FIGS. 4 and 5 are views for explaining the operation of the medium discrimination apparatus according to another embodiment of the present invention.

1 and 2, a medium discrimination apparatus 100 according to an embodiment of the present invention includes a discrimination unit 110, a transport unit 120, a first storage unit 130, a second storage unit 130, A second storage unit 140, and a third storage unit 150.

The distinguishing unit 110 can sense the media being transported. To this end, the distinguishing unit 110 may include a sensor 111 for sensing media. The sensor 111 may be, for example, an IR sensor.

The discrimination unit 110 can discriminate each of the transported media in real time. Although not shown in FIG. 1 and FIG. 2, the distinguishing unit 110 may include a sensor for discriminating media. At this time, the sensor for discriminating the medium may include at least one of a CIS sensor and a sensor including a Mechanic Optical Thickness Detector (MOTD).

The distinguishing unit 110 may acquire sensed data for discriminating the medium. The distinguishing unit 110 may acquire sensed data for discriminating a medium being conveyed regardless of whether the sensor 111 senses the medium. The distinguishing unit 110 may acquire the first sensing data and the second sensing data, which will be described below, through the CIS sensor and the thickness sensing unit. The first sensing data and the second sensing data may each include image data and thickness data for the medium.

Referring to FIGS. 1 to 3, the determining unit 110 may obtain sensing data (hereinafter, referred to as 'first sensing data') for each of the media. The distinguishing unit 110 may store the first sensed data in the first storage unit 130. [ For example, the first sensed data may be sensed data for the media that enter the discriminator 110, and may be the same as the sensed data until each medium enters the discriminator 110 and exits the discriminator 110 And may mean sensing data obtained in a predetermined interval.

Specifically, the discrimination unit 110 can sequentially discriminate the medium (a), the medium (b), and the medium (c) being transported. The discrimination unit 110 may store the first sensing data for the medium a, the medium b and the medium c in the first storage unit 130. [ The discrimination unit 110 may acquire the first sensing data at a predetermined time or a predetermined distance unit while the medium passes through the discrimination unit 110, for example. For example, the distinguishing unit 110 may identify and identify an identifier for each piece of sensing data obtained in units of 1 mm. For example, the identifier may include a predetermined time or a predetermined position, and may include position information of encoder slits for irradiating pulses for discrimination of media in the discrimination unit 110. [ The value of the identifier may be accumulated as media are discriminated in real time through the discrimination unit 110. [

The discrimination unit 110 may acquire sensed data (hereinafter, referred to as 'second sensed data') for each of the media in the discrimination period separately from the first sensed data. The distinguishing unit 110 may store the second sensing data in the second storage unit 140. [ The discrimination interval can be set in advance. For example, the discrimination period may be set in consideration of the performance of the sensor for discriminating the medium, for example, the CIS sensor and the thickness sensing unit, and may be determined by obtaining sensed data, (For example, a period up to tens or hundreds of millimeters after the sensor 111 detects the medium, a period up to several tens or several hundreds mm when the sensor 111 can not detect the medium, A section through which the medium passes for a set time). The discrimination unit 110 may acquire the second sensing data in units of 1 mm, for example, while the medium passes through the discrimination interval.

The discrimination unit 110 can discriminate each of the media using the second sensing data. For example, the discrimination unit 110 can discriminate at least one of the denomination, authenticity, and number of copies of each of the media.

If the media discrimination fails using the second sensing data, for example, skew or folding occurs in the process of passing the discrimination period, and the discrimination unit 110 discriminates the discrimination unit 110 in the discrimination period, (Hereinafter, referred to as 'third sensing data') of the first sensing data stored in the first storage unit 130 when the medium can not be discriminated from the third storage unit 150, Lt; / RTI > That is, the distinguishing unit 110 may extract the third sensed data from the first sensed data stored in the first storage unit 130, and store the extracted third sensed data in the third storage unit 150.

If the transport unit 120 does not receive the second sensing data even though the medium has passed through the discrimination unit 110, the transport unit 120 transmits sensing data (e.g., first sensing data) to the discrimination unit 110. [ May be requested. The distinguishing unit 110 may store the sensed data (e.g., first sensed data) in the buffer (not shown) in response to the storage request. For example, the discrimination unit 110 may store detection data (e.g., first detection data) for the medium from the time when the medium is brought into the discrimination unit 110 to the time when the storage request is received from the carry unit 120, ). ≪ / RTI > In this case, the carry section 130 uses the above-described identifier (for example, the detection data obtained from the point of time several hundred millimeters on the basis of the time when the discrimination is noticed) to the discrimination section 110 The second sensing data may be requested to be stored in the buffer (not shown), and the second sensing data may be extracted from the sensing data (e.g., first sensing data) stored in the buffer And can be used as the second detection data for the medium on which the discrimination has failed.

3, media (a) and medium (c) can be distinguished from each other because skewing or folding does not occur. However, skew occurs in medium (b) Can fail. In this case, the discrimination unit 110 stores the third sensed data in the discrimination interval and the additional discrimination interval for the medium (b) that failed in discrimination by using the above-mentioned identifier to the first sensing data And store it in the third storage unit 150. Here, the additional discrimination interval may mean a period in which the discrimination of the medium fails and further discrimination is performed.

The discrimination unit 110 may extract the third sensed data from the first sensed data stored in the first storage unit 130 and store it in the third storage unit 150 in response to a request from the carry unit 120 have.

The discrimination unit 110 may again discriminate the medium b using the third sensing data after the discrimination fails. For example, at the end of a series of transactions after the discrimination of the medium (e.g., medium (a), medium (b), and medium (c) (For example, medium (b)) that has failed to be discriminated by using the third sensing data after the end of the transaction of the financial instrument. Accordingly, it is possible to correctly discriminate the medium using the third sensing unit 150 using a larger amount of sensing data (i.e., the third sensing data) without restraining the amount of data by using the skew- have. In addition, it is possible to discriminate the medium which can not be discriminated due to insufficient detection data according to the storage data amount limitation of the second storage unit 140. [

The transport unit 120 includes a sensor 121 for sensing a medium entering the discrimination unit 110 and a sensor 122 for sensing a medium entering the transport unit 120 through the discrimination unit 110 ).

The transport unit 120 can determine the transport destination of the medium according to the discrimination result transmitted from the discrimination unit 110. Specifically, the carry section 120 can determine the destination of the medium according to the discrimination result transmitted from the discrimination section 110. [ For example, if the result of the discrimination is a failure, the carry unit 120 may transfer the medium to a reject medium collection cassette (not shown).

The first storage unit 130, the second storage unit 140, and the third storage unit 150 may store the first sensing data, the second sensing data, and the third sensing data, respectively. The first storage unit 130, the second storage unit 140 and the third storage unit 150 may be a flash memory type, a hard disk type, a micro type a microcomputer, a micro type, and a card type such as an SD card (Secure Digital Card) or an XD card (XD card)), a random access memory (RAM), a static random access memory (SRAM) At least any one of a memory of a read-only memory (PROM), a programmable ROM (PROM), an electrically erasable PROM (EEPROM), a magnetic random access memory (MRAM), a magnetic disk, Of a storage medium.

4, when a medium to which excessive skew is generated in the medium is not detected by the sensor 111 of the discriminating unit 110 but only by the sensors 121 or 122 of the transport unit 120 May occur. 5, when a medium to be conveyed due to excessive skewing is not detected by the sensors 121 and 122 of the carry section 120 but only by the sensors 111 of the discriminating section 110 May occur. This is because the vertical length may be longer than the interval between the sensors 111 and 122 and shorter than the interval between the sensors 121 and 122 depending on the type of paper money. Hereinafter, for the convenience of explanation, the operation of the distinguishing unit 110 and the carry unit 120 will be described taking the case of FIG. 4 as an example.

Referring to FIGS. 1, 2, and 4, the distinguishing unit 110 may sense a medium to be transported. As shown in FIG. 4, when an excessive skew occurs in the medium, the sensor 111 of the discerning unit 110 may not detect the medium. However, the CIS sensor and the thickness detecting unit (MOTD) of the discriminating unit 110 can obtain the first sensed data from the medium passing through the discriminating unit 110. [ The discrimination unit 110 may store the obtained first sensing data in the first storage unit 130. [ In addition, the discrimination unit 110 may acquire second sensing data for the medium in the discrimination period, and may store it in the second storage unit 140. [

The carry unit 120 may request the discrimination unit 110 to store the third sensing data when the medium is sensed by the sensor 122 in a state in which the discrimination result is not received from the discrimination unit 110. [ For example, the carry unit 120 may request the discrimination unit 110 to store the third sensed data. In other words, the carry section 120 may store the third sensed data, which is sensed data of a section required for discriminating the medium, among the first sensed data for the medium that has not been discriminated by the discriminating section 110 but has passed through the discriminating section 110, May be requested to the distinguishing unit (110). For example, the carry section 120 may store an identifier value (e.g., an encoder slit value) corresponding to the sensed data (i.e., third sensing data) of a section required for discriminating the medium, To request the discriminator 110 to store the third sensing data.

After the discrimination of all the media is completed (for example, after the transaction of the financial instrument is completed), the discrimination unit 110 discriminates the medium on which the discrimination has failed using the third sensed data stored in the third storage unit 150 Can be performed again. Therefore, a medium can be correctly discriminated using a larger amount of sensing data (i.e., third sensing data) for a medium that can not be discriminated by skew.

6 is a flowchart illustrating a medium discrimination method according to an embodiment of the present invention.

Referring to FIG. 6, a medium discrimination method according to an embodiment of the present invention includes: acquiring and storing first sensing data for each medium (S110); generating second sensing data for each of the mediums (S140), determining whether the media is successfully discriminated (S140), delivering the discrimination result to the transport unit (S150), and transmitting the discrimination result to the transport unit (S140) A step S160 of determining whether the discriminated medium is a normal medium, a step S160 of transferring the medium to a rejec cassette when the discriminated medium is not a normal medium, a step S180 separately storing third sensing data of the medium which has failed to discriminate, And a step (S190) of re-discriminating the medium which has failed to discriminate using the third sensing data.

As a result of the determination in step S140, if the determination is successful, step S150 may be performed. On the other hand, if it is determined as a result of the discrimination in step S140 that the discrimination fails, step S180 may be performed.

Hereinafter, steps S110 to S190 described above will be specifically described with reference to Figs. 1 to 3 and 6. Fig.

In step S110, the determination unit 110 may acquire first sensing data for each of the media to be transferred and store the acquired first sensing data in the first storage unit 130. [ The first sensed data may be sensed data for all media sensed by the discriminator 110. The first sensed data may be sensed data obtained until each of the media enters the discriminator 110 and exits the discriminator 110 May refer to sense data.

In step S120, the determination unit 110 may acquire second sensing data in the discrimination interval for each of the media to be transferred, and store the obtained second sensing data in the second storage unit 140. [ The discrimination period may be set in consideration of the performance of the CIS sensor and the thickness sensing unit, and may be a period during which the sensing data is acquired and the discrimination of the medium is performed using the sensed data (for example, To several tens or hundreds of millimeters).

In step S130, the determination unit 110 may identify each of the media using the second sensing data. For example, the discrimination unit 110 can discriminate the denomination, authenticity, and number of copies of each of the media.

In step S140, the distinguishing unit 110 may determine whether or not the currently discriminated medium is successfully discriminated. For example, if the medium is transported in a predetermined direction without skewing, folding, or the like and is discriminated within the discrimination interval, the discrimination unit 110 will judge that the discrimination is successful. Further, for example, a medium in which the discrimination fails due to the second sensing data obtained in the discrimination period due to skew, folding, or the like may occur. In this case, the distinguishing unit 110 will determine that it is a false discrimination.

In step S150, the distinguishing unit 110 may transmit the result of the discrimination to the carry unit 120. [

In step S160, the carry unit 120 may determine whether the discriminated medium is a normal medium based on the discrimination result.

In step S170, the transport unit 120 will transport the medium to the cassette for collecting the rejected medium when the discriminated medium is not a normal medium.

In step S180, the discerning unit 110 may separately store the third sensed data on the failed disc in the third storage unit 130. [ The third sensed data may mean sensed data for a medium in which the first sensed data stored in the first storage unit 130 fails to be discriminated. As described above, the discrimination unit 110 uses the identifier of the sensed data (for example, sensed data obtained from the point of time several hundred millimeters from the point in time when the discrimination is judged as unsuccessful) as the third detection Data can be extracted from the first sensed data.

In step S190, after the discrimination of all the media is completed (for example, after the transaction of the financial instrument is ended), the discrimination unit 110 can again discriminate the medium on which the discrimination has failed using the third sensed data have. Therefore, a medium can be correctly discriminated using a larger amount of sensing data (i.e., third sensing data) for a medium that can not be discriminated by skew.

7 is a flowchart illustrating a medium discrimination method according to another embodiment of the present invention. The description of the portion overlapping with the portion with reference to FIG. 6 will be omitted in order to avoid unnecessary repetition.

Referring to FIG. 7, a method of discriminating media according to another embodiment of the present invention includes a step S210 of detecting entry of a discriminative medium, a step S220 of acquiring and storing first sensed data for the medium, A step S240 of judging whether or not the medium is sensed by the discriminator 110 and the transport unit 120, and the step S240 of determining whether the medium is sensed by the transport unit 120, A step S260 of discriminating the medium using the third sensing data S260, a step S270 of determining whether the medium is a normal medium, And transporting the medium (S280).

If it is determined in step S240 that both the identification unit 110 and the transport unit 120 have detected a medium to be transported, step S270 is performed. On the other hand, if it is determined in step S240 that the media discrimination unit 110 does not detect the entry of the medium and detects the medium to be transported only by the transport unit 120, step S250 is performed.

Hereinafter, steps S210 to S280 described above will be specifically described with reference to Figs. 1, 2, 4, and 7. Fig.

In step S210, the sensor 111 of the discerning unit 110 may detect the entry of the medium into the discerning unit 110. [

In step S220, the distinguishing unit 110 may acquire first sensed data for the medium to be transferred and store the obtained first sensed data in the first storage unit 130. [

In step S230, the discerning unit 110 may acquire the second sensed data in the discrimination interval for the medium to be transferred, and store the obtained second sensed data in the second storage unit 140. [

In step S240, the sensor 122 of the carry section 120 may sense the medium conveyed through the discriminating section 110. [ For example, when the medium is sensed by the sensor 122 in a state in which the discrimination result is not transmitted from the discrimination unit 110, the carry unit 120 may not detect the medium by skewing, folding, . For example, when the discrimination result is transmitted from the discrimination unit 110, the carry unit 120 may determine that the discrimination unit 110 senses the medium.

In step S250, the carry unit 120 may request the discrimination unit 110 to store the third sensing data. For example, the carry section 120 may request the discrimination section 110 to store the third sensed data by using the CAN communication. In other words, the carry section 120 may store the third sensed data, which is sensed data of a section required for discriminating the medium, among the first sensed data for the medium that has not been discriminated by the discriminating section 110 but has passed through the discriminating section 110, May be requested to the distinguishing unit (110).

In step S260, after the discrimination of all the media is completed (for example, after the transaction of the financial instrument is completed), the discrimination unit 110 uses the third sensed data stored in the third storage unit 150, The discrimination of the medium can be performed again. Therefore, a medium can be correctly discriminated using a larger amount of sensing data (i.e., third sensing data) for a medium that can not be discriminated by skew.

On the other hand, in step S270, the carry unit 120 may determine whether the discriminated medium is a normal medium based on the discrimination result transmitted from the discrimination unit 110. [

In step S280, the transport unit 120 will transport the medium to the cassette for collecting the rejected medium when the discriminated medium is not a normal medium.
