described above, the reference pattern for discriminating the first paper sheet is, for example, Japanese banknote 3 denominations (10,000 notes, 5 notes). Since it is limited to one subject such as 1,000 notes, 1,000 notes, etc., when counting paper sheets other than Japanese banknotes, we have newly developed a dedicated paper sheet counter corresponding to this. There was a problem that it had to be. Further, in the above paper sheet counting machine, when the number of reference patterns is increased in order to count and discriminate other paper sheets other than Japanese banknotes, the reference pattern and the first paper sheet are It takes a lot of time to compare with the image data, and as a result, a high-speed processing device is required, which is expensive.

The present invention has been made in view of the above circumstances, and is a paper sheet counting machine for counting and distinguishing various foreign banknotes, various certificate documents, paper sheets of each subject such as slips at high speed. For the purpose of providing.

[0005]

In order to achieve the above object, according to the first aspect of the invention, paper sheets such as banknotes loaded in a holder are adsorbed one by one by a suction shaft of a rotating cylinder and counted while being turned over.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A paper sheet counter according to the present invention will be described below with reference to FIG. In this paper sheet counting machine, the paper sheets (paper bills or paper sheets such as certificates) loaded in the holder are adsorbed one by one by the suction shaft of the rotary cylinder and are counted while turning, As described in "Prior Art", the structure of the portion for reading the reflected light of the light rays radiated on the surface of the leaves with the image sensor is disclosed in JP-A-3-134.
Since it is already known in Japanese Patent Publication No. 792, detailed description will be omitted.

In FIG. 1, reference numeral 1 is a reference pattern storage means, reference numeral 2 is a subject selection switch, reference numeral 3 is a subject selection means, reference numeral 4 is image data output means, reference numeral 5 is a comparison / determination means, and reference numeral 6 is one sheet. It is an eye determination result storage means.

As shown in detail in FIG. 1, the reference pattern storage means 1 is classified into a Japanese banknote item 1, a certificate item 2, and a slip item 3, and item 1 for 10,000 yen, Sheet data for Japanese banknotes for 5,000 yen and 1,000 yen, sheet data for certificates such as certificate A and certificate B in subject 2, and sheet data for slips A to D in subject 3 are stored. Has been done. Also,
The above-mentioned sheet data for 10,000 yen, 5,000 yen, and 1,000 yen, each sheet data for the certificate A and the certificate B, and each sheet data for the slips A to D are sheets (in an accumulated state). Has four reference patterns, each corresponding to the direction in which is loaded into the holder. For example, as the sheet data for 10,000 yen of the subject 1, four reference patterns such as the right side of the front surface, the left side of the front surface, the right side of the back surface, and the left side of the back surface are stored according to the direction in which the paper sheets are loaded into the holder. ing. Less than,
The sheet data for 5,000 yen, the sheet data for 1,000 yen, the sheet data for certificates A and B, and the sheet data for slips A to D are also oriented in the direction in which the sheets are loaded into the holder. Correspondingly, four reference patterns such as the front surface right side, the front surface left side, the back surface right side, and the back surface left side are stored.

The subject selection switch 2 is operated by the operator to select one of the subjects 1 to 3 classified in the reference pattern storage means 1. The subject selecting means 3 is based on the subject selected by the subject selecting switch 2, and the paper sheet data (10,000 yen paper leaf data, 5,000 yen paper leaf data, 1,000 yen paper leaf) stored in the reference pattern storage means 1 is selected. Data, certificate A paper sheet data, certificate B paper sheet data, slip A paper sheet data, slip B paper sheet data, slip C paper sheet data, slip D paper sheet data). For example, when the subject 1 is selected by the subject selection switch 1, the subject selecting means 3 causes the 10,000 yen paper leaf data, the 5,000 yen paper leaf data,
A total of 12 reference patterns, which are 1,000-yen sheet leaf data, are selected, and these 12 reference patterns are supplied to the comparison and determination means 5. In the same way, select subject 2 with subject selection switch 1
If is selected, the subject selection means 3 selects a total of 8 reference patterns which are the certificate A paper sheet data and the certificate B paper sheet data, and supplies these 8 reference patterns to the comparison determination means 5. In addition, subject 3 by the subject selection switch 1
If is selected, the course selection means 3 causes the slip A paper sheet data, the slip B paper sheet data, the slip C paper sheet data,
A total of 16 reference patterns which are the slip D paper leaf data are selected, and these 16 reference patterns are supplied to the comparison / determination means 5.

The image data output means 4 corresponds to the above-mentioned image sensor, and outputs one image data for each sheet every time the sheet is turned off by the suction shaft. The comparison / determination means 5 outputs the reference pattern for the subject selected from the reference pattern storage means 1 by the subject selection means 3 and the image data output from the image data output means 4 each time the paper sheet is turned off. The comparison is performed sequentially, and it is determined whether or not each sheet is in agreement. Further, the determination result for the first sheet determined by the comparison determination unit 5 is output to the first sheet determination result storage unit 6 and stored therein. In 5, the determination results for the first sheet and the determination results for the second and subsequent sheets stored in the first sheet determination result storage unit 6 are sequentially compared, and the comparison results are obtained. Based on this, it is determined whether or not the second and subsequent sheets are not aligned with the first sheet.

The comparison / determination means 5 can determine whether the types of paper sheets are uneven, the front and back are uneven, or the right and left are uneven, and the image data output from the image data output means 4 is stored in the reference pattern storage means 1. It is also possible to determine that a different type of ticket has been detected when it does not match all the reference patterns of the subject being taught. That is, in the comparison / determination means 5, (1) determination of different types of paper sheets for all paper sheets, (2) non-uniformity of types of paper sheets for second and subsequent paper sheets, non-uniformity of front and back sides, left and right It is possible to judge the irregularity. In addition, the determination of the type (2) of non-uniformity, non-uniformity of front and back, and non-uniformity of right and left in the comparison determination means 5 may be selectively performed according to an operator's instruction.

It should be noted that three types of subjects such as subject 1, subject 2, and subject 3 are set in the reference pattern storage means 1, and each subject is made to store 2 to 4 types of paper sheet data. , Number, content of subject, content of paper sheet data can be set arbitrarily. For example, "foreign banknotes such as dollars", "travelers'checks","lotterytickets","booktickets"
Classes such as "ticket" and "gift certificate" are stored as standard pattern storage means 1
Alternatively, these subjects may be arbitrarily selected by the subject selection switch 2 and the subject selection means 3. Also,
When registering image data relating to paper sheets such as slips with no printing on the back side in the reference pattern storage means 1, four types of reference patterns such as the front right side, the front left side, the back right side, and the back left side as shown in FIG. , The right side of the surface and the left side of the surface 2
It may be a reference pattern of a type.

As described above, according to the paper sheet counter shown in this embodiment, the reference stored in the reference pattern storage means 1 is selected in the subject selection means 3 based on the subject selected by the subject selection switch 2. A pattern is selected for each subject, and the comparison determination means 5 compares the reference pattern selected by the subject selection means 3 with the image data read from the image data output means 4 to determine whether they match or not. To do. That is, in the paper sheet counting machine shown in this embodiment, the reference pattern storage means 1 stores reference patterns corresponding to subjects such as Japanese banknotes, certificates and slips for each subject, and these reference patterns are stored for each subject. Can be arbitrarily and collectively selected, which brings about an effect of efficiently counting and discriminating paper sheets for each item such as various foreign banknotes, various certificates and slips. Further, this paper sheet counter does not compare the image data output from the image data output means 4 with all the reference patterns stored in the reference pattern storage means 1, but selects them by the item selection switch 2. Since it is to compare with the reference pattern for each subject, the processing time for comparison can be shortened as a result, the efficiency of the discrimination work can be improved, and the processing device for processing the data at high speed is also available. It becomes unnecessary and the price can be low.

Further, in the present embodiment, the comparing and judging means 5 discriminates a different type of ticket depending on whether or not the image data of the image data output means 4 (image sensor) matches the reference pattern of the reference pattern storage means 1. In addition, it is possible to determine the type, front / back, and left / right misalignment of the second and subsequent sheets based on the direction of the first sheet stored in the first sheet type / direction storage unit 6. However, if it is determined that different types of tickets and misalignment are determined, the following processes (1) to (4) may be performed. (1) As shown in Japanese Patent Laid-Open No. 64-76389, when a different type of ticket or misalignment is discriminated, the separator is operated to separate the counted paper sheets from the uncounted paper sheets in the holder. At the same time, the suction shaft and the rotary cylinder are stopped so that the different types of tickets and the irregular paper sheets are positioned between the plurality of suction shafts. It may be arranged between the counting paper sheets and the counted paper sheets which have already been turned over by the suction shaft. Further, when the operator judges that there is no abnormality in the heterogeneous paper sheets and the non-uniform paper sheets positioned between the suction shafts, for example, by visual inspection, the uncounted paper sheets may be counted again according to the instruction of the operator. good.

(2) As shown in Japanese Patent Application Laid-Open No. 1-116895, when different types of bills and misalignment are discriminated, the separator is operated to separate the counted sheets and the uncounted sheets in the holder. The suction shaft and the rotary cylinder are stopped so that the different types of tickets and the irregular sheets are positioned between the plurality of suction shafts, whereby the different types of sheets and the irregular sheets are located on the holder side. The sheet is placed between the uncounted paper sheets and the counted paper sheets that have already been turned over by the suction shaft, and after this, the separator is released, and then the paper sheet placed between the suction shafts. Alternatively, the class may be returned to the holder side, and the suction shaft and the rotary cylinder may be normally operated to count and discriminate the different types of sheets and the non-uniform sheets.

(3) As shown in Japanese Patent Laid-Open No. 22786/1990, when a different type of ticket or misalignment is discriminated,
In order to position uneven paper sheets between multiple suction axes,
The suction shaft and the rotary cylinder are stopped, so that
The misaligned sheets may be located between the uncounted sheets on the holder side and the counted sheets that have already been turned over by the suction shaft. Further, when the operator judges that there is no abnormality in the heterogeneous paper sheets and the non-uniform paper sheets positioned between the suction shafts, for example, by visual inspection, the uncounted paper sheets may be counted again according to the instruction of the operator. good.

(4) As disclosed in Japanese Patent Laid-Open No. 3-218592, when different types of bills and irregularity are discriminated, the different types of bills and irregularity are detected based on the detection value of the pressure sensor for detecting the pressure in the suction shaft. The suction shaft and the rotary cylinder are stopped so that the paper sheets are positioned between the plurality of suction shafts, whereby the different kinds of sheets and the uneven sheets are already sucked with the uncounted paper sheets on the holder side. It may be positioned between the counted paper sheets and the finished turning-off by the shaft. Further, when the operator judges that there is no abnormality in the heterogeneous paper sheets and the non-uniform paper sheets positioned between the suction shafts, for example, by visual inspection, the uncounted paper sheets may be counted again according to the instruction of the operator. good.
